Abstract

In order to characterize microbial populations and fermentation indicators of fattening in Charolais cattle from Cuba four bulls in the ending of the fattening stage were used, which were under the Pennisetum purpureum cv. Cuba CT-115 grazing regime. For fulfilling the study ruminal fluid was extracted using a esophageal tube. Results were analyzed with STATGRAPHICS computer program to obtain the mean and standard deviation of the analyzed indicators. A total of 26.67 x1010 cfu mL-1 of viable bacteria population was found, as well as 46.38 x108 cfumL-1 of methanogenic bacteria. The pH of the ruminal fluid was 7.75 and the concentrations of NH3 and total SCFA were 7.75 meq L-1 and 83.44 mmol L-1, respectively. It can be concluded that the microbial populations and the fermentative indicators are among the expected ranges for ruminants fed with fibrous diets as their only source of food. More comprehensive studies that contribute to deepen the knowledge about the ruminal fermentation in this breed are suggested.
Key words: Ruminant indicator, charolais cattle, Pennisetum purpureum
