摘要: An experiment was conducted to assess the effects of a novel thermostable phytase in male broiler chicks (Ross 308) fed available P (AP)-deficient diets on growth performance and bone mineralization. The treatments consisted of 8 experimental diets: 1 positive control diet containing an adequate level of AP, 1 negative control diet deficient in AP, and 6 diets with the same level of AP as in the negative control but supplemented with different levels of phytase (250, 500, 750, 1,000, 1,250, and 1,500 phytase units/kg of diet). The addition of phytase significantly improved (P < 0.05) BW gain, feed intake, FCR, toe ash, tibia ash, and tibia P of broilers compared with those fed the negative control diet. No significant differences (P > 0.05) were found in FCR and bone mineralization among the broilers fed different levels of phytase and those fed the positive control diet. In conclusion, normal growth performance and bone mineralization were maintained in broilers fed AP-deficient diets supplemented with thermostable phytase.
