| description | This study aimed to evaluate the effect of newly developed compound probiotics on milk production, rumen fermentation characteristics and serum anti-stress parameters of heat-stressed dairy cows. Forty-five late-lactation dairy cows were randomly allocated into three groups, including control group (basal total mixed ration, TMR), compound probiotics (CP) group (20 g/d compound probiotics per cow in TMR) and yeast culture (YC) group (100 g/d yeast culture per cow in TMR). The results indicated that the compound probiotics and yeast culture increased milk yield significantly (P=0.03) with no influence on milk content, and improved ammonia nitrogen and microbial protein concentrations in rumen fluid (P=0.04) with no influence on volatile fatty acid concentration. The compound probiotics and yeast culture enhanced the apparent digestibility of crude protein and neutral detergent fiber (P<0.05), and a better performance was observed in the compound probiotic groups. The compound probiotics and yeast culture increased serum triiodothyronine (T<sub>3</sub>) content significantly (P<0.01). Thus, the compound probiotics could alleviate the negative effect of heat stress on dairy cows, and perform better than the yeast culture. |
