二丁酰环磷腺苷钙对肥育猪生长性能和血清生化指标的影响
Effects of Dibutyryl Cyclic Adenosine Monophosphate-Calcium on Growth Performance and Serum Biochemical Indices of Finishing pigs
摘要
Abstract
This study was conducted to investigate the effects of dibutyryl cyclic adenosine monophosphate⁃cal⁃cium ( dbcAMP⁃Ca) on growth performance and serum biochemical indices of finishing pigs. Eighteen healthy crossbred (Landrace×Large White×Duroc) barrows with the body weight of (83.18±1.62) kg and similar age were randomly allotted to two groups with nine replicates each. The pigs were fed with the basal diet ( con⁃trol) , or the basal diet supplemented with 40 mg/kg dbcAMP⁃Ca. The trial lasted for 30 days. The results showed that, compared with control group: 1 ) dietary dbcAMP⁃Ca tended to improve daily gain of finishing pigs by 30.12 g ( P>0.05);2) dietary dbcAMP⁃Ca significantly decreased serum lactic dehydrogenase activity and increased serum urea content ( P<0.05); 3) dietary dbcAMP⁃Ca significantly reduced serum contents of non⁃essential amino acids, such as Ser, Gly and Asp ( P<0.05) , and increased serum contents of essential a⁃mino acids, including Thr, Val, Ile, Phe and Trp (P<0.05). The results indicate that the dbcAMP⁃Ca can improve the growth performance by affecting the amino acid metabolism of finishing pigs.关键词
