Begait cows, Body measurements, canonical discriminant analysis., farming systems, principal component analysis


Breed characterization in the livestock is important to obtain the breed standard of livestock for selection program. This research was aimed to characterize the Begait cows (Bos indicus) reared in two different farming systems (on-farm and ranch) in Ethiopia using 15 body measurements. A total of 344 adult Begait cows kept in on-farm (n = 237) and ranch (n = 107) systems were involved in this study. The principal component analysis (PCA) was performed to describe the morphostucture of the animal study. Thus, the canonical discriminant analysis (CDA) was performed to classify the animals from two different farming systems. The PCA and CDA analyses were performed using SPSS 16.0 computer program. The results revealed three principal components (PC's) in animals reared in on-farm system, and four PC's were found in animals reared in the ranch system. Thus, the PCA in this study able to explain the morphostructure of cows about 52.01 % (on-farm) and 63.26 % (ranch). Morever, seven body measurements were detected as the discriminant variables for Begait cows with canonical correlation (rc ) of 0.57 (moderate). In addition, the discriminant analysis of body measurements able to classify Begait cows about 77.6 % (on-farm) and 82.2 % (ranch system) into their original farming system. It can be concluded that the morphostructure of Begait cows appears to be affected by the differences in management systems, indicating their usefulness for breeding programs in the future.
