| dc.description.abstract | ABSTRACT : The aim of the present study was to test the efficacy of the Norgestomet and Ovsynch alone and in combination for the treatment of postpartum anoestrus buffaloes on conception rate. The present study was conducted on forty eight postpartum (3 to 8 months) anoestrus buffaloes suffering from postpartum ovarian inactivity confirmed on the basis of rectal palpation and serum progesterone concentrations. Buffaloes were randomly assigned in to three treatment groups and a control group of twelve animals each. Buffaloes in treatment Group A (Ovsynch) were administered 20μg of GnRH (Receptal) on the day of initiation of treatment, Seven days later 25mg of PGF2α (Lutalyse) administered and again 10μg of GnRH (Receptal) on day 9. Buffaloes in treatment Group B (Norgestomet) were treated by inserting a Crestar ear implant containing 1.3gm of norgestomet and 2ml of Crestar injection containing 3mg of norgestomet and 5mg of estradiol valerate on the day of initiation of treatment. On day 7, PGF2α @ 25mg was injected intra muscularly and Crestar implant was removed on day 9. Buffaloes in treatment Group C (Ovsynch plus Norgestomet) were treated with Ovsynch protocol plus Crestar ear implant for a period of seven days starting from first GnRH (Day 0) to PGF2α injection (Day7) of Ovsynch. The buffalo cows which were bred at natural physiological estrus were treated as control (Group D). The buffaloes which responded exhibited estrus within three days and were bred at observed induced estrus and at subsequent estrus. Higher number of postpartum anoestrus buffaloes, treated with Norgestomet in Group B and C exhibited intense to intermediate estrus, while in Ovsynch treated Group B the estrus signs were intermediate to weak. The estrus response following hormonal treatment was 66.66 (8/12), 100.00 (12/12), and 100.00 (12/12) per cent in A (Ovsynch), B (Norgestomet) and C (Ovsynch plus Norgestomet) groups, respectively. An ovulatory response of 75 (6/8), 66.66 (8/12), 75 (9/12) per cent were observed in Ovsynch, Norgestomet, Ovsynch plus Norgestomet groups, respectively. The conception rates at induced estrus were 16.67 (2/12), 33.33 (4/12), 41.67 (5/12) per cent in Ovsynch, Norgestomet, Ovsynch plus Norgestomet groups, respectively. The overall conception rate among the anestrous animals treated was higher (75.00%) in Ovsynch plus Norgestomet group followed by Norgestomet (58.33%), Ovsynch (25.00%) and 16.67 per cent in control group. The progesterone profile could be used to assess the anestrus, estrus, luteolysis and CL formation which is an indicative of ovulation and thus used to determine the effectiveness of hormonal therapy. | en_US |
