中草药添加剂对生长肥育猪血液生理生化指标的影响

 选用20 kg左右的“杜长大”三元杂交猪120头,分成对照组、中药组、中药+西药组,每组4个重复。测定添加中草药添加剂,对生长育肥猪血清中TP,ALB,GLO,CHO,TG₃,HDL,LDL和VLDL的含量以及GPT,GOT和ALP活性的影响。结果表明:中药组与对照组相比,在20～30 kg和30～70 kg阶段,血清TP含量分别增加了13.74%（P<0.05）和11.13%(P<0.05);GLO含量分别提高了35.79%（P<0.05）和19.88%（P<0.05）;CHO 含量分别提高了19.64%（P<0.05）和12.39%（P<0.05）;TG₃含量分别提高了22.35%（P<0.05）和21.43%（P<0.05）;在70～110 kg阶段,血清TP,GLO,CHO和TG₃含量各组之间差异不显著;ALB含量在不同生长阶段,各组之间差异都不显著（P>0.05）.在20～30 kg,30～70 kg和70～110 kg阶段,GPT活性分别提高了10.75%（P<0.05）,13.39%（P<0.05）和12.26%（P<0.05）;GOT活性分别提高了10.88%（P<0.05）,14.16%（P<0.05）和11.13%（P<0.05）;ALP活性分别提高了33.50%（P<0.05）,12.14%（P<0.05）12.21%（P<0.05）. LDL,VLDL的含量仅在70～110 kg阶段,分别比对照组高了18.51%（P<0.05）,14.85%（P<0.05）,在猪其它不同的生长时期,血清HDL,LDL和VLDL的含量,各组之间都无显著差异（P>0.05）。研究结果提示,中草药添加剂对生长育肥猪的促生长、改善胴体品质和肉品质的作用,可能是通过神经-内分泌系统来实现的,通过GH,IGF-I,T₃,T₄,cAMP等内分泌激素以及GPT,GOT及ALP等酶的协同作用,改善体内生理生化过程,使体内蛋白质代谢加强,氨基酸利用率提高;肝脏脂肪代谢加强,体脂肪沉积减少,肌间脂肪沉积增加。

Effect of Chinese Herb Feed Additives on the Biological and Biochemical Index of Blood in Growing and Finishing Pigs

The trial was conducted to investigate the effect of Chinese herb feed additives on the content of TP,ALB, GLO, CHO, TG₃,HDL,VHDL and the activity of GPT,GOT and ALP in the serum of growing and finishing pigs. 120 growing and finishing pigs (Duroc×Landrace×Yorkshire,20 kg initially) were assigned into control and three treat group set with four replicate pens per treatment by weight and sex. treatment group 1,treatment group 2 and treatment group 3 fed basic diet supplemented with Chinese herb feed additives, Chinese herb feed additives + antibiotic/chemical compound drug and antibiotic respectively. Comparing with control group, Chinese herb feed additives was increased 13.74% (P＜0.05) and 11.13% (P＜0.05) of the content of TP,35.79% (P＜0.05) and 9.88% (P＜0.05) of the content of GLO, 19.64% (P＜0.05) and 12.39% (P＜0.05)of the content of CHO, 22.35% (P＜0.05) and 21.43% (P＜0.05)of the content of TG₃ during the growing period of 30～70 kg. No significant difference was found in each group of the content of serum TP,GLO,CHO,TG₃ during the growing period of 70～110 kg and the content of ALB during each growing period. It was increased 10.75% (P＜0.05), 13.39% (P＜0.05) and12.26% (P＜0.05) of the activity of GPT, 10.88% (P＜0.05),14.16% (P＜0.05) and 11.13% (P＜0.05) of the activity of GOT, 33.50%(P＜0.05) ,12.14%(P＜0.05) and 12.21%(P＜0.05) of the activity of ALP in the growing period of 20～30,30～70,70～110kg respectively. The content of LDL,VLDL were increased 18.51%(P＜0.05), 14.85% (P＜0.05) only during the growing period of 70～110 kg.The content of HDL, LDL, VLDL had no significant difference during its different growing period in each group.The results indicated that the effect of Chinese herb feed additives on improving growing performance, carcass characteristics and meat features perhaps though the system of nerve-internal secretion and the effect of hormone of GH,IGF-1,T₃,T₄,cAMP and the enzyme of GPT,GOT and ALP, improving the course of the biological and biochemical of the body to enhance the metabolism of protein, to enhance the digestibility of AA and the metabolism of fat in liver was enhanced ,the deposition of carcass fat decreased and the intramusclar fat increased.
