中草药添加剂对生长肥育猪血液生理生化指标的影响

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

选用 2 0kg左右的“杜长大”三元杂交猪 12 0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 2 0～ 30kg和 30～ 70kg阶段 ,血清TP含量分别增加了 13 74 % (P <0 0 5 )和 11 13% (P <0 0 5 ) ;GLO含量分别提高了 35 79% (P <0 0 5 )和 19 88% (P <0 0 5 ) ;CHO含量分别提高了19 6 4 % (P <0 0 5 )和 12 39% (P <0 0 5 ) ;TG3 含量分别提高了 2 2 35 % (P <0 0 5 )和 2 1 4 3% (P <0 0 5 ) ;在 70～ 110kg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 0 5 ) .在 2 0～ 30kg ,30～ 70kg和 70～ 110kg阶段 ,GPT活性分别提高了 10 75 % (P <0 0 5 ) ,13 39% (P <0 0 5 )和12 2 6 % (P <0 0 5 ) ;GOT活性分别提高了 10 88% (P <0 0 5 ) ,14 16 % (P <0 0 5 )和 11 13% (P <0 0 5 ) ;ALP活性分别提高了 33 5 0 % (P <0 0 5 ) ,12 14 % (P <0 0 5 ) 12 2 1% (P <0 0 5 ) .LDL ,VLDL的含量仅在 70～ 110kg阶段 ,分别比对照组高了 18 5 1% (P <0 0 5 ) 。

The trial was conducted to investigate the effect of Chinese herb feed additives on the content of TP,ALB, GLO, CHO, TG 3,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 TG 3 during the growing period of 30～70?kg. No significant difference was found in each group of the content of serum TP,GLO,CHO,TG 3 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,T 3,T 4,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.
