降低日粮氮磷水平对仔猪血液指标、碱性磷酸酶活性及骨骼钙磷含量的影响
Effect of reduced nitrogen and phosphorus level in diet on serum biochemical parameters, alkaline phosphatase activities, calcium and phosphorus contents in bones of piglets
摘要
Abstract
To investigate the effect of reduced nitrogen and phosphorus level in diet on serum biochemical parameters,alkaline phosphatase activities,calcium and phosphorus contents in bones of 60 piglets were selected and randomly divided into control group,low-phosphorus group (LP),low nitrogen and low phosphate group (LNP),and were fed with corn-soybean meal diets containing 17.5％ CP +0.60％ P,17.5％ CP + 0.42％ P + 0.1％ phytase,15.10％ CP + 0.42％ P + 0.1％ phytase + AA respectively.The trial lasted 47d.The results showed that 1) compared with control group,the serum glucose content of LP and LNP group was significantly decreased (P ＜ 0.05).For the LNP group,the serum phosphate,total protein,and globulin concentrates were significantly lower than that of the control group (P ＜ 0.05),but had no significant difference from that of the LP group (P ＞ 0.05).2) The AKP activities in serum and in rib of LP and LNP group were significantly increased compared with those fo the control group (P ＜ 0.05).The Duodenal KAP of LP and LNP group was also increased compared with the control group,but there were not significant difference among the groups (P ＞ 0.05).3) The calcium and phosphorus contents in bone does not have any significant difference among the groups (P ＞ 0.05).This suggests that reducing levels of nitrogen and phosphorus in the diet does not affect the content of calcium and phosphorus in bone,and does not have any significant effect on bone strength.关键词
