A RELAÇÃO DO ESCORE DE CONDIÇÃO CORPORAL NA QUALIDADE DE OVÓCITO E TAMANHO DE DIÂMETRO FOLICULAR EM VACAS SRD.

Abstract

The physical condition of the animal has a significant influence on the overall body physiology, therefore, we can say that nutrition is directly linked with the playback. A practical and simple way to evaluate the physical condition of cattle is through the scoring method of corporal condition (ECC) which you can help identify a general form, problems related to nutrition that may be affecting the flock and reducing productivity. In view of the exposed cows with good ECC would produce follicular diameters larger and a better quality of oocyte. Therefore the objective of this work was to equate the interaction between the parameters: ECC, quality of the oocyte and follicular diameter in crossbred cows.To this end were used 50 crossbred cows, which were classified according to their ECC, being then collected their respective ovaries, forwarded to the laboratory where they were analyzed in terms of quantity of the follicles and measured their diameters. Soon followed the same were aspirated and observed in Magnifying Glass estereomicroscópica for quality classification of oocyte of agreement with the cells of Mr Raffarin. It was observed that cows with ECC 2 present a greater quantity of quality of oocyte Grade 3, cows with ECC 3 presented a greater quantity of quality of oocyte Grade 1, and cows with ECC 4 present a greater quantity of oocyte quality grade 1. In relation to the diameters of follicles, the animals that received the largest index of follicles with diameter ≥ 1cm were animals with ECC 2, in the right ovary, and animals with ECC 3, in left ovary.
