EFFECT OF SYNCHRONIZATION OF CARBOHYDRATE AND PROTEIN SUPPLY IN THE SUGARCANE BAGASSE BASED DIET ON MICROBIAL PROTEIN SYNTHESIS IN SHEEP
Abstract: The experimental
research was conducted to clarify the effect of synchronization of ruminal
carbohydrate and protein releases from sugarcane bagasse based diet (SBBD) on
microbial protein synthesis in sheep. The first experiment was the formulation
of three SBBD with similar nutrient content but differed in synchronization
indexes (namely 0.36; 0.50 and 0.63). The in sacco nutrient degradability
coefficient was used to calculate the synchronization index of each feedstuff.
The second experiment was determination of post feeding ruminal pH, ruminal
concentrations of total volatile fatty acids (TVFA) and ammonia nitrogen
(NH3-N), and blood urea nitrogen (BUN) level in sheep fed on experimental SBBD.
The third experiment was determination of feed digestibility and estimation of
microbial nitrogen synthesis (MNP) on the basis of excreted urinary allantoin.
The alteration of dietary synchronization index did not change nutrient intake,
but the digestibilities of DM, OM and CP were increased (P<0.05). The post
feeding ruminal pH was decreased (P<0.05) but concentrations of post feeding
ruminal TVFA and NH3-N, and level of BUN were increased (P<0.05) by the
treatment of dietary synchronization index. The treatment of dietary
synchronization index improved MNP (P<0.05), although dietary
synchronization index at 0.63 lowered the MNP (P<0.05).
