Effect of norgestomet on induction of oestrus in cattle: An overview

Abstract

Late attainment of puberty, silent oestrus and anoestrus are among the major constraints of reproduction in the breeding programme of farm animals that have direct impact on farmers' economy. Application of exogenous hormones that are available in the market constitutes powerful potential to address such reproductive problems of animals confronted by the farmers while rearing them for gainful purpose. The use of norgestomet along with compounds like oestradiol valerate and PMSG effectively enhanced puberty, induction and synchronization of oestrus entailing fertility in several breeds of cattle. Reproductive parameters associated with evaluation of efficacy appertaining to norgestomet applications and factors influencing their functions were discussed in this brief overview.
