Abstract: Common eland (Taurotragus oryx) are considered as undomesticated, and maintain their natural prey instincts, making it necessary to habituate them to routine handling. Within this study, data was collected to determine the influence of routine handling and immunocastration on the temperament of common eland. Twenty-nine common eland were divided into two groups: sub-adults (n=15; ca. 2 years old) and juveniles, and were routinely handled every two weeks, over a four-month period. Within each age group, females, males, and immunocastrated males were present. Immunocastration treatment was administered during the second and fourth handling events (2mL Improvac®/ animal). During handling, animals were individually driven through the raceway and finally restrained in a squeeze chute, where routine biological samples and measurements were collected. Faecal androgen metabolite (fAM) concentrations were measured for each event, for males only. Each animal was focally sampled for specific behaviours during the handling. A temperament score was obtained by observing the general state of the animal from the point of entering the raceway, until its exit from the squeeze chute. Generalized linear mixed models tested the influence of immunocastration, week, group, fAM concentration, and body weight on the temperament score. Immunocastration did not affect the temperament score, the general state in the squeeze chute, the order of entering the handling system, and the chute exit. However, the temperament score and the state in the squeeze chute improved overtime (less nervous). Moreover, animals with low temperament scores (calm animals) entered the system earlier and exited the system calmly over the repeated handling period. The results show that routine handling through a raceway and squeeze chute system leads to habituation and improves the ease of handling in common eland. However, immunocastration did not affects the temperament of the male common eland during handling. Authors: Abubakar S.

Preliminary results on relationship between regime of concentrates feeding and size of hard antlers in farmed red deer (Cervus elaphus). 2012, In: Book of Abstracts, 6th Scientific Conference of Institute of Tropics and Subtropisc- Sustainable use of Natural Resources in Tropics and Subtropisc, 2012, Czech University of Life Science, Prague, Czech Republic, 29th-30th November 2012, p. 19 The antlers in deer as secondary sexual trait express the quality of male by its size and as honest signal serve to females to choose the best reproductive partner, who invested the most in this trait. Dominant males whose keep harem of females must frequently fight with challengers and thus not just size, but also composition and compactness of antler is crucial to reduce breakage of antler. To grow every year big and compact antlers, the male need excessive amount of energy and minerals gained by nutrition. To intensively feed deer by concentrates has similar principles as other ruminants, e.g. cattle where overfeeding or irregular provision of concentrates can cause sub-acute or acute form of ruminal acidosis negatively influencing health and production. Because deer breeders apply usually two regimes of concentrate feeding (ad-libitum or restricted with regular serving once a day) we aimed to evaluate its influence on antler size and composition. We had 10 males with ad-libitum access to specially prepared deer pellets and second 17 males were fed by the same pellets once every second day. In both groups were one year old males and three to four years old males. We collect blood samples from vena jugularis three times, in beginning of June, July and August 2012 to monitor blood acid base balance and haematology to detect ruminal dysfunction. Both groups did not differ in any of acid base balance and haematological parameters. Ad- libitum fed group had bigger neck circumference and heavier both antlers in three to four years old males, but not in one year old ones. We had not found differences in antler length and circumferences. Ad-libitum concentrate feeding of red deer males seems to have influence on compactness of antler, but we have not finished mechanical and chemical analyses yet. We had not found any dysfunction based on the feeding regime. .
