Feedstuffs of plant origin do not contain enough digestible phosphorus to meet the requirements for animal production. For this reason additional inorganic P is added to animal diets. Feedstuffs of plant and animal origin as well as inorganic phosphate sources contain various amounts of phosphate that is available for biochemical functions. Therefore most Nutritionists include a safety factor t...

A case is made for the application of true ileal amino acid digestibility and true ileal reactive lysine digestibility (lysine availability) in poultry nutrition. Technical aspects of the true ileal digestibility assays are reviewed, as are factors influencing amino acid digestibility in the broiler. There is considerable variation in amino acid digestibility and lysine availability both within...

The effects of physical processing of forage diets on their value as feedstuffs for ruminants has been reviewed by Minson (1963)~ Beardsley (1964), Moore (1964), Campling & Milne (1972), Greenhalgh & Wainman (1972), Jarrige, Demarquilly, Journet & Beranger (1973) and Wilkins (1973). In this review we have therefore attempted to concentrate attention upon the chemical and physical changes produc...

AIM The aim was to determine the chemical composition and metabolisable energy (ME) content of feedstuffs used in ruminant animals using in vitro method. MATERIALS AND METHODS A total of 18 feedstuffs used for ruminant feeding including cultivated non-leguminous fodders like maize, sorghum, pearl millet, and oat; leguminous fodders like cowpea and berseem; agro-industrial by-products such as ...

Both plant and animal ingredients are used commonly to formulate balanced diets for poultry. Although many changes have been occurred in the genetics, nutrition and feeding of modern meat chickens, free selection and indiscriminate uses of feedstuffs for the non-ruminant animal diets can be hazardous due to the emerging threat of diseases outbreak via animal by-products. Besides this, many othe...

Market availability and price of conventional feedstuffs are variable, making imperative to explore alternative feedstuffs. Cassava (Manihot esculenta) is a starchy tuber that can be a potential feedstuff for swine. Three sample type (combinations of cassava parts): 100% tubers (T100), 50% tubers and 50% leaves (T50), and 25% tubers and 75% leaves (T25) were ensiled over three periods [fresh (M...

The disappearance of dry matter (DM), crude protein (CP), and amino acids (AA) in steers after rumen incubation and intestinal passage of alfalfa hay, barley hay, corn silage, barley grain, corn grain, wheat bran, meat meal, fish meal, cottonseed meal, and soybean meal were measured in 3 steers using a mobile nylon bag technique. Ruminal degradation of individual AA differed between feedstuffs....

In this study, a desorption electrospray ionization-high resolution mass spectrometry (DESI-HRMS) screening method was developed for fast identification of veterinary drugs in cross-contaminated feedstuffs. The reliable detection was performed working at high resolution (70,000 full width half maximum, FWHM) using an orbitrap mass analyzer. Among the optimized DESI parameters, the solvent (acet...

Thirty-two Alpine doelings (15 wk of age, 12 ± 2.05 kg) were randomly allocated to four treatments to evaluate the use of deep-stacked broiler litter (BL) and urea-treated wheat straw (UWS) as feedstuffs. In all treatments, UWS or untreated wheat straw (WS) was fed for ad libitum consumption along with a concentrate supplement fed at a prescribed percentage of BW. Treatments were: U B a corn-ba...
