Effects of Huoxiang longhuang powder on serum biochemical,antioxidant and immune indexes in fattening cattle
The study aimed to investigate the effect of Huoxiang longhuang powder on the serum biochemical,antioxidant and immune indexes of fattening cattle.Eighty healthy,disease-free,well-conditioned Simmental crossbred cattle with an average weight of(385.0±16.3)kg and similar age were selected and randomly divided into four groups,with four replicates in each group and five cattle in each replicate.The cattle in the control group,experimental group Ⅰ,experimental group Ⅱ,and experimental group Ⅲ were fed with rations containing 0,1%,2%,and 4%Huoxiang longhuang powder,respectively.The preliminary trial lasted for 10 days,followed by a formal experimental period of 60 days.The results showed that compared to the control group,the total protein,globulin content,and alkaline phosphatase activity of fattening cattle in the experimental group Ⅱ increased by 10.87%,17.83%and 24.82%,respectively(P<0.05),and the urea nitrogen content decreased by 20.25%(P<0.05).Compared to the control group,the superoxide dismutase,catalase activities,and total antioxidant capacity in the serum of fattening cattle in the experimental group Ⅱ increased by 36.70%,28.63%and 35.28%,respectively(P<0.05).The concentrations of immunoglobulin A and immunoglobulin G of fattening cattle in the experimental group Ⅱ increased by 18.99%and 29.98%,respectively(P<0.05).The study indicates that adding 2%Huoxiang longhuang powder to the diet of fattening cattle can improve the serum biochemical indexes,promote the deposition of fat and protein,and enhance antioxidant and immunity capabilities.
