Abstract
Abstract
The impact of adding a laboratory-produced phytase to lactating buffaloes diets compared to commercial phytase (Axtra® PHY) on the nutrients digestibility, fecal excretion of calcium (Ca), phosphorus (P), magnesium (Mg) and some blood biochemical parameters, as well as milk yield composition was evaluated. Twelve lactating buffaloes were randomly divided into three groups, four animals each, using a complete random design. The entire experimental period was 105 day. The experimental groups were: G1 (control): buffaloes fed the experimental ration (ER, 60% concentrate feed mixture : 40% berseem hay) without enzyme, G2: buffaloes fed ER plus 1200 IU of the commercial enzyme and G3: buffaloes fed ER plus 1200 IU of the produced enzyme (PE). Phytase supplementation from both sources resulted in significant improvement (P
