Résumépartiel
The Genetic Evaluation of Sirohi Goat for Selective Value was carried out on 2302 kids belonging to 691 Sirohi does spread over a period of 16 years from 2001 to 2016 at ICAR-Central Sheep & Wool Research Institute Avikanagar, Rajasthan. The longevity, productive flock life (PFL), total female kids reached to age at first kidding (selective value), age at first service (AFS) and weight at first kidding (WFS) were significantly affected by the year of birth, however total kids born (TKB), total female kids born (TFKB), age at first kidding (AFK) and Kidding interval (KI) had nonsignificant effect of year. Only age at first service (AFS) was significantly affected by the kidding season and all other traits had non-significant effect of kidding season. Age at first service (AFS) and age at first kidding (AFK) were significantly affected by weight at first service (WFS) group. The effect of parity was found highly significant on longevity, productive flock life (PFL), total kids born (TKB), total female kids born (TFKB) and selective value. The average value of longevity was 5.84±0.17 years, productive flock life (PFL) was 3.72±0.12 years, total kid born (TKB) was 3.49±0.13, total female kid born (TFKB) was 1.8±0.09, total female kid reached to age at first kidding (selective value) was1.01±0.07, age at first service (AFS) was 1.72±0.02 years, weight at first service (WFS) was 28.18±0.22 kg and age at first kidding (AFK) was 2.28±0.03 years and kidding interval (KI) was 1.25±0.02 years.
