An investigation was undertaken to study the phenotypic relationship among various udder and teat dimensions in Bunaji cows in Kaduna State. A total of 214 Bunaji cows were sampled from three (3) local government areas namely; Kaduna North, Kubau and Zango Kataf. The morphological parameters measured were, udder length, udder depth, udder width, teat length, teat diameter, distance between fore teats, distance between the hind teats and distance between the fore and the hind teats.
All the parameters with the exception of teat diameter were measured using measuring tape in centimeters. Data collected were subjected to correlation and analysis procedure of SAS (SAS, 2004). The results obtained indicates positive correlations in both the udder and teat dimensions and ranges from 0.53-0.78 and 0.15-0.89 for udder and teat, respectively. It can be concluded that there is low to high and positive correlations in both the udder and teat dimensions among Bunaji cows in Kaduna State and these parameters can be used to predict the amount of milk yield.
