Abstract
Feeding highly fermentable carbohydrate resulted the huge amount volatile fatty acids (VFA) production especially lactic acid in un-adapted rumen. The role of rumen microbe on conversion of lactic acid to propionate is well documented. On the other hands, numerous studies have been determined the role of butyrate on the growth and development of rumen epithelium. In this manner, present study has been investigated the feeding of different levels of sodium butyrate in transition cows and its effects on lactic acid consumption by rumen fluid in the early of lactation. Twelve Holstein dry cows in the late of pregnancy divided into three groups with one group being fed 30 g (daily) of sodium butyrate mixed with wheat bran (T30) and the second group with 60 g (daily) of sodium butyrate mixed with wheat bran (T60) and the third group left without supplementation as a control (Cont). On days after parturition 10 ml rumen fluid was taken by ruminocentesis, and the ability of rumen fluid for lactic acid consumption was determined. The correlation between lactic acid concentration in rumen fluid and the ability of rumen fluid for lactic acid consumption was analyzed using the Bayesian approach, after correction for fixed effect (Na butyrate treatments). The results showed that no significant difference among treatments for lactic acid consumption. However, the 95% highest posterior density (HPD) interval of correlation between above parameters was found from -0.99 to -0.60. In view of the fact that zero value is out of this range, it can be concluded that the correlation (ó †°ρ=-0.84) is significant.
