Perdas perinatais em éguas da raça crioula

Abstract

The horse of the Criollo breed is an individual of medium height and adapted to the region in which it was developed. In other words, it is a rustic breed used both for rural work as well for competitions. However, with the growth of the race, the selection directed to athletic performance and conformation has brought changes to the quality of the reproductive Creole mare. The growing expansion of the market of this race, and a significant valorization of the specimens, motivates breeders to study the best ways to improve its creation aiming to obtain positive economic results. In order to study the perinatal losses, which also causes economic losses, work was undertaken collecting data with breeders and veterinarians linked to this race, with the main objective to study the main causes and ways to prevent these losses. The study found out that 100% of farmers and 70% of veterinarians replied that the births take place in the field, i.e., differently from other breeds such as the Racing Thoroughbred, where many births are assisted. There is a great tendency to significantly increase the use of artificial insemination in mares of Criollo breed , since this tool was shortly adopted by ABCCC and there is already a large number of breeders who use it, thus reducing the use of controlled mounts and field mounts. The vast majority of losses occur because of abortion, and leptospirosis is characterized as the main cause. The preventive managements are still not satisfactory, but there is a concernment of breeders and veterinarians with the deploying of techniques that may minimize these problems.
