Abstract

The aim of this study was to assess sperm quality (motility, viability and acrosomal integrity) sperm from commercially frozen semen straws two breeds of bulls Bos taurus (holstein Frisian) and Bos indicus (Brahman). 9 commercial straws 0.5 ml of Holstein bull semen and 9 Brahman bull were thawed, they were kept for two hours at room temperature and motility, viability and acrosomal integrity (NAR) was assessed. The results were 30% motility, viability 40% and 30% of NAR in the Holstein breed. Brahma race for motility 40%, 50% and 40% viability was obtained NAR. In conclusion, according to the results of the variables analyzed, the Brahman breed in sperm quality was better than the Holstein breed; however, the results of both races meet minimum standards of quality sperm for use in artificial insemination (AI) field level.

1. Introduction

The freeze-thaw process, affecting approximately 50% of the sperm survival, is mainly due to the effect of these processes on the membrane, motility and sperm nuclei. It is considered that the primary site of damage associated with temperature changes are the sperm membranes [1] . The reduced fertility associated with frozen- thawed semen was largely attributed to alteration of the structure and function of sperm membranes during the cooling process, freezing and thawing. For the sperm can fertilize the egg, must maintain their motility, viability and acrosomal membrane integrity [2] .

The main parameters to be measured in semen after thawing are motility, viability and acrosomal integrity [3] -[6] .

The aim of this study was to assess sperm quality (motility, viability and acrosomal integrity) sperm from commercially frozen semen straws two breeds of bulls Bos taurus (holstein frisian) and Bos indicus (Brahman).

2. Material and Methods

18 0.5 ml straws of bull semen, including 9 with semen from Holstein and 9 Brahman thawed. The straws with semen of both races were thawed in a water bath at 35˚C for 35 seconds, they are perfectly dried, uncovered and semen was deposited in tubes Ependorf to assess immediately after motility, viability and NAR [7] , semen thawed stored at room temperature for two hours and assessments were made every hour.

3. Results

The results obtained are shown in the following Table 1.

Table 1. Average percentages obtained valued variables.

NAR: acrosomal integrity.

4. Discussion

Sperm quality is measured through motility, viability and NAR, whose importance is reflected in the fertility of semen used in animal production unit.

In Holstein, an average of 30, 40 and 30 was obtained; Brahma in 40%, 50% and 40% motility, viability and NAR, respectively; These percentages were higher than those obtained by [8] , who noted that these percentages decreased of 10% - 15% within 2 hours of incubation and minimum standards for progressive motility were 25% at 0 hours and with temperature resistance of 15% at 2 hours [2] [3] [5] .

In conclusion, according to the results of the variables analyzed, the Brahman breed in sperm quality was better than the Holstein breed; however, the results of both races meet minimum standards of quality sperm for use in artificial insemination (AI) field level.
