Poultry diets are formulated primarily using cereals and protein meals (corn, wheat and soybean meal) as the main ingredients. There is noted shift in using coproducts from cereals and oilseeds in poultry diets due to availability and relatively lower cost. However, there is wide variation in the nutritional values of both conventional feedstuffs and coproducts, which creates a necessity of dev...

The objectives of this review are to provide 1) information on the FDA Feed Contaminants Program, 2) the legal history of aflatoxins and their current action levels, 3) a report on the levels of aflatoxins, fumonisins, vomitoxin, ochratoxin A, and zearalenone in domestic and import surveillance samples of feed during fiscal years 1989 through 1992, and 4) information on naturally occurring toxi...

Measurements were made on protein sup,plcments in.a basal diet, of dry matter, nitrogen and amino acid digestibilities using mature and' adult cockerels. Birds were killed 5h after receiving their diet in a single feed. Analyses were made on digesta from (i) the ileum, (ii) the terminal ileum, (iii) post caeca, and on excreta. In a second exDeriment -adult cockerels were fitted with a sitiple c...

Recent studies pointed out that live insects and their products (meals oils) are suitable protein fat sources can be used in the nutrition of farmed monogastric animals. This is as an alternative to traditional plant-derived animal-derived feedstuffs. To date very little information available concerning effects dietary inclusion on feed digestibility performance ruminant The aim this editorial ...

High corn and soybean meal prices, and in some cases, reduced availability, are causing nutritionists to use more by-products and co-products than ever before in order to minimize diet costs. The three most common by-products being used in swine diets are DDGS, wheat midds, and bakery by-product. Managing nutrient variability among by-product sources is the primary challenge to obtaining accura...

Assessing amino acid (AA) availability in dietary ingredients is integral to the optimal formulation of diets both in terms of maximising nutrient utilization and profitability. Although the concept that nutrients in feedstuffs are not fully absorbed and metabolized by the animal is now widely accepted, a distinction needs to be made between the concepts of digestibility and availability. Diges...
