Abstract
This experiment was carried out at Seds Experimental Station and Animal Nutrition Section, Animal Production Research Institute, Agriculture Research center to study the effect of some medicinal plants (fennel, rosemary, thyme) and citric acid as antioxidant on lamb performance.
The results could be summarized as follows:
1- The best additive effect was thyme followed by rosemary on reducing the peroxide number by (31%, 30%) respectively and lowest was citric acid (21%). The best additive in reduced the thiobarbutric acid was thyme (52%), fennel (52%) and the lowest value was recorded with citric acid (34%). Values of thiobarbutric acid and peroxide number were increased with time advanced of cotton seed meal and olive cake.
2- Digestibility coefficients of OM were significantly higher with R3 rosemary and
R4 thyme (81.6, 81.6) than control and citric acid being 79.3% and 79.8
%respectively. All additives improved OM, CF digestibilities compared with the control rations. CP digestibility was higher in R3 (rosemary) 72.9% than Rl (control) and R4 (thyme) 69.5 and 69.5% respectively and lower than R5 and R2 68.3 and
68.7% respectively.
3- Additives increased TON and DCP % than the control. The highest TON value was recorded with R4 {thyme) 85.5%, while the lowest value was found by control group
84.4%. For DCP the highest value recorded with R3 (rosemary) while the lowest value recorded with R2 (fennel).
4- Compared to the control group, lambs fed R4 (thyme) followed by R3 (rosemary)
exhibited higher final live body weight 47 and 45 kg respectively and the best body
