English Abstract

Thirty-six growing Rabbits male, 5 weeks old, with initial weights of 776.67±9.71 gm were used for the study.

The rabbits were randomly allocated to four treatments groups of 9 rabbits each.

Group one fed basal diet free of feed additives and served as a control group.

Groups 2 and 3 supplemented with 200 and 400 mg Thyme leaves / kg diet, respectively.

Group 4 received control diet, but drinking water supplemented with 200 mg ascorbic acid /L.Results showed that at 13 weeks of age the supplementation of 200 mg ascorbic acid, 200 and 400 mg Thyme leaves /kg diet brought a significant (P ≤ 0.05) improvements in final body weight(g) by the value of 2119.4, 2250, 2360.6 and 2232.8 total of weight gain(g) by 1341.7,1502.8,1584.4 and 1457.2 feed conversion ratio by 3.83,3.22,2.96 and 3.43 and significantly (P ≤ 0.01) decreased daily feed intake(g) by 91.42,86.78,86.77 and 90.2, respectively.

Most of the carcass traits were insignificantly affected by different treatments, however, kidney fat and lungs percentage were significantly (P ≤ 0.05) decreased and increased, respectively, in the group received 400 mg Thyme leaves in comparison with control.

Digestibility coefficients of DM was insignificantly (P ≤ 0.05) decreased in the groups received Thyme leaves, however, digestibility coefficients of OM was insignificantly (P ≤ 0.05) but decreased in the group had 400 mg Thyme leaves in compared with control and ascorbic acid fed groups.

Diets containing Thyme leaves caused significant (P ≤ 0.05) increment in DCP % value compared with control and ascorbic acid fed groups.

In conclusion the results showed that addition of Thyme leaves or ascorbic acid in rabbit diets had improved the productive performance, carcass, digestibility of growing rabbits and 400 mg/kg Thyme leaves was more effective tan 200 mg/kg Thyme leaves or ascorbic acid.
