| dc.description.abstract | The present study was conducted in clinically healthy, normal cyclic cows (N=20) with no history of reproductive abnormality at the Department of Veterinary Gynaecology and Obstetrics and Livestock Farm Complex, CSKHPKV, Palampur. All the cows were monitored for behavioural signs like mounting, standing to be mounted, bellowing, vulvar oedema, and cervicovaginal discharge at the time of estrus. The physical parameters of cervicovaginal discharge such as consistency, quantity, color, pH, spinnbarkeit, and fern pattern were recorded. Thereafter, trans-rectal B-mode and color Doppler sonography of the ovarian and uterine characteristics along with the middle uterine artery of cows was done. The objectives of the study were to evaluate the relationship between different ultrasonic characteristics of ovaries and uterus with conception rate and analysis of the blood flow through a middle uterine artery at estrus for prediction of ovulation time. Spinnbarkeit, the physical property of cervicovaginal discharge, was significantly higher (p0.05) for pH was recorded. The preovulatory follicle at estrus had a significantly higher (p0.05) was recorded for uterine characteristics i.e., intraluminal uterine fluid diameter and endometrial thickness. Similarly, the vascularity of mid cyclic corpus luteum was significantly higher (p0.05) in relation to pregnancy. The pulsatility index and mean blood flow volume were significantly higher (p<0.05) in the MUA ipsilateral to preovulatory follicle at estrus as compared to contralateral MUA. Also, the pulsatility and resistivity indices along with velocity (TAMAX) of blood flow to the uterus through MUA ipsilateral to preovulatory follicle at estrus were significantly higher (p<0.01-0.05) in cows ovulated within 24 hours of A.I. as compared to cows ovulated after 24 hours. | en_US |
