Hormonal induction of oestrus in anoestrous buffaloes

Abstract

The efficacy of a 9 day progestagen treatment in combination with eCG was evaluated for induction of
ovulatory oestrous, restoration of ovarian cyclicity and fertility in rural anoestrous buffaloes maintained either
on paddy straw plus dried jowar (group I) or with urea molasses mineral mixture block (UMMB) supplement
· (group IT) during their non-breeding season (summer). Honnonal therapy was quite effective in the induction of
oestrus but the conception rate at the induced.oestrus was vecy poor (8.3% vs 13 .5%). The UMMB supplement
improved the energy balance of animals (serum glucose value; 24.8 vs 50.3 mg%) and consequently the
incidence of ovulatory oestrus (16. 7 vs 53.3%) and the establishment of ovarian cyclicity (25.0 vs 60.0%).
Further studies are needed to delineate the role of nutrition and its interaction with season in assessing the
response to honnonal therapy for treatment of true anoestrus in rural buffaloes
