Effects of Different Concentrate to Forage Ratio on Growth Performance,Blood Biochemistry and Rumen Microbial Diversity of Leizhou Goats
摘要
Abstract
[Objective] The effect of different proportions of fine fodder and roughage diet on barn feeding leizhou goats production performance,blood biochemical indices and the rumen microflora were studied.[Method] 24 healthy male and female leizhou goats with similar weight[(10.94 ±0.67) kg] were used.Male and female of 6 months of age were assigned randomly to 4 treatment groups with 6 replicates.The control group D0 was supplemented with Pennisetum hydridum.Group D10,D20,D30 were supplemented with Pennisetum hydridum (dry matter basis) for 10 ∶ 90,20 ∶80,and 30 ∶ 70 mixed fodder respectively.The blood samples and the gastric juice of the goats were collected.The blood physiological indexes and the microbial diversity of rumen were measured.[Result] The Group D10,D20 and D30 average daily gain were 33.28 g and 82.58 g and 81.80 g/d respectively which were 111.97％,425.99％ and 421.02％ higher than that of the DO group(P ＜ 0.05).The total numbers of white blood cells of the treatment groups were less than the control group (P ＞0.05).Treatment groups' total number of red blood cells,hemoglobin,red blood cell osmatic pressure were higher than the control group.The D20 group were significantly higher than that of control group (P ＜ 0.05).There was no significant influence on the diversity of the rumen bacteria of the Leizhou goats (P ＞ 0.05).[Conclusion] The 20 ∶ 80 proportion of fine fodder and roughage can reduce the total number of white blood cells and Leizhou goats' daily gain,total number of red blood cells,hemoglobin and red blood cells deposited were significantly improved.Under this experimental condition,barn feeding Leizhou goats' suitable proportion of fine fodder and roughage was 20∶80.关键词
