【摘要】：为探讨复方中药提取物对生长育肥猪生长性能、血液理化指标及肉质的影响,试验选择仔猪72头,分为空白对照组、抗生素组和中药提取物组3组。试验期分为前期(32 d)、中期(75 d)和后期(108 d)3个阶段。结果表明:复方中药提取物在各阶段及全程均提高了育肥猪的平均日增重,降低了发病率,而抗生素只有在前期效果较明显;复方中药提取物组总蛋白(TP)在试验前期显著高于对照组(P0.05),复方中药提取物组白蛋白(Al B)在各阶段均显著高于对照组(P0.05),而抗生素组只有前期显著高于对照组(P0.05);复方中药提取物组尿素氮(BUN)在前期与中期均显著低于对照组(P0.05)。复方中药提取物对p H24h、肉色的a*和b*、大理石纹、失水率和肌肉嫩度均有显著改善效果。
[Abstract]:In order to study the effects of compound Chinese medicine extract on growth performance, blood physical and chemical index and meat quality of growing and fattening pigs, 72 piglets were selected and divided into three groups: blank control group, antibiotic group and Chinese medicine extract group. The experiment period was divided into three stages: early stage (32 d), middle stage (75 d) and late stage (108 d). The results showed that the average daily gain of fattening pigs was increased and the incidence rate was decreased by compound Chinese medicine extract in all stages and in the whole process, but the effect of antibiotics was obvious only in the early stage. The total protein (TP) in the compound Chinese medicine extract group was significantly higher than that in the control group (P0.05), while the albumin (Al B) in the compound Chinese medicine extract group was significantly higher than that in the control group (P0.05). The antibiotic group was significantly higher than the control group only in the early stage (P0.05). The (BUN) of urea nitrogen in the extract group was significantly lower than that in the control group (P 0.05). The compound extract of traditional Chinese medicine can significantly improve pH 24 h, meat color A * and B +, marbling, water loss rate and muscle tenderness.
