ANDROLOGICAL POINTS CLASSIFICATION AND ANDROLOGICAL REPRODUCTIVE EVALUATION CHARACTERISTICS IN GIR BULLS CANDIDATES FOR PROGENIETEST

Authors

Abstract

Reproductive efficiency should be evaluated in dairy farms, when they are related to reproductive problems in both female and male. Breeding is among factors that affect herd productivity and draws attention by low rates of traditional livestock breeding. The aim was to study sperm evaluation tool known as the CAP index and its correlation with the biometric and morphological analyzes of Gir bulls semen. Thirty four healthy Gir bulls (Bos taurus indicus), dairy fitness, with 17 to 31 months of age with 450 kg of body mass were used. The bulls were submitted to andrological examination (physical evaluation including testicular biometry and semen morphological analysis) follow by andrological classification by points (CAP index). Three independent collections were carried out to evaluate sperm quality per bull during the experiment period According to the CAP index, animals were classified as excellent (17%) and as very good (83%). The CAP Index correlated positively with scrotal perimeter and semen physical characteristics.
