不同剂量复合中草药对江口萝卜猪生长性能、血清指标和肉品质的影响OA

The experiment aimed to investigate the effects of different doses of compound Chinese herbal medicine on the growth performance,serum indices,and meat quality of Jiangkou Luobo pigs.A total of 24 healthy weaned Jiangkou Luobo pigs with an initial body weight of(14.00±0.30)kg were randomly divided into four groups,with six replicates per group and one pig per replicate.The control group was fed a basal diet,while experimental groups Ⅰ,Ⅱ,and Ⅲ were fed the basal diet supplemented with 0.5%,1.0%,and 1.5%of the compound Chinese herbal medicine,respectively.The pre-test period was seven days,and the formal test period was 42 days.The results showed that compared with the control group,the average daily feed intake(ADFI)in experimental groups Ⅰ,Ⅱ,and Ⅲ was significantly increased(P<0.05),the feed-to-gain ratio(F/G)of experimental group Ⅲ was extremely reduced(P<0.01).The serum immunoglobulin G(IgG)content in experimental groups Ⅰ,Ⅱ,and Ⅲ was significantly increased(P<0.05),whereas the interleukin-4(IL-4)content was significantly decreased(P<0.05).The total antioxidant capacity(T-AOC)in experimental group Ⅰwas significantly decreased(P<0.05).The shear force and drip loss in experimental groups Ⅰ,Ⅱ,and Ⅲ tended to decrease,while cooking yield tended to increase,and the loin eye area was extremely increased(P<0.01).The study shows that dietary supplementation with 0.5%to 1.5%of the compound Chinese herbal medicine can enhance immune function,improve growth performance,and show a tendency to improve meat quality,and the optimal effect is achieved at a dosage of 1.5%.
