this study was conducted to investigate the effect of replacing barley with different levels of ground date seeds (gds) in the diet (0, 15, 3o and 45%) on performance of local growing male goats. sixteen local male kids (average live weight 16.1±1.41 kg) were allocated randomly to four treatments (4 animal/treatment). the trial consisted of a 14 day acclimatization period followed by a 60-day m...

Supplementation of cows grazing rangelands is often beneficial to overcome nutrient deficiencies or imbalances. However, supplemental feeds and their delivery to the cow herd are expenses and thus supplementation decisions should be carefully made to ensure that costs are minimized and benefits in terms of cow performance exceed supplementation costs.

Bacillus amyloliquefaciens DS11 phytase (DS11 phytase) and Aspergillus ficuum phytase (AF phytase) activities were investigated by measuring the release of phosphate from phytate in animal feedstuff such as wheat bran, corn meal, soybean meal and rice flour at pH 5 and 7. In all the tested feedstuff, the enzymatic activity of DS11 phytase was more active at pH 7, but that of AF phytase was more...
