Abstract

This study aimed to assess characteristics of bovine cryopreserved sperm and evaluate its relation to field fertility in fixed-time artificial insemination (FTAI). Semen samples of 16 bulls were used to inseminate 811 Nellore cows, and four of these bulls were also used to inseminate 101 Nellore...

Abstract

Mammalian sperm are exposed to a natural hypoosmotic environment during male-to-female reproductive tract transition; although this activates sperm motility in vivo, excessive swelling can harm sperm structure and function. Aquaporins (AQPs) is a family of membrane-channel proteins implicated in...

Abstract

Little is known of the genetic variability in semen quality traits in cattle and their inter-relationships. The objective of the present study was to estimate genetic parameters for a range of semen quality measures. The data consisted of 35,573 ejaculates from 787 artificial insemination bulls of...

Abstract

The number of doses per pregnancy gives an indication of the fertility of the cow, the quality of semen and insemination. Therefore, the goal of this study was to investigate the relationship between the physical and morphological assessment of semen cryopreserved in Central with the number of...

Abstract

Success of artificial insemination in bovine industry depends upon quality of frozen-thawed semen. Therefore, proper analysis of the post-thaw semen can provide insights into the fertilizing capacity of the cryopreserved semen. Frozen-thawed semen of 14 cross-bred and 12 pure-bred bulls was...

Abstract

This paper aimed at investigating the potential use of sperm DNA fragmentation (SDF) to improve the routine screening of infertility of Holstein bulls. Cryopreserved sperm samples from 201 Holstein bulls provided by an AI center were used in the analyses of SDF at 0 (SDF_0) and 6 (SDF_6) h of...

Abstract

The aim of the present study was to demonstrate the relationship between short- and long-thawing procedures and post-thawing thermal conditions. Semen samples of 4 Holstein bulls, frozen in straws of 0.25 ml, were used. Straws were thawed in water baths at 37°C using two different thawing...

Abstract

Two experiments were conducted to compare the effectiveness of different extenders conventionally used for semen cryopreservation to maintain the viability and fertility of cooled bull semen. In Experiment 1, sperm samples obtained from 20 Nellore bulls were preserved at 5°C for 48 h using two...
