Estrus Induction Response Vis-a-Vis Serum Progesterone and estradiol 17-β Profile in Postpartum Subestrus Surti Buffaloes Primed with Heatsynch Alone and Heatsynch plus PRID Protocol

response of lactating karakul ewes to two levels of exogenous estradiol 17.B along with progesterone and pregnant mare serum for induction of fertile estrus at early postpartum

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

AIM The study was undertaken to find out the serum metabolic and minerals profile in postpartum anestrous surti buffaloes treated with norgestomet ear implants alone and in combination with pregnant mare serum gonadotropin (PMSG). MATERIALS AND METHODS The study was conducted on 18 postpartum anestrous Surti buffaloes divided into three groups of six animals each at random to conduct the expe...

Estrus induction and fertility rates in response to exogenous hormonal administration in postpartum anestrous and subestrus bovines and buffaloes.

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 subes...

Evaluation of the Heatsynch protocol in Murrah buffaloes (Bubalus bubalis) during hot summer season

The objective of this study was to evaluate the effect of the Heatynch protocol on plasma estrogen concentration in Murrah buffaloes and to evaluate if the Heatsynch protocol induces estrus in Murrah buffaloes. All treated animals responded to the treatment by displaying obvious signs of estrus. The mean plasma estrogen concentration among the individual buffalo was 191.9 ± 68.3 pg / ml after E...

Comparison between two progesterone sources and two oestradiol formulations in a Heatsynch protocol for postpartum cycling dairy cows in pasture

To compare an injectable progesterone (MAD-4) with an intravaginal device (IPD), and natural O17 with synthetic oestradiol (OB) in a synchronisation protocol, 51 cows were divided into four groups. Each group was treated with one of the two sources of progesterone and one of the two oestradiol formulations. Oestrus behaviour, follicle diameter, and pregnancy rates were evaluated. Oestrus behavi...
