| Sixty male growing NZW rabbits aged eight weeks old, weighed in average 837.0±50.0g were randomly ranked in four equal groups to feed on four experimental diets for 10 weeks. All groups were fed a uniform rabbits pelleted diet, where R1 diet was without supplement ( control ), R2 supplemented with 0.1% Bacillus subtilis , R3 with 0.1% live Saccharomyces cerevisiae and R4 with 0.05% Bacillus s. + 0.05% Sacchromyces c. mixture. The results indicated that the voluntary feed intake did not influenced by bacteria or yeast supplementations, meanwhile body weight gain and feed efficiency were obviously improved ( P < 0.05 ) with diets supplemented with yeast, bacteria or their mixture than control.
