本试验旨在研究饲喂大蒜粉对肉仔鸡生产性能、消化率、消化器官、屠体组织和脂肪含量的影响。试验选用270只1日龄Cobb-500雏鸡。鸟被分成三个试验组，每组90只。每个处理由6个重复组成，每个重复15只鸡。对照组饲喂商品起始日粮和肥育日粮。第2组和第3组分别以0.2%和0.4%的比例添加GP。在实验的最后一周，每组18只鸡(每个重复3只)用于代谢试验。在实验结束时，宰杀相同数量的禽类进行消化器官和屠体成分的测量。每个重复采血3只，分别于饲喂后第3、5、6周采血测定血脂水平。测定总胆固醇(Col)、甘油三酯(TG)、高密度脂蛋白(HDL)、低密度脂蛋白(LDL)水平。试验结果表明，GP对肉仔鸡增重、采食量(FI)、饲料转化率(FCR)、屠体切片、内脏器官无显著影响。而GP降低(P
This experiment was conducted to investigate the effect of feeding garlic powder (GP) on the performance, digestibility, digestive organs, carcass cuts and lipid profile of broilers. A total of 270 day-old Cobb-500 chicks were used in the experiment. Birds were partitioned into three experimental groups of 90 birds in each. Each treatment was composed of 6 replicates with 15 birds in each. The control group was fed with a commercial starter and finisher diet. The second and third groups were supplemented with GP at the rate of 0.2% and 0.4% respectively. In the last week of experiment, 18 birds from each experimental group (3 birds per replicate) were used in a metabolic trial. At the time of termination of the experiment, the same number of birds were killed for digestive organs and carcass components measurements. Blood samples from 3 birds per replicate were collected on 3rd, 5th and 6th week post feeding from wing vein for blood lipid profile determination. Total cholesterol (COL), triglycerides (TG), high density lipoprotein (HDL), low density lipoprotein (LDL) levels were determined. Results of this study showed that GP had no significant effects on broilers weight gain, feed intake (FI), feed conversion ratio (FCR), carcass cuts, visceral organs. However, GP decreased (P
