Poultry nutrition - Other additives
Alternative feed additives have promising importance in broiler production due to the ban on the use of certain antibiotics. The most used antibiotic alternatives in broiler production are phytogenics, organic acids, prebiotics, probiotics, enzymes, and their derivatives. Antibiotic alternatives have been reported to increase feed intake, stimulate digestion, improve feed efficiency, increase growth performance, and reduce the incidence of diseases by modulating the intestinal microbiota and immune system, inhibiting pathogens, and improving intestinal integrity. Simply, the gut microbiota is the target to raise the health benefits and growth-promoting effects of feed additives on broilers. Therefore, naturally available feed additives are promising antibiotic alternatives for broilers.
Myths that have erroneously limited feed-grade amino acid inclusion in poultry diets have been dispelled in these proceedings by presentation of a historical perspective. In addition, recent research has been presented which has allowed for aggressive feed-grade amino acid inclusion that maintains good bird performance in diets with reduced costs and environmental impact. Namely, in the past 10 to 15 years numerous research reports have delineated threonine,...

INTRODUCTION Animal feed ingredients can provide appropriate environmentfor fungi growth and many toxic metabolites (mycotoxins) are produced by these molds. In this context, aflatoxin, a secondary toxic metabolite produced by Aspergillus flavus and Aspergillus parasiticus species, play an important role in the food chain (Pimpukdee et al , 2004). Vitamins and mycotoxin binders can be...

INTRODUCTION Animal husbandry suffers from losses due to contamination with pathogenic bacteria. Their resultant impacts in animals include lower weight gains and increased mortality. Banning the use of in-feed antibiotics (AGPs) in livestock, as has happened in the EU, placed more pressure on animal producers and feed millers. In this context, organic acids have long been used to counteract gram-negative pathogenic bacteria in animal feed; and...

INTRODUCTION The use of additives in feed for broilers is increasing every day. Enzymes are the most commonly used in this segment, they are very effective in increasing nutrient availability to broilers and guarantees the farmer a lower cost feed formulations and also an improvement in rearing conditions. Enzymes in the diet and improves the efficiency of poultry production by...

INTRODUCTION Improving the efficiency of the use of nutrients and causing a formulation to be more precise are the most effective methodologies intended to reduce losses of nutrients and improve performance parameters. According to GUENTER (2002), enzyme supplementation to animals is intended to remove or destroy anti-nutritional factors of grains and increase total digestibility of...

INTRODUCTION Major advances have occurred in poultry in the last decades, thus making it one of the most developed segments of world agriculture. Many researchers have been conducted in nutrition area in search of alternatives to enable the formulation of rations and more efficient economical, in view of that power has the largest cost in the production of broilers. The use of enzymes...

INTRODUCTION According World Health Organization (2000) antimicrobial growth promoter is antimicrobial agent used for the purpose of increasing daily weight gain or feed efficiency (feed-weight gain ratio) of food-producing animals. But the growing concern over the transmission and the proliferation of resistant bacteria via the food chain has led to a complete ban of the feed use of antibiotic growth promoters in...

Summary Dietary lipids and fatty acids are not only fundamental in determining animal performance, but also determine the eating qualities of animal products. Several methods have been used to quantify fatty acid metabolism but most involve expensive in vitro approaches that are not suitable for most laboratories. Furthermore, there is considerable variation between methods with regard to enzyme activity, which makes comparison of results between...

The biggest challenge of commercial poultry production is the availability of good quality feed on sustainable basis at stable prices. In spite of this challenge, commercial poultry production ranks among the highest source of animal protein (Iyayi, 2008). The increase in the size of the poultry industry has been faster than other food-producing animal industries. The trade volume of poultry products has also increased...

Dear Poultry Professionals and Nutritionists, I´m a student B.V.Sc.&A.H. (9th sem.) at IAAS, Nepal. My family is running a small scale layers farm (Flock Size: 1500+1500+1500=4500) in Nawalparasi District, Nepal where we are manufacturing feed by ourselves. It has really been a challenging task for us to sustain us in this business due to huge production drop during summer months and extreme rise of cost price of Soyabean Meal (Rs. 65 per...

Summary Modern-day broilers are capable of converting dietary feed ingredients into chicken-meat at ratios approaching 2:1 and constitute a more ecologically sustainable protein source for uman onsumption than alternative sources. Similarly, as discussed, chickenmeat production emits less CO2-equivalent greenhouse gases than most alternative animal protein industries. Clearly urther improvements in feed conversion ratios of broiler chickens are...

Abstract The results of 10 experiments realized from 1980 have been used to define more precisely the requirement of Lysine. Results show that the daily requirement for Lysine is related to the bird´s productivity. If the requirement is expressed in mg per gramme of egg mass produced, the requirement appears independent of the daily egg mass that is produced. From this analysis, we conclude that...

Phytate has direct anti-nutritional effects on poultry and swine, causing reductions in performance by lowering amino acid and mineral absorption and increasing endogenous losses. PHYTIN (a deposited complex of inositol hexaphosphate with potassium, magnesium and calcium) - more recognized in animal nutrition as phytate - is the major storage form of phosphorus present in seeds. ...

Introduction: Cereal grains are the main source of dietary energy in poultry nutrition and corn is by far the most widely used in broiler formulations. Any changes in the nutritional profile of the grain, will affect the overall composition of the diets (Bartov et al., 1995). During the last decade, a considerable amount of research has been conducted in order to influence the nutritional composition of corn by genetic manipulation....

The hypothesis that an increase in luminal viscosity would result in reductions in performance parameters, digesta passage rate and frequency of reverse peristalsis was tested. Chickens were fed diets containing varying quantities of guar gum, alginic acid or corn starch to influence digesta viscosity. The two guar gum treatments yielded the highest intestinal viscosities mirrored by very high feed conversion ratios, low starch digestibility and, for birds...

SUMMARY This study was undertaken to investigate the gross response and energy utilization of broiler chicks fed on vegetable protein or conventional diets. Two hundred and fifty-two day-old Cobb-500 male broiler chicks were randomly assigned to five experimental groups and raised on a control diet (containing tallow) or diets containing fish meal (SBM50 and Can50) or diets with no animal products (SBM75; Can75) (predominantly soybean or canola meal). Birds were...
