A study was undertaken on Thalli sheep to evaluate the non-genetic factors affected on animal’s birth weight in Southern Punjab, Pakistan. Non-genetic factors along with genetic factors are important influential factors in determining the performance of animals. Data on 239 lambing records were analyzed using Statistix 8.1 software. The average birth weights calculated were 3.40 ± 3.34 kg. Significant effects of birth weight were observed by environmental factors like birth type, flock, sex of lamb, and year of birth. Non-significant i.e. (P>0.06) values were observed throughout the study for the season of birth. Males were heavier than females according to their birth weights. Similarly, single-born lambs have more bodyweight than of twins.
