The study was carried out to explore the phenotypic relationships and dependencies among temperament traits that significantly affect the functions of Bunaji cows. Fifty-one (51) multiparous Bunaji cows that were non-pregnant, lactating in their third stage of lactation were used for the study. The cows were tagged and certified clinically fit by animal health personnel. The techniques implored to assess the animals' temperament traits were chute, chute exit score, chute exit speed and facial hair whorls positioning. All the data in the experiment were analyzed using SAS (2000) version 9.0. Computations using means procedure were done to determine the means and standard errors for each trait; and coefficients of variation (CV). Pearson's correlation coefficients were computed to determine the degrees of relationship among and between variables for all animals within each temperament group. Significant differences in means were compared using the Duncan Multiple Range Test (DMRT). The major findings showed that chute temperament score (CT), chute exit score (CES) and chute exit speed (FS) were highly (P < 0.01) correlated traits. Temperament had significant (P<0.05) effect on exit speed and body measurements. The result suggested that reactive had faster exit speed. It is thus concluded that cows that walked (CES1) and trot (CES 2) while exiting the chute were calmed. Therefore, handlers need to be conscious of temperaments of cattle to ensure safety. The study could also be replicated for other breeds of cattle. [ABSTRACT FROM AUTHOR] |
