摘要: 利用植酸酶可以水解植物性饲料中植酸的原理,探讨在产蛋鸡饲料中添加商品植酸酶替代不同水平磷酸氢钙的效果。选用50~54周海兰褐产蛋鸡为试验对象,在每千克饲料中添加400FYT植酸酶分别替代8g、16g的磷酸氯钙,观测植酸酶对产蛋鸡生产性能的影响。结果显示,用400FYT植酸酶替代16g磷酸氢钙可以保持产蛋鸡生产性能不变,而替代8g磷酸氢钙可以提高产蛋鸡的生产性能。只日产量、产蛋率、料蛋比分别提高3.4%、3.6%、3.7%。因此,在产蛋鸡饲料中用400FYT植酸酶替代8g磷酸氢钙可以提高产蛋鸡生产性能,同时也可以降低饲料配方中的总磷。

Abstract: The effect of adding commodity phytase into the laying hens' feed to substitute dicalcium phosphate (DCP) with different level was explored and discussed by using the principle of phytase being able to hydrolyze phytic acid in plant feedstuffs. 50 to 54-week-old Hy-line brown laying hens were selected as experiment objects, 400 FYT phytase were added in every 1 000 kg feedstuff to replace 8 g and 16 g of DCP resp. to observe the influence of phytase on the performance of laying hens. The results showed that the performance of laying hens could keep steady by replacing 16 g DCP with 400 FYT phytase, while the performance of laying hens could be enhanced with substitution of 8 g DCP. The daily egg output, laying rate and feed-egg ratio raised 3.4 %, 3.6 % and 3.7 % resp., therefore, the performance of laying hens could be enhanced by replacing 8 g DCP with 400 FYT phytase in the laying hens' feed and total phosphorus in feed formula could be reduced as well.
