Abstract EN

The study was carried out in the rabbit house at the faculty of Agriculture- Damascus University on 32 weaned rabbits (35 days old) up to age of 90 days.

the study aimed to determine the effect of adding xylanase enzyme to diets on some production indicators of local fattening rabbits.

rabbits were distributed into 4 groups (8 rabbits/group) according to the percentage of the enzymatic additive added, group1(control) without enzymatic additive, whereas 0.2, 0.4, and 0.8 g of enzymatic additive was added to 1 kg of the diet in groups 2,3 and 4, respectively.

rabbits were fed on 4 diets of which materials were identical in their proportions but different in the amount of the enzymatic addition.

results showed positive improvement in the experimental groups for : (mortality, body weight, and fcr) but this improvement wasn’t significant.
