The effect of age on semen freezability of Swamp Buffalo bull in a commercial artificial insemination center

Abstract

This study aimed to assess the effect of age on semen freezability (sperms motility before freezing, post-thawing, recovery rate, and straws production per ejaculate) of swamp buffalo bull kept in Lembang Artificial Insemination Center. A total of 115 ejaculates collected from one swamp buffalo bull at 5, 6 and 7 years old were included in the study. The results showed that the overall mean values of sperms motility before freezing, post-thawing, recovery rate, and straws production per ejaculate of swamp buffalo bull were 62.13%, 43.61%, 62.16%, and 114.16 doses, respectively. The age of bull did not show significant (P>0.05) effect on sperms motility before freezing, however the sperms motility post-thawing, recovery rate, and straws production per ejaculate was influenced (P<0.01) by bull age. At seven years old, the poorest (P<0.01) post-thawing sperms motility and recovery rate were noted in comparison to 5 and 6 years old, nevertheless the difference in post-thawing sperms motility was only less than 3% point, which was not biologically important. On the other hand, the semen collection at seven years old had a higher (P<0.01) straws production per ejaculate than those at 5 and 6 years old (133.70 vs. 106.39 and 90.61 doses, respectively). In conclusion, this study provides evidence that the semen freezability of swamp buffalo bull is varied among the age with the peak frozen semen production was achieved at seven years old.

Effect of breeds on semen characteristics of aged bulls in the Indonesian National Artificial Insemination Center

“…However, statistically no difference between the semen volumes of Madura and Bali bulls.Breed had a highly significant effect on semen volume, which is consistent with the studies of Isnaini et al, (2019), Koivisto et al, (2009), andField et al, (1979), who also reported a similar result. This significant effect could be associated with the differences in scrotal circumference (SC) among different breeds (Siddiqui et al, 2008).…”

“…This result had different patterns concerning semen volumes. However, this finding is in contrast to a previous study conducted by Isnaini et al (2019), who found that Simmental cattle had a higher sperm concentration than Bali cattle. Nevertheless, this difference might be the result of the different ages of bulls in the study.Base on cattle's age, some studies examined the effect of age on bull concentration.…”

Kualitas spermatozoa post-thawing pejantan sapi Friesian Holstein pada umur yang berbeda

“…Pada sapi pejantan Jersey volume ejakulat, konsentrasi spermatozoa, viabilitas, normalitas morfologi, motilitas spermatozoa pada semen segar, pre-filling, dan motilitas post-thawing, lebih tinggi pada sapi pejantan berumur 5-7 tahun dibandingkan usia yang lebih muda maupun yang lebih tua (Sankhi et al, 2018). Pada sapi pejantan Simmental tua (umur 12 tahun atau lebih) ejakulat mencapai volume tertinggi, tetapi konsentrasi spermatozoa, jumlah spermatozoa total, motilitas postthawing rendah sehingga dosis semen beku juga rendah (Isnaini et al, 2019).…”

An Investigative Immunoassay Targeting Two Osteopontin Epitopes in Boar Semen

“…The ultimate aim of any pig breeding programme is to increase the profitability of commercial pork production. Artificial insemination practices dominate reproduction management on pig farms in South Africa because it brings superior sire lines into the herd and across many sows [1]. The identification of superior sire is largely dependent on the semen quality evaluations and the reproductive performance of sires [2].…”
