Breeders in developing countries, particularly Malaysia, are embracing the advantages of using artificial insemination (AI) to produce crossbred progeny with better beef and milk production. This genetic composition of superior bulls helps in improving the product quality of the cattle population in Malaysia. National Institute of Veterinary Biodiversity (IBVK) is an institute that is responsible for supplying high quality bull semen for breeders. This paper provides an overview of bacteriological control in bull semen practiced by IBVK including the process of semen collection, handling, and storage of semen. The implementation of microbiological control is important because it represents the hygiene status of semen. The transmission of infectious disease can cause clinical effects on recipients, decrease productivity, and influence fertility. Furthermore, bacterial contamination in bull semen can also deteriorate sperm quality. Preliminary data were collected from the Department of Veterinary Services (DVS) system, Sistem Maklumat Makmal (SIMMAK) data. The result of this study found that only 0.5 % bacterial contamination was detected from 2018 until 2021 indicating that good hygiene procedures were used during semen collection, which correlate with sperm function and parameters. This study serves as a baseline for more extensive research to better control bacterial contamination in bull semen in future and contributes to the updated information on bull semen processing conducted in IBVK.

Abstract

Breeders in developing countries, particularly Malaysia, are embracing the advantages of using artificial insemination (AI) to produce crossbred progeny with better beef and milk production. This genetic composition of superior bulls helps in improving the product quality of the cattle population in Malaysia. National Institute of Veterinary Biodiversity (IBVK) is an institute that is responsible for supplying high quality bull semen for breeders. This paper provides an overview of bacteriological control in bull semen practiced by IBVK including the process of semen collection, handling, and storage of semen. The implementation of microbiological control is important because it represents the hygiene status of semen. The transmission of infectious disease can cause clinical effects on recipients, decrease productivity, and influence fertility. Furthermore, bacterial contamination in bull semen can also deteriorate sperm quality. Preliminary data were collected from the Department of Veterinary Services (DVS) system, Sistem Maklumat Makmal (SIMMAK) data. The result of this study found that only 0.5 % bacterial contamination was detected from 2018 until 2021 indicating that good hygiene procedures were used during semen collection, which correlate with sperm function and parameters. This study serves as a baseline for more extensive research to better control bacterial contamination in bull semen in future and contributes to the updated information on bull semen processing conducted in IBVK.
