Impacto do peso corporal e ganho de peso como critérios de julgamento de ovinos Dorper e White Dorper em exposições agropecuárias

Abstract

The objective of this study was to compare weights of sheep from different age categories in a farm with average weights of winner animals of livestock show and also with an average of each category of the judgment show to verify the impact of the weight criteria as a determinant factor on animal judgment. Data from 84 animals from the Dorper Campo Verde farm (DCV) and 309 animals from the exhibition were collected. The Tukey's test was used to compare the means of weight and weight gain. For the entire population studied, as expected, we observed a significant difference for the sex factor, in which average weight, as well as the weight gain of the males were superior to those of the females. It was also not observed any statistical differences between the Dorper and White Dorper DCV animals, the 2008 and the 2018 exhibition animals. Neither it was found any statistical differences between the 2018 winner exhibition animals and the DCV ones. The weight gain parameters, as well as the average live weight of the animals are not determinant factors, within each age range, nor do they configure themselves as an advantage for the first classification in these types of events.
