菌草菌糟作为饲料在奶牛饲养中的应用效果
Application effect of Juncao spent mushroom substrate as a feed in the dairy farming
摘要
Abstract
Selecting 15 Holstein dairy cows with basically the same age, weight, parity, lactation and milk yield, randomly divided into two test groups and a control group. Group 1 per head per day were added spent Pleurotus eryngii substrate 2 kg, instead of beet pulp 1.5 kg, other diets were the same with control group. Group 2 were added spent P. eryngii substrate 1 kg to the basal diet. The dairy cows in control group were fed with conventional basal diet. The milk yield, milk quality, milk immunoglobulin G, the impact of cow immunoglobulin G and immunoglobulin M levels were studied during the experiment, at last economical benefits analysis was made. The results showed that the milk yield of control group and group 1 decreased 8.21% , 3.72% respectively than that before the test, the milk yield of group 2 increased 1.21%. It indicated that replacing beet pulp with spent P. eryngii substrate or adding spent P. eryngii substrate directly to the basal diet could slow the downward trend of the mid-lactation milk yield. The quality of milk, blood urea nitrogen, total protein, albumin, blood glucose, cholesterol, alanine aminotransferase of experimental group had no significant impact (P>0.05). IgG contents in the milk of the experimental group 1 and 2 were 0.59 and 0.09 g · L-1 higher than that of the control group, but no significant difference. IgM levels of group 1 were 0.12 g · L-1 higher than that of the control group, the difference was significant (P <0.05). Economic analysis showed that compared with the control group, the experimental group could increase the income by 197.66 and 244.27 yuan per month respectively.关键词
