Depletion and repletion of body xanthophylls' reserves as related to broiler pigmentation.

Abstract THE intensity of pigmentation in broilers is related mainly to the total amount of xanthophylls Consumed. This amount is the product of the xanthophylls’ concentration in the diet, the daily feed intake and the length of the feeding period. The investigations concerning the minimum feeding period required for satisfactory pigmentation have resulted in contradictory data. Fritz et al. (1957) and Mitchell et al. (1961) reported that desirable pigmentation can be obtained by feeding xanthophylls-containing diets (22 mcg./gm.) for the last four weeks of the growing period, after chicks had been depleted of their initial zanthophylls’ reserves. Combs and Nicholson (1963) also agreed that supplementation of xanthophylls during the last four weeks was as effective as feeding them for the entire period. According to Couch et al. (1963), the accumulation of pigmenting compounds in the skin and shanks of broilers can be accomplished even in 2.5 to 3 weeks, and hence…
