The objective of a defined feeding management program is to supply a range of balanced diets that satisfy the nutrient requirements at all stages of development & that optimize efficiency and profitability without compromising bird welfare or the environment.
In the tropical climate like India, the high ambient temperature along with high humidity is the major stressor (abiotic), thus resulting in the HEAT STRESS a major concern of poultry production.

ENVIRONMENT STRATEGIES:
A). Intermittent Photo schedule
An intermittent light regime can improve the feed efficiency and thus the broiler production efficiency, by decreasing the fat deposition associated with increased incidence of leg abnormalities, metabolic and cardiovascular diseases, ascites.
The favourable effect is related to the lower heat production during both light and dark period, although fluctuations in heat production are following closely the light-dark alternation.
This photo schedule contains more than one scotophase and one darkphase which recur at 24 hr intervals.
This regime increases the feed consumption during cooler part of the day.
Symmetric - when scotophase and dark phase are of equal length.
Asymmetric - when they are not in equal length.
3weeks age of broiler raised under 2L:4D intermittent light regime were significantly lighter than broilers raised in continuous light schedule but at 7 weeks it is reverse.(Proudfoot, 1975).
The initial reduction in body weight gain of birds under intermittent schedule is followed by compensatory growth, but the compensatory growth depends on genotype and sex.
Boschouwers and Nicaise (1992) observed that physical activity in broilers were lowest under 100Hz fluoroscent light and highest under incandescent.

Exogenous carbohydrases such as xylanases, amylases, and glucanases have been reported to improve energy utilization and performance of broiler chickens (Olukosi et al., 2008; Vieira et al., 2015). These enzymes may improve the access of endogenous enzymes to cell contents due to hydrolysis of cell wall arabinoxylans (Kocher et al., 2003) as well as to augment endogenous amylase in young birds (Gracia et al., 2003). Decreases in endogenous amino acid losses may also contribute to the beneficial effects of amylases (Jiang et al., 2008).

Hatchability is certainly a key performance and profitability
parameter for chick producers. Storing hatching eggs is a
current necessary practice and this can damage hatchability
results. Canthaxanthin, as an antioxidant, is particularly
effective for supporting hatchability. The vitelline membrane
strength (VMS) is very important to the early embryo survival.
The vitelline membrane protects the embryo (pH 6) from the
high pH of the albumen (pH 9.4) and therefore has to be
strong enough. The embryo progressively gets surrounded
by the yolk sac and is totally protected in the yolk sac between
day 3 and 4 of incubation.
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.
Hatchability is certainly a key performance and profitability parameter for chick producers. Storing hatching eggs is a current practice and this can damage hatchability results. Canthaxanthin, as an antioxidant, is particularly effective for supporting hatchability. The vitelline membrane strength (VMS) is very important to the early embryo survival that can-thaxanthin can promote it. The experiment involved a flock of 3,800 breeders (males and females) separated into two adjacent blocks. Feeding experiment started at 18 weeks of age with a control diet as 3000 IU/kg Vitamin D3 and no Carophyll® supplementation and experimental diet as 1,600 IU/kg vitamin D3, 37.5 μg/kg 25-hydroxy-vitamin D3 (HyD®) & 6 mg/kg canthaxanthin (Carophyll® Red 10%). Vitamin D3 or 25-hydroxy-vitamin D3 were not expected to have any influence on the VMS. Eggs were collected at 40/45 weeks and stored 7 days. The VMS was evaluated using a com-pression machine. Stiffness and breaking strength were significantly increased with the supplementation of canthaxan-thin. Thanks to the unique capabilities of high deposition rate in the yolk and singlet oxygen quenching capabilities, canthaxanthin from Carophyll® can improve the VMS in complement to Vitamin E and we hypothesized that it contrib-utes to explain its influence on early embryo viability and hatchability in breeder performance.
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.
Variation in trypsin inhibitor activity (TIA) and protein solubility within commercial soybean meals (SBM) is believed to affect animal performance. The objective of this research was to investigate the proteolytic effect of purified pancreatic trypsin/chymotrypsin and a purified protease from Nocardiopsis prasina on 9 commercial SBM samples varying in chemical composition, TIA and protein solubility characteristics. SBM was incubated with or without protease (pH 7, 3 hours, 40°C) and the supernatants were analyzed by SDS-page and for level of free soluble amino ends using the o-phthal-dialdehyde method. SDS-page analysis showed differences in the amount and composition of the soluble protein fraction of the SBM. The proteolytic efficiency of the lower dosages of pancreatic protease varied extensively between SBM batches whereas at the highest dose the efficiency was comparable for all SBM. The difference could not be explained by differences in protein solubility and TIA values as isolated variables, but the data strongly suggest that the hydrolysis of soya protein by pancreatic proteases depends on the commercial batch of SBM used. Incubation with N. prasina protease showed similar response for the different SBM, the main difference being a somewhat lower effect at high protease dose for one of the SBM batches, which might be in part explained by its distinct lower protein solubility
Viscosity reduction by three feed enzymes was measured in a high throughput pressure sensing system using commercial dosages on purified polysaccharides (arabinoxylan and ß-glucan). Fluorescence and antibody microscopy techniques were also used to visualize effects on the solubilisation of endosperm cell walls of wheat and barley.
Viscosity data clearly demonstrated depolymerisation of mixed-linked ß-glucans by the two multicomponent enzymes. The two multicomponent enzymes also reduced the viscosity of the arabinoxylan solution, while the monocomponent xylanase most effectively depolymerised the arabinoxylan. Microscopy data revealed that the multicomponent enzyme chosen for the studies could solubilize barley cell walls by targeting both the ß-glucan strutures as well as the arabinoxylans. The xylanase could effectively solubilise barley cell walls by merely attacking the arabinoxylans.
Phytase efficiency to increase phosphorus utilization in
poultry has been proven for decades. In addition,
phytase was demonstrated to improve growth
performance, meat breast weight, amino acids
digestibility and plasma myo-inositol concentration.
The objective of this work was to investigate potential
interactions between phytase supplementation, growth
performance and host gene expression to identify
potential associated biomarkers.

We investigated the effects of protease (Ronozyme ProAct, PRO) supplementation on the AID of 3 cereals in the presence or not of a multi-enzyme complex with β-glucanase and β-xylanase activity (GLU+XYL). The AID of most of AA was higher for corn and wheat than for barley. The inclusion of GLU+XYL increased the AID of DM, CP and of all the AA, except Met and Lys. The inclusion of PRO increased the AID of Gly and tended to increase that of most of the other AA. The combination of both enzymes did not improve further AA digestibility any.

This research is carried out in order to improve the production of eggs in indigenous chicken by reducing the
inter-sequence stopped days through use of anti-prolactin agent (Bromocriptine) and serum from laying hen.
Sixty-four indigenous (deshi) chickens of 20-22 weeks of age, were randomly assigned into four groups (i, j, k
and l) and each group consisting of 16 hens. Control was designated as Group I and Bromocriptine orally at a
dose of 641μg/bird/day was used to treat group j, group k was treated with serum of laying kadhaknath hen
serum at a dose of 1 ml intramuscularly/bird/day and group l was treated with both Kadhaknath serum and
Bromocriptine at doses given to group j and k for the period of 15 March, 2019 to 16 June, 2019 and egg
production, stopped days, prolactin level, hematological parameter and egg qualities were observed. A
significant increase (p<0.05) in Egg production was noticed in all treated groups in comparison to the groups
which were in non- treated control and group k showed the highest production. All treatment groups depicted a
significant decrease (p<0.05) in stopped days and prolactin levels and lowest were observed in hens of group l.
In hematological values between the chicken group, no significant differences were noticed. The present study
reveals that combined treatment with Bromocriptine and serum from laying kadhaknath hen increases egg
production without affecting the health of indigenous chickens.
Lupins are a high protein, high energy, nitrogen-fixing grain legume with a protein and oil composition that can effectively compete with imported soya as part of livestock and fish diets. As a result, lupins have considerable potential to provide a comparable UK-grown vegetable protein source for farmed animals and aquaculture, as well as providing other advantages as arable break crops. With the proposed CAP greening reforms and the requirements of the new Basic Payment Scheme in respect of Ecological Focus Areas, there has never been a better time to look at legumes in crop rotations and lupins in particular tick several boxes.

Presentation during the IV International Symphosium on Nutritional requirements of Poultry and Swine on March 29th - by Gilberto Litta DSM Animal Nutrition.
Main Message of the presentation is the importance of vitamin in Poultry Nutrition as well as the multiple benefits achievable.
Introduction
The mineral content in animal body is 2-5%.
• Most abundant minerals in
body:
– 36-39% Ca (bone ash)
– 17-19% P (bone ash)
Conclusion
STTD Ca requirements for 11 to 25 kg pigs:
– ADG is between 0.36 and 0.56%, G:F is 0.43%
– Bone ash, bone Ca, and bone P is between 0.48 and 0.56%
– Ca retention and P retention is between 0.48 and 0.52%
Recent research on vitamin requirement of modern swine breeds under current husbandry conditions is limited; tabular recommendations may underestimate the actual needs of growing pigs and breeding sows.
Clinical / subclinical vitamin deficiency can still occur within industrial swine production:
optimum vitamin supplementation prevents from deficiency and
exploits the genetic performance potential of swine.
Superior dietary supplementation levels of certain vitamins do provide additional value, such as improved stress and disease resistance, adequate welfare or better product quality.
Feeding strategy
• Animal Requirements change with criteria: need to take into account various parameters to optimise performance
- need to take into account complexity due to variability of response and interaction,
no single dose response
- Availability of new tools to integrate complexity (model for dietary formulaƟon)
• Feed recommendation in sustainable system should integrate three objectives: production performance, environment and welfare
Product quality
• Limited influence on lipid fraction
• Effects on oxidation remains controversial
- anƟoxidant vs pro-oxidant
- interacƟons between level and duration of trace elements dietary level, issue, slaughtering conditions, product packaging and transformation, cooking.
• Good potential of product enrichment in trace mineral but limitation due to Regulation in
animal and human feeding and due to toxicity level for animals
General conclusions
- Current methods used by the industry to evaluate protein quality are not capable of detecting existing differences among SBM
- The composition and the protein quality of SBM vary with the origin of the bean
- Different matrixes should be used for SBM of different origins, NIR technology might help
- Proteases might improve the uniformity and nutritive value of SBM batches
Conclusions
• Each additive affects microflora in a different manner
• Succesful and Sustentable Additives should contribute to mantain microflora diversity
• Some additives may also affect the host directly, not only the microbial communities
• Effects at host level should be understood and used to improve holistic efficiency
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.
Protein/amino acids are among the most expensive nutrients to deliver in poultry nutrition
The digestibility of protein in poultry is typically incomplete by the terminal ileum
Undigested protein that leaves the ileum is from both exogenous (diet) and endogenous (bird) sources
Understanding the digestion of dietary proteins and the recovery of endogenous proteins is important and can provide a basis for the use of exogenous proteases
>Since the ban of antibiotic growth promoters (AGPs) in the European Union, the industry has been looking for valid alternatives to improve health, immune status and performance in animal agriculture.
>The industry focuses on developing solutions that mimic the effects of AGPs. However, the exact mode of action of the AGPs to improve poultry performance is not fully understood.
Most AGPs alternatives try to prevent the proliferation of pathogenic bacteria and to modulate indigenous bacteria to improve immune status and performance.
>As an industry, we have made limited progress in improving gut health. Maybe we need to change the approach to find the most optimal solution.
>As part of a stable ecological system, pathogens per se do not represent a threat to animal health. The dynamic nature of the gastrointestinal microflora in chickens makes maintaining the right balance in the microbial ecosystem.
>Despite a large amount of scientific work has been done on the topic, a lack of consistent improvement has been registered.
>To improve gut health more consistently, a broader approach, involving a combination of nutrition, feed technology and husbandry management needs to be taken.
>In addition, gut-health is too complex to be solved from
only one point of view. Input should be obtained from different disciplines, including food technology, human nutrition, veterinary and human medical sciences.
>DSM will start an holistic program to come to tailor made solutions to improve the gut ecosystem with the objective of reducing the use of antibiotics in the poultry industry.

Deep Behavioral Phenotyping in Systems Neuroscience for Functional Atlasing a...Ana Luísa Pinho
Functional Magnetic Resonance Imaging (fMRI) provides means to characterize brain activations in response to behavior. However, cognitive neuroscience has been limited to group-level effects referring to the performance of specific tasks. To obtain the functional profile of elementary cognitive mechanisms, the combination of brain responses to many tasks is required. Yet, to date, both structural atlases and parcellation-based activations do not fully account for cognitive function and still present several limitations. Further, they do not adapt overall to individual characteristics. In this talk, I will give an account of deep-behavioral phenotyping strategies, namely data-driven methods in large task-fMRI datasets, to optimize functional brain-data collection and improve inference of effects-of-interest related to mental processes. Key to this approach is the employment of fast multi-functional paradigms rich on features that can be well parametrized and, consequently, facilitate the creation of psycho-physiological constructs to be modelled with imaging data. Particular emphasis will be given to music stimuli when studying high-order cognitive mechanisms, due to their ecological nature and quality to enable complex behavior compounded by discrete entities. I will also discuss how deep-behavioral phenotyping and individualized models applied to neuroimaging data can better account for the subject-specific organization of domain-general cognitive systems in the human brain. Finally, the accumulation of functional brain signatures brings the possibility to clarify relationships among tasks and create a univocal link between brain systems and mental functions through: (1) the development of ontologies proposing an organization of cognitive processes; and (2) brain-network taxonomies describing functional specialization. To this end, tools to improve commensurability in cognitive science are necessary, such as public repositories, ontology-based platforms and automated meta-analysis tools. I will thus discuss some brain-atlasing resources currently under development, and their applicability in cognitive as well as clinical neuroscience.
The ability to recreate computational results with minimal effort and actionable metrics provides a solid foundation for scientific research and software development. When people can replicate an analysis at the touch of a button using open-source software, open data, and methods to assess and compare proposals, it significantly eases verification of results, engagement with a diverse range of contributors, and progress. However, we have yet to fully achieve this; there are still many sociotechnical frictions.
Inspired by David Donoho's vision, this talk aims to revisit the three crucial pillars of frictionless reproducibility (data sharing, code sharing, and competitive challenges) with the perspective of deep software variability.
Our observation is that multiple layers — hardware, operating systems, third-party libraries, software versions, input data, compile-time options, and parameters — are subject to variability that exacerbates frictions but is also essential for achieving robust, generalizable results and fostering innovation. I will first review the literature, providing evidence of how the complex variability interactions across these layers affect qualitative and quantitative software properties, thereby complicating the reproduction and replication of scientific studies in various fields.
I will then present some software engineering and AI techniques that can support the strategic exploration of variability spaces. These include the use of abstractions and models (e.g., feature models), sampling strategies (e.g., uniform, random), cost-effective measurements (e.g., incremental build of software configurations), and dimensionality reduction methods (e.g., transfer learning, feature selection, software debloating).
I will finally argue that deep variability is both the problem and solution of frictionless reproducibility, calling the software science community to develop new methods and tools to manage variability and foster reproducibility in software systems.

Nutraceutical market, scope and growth: Herbal drug technologyLokesh Patil
As consumer awareness of health and wellness rises, the nutraceutical market—which includes goods like functional meals, drinks, and dietary supplements that provide health advantages beyond basic nutrition—is growing significantly. As healthcare expenses rise, the population ages, and people want natural and preventative health solutions more and more, this industry is increasing quickly. Further driving market expansion are product formulation innovations and the use of cutting-edge technology for customized nutrition. With its worldwide reach, the nutraceutical industry is expected to keep growing and provide significant chances for research and investment in a number of categories, including vitamins, minerals, probiotics, and herbal supplements.

Phenomics assisted breeding in crop improvementIshaGoswami9
As the population is increasing and will reach about 9 billion upto 2050. Also due to climate change, it is difficult to meet the food requirement of such a large population. Facing the challenges presented by resource shortages, climate
change, and increasing global population, crop yield and quality need to be improved in a sustainable way over the coming decades. Genetic improvement by breeding is the best way to increase crop productivity. With the rapid progression of functional
genomics, an increasing number of crop genomes have been sequenced and dozens of genes influencing key agronomic traits have been identified. However, current genome sequence information has not been adequately exploited for understanding
the complex characteristics of multiple gene, owing to a lack of crop phenotypic data. Efficient, automatic, and accurate technologies and platforms that can capture phenotypic data that can
be linked to genomics information for crop improvement at all growth stages have become as important as genotyping. Thus,
high-throughput phenotyping has become the major bottleneck restricting crop breeding. Plant phenomics has been defined as the high-throughput, accurate acquisition and analysis of multi-dimensional phenotypes
during crop growing stages at the organism level, including the cell, tissue, organ, individual plant, plot, and field levels. With the rapid development of novel sensors, imaging technology,
and analysis methods, numerous infrastructure platforms have been developed for phenotyping.

What is MaxiChick ?
MaxiChick® is the patented combination of two
scientifically proven DSM products (Hy•D®
and
Carophyll® red) that complement each other to boost
the productivity of the breeder flock.
By feeding Hy•D® (25-OH-D3) the liver metabolism of
vitamin D3 is by-passed. Birds always have optimized
level of circulating 25-OH-D3.
By feeding Carophyll® red (canthaxanthin), the bird
will have the carotenoid with the highest deposition
rate, playing an important antioxidant roll in both
males and females.
8. MaxiChick®
Practically all Lipids are Located in the Egg Yolk
(Surai, 2012)
Carotenoids such as Canthaxanthin, are deposited directly in the yolk, to act as an
antioxidant, altogether with Vitamin E

• Using the MaxiChick calculator with
the following assumptions:
-Ross 308 performing at standard
-Improvement of +1 settable eggs
-Improvement of +1% fertility
-Improvement of +1% hatchability
• That means 4.1 and 100 chicks more
per housed hen and per MT of feed
respectively
• At 0.30 € per chick and 6€/Mt
inclusion rate, that means an
ROI of 5 to 1
31. Return on Investment- Layers
• Using the MaxiChick calculator
with the following assumptions:
-Hy Line performing at standard
-Improvement of +1 settable eggs
-Improvement of +1% fertility
-Improvement of 2% hatchability
• That means 3.65 and 110 chicks
more per housed hen and per MT of

Objective
This trial assesses the effects of 60ppm
CAROPHYLL
Red
on
reproductive
characteristics in adult broiler breeder
males
Lipid peroxidation is considered a major
cause of infertility, possibly limiting the
viability of chicken spermatozoa
• CAROPHYLL Red is a potent radical
scavenger and powerful antioxidant
Results
• The viable sperm production was improved at the 3 ages
• at 24 and 32 weeks age: +55% and +38%
• at 40 weeks age: multiplied by more than 3

•
CAROPHYLL® Red 10% supplementation had a beneficial effect on:
• Percentages of semen donors
• Semen volume
• Sperm viability
•
These positive effects of CAROPHYLL® Red 10% supplementation on
fertility parameters were higher in aging males (40 weeks of age), a
period revealed as featuring a progressive decline of antioxidant
defenses in earlier broiler breeder observations
