Perspectives of intrauterine artificial insemination applicability in gilts

ABSTRACT: The application of the intrauterine artificial insemination (IUAI) technique allows optimization a swine production system due to reductions in volume and number sperm cells dose, by reducing time taken perform insemination. However, IUAI is not recommended for gilts difficulty cannula passage through cervix. This associated mainly with fact that reproductive tract smaller than pluriparous females. few studies have evaluated gilts. In these studies, there are variations approach concerning definition success rate cervix, type body characteristics used, making it difficult extrapolate recommendation use Considering evidence such influence or even determine IUAI, necessity an understanding factors improvement later technique. Gilts represent about 15-20% breeding group, could optimize processes on farms. used this review highlights aspects aid structuring further improving gilts, allowing its commercial
