| 摘 要： | 选取同日出壳的健康樱桃谷肉鸭120羽；经1周预饲后．随机分成2组．以玉米—豆粕型基础日粮进行饲喂。其中一组添加400u／kg植酸酶，以研究植酸酶对樱桃谷鸭生产性能、胫骨和血液中钙磷含量，碱性磷酸酶及饲料中钙、磷利用率和粪便中磷排泄量的影响。试验结果表明，在相对低的无机磷日粮中，添加植酸酶可使鸭生长性能改善，提高胫骨中灰份、钙磷的沉积，提高钙、总磷和植酸磷的利用率，并减少粪磷的排出，同时使血钙、血磷浓度和碱性磷酸酶的活性维持在正常水平。

| Abstract: | 120 healthy Cherry Valley ducklings were selected and divided into two groups randomly. All ducklings were fed with the basic diet consisting mainly of corn-soybean meal,but for the experiment group 400 u/kg phytase was added to the diet in order to study its effect on the production performance, the content of calcium and phosphorus in tissues of tibia and serum, the activity of alkaline phosphatase (ALP)in serum and the utilization ratio of Ca, P, and the excretion of phosphorus in feces. The experiment results showed that: phytase added to lower inorganic phosphorus diet improved the production performance of ducks. And the utilization of Ca, P, increased the retain of Ca, P in tibia ash, and decreased the excretion of phosphorus in feces.Meanwhile, the activity of ALP and concentration of Ca, P reminded normal levels in serum. |
