摘要
大蒜是一种植物鳞茎 ,作为肉牛饲料添加剂尚未见报道。本文研究的目的是 :研究大蒜对肉牛增重的影响。试验选用西门塔尔杂交后代公牛 3 8头其中 3 5头牛随机分为七组 ,大蒜组 A( 50 g/ d.头 )、D( 1 0 0 g/ d.头 )、F( 1 50 g/ d.头 ) ;大蒜素组 C( 0 .2 g/ d.头 )、E( 0 .4g/ d.头 )、G( 0 .6g/ d.头 ) ;对照组。试验采用完全拉丁方设计。试验结果表明 :1 .大蒜在添加 74.6g/ d.头左右 ,对肉牛增重有明显的促进作用 ,Y=-0 .0 0 2 2 x2 +0 .3 2 8x+2 8.3 2 ,R2 =0 .972 8( Y为增重 ,X大蒜用量 )。 2 .当大蒜素添加量为 0 .3 5g/ d.头时肉牛体增重最高 ,y=-92 .5x2 +65.4x+2 7.3 3 R2 =0 .91 96( Y为增重 ,X大蒜素用量 )。 3 .
Garlics are often used as ingredient in human diet,but have not been reported as an additive for beef cattle feed.In this research,38 bulls of Simmental were used to study the influence of garlic on liveweight gain of beef cattle?35 of the bulls were randomly divided into 7 groups: garlic A (garlic 50g/day/ head)?garlic D (garlic 100g/day/head)?garlic F (garlic 150g/day/head); allitridi C (allitridi 0.2g/day/head)?allitridi E (allitridi 0.4g/day/head)?allitridi G (allitridi 0.6g/day/head); control (neither...
