Book Description
The present study has been undertaken to estimate volatile falty acids (VFA) production rates on one hand and bacterial production rates on the other in the rumen of buffalo calves given different levels of energy and protein to facilitate maximum fermentative rates and protein synthesis. The results indicated that there was no beneficial effect on bacterial protein synthesis by administerring extra protein in the diet than that recommended by NRC (1971). The bacterial protein synthesis was lowered when 40% of the DCP requirements by the animals was replaced with urea and high energy ration containign oil. At the same time maximum bacterial protein synthesis was observed when the animals were offered a ration of 100% DCP and 120% TDN. It was also observed that when 40% of the DCP requirement of the animals was met by feeding urea the effeciency of N-conversion into microbial protein was considerably reduced. It was found attributed to oil which was used as a source of energy which cannot contribute much towards the acceleration of microbial protein synthesis. It was pertinent to note that oil was not a suitable source for increasing the energy density of the diet as it primarily and adversely affects the consumption of various nutrients and digestibility of crude fibre which was an important source of energy at the cellular level and there by exerts a sparing action on the VFA'S produced in the rumen which influence the microbial protein synthesis favourably though to a limited extent.
