Effects of cross inoculation of ruminal on dry matter digestibility and the rumen ecosystem

Results of the study showed that transferring ruminal content from buffalo to cattle reduced the pH value but increased ammonia concentration (alpha0.05) in the rumen. Similarly, there was a significant change in the total counts of bacteria and fungi, as well as in dry matter digestibility and effective degradability (alpha0.01) of napier grass, but not in those of legume and concentrate as substrates. The transfer of rumen content from cattle to buffalo decreased pH value (alpha0.05) and total counts of bacteria. There was a reduction (alpha0.05) in the dry matter digestibility of leucaena and wheat pollard. In study 2, the transfer of rumen content from goat to sheep increased (alpha0.05) ammonia concentration and total number of protozoa, but reduced (alpha 0.05) total number of bacteria. The dry matter degradability of napier grass and Leucaena was improved by the transfer of rumen contents from goat to sheep. The transfer of rumen content from sheep to goat resulted in a decrease (alpha0.05) of pH value and water intake, but increased ammonia concentration, total counts of protozoa and bacteria, dry matter degradability of napier grass, Leucaena and wheat pollard and improved (alpha0.05) intake of concentrate. Results of these studies indicate the potential of cross-inoculation of rumen content between ruminant species in altering the rumen ecosystem and fermentation of the ingesta
