Abstract

A total of 75 HF crossbreds belonging to first and second parity with rural farmers of Tarai
region of India were studied for the association between morphometric traits and production traits
(estimated lactation milk yield and average lactation fat per cent). The morphometric traits included 11 biometric and 7 derived traits, measured at 15 days apart for three months pre and post-partum period. For the first lactation, significant association was observed between BL, EBW, HWBL, BS, TFT with milk yield and with BS for fat per cent. The traits like BL, GIR, EBW, HWBL, HWGR and HWPG and PGIR had their significant association with milk yield and like BL and HWBL with fat per cent in second lactation in rural H.F. crossbred cows. All these correlation coefficients were suggestive of their usefulness in selecting the animals for milk and fat.
