Abstract

This experiment was conducted to investigate the effects of different doses of compound enzyme preparation on rumen fermentation, apparent digestibility of nutrients, serum biochemical indices and performance of lactating cows. Thirty-two healthy Holstein lactating cows were selected with similar body weight, parity, lactation days and milk yield. The cows were allocated to 4 groups according to a randomized blocks experiment design. Dairy cows in control group were fed a basal diet, while those in trial groups were fed the basal diet with 0.10%, 0.15% and 0.20% compound enzyme preparation, respectively. Preliminary trial period was 10 days, and formal trial period was 56 days. The results showed as follows:1) compared with the control group, adding 0.15% compound enzyme preparation in the diets significantly increased total volatile fatty acids content of rumen fluid (P<0.05) and adding compound enzyme preparation had a trend to increase acetic acid content (P=0.08), but had no significant effects on other volatile fatty acids, ammonia nitrogen and micro protein contents (P>0.05). 2) Compared with the control group, adding compound enzyme preparation in the diets significantly increased the apparent digestibility of dry matter and neutral detergent fiber (P<0.05), and adding 0.20% compound enzyme preparation significantly increased the apparent digestibility of organic matter (P<0.05). 3) Compared with the control group, adding compound enzyme preparation in the diets had a trend to increase serum albumin content (P=0.09) and decrease urea nitrogen content (P=0.07), but had no significant effects on other serum biochemical indexes (P>0.05). 4) Compared with the control group, adding 0.10% and 0.15% compound enzyme preparation in the diets significantly increased feed conversion rate (P<0.05), and the 3.5% milk fat correction milk yield in 0.10% and 0.15% groups was increased by 3.88 and 4.27 kg/d (P<0.05), respectively. The milk fat rate in 0.15% group was increased by 12.70% (P<0.05). In conclusion, adding compound enzyme preparation in the diets can improve feed conversion rate, rumen fermentation and performance. Comprehensive consideration, the recommended adding amount of compound enzyme preparation in the diets of lactating cows is 0.15%.
