Abstract

A study was conducted to determine the effect of prostaglandin F2L (PGF2 L) on the reaction time and seminal characteristics of buffalo bulls viz: color and consistency of the semen, semen volume, sperm motility, mass activity, sperm concentration and percentage of live and normal spermatozoa.

Semen was collected from three Murrah bulls in three periods : pre-treatment (control), treatment and post-treatment periods. During the treatment period, each bull was administered 2 ml PGF2 L (Synchrocept, Fenprostalene) intramuscularly, 1 hour prior to semen collection. In the post-treatment period, semen was collected 7 days after the last injection of PG. Semen samples were evaluated immediately after collection.

Pre-collection injection of PGF2 L has no significant effect on reaction time, semen volume, percentage motility and sperm concentration of buffalo bulls. There is a rice in the number of sperms during the treatment and post-treatment period but the difference is not significant. Fluctuations in semen color and consistency were observed after prostaglandin injection but treatment and post-treatment periods were characterized by thick and creamy semen production. There is a significant (P<0.05) increase in the mean percentage of normal spermatozoa during the treatment and post-treatment and post-treatment periods. Likewise, administration of PG results into a significant (P<0.05) rise in the average percentage of live sperms but this effect was not manifested in the post-treatment period. Improvement in mass activity was observed during the treatment and post-treatment periods.
