The results showed that there were more than 30 kinds of common plants favored by L.timibus. The linear regression equation of weight gain was y=-23.223+30.929 x. The molting sequence in spring successively was head, dorsum, ear,both sides of the chest, abdomen, limbs, tails.展开更多
Abstract The feed formula for Bonasa bonasia at different biological periods are introduced in the paper, in order to provide reference for breeding of B. bonasia.

Vixens were timely injected with appropriate exogenous hormones at proper ratio to increase their ovulation and litter size, thereby improving the fecundity of silver fox. The average litter size in experimental group attained by 5.86 to 6.0 whelps, 1.61 - 1.75 whelps more than that in the control group. The hormone combination in the experimental group was high in performance/price ratio, which had no significant impact on fecundity of vixens in future.展开更多
The characteristics of digestive system,breeding habits,feather growth and molting of Tetrao parvirostris were studied,in order to provide the scientific basis for artificial breeding of T.parvirostris.
