| Popis: | [EN] The study aimed to evaluate the effect of Arak (Salvadora persica) as feed additive on performance of pre and post-sexual maturity of rabbit males. A control diet was formulated with an estimated proportion of 18% crude protein and 14% crude fi bre. Another three diets were formulated supplementing control diet with 0.1 0.2 or 0.3% Arak. The Arak used in this study contained (as % DM basis): 27.9 ash, 12.4 crude protein, 1.7 ether extract and 8.0 crude fi bre. Ninety-six weaned Black Baladi (BB) male rabbits aged 30 d weighing 570±8.30 g (mean±standard error) were used (24 per diet). Daily weight gain and daily feed intake were recorded from weaning up to 70 d of age (slaughtering commercial age). At this time four rabbits from each group were slaughtered and genitalia were immediately taken and dissected. Blood samples were collected at 120 and 150 d of age from fi ve bucks from each group. At the age of maturity several reproductive traits were also recorded. Final body weight at 70 d of growing BB rabbit males increased linearly and quadratically (P |
