Effect of Dietary Lysine Supplementation on Performance Production and Egg Quality of Laying Hens
Main Article Content
Abstract
The objective of this study to determine the effect of lysine levels in diet on performance production and egg quality of laying hens. One hundred femalesof Isa brown and 50 weeks-old laying hens were study. Laying hens were randomly allocated to 5 groups with ten replicates of 2 Laying hens. The experimental diets contained 16% protein, 2,900 kcal/kg and 5 difference lysine levels (0.80, 0.90, 1.00, 1.10 and 1.20% in diets). Laying hens were feed and water freely available at all times. The results show laying hens fed the diet with different lysine levelsdid not effect on production performance, feed intake, feed conversion ratio, protein efficiency ratio, egg production, egg weight, and egg masswith the nonsignificant difference (P>0.05). While the egg quality, albumen weight, yolk weight, shell weight, haugh unit, yolk color, eggshell strength and shell thickness were not different (P>0.05). In conclusion, laying hens 50 to 54 weeks of age received lysinehigher than 0.80% showed the results to improve the production performance and egg quality of laying hens (P>0.05).
