PROTOZOÁRIOS RUMINAIS DE VACAS NELORE RECEBENDO SUPLEMENTAÇÃO MINERAL OU PROTEICO-ENERGÉTICA NA ESTAÇÃO DAS ÁGUAS

Abstract

The objective of this work was to verify the effect of supplementation in waves on the population of protozoa in the country, characterizing as the main populations of protozoa in the rumen. Until the moment the animals were found, the experiment was carried out briefly by the Universidade Estadual Paulista Júsquita Filho (UNESP), in partnership with IF Goiano Camps. After that, 15 ml of rumen fluid was collected from the rumen region with the aid of a tube, and slaughter was scheduled for the microbiology laboratory of Campus IF Goiano Ceres. For quantification, a Sed-Rafter camera was used, the light of the optical lugol, using an 11-point objective, and for identification, a slide and coverslip with the addition of a drop of light was used. Data were conducted for exploratory data analysis exploratory data and data substantiation, using Spearman. The populations of small 0-70 µm (70-140 µm) and medium (140-210 µm) protozoa do not show statistical differences regarding the type of supplementation. The amount of small (0-70 µm) protozoa was higher than the medium (70-140 µm) and large (140-210 µm) protozoa, especially the genus Entodinium, which was frequently found. The main and suitable protozoan populations for the small, medium, large and similar variables. The use of protein-energy mineral supplements does not promote protozoa similar to the environment of ruminal cows.
