植酸酶在猪饲料中的应用研究

Application Research of Adding Phytase in Pig Feed

植酸酶作为一种新型的酶制剂,可以作为动物饲料添加剂使用。添加到猪饲料中后,植酸酶能提高猪对植酸磷的利用率,还能降低粪便中磷的排放,减少磷污染。不仅如此,饲料中添加植酸酶,可显著提高钙、镁、锌、锰等矿物元素的生物利用率,且促进了动物矿物质营养的平衡,进而保持动物组织结构的完整性,促进了软骨和骨细胞的有序化。植酸酶还能够促使与植酸相结合的氨基酸和蛋白质释放出来,增加消化酶量和底物蛋白质浓度,从而提高蛋白质和氨基酸的利用率。植酸酶用作猪饲料添加剂能够显著提高猪的饲料利用率和采食量,从而提高日增重、提高生产性能。

Phytase is a kind of new enzyme preparation,can be used as animal feed additives.Phytase was added to pig feed.The utilization ratio of phytase phosphorus in pig can be improved,can also reduce the discharge of phosphorus in the feces,so as to reduce phosphorus pollution.Not only that,bioavailability of calcium,magnesium,zinc,manganese and other mineral elements can be significantly improved by the addition of phytase in feed,and mineral nutrition balance has been promoted,and the integrity of the organizational structure is maintained,and arranging of cartilage cells and osteocytes can be promoted.Phytase can also encourage amino acids and proteins is decomposed from phytic acid conjugates,and then.the amount of digestive enzyme and substrate protein increased.Thus the utilization of protein and amino acid was increased.Phytase used as pig feed additives can significantly improve the feed conversion rate and feed intake,thus to improve the daily gain and the production performance.
