Productive Performance of poultry Supplementation of Medicinal Plants

The experiments of the current study were carried out in the poultry scientific research house in Gardarasha/ Animal resource Dept.- Collage of Agricultural Engineering Sciences, Salahaddin University- Erbil Kurdistan region, Iraq. This study included two experiment, each of seven treatments with three replicates. Two stocking densities were applied in both experiments. The first experiment was for the broiler, 705 days- old chicks commercial Ross 308 were raised in 2m2 in each pen for 35 days, the stocking density as followings; T0 (negative control, standard density) 75 chicks, 25 chicks (12-13 birds/ m2) per replicate. From T1 till T6 the chicks were reared under high stocking density105 chicks for each treatment and each replicate was obtained 35 birds (17-18 birds/ m2). The second experiment was conducted for layer, from 10th August till 1st December, 240 (31) weeks- old commercial ISA-Brown layers were reared for 16 weeks in different conditions of the experiment and the stocking density was as the following; T0 (negative control, normal density) 8 layers/ 1.20 m2 (7 layers/ m2). From T1 till T6 the layers were under stocking density 12 layers / 1.30 m2 (9 layers/ m2).
