低蛋白饲粮添加植酸酶和非淀粉多糖酶对生长猪生长性能和养分排泄量的影响
The effects of environment protecting diet on growth performance and nutrient excretion of growing pigs
摘要
Abstract
The experiment was conducted to explore the effects of phytase and Non-starch ploysaccharide enzyme (NSPase) on growth performance and nutrients excretion of growing pigs. 54 DLY pigs with initial body weight of (41.92 ±2.6) kg were randomly allocated into 3 groups of 3 replicates with 6 pigs in each replicates. Group 1 was control with diet of crude protein (CP) 17.4%. Group 2 to 3 was experiments with low protein diet (CP 14.3%). Compared to group 1, the CP and total P (TP) level reduced 3%and 0.1%level respectively in group 2. In group 3, the diets were added with NSPase on the base of group 2. The experiments lasted for 38 days. The results showed as follows: Compared with control, the average daily gain (ADG) and ratio of feed to gain (F/G) in group 2 significantly increased 7.64%and 1.94%respectively (P<0.05), and fecal nitrogen (N) excretion in group 2 to 3 significantly decreased 18.58%and 23.0%respectviely (P<0.05), fecal phosphorous (P) excretion in groups 2 to 3 decreased 40.23%, and 39.08%respectively (P<0.01). In conclusion, these results indicated that diets containing phytase with reducing 3% CP and 0.1% TP level on the base of commom CP diet can improve ADG and decrease fecal N (P<0.05) and reduce fecal P(P<0.01). But these dietary supplementation of NSPase had no influence on growth performance and fecal nutrients.关键词
