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.
The unprecedented increase in feed prices during the past year are by now an unfortunate matter of record. The cost of virtually all feed ingredients, especially corn, soybean meal, phosphate, fat and even vitamins has gone far beyond any reasonable expectation. A number of causes for the current crisis have been cited, and their respective magnitudes debated, but it is certain that the massive diversion of feed ingredients to biofuels, reduced crop yields, and an increased demand for animal...

For many decades, Georgia has been one of the leading poultry states in the nation. Unfortunately, the need for feed components such as corn and soybean meal far exceeds the state’s ability to produce these ingredients. Thus, enormous quantities of grain and high protein oilseed meals are routinely imported from the mid-west. An ongoing project of the Poultry Science Department at the University of Georgia has been to investigate means of increasing the use of Georgia agricultural...

Genetic progress and nutritional consequences Just as for the other species, genetic progress has a considerable influence on dietary amino acid concentrations. Over the last 30 years, production to a constant age has increased by more than 40 %, while feed consumption has been reduced by...

The rapid emergence of ethanol plants in Indiana will result in a large quantity of corn co-products that could be used to feed poultry. The primary co-product available is fed as dried distillers’ grains with solubles (DDGS); however, the quantity that may be fed may be limited because there are numerous issues affecting use of DDGS in poultry rations. Issues to Be Addressed Whether large amounts of DDGS can be fed on poultry farms...

Lucta S.A. reports that Luctarom® Convert increases fat digestibility in poultry diets. This effect is explained by previous results showing increased activity of digestive enzymes in broilers fed this phytogenic product. In digestibility trials conducted at IRTA (Spain), the feeding of Luctarom® Convert at 500 ppm improved soya bean oil digestibility by 3% and lard digestibility by 7% in 21-day old broilers. Remarkably, Luctarom® Convert made lard as digestible as soya bean oil in...

Pea production on the Prairies has increased dramatically in recent years but the use of peas in poultry diets has been limited. One of the problems faced by producers and feed mills is the variability in the feeding value of this crop for poultry. Because of this variation, people are unsure of how birds will perform on pea-based rations and reluctant to include high levels of peas in poultry feed. With the support of funding from Manitoba Egg Producers, Dr. Bill Guenter and Dr....

An innovative study at AFBI and Queen’s University (QUB) has potentially discovered an exciting new technique for defining the nutritive value of wheat for broiler chickens. The project was sponsored by the Department of Agriculture and Rural Development and the Home Grown Cereals Authority. For many years, the specific weight of wheat has been used as the internationally accepted measure of wheat quality, with an agreed arbitrary minimum value of 72 kg per hectolitre (hl) for...

An advanced microbiological technique that provides a “snapshot” of the bacterial population in the chicken’s gut is being used to determine the right balance of bacterial species for the bird's gut health. The research behind the development is part of a Poultry CRC strategy to enable the fine tuning of diets through a better understanding of the bacterial population in the chicken's gut. According to the Poultry...

There are 4 main components that go together to make up a poultry diet. While protein, vitamins and minerals are referred to as nutrients, energy the 4th and most costly part of the diet is not a nutrient but the property of energy yielding nutrients. Dietary nutrients that yield energy are protein, fat and carbohydrates. Protein is not commonly thought of as a source of dietary energy but it does result in a significant contribution to the energy requirement of the bird, and can, if...

The use of probiotics is an alternative to antibiotics as growth promoting and therapeutic in poultry production. Bacillus probiotics are growing in broiler production to replace antibiotic growth promoters and to reduce the inclusion of coccidiostat. The efficiency in pelleted broiler feeds and its compatibility with most of coccidiostat substances make it available to be included in grower feeds. This report summarizes the information about the efficiency against pathogenic bacteria...

Poultry is big business in South Carolina and Clemson University scientists are using nanotechnology to keep the birds and consumers healthy. The researchers are developing drug-free ways to keep chickens and humans from contracting illnesses. More than 200 million broilers and layers are raised in the Palmetto State. The industry has moved toward bigger broiler farms with flocks of between 150,000 and 300,000 birds becoming common. Chickens are susceptible to disease. An...

The results of 15 experiments realized from 1990 have been used to define more precisely the requirement in Methionine and Sulfur Amino Acids. Results show that the daily requirement for Methionine is related to the bird productivity. If the requirement is expressed in mg per gram of egg mass produced, the requirement appeared independent of the daily egg mass produced. From this analysis, we conclude that the Methionine requirement is not related to the Cystine...

High quality fishmeal is recognized by animal nutritionists as an excellent source of protein, energy, minerals and vitamins. Worldwide, millions of tons of fishmeal are produced annually. The majority of the fishmeal produced is included in commercial diets for poultry, swine, dairy cattle, mink and fish. Good quality fishmeal demands a higher price than other high protein feedstuffs. Its proper use, however, requires a knowledge of not only its nutrient profile but of how it was...

The increased use of corn for ethanol production has contributed to a sharp increase in corn prices, translating into higher feed costs for livestock and poultry producers. Yet one way producers can benefit from the ethanol industry is to incorporate ethanol by-products into feed rations. Several researchers at Iowa State are studying the use of dried distillers grains with solubles (DDGS) as a feed ingredient. A recent project showed laying hen diets can be formulated with high amounts...

At the last EU Standing Committee meeting of 22nd October 2007, the European Commission has granted DSM Nutritional Products an extension to the approval given to its phytase feed enzyme, RONOZYME® P, for ducks. RONOZYME® P (Granulate and liquid) is now approved for salmonids, broiler, layer, turkey, duck, sow, piglet and fattening pigs. The large spectrum of EU authorizations is of major added-value for multi-species feed factories. The European Food Safety Authority (EFSA), in charge of...

THE WATER QUALITY IMPROVEMENT ACT OF 1998 IN MARYLAND During the summer of 1997 the state of Maryland experienced outbreaks of Pfiesteria in several of its rivers and tributaries. These dinoflagellate microorganisms were implicated in several fish kills that closed affected rivers to fishing and tourism. Similar outbreaks were experienced in North Carolina and other east coast areas, and although not proven there was thought to be a link between these outbreaks and nutrient...

Chr. Hansen is ready to launch probiotic feed additive that can prevent Necrotic enteritis in commercial poultry production. Necrotic enteritis (NE) is a serious condition where chickens loose the ability to digest nutrients from the feed with the risk of a painful death within only few days. The condition causes much suffering for the chicken and represents a serious loss to the producers. Recent European surveys estimate the economic impact of NE on global poultry producers to $2...
