Abstract
The current study investigated the effect of different levels of dietary black seed on the immune status of different strains of laying hens. A total of 600 pullets were used, 300 from Hy-Line Variety W-98 white and 300 from Hy-Line Variety brown. The white and brown pullets were divided into five groups, 60 pullets each, which was divided into three replicate (n=3), each replicate includes 20 pullets. The first group received a regular diet with no black seed (T1, control group). The second group received a diet containing 1.5% black seed from 28 wk of age until 70 weeks of age (T2). The third group received a diet containing 3.0% black seed from 28 wk of age until 70 weeks of age (T3). The fourth group received a diet containing 1.5% black seed from 16 weeks of age until 70 weeks of age (T4). The fifth group received a diet containing 3.0% black seed from 16 weeks of age until 70 weeks of age (T5). The immune parameters used were antibody titers, cell- mediated immune response and white blood cell counts (WBCs). Results showed that feeding layer chickens on 1.5 or 3.0% black seed increased the total WBCs in both laying strains, and the difference was significant for the white hens (P<0.02). Black seed generally enhanced cell-mediated immune response and antibody titer, however, this effect was not significant. In conclusion, black seed dietary supplementation could be used to enhance the immune status of laying chickens.
