Foot and Mouth Disease (FMD) is a significant concern in livestock management, necessitating effective vaccination programs to protect cattle. Bali cattle, an important breed in Indonesia, are no exception. A recent study conducted by researchers from the National Artificial Insemination Centre (NAIC) in Singosari and Universitas Airlangga in Surabaya sought to determine whether FMD vaccination affects the basic semen quality parameters in Bali cattle bulls.
The study focused on 25 Bali cattle bulls at the NAIC in Singosari. Researchers collected semen samples both before and after the bulls were vaccinated against FMD. The study analyzed various semen quality parameters, including individual motility, abnormality percentage, spermatozoa concentration, and semen volume. To compare the results from pre- and post-vaccination groups, a paired sample t-test was performed.
The statistical analysis revealed no significant differences in any of the semen quality parameters before and after vaccination:
Individual Motility: The ability of sperm to move effectively is crucial for fertilization. The study found no significant change in sperm motility after vaccination (t(74) = -1.72, p = 0.95).
Abnormality Percentage: Healthy sperm morphology is vital for successful reproduction. There was no significant increase in sperm abnormalities post-vaccination (t(74) = 2.06, p = 0.98).
Spermatozoa Concentration: A higher concentration of sperm cells typically indicates better fertility. The study showed no significant difference in sperm concentration after vaccination (t(74) = -4.35, p = 1.00).
Semen Volume: The volume of semen produced is another indicator of reproductive health. No significant change in semen volume was observed post-vaccination (t(74) = -0.11, p = 0.54).
The study concluded that the FMD vaccination program for Bali cattle bulls does not negatively impact the basic semen quality parameters. This finding is crucial for livestock managers and breeders, ensuring that vaccination protocols can be followed without compromising semen quality for frozen semen production.
These results provide reassurance to cattle farmers and breeders about the safety and efficacy of FMD vaccination programs. Ensuring high-quality semen is essential for artificial insemination and the continued improvement of cattle breeds. With FMD being a persistent threat, maintaining robust vaccination programs is vital for the health and productivity of livestock.
Future research could explore the long-term effects of FMD vaccination on reproductive health and investigate other factors that may influence semen quality. However, this study provides a strong foundation for understanding the immediate impact of FMD vaccination on Bali cattle semen quality.
