| Different levels of thyme vulgarize were added to broiler ration in experiment was conducted in private farm in heat in the period from 9/1/2009 to 26/2/2009 . 150 chicks were used in this experiment from Hubbard strain. The chicks were divided into five treatment randomly. Each treatment was divided in three replicates ten chicks were put in each replicate. Starter and grower rations with different levels of thyme vulgarize were fed to chickens. The treatment were 0, 0.2, 0.4, 0.6 and 0.8 of thyme vulgarize added to the ration named T1,T2, T3, T4 and T5. The traits were studied were body weight, weight gain, feed consumption and feed conversion each week. Production Index and growth rate were then studied at the of the experiment. The results showed significant effect of treatment on some of the traits were studied especially T5 in the performance of the broiler, and it significant superior in accumulation properties studied which reach (2244g, 2202g, 3704.99g and 1.69) for body weight, gain weight, feed intake ratio treatment was significant superior in production index and growth faster, from this we conclude there was potentional for added the thymo to poultry ration in order to improve. The production performance for broiler. |
