Use of ultrasound in sows SUBJECT TO Natural mating or artificial insemination

Abstract

The reproductive performance is of great importance in the economic efficiency of pig activity. Within this context, the modern pig farming has great advances in reproductive highlighting the use of artificial insemination, natural mating, and even controlled the early diagnosis of pregnancy by ultrasound. This study aimed to use ultrasound in the diagnosis of pregnancy of sows, determining the best period for its implementation, and evaluate the reproductive efficiency in the use of artificial insemination and natural mating. Were carried out ultrasound scans in both transabdominais antimere of each animal. The minimum period of gestation of sows for diagnosis performed by ultrasound was 20 days, showing to be a quick look, high accuracy and can be used as an auxiliary method to improve reproductive efficiency in this species.
