Abstract

This study was conducted to characterize quantitative and qualitative traits from selected breeds of cattle and their relationship in semi-arid zone of Nigeria. A total of 60 lactating cows comprising of 20 each of Bokoloji, Rahaji and Bunaji breeds of first parity were used. The cows were milked three times in the late rainy season August to September in two weeks interval by the same person across the breed. The milk yield was measured with a graduated cylinder and 20 ml milk sample was used for protein and fat contents analysis. The data obtained were subjected to Analysis of Variance (ANOVA) using Statistical Analysis System (SAS) and significant means were compared using Duncan Multiple Range Test (DMRT). The degree of relationship between all pairs of variables was computed using CORR Procedure of the SAS. The result showed breed had a significant (P < 0.05) effect on milk yield, protein content, fat yield and protein content with Bokoloji having a superiority in milk yield (2.18), protein content (4.93), fat yield (6.64) and protein yield (10.78) while Rahaji and Bunaji were statistically same in milk yield (1.56 and 1.82), protein content (4.25and 4.28) and protein yield (6.56 and 7.84) respectively except fat yield (4.70) which was least in Rahaji. There were both positive and negative significant (p<0.05-0.01) correlation between milk yield and compositions likewise positive and significant (p<0.05-0.01) correlation were observed between milk yield with protein composition, fat yield, protein yield while a negative significant (p<0.05) correlation between milk yield and fat in all the three breeds. It was concluded that Bunaji breed was found to be the best in milk improvement programme in the semi-arid zone in Nigeria as it excelled in milk yield (2.18 kg), protein content (4.92%) and protein yield (0.11 kg).
