Abstract

This experiment was conducted to investigate the effects of bamboo vinegar powder on growth performance, blood physiological and biochemical indexes, and serum antioxidant and immune indexes of weaned Hu sheep. Ten healthy weaned Hu sheep with similar body weight at the age of 2 months were selected and randomly divided into 2 groups with 5 sheep per group, and they were fed a basal diet (control group) and the basal diet+5% bamboo vinegar powder (experimental group), respectively. The pre-feeding period lasted for 7 days, and the formal experiment period lasted for 21 days. The results showed that the differences of final weight and average daily weight gain of weaned Hu sheep in the experimental group were not significant compared with the control group (P>0.05). The blood white blood cell count of weaned Hu sheep in the experimental group was extremely significantly higher than that in the control group (P<0.01), and the red blood cell count, hemoglobin concentration and mean corpuscular hemoglobin of weaned Hu sheep in the experimental group were significantly higher than those in the control group (P<0.05); the activity of amylase in blood was significantly lower than that in the control group (P<0.05), the activities of aspartic acid transferase and alanine aminotransferase and the content of urea nitrogen were lower than those in the control group, and the contents of triglyceride and creatinine were higher than those in the control group, but the differences were not significant (P>0.05); moreover, the interleukin-2 content in serum was significantly higher than that in the control group (P<0.05), and the interferon-γ content tended to be higher than the control group (P=0.053). Above all, adding 5% bamboo vinegar powder in the weaned Hu sheep diet has no significant effect on the growth performance, but can extremely significantly or significantly increase the blood white blood cell count, red blood cell count, hemoglobin concentration and mean corpuscular hemoglobin, significantly reduce the blood amylase activity, and significantly or tend to increase the serum interleukin-2 and interferon-γ contents. This shows that 5% bamboo vinegar powder can improve the disease resistance and immunity of weaned Hu sheep in the whole.
