Descripción

Analyses of cryopreserved semen batches are carried out using various technologies, including microscopy with sub-jective analysis and CASA (Computer-assisted semen analy- sis), focusing on different abilities of the sperm. The choice of semen for AI largely affects the final result. Thus, it was proposed to evaluate the applicability of fertility prediction models and the efficiency of two CASA (Hamilton Thorn IvosII, hCASA, and iSperm) and subjective analyses. Doses of cryopreserved semen from 15 bulls (Nelore and Angus) used in fixed time artificial insemination (FTAI) were analyzed.
