| Abstract | The present experiment was conducted on 60 randomly selected dairy units consisting of 116 graded Murrah, 70 Diara type and 121 nondescript type buffalo cows utilizing the procedures of stratified random sampling with proportional allocation (Snedecor and Cochran, 1967) in and around Patna (Bihar). The aim of this investigation was to study the effect of genetic and nongenetic factors on various morphometric traits of buffaloes under farmer's management system. The morphometric traits included in the study were height at wither (haw, cm), body length (bl, cm) and chest girth (cg, cm) as well as body weight of the adult buffalo cows. The genetic factors were the three different genetic groups of buffaloes viz. graded Murrah, Diara and non-descript types prevalent in Bihar (India), whereas the non-genetic factors included in the study were location of herd, farming system and sequence of lactation. The farming system and the order of lactation had significant (P LT 0.05) influence on HAW, BL and CG whereas location of animals did not influence these traits. The animals managed under mixed farming system had significantly (P LT 0.05) higher estimates of morphometric traits than those maintained in the units involved dairying alone. The animals of first order of lactation had the lowest magnitudes of all the morphometric traits and significantly (P LT 0.05) increased upto third parity indicating that the skeletal maturity of the buffaloes might be attained at the age of 3rd parity. |
