Abstract:
This study aimed to investigate the impact of FMD vaccination on seminal parameters at the Germ Plasm Centre (GPC), ICAR-IVRI, India. Three Vrindavani breeding bulls selected were subjected to the same feeding and management practices. Six ejaculates (3*2) were collected from each bull, with the first collection occurring one week before vaccination and the subsequent collections spanning six weeks after vaccination with the RAKSHA-OVAC TRIVALENT FMD vaccine (concentrated) using an oil adjuvant from Indian Immunological Ltd. Seminal quality parameters, including ejaculate volume (ml), sperm concentration million/ml), viability (%), and sperm abnormalities (%), were meticulously assessed for all ejaculates. The data from the ejaculates were subjected to statistical analysis, which involved calculating descriptive statistics such as mean values and standard errors, along with a one-way analysis of variance. Mean comparisons were conducted using Fisher pairwise comparison at a 5% significance level. The results indicated that the impact of FMD vaccination on these parameters was statistically significant (p<0.05) when compared to both the pre-vaccination and the first-week post-vaccination periods. Notably, the volume of semen per ejaculate remained relatively consistent, suggesting that it was not significantly affected by the Foot and Mouth Disease (FMD) vaccination, in contrast to the significant effects observed on sperm concentration, viability, and sperm abnormalities (p<0.05).
