| Abstract | ||
| The study was conducted on 50 cows of Holstein- Friesian breed, presented at AL-Faiha farm/ Babylon Governorate, during the period from sep. 2001 to Aug. 2002. The age of Animals ranged from 2-7 years and the number of parturition ranged 1-5 times. The objective of the study was designed to show the effect of prostaglandin F2α and Oxytocine in different doses on uterine involution and postpartum ovarian activity. The Animals were divided into five equal groups.The treatment were give i.m. after 4hr from calving. The first group were treaded with physiological saline 5 ml. The second group were treated with PGF2α 22.5 mg. The third group were treated with oxytocine 50 I.U. The fourth group were treated with oxytocin 100 I.U. The fifth group were treated with PGF2α 15 mg. The Animals were examined per vagina and rectum to measure the cervical opening, observe the lochia, measure the diameter of uterine horns and recorded ovarian activity. The result showed that there was a significant difference (P<0.01) in the mean diameter of cervix between the second (which had the higher involution) and the other groups. It is also observed there was a significant difference in mean diameter of uterine horns (P<0.01) between different groups during 3rd, 4th and fifth weeks postpartum. It was noted that the cervical opening were closed in all groups at the fourth weeks. The second group showed a higher rate of involution in the opening of the cervix. The ovaries were palpated at the fourth weeks postpartum. The ovaries in different treated groups showed activity except in control animals which showed obstetrical problems. The second group showed a higher ovarian activity as compared with the other groups. The lochia were observed untill the 3rd weeks postpartum. The colour were changed from bloody brownish, yellow and clear glassy. The discharge (lochia) were stopped in the 2nd and fifth groups at the 4th weeks postpartum. It was concluded from this study the hormonal treatment with prostaglandin 25mg and/ or oxytocine 100 I.U. could accelerate the uterine involution postpartum in cows. | ||
