Abstract
- Background: High milk production and excellent fertility is a dream of livestock owners. The major reproductive disorders which lead to decrease the productivity and reproductive ability of farm animals is postpartum anestrous. Recently, kisspeptin was reported as game changer in the animal reproduction. Kisspeptin increases the number of follicles at wave emergence, oestrus response rate and duration of oestrus. Thus, indicating its potentiality for induction of oestrus in anestrous animals. Methods: The present study was conducted to compare the efficacy of Ovsynch and kisspeptin protocol and need of fortification for treatment of postpartum anestrous. Fifty postpartum anestrous cows were selected. The animals were divided into four treatment groups (10 cows in each) and treated with Ovsynch (Group I), Ovsynch fortified with mineral mixture (MM) and bypass fat (BPF) (Group II), kisspeptin (Group III) and kisspeptin fortified with MM +BPF (Group IV). The remaining 10 cows served as control (Group V). The oestrus response was recorded on the basis of behavioral signs, physical signs and clinico-gynaecological changes. The blood was collected following treatment for hormonal estimation. The pregnancy was confirmed on day 45 post AI using ultrasound. Result: The oestrus response was pronounced in Ovsynch as compared to kisspeptin groups. Further, fortification has enhanced the response. The serum oestrogen concentration increased following treatment and was significantly high on day of onset of oestrus with highest concentration in group II. The results indicate Ovsynch distinguishly succeeded in addressing postpartum anestrus with fortification enhances fertility response. However, kisspeptin also emerged as a potent candidate for the resumption of cyclicity. [ABSTRACT FROM AUTHOR]
