Abstract
Objective: This research aimed to determine the behaviors and temperament status and classify animals' temperaments as calm and ill-tempered. Beef cows were subjected to the temperament test, using the chute test and exit velocity test techniques.
Materials and Methods: The reaches twenty-eight Kamphaeng Saen beef cows. The experiment's apparatus consists Camera, Laptop computer, Chute test, and Exit velocity test. Twenty-eight beef cows were subjected to the temperament test, using the chute test and exit velocity test technique. The cows were tested four times and classified animals' temperaments as calm and ill-tempered.
Results: The results' temperament test, using the chute test and exit velocity test technique. The results showed that the low and high means chute scores were 1.94±0.23 and 3.46±0.60 as respectively, and the minimum and maximum exit velocity of where 0.24±0.04 m/s and 0.46±0.17 m/s respectively. The average chute score and exit velocity were used to divide the temperament groups: calm cattle (n=13) and ill-tempered cattle (n=15). A positive correlation was found between chute score and exit velocity (r=0.87, P<0.01)
Conclusion: This study suggested that using chute test and exit velocity techniques for temperament evaluation improves the efficiency of tests and measurement of cattle temperament in both calm and ill-tempered cattle. The chute test and exit velocity test are used as temperament tests to categorize cattle on farms as calm or ill-tempered. Future research on the impacts of temperament as indicated via behavioral variability studies, temperament level, and the development of techniques for measuring temperament in production systems will be helpful in enhancing the productivity of the cattle industry.
