Abstract
Laying hens production has undergone a paradigm turnover in its primarily concept and operation from extensive backyard activity into a major commercial production. Antibiotics have been used as antimicrobial growth promoters in animal to improve food safety. However, in order to avoid the possible risk of developing resistant pathogens, as well as to meet the public pressure of antibiotic free animal products, the use of antibiotic in poultry diet was totally banned in European Community [1]. Various alternatives of phyto additives have been studied in order to maximize the growth performance of laying hens in the diets without antibiotics.

Summary
Effects of Turmeric Powder (Curcuma Longa) in Laying Hens Nutrition: Table Eggs Production, Quality and Lipid Profile. In order to achieve appropriate colour of the yolks, hens diets should be supplemented with yellow or red pigments, natural or synthetic. The use of synthetic pigments in organic production is completely banned while in some countries, like Sweden, government regulation does not allow the use of synthetic pigments even in non-organic commercial production. Due to their harmfulness and increase of consumers’ awareness, there is a growing interest in replacing synthetic pigments with natural [2]. Researchs reported that 2g/kg of turmeric powder decreased the feed conversion ratio (FCR), increased yolk color, decreased serum triglycerides, total and LDL-cholesterol [5]
