Comparison of the conception rate after fixed time natural mating and artificial insemination in estrous synchronized Murrah buffaloes: A short communication

The present study was conducted to evaluate the conception rate after fixed time natural mating and artificial insemination after Synchronization of estrus in murrah buffaloes. Total 16 murrah buffaloes were selected and randomly divided into two groups, one for natural mating and one for artificial insemination. Buffaloes received estrus synchronization protocol that is, 2mg Oestradiol benzoate intra muscular + 1.38gm Progesterone intra-vaginal on day 0, 12.5mg Dinoprost + 400 IU PMSG intra muscular + removal of the progesterone insert on day 9, 0.0105mg Buserelin acetate intra muscular on day 11 and followed by fixed time natural mating and artificial insemination on day 12 and 13 according to the group. The status of pregnancy was examined by rectal palpation on day 90 post insemination (natural and artificial). All the animals were expressed heat signs and the conception rate was 8/8 (100%) and 5/8 (62.5%) in natural mating and artificial insemination group, respectively. In conclusion, fixed time natural mating may be helpful for the farmers having a small herd of buffaloes.
