Influência de informações genética e fenotípica no preço em leilões de fêmeas da raça Girolando

Abstract

The type of auction on which the animals were marketed and the English Auction. There are still not many studies in Brazil that correlate with genetic and phenotypic information. This study aims to verify the influence of genetic and phenotypic information on the auction price of female animals of the Girolando breed at the auctions held during the Brazilian Agribusiness Exposure of milk, Mega Leite 2017 in Belo Horizonte. As information about the participation in several auctions of the breed, these being of face-to-face modality not farpante of the Gameleira Park in Belo Horizonte / MG. It was considered significant when P ≤ 0.05. There was no association between the predicted transmission capacity (PTA) and the marketing price. Females Generators of ½ H genetic composition were more valued in relation to females of genetic composition ¾ H. Renowned crimson and with greater time of selection add higher average without price of commercialization, production of in vitro embryos (IVP) and a factor considered by the breeders and allowed greater appreciation of females. As daughters of bulls, they perform as having the highest sales figures. There was no significant difference in the age groups from 36 to 46 months,> 48 months and 24 to 36 months. However, animals from 36 to 46 months were better marketed on average than animals ≤ 12 months and 12 to 24 months. Clear castor bean animals were on average more valued in castor bean animals in black. Then, it was verified that all variables studied, except predicted transmission capacity (PTA), had an influence on the average selling price of the animals during Mega Leite 2017.
