Assessment of temperament in and its relationship to stress

Abstract

The delayed domestication of may be associated with their poor temperament and to date there is no published information on the temperament of the farmed Understanding of the temperament and selection program for its evaluation in a breeding herd is important not only for farming but also to other types of animal production. We investigated the temperament of ( = 17) raised in the tropics and determined its relationship with stress. A distance of 13.2 m was fixed for the measurement of flight times. hinds with rapid speed are considered temperamental. Each hind was earmarked for a crush test score between 1 and 5; 1 represents calm and 5 represents highly agitated . Stress was determined by measuring plasma cortisol using a cortisol RIA kit and live weight gain was determined by weighing the animals weekly. The hinds were aged using their date of birth records. We found a strong negative correlation between flight time, crush score, and plasma cortisol concentration ( < 0.05). Animals with very poor temperament have elevated plasma cortisol level and lower weight gain ( < 0.05). It was concluded that flight time, crush score, and plasma cortisol concentration could be used for selecting hinds based on temperament for the breeding herd. This method is quick and easy to implement on a farm; therefore, it remains the test choice for selecting animals based on temperament for the breeding herd.

Semen collection in Rusa timorensis under general anaesthesia by using ketamine-xylazine: Clinical study

“…In deer, there might be different tolerance of individuals towards stress and handling. This trait was displayed by a recent study in R. timorensis which look into the different stress effect between different individuals which suggest different tolerance level towards handling and stress (43). Despite the fluctuation in data, this study suggests intravenous as the best rote of anaesthesia due to the better rate of onset and recovery time in R. timorensis.…”

Semen characteristics, extension, and cryopreservation of Rusa deer (Rusa timorensis)

“…Despite the availability and advancement in technology, AI in deer is still underutilized due to the lack of comprehension in species-specific reproductive traits [ 12 ]. There has been an increase of interest in the female component of R. timorensis reproduction recently [ 13 - 18 ]. Concurrently, a study in stag has also been conducted with the hope to continue on the effort to move the reproduction of R. timorensis towards assisted reproductive technology [ 19 ].…”

Effects of temperament during handling and social rank on the blood biochemical parameters of common eland (Taurotragus oryx)

“…The stress during handling was measured as the behavioural response during handling by a trained researcher (temperament score, a proxy for handling stress; Mahre et al 2015 ; Musa et al 2021 ; Parham et al 2021 ). The final score is the sum recorded at each step of the handling, being 0 for the less stressed animals and 17 for the most stressed ones.…”

“…Social interactions were monitored by a trained researcher in order to obtain a social rank, which was later used as a proxy for social stress (Mahre et al 2015 ; Musa et al 2021 ; Parham et al 2021 ). Ad libitum sampling (Altmann 1974 ) was used to continuously observe agonistic interactions for five hours (0800–1300) each month.…”
