The therapeutic efficacy of methylergometrine and PGF2α on uterine involution and postpartum fertility was studied in 18 (6/group) Gir cows. Animals of groups I and II were treated with single i/m injection of PGF2α and Methylergometrine immediately after parturition, respectively, while group-III served as untreated control. The time required for expulsion of fetal membranes was shorter in group-I (2.55 ± 0.60 hours) than in group II (3.03 ± 0.34 hours) and group III (4.10 ± 0.36 hours) but did not differ statistically. Time taken for completion of uterine involution was significantly (p Less than 0.05) shorter in group I (28.67±1.12 days) than that of group II (35.83 ± 1.49 days) and group-III (41.00±1.46 days). The intervals for first estrus postpartum and service period were also significantly (p Less than 0.01) shorter for group I (37.83 ± 1.10 and 89.50 ± 4.34 days) than in group-II (46.17 ± 1.40 and 108.33 ± 4.91 days) and group-III (50.83 ± 1.11 and 118.33 ± 4.40 days, respectively). The number of services per conception was non-significantly lower in group I (1.17 ± 0.17) as compared to group II (1.50 ± 0.34) and controlled group III (1.67±0.33). The conception rate was 100% in group I and 83.33 % each in group II and III. Thus, it can be concluded that use of PGF2α immediately after parturition in Gir cows enhanced the process of placental separation, hastened the uterine involution, decreased the service period, increased the conception rate and thereby reduce the calving interval to the profitable ambiance as compared to Methylergometrine and control groups.
The present study was carried out on 80 ejaculates, 20 each from four healthy Jaffrabadi breeding bulls to see the relationship betweensexual behavior and semen quality parameters. The results depicted that the overall mean values of libido score, mating ability score andsexual libido score between bulls. The overall color of semen ranged from thin white to very thick creamy. The overall values for semen volume(ml), pH, sperm concentration (million/mL), mass activity, individual sperm motility (%) and live spermatozoa (%) were 2.99 ± 0.12, 6.80 ± 0.01, 1439.68 ± 48.46, 3.94 ± 0.03, 89.51 ± 0.21 and 95.00 ± 0.19, respectively. The values for semen volume, sperm concentration,mass activity (%) and live sperm (%) differed significantly (p less than 0.05) between bulls. There were significant positive correlations (p LESS THAN 0.01)of libido with mating ability, sexual behavior score and ejaculate volume of semen (r = 0.37 to 0.87), while a negative correlation wasfound with sperm concentration (-0.30). Mating ability was significantly (p less than 0.01) correlated with sexual behavior score and ejaculatevolume (0.78, 0.67), and sexual behavior was correlated with semen volume (0.84). Sperm concentration was significantly (p less than 0.05 correlated with mass activity (0.29), while individual sperm motility was positively (p less than 0.05) correlated with live sperm percentage (0.25).Correlations of libido, reflected the importance of sexual behavior of Jaffrabadi bulls in predicting their future utility as a proficient breeder under AI program.
The actual cause of prolapse of uterus is not clear, but there is no doubt that it occurs during the third stage of labour within a few hours of the expulsion of the calf and at a time when some of the foetal cotyledons have separated from the maternal carbuncles (Arthur, 2001). Prolapse of the uterus is a common complication of the third stage of labour in the buffaloes (Joseph et al., 2001). In ruminants, uterine prolapse is generally a complete eversion of the gravid uterus, wherein multigravidas (dairy bovines) are more often involved than the heifers, while in the sow and the bitch eversion is generally partial and comprises of one cornua only (Arthur,2001; Jackson, 2004). The condition is predisposed by genetic as well as managemental factors and precipitated by straining, parturition and dystocia (Odegaard, 1977). The incidence of vaginal prolapse was observed to be maximum as prepartum prolapse (56.30%), followed by postpartum vaginal prolapse (12.90 %) and vaginal prolapse in non-pregnant (5.70 %) buffaloes (Pandit et al ., 1982). The present paper deals with a case of postpartum complete uterine prolapse and its successful management in a Jaffarabadi buffalo.
Twelve postpartum Jafarabadi buffaloes of University farm were examined gynaecologically between months of February and May 2016 and were found to be either anestrus with smooth ovaries (n=8) or subestrous (n=4) with functional corpus luteum. All the 12 animals irrespective of ovarian status were injected i/m with Busreline acetate 20 μg (Receptal, 5 ml) on day 0, Cloprostenol 500 μg (2 ml) on day 7 and were inseminated twice after 72 and 84 hrs. Second injection of Receptal 2.5 ml was given at the time of 2nd insemination. Six buffaloes returned to estrous on 21st day following insemination which were reinseminated twice at 12 hours interval on reported estrous and injected with 2.5 ml Receptal. Pregnancy diagnosis was done two month post-insemination and conception rate of 50.00% (6/12) to first insemination and 33.33% (2/06) to second insemination was obtained. The overall conception rate obtained was 66.66% (8/12). Thus from the above facts, it can be said that this schedule of modified GnRH-PG-GnRH appears to work effectively in infertile Jafarabadi buffaloes with good conception rate.
