Abstract
The experiment was designed to study the effect of dietary Nano-selenium on productive, immunological performance, oxidation resistance and selenium deposition in tissue of laying hens- A total number of 180 laying hens of Silver Montazah strain were used. Layers were divided randomly into six treatments. Five Nano-selenium diet concentrations (200, 160, 120, 80 and 40 mg/ton for treatments (T2, T3, T4, T5 and T6), respectively. The treatment (T1) was used as control with 200 mg/ton diet sodium selenite.
The results were discussed and summarized as follows:
Application of Nano-selenium in layer diets was effective in increasing egg number, egg mass, total serum protein, and albumin. Also, Nano-selenium improved some immunological traits, feed conversion, some egg quality traits and some antioxidant enzymes traits. The optimum level of Nano-selenium was 200 mg/ton diet, which recorded 5.409 feed/g egg mass compared to 9.249 feed / g egg mass in control treatment (200 mg/ton diet) Application of 200 mg/ton diets Nano-selenium were significantly decreased total cholesterol, high density Lipoprotein, triglycerides, heterophils (H%) and H/L ratio. Where, Lymphocyte was significantly (p≤ 0.01) increased. The concentration of selenium in liver, breast meat and whole egg were 30.9%, 40.5% and 102.3% higher in layers fed 200 mg/ton diet Nano- selenium compared to layers fed 200mg/ton sodium selenite. layers fed 200mg/ton diet Nano- selenium had 5.6 % and 5.4 % higher in dressing and edible meat, respectively.
