Records of 1016 Marwari lambs born from 1987 to 1992 at Central Sheep and Wool Research Institute. Arid Zone: Campus, Bikaner, were used to study the effect of selection line, year of birth, sea of lamb and generation on growth. Significant effect of year of birth was found for absolute growth rate and relative grown rate, while sex of lamb, selection line and generation had significant effect during some periods of absolute growth rate and relative growth rate. Estimates of heritability were low to medium.
