The aim of the study was to develop an algorithm for compounding feed mixtures with inclusion probiotic strains. authors have developed basic principles underlying modeling additive formulations. However, introduction viable cells beneficial microorganisms (probiotics) into significantly increases requirements level design products. Thus, article describes designing products poultry. A technolo...

There is growing concern with regard to the continued emergence of antibiotic resistant bacteria, which pose a significant risk to both human and animal health. Antibiotics have been used as therapeutic agents in agriculture since the 1940 s and in subtherapeutic doses as food additives to improve feed conversion of livestock and domestic poultry since the 1950's. However, the use of antibiotic...

The study was conducted to evaluate the effect of artificial feed and adding organic manures to the earthen ponds on the growth and body composition of genetically improved farmed tilapia (GIFT). A total of 160 fish were stocked in each of the two ponds for 90 days. Fish in both ponds were fed with supplementary feed containing 30% crude protein at 4% body weight. Pond 1 was fertilized using co...

The use of selenium as animal feed supplement in Serbia was approved in 1989 for some categories of pigs, sheep and poultry. From 2000 selenium in animal feed became a requirement for all categories of farm animals. The aim of this study was to determine the consumption of selenium by Serbian livestock and in poultry production between 1990-1991 and 2000-2008 and to analyze the selenium content...

Recent advances in our understanding of feed efficiency in livestock have moved the focus of much of the scientific community, possessing an interest in this important aspect of animal production, to a trait known as residual feed intake (RFI). This approach to understanding feed efficiency was first proposed as having potential for use in beef cattle by Koch et al. (1963), but is now being ext...

Fermentation is a process of preserving feed ingredients, causing chemical changes in ingredients as result enzyme activity that produces CO2 and alcohol from for Livestock Development Through Feed Technology the City Tidore Islands carried out on development poultry, especially Kampong chicken. The Innovation Village program through training processing bran which waste rice milling source crud...

The current study was undertaken to estimate variance components for phytate P bioavailability (PBA) and the genetic correlations among PBA with growth and feed utilization (or intake) traits in an unselected random mating chicken population. Pedigreed data from 901 Athens-Canadian randombred chickens hatched from 26 sires, 71 dams, and 105 grandparents were used for estimation of genetic param...

Necrotic enteritis (NE) is an emerging economically significant problem of poultry caused by a bacterium Clostridium perfringens. The rising incidence of Clostridium infections and development of NE in commercial chickens has been associated with the withdrawal of antibiotics. There is an urgent need to control NE after European ban on the use of antibiotics as growth promoters in animal feed. ...

Moulds are capable of reducing the nutritional value of feedstuff as well as elaborating several mycotoxins. Mycotoxin-contaminated feed has adverse effects on animal health and productivity. Also, mycotoxins may be carried over into meat and eggs when poultry are fed with contaminated feed. In a point prevalence study feedstuff used for poultry nutrition in Argentina was analyzed for fungal fl...

The cost of feed is the most important cost in pig or poultry (meat, egg, etc.) production (#6070%); the energy component represents the greatest proportion (>80%) of that cost; while protein and minerals (phosphorus mainly) supplies in feed are much less expensive but crucial for performance of animals and levels of wastes and potential pollutions in the environment. Therefore, it is important...
