Evaluation of application effect of microbial fermentation bed and traditional sheep raising mode in winter
The purpose of this experiment was to investigate the effects of microecological fermentation beds on lambs in winter and to compare them with traditional sheep rearing models.The experiment was divided into three batches.Each batch selected 30 ewe who had just given birth and were randomly assigned to a closed sheep house with windows facing the same building structure.The ground of one group was transformed into a microbial fermentation bed(experimental group),and the other group was used as the control group with 15 ewe in each group.The experimental period of each batch was 45 days,and the interval between the two batches was 45 days.The results showed that the fermentation bed surface temperature of experimental group was extremely higher than that of control group(P<0.01).The average lying ratio of lambs in experimental group was higher than that in control group,and the average standing ratio was lower than that in control group.Compared with the control group,the diarrhea rate of lambs in the experimental group was reduced by 66.02%,and the survival rate was increased by 6.37%.The weaning weight and average daily gain of lambs in experimental group were significantly higher than those in control group(P<0.05).Compared with the control group,the contents of serum total protein(TP)and albumin(ALB)in experimental group were increased by 3.48%and 4.41%(P<0.05),and the contents of globulin(GLB)and glucose(GLU)in experimental group were increased by 5.51%and 7.41%(P>0.05),respectively.Compared with the control group,the serum immunoglobulin G(IgG)content of experimental group was increased by 12.94(P<0.05).Studies have shown that the use of micro-ecological fermentation bed feeding can reduce the diarrhea rate of lambs,promote lying down,increase the weight gain of lambs before weaning,improve the serum biochemical indexes of lambs,improve immunity,and contribute to the healthy growth of lambs.
