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.

马普拉羊品种改良的农民参与式方法

该研究的目的是为马尔普拉绵羊的社区育种计划 (CBBP) 提出一个模型。该研究在 31 个村庄进行了 9 年（2012-2018 年），覆盖了 77 个羊群。平均鸡群规模为 54.39 ± 0.65。研究表明，马尔普拉羊是长日照种羊，8 月至 1 月产羔率为 72.1%。这一时期产羔集中度较高，是为了避免夏季严酷和饲料短缺的压力。由于选择，公羊羔的处置模式很严格。只有 3.1% 的雄性羔羊达到成年期。女性的替代率为34.11%。8,263 只羔羊的活重 (kg) 分别为 3.34 ± 0.01、14.61 ± 0.04、20.48 ± 0.07 和 30.01 ± 0.16，分别为出生、3、6 和 12 月龄。非遗传因素，如性别，出生的季节和年份以及鸡群对生长有显着影响。出生体重、3 个月、6 个月和 12 个月体重的遗传力分别为 0.20 ± 0.03、0.20 ± 0.008、0.23 ± 0.004 和 0.17 ± 0.009。鉴于系统的育种计划，这表明遗传改良的范围已经到位。绵羊育种者采用的当前模式高度依赖政府资助的中央绵羊和羊毛研究所 (CSWRI) 来提供种公羊、数据收集和医疗保健。提出了 CBBP 的替代自我可持续模型，其中育种者组织带头建立公羊饲养中心 (RRC)、公羊选择、数据收集和市场联系的专家团队。CSWRI 将继续使用基于云的“Avimegh”平台协助选择决策和实时数据输入。在 RRC 断奶和饲养时早期选择 5% 的雄性羔羊，直到 12 个月大时的最终选择，将提供 CBBP 下公羊的公正选择。剩余的公羊将由 RRC 出售以获取利润。已建议采取若干关键措施，例如小额信贷、利益相关者之间的协调、市场联系以及数据收集和选择的技术投入，以使 CBBP 能够自我维持。
