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.
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...

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...

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...

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...

Ensuring high levels of hatchability resulting in viable, strong chicks is crucial for efficient broiler production systems. Several factors influence this, including health, nutrient availability and utilization in the parent stock. The transfer of maternal immunoglobulins (Ig) to the embryonic chick is important if the hatchling is to be suitably robust to survive the first days of life, before its acquired immune system is mature enough to protect it. A well developed innate...

After 50 years of routine usage, in-feed antibiotic growth promoters (AGPs) have been banned from animal feeds within the EU since the end of 2005. During this period of routine use management systems for pigs and poultry have changed dramatically and there was considerable concern that the in-feed ban would result in poorer performance and increased health problems. Consequently over the past several years much research effort has been devoted to investigating alternative feed additives...
