Effect of retained placenta on post-partum reproductive performance of Freisian cows
Abstract: The present work was carried out during the period from March to October to study the effect of retained placenta on the post-partum reproductive performance in Friesian cows.
According to the incidence of retained placenta, twenty cows were divided into two equal groups (n = 10), normal cows (G1) and cows with retained placenta (G2). The interval from parturition to complete uterine involution (PPUP), first ovulation (PPOI), first estrus (PPEI), first service (PPSI) as well as service period (SP), number of services per conception (NS/C) and days open (DO) were determined.
The results showed that normal cows compared to retained placenta cows had significantly (P<0.05) shorter PPUI, PPOI, PPEI, SP and DO. while PPSI was insignificantly shorter in normal cows. However, the number of services per conception and incidence of quiet ovulation throughout the 80 days post-partum was similar in the two experimental groups.
