Fertilidade do sêmen congelado/descongelado e, posteriormente, rediluído em acp-102 em ovinos de corte exploradas em sistema de criação semi-intensivo / Fertility of frozen / thawed semen and subsequently rediluted in ACP-102® sheep sectional operated in semiintensive farming system

ABSTRACT

The objective of this study was the evaluation of the frozen and thawed semen fertility in ACP-102®.For this, 37 ewes were used, previously evaluated and considered clinically and reproducibly fit according toCBRA standards. The semen used was also evaluated according to CBRA standards (2013). After beingcollected, the semen was frozen in a TK 3000® seminal freezing machine. After thawing, half of the sampleswere re-diluted in ACP-102®, each vial in a 1 ml aliquot of ACP, and then the animals were inseminated indifferent ways, laparoscopic and transcervical. The group of animals submitted to insemination with semen redilutedin ACP-102® demonstrated a fertility rate on the 60-day ultrasound examination greater than the groupinseminated with Tris-Gem alone. No significant differences were found between insemination techniquesregarding fertility.(AU)
