花尾榛鸡食物营养的研究

STUDIES ON FOOD NUTRIENTS IN HAZEL GROUSE

采用生物化学分析技术，对花尾榛鸡 Ｔｅｔｒａｓｔｅｓ ｂｏｎａｓｉａ ａｍｕｒｅｎｓｉｓ的年周期所吃食物营养组成进行研究。结果表明，食物中营养素粗蛋白质（Ｃ．Ｐ）和粗脂肪（Ｃ．Ｆａｔ）含量，均以５月最高（２０．４６％、１４．６５％）；粗纤维（Ｃ．Ｆｉｂ）含量９月最高（４１．４４％）；粗灰分（Ｃ．Ａ）和无氮浸出物（Ｎ．Ｆ．Ｅ）含量，各月之间差别均不明显。矿物质磷（Ｐ）、钙（Ｃａ）、钾（Ｋ）、镁（Ｍｇ）、铁（Ｆｅ）的含量，均以５月最高。维生素（ｖＡ、ｖＥ、Ｂ１、Ｂ２、Ｂ６）的含量，也以５月最高。总糖和碳水化合物含量，两者变化规律基本相同，即１—２、８—１２月的相近，３—７月的相近。总氨基酸含量，以５月最高。

The present paper deals with the studies on the contents of periodic nutrient compo- nents for Hazel grouse (Tetrastes bonasia amurensis) yearly by using food-chemistry analysis technique. The results showed: It showed the highest contents in May in crude protein and crude fat in food nutrient (20. 46%. 14. 65 % ). In september the crude fiber took the first place of contents of food (41.44%). None of difference was found in the contents of crude ash and nitrogen-free extracts in monthly examination. On May. the mineral contents of P. Ca. K. Mg. Fe .showed the highest (0. 48% . 1.53% 。40. 25ppm. 0. 88ppm. 2.05ppm respectively). In May the contents of vitamin A. E. B1. B2. .B6 (69. 5mg/kg, 98. 2mg/kg, 2. 4mg/kg, 7. 2mg/kg and 3.7mg/kg) took the first place also. The contents of the general saccharide and carbohydrate changed: regularly. The contents of amino acid in the food. showed the highest: (10. 726% ) in May during breeding period off the bird,
