Abstract
The present study was designed to investigate the effects of administration of prostaglandin F2 (PGF2 ) during early postpartum on uterine involution (UI), length of postpartum interval (PI), the number of services per conception (NS); days open (DO) and calving interval (CI) in dairy cows. A total of 20 cross-bred postpartum dairy cows were randomly distributed into 2 groups. Group I (n=15) was intramuscularly injected with 500 ?g of PGF2 between the 1st and the 3rd week postpartum. Group II (n=5) was untreated control. The results showed that the time taken for UI was not affected (p>0.05) by injection of PGF2 . However, PI (84.0 ? 7.2 day) , NS (1.1 ? 0.0), DO (85.7 ? 7.9 day) and CI (359.9 ? 7.3 day) of the treated cows were less (p<0.01) than those of the control. It is concluded that the use of PGF2 during early postpartum improves the reproductive efficiency of dairy cows. Thus a calf per cow per year can be produced.
