The marginal and landless farmers in India regard goat as “poor man’s crop” and “mobile bank”. Goat occupies a special place in the rural economy of Tamil Nadu. Tamil Nadu is endowed with three meat type breeds of goats viz., Kanni Adu [12], Kodi Adu [5] and Salem Black [9]. Salem Black goats, the recently recognized native goat breed of Tamil Nadu are distributed in Salem, Dharmapuri, Krishnagiri, Erode and Namakkal districts and are reared for meat, skin and manure [1]. The Salem Black goats have good production potential in terms of early sexual maturity and prolificacy. Salem Black goats were reported to produce 48.6 per cent of multiple births (twins 40 per cent, triplets 8.2 per cent and quadruplets 0.4 per cent) under farmer's field conditions [9]. Birth weight is the first observed trait in the life of animal on which growth, production and reproduction traits are dependant. So, the present study was undertaken to investigate the various non-genetic factors affecting birth weight of the kids born under farm conditions.
