摘要
分别在种雉、育成雉基础日粮中添加不同配比的酶制剂 ,研究酶制剂对环颈雉 (种雉、育成雉 )日粮能量及营养物质表观代谢率的影响。结果表明 :各试验组环颈雉日粮能量、无氮浸出物、蛋白质表观代谢率均高于对照组 ;各试验组环颈雉日粮粗纤维表观代谢率均明显高于对照组 ;各试验组育成雉日粮总磷、钙表观代谢率均不同程度高于对照组。种雉的酶制剂推荐添加方案为 0 5 %纤维素酶 +0 5 %中性蛋白酶 ;育成雉的酶制剂推荐添加方案为 1 2 %ZY
The effects of enzyme preparations on apparent metabolic rates of energe and nutrient components in diets of pheasants were primarily studied The basal diets of breeding and growing pheasants were supplemented with relevant enzyme preparations, respectively By metabolism experiments, the results showed that the apparent metabolic rates of energe, nitrogen free extraction and protein for each experimental group of pheasants were higher than those of control; the apparent metabolic rates of crude fibre for each experimental group of pheasants was significantly higher than that for control; the apparent metabolic rates of total phosphorus and calcium for each experimental groups of pheasants were higher than those for control in some degree To sum up, the recommended adding scheme of breeding pheasant was 0 5% cellulose enzyme+0 5% neutral protein enzyme; the recommended adding scheme of growing pheasant was 1 2% compound enzyme (Type: ZY-Ⅱ)
