Abstract

The influence of different forms of dietary selenium (Se) on vitamin E (alpha-tocopherol) and Se contents of egg yolk and chicken meat was investigated. 2. Eggs were collected from laying hens subjected to 4 different dietary treatments after 24 weeks of age. Treatments compared the effects of inorganic Se supplementation (selenite) to those of organic (Se-enriched yeast, Se-enriched alga Chlorella) supplements. In a second experiment the effect of the above organic dietary Se supplementation on the alpha-tocopherol contents of meat from broiler chickens was evaluated. 3. Dietary Se supplementation increased the alpha-tocopherol content of egg yolks from 297 mg/kg dry matter in treatment without supplementation to 311 mg/kg when selenium was supplemented as selenite, and to 370-375 mg/kg when organic supplements were used. The Se and alpha-tocopherol contents of breast and thigh meat in broilers were significantly increased by organic dietary Se supplementation. 4. The inclusion of organic dietary Se sources in the diets of laying hens and broilers would enhance the nutritional value (vitamin E and Se contents) of products (eggs and meat) for human consumption.

摘要

研究了不同形式的膳食硒（Se）对蛋黄和鸡肉中维生素E（α-生育酚）及硒含量的影响。2. 24周龄后，从接受4种不同日粮处理的蛋鸡中收集鸡蛋。处理组比较了无机硒补充剂（亚硒酸盐）与有机硒补充剂（富硒酵母、富硒藻类小球藻）的效果。在第二个实验中，评估了上述有机膳食硒补充剂对肉鸡肌肉中α-生育酚含量的影响。3. 膳食补充硒使蛋黄中α-生育酚含量从未补充硒时的297毫克/千克干物质增加到补充亚硒酸盐时的311毫克/千克，使用有机补充剂时增加到370 - 375毫克/千克。有机膳食硒补充显著提高了肉鸡胸肉和腿肉中的硒及α-生育酚含量。4. 在蛋鸡和肉鸡日粮中添加有机膳食硒源可提高供人类食用的产品（鸡蛋和肉类）的营养价值（维生素E和硒含量）。
