A research work was undertaken to induce estrus synchronization in Kilakarsal ewes, using chitosan nanoconjugated GnRH and to assess its efficacy and economic feasibility under semi intensive farming conditions by comparing the same with various drug protocols. Ewes in the control were not given any treatment. The group I ewes were treated with CIDR alone. The group II ewes were treated with CIDR and GnRH. The group III ewes were treated with CIDR and PGF2α. The group IV ewes were treated with CIDR, PGF2α and GnRH. The group V ewes were treated with CIDR and Nanoconjugated GnRH. The group VI ewes were treated with CIDR, PGF2α and Nanoconjugated GnRH. The serum total protein level during the off season on the day of CIDR insertion, CIDR removal, day of estrum, day of mating and on the 70th day of pregnancy in control and different treatment groups ranged from 7.23±0.17 to 7.45±0.11, 6.71±0.10 to 7.06±0.11, 8.00±0.22 to 8.88±0.14, 7.29±0.19 to 7.55±0.11 and 6.53±0.26 to 6.88±0.22 g/dL, respectively. The values observed in groups II and III were significantly higher (P<0.05) when compared with that of the other groups on the day of CIDR removal. On the day of estrum the serum protein values were found to be significantly (P<0.05) lowest in control group when compared with that of the other groups on the same day sampling. It was concluded that the novel protocol of combining CIDR with or without PGF2α and nanoconjugated GnRH was very safe and effective to induce intense estrus synchronization, achieve better % of reproductive performance and may be adopted in the field to increase sheep production.
