To assess the effect of Thuja (Thuja occidentalis) and Levamisole on the spermiogram of FMD vaccinated crossbred bulls, 24 adult Frieswal (Holstein × Sahiwal) bulls were divided into four groups viz. GC (control; no vaccination), GV (vaccinated), GL (vaccinated + Levamisole) and GH (vaccinated + Thuja). The bulls of GV, GL and GH groups were vaccinated with FMD vaccine. Four injections of levamisole were administered to the bulls of GL group at weekly interval starting from one week prior to the FMD vaccination. Homoeopathy medicine (Thuja) was given orally to the bulls of GH group consecutively on four days (on 4, 3, 2 & 1 day, respectively) before FMD vaccination. Average rectal temperature in vaccinated bulls increased significantly than in non-vaccinated bulls after 24 hrs of FMD vaccination. In GH, it was similar to GC in 36 h, however, became normal in all groups in 48 h of vaccination. Average VAP and VSL values were higher (p<0.05) in GC than in the other groups. Bulls of GH had higher (p<0.05) initial sperm subjective and CASA progressive motility and linearity than in GV. After six weeks VSL values continued to be significantly higher in GC than in GL but it was similar in GV and GH. Total sperm abnormalities were within the prescribed limit of semen preservation up to first week after vaccination in all the groups. The results of the present study indicated that Thuja was able to prevent deterioration in sperm kinetic parameters subsequent to FMD vaccination in crossbred bulls.
