蛋鸡低饲养标准饲粮配方的研究

为适应本地区当前生产需要,用低饲养标准饲粮配方,对莱杭鸡的生长与产蛋性能进行了比较试验。结果表明,在整个试验期内,补加鱼粉(1—5%)的试Ⅰ组,和含2种饼类(2—14%)的试Ⅱ组,在体重、料重比(试Ⅰ组—5.87,试Ⅱ组—6.07,对照6.66),产蛋量,料蛋比(试Ⅰ组—3.83,试Ⅱ组—3.88,对照—4.28)和盈利(元/只:试Ⅰ组—1.03,试Ⅱ组—1.23,对照—0.75)等方面较好:但因试Ⅰ组中鱼粉价高而盈利较低;加菜籽饼(2%)和豌豆粉(3—6.7%)的第Ⅲ组与选自生产配方中的对照组,在生产性能与效益方面较低,但仍可盈利,属于低标准、低效益配方,适于在饲养条件差和经营水平低的养鸡场、户采用。

Studies on Diet Formulae for Laying Hens——Ⅰ.on Lower Feeding Standard of Diet Formulae

Comparative experiments were made in lower nutritive level diet formulae for laying hens.The results indicated that the diet containing fish meal in experiment I and the diet containing two oilmeal were better than that of the control in body weight,ratio of feeds to boby weight,egg production,ratio of egg weiht to feeds and economic benefit etc,during the whole period The benefit of exper(?)ment I was lower because of the high price of the fish meal.In experimnt Ⅲ,both the diet containing rapeseed meal and pea meal and diet for comparative group were lower in body weight and egg production but they were better in the economic benefit through the experiment periods.
