Effects of Malate and Yeast Level in Concentrate Containing High Cassava Chip on Ruminal Fermentation and Digestibility of Nutrients in Dairy Heifers
MetadataShow full item record
The objective of this study was to determine the effects of malate level and yeast in concentrate on ruminal fermentation and digestibility of nutrients in heifers. The results revealed that rumen fermentation, ruminal microorganisms and digestibility of nutrients were significantly different (P<0.05) as affected by malate level and yeast. In conclusion, the combined use of concentrate containing high level of cassava chip at 70%DM with malate at 1,000 g and yeast at 2,000 g in concentrate could improve rumen fermentation and digestibility of nutrients in dairy heifers.
