Effects of Coated Betaine on Growth Performance and Serum Indexes of Pingliang Red Bull in Late Fattening Period
The purpose of this experiment was to explore the effects of coated betaine(CBet)on growth per-formance and serum indexes of Pingliang red bull in the late fattening period.A total of 18 healthy red bulls with similar weight(470.78±16.10)kg were randomly divided into 3 groups(control group,test group Ⅰand test group Ⅱ),6 bulls in each group.Among them,the control group was fed a basic diet,the test groupⅠ was fed the basic diet+3.5 g/d CBet,and the test group Ⅱ was fed the basic diet+7.0 g/d CBet.The pre-test period was 7 d and the formal period was 54 d.After the test,the growth performance,serum biochemical indexes and antioxidant function of each group were determined.The results showed as follows:1)the average daily gain(ADG)of Pingliang red bull in test group Ⅰ was significantly higher than that in the control group and test group Ⅱ(P＜0.05),while the feed/gain(F/G)was significantly lower than that in the other two groups(P＜0.05).2)The albumin(ALB),urea nitrogen(UN)contents and superoxide dismutase(SOD)activity in test group Ⅱ of Pingliang red bull serum were significantly higher than those in the control group(P＜0.05),while the contents of triglyceride(TG)and malondialdehyde(MDA)were significantly lower than those in the control group(P＜0.05).3)The serum glucose(GLU)content in the test group Ⅱ was sig-nificantly lower than that in the control group(P＜0.05).In conclusion,the addition of 3.5 g/d CBet to the diet can improve the growth performance in late fattening period of Pingliang red bull,while the addition of 7.0 g/d CBet can improve the serum immunity,antioxidant,fat metabolism and energy metabolism.[Chinese Journal of Animal Nutrition,2024,36(4):2487-2496]
