Digestive rate of Dongtian F 1 red Dear in weaning period and growth period

In this paper, 4N-HCLAIA method was adopted to conduct digestive tests in young female and male Dongtian F 1 red deer ( Cervus elaphus ) of rearing seperately in growth period and mixed raising in weaning period in Harbin Specialty Research Institute. Results indicated that digestive rate of crude protein and crude fiber were 95.35% and 73.68% respectively when rational protein content was 26.8% in growth period, Digestive rate was not significantly different between female and male(P>0.05); During weaning period, when rational crude protein content is 22.06%, digestive rate of crude protein and crude fiber were 93.05% and 63.96%, respectively. The tests suggest that higher rational protein can be effective in accelerating growth of young Dongtian F 1 red deer during growth period and weaning period(before 10 months old).
