Effect of PGF2 treatment on conception rate and blood biochemical profile of postpartum suboestrous surti buffaloes

Abstract

Postpartum suboestrous surti buffaloes of an organized farm confirmed by twice per-rectal palpation 11 days apart from 45 days post-partum were treated with 2 ml (500 g) of inj. cloprostenol sodium I/M route in first group (n=6) and 2 ml (500 g) of inj. cloprostenol sodium I/M route along with 5 ml inj. Vit. AD 3 E preparation and 15 ml inj. Toldimphos sodium preparation I/M route in second group (n=6) on 55 days postpartum after confirmation of ovarian cyclicity. Six animals of same status were kept as control to see the oestrus induction response and conception rate including weekly evaluation of blood biochemical profile just before (0 day) treatment and 24 hr, 48 hr and 72 hr after treatment. The service period and oestrus induction interval in days was found significantly lower in PGF 2  treated (T 1 and T 3) groups as compared to T 2 and control (T 4) group clearly showed the luteolytic effect of PGF 2  on ovaries and earlier resumption of ovarian activities as compared to treatment (T 2) and control groups. The mean serum glucose, total protein, cholesterol, calcium and phosphorus levels of suboestrous surti buffaloes did not differ significantly within all the treatment and control groups and also between all the treatment and control groups at 0 hr, 24 hr, 48 hr and 72 hr interval including overall mean values in all the groups.

Serum metabolic and minerals profile in norgestomet primed postpartum anestrous surti buffaloes

“…The increasing trends toward follicular phase may be the reason for significantly higher overall values on the day of estrus as compared to other days in all three groups. These findings on overall mean serum total cholesterol concentrations in anestrous buffaloes are in close agreement with those (122.80±4.85 to 156.63±14.59 mg/dl) reported by earlier workers [ 11 , 13 - 16 ] in anestrous cows and buffaloes, and 153.74±5.46 mg/dl reported by Chaudhari [ 9 ] in the delayed pubertal Kankrej heifers following norgestomet ear implant plus PMSG treatment. In addition to this, higher overall mean plasma cholesterol levels in Surti buffaloes during the breeding season were recorded by Prajapati [ 17 ].…”

“…Khasatiya et al . [ 11 ] reported significantly higher overall pooled mean of blood plasma total protein in postpartum anestrous treatment group than that of control group (7.70±0.13 vs. 7.01±0.21 g/dl), in Surti buffaloes. Serum protein levels change with different stages of reproduction, depending upon the feed intake of the animal.…”

“…The present overall mean serum copper level was in agreement with the reports of Shah [ 24 ] and Khasatiya et al . [ 11 ] in Surti buffaloes. Chaudhari [ 9 ] reported mean serum copper concentrations to vary significantly at different time intervals in the norgestomet treatment group as well as in norgestomet plus PMSG treatment group.…”

“…The observations made in the present study before, during and after treatment as well as on the day of estrus were found to be non-significant between and within the group including overall means were in agreement with the findings of Khasatiya et al . [ 11 ] and Soni [ 8 ] in postpartum Surti buffaloes. Cobalt is required for the synthesis of vitamin B12 and its deficiency has been associated with anestrous, abortions, non-functional ovaries [ 28 ], birth of weak calves and general infertility [ 29 ], delayed onset of puberty [ 5 , 30 ].…”

“…The mean serum iron and manganese levels of anestrous Surti buffaloes also did not differ significantly (p > 0.05) between sampling days or between groups at any of the days, and the findings were in close agreement with Soni [ 8 ], Chaudhari [ 9 ], and Khasatiya et al . [ 11 ]. Although, Shah [ 24 ] found significantly higher overall pooled me n iron level in anestrous treated than anestrous control Surti buffaloes (1.18±0.03 vs. 1.05±0.04 µg/ml).…”
