摘要
从营养学角度出发,初步研究了添加植酸酶的饲料经不同温度(常温、6 0℃、70℃、80℃、90℃、10 0℃)处理对鲤钙磷营养物质利用率的影响。通过 10d的饲养,收集粪便分析发现:与对照组相比,添加植酸酶可以使钙的利用率提高 132 %以上,总磷利用率提高 10 5 %～12 2 %;74.86 %～ 89.0 4 %的植酸磷得以利用;蛋白质和脂肪的利用率约提高 11%和 12 %。
The carp was fed with the diets added phytase (treated at room temperature, 60 ℃,70 ℃,80 ℃,90 ℃,100 ℃) for 10 days.The results show that the utilization ratio of calcium significantly increased by more than 132.0% by adding phytase to the diets. At the same time,the utilization ratios of total phosphorus and phytase phosphorus increased by from 105% to 122% and from 74.86% to 89.04%,respectively.Also,the utilization ratios of protein and crude lipid increased by about 11% and 12%,respectively.
