1. IntroductionThe poultry diet is balanced for metabolizable energy and protein through the incorpo ration of several ingredients and additives. The cost of many cereal grains and legumes used in making poultry feed is increasing due to the growing markets utilizing them as food and fuel [1]. To counter this, alternative feedstuffs such as agricultural co-products, including wheat middlings, soy ...

IntroductionFeed ingredients and manufacturing are expensive components of integrated poultry production, sometimes reaching 70% of total operational costs. Fortunately, the added costs of manufacturing poultry feed improve feed efficiency and poultry performance. The performance benefits from feeding pelleted diets results in a positive return on investment, making it a common practice in broiler ...

I. INTRODUCTIONGlobally, maize and wheat are the major cereal grains used in broiler feed. Maize is predominant in Asia and the Americas, whereas wheat is in Australia, New Zealand and Europe. Extensive research has been undertaken in refining dietary strategies to optimise broiler performance when offered reduced crude protein (CP) diets. In feed, these grains have been optimized by the inclusion ...

1. IntroductionAvian Reovirus (ARV) poses a significant threat to the poultry industry, infecting both domestic and wild avian species. ARV infections manifest in a diverse range of clinical signs, encompassing tenosynovitis/arthritis, immunosuppression, enteric disease, hepatitis, myocarditis, malabsorption, and runting–stunting syndrome [1,2]. While domestic avian species are generally sus ...

DESCRIPTION OF PROBLEMThere are growing concerns that the continual feeding of inorganic P is leading to the development of eutrophication of surface waters. Excessive P runoff from soil causes an accumulation of P in water sources, and this can result in toxic algal blooms and fish kills [1]. The availability of P from feedstuffs of plant origin is low for poultry because a greater proportio ...

I. INTRODUCTIONWith the current genetic focus being on longer laying cycles, there is a need to look for new ways of improving calcium metabolism in laying birds which are prone to osteoporosis in the latter stages of lay (Bain et al, 2016). Calcium pidolate (a highly soluble, absorbable salt with excellent gastrointestinal tolerance) has been around for 10-15 years in the commercial sector of the ...

1. IntroductionOver the years, broiler chickens have been selected for rapid growth, which makes them very efficient at depositing body protein in a short period of time. This is important since the broiler sector is expected to contribute to the growing global demand for poultry meat. In light of this, the quality of proteins fed to poultry is becoming more important. Animal and plant ingred ...

1. IntroductionAflatoxin B1 (AFB1), a toxic metabolite produced by Aspergillus flavus and Aspergillus parasiticus, is one of the most potent naturally occurring carcinogens [1]. It poses significant risks to animal health and productivity, particularly in poultry, where the contamination of feed is a prevalent issue [2]. Broiler chickens are highly susceptible to the adverse effects of AFB1 due to ...

IntroductionCurrent poultry production targets at reducing productions costs and nitrogen excretion into the environment while maintaining an effective animal performance. The key to limit nitrogen excretion is a reduction of the protein content of the diet with concurrent supplementation of deficient and (performance-)limiting amino acids (AA). The aim is to provide balanced quantities of individ ...
