Abstract
In a study to see the effects of Saccharomyces cerevisiae SC Asperigillus oryzae AO and non-ionic surfactant NIS on the DMI BCS and performance of lactating cows 40 pregnant Holstein dairy cows were divided into 4 groups by parity and milk production of their previous lactation lactation number live weight and BCS. Within each group 10 cows in the transition period were randomly allocated to the control SC AO and NIS supplemented TMR total mixed ration. Daily milk production for 42d post-partum was not affevted in contrast to 4 FCM production was significantly P0.05 affected by the supplementation of SC AO or NIS due to the significant treatment differences of fat components. The production of FCM by the cows fed TMR supplemented with SC AO and NIS was 21.32 11.53 and 9.26 higher than those fed control TMR. Efficiency of feed utilization for milk production was significantly P0.05 improved by the supplementation of all additives tested especially by NIS. These results showed that NIS might be of use as an alternative feed additive such as SC or AO to improve the performances of dairy cows.
