【摘要】：本试验旨在研究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。选取日龄和体重相近[(83.18±1.62)kg]、生长状况良好的"长×白×杜"三元杂交育肥猪18头,随机分成2组,每组9个重复。对照组饲喂基础饲粮,试验组在基础饲粮中添加40 mg/kg的二丁酰环磷腺苷钙。试验期30 d。结果显示,与对照组相比:1)饲粮中添加二丁酰环磷腺苷钙使肥育猪日增重提高了30.12 g(P0.05);2)饲粮中添加二丁酰环磷腺苷钙显著降低了肥育猪血清乳酸脱氢酶活性(P0.05),同时显著提高了血清中尿素的含量(P0.05);3)饲粮中添加二丁酰环磷腺苷钙显著降低了肥育猪血清非必需氨基酸中的丝氨酸、甘氨酸和天冬氨酸的含量(P0.05),同时显著提高了必需氨基酸中的苏氨酸、色氨酸、缬氨酸、苯丙氨酸和异亮氨酸的含量(P0.05)。以上结果表明,二丁酰环磷腺苷钙在一定程度上能改善肥育猪的生长性能,这可能与其促进氨基酸的代谢相关。
[Abstract]:The aim of this study was to study the effects of calcium dibutyrylcyclophosphate on growth performance and serum biochemical indexes of finishing pigs. Eighteen crossbred fattening pigs with similar body weight and age [(83.18 卤1.62) kg] and good growth condition were randomly divided into 2 groups with 9 replicates in each group. The control group was fed with basic diet, and the experimental group was fed with 40 mg/kg dibutyrylcyclophosphate adenosine calcium. The trial period was 30 days. The results show that Compared with the control group: 1) the daily gain of fattening pigs was increased by 30.12 g (P0.05), and the activity of lactate dehydrogenase (LDH) in serum was significantly decreased (P0.05). The content of urea in serum (P0.05); (3) addition of dibutyryl cyclic adenosine in diet significantly decreased serine in serum non-essential amino acids of fattening pigs. The contents of glycine and aspartic acid (P0.05) and the contents of threonine, tryptophan, valine, phenylalanine and isoleucine in essential amino acids were significantly increased (P0.05). The results indicated that calcium dibutyrylcyclophosphate can improve the growth performance of fattening pigs to some extent, which may be related to the promotion of amino acid metabolism.
