Study on the effect of probiotics on preventing diarrhea and enteritis of rex rabbit;

Effects of vitamin A and vitamin E on the reproductivity performance of Rex rabbit;

The effects of supplemental microbial phytase in diets on the growth performance and mineral excretion of rex-rabbits;

40 healthy rex-rabbits with three-month old were randomly assigned into 4 groups(10 rex-rabbits in each group)to determine the effects of phytase and VD3,and their combination on production performance and nutrient avalability of growing rex rabbits.

Two experiments were conducted with German-American crossbred growing rex-rabbits, to investigate the effects of supplementing lower phosphorus diet with either phytase,vitamin D3 (VD3),or their combination, on the performance and nutritive avlability by Rex-rabbits.
