日粮中添加苜蓿粉对蛋鸡血液指标的影响研究

选取30周龄海兰白蛋鸡240只,随机分为10组,每组24只,进行饲养试验。对照组饲喂玉米—豆粕型日粮,试验组日粮中添加3%、6%、9%的苜蓿草粉,6%、8%、10%的苜蓿叶粉。在试验期间测定不同比例的的苜蓿粉对蛋鸡生血液生化指标的影响。添加苜蓿叶粉还可以降低血液中的胆固醇和甘油三脂的含量,对肝、肾功能没有明显的影响(P>0.05)。

Effect of Adding Alfalfa Leaf Meal to Hen Diet on Serum Parameters in the Late Part of Laying Stage

240 Hyline White Laying hens,aged 30—weeks,were allocated to 10 groups at random and each group included 24 laying hens respectively. A feeding experiment was conducted to determine the serum parameters of layers fed 0、3%、6%、9% alfalfa meal(AM)and 6%、8%、10% alfalfa leaf meal(ALM).The result indicated that Layers fed alfalfa leaf meal have lower cholesterol of serum than those fed based diet. Layers fed leaf meal have apparent variance compared to treatment. Layers fed grass meal on 3% level significantly decreased CHO and TR of serum while there are not apparent affection on the function of liver and kidney.
