STUDIES ON EFFECT OF INTRAUTERINE THERAPY WITH OZONATED OILS AS A PROPHYLACTIC APPROACH FOR POSTPARTUM UTERINE INFECTIONS IN CROSSBRED DAIRY COWS
(KARNATAKA VETERINARY, ANIMAL AND FISHERIES SCIENCES UNIVERSITY, BIDAR, 2021-01) CHIRANTH, J. P.; NARASIMHA MURTHY
Thirty six normally calved crossbred dairy cows were randomly divided into 3 groups with 12 each to evaluate the prophylactic efficacy of intrauterine ozonated oil on uterine involution pattern, uterine bacterial load reduction, postpartum uterine infections and their subsequent reproductive performance. Group I served as control and Group II and III received one time and two time intrauterine ozonated oil (100 mL) on day 5-7 and 14, respectively. Uterine involution pattern and uterine aerobic bacterial studies were done on day 7, 14, 21, 28 and 35 pp. All the animals were screened for postpartum uterine infections using vaginoscopy and endometrial cytology and their reproductive performance were recorded. Observations recorded from uterine involution assessment and total uterine bacterial count revealed that reduction rate of uterine size and bacterial load was similar in both control and preventive ozone infused groups. Following intrauterine administration of ozonated oils, none of the study cows were found positive for puerperal metritis on day 10-14 pp. However, incidence of clinical endometritis examined on day 21(Group I vs II vs III; 33.33 vs 25 vs 25%) and sub clinical endometritis on day 28 pp (Group I vs II vs III; 25 vs 25 vs 16.6%) and on day of subsequent estrus (Group I vs II vs III; 16.6 vs 16.6 vs 8.3%) were noticed. In conclusion, the present study revealed that the prophylactic effect of intrauterine ozonated oil on uterine involution, reproductive performances and in preventing postpartum uterine infections is non-significant among different study groups.

AUGMENTATION OF FERTILITY BY HERBAL AND HORMONAL PROTOCOLS IN POSTPARTUM ANESTRUS COWS
(KARNATAKA VETERINARY, ANIMAL AND FISHERIES SCIENCES UNIVERSITY, BIDAR, 2021-03) MOHD MUJAHEED PASHA; R. G. BIJURKAR
The present study evaluated the fertility response and serum profile changes in progesterone and biochemical constituents in 18 postpartum anestrus (>60 days) cows, treated under field conditions with Estrona feeding at 125gm/day/animal for four days (group II; n=6) or CIDR-Synch protocol (group III; n=6) and an untreated Control (group I; n=6). The animals were observed for estrus signs and inseminated. The estrus induction rates in group I, II and III were 16.66, 66.66 and 100.00 per cent with conception rates of 0.00, 50.00 and 66.66 per cent, respectively. The mean serum progesterone concentration (ng/mL) measured before (0th day) and after (30th day) treatment increased nonsignificantly (P<0.05) in group II and significantly (P<0.05) in group III, when compared between the groups, group I had significantly low progesterone on 30th day of treatment compared to other two groups. The overall mean calcium and phosphorus concentration (mg/dL) varied significantly (P<0.05) within group II and mean glucose concentration varied significantly (P<0.05) in group III. However, no-significant difference was observed in cholesterol concentration observed in groups I, II and III, before (0th day) and after (30th day) treatment. To conclude, above results indicates that the feeding of Estrona powder and progesterone-based CIDR-Synch protocol improved estrus induction and conception rates in postpartum anestrus cows. Key words: CIDR-Synch, Estrus induction, Estrona powder and Postpartum anestrus cows

EFFECT OF SUPPLEMENTATION OF SAFFLOWER OIL IN OVSYNCH ON FERTILITY OF POSTPARTUM BIDRI GOATS
(KARNATAKA VETERINARY, ANIMAL AND FOISHERIE'S SCIENCES UNIVERSITY, BIDAR, 2020-01) RAVIKIRAN, S.; Dr. R G. BIJURKAR
The study was conducted to find out the effect of safflower oil supplementation combined with ovsynch estrus synchronization protocol in postpartum Bidri goats. Twenty four full term pregnant goats were selected and divided into 3 groups (n=8). From day of kidding, all the 3 groups were fed with concentrate feed (250 gm/day/doe) for 30 days. Group one (T0) was kept control and maintained on concentrate feed without additional supplementation. Treatment groups – Group 2 (T1) and Group 3 (T2) received safflower oil supplementation at the rate of 30 gm and 50 gm/day/doe respectively, for 30 days. Ovsynch (G-P-G) estrous synchronization protocol was carried in all 3 groups from day 16 postpartum. All animals received a I/M inj of GnRH @ 4 mcg on day 16 post kidding and I/M inj of PGF2α @ 250 mg on day 23; Upon observing of estrus signs, does were allowed for natural mating. All the animals received second I/M inj of GnRH @ 4 mcg on day 25 (48 hours after PGF2α injection). Estrus induction rates for all the 3 groups were 100 %. Conception rates for T0, T1 and T2 were 50%, 75% and 100% respectively. Mean ± SE values of onset of estrus for Group T0, T1 and T2 were found to be 62.25±1.66, 49.625±1.48 and 41.25 ± 1.71 hr respectively. Mean ± SE values of duration of estrus for Group T0, T1 and T2 were found to be 38.25±1.21, 46.125±0.89 and 42.75±3.50 hr respectively. Serum samples were estimated for progesterone, glucose and cholesterol levels. Based on conception rate, it was noticed that safflower oil supplementation augmented conception rates in both Group 2 (T1) and Group 3 (T2). It was concluded that Group 3, which received 50 gram safflower oil + Ovsynch had better efficiency in increasing conception rate of postpartum Bidri does.
