Effect of supplementation of different levels of Hibiscus and Rosemary to diet in productive characteristics of Broiler ROSS308

Abstract

Abstract An experiment was conducted on chicken meat’s chicks (cv. ROSS308) in private poultry farm in Anbar governorate. A total number of 240 (Ross 308) chicks were randomly distributed on five treatments with four replicates, each replicate contained 12 birds. T1 was left without any addition as a control. T2 and T3 were the addition of 0.75 and 1.5% from Hibiscus powder to the diet respectively while 0.75 and 1.5% from Rosemary powder were assigned to T4 and T5 respectively. Body weight, weight increase, diet consumption, the efficiency of feed conversion and then calculating of efficiency productive coefficient at the end of the experiment period were studied. The results of the experiment showed that there were no significant differences between treatments in the period from 1 to 42 days in mean of body weight, weight increase, and significant increase in diet consumption in Rosemary treatment 1.5% (T5). The addition of these powders of medicinal plants has significantly improved the efficiency of feed conversion especially at the use of Rosemary 1.5% (T5) as well as the treatment of 0.75% from Rosemary powder has improved from Dressing percentage of carcass. The treatment of using Hibiscus powder T3 (1.5%) formed better productive coefficient followed by Rosemary powder T5 (1.5%) and then control with significant difference from the rest of treatments
