Abstract

The effects of supplementation of the maternal diet of quail with three natural sources of carotenoids (alfalfa nutrient concentrate (PX agrotrade mark), tomato powder and marigold extract) on the accumulation of retinol and retinyl esters in egg yolk and in the liver of the new hatchling and maternal were investigated. The present study showed that the vitamin A in quail egg yolk was present in 4 different forms, namely retinol (R 52-62%), retinyl linoleate (RL 9-11%), retinyl stearate (RS 4%), retinyl oleate (RO 11-15%) and retinyl palmitate (RP 13-22%). The retinyl ester profile of the liver of newly hatched quail (R 2-4%, RL 8-12%, RS 19-21%, RO 12-15%, RP 50-55%) differs from that of egg yolk but was similar to that of the liver of adult quail (R 1%, RL 5-6%, RS 21-28%, RO 9-12%, RP 54-63%). It has been shown that RO and RP concentrations in egg yolk and the liver of day old quail chick significantly increased as a result of carotenoid supplementation of the maternal diet.

摘要

研究了在鹌鹑的母源日粮中添加三种天然类胡萝卜素来源（苜蓿营养浓缩物（PX 商标）、番茄粉和万寿菊提取物）对新孵化雏鸟和母体蛋黄及肝脏中视黄醇和视黄酯积累的影响。本研究表明，鹌鹑蛋黄中的维生素 A 以 4 种不同形式存在，即视黄醇（R 52 - 62%）、亚油酸视黄酯（RL 9 - 11%）、硬脂酸视黄酯（RS 4%）、油酸视黄酯（RO 11 - 15%）和棕榈酸视黄酯（RP 13 - 22%）。新孵化鹌鹑肝脏中的视黄酯谱（R 2 - 4%，RL 8 - 12%，RS 19 - 21%，RO 12 - 15%，RP 50 - 55%）与蛋黄不同，但与成年鹌鹑肝脏的视黄酯谱相似（R 1%，RL 5 - 6%，RS 21 - 28%，RO 9 - 12%，RP 54 - 63%）。结果表明，由于母源日粮中添加了类胡萝卜素，雏鹌鹑一日龄时蛋黄和肝脏中的 RO 和 RP 浓度显著增加。
