“…This review describes a series of research studies demonstrating the impacts of temperament on reproductive success and overall productivity of beef females. Research by our group was the first to document the importance of cattle temperament to overall production of cow-calf systems [ 30 , 31 ], and similar outcomes have since been reported by others [ 73 , 74 ]. One of the mechanisms causing these effects is the increased stimulation of the neuroendocrine response, mounting a stress reaction that culminates with increased release of cortisol into the bloodstream.…”

Temperament is often defined as the behavioral expression of animals in response to human interaction. Cattle temperament can be evaluated using an association of chute score and exit velocity, with cattle then classified as adequate or excitable temperament. To assess the impacts of temperament on various beef systems, these evaluation criteria were associated with productive and reproductive parameters of Bos taurus and B. indicus-influenced cattle. Consistently across studies, excitable cattle had greater plasma cortisol compared to animals with adequate temperament. Studies also reported that excitable beef females have poorer reproductive performance compared to calmer cohorts, including reduced annual pregnancy rates, decreased calving rate, weaning rate, and kg of calf weaned/cow exposed to breeding. Acclimating B. indicus × B. taurus or B. taurus heifers to human handling improved behavioral expression of temperament and hastened puberty attainment. However, similar benefits were not observed when mature cows were acclimated to human handling. Collectively, temperament of beef females measured via behavioral responses upon human handling impacts their reproductive and productive responses independent of breed type, and should be considered for optimal beef cattle production.

“…Most studies examined the effects of temperament on reproduction in beef cattle [ 109 ]. Nellore cows with excitable temperament had a higher serum CC [ 110 , 111 ]. Moreover, more reactive cows had lower serum luteinizing hormone (LH) concentration [ 109 ], possibly due to the reduction of gonadotropin-releasing hormone (GnRH) pulses [ 67 , 112 , 113 ].…”

“…Similarly, the probability of getting pregnant at the beginning of the reproductive season and pregnancy near its end was higher among beef cows characterized by calm temperament than among the excitable ones [ 34 , 69 , 118 ]. Calm Nellore heifers showed a larger diameter of the dominant follicle on the day of timed artificial insemination (TAI) [ 110 ]. In addition, excitability may change the dynamics of ovarian follicles and increase estrus symptoms, which have no connection with the calving outcomes [ 14 ].…”

Temperament is associated with the well-being, health, production and reproduction of cattle. In order to increase the population of individuals with the desired temperament, its evaluation should be standardized and be made one of the obligatory elements of breeding and veterinary examination. A number of different tests are used for temperament assessment. In this article, the importance of temperament correlation with some metabolic, genetic, immunological, production and reproductive parameters have been shown, pointing at its influence on the economy and cattle handling. The most common methods for assessing the temperament of cattle are presented, including long-time scales of temperament assessment. At the same time, the relationship of the temperament of cattle with production efficiency, immunity and reproductive indicators has been shown, indicating that its correct assessment is an important aspect of the proper development of the herd and the associated economic growth.
