Abstract

The microbial populations present in the rumen have high contribution in the digestion of organic matter and nutrient supply to the metabolism of the host animal.The interactions between microbial communities can be altered through nutritional strategies adopted, affecting the dynamics of ruminal fermentation and consequently animal performance. Currently the crude glycerin from the biodiesel industry has increased and its utilization has been made in substitution for cereal grains in the diet with reduced costs of the production system. The use of crude glycerine has also been combined with lipid sources. This nutritional strategy can increase the energy density of the diet and possibly reduce the process of lipolysis in the rumen with lower release of insatured fatty acids in the environment and reduction of biohydrogenation. But little is known about possible changes in ruminal microbiota and profile of dietary fatty acids. The objective of this study is to evaluate in vitro the changes in ruminal fementation and fatty acid profile of soybean oil and linseed oil with the inclusion of glycerol in a diet containing Tifton 85 hay (Cynodon spp.). The experimental design will be repeated measures with a factorial 2x2 (two levels of glycerol and two sources of oil).
