Influence of body condition score (CCS) on structures ovarian of zebu cows submitted to artificial insemination in fixed time (IATF) in western Paraná

Abstract

The reproductive performace of cattle is directly related to their feeding, in Brazil cattle are raised mostly extensively, where adequate management of pastures is not carried out, being common overcrowding of animals and seasons of drought, resulting in low fertility of the animals. Therefore, reproduction in the species is negatively affected, because CCS is one of the factors that directly influence their cyclicality, where it is of paramount importance to adequate food and management that contribute to maintaining better CCS of animals at the beginning of the reproductive season, improving the indexes mainly at the beginning of the season. The objective of this study was to evaluate the animals the ovarian structure present in (D0) of the IATF and thus relate the data obtained with their body condition score (CCS), verifying whether the CCS influenced the structures found. In addition, 17 animals presented with ECC ≤ 3, 41 animals with ECC > 3 and < 4 and 42 animals with ECC ≥, while animals with corpus luteum (LC), presented with body score >3, totaling 89% of the animals and the other structures showed no difference between the CCS. Thus, the body condition of animals is one of the factors that influence the ovarian structure of animals.
