15 صفحه اولBiotechnological Advances for Animal Nutrition and Feed Improvement
Shortage of animal feed in most developing countries and the increasing cost of feed ingredients mean that there is a need to improve feed utilization. Although developing countries accommodate a majority of the world’s people, there is a risk that biotechnology research and development may by-pass their requirements. However, there are beginnings of using biotechnology in animal production par...
متن کاملThermostable Alkaline Phytase from Alcaligenes sp. in Improving Bioavailability of Phosphorus in Animal Feed: In Vitro Analysis
A bacterial isolate, Alcaligenes sp. secreting phytase (EC 3.1.3.8), was isolated and characterized. The optimum conditions for the production of phytase included a fermentation period of 96 h, pH 8.0, and the addition of 1% (w/v) maltose and 1% (w/v) beef extract to the culture medium. This enzyme was purified to homogeneity and had an apparent molecular mass of 41 kDa. The optimum pH range an...
متن کاملBioavailability of Phosphorus in Two Cultivars of Pea for Broiler Chicks.
The aim was to determine the relative bioavailability of phosphorus (P) in peas for 21-day old broiler chickens using slope-ratio assay. One hundred and sixty eight male Ross 308 broiler chicks were divided into 42 groups 4 balanced for body weight and fed 7 diets in a completely randomized design (6 groups/diet) from day 1 to 21 of age. The diets were a corn-soybean meal basal diet, and the co...
متن کاملPreference of Broiler Chickens for Feed Color
Studying broiler preference to feed color is important for improving comfort and welfare of broilers and it may be beneficial for improving performance.
