CARACTERIZAÇÃO DE PROTOZOÁRIOS RUMINAIS DE OVINOS ALIMENTADOS COM MILHO E MILHETO

Abstract

The objective of this study aims to characterize the rumen protozoa population of ½ Dorper and ½ Santa Inês sheep fed with different concentrations of corn and millet (100%, 75%, 50%, 25% and 0%) in the concentrate. The experiment was carried out at the sheep goat laboratory of the Federal Institute Goiano – Campus Ceres. Ruminal fluid samples were extracted from 25 lambs, being taken out 1mL of each sample were removed, diluted in test tubes with 9ml of 10% formaldehyde, and quantification and identification of protozoa were performed. There was a prevalence of small and medium size protozoa. The genus Entodinium, Diplodinium, Eudiplodinium and Eodinium were identified, being Entodinium the most frequent. Diet with 100% corn promoted protozoa defaunation, the protozoa concentration per mL ranged from 102 to 105 and was below normal. The diet with 100% millet is indicated because the greater diversity of protozoa.
