Prostate gland The prostate gland composed of central isthmus and two lateral lobes; each was rather triangular with a concave dorsal 40 Mohamed M. Appl Anim Behav Sci This supports the finding that free ranging Przewalski's horses increase their activity and feeding budgets at night compared to daytime levels in the summer months, due to high temperatures and disturbance by flying insects .
This is perhaps due to the close age of animals or small size sample under study, regarding that these donkeys already post-pubertal and perhaps some of them approached the age of maturity. In the meantime, verifying the effect of age ap- proaching young or surpassing maturity old on the acces- sory sex gland biometry in jacks. Gender differences in emotional reactivity have been identified in horses, with mares being more easily panicked and aggressive than geldings  ; our findings suggest similar gender differences in donkeys. This study has also helped refine the working donkey ethogram by investigating changes in behaviours over time, enabling inclusion of the behaviours which are most robust and useable in the field at any time of day. Teddy and Sam go out to buy ice cream, leaving Kareena and Kyle alone together. For those that did let the observer start the test, avoidance scores did not differ significantly with time of day Wilcoxon Many stallions with ejaculatory problems were found to suffer from large cysts at the Col. Holm S A simple sequentially rejective multiple test procedure. Ultrasonography is an easily ap- plicable noninvasive method, provides information related to the clinical fertility evaluation of the jack. No comparable published behavioural research could be found, therefore the results of this study can only be considered in the context of this study group and environment. Behavioural observations in the current study were limited to daylight hours; pilot studies using video-recording of behaviour at night were unsuccessful due to an erratic power supply. All other postural behaviours and event behaviours were consistent across the test days.

The gross anatomy of accessory genital glands was studied in-situ and separately. The Bulbourethral glands BUG appeared at the dorso-lateral aspect of the pelvic urethra. This indicated the significance of sexual stimulation on the gland activity and consequently its dimensions. Female donkeys appeared to be less focused on the external environment than the males, expressed by their level head carriage. Also, the measured dimensions were close to that reported in horses These are components of a normal social and sexual behaviour repertoire  ,  and are indicative of the male donkeys' strong motivation to investigate surroundings and interact with con-specifics. It seems that Teddy is not alone with intimacy issues. Appl Anim Behav Sci 60 — The prostatic lobes appeared as a hypoechoic elongated structure enclosing an echogenic lumen Fig. This provides strong evidence for the robustness of these behaviours over time and their inclusion in a working donkey ethogram. This shape and features come in accordance with the gross anatomical description made by Mai The actors are in their skin with these roles, spot on. Therefore, the present investigation was performed to provide a basic knowledge for the purpose of establishing clinical reference values of the different accessory sex glands based on ultrasound topographic and anatomical features in donkeys.
