چکیده
Vitamin D3 is an essential nutrient which plays important role in calcium metabolism for eggshell formation, and phosphorus bone mineralization, maintaining host immunity. Although there have been a great deal of studies investigating the vitamin quality contents eggs, no attempts made to monitor eggs at farm level. Thus, this survey was conducted measure laid from laying hens fed diets containing different levels D3. Eggs four commercial hen farms were sampled before 1, 2, 3 5 weeks after provision D3-enriched added with level 16,500 IU 29,000 IU. Dietary did not affect color breaking strength, but increase thickness. In addition, elevated as increased. It concluded that addition dietary into could improve eggs. expected prediction equation egg might be produced if more data on are analyzed.
