Extract

The microbial protein synthesis is variable and depend of several of factors, one the most important being the energy sources. Numerous investigations have evaluated individual sugars. However, few quantitative information is available describing the impact of sucrose or its monosacharides (glucose and fructose) and how they compare with other carbohydrate such as starch (Heldt et al., 1999). Chamberlain and Choung (1995) mention that sugar supplementation results in a higher microbial nitrogen supply (MNS) than starch. On the other hand, the amount of nutrients that ruminants can remove from feeds, may be modified by others feeds eaten the same day (Gill and Powell, 1993). Thus, feeding pattern might also affect microbial-N supply (Chamberlain and Choung, 1995). Therefore, the objective of the present work was to compare maize and sugarcane molasses as energy sources as well as the change of feeding pattern (CFP) on DM intake and MNS.
