Farmer's participatory approach for breed improvement in Malpura sheep

The objective of the study was to propose a model for a community-based breeding programme (CBBP) in Malpura sheep. The study was carried out for nine years (2012-2018) in 31 villages covering 77 flocks. The average flock size was 54.39 ± 0.65. The study revealed that the Malpura sheep is a long-day breeder with 72.1% of lambing during August to January. The higher concentration of lambing in this period is to avoid the stress of harsh summer and scarcity of feed. The disposal pattern of male lambs was stringent due to selection. Only 3.1% of male lambs reach to adult stage. For females, the replacement rate was 34.11%. The live weights (kg) from 8,263 lambs were 3.34 ± 0.01, 14.61 ± 0.04, 20.48 ± 0.07 and 30.01 ± 0.16, for birth, three-, six- and 12-month age, respectively. Non-genetic factors such as sex, season and year of birth and flock significantly influenced growth. The heritability was 0.20 ± 0.03, 0.20 ± 0.008, 0.23 ± 0.004 and 0.17 ± 0.009 for birth, three-, six- and 12-month weight, respectively. This indicated scope for genetic improvement, given a systematic breeding programme, is in place. The present model followed by sheep breeders is highly dependent upon the Government aided Central Sheep and Wool Research Institute (CSWRI) for supply of breeding rams, data collection and health care. Alternate self-sustainable model of CBBP is proposed wherein a breeder's organization leads the way to establish a ram-rearing centre (RRC), teams of experts for ram selection, data collection and market linkage. CSWRI will continue to assist for selection decisions and real-time data entry using a cloud-based "Avimegh" platform. The early selection of 5% male lambs at weaning and rearing them at RRC until final selection at 12-month will provide unbiased selection of rams under CBBP. The surplus rams will be sold by RRC for profit. Several key measures such as micro-finance, co-ordination between stakeholders, market linkage and technical input for data collection and selection have been suggested to make the CBBP self-sustainable.
