The activity and use of zinc in poultry diets

Zinc (Zn) is an important nutrient in poultry and its deficiency has been linked with various disorders, in addition to depressed growth and performance. It is now recognised that Zn has a major role in antioxidation, growth and development, production, immunity and stress related issues. Supplementation of Zn can improve growth, augment immunity, enhance antioxidant capacity, increase endocrine secretion and interact with other minerals in the gut. In this review, some of the basic information regarding the importance and activity of Zn within the body and the addition of Zn in poultry diets is discussed.

Alternations in Cholesterol and Fatty Acids Composition in Egg Yolk of Rhode Island Red x Fyoumi Hens Fed with Hemp Seeds (Cannabis sativa L.)

The present study was designed to evaluate the influence of hemp seed (HS) supplementation on egg yolk cholesterol and fatty acid composition in laying hens. Sixty hens (Rhode Island Red x Fyoumi) were evenly distributed into four groups (three replicates per group) at the peak production (34 weeks). HS was included into the ration at the level of 0.0 (HS-0), 15 (HS-15), 20 (HS-20), and 25% (HS-25) and continued the supplementation for consecutively three weeks. At the end of the experiment, three eggs per replicate were randomly collected and analyzed for egg yolk fatty acids and cholesterol profile. The statistical analysis of the result revealed that supplementation of HS-25 significantly decreased egg yolk total cholesterol, myristic (C14:0), palmitic (C16:0), and stearic (C18:0). Similarly, total as well as individual monounsaturated fatty acids decreased significantly while total and individual polyunsaturated fatty acids increased significantly in the HS-25. In addition, total omega-3 and omega-6 increased significantly in the HS-25 group. From the present result, we concluded that addition of HS at the rate of 25% to the diet of laying hens augmented the cholesterol and fatty acids profile in egg yolk.
