The aim was to estimate non-genetic factors affecting morphometric traits of Marwari goats under field condition. The morphological information pertaining to Marwari goats (n=36,566) during different stages of life, viz., birth, 3 months, 6 months, 9 months, 12 months, 18 months, 24 months and adult (>2 years) was collected from farmer’s flock maintained under AICRP-Goat Project under field condition and born during 1990 to 2015. The effect of different non-genetic factors, viz. year of birth, season, sex and cluster on the different body measurement were estimated through least square analysis method of general linear model. The effect of cluster and year of birth was found to be highly significant (P≤ 0.01) on all the morphometric traits for all age groups. Influence of season of birth was highly significant (P≤ 0.01) on body height at all age group. The effect of season of birth was observed as highly significant (P≤ 0.01) on length and heart girth at all stages except birth. The sex of kid significantly (P≤ 0.01) affected the height at birth, 3, 6, 9, 18, 24, on length at birth, 3, 6, 9, 24 and adult ages, on heart girth at 3, 6, 9, 12 months. The different non-genetic factors significantly affected the morphometric features in Marwari goats.
