Crossbred Jersey Cows, Involution, Reproductive tractAbstract
The study designed to assess the normal reproductive tract involution in postpartum crossbred Jersey cows. Pluriparous crossbred Jersey cows (n = 10) which had recently calved were subjected to ultrasonographic assessment for postpartum involution once in two days till complete involution. The results showed that the involution time required for the vagina and cervix was 23 and 29 days respectively. The Mean ± SE of vaginal and cervical involution (cm) varied from 2.15±0.07 to 1.12±0.07 and 3.76±0.10 to 1.74±0.09 respectively. The uterine involution (cm) of gravid and non-gravid horn diverge from 4.27±0.12 and 3.47±0.14 to 1.89±0.13 and 1.67±0.14 respectively from day 4 to 23. The present findings document the reference value and period of reproductive tract postpartum involution in crossbred Jersey cows.
