This document provides an overview of recently adopted nutrition concepts in North America presented by R. Dean Boyd. Key points include:
1) Feeding essential fatty acids like linoleic acid and alpha-linolenic acid to lactating sows to improve reproductive efficiency under heat stress.
2) The increased adoption of net energy systems over metabolizable energy in North America to improve diet formulation accuracy.
3) Strategies to improve pig viability like feeding xylanase and controlling lipid peroxidation in diets, which can impact health and performance.
4) Expanded use of synthetic amino acids in swine diets including newer additions like L-histidine and L-arginine.
Can proteases play a role in enteric health- Langhout, P. Presentation for Workshop 4, at the Feed Proteases and enzyme presentation, The Netherlands, 2014
The document discusses optimizing protein digestion in poultry through the use of exogenous proteases, noting that both endogenous proteins secreted by the bird and undigested dietary proteins leave the ileum undigested. It examines factors that influence protein digestion like diet composition and quality, and endogenous protein sources and recovery. Models are presented that can help predict how diet inputs like crude protein level and amino acid ratios influence the efficacy of adding an exogenous protease supplement to improve protein digestion and bird performance.
The document discusses the impact of bypass nutrients on the immune system. It notes that the immune system prioritizes nutrients and an optimal response eliminates pathogens with minimal intensity and duration. Good nutrition through balanced diets improves disease resistance by supporting the immune system and counteracting stress. Certain bypass proteins and fats can enhance immunity when included in livestock diets at moderate levels. Condensed tannins from plants may also act as natural dewormers and support the immune response in fighting gastrointestinal parasites. Feeding a scientifically formulated calf starter incorporating bypass nutrients was shown to improve weight gain and immune markers while reducing parasitic load compared to a traditional ration.
This document discusses key factors to consider when selecting feed enzyme products for poultry production. It outlines three main classes of enzymes used in poultry feeds - phytases, carbohydrases, and proteases. When choosing an enzyme product, it is important to evaluate whether the enzyme will improve digestibility of the specific feed formulation, is thermostable for pelleting conditions, and is compatible with other enzymes. The document also stresses selecting enzymes that have proven mechanisms of action and are produced under quality manufacturing standards.

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.

Dr. Young-Dal Jang - Evaluating Nutrient Uplift When Feeding XylanaseJohn Blue
Young-Dal Jang presented research on the effects of xylanase and phytase supplementation in high fiber diets for pigs. The research included two experiments:
1. Supplementing xylanase at increasing levels to diets containing phytase, which improved fiber digestibility and energy utilization but did not affect other nutrient digestibility.
2. Supplementing both xylanase and graded levels of phytase, which showed interactions between the enzymes and improved growth performance and nutrient digestibility compared to diets without supplementation. The results indicate xylanase can improve the action of phytase in high fiber diets.

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.
The document discusses the role of enzymes in poultry nutrition. It describes how most poultry diets contain maize and soybeans which contain phytate and non-starch polysaccharides that can negatively impact nutrient absorption. The use of enzymes can help address this by breaking down these anti-nutrients. Specifically, exogenous enzymes are described that help supplement endogenous enzymes or aid in breaking down substances like beta-glucans and phytate that poultry cannot digest on their own. Research shows that enzymes can improve growth performance, nutrient utilization, and bone mineralization in poultry. Higher enzyme doses beyond 500 FTU/kg are also beneficial.
This document discusses various implants and feed additives used in livestock production. It describes different types of implants including estrogen-based, progesterone, androgen-based, and combination implants. It explains their modes of action in increasing average daily gain, feed efficiency, and carcass characteristics. The document also outlines categories of feed additives like ionophores, antibiotics, beta-agonists, buffers, and natural additives. It notes the benefits of ionophores in improving energy and protein metabolism in ruminants. In conclusion, the document emphasizes following label directions and doing research when using implants and additives.
This document summarizes research on the use of organic acids in animal nutrition. It discusses how organic acids have gained importance in feed industry following the ban of antibiotic growth promoters. Short chain organic acids can have antimicrobial properties. Research shows that organic acids can improve animal performance by reducing pathogenic bacteria counts, increasing nutrient digestibility, and improving gut health. Studies demonstrate that supplementing animal feed with organic acids like formic acid, fumaric acid, and butyric acid can positively impact growth performance, gut morphology, and nutrient utilization in poultry and pigs.
This document discusses probiotics, including their history, definition, commonly used strains, properties, established health effects, mechanisms of action, advantages, effects in livestock, synergistic use with prebiotics, and the market size. Probiotics are live microorganisms that, when consumed in adequate amounts, confer health benefits. Commonly used probiotic strains include Lactobacillus and Bifidobacterium. Probiotics can help treat conditions like antibiotic-associated diarrhea, cancer, and high cholesterol, and provide benefits to livestock. Prebiotics feed beneficial bacteria to create synbiotic combinations with probiotics. The global probiotics market was estimated at $15.9 billion in 2008 and is projected to reach $

1. Common probiotic strains used are various Lactobacillus and Bifidobacterium species.
2. Probiotics must be live microorganisms, survive the GI tract, and exert beneficial effects on the host.
3. Benefits of probiotics include antimicrobial properties, reducing cholesterol, and stimulating the immune system.
4. Prebiotics are non-digestible foods that stimulate the growth of probiotic bacteria in the colon. Common prebiotics include fructooligosaccharides and galactooligosaccharides.
The document discusses various feed additives used in the poultry industry, including alternatives to antibiotics. It notes that while antibiotics were widely used to improve growth and health, alternatives are now being explored due to concerns about antibiotic resistance. These alternatives include enzymes, antioxidants, acidifiers, probiotics, and prebiotics, which can improve digestion, gut health, and immunity without antibiotics. The industry is researching new enzymes and additives that provide nutritional and health benefits for poultry.
Probiotics and prebiotics are live microorganisms and non-digestible foods that provide health benefits when consumed. Probiotics are live microorganisms that help establish and maintain a healthy gut microbiome, while prebiotics are non-digestible foods that act as fertilizers to encourage the growth of good bacteria. The document discusses the differences between probiotics and prebiotics, examples of each, their mechanisms of action in the body, ideal properties of probiotic strains, and their applications and benefits in aquaculture.
The document discusses various types of feed additives that are administered to animals and poultry to enhance nutrient effectiveness and digestion. It describes antibiotics, probiotics, prebiotics, antioxidants, emulsifiers, binders, organic acids, enzymes, phytogenics, and other additives. For each type, it provides examples and explains their modes of action, such as reducing pathogens, increasing nutrient absorption, and improving gut health. The document also notes that overuse of antibiotics as growth promoters can lead to antibiotic resistance.
Probiotics are useful microorganisms to fight against pathogenic bacteria in human gut . Commercially bacteria and fungus are being used as probiotic organisms
Probiotics and prebiotics are live microorganisms and non-digestible foods respectively that provide health benefits. Probiotics include Lactobacillus, Bifidobacterium, and Saccharomyces that help maintain a healthy gut microbiome.

This document discusses potential future steps to reduce antibiotic usage in commercial beef production. It outlines why antibiotic reduction is needed due to increasing antibiotic resistance. It then discusses various strategies that can be used to reduce antibiotic usage, including procuring healthier cattle, pre-vaccinating and backgrounding cattle before feedlot entry, improving stockmanship and acclimation practices, more precise disease diagnosis, and alternatives to in-feed antibiotics like direct fed microbials. The overall goal is to reduce sickness in feedlots and thereby reduce the need for antibiotic treatments.
10. Feedworks-Rumen function (and dysfunction).pptx2damcreative
This document summarizes rumen function and factors that can lead to rumen dysfunction. Proper rumen function requires rumination to break down feed particles and maintain pH, as well as motility to mix contents and absorb fermentation acids. A key regulator of rumen pH is the balance between production and absorption/passage of fermentation acids. Low rumen pH can decrease fiber digestion and passage rates. Risk factors for low pH include low rumen fill, highly fermentable rations, and feeding grains separately from forages. Low pH can damage the rumen epithelium and increase risks of acidosis.
1. Trace minerals play an important role in modulating inflammation and reproductive organs but have an indirect effect on reproductive performance.
2. While cows are generally not deficient in minerals, optimizing trace mineral nutrition can help get cows into a high fertility cycle and keep them there by reducing inflammation and supporting tissue health.
3. Overfeeding copper poses the greatest risk, so minerals need to be carefully balanced to support reproduction without causing toxicity issues.

This document provides information on calf health from a presentation given by Dr. Curtis Harms at the Feedworks Conference in 2022. It discusses where calves fit as a priority on dairies, problems commonly seen, and considerations that can help improve calf health and future profitability. The document notes that a calf's future depends more on the dairy it was born on than its dam, and that health challenges are often more due to two-legged (human) problems than four-legged (disease) problems. It emphasizes cleanliness, colostrum, consistency, monitoring health objectively, and not believing calves can solely "catch up" in later stages.

This presentation discusses feeding sheep and cattle. It addresses common diet questions and covers nutrient specifications, ingredient selection, diet formulation, feed manufacturing methods, and feeding management strategies. The key topics include the differences between starter and finisher diets, factors that affect feed intake like feed sorting and particle size, the benefits of total mixed rations over component feeding, and the importance of bunk management and rumination for digestive health and production.
Icelandic Lithothamnion (Acid Buf) is a unique calcium source derived from red marine algae with distinct physical and compositional properties compared to other lithothamnion sources and limestone. Laboratory experiments show Acid Buf has superior buffering capacity and ability to maintain rumen pH. Recent research found Acid Buf improved feed efficiency, fat yield, and reduced inflammation in transition cows. Its anti-inflammatory effects are believed to contribute to performance benefits observed in multiple studies.
1. 2022 Baumgard Australia LPS and Fertility.pptx2damcreative
This document summarizes research on inflammation during the transition period in dairy cows and its impacts. It discusses how inflammation occurs in all cows during this time, and how the magnitude differs. Inflammation is found to precede clinical diseases like mastitis and metritis. The document hypothesizes that inflammation causes reduced feed intake, leading to increased NEFA and ketones. It also suggests inflammation contributes to hypocalcemia and impaired reproduction. Rather than seeing high NEFA and ketones as direct causes of issues, the document proposes they are symptoms of prior immune stimulation and inflammation.
This document discusses Nedap's livestock management software and equipment. It describes their electronic feeding stations that measure daily feed intake and monitor gestating sow weights. It also discusses their farrowing feeding system that provides exact feeding for breeding and is easy to use via mobile devices. Additionally, it summarizes Nedap's pig performance testing system which measures growth performance in real time and exports data on animal numbers, visits, durations, weights and feed intake. The system allows for sorting pigs by weight to different feed types and monitoring individual weights and visits to forecast target weights.
This document discusses concepts in vitamin D nutrition for poultry and swine production. It summarizes research showing that older birds have impaired conversion of vitamin D, leading to decreased calcium absorption and poorer egg quality. Supplementation with the active form of vitamin D, 1,25-dihydroxycholecalciferol, can help support calcium and phosphorus metabolism. The product Panbonis, which contains the plant Solanum glaucophyllum that naturally produces 1,25-dihydroxycholecalciferol, was shown to improve performance metrics in layers and reduce feed costs. The document also discusses how vitamin D can support reproduction in swine by influencing the uterus, muscle contraction, and implantation.
8.Closed Conversation - Diamond V Monogastric Update Feedworks_2022.pptx2damcreative
This document provides information about a presentation given by Dr. Curtis Harms at the Feedworks Conference on September 14, 2022. It discusses the benefits of postbiotics, specifically Diamond V's XPC product, on poultry, swine, and animal performance. Some key findings presented include improved egg production, feed efficiency, mortality and other performance metrics in layers and broilers fed XPC. Benefits were also shown in breeder hen reproduction and progeny performance. Research on sows demonstrated increased litter weaning weights and fewer piglet deaths. The document concludes with results from a Brazil study showing improved feed conversion in grow/finish pigs fed XPC Ultra.

6. 220916 HA ZPM in the monogastric space ver3.pptx2damcreative
This document discusses the use of performance minerals to improve pig and poultry performance. It provides information on several studies that show minerals like zinc, manganese, and copper from Zinpro sources like Availa-Sow can help increase sow longevity and litter performance, reduce lameness in sows, and increase weaning weights in piglets. The document also discusses benefits of Zinpro minerals for poultry breeders and layers in improving eggshell quality, hatchability, and chick weights. Finally, it summarizes research showing Zinpro minerals can improve broiler performance and reduce Salmonella levels.
5. Twin Water Copper benefits CoRouge.pptx2damcreative
This document discusses the benefits of high levels of copper in pig and poultry diets. It summarizes research showing that 75-250ppm of copper promotes growth and feed efficiency. The mode of action includes increasing growth hormone, lipase activity, and decreasing GI tract bacteria. A meta-analysis found maximum broiler growth at 158ppm copper and best feed conversion at 217ppm copper. Copper reduces bacteria populations through altering bacterial proteins and enzymes. It also reduces activity of the BSH enzyme, improving fat digestibility. Studies show monovalent copper from CoRouge improves performance with reduced toxicity risks and copper in excrement compared to other copper sources.
The document discusses creatine metabolism and supplementation. It summarizes that creatine plays a critical role in cellular energy balance by buffering ATP levels. The creatine-phosphocreatine system works to counter ATP shortage and formation of free radicals. Supplementing animals' diets with creatine (GAA) leads to increased performance outcomes like breast meat yield, body weight gain, and improved feed conversion ratio. Studies in poultry, pigs, and their offspring show supplementation can spare dietary energy and amino acids while maintaining or improving production metrics.
The document discusses achieving inorganic phosphorus-free broiler production through optimized phytase and diet formulations. It outlines several approaches: using a highly efficient phytase to breakdown most phytate, stimulating gizzard development, sufficient phytate phosphorus levels from plant ingredients, optimized calcium levels based on limestone solubility, and phase-specific phytase dosing strategies. Trials with Ross 308 broilers were set up with varying phytate phosphorus levels in diets containing corn, wheat, soybean, rice, wheat bran, and rapeseed/sunflower meals. Phytase and xylanase were included at specified levels while meeting minimum metabolizable energy and nutrient specifications compared to breeder recommendations.
This document summarizes the challenges facing the US pig industry according to Kyle Coble of JBS Live Pork. The three main challenges are labor shortages, disease pressure including African Swine Fever, and increasing demands for environmental sustainability. Regarding labor, unemployment is low while wages are increasing. To address this, JBS uses strategies like developing hourly employees, partnering with training programs, and exploring automation. Disease prevention relies on initiatives like the Swine Health Improvement Plan. Carbon neutral goals will impact the industry, requiring approaches like evaluating life cycle assessments of inputs. Overall the industry must embrace changes and continue innovating to succeed.

2. The Aim
To offer “cost effective alternatives” to antibiotics
to limit resistance so they are highly effective
when required
… and keep the supermarkets happy
3. Aims to promote good gut health
• To create a strong and stable beneficial microflora in the GI tract
• Reduce rapid diet changes
• Raw ingredients and additives that increase Butyrate production
• Additives that reduce gut inflammation
• And dietary means to improve but not stimulate the immune
response
4. So what are the “alternatives”?
• Acids (short and medium chain fatty acids)
• Probiotics (single to multi-strained bacillus)
• Prebiotics (yeast cell/metabolites, inulin, β glucan)
• Essential oils
• Phytobiotics
• Algae extracts (Fucoidan, Laminarin)
• Betaine
• Spray Dried Plasma (weaer pigs and broiler starters)
• Zinc Oxide/HiZox
• Toxin binders/deactivators
11. Acids – the good and the bad
• Short chain fatty acids mostly effective against gram negative
bacteria (eg Salmonella and E. coli)
• Medium chain acids (C6-C12), particularly Lauric Acid, against
all bacteria and some viruses, but slightly better on gram
positive.
12. Which is the best acid?
• In vitro work showed short chain (fatty) acids could be ranked
as follows: formic > propionic > lactic. Diebold and Eidesburger 2006
• Medium chain acids carry the most anti bacterial effect against
salmonella than short chain acids. Van Immerseel et al (2006)
• Short chain acids such as butyric and formic have the capacity
to reduce the efficacy of salmonella to invade epithelial cells. Van
Immerseel et al (2006) Ricke, 2002
13. Acids ain’t Acids
• Remember it’s the R-COO- NOT
the H+ ion for longer term effects
• Dietary and Gut Bicarbonate nullify
most H+

23. Is there long term tolerance to acids by pathogens?
• Yes there is reasonable evidence (S. Ricke, 2002, Foster, 1995; Leyer
and Johnson, 1992; Arnold et al, 2001 and Kwon et al 2002)
• At least use regular changes/shuttles in the acid
program.
• Best acids are Protected Butyrate and medium chain
fatty acids/Lauric acid…. But
………..…. We need an alternative to acids too!!
24. Formaldehyde has a high level of broad antibacterial activity. It acts directly on forming
irreversible cross-linking of functional proteins within the bacterial cell.
Most cost efficient effective chemical treatment against salmonella for stockfeed (Davis
and Wray, 1995)
In commercial settings, formaldehyde treatment is generally combined with technologies
that offer cross protection such as organic acids either straight or embedded in slow-
release carriers.
An extensive study by JJ Carrique-Mas et al, 2006, compared four commercial
technologies for the reduction of artificially contaminated meals and finished feeds with
Salmonella. Treatment with formaldehyde appeared to be the only effective method,
Formaldehyde
25. Prebiotics
• Functional carbohydrate that promote beneficial
bacteria…. Competitive Exclusion
• Beneficial fibre/NSP
– Insoluble arabinoxylan (wheat, wheat bran/millmix), beta-
glucan (barley and oats)
– Enhanced by Xylanase and beta glucanase enzymes
• Prebiotic like additives (Yeast metabolites, inulin, mixed linkage beta
glucan from cereal, yeast or algae, xylo-oligosaccarides etc.)
26. The amount and type of functional
carbohydrate/prebiotic and will depend on type

intestinal epithelium, and help control inflammatory and malignant
diseases of the intestine
Possemiers et al (2013) J Ag Food Chem
Butyrate Production
28. Butyrate (not Butyric acid):
The Wonder Molecule!?
• Small chain volatile fatty acid (pH 4.82) BUT!
• Primary source of energy (ATP) in the colon
• Increases growth of “normal” mucosa cells
• Reduces inflammation
• Reduces leaky gut
• Provides innate immunity
• Inhibits growth of pathogens
• Reduces cancer
30. The beneficial bugs
• Butyrate producers
– Clostridium (now Blautia) coccoides and Clostridium leptum
– Faecalibactrium pranusnitzii
• Acetate producers – the ↑ bacteria convert acetate to Butyrate
– Bifidobacteria and Akkermansia (mucin feeders)
31. Minimise fermentable protein !!
• Increased levels of ammonia, hydrogen sulphide and phenols, polyamines (eg
cadaverine)
• These are toxic and damage gut lining → leaky gut
• Undigested protein or excessive amounts produce pathogens (E coli, pathogenic Clostridia
and salmonella)
• Decreases Butyrate!
• Produces inflammation of the gut
• Increase cytokine production which reduce feed intake
32. Manno Oligosacharides (MOS) or Refined
Fraccionated Carbohydrates (RFCs)
MOS or RFCs is a relatively new technology available to the feed industry. These molecules contain certain
physicochemical structures that allow for the agglutination/binding of type-1 fimbrie (hairs) of Salmonella and other
gram negative species.
A study by Borowsky et al 2009, demonstrated that out of 108 salmonella strains, 74% demonstrated strong
agglutination to MOS in vitro.
In vivo studies have also demonstrated the efficacy of these molecules to reduce Salmonella caecal counts in chickens
when added as a feed supplement in the diet (Fernandez et al 2000; Spring et al 2000; Spencer 1997)
34. Xylanase decreases mortalities in pigs
• Xylanase creates prebiotics from fibre/NSP breakdown
• Boyd et al 2015;
– High levels of Xylanase activity (6000 units/kg) reduced mortalities by 40% in a
typical USA diet
• Beckers, 2016
– Lower levels of Xylanase 1500 units/kg decreased mortalities by 27.9% in
wheat/soy/DDGS
– 1500 to 3000 units/kg xylanase decreased morbidities/removals by 20.1 and
50.1% respectively.
35. Probiotics
• The best probiotic is lactobacillus based, BUT this are unstable and
have poor shelf life (Stanley et al 2016)
• The majority of Probiotics are Bacillus
• Bacillus spores that are poor colonisers so must be offered all the
time
• The Bacillus spores are heat stable and long shelf life… so it’s a
compromise!
36. Early colonisation
Dana Stanley
• Life time microflora population strongly influenced by exposure in
the first 2 days
• Feeding a live lactobacillus probiotic in the first day significant long
term benefit
• Potential for hatchery gels
