| dc.description.abstract | ABSTRACT: The present investigation” Effect of Ovsynch,CIDR and Ear Implant on Induction of Estrus and Fertility in Post Partum Anestrus Buffaloes “ was taken up in dairy experimental station, Rajendranagar, Hyderabad and dairy farms in and around Rangareddy distict to study the efficacy of Ovsynch, CIDR, and Crestar therapeutic protocols in inducing estrus and enhancing conception rate. The major incidence of reproductive disorders was observed to be due to functional (64.75%) and the remaining being infectious causes (32.47%) and anatomical causes (2.76%) in the buffaloes. Among 8598 buffaloes analyzed for their reproductive disorders, 159 (1.84%), 79 (0.92%), 1438 (16.72%), 763 (8.87%), 1605 (18.67%), 398 (4.62%), 286 (3.32%),146 (1.69%), 194 (2.25%), 172 (2.00%), 566 (6.58%),482 (5.60%),637 (7.40%), 1482 (17.23%), 38 (0.44%), 153 (1.78%), 0 (0%) and 0 (0%) were observed to be hypoplasia of ovaries, genital infantilism, smooth ovaries, postservice anestrus, postpartum anestrus, silent ovulation, anovulatory heat, luteal persistency, luteal cysts, follicular cysts, repeat breeder, vaginitis, cervicitis, endometritis, metritis, pyometra, salphingitis and bursal adhesions, respectively. The incidence of postpartum anestrum among buffaloes was observed to be 18.67 per cent. The experimental buffaloes were randomly divided in to 4 groups each consisting of 20 each. The mean values of serum progesterone levels recorded in postpartum anestrus buffaloes before treatment in Ovsynch group, CIDR group, Crestar group and Control group were found to be 0.69±0.06, 0.67±0.13, 0.74±0.07 and 0.81±0.17 ng/ml respectively.The mean values of serum progesterone levels (ng/ml) on the day of termination of treatment in Ovsynch group, CIDR group, Crestar group and Control group were 4.54±0.10, 18.99±0.174, 2.16±0.026 and 16.76±0.22 nanograms respectively. The mean values of serum progesterone levels (ng/ml) after the treatment with Ovsynch on Day 3, Day 5 and Day 7 were found to be 3.56±0.012, 1.97±0.01 and 0.177±0.004 respectively. The mean values of serum progesterone levels(ng/ml) after the treatment with CIDR on Day 3, Day 5 and Day 7 were found to be 1.30±0.021, 0.15±0.003 and 1.21±0.02 respectively. The mean values of serum progesterone levels (ng/ml) after the treatment with Crestar on Day 3, Day 5 and Day 7 were found to be 0.155±0.003, 1.49±0.03 and 2.31±0.036 respectively. Among 80 postpartum anoestrus buffaloes treated with various protocols, the estrus response was found to be 80, 60, 85 and 35 percent, respectively in Ovsynch, CIDR, Crestar and control groups. The days taken for the onset of estrus in Crestar (2.41±0.37days) was found to be lower than Ovsynch (7.25±0.58 days), CIDR (5.41±0.37 days) and control (31.16±3.07 days) groups. The intensity of estrus was observed to be better in Ovsynch and Crestar groups than in CIDR and control groups. The intense estrus symptoms were observed to be 50, 41.1, 16.6 and 16.6 per cent in Ovsynch, CIDR, Crstar and control groups, respectively. The duration of estrus was found to be significantly longer in Crestar (41.88±6.26 hrs) treated buffaloes. Similarly the interval between treatment and onset of estrus was observed to be significantly earlier in Crestar (2.41±0.37 days) group than in Ovsynch (7.25±0.58), CIDR (5.41±0.37 days) and control 31.16±3.07days), groups, respectively. The first service conception rate even though high in CIDR (66.66 per cent) group, the combination of first service conception rate and overall conception rate is better in Ovsynch (54.55 and 68.75 per cent, respectively) group and Crestar (60 and 58.82 percent, respectively) than CIDR ( 66.66 and 50, respectively) and control (0 and 33.33 per cent, respectively) groups. The mean number of services per conception in anoestrus postpartum buffaloes treated with Ovsynch, CIDR, Crestar and control groups were recorded as 1.45±0.16, 1.33±0.21, 1.4±0.16 and 2.5±0.5, respectively and found to be somewhat lower service per conception in CIDR treated buffaloes than in any other groups. | en_US |
