This document summarizes a study that evaluated the effects of different levels of protexin probiotic supplementation in the diets of male geese on growth performance, carcass characteristics, and blood parameters. 98 male geese were fed diets with 0, 50, 75, or 100 g/ton of protexin probiotic and evaluated at days 15, 30, and 45. Probiotic supplementation significantly improved weight gain and feed efficiency but did not affect feed intake. Carcass and breast weights were also higher with probiotic. Blood parameters like cholesterol, triglycerides, calcium, phosphorus, and total protein were unaffected. In conclusion, protexin probiotic improved growth performance and carcass yield in male geese.

Effects of restricted feeding, low energy diet, and implantationNia Nia
This document describes a study that examined the effects of restricted feeding, a low-energy diet, and implantation of trenbolone acetate plus estradiol on growth, carcass traits, and circulating concentrations of insulin-like growth factor (IGF)-I and IGF-binding protein-3 in finishing barrows. Sixty-four barrows were divided into groups subjected to different feeding regimens, diets, and implantation. Blood samples were taken every 3 weeks and animals were slaughtered at approximately 105 kg. Restricted feeding decreased average daily gain, the low-energy diet reduced backfat thickness but decreased feed efficiency, and implantation decreased average daily gain, feed intake and backfat thickness while increasing feed efficiency.

An experimental study was carried over a
period of 42 days using 160 day-old commercial broiler chicks
(Ven Cobb) to study the effect of copper and flavomycin as feed
additives on growth performance in broiler chicken. The birds
were divided into four groups with four replicates of ten chicks in
each replicate. The treatment (T1) was control with standard
broiler ration and Cu as CuSO4 at 100 ppm, 200 ppm and
flavomycin at 10 ppm were supplemented in the basal diet to
form treatment 2 (T2), treatment 3 (T3) and treatment 4 (T4)
respectively.
The chemical composition of T1, T2, T3 and T4 rations
contained 15.43, 106.49, 212.54 and 18.69 ppm of Cu in broiler
starter and 12.67, 101.13, 202.72 and 20.20 ppm of Cu in broiler
finisher, respectively. The results of the present study revealed
that the supplementation of Cu as CuSO4 (100 and 200 ppm) or
flavomycin (10 ppm) showed no significant difference among the
treatment groups with regard to the feed consumption, body
weight gain and feed conversion ratio up to six weeks of age. The
carcass weight, slaughter weight, dressing percentage and giblet
yield were not influenced by dietary supplementation of either
Cu or flavomycin. It was concluded that dietary supplementation
of broiler chicken with Cu up to 200 ppm and flavomycin at 10
ppm did not have any adverse effect on production performance
of broiler chicken.

A description and the results of research carried out on broiler chickens in order to explore the efficacy of phytase products on ileal digestibility of phosphorus.
The reseach results found that phytase supplementation was effective in improving the growth performance, ileal phosphorus digestibility and the bone mineralization parameters when included in the low phosphorus diet.

Phytate is a natural dietary content and constitutes 0.4–6.4% (w/w) of most cereals and legumes (Eeckhout and Deaepe, 1994). It is poorly digestible for monogastric animals due to
a lack of effective endogenous phytase (Bitar and Reinhold, 1972). Phytate acts as an antinutritional factor, exerting its effects via a reduction in the solubility, and availability of
phosphorus (P), and to a lesser extent, Ca, Zn, Fe (Nävert et al., 1985; Hallberg et al., 1987; Hurrell et al., 2003). It was also reported that phytate could decrease the utilization of protein,
amino acids and starch. It has been suggested that phytate may bind with starch either directly, via hydrogen bonds, or indirectly, via proteins associated with starch (Thompson,
1988; Rickard and Thompson, 1997). Phytate is also known to inhibit a number of digestive enzymes such as pepsin, alpha-amylase (Deshpande and Cheryan, 1984) and increase mucin
secretion, excretion of endogenous minerals and amino acids in broiler chickens (Liu et al., 2008). Another issue is higher cost of dietary inorganic P which has been increased remarkably in last decade because of shortened phospate sources. Poultry industry has still been growing and reached huge mass production and contribution to environmental pollution has been heightened concerns because of the poor utilization of phytate phosphorus by poultry.
3 2011-comparative study of functional properties of commercial and membrane ...Bảo Dung Phan
Membrane processing of yellow pea protein isolates resulted in 28-68% lower phytic acid levels and generally enhanced functional properties compared to a commercial pea protein isolate. The membrane processed isolates had superior solubility, lower viscosity, better heat-induced gel formation, and lower gelling temperatures than the commercial isolate. Membrane purification using ultrafiltration and diafiltration is an effective way to improve the functional qualities of pea protein for use in foods.
This document describes a study that examined the impact of different crude protein levels in the diet on the growth of lambs. Fifteen male lambs were divided into three groups and fed diets with low (100g/kg), medium (130g/kg), or high (160g/kg) crude protein levels. During the first 6 weeks, lambs on the low and medium protein diets gained less weight than those on the high protein diet. For the rest of the trial period, lambs on the medium protein diet had the highest growth rate. Digestibility was similar for the medium and high protein diets and higher than the low protein diet. Results suggest that the optimum crude protein level for growing lambs is

Effects of Adding Different Levels of Phytase to Diet Containing Low Phosphor...Agriculture Journal IJOEAR
Abstract— This experiment was carried out to determine the effect of addition of different levels of phytase containing low phosphorus diets on performance, eggshell quality and bone characteristics in laying Japanese quail (Coturnix japonica). In the experiment, a total of 162 7-week-oldlaying Japanese quail were fed two different diets containing 0.33 % available phosphorus (AP, control) and 0.15 % AP supplemented with phytase 0, 500, 1000, 1500, 2000 phytase unites/g feed. Each diet was feed to groups having three replicates, each cages nine quail, in completely randomized design. Feed and water supplied for ad-libitum. Light was provided 17 hours daily. Egg production, egg mass, average daily feed consumption, viability, fat-free dried tibia weight were improved, as phytase level increased in the diet. However, final live weight, carcass weight, body weight gain, feed efficiency, tibia ash (%) and deformed egg ratio (%), some eggshell quality parameters measured in eggs collected at the end of the first period, were not affected by treatments. With regard to measured parameters, the responses of laying quail, to the increasing phytase levels, were not linear. The performance and bone parameters of the group fed with 1500 units were very close to that of the control group, even higher than the control group in some traits. Decreasing in shell weight of eggs collected at last three days of the experiment were not prevented any of the phytase levels. At the same period, shell thickness and breaking strength of the eggs of groups fed with 1500 and 2000 units phytase, were significantly lower than that of the control group. Manure ash percentage of phytase added groups were significantly lower than the control group.
Research has demonstrated that phytase is the only enzyme that is able to initiate
the release of phosphorus (P) from the phytate molecule, making it available for
absorption and utilization (Selle and Ravindran, 2007). The industrial demand for
phytases with greater potency in intestinal phytate hydrolysis and better heat
stability continues to stimulate the search for new enzyme sources. Enzyme
preparations with phytases derived from A. ficuum, Peniophora lycii and E. coli are
available commercially. More recently, new microbial 6-phytases produced by
synthetic genes, mimicking a gene from C. braakii or isolated from Buttiauxella,
were introduced into the market.
Effects of feeding a saccharomyces cerevisiaeRahardi Gautama
1) The study evaluated the effects of feeding a Saccharomyces cerevisiae fermentation prototype without antibiotics on the performance, health and carcass characteristics of beef heifers compared to a control diet containing antibiotics.
2) 1,495 crossbred heifers were fed one of two diets - a control diet containing monensin, tylosin and direct-fed microbials, or a diet containing an Saccharomyces cerevisiae fermentation prototype without antibiotics.
3) There were no differences between the diets for growth performance, carcass characteristics, morbidity or mortality. Heifers fed the prototype diet had numerically fewer liver abscesses. Replacing antibiotics with the fermentation prototype
Knowledge of amino acid (AA) digestibility of feed ingredients is necessary to feed broilers with
properly balanced compound diets. For this reason, more attention has recently been given to the
determination of AA digestibility of ingredients, recognizing that it may vary greatly depending
upon the feed ingredient. The effects of the inclusion of a mono-component serine protease
(Ronozyme® ProAct) on standardized ileal amino acid digestibility (SIAAD) of diets containing wheat
by-products (wheat DDGS (WDDGS) and wheat middlings (WM)) were evaluated in broilers.
- Improvement of SIAAD in the presence of protease is not the same for all AA and varies from one ingredient to another one. The effects of added protease are dependent on feed composition and on intrinsic digestibility of AA (COWIESON and ROOS (2014)).
- Factors such as type and quality of the ingredients, industrial processing and the presence of anti-nutritional substances such as tannins, phytates, trypsin inhibitors in plant species modulate the digestibility in poultry feed and thus the effectiveness of exogenous protease.
-The physiological state of animals (growth or maintenance), feed consumption or the nutritional feed quality could also influence the digestibility values.
This research evaluated the effect of a novel protease by DSM (RONOZYME® ProAct) on the performance, digestible energy and the ileal digestibility of crude protein, fat, gross energy and amino acids in broiler chickens. Read more to learn about the results.

This study examined the effects of varying dietary crude protein levels on indices of lipid metabolism and gene expression in broiler chickens. Male broiler chickens were fed diets containing 12%, 21%, or 30% protein, or were subjected to daily changes between 12% and 30% protein. Birds fed higher protein diets (21-30%) had lower rates of in vitro lipogenesis and lower malic enzyme activity compared to those fed lower protein diets (12%). Expression of genes for malic enzyme, fatty acid synthase, and acetyl-CoA carboxylase were constant with 12-21% protein but decreased when fed 30% protein (acute or chronic). The results demonstrate that dietary protein regulates lipid metabolism and gene expression

The document discusses the politics of redistribution in Brazil over several periods from 1985 to 2011. It notes that Brazil had colonial and unequal institutions that led to high inequality, but that inequality has been falling since 2000 due to several political factors. From 1985-1992, a new constitution and increased political participation supported reducing poverty and inequality. From 1992-2002, economic stability and bargaining led to increasing taxation and social reforms. From 2002-2011, pragmatic leadership under Lula da Silva expanded social spending and minimum wages to support redistribution and inclusive growth, though Brazil remains highly unequal.
Gene therapy is an experimental treatment that involves inserting genetic material into cells to give them a new or restored function, as damaged or missing genes can cause cancer. It works by using viral or non-viral vectors to deliver new genetic material into cells through various methods like electroporation, injection, or ultrasound. The goals are to modify tumor cells, add missing tumor suppressor genes, make cells more sensitive to treatment, inhibit angiogenesis, or enhance the immune response against cancer.

It identifies four initial case studies of redistribution episodes using inequality data and outlines a framework to analyze the political context, instruments, and process of reform in each country case. The framework focuses on the nature of inequality, political economy drivers, and role of leadership and coalitions in setting agendas and sustaining redistributive policies over time.
Post-translational Modifications in Crop ImprovementFaraZ AhmaD
Post-translational modifications (PTMs) are chemical changes that occur to proteins after translation. PTMs play an important role in increasing the functional diversity of proteins by altering properties like activity, localization, and stability. Common PTMs include phosphorylation, glycosylation, ubiquitination, and methylation. These modifications influence many cellular processes and are critical for understanding diseases and improving crops through stress tolerance. PTMs are regulated by enzymes and can affect signaling, metabolism, and stress response pathways in plants.
The document discusses various methods of immobilizing enzymes and whole cells, including physical and chemical methods. Physical methods include adsorption, entrapment, and microencapsulation, which attach the enzyme without covalent bonds. Chemical methods include covalent binding and cross-linking, which use covalent bonds to strongly attach the enzyme. The properties of immobilized enzymes depend on the method used, with covalent binding providing the strongest attachment but potentially reducing enzyme activity. Immobilization provides benefits such as reusability and stability under process conditions.

Finally, it provides an overview of the general uses of aggregates in compacted bases and mixes, hot mix asphalt, Portland cement concrete, and other applications.
The document summarizes a study on the comparative efficacy of different growth enhancers on broilers. 96 day-old broiler chicks were divided into 4 treatment groups: a control group given plain water, and groups given Atovi, aloe vera, or sorghum syrup supplements. Results showed no significant differences in weekly weight gain, feed consumption, or feed conversion ratio among treatments. The sorghum syrup group had the highest final weight, while the aloe vera group had the lowest. The Atovi group yielded the highest return on investment. In conclusion, using growth enhancers can increase profits compared to plain feed, though higher supplement concentrations may be needed to see effects.
This study investigated the effects of adding different percentages of cumin oil (0%, 15%, 30%, 45%) to broiler diets on growth patterns and curves. Profile analysis showed the growth curves were not parallel, indicating the treatments had different effects. Birds receiving diets with 45% cumin oil had significantly higher weekly and final body weights than the control group. Various growth curve models (Gompertz, Verhulst, weighted least squares, linear) were fitted to the data, and the weighted least squares model provided the best fit with the lowest error. This suggests adding 45% cumin oil to broiler diets may improve profitability by increasing final body weight.
Comparative Study of Feeding Different Levels of Black Cumin (Nigella sativa)...BRNSS Publication Hub
The present work was aimed to determine the comparative effect of feeding different levels of black cumin
on growth, feed consumption, and feed efficiency of COBB-500 broiler. Three hundred and twenty, daysold straight run COBB-500 chicks from a lot of the same hatch were brooded in an electrically operated
battery brooder for a period of 7 days, where pre-experimental diet was offered. On the 8th day, chicks
having uniform body weight were randomly allocated into four dietary treatments with four replications
(20 chicks in each). The isoproteinous and isocaloric formulated standard starter (1–10 days), grower
(11–20 days), and finisher (21–42 days) diets were supplemented with different levels of black cumin of
T1 – control, T2 – 0.25% black cumin, T3 – 0.5% black cumin, and T4 – 0.75% black cumin, respectively.
The chicks were offered ad libitum treatment diets and clean drinking water. The desired data were
recorded weekly, which included live weight, weight gain, feed consumption, and feed efficiency of
broiler birds. The obtained data were subjected to statistical analysis under completely randomized design
as per the methods of MSTAT. Final live weight of the birds was found highly significant (P < 0.01) for
all treatment groups. Highest final weight gain (2244.59 g) was found in birds fed ration supplemented
with 0.5% black cumin. Daily live weight of the birds was also found highly significant (P < 0.01) for all
treatment groups. Highest daily live weight gain (60.27 g) was found in birds fed ration supplemented
with 0.5% black cumin. Supplementation of black cumin in the broiler rations did not exhibit any
significant effect (P > 0.05) on the total feed consumption. Feed conversion ratio was found significantly
different (P < 0.01) for all treatment groups. It is, therefore, concluded that inclusion of black cumin in
the broiler rations could be economical and efficient production of broilers
Australian spray dried porcine plasma offers solutions to nutritionist and pi...Milling and Grain magazine
Spray dried plasma proteins are a relatively new feed ingredient available to Australian farmers. Sonac Australia (Darling Ingredients) is the only company in Australia currently producing spray dried plasma proteins from a range of species including pigs, cattle and sheep for domestic and export markets. The introduction of spray dried porcine plasma to the pig feed industry in Australia has been a huge nutritional and welfare advantage to the pig industry. Local research trials conducting across Australia in a range of settings (research & commercial) have delivered consistent improvements in performance and health. At generous inclusion rates (3-5%) spray dried porcine plasma when offered in well-balanced piglet diets can significantly enhance feed intake and aid in maintaining gut function, integrity and development (Edwards et al., 2012; Hernandez et al., 2010).
This study aims to investigate the direct and residual effects of dietary brewer's dried grain (BDG) on broiler performance, nutrient retention, feed intestinal transit time, and economics. Specifically, the study will:

Concept paper, Effect of dietary selenium supplementation on follicular in goatMubasher Solangi
This concept paper proposes a study on the effects of dietary selenium supplementation on follicular growth in goats. The study aims to improve reproductive performance in small ruminants by achieving early maturity and maximizing fertilization through improved follicular growth. Thirty female goats will be divided into three groups - one control group fed a low concentrate diet through grazing, one treatment group also grazing but with selenium supplementation, and one treatment group confined with a high concentrate diet and selenium supplementation. Ovarian morphology, follicular development, hormone levels, and antioxidant status will be analyzed and compared between the groups both during and outside the breeding season to evaluate the effects of selenium supplementation.
Comparative Effect of Some Proprietary Vitamins and Trace Mineral Mixtures on...iosrjce
The research study was carried out to evaluate the comparative effect of some proprietary
vitamins/trace mineral mixtures on the performance and egg quality of laying hens. Two hundred and fifty- six
fifty weeks old Yaffa strain laying birds were used. The birds were randomly allotted to four premixes fortified
experimental diets; PPGODOMIX, PPOMIX, PPROCHE and PPWRITEX with each diet containing isocaloric
and isoproteinous. Sixty four birds were randomly assigned to each of the dietary treatments. The birds were
further sub- divided into four replicates with sixteen birds per replicate. The four dietary treatments elicited no
significant (P>0.05) influence on the overall performance of birds. Percentage hen day egg production was
equally not significantly (P>0.05) affected by any of the dietary treatments examined. The average daily feed
intake was significantly (P<0.05)><0.05)>0.05) influenced by PPOMIX. Birds fed PPOMIX obtained a significantly (P<0.05) higher
value of egg weight, albumen weight and blood spot which were statistically similar to other experimental
premixes examined. The results generated from this study revealed that premix of similar profile will give
similar result which could be used to improve ration management towards enhanced feed utilization and egg
internal/external quality.
Diet Affects Intestinal Health Lab Animal 2016Mike Pellizzon
The document discusses the importance of carefully selecting laboratory animal diets for research experiments. It compares standard chow diets to purified diets, noting that chow diets contain varying levels of fiber, phytoestrogens, and heavy metals that can differ between batches. Purified diets have consistent, defined ingredients that allow researchers to control the diet's nutrient composition. However, purified diets typically contain only insoluble fiber unlike chows, which can impact gut health and experimental results. Recent studies show that adding soluble fiber to purified diets prevents adverse effects on the gut seen with low-fiber purified diets alone. Researchers must consider how an animal's diet can influence experimental outcomes.
This study evaluated the effects of different formulated feed rations on albino rats. Sixteen rats were divided into four groups and fed different feed formulations for 21 days. Group II, which was fed a diet of 600g corn, 200g millet, 160g crayfish and 40g groundnut, showed the most positive effects on growth performance and health biomarkers compared to the control group. While Group I and III showed some increased biomarkers suggesting potential liver damage, Group II most closely mimicked the effects of the control commercial feed. The study concludes that Group II's formulated feed is a suitable substitute for rat feed.
This study evaluated the effects of including bamboo leaf meal (BLM) in broiler chicken feed on performance, stress indicators, hematology, and carcass characteristics under heat stress conditions. Broiler chickens fed diets containing 1-2% BLM had higher weight gain, feed intake, and better feed conversion rates compared to those fed a 0% BLM diet. Increasing BLM in the diet also lowered rectal temperatures and corticosterone levels in the chickens during heat exposure. However, hematology, carcass characteristics, and most stress indicators were not significantly affected by dietary BLM inclusion levels up to 2%. Overall, the results suggest that BLM can help alleviate the negative impacts of heat stress on broiler chicken
THE EFFECT OF PROTEIN DIGESTION ON ZEBRAFISH METABOLIC RATE
INTRODUCTION
protein form one of the primary nutrients that are used in the body for cellular structures building (Acheson 525). the process of protein digestion involves the breakdown of food substances we eat into soluble solutions that can be absorbed in the bloodstream. protein is broken down to form amino-acids within the digestive systems and the amino acids are absorbed into the hepatic portal system. the proteins are the building blocks in the body and they include food substances such as eggs, meat, milk as well as beans and nuts among many other food products (Acheson 527). the digestion of proteins mainly begins in the stomach and continues in the small intestine (Acheson 530). digestion of proteins is facilitated by pepsin enzymes that promotes the digestion of the large proteins molecules into amino acids. the digestion of proteins in the body also includes the use of hydrochloric acid (Acheson 526). zebra-fish is preferred in research studies since it is cheap, have similar organs as human beings and produces a lot of offspring. zebra-fish also has a short life-span of about two years and are easy to take care of.
Therefore, the primary objective of this research paper is to evaluate the effects that protein provide on the fish metabolic rate especially after three to four hours.
STATEMENT OF THE PROBLEM
In most cases, protein digestion takes place in both the stomach and in the small intestine in the body of human beings. However, in Zebra fish, protein digestion involves the use of associated organs. the dietary ingredients, and nutrients as well as anti-nutritional remain important factors that affect Zebra fish growth and development. However, there lacks proper nutritional control due to the absence of standardized reference diet (Boyle et al.,2008). Moreover, according to epidemiological studies by Richard et al. (2015), prenatal conditions are important in the growth and development of Zebra fish. As a way of providing a standardized dietary framework, a need emerges for the provision of specific dietary and nutritional standard aimed at improving the growth and development of Zebra fish. Thus, this project aim to evaluate how the level of? protein in commercial fish foods affects the metabolic rate of Zebra fish (Danio rerio).
BACKGROUND
The consumption of proteins could have significant effects on body metabolism. proteins commonly require more calories for breakdown than carbohydrates and this could have significant effects on various metabolic aspects, including an increase in the metabolic rate of organisms (Williams et al., 2014). Due to the strong bond making the protein molecules, a lot of energy is required to break down the high protein that has been consumed. about 30% of the calories in proteins are burned in the process of digesting proteins(Acheson et al. 528). The heat generated in the process increases the general body heat output h ...

This study evaluated the effects of different levels of probiotic (Protexin) supplementation in broiler feed on blood parameters. 375 broilers were divided into 5 treatment groups that received either 0, 25, 50, 75 or 100 g/ton of probiotic in their feed. Blood samples were collected and analyzed. Results showed that hematological values, serum urea, creatinine, triglycerides, HDL, cholesterol and LDL were not affected by treatments. However, hemoglobin, serum glucose and total protein were significantly increased in birds receiving 100 g/ton probiotic compared to the control group. In conclusion, probiotic supplementation at different levels may improve some blood parameters of broilers.
This study aims to investigate the direct and residual effects of dietary rice husk on broiler performance, nutrient retention, feed intestinal transit time, and economics. Specifically, it will:
1) Evaluate the direct impact of feeding broilers 0-5% rice husk from 0-3 weeks on performance, nutrient retention, and intestinal transit time.
2) Assess the residual effects when birds previously fed rice husk are given a standard diet from 4-6 weeks.
3) Determine the correlation between intestinal transit time and nutrient retention/performance when broilers are fed different rice husk levels.
The experiment will involve feeding 96 broilers diets with 0, 5, 10 or 15% rice husk
A study was carried out to evaluate the nutritive value and enzyme supplementation of different sources of energy in broiler diets on the growth performance and heamatological parameters of broiler chickens supplemented with Mazigrain® enzyme within the treated groups. Five isonitrogenous and isocaloric diets less (23.17 % CP; 2831 Kcal/ME and 21.73 % CP; 2929 Kcal/ME) for the broiler starter (0 - a month) and finisher phases (5–8 months) respectively were formulated. Diet 1(maize based diet) served in as the control while diets 2, 3, 4 and 5 were supplemented with sorghum, pearl millet, cassava and sweet potatoes based diets separately. A sum of 225 day-old NAPRI X broiler chicks were haphazardly distributed to the five treatments. Every treatment comprised of 45 broilers with three repeats of fifteen birds each in a Completely Randomized Design (CRD). The general linear model protocol of S.A.S. 9.0. was used to analyze the collected data. Among the dietary groups significant changes (P<0.05) was found utilizing a Tukey test. Enzyme along with various energy sources have noteworthy (P<0.05) changes on every one of the parameters (final weight, daily weight gain, feed conversion ratio, water intake, water to feed ratio and feed cost per kilogram weight gain) except for death rate at the starter phase. Broilers that had sorghum based diet had the best performance at starter stage (final weight; 627 g, weight gain; 576.85 g, feed cost/kg gain; ^ 187.95 k). At the finisher stage, sorghum supplemented with enzyme had the best feed conversion ratio (1.96) and feed cost/kg gain; ^ 171.15 k. The optimal performance characteristics were recorded for sorghum based diets. Feed cost / kg gain was the cheapest on birds fed sorghum based diet with enzyme supplementation which was comparable with those fed the maize based diet. However, the use of enzyme enhanced the performance of birds at both the starter and finisher phases.

We are what we eat - The role of diets in the gut-microbiota-health interactionNorwich Research Park
Lecture at Summer School Nutrigenomics in Camerino Italy Sept. 2016.
The (small) intestine has increasingly been recognized to play a key role in the early phase of pro-inflammatory disturbances e.g. by enhanced overflow of dietary components to the distal intestine (ileum, colon) and affecting the gut microbiota & their metabolites (e.g. bile acids, short chain fatty acids). Transcription factors e.g. PPARγ, FXR, AHR or NRF2 are involved in host sensing mechanisms of microbial metabolites. Strong impact of dietary composition on small and large intestinal microbiota and their metabolic functions.
Targeting the (small) intestine and its microbiota with (plant) foods, bioactives, probiotics and drugs will improve gut and liver functions with strong implications for human health during life.
