The aim of this study was to determine the influences of polymorphism of transferrin on some the physical traits in Black Bengal goat. The material of this study comprised of 199 adult Black Bengal does. The least square analysis of data revealed that the overall estimate of body length, heart girth, height at wither and body weight of adult Black Bengal does were found to be 16.875 ± 0.131 inches, 25.504 ± 0.248 inches, 16.452 ± 0.152 inches and 14.306 ± 0.159 kg, respectively. The does having TfCC phenovariant performed better than other phenovariant for all physical traits except heart girth. The maximum estimate for TfCC phenovariant in this study were 17.443 ± 0.407 inch for body length, 16.782 ± 0.449 inch for height at wither and 15.202 ± 0.508 kg for body weight. The highest estimate of 26.699 ± 0.867 inch for heart girth was observed in TfBC phenovariant does. White colour variety does performed paramount compared to other three coat colour of Black Bengal goat for all physical traits. The average value observed for different physical traits in white colour variety as 17.309 ± 0.264 inch for body length, 26.351 ± 0.425 inch for heart girth, 16.959 ± 0.344 inches for height at wither and 14.736 ± 2.994 kg for body weight. White colour does having TfAC phenovariant performed most excellent for body length (18.711 ± 0.841 inches) and heart girth (30.139 ± 0.574 inches) while white colour with TfAA phenovariant showed maximum value for height at wither (18.5285 ± 1.215 inches). However, black colour with TfCC phenovariant showed maximum value for body weight (16.457 ± 0.754 kg). In this study, the relationship between the phenovariant observed in locus of transferrin, coat colour and interaction of both with all the physical traits were statistically non-significant.
