Use of different levels of sunflower meal (SFM) in commercial leghorn type layer diet

Utilization of sunflower meal (SFM) with hulls in leghorn type layer diet was studied in a completely randomized design (CRD) experiment with 4 treatments, 8 replicates and 4 hens in each replicate. After determining chemical composition of SFM, four diets with including equal ME (2900 kca/kg) and cp (14.5%) containing 0, 5, 10 and 15 percent SFM were formulated. During the experiment, daily feed consumption, hen - day egg production, egg weight, feed conversion ratio (kg feed/kg egg) and mortality were measured weekly. In the begining and the end of the experiment body weight of the hens were measured individually. The results indicated that utilization of 10 percent hulled SFM had no adverse effects on daily feed consumption, hen - day egg production, however, increasing SFM consumption up to 15 percent decreased daily feed consumption, hen - day egg production and egg weight decreased 5.70, 7.06 and 5.49 percent respectively while, feed conversion ratio increased significantly (p<0.05). Accorrding to the results it can be concluded that 10 percent SFM with hulls can be used in egg type lager diet.
