肉用优质型寿光芦花种鸡营养需要试验

以代谢能和粗蛋白质为主要研究内容,设高、中、低三个营养水平,测定种鸡在生长期和产蛋期的主要经济性状。结果表明,在低水平下(0～6周龄、7～14周龄、15～22周龄,代谢能分别为2.75、2.75、2.7兆卡/公斤,粗蛋白质分别为17%、14%和11%),种鸡生长期的成活率和体重指标均达到设计要求;在中、低水平下(代谢能2.7～2.6兆卡/公斤,粗蛋白质15～13%),产蛋期的产蛋量、孵化率及健雏数亦达设计指标。

FEEDING TRIALS ON NUTRIENT REQUIREMENTS OF SUPERIOR TYPE OF "SHOUGUANG LUHUA" BREEDING BROILER

The main economic properties of breeding broiler at growing and laying stages were evaluated with high,middle and low levels of metabolic energy(ME)and crude protein(CP).The results showed that the indices designed in livability and body weight had been abtained with low levels of nutrients(2.75,2.75,2.7 Mcal ME/kg and 17,14,11% CP at 0-6 weeks,7-14 weeks and 15-22 weeks of age,respectively),and the indices designed in egg production,hatchability and rate of healthy chick had also been abtained with middle and low levels of nutrients at laying stage(2,7-2.6 Mcal ME/kg and 15-13% CP).
