“…Treatment of subestrus animals with PGF 2α , on the day a palpable and functional CL is present favours the onset of estrus [8,23]. The previously reported conception rates at induced estrus in subestrus cattle [20] and buffaloes [25] were comparable to those in the present study.…”

ABSTRACT. A total of 130 animals (82 cattle, 48 buffaloes) with histories of anestrous 60-90 days post-partum and belonging to different agroclimatic zones of Punjab were subjected to rectal palpation and blood samplings at least three times at weekly intervals. The body condition score (BCS) of each animal was also recorded. The animals were divided into two groups; viz., true anestrous (Gp-I) and subestrus (Gp-II) through rectal palpation of ovaries and plasma progesterone (P4) concentrations. Furthermore, the Gp I and II animals were divided into treatment (Gp Ia, 40 cattle and 16 buffaloes; Gp IIa, 12 cattle and 14 buffaloes) and control groups (Gp Ib, 20 cattle and 8 buffaloes; Gp IIb, 10 cattle and 10 buffaloes). True anestrous animals (Gp Ia) were treated with 3 injections of hydroxyprogesterone caproate (750 mg, i.m.) at 72-hr intervals followed by injection of equine chorionic gonadotropin (eCG; 750 I.U., i.m.) 72 hr after the last progesterone injection. The animals were bred at the first estrus after the induced one. The first service conception rate (FSCR), overall conception rate (OCR), services per conception and pregnancy rate of the true anestrous treated cattle (Gp Ia) were 44.4%, 48.0%, 2.08 and 60.0%, respectively. In the true anestrous control cattle (Gp Ib), only five that were observed to be in estrus failed to conceive. In the anestrous treated buffaloes (Gp Ia), the FSCR, OCR, services per conception and pregnancy rate were 50.0%, 62.5%, 1.6 and 62.5%, respectively. No buffalo amongst true anestrous control (Gp Ib) showed estrus. The subestrus animals (Gp IIa) were administered Prostaglandin F 2α (PGF 2α ; 25 mg Dinoprost, i.m.) and bred at induced estrus. Amongst the Gp IIa animals, all cattle (100%) and twelve buffaloes (85.7%) responded to treatment. Of these animals, the FSCR and pregnancy rate at induced estrus in the cattle were 50.0% each, whereas they were 66.6% and 57.1%, respectively, in the buffaloes. The subestrus control animals (Gp IIb) remained infertile. In summary, the plasma P 4 profile can be used to differentiate true anestrous and subestrus animals and thus to determine a hormonal therapy. Furthermore, fertile estrus can be induced with hormonal therapy in anestrous and subestrus bovines. KEY WORDS: anestrous, buffalo, cattle, conception rate, subestrus.J. Vet. Med. Sci. 70(12): 1327-1331, 2008 The early return to cyclicity after calving is a prerequisite for high reproductive efficiency in dairy animals, that is, cattle and buffaloes. To maintain the recommended calving intervals, the animals need to conceive as soon as possible (85-90 days for the cow and 100-150 days for the buffalo) [7]. Increased intervals from calving to conception are due to deferred commencement of ovulation and estrus expression and reduced pregnancy rates, thus increasing the culling rate of the dairy herd.An increased calving-to-conception interval as a result of true anestrous or subestrus in bovines adversely affects the economics of the dairy sector. The incidence of true anestrous in th...

“…It has been reported to differ from 2.8 to 3.7 days (Repasi, et al, 2003;Levy, et al, 2006;Wenzinger & Bleul, 2012). Such difference might be related to the individual responsiveness (Roy, et al, 1972) and age of the corpus luteum in relation to the estrous period (Singh, et al, 1979). From the present study, there is no difference in number of services per conception between both treated groups (Table, 1).…”

“…In addition to high costs of medication and early depreciation of potentially useful cows (Thomas, 1989;Barnouin & Chacoranc, 1992;Merga, 1992).The use of PGF2α in treatment of retained corpus luteum (CL) has been widely advised (Plunkett, et al, 1984;Ahmed, 1993). However, the effect of PGF2α depends mainly on the presence of corpus luteum in the ovaries by its action as a luteolytic factor (Singh, et al, 1979). The present investigation was undertaken to assess the efficacy of single over-dose of PGF2α to induce estrus in post-parturient anestrus dairy cows with persistent corpus luteum.…”

A B S T R A C TThe present study aimed at evaluating the effect of single over-dose of PGF 2α on postpartum anestrus due to retained corpus luteum in dairy cows. A total of 40 dairy cows, 3-8 years old and 1-6 parities used in these study, were assigned into two comparable groups; control group of 20 cows were injected by 500µg from PGF 2α and over-dose group of 20 cows were injected by 750 µg from PGF 2α i.m. The obtained results indicated the presence of a significant increase in the heat response (85 vs. 65%), decrease in the time elapsed from treatment to heat (2.47 vs. 4.53 days) and the serum progesterone level, 24 hrs. and 48 hrs. after treatment, in the over-dose group than that in the control; there was a nonsignificance difference in the number of service per conception and the conception rate between both groups.

“…Later studies with buffaloes (Pathiraja, Abeyratne, Perera & Buvanendran, 1979) emphasized the importance of correct detection of oestrus, AI technique, and adequate nutrition. Buffaloes treated during the breeding season are more fertile than those treated for suboestrus with first-service conception rates of 51-52%, and 25-44% respectively (Rao & Rao, 1979a;Singh, Dugweka, Sharma, Chauhan & Singh, 1979a (Chauhan et ai, 1982) and cows (Dobson, Cooper & Furr, 1975). In field conditions only 55-72% buffaloes and zebu displayed oestrous symptoms after PG treatment (compared to 80-90% in dairy cows); this may be due to the extra difficulties of initial luteal recognition per rectum because progesterone concentrations at the time of PG injection have been as low as 0-6 ng/ml (Chauhan et ai, 1982;Orihuela, Galina, Escobar & Riquelme, 1983).…”
