The document discusses the role of enzymes in poultry nutrition. It notes that the poultry industry in India has seen 10-12% growth in broilers and 5-7% growth in layers. Enzyme feed additives can improve production performance by increasing nutrient utilization and preventing the effects of anti-nutritional factors like phytate. Phytate binds with minerals and other nutrients, reducing their availability, but phytase enzymes can break down phytate and release those bound nutrients. The addition of phytase supplements to poultry feed has been shown to improve growth performance, feed efficiency, egg production and nutrient utilization.
The document discusses phytate (myo-inositol hexaphosphate) which is an anti-nutritional factor found in all plant-based feed sources. Poultry have insufficient ability to break down and utilize the phosphorus in phytate. Phytase is an enzyme that can hydrolyze phytate, reducing its negative effects and improving phosphorus absorption and poultry growth performance. The document outlines sources of phytase including plants and microbes like fungi and bacteria, as well as units used to measure phytase activity.
This document discusses the use of exogenous enzymes in poultry nutrition as an alternative to antibiotics. It provides background on how antibiotics were commonly used but are now banned. Exogenous enzymes are one potential alternative as they can help break down non-starch polysaccharides in feed ingredients like wheat and barley to improve digestibility. The document outlines different types of enzymes and their sources and effects. It summarizes studies looking at how exogenous enzymes can reduce the size of digestive organs and positively impact gut morphology.
This document discusses amino acids in broilers and layers. It provides information on essential, non-essential, and semi-essential amino acids. The first limiting amino acid in poultry diets is typically methionine, while the second limiting is lysine. Studies have shown that protein levels can be reduced in broiler and layer diets by balancing amino acids, especially lysine and methionine levels. Reducing protein to around 15-16% in broilers and 14% in layers is possible with a minimum of 0.7% lysine supplementation. Properly balancing amino acids allows for more efficient feed utilization and production performance with lower dietary protein levels.
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 enzymes used in poultry and ruminant nutrition. It describes how enzymes are proteins that catalyze reactions without being consumed in the process. Exogenous enzymes from sources like bacteria, fungi and yeasts are added to animal feed to help break down nutrients. Specific enzymes discussed include beta-glucanases, xylanases, phytases, amylases and proteases. These enzymes help improve nutrient digestion and absorption, increase growth performance, and reduce nutrient excretion in waste. The document provides details on the chemical nature, modes of action and typical doses of various enzymes used in animal feed supplementation.
Feed additives are non-nutritive products used in small amounts to improve feed quality, nutrient utilization, and growth performance in poultry. Common feed additives include growth promoters, toxin binders, antioxidants, electrolytes, emulsifiers, feed preservatives, pellet binders, and coccidiostates. Growth promoters can be antibiotic growth promoters, natural growth promoters like prebiotics, probiotics, synbiotics, yeasts, organic acids, herbal supplements, enzymes, and vitamins and minerals.
Rumen bypass protein, also called rumen escape or undegradable protein, refers to the portion of protein in animal feed that is not broken down or digested in the rumen by microbes. Rumen bypass or "protected" fats are dry fats processed to be easily handled and mixed into animal feeds that are insoluble at rumen body temperature and thus bypass digestion in the rumen. Protected nutrient technology protects feed nutrients like protein and fat from degradation in the rumen so they can bypass to the lower gastrointestinal tract and provide amino acids and other nutrients to animals.
This document discusses proteases and their role in digestion in poultry. It begins by explaining that animals must obtain some amino acids from their diet as they lack the necessary enzymes to synthesize them. It then describes how ingested proteins are broken down through digestion involving acid and protease enzymes. The document provides classifications and examples of different types of proteases. It discusses how proteases break down proteins, fats, and carbohydrates at different pH levels along the gastrointestinal tract. The document also notes some anti-nutritional factors found in various feed ingredients and how proteases can help degrade them to improve digestibility.

Amino acids are organic compounds that serve as building blocks of protein. There are over 700 amino acids found in nature but only 20 are used in protein synthesis. Amino acids are classified as essential, non-essential, and semi-essential depending on an animal's ability to synthesize them. Most amino acids exist in two isomeric forms (L and D) but only the L-form is used in protein synthesis. Imbalances or deficiencies in amino acids can negatively impact animal health and performance. Amino acids interact with each other and have many important functions including protein synthesis, gene expression, hormone production, nutrient metabolism, immune function, and more.
Manipulations of rumen function that can augment livestock productivity are;
Correction of concentrate to roughage ratio
Feed bypass or escaped nutrients
Defaunation of rumen
Use of yeast as probiotics
Use of anaerobic fungi
Use of other feed additives
This document discusses different types of enzymes that can be added to animal feeds, including poultry feeds, to improve digestibility and nutrient availability. It describes three main classes of enzymes - phytases, carbohydrases, and proteases. Phytases help release phosphorus from plant ingredients. Carbohydrases like amylase and xylanase improve the digestibility of carbohydrates. Proteases aid in protein digestion. The addition of these enzymes can increase available energy from feeds by 3-5% and improve growth performance in poultry.

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.
Factors influencing the nutrient requirements in poultrySunil Yadav
This Presentation will help you to understand the various factors that are responsible for the nutrient requirement of poultry. While formulating feed for any classes of poultry we should consider all these factors for a better outcome from the bird.
This document discusses various types of feed additives used to improve animal growth and feed efficiency. It describes common feed additives like antibiotics, hormones, probiotics, prebiotics, enzymes, acids, antioxidants, and flavors. It provides examples of specific additives used and explains their mechanisms of action, including improving nutrient digestibility and availability, modifying gut microflora, enhancing immune response, and altering animal metabolism and growth pathways. The document also notes some potential consequences if certain additives like antibiotics are banned.
This document discusses organic acids in poultry nutrition. It defines organic acids as carboxylic acids containing a carboxyl group that is the source of a donatable hydrogen ion. Organic acids are classified based on carbon chain length as short chain (C1-C6), medium chain (C7-C10), or long chain (C11+). Short chain fatty acids have antimicrobial properties and are the most commonly used in poultry. Organic acids reduce gut pH and disrupt bacterial cell membranes and DNA, inhibiting microbial growth. Their effectiveness depends on concentration in the gastrointestinal tract, with more impact higher in the gut where dissociation is lower. Common organic acids used in poultry include formic,
feed aditives, their classification, mode of action & use in ruminantsDr. Waqas Nawaz
Feed additives are non-nutritive products added to animal feed to improve feed quality, animal performance, health, and product quality. They are classified into five groups - technological, sensory, nutritional, zootechnical, and coccidiostats/histomonostats. Common feed additives include enzymes, antibiotics, ionophores, probiotics, oligosaccharides, and yeast cultures. Their modes of action include improving nutrient digestibility and availability, stabilizing rumen pH, and altering rumen microbial activity. Common uses of feed additives are to increase milk and meat production, improve feed efficiency, and reduce heat stress.
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.
Some enzymes work against anti-nutritional factors (ANF), which are produced by plants, in order to obtain more nutrients from plants for increased animal nutrition.
The correct enzyme (or combination of enzymes) need to be used for the specific target. This depends on the plant cell wall structure. For example, the cell walls of the endosperm of corn is comprised mainly of insloluble arabinoxylans, which means that only xylanases are able to degrade this wall to increase the energy value of corn based diets.

Organic, functional, designer & SPF feed production
The market for organic poultry products is strong
and growing. Integrating either small-scale or
large-scale production into your farm system can
be both enjoyable and lucrative.
Animal feed accounts for 60-70% of livestock and poultry production costs. Supplementing feed with enzymes can help producers save costs by enabling animals to produce more meat faster and cheaper. There are several types of enzymes that play important roles in animal feed digestion. Proteases break down proteins, carbohydrases improve carbohydrate digestibility, and phytases allow animals to access phosphorus stored in plant feeds. Using enzymes can boost feed efficiency, lower feed costs, and reduce environmental impacts.
This document summarizes key aspects of managing the transition period for high-yielding dairy cows. The transition period is 4 weeks before and after calving and is a time of increased health risks. Feeding a balanced transition diet is important to reduce risks of diseases like milk fever and ketosis. The transition diet should gradually increase energy and protein while decreasing fiber to support intake and metabolism without disrupting the rumen. Minerals like calcium, phosphorus, and magnesium and the dietary cation-anion difference must be carefully managed to prevent milk fever. Commercial transition supplements can help achieve these nutrient balances and support a smooth transition to lactation.
Role of toxin binder, acidifier and mold inhibitor in feed formulation. types...Bimochan Poudel
This document discusses the roles of toxin binders, acidifiers, and mold inhibitors in animal feed formulation. It describes the types and effects of various mycotoxins on large animals and poultry. It then explains how toxin binders work to prevent mycotoxins from entering the bloodstream by trapping them. The main types of toxin binders discussed are silicate products, inorganic polymers, organic polymers, and carbon products. It also discusses the roles of acidifiers in inhibiting mold and harmful bacteria while improving beneficial bacteria. Finally, it covers the roles of mold inhibitors in minimizing and preventing mold growth and contamination in feed.
- Loss of livestock due to mycotoxins produced by fungi like Aspergillus is a major issue. Aflatoxins, particularly aflatoxin B1, are the most common mycotoxins found in animal feed.
- Strategies to reduce the impact of mycotoxins include using mycotoxin binders in feed to decrease the bioavailability of mycotoxins by binding to them in the digestive tract. Common binders used include various types of clays, yeast cell walls, and activated charcoal.
- The ideal mycotoxin binder adsorbs a wide range of mycotoxins, has a low inclusion rate in feed,
Phytase is an enzyme that helps non-ruminant animals like poultry and swine break down and absorb phosphorus from grains. It allows these animals to utilize phosphorus from phytate in grains, reducing the need for supplemental phosphorus in their diets. Phytase is produced by microbes like bacteria and fungi. It works by hydrolyzing phytate, making phosphorus more available to the animal. The use of phytase supplements in animal feed lowers feed costs and decreases phosphorus pollution by allowing animals to excrete less phosphorus.
This document discusses precision feeding in livestock. It begins by explaining how precision feeding aims to meet the exact nutrient requirements of individual animals through determining the right amount, composition, and timing of feed. This is achieved through tools like precise nutrient analysis, ration formulation based on digestible nutrients, use of additives, and appropriate feeding management methods like phase and split-sex feeding. Phase feeding in particular is described as improving performance and economic return while reducing nutrient excretion compared to single-diet feeding programs. The overall goal of precision feeding is optimizing production efficiency while minimizing environmental impact.
The liver is the central laboratory of a chicken’s body. It is essential that this organ is kept in an excellent condition in order to maintain a healthy bird. Understanding the metabolic function and causes of disruptions in liver functions helps us to provide the birds with the right feed and health treatment.
When we cut open the body of a chicken, the first organ that is most likely revealed is the liver. The message is clear. Nature wants us to examine the liver carefully before
proceeding to the other organs.The liver contains great functional reserve capacity, which is very important in domestic animals subjected to high production requirements. This organ adapts easily to different conditions by increasing the intensity of its functions.
Particularly in broilers, the liver has to cope with many challenges, including
high energy level feed, the addition of chemotherapeutics, coccidiostats
and others, whose desired metabolites must be maintained in equilibrium by hepatic homeostasis.Incidental treatments with highly hepatotoxic and nephrotoxic antibiotics
or sulfonamides pose serious risks and cause situations of difficult prognosis during a 40-45 day period in which the body acquires satisfactory muscular mass. What is the function of the liver and what might be the cause of malfunctioning?

Manure Evaluation: Key To Nutrition And Herd Health.pptAzerbaijan
This document discusses evaluating dairy cow manure as a way to understand rumen function and digestion. Manure evaluation can indicate whether changes need to be made to the cow's diet formulation. Fermentation in the rumen and hindgut produces organic acids, microbial protein, and gases. Insufficient fiber intake can lead to acidosis and poor digestion seen in manure. Proper particle size and effective fiber are important for rumination, buffering, and manure characteristics. Certain feed ingredients or moldy feeds may cause diarrhea visible in manure.

The document discusses soybean meal and its use as an animal feed. It provides details on the types and processing of soybean meal, its nutritional composition, and use in feeding various animals including ruminants, poultry, pigs, fish, dogs, horses and others. It notes soybean meal is high in protein and amino acids but also contains some anti-nutritional factors. The document concludes with discussing the advantages and disadvantages of soybean meal for animal feeding.
There are two main sources of alternative protein foods derived from non-animal sources: plants and microorganisms. Soybeans are the most common plant-based protein and are used to make foods like tofu, soy milk, soy yogurt, and textured vegetable protein (TVP). TVP is made from defatted soybean flour and can be used as a cheaper meat substitute or extender. Mycoprotein is produced from fungi cells and is used to make products sold under the brand name Quorn as a meat substitute. Both soy proteins and mycoprotein provide nutrition similar to meat but without saturated fat.
This document discusses precision feeding in dairy cattle. It defines precision feeding as meeting nutrient requirements with maximum precision to ensure efficient and safe production while minimizing environmental pollution. Precision feeding involves phase feeding, with different dietary formulations for early, mid, and late lactation. Key aspects of precision feeding discussed include improving nitrogen use efficiency, reducing methane emissions, and using additives to maintain rumen health and increase nutrient utilization.
This study compared the efficacy of four phytase products - PHY1 from Citrobacter braakii, PHY2 from E.coli, PHY3 from E.coli, and PHY4 from Peniophora lycii - on growth performance, apparent ileal phosphorus digestibility (AIDP), and bone mineralization in broiler chickens. PHY1 and PHY3 resulted in better growth performance compared to PHY2 and PHY4, and performed equally to the positive control diet. All phytase treatments resulted in similar effects in terms of bone mineralization and AIDP.
1) The document discusses the nutritional profiles of various foods that are important components of a balanced Indian diet, including cereals, pulses, vegetables, fruits, nuts, oils, animal foods, and beverages.
2) Cereals like rice, wheat, and maize are good sources of carbohydrates but deficient in some amino acids. Combining cereals with pulses provides a more complete protein profile.
3) Pulses are rich in protein, minerals, and B vitamins but low in vitamins A and C. Soybeans specifically are very high in protein.
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.
Disappearance of infused phytate from the large intestine of dairy heifersPartha Ray
This study investigated the degradation of phytate (a form of phosphorus) in the large intestine of dairy heifers. Eight heifers with ruminal and ileal cannulas were fed a low-phosphorus diet and infused with varying amounts of phytate into the ileum. Feces were collected and analyzed for phytate, inorganic phosphorus, and total phosphorus. Results showed that phytate was degraded but not completely in the large intestine. Fecal phosphorus excretion increased with higher amounts of infused phytate. Approximately 44% of phosphorus from dietary sources flowing to the ileum was absorbed in the large intestine, compared to 25% from infused pure phytate

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.
Wheat and its byproducts - Health benefits and application in food industry Shweta Priyadarshini
Wheat is a major grain that provides many nutrients. It has three main parts - the bran, germ, and endosperm. The bran provides fiber, while the endosperm contains starch and proteins. The germ is high in fat. Wheat foods provide various vitamins and minerals. Consumption of wheat bran and germ is linked to reduced disease risk due to antioxidant compounds. Wheat can be processed into various foods like breads, pastas, and cereals. Byproducts include bran, shorts, middlings and wheat germ, which are used in livestock feed or to fortify foods.

- The document discusses advances in understanding how enzyme substrates interact in animal guts and how this can be applied to improve animal nutrition and performance.
- Enzymes can increase the digestion of nutrients like starch, fiber, and protein by hydrolyzing substrates. This makes more nutrients available for absorption in the gut and can ultimately improve growth and feed efficiency.
- The gut microbiome also plays a key role by fermenting undigested fibers to produce energy for the animal in the form of short-chain fatty acids. Enzymes may interact with the microbiome to further increase nutrient availability.
This study investigated the effects of a phytase enzyme from C. braakii on phosphorus digestibility and phytate degradation in soybean meal, rapeseed meal, corn, and wheat for broiler chickens. Ten male broilers per treatment were fed one of nine diets, including a nitrogen-free synthetic diet and semi-purified diets with or without 1000 U/kg of phytase added, from days 20-24. True ileal phosphorus digestibility and phytate phosphorus disappearance were measured. The phytase significantly improved the hydrolysis of phytate phosphorus and total phosphorus digestibility of soybean meal, rapeseed meal, wheat, and corn.

proteolytic enzymes and fat
18. Mode of Action of Phytate on Minerals
Phytate has strong chelating potential
Forms insoluble salts with di or trivalent cations
It binds strongly in the following order – Cu++, Zn++,
Co++, Mn++, Fe+++, Ca++( Vohra, 1965)
Phytate in feed makes more requirement of inorganic
minerals

29. Nutritional Benefit of Phytase
Protein and amino acids availability
Kornegay (1999) reported that phytase in corn-soyabean
diet enhanced protein utilisation in broilers
Namkung and Leeson (1999) found that phytase in corn-
soyabean diet increased the digestibility of Valine,
Isoleucine (P<0.05) and total animo acids
Ravindran et al (2001) reported that graded level of
phytase in lysine-deficient broiler diet had siginificant
effect on digestibility of all amino acids.
30. ……Nutritional Benefit of Phytase
Bio- availability of Phosphorus
Simons et al (1990) reported that phytase in low
phosphorus corn-soyabean diet increased the bio-
availability of phophorus to over 60 percent and decreased
the phosphorus in droppins by 50 percent
Quantity of phytate phosphorus release by microbial
phytase depends on its concentration, sources , calcium
content and phytate content of feed – Kornegay et al
(1996), Ravindran et al (1995) and Yi et al (1994)
31. …….Nutritional Benefit of Phytase
Bio- availability of other minerals
Phytic acid form complexes with cations which are
released upon dephosphorylation by phytase
Calcium, copper, zinc, Manganese and magnesiums are
released from chelates
Simon et al (1990), Yi et al ( 1996) and Sebastian et al
(1996)
32. …..Nutritional Benefit of Phytase
Egg Production
Roland and Gordon (1996) reported that phytase addition
– 300 U/Kg layer diet improved the egg production
Oloff et al (1997) observed that phytase – 500U/Kg in
phosphorus deficient corn-soya diet improved egg
production
Sukumar (1999) noted that phytase addition in low
phosphorus diet 400U/ Kg layer diet improved egg
production
33. Nutritional Benefit of Phytase
Growth performance
Several studies indicate increase in body weight gain, feed
intake and feed efficiency in broilers fed with
supplemental phytase
These effects are due to release and increased utilisation of
minerals, amino-acids, starch and fat from phytate
complex
These are conformed by Panda et al (2007), Karim
(2006), Pillai et al (2006), Singh (2006) and Selle et al

36. Environmental Pollution
Poultry manure is an important organic fertilizer
Excess phosphorus in excreta increases the soil load and
contaminates the surface water which promote
eutrophication and affect fish life
Feeding low phosphorus diet to poultry and use of phytase
reduces excretion of P 20 to 50 %
Phosphorus pollution can be controlled by formulation of
diet and use of phytase
38. Conclusion
Improve production performance – egg, meat
Improve utilization of phosphorus and other
nutrients
Lower feed cost and more farm profit
Less inorganic phosphorus supplementation needed
Decrease of phosphorus excretion by up to 50%
Environmental pollution - controlled
