用含有5％、10％和15％的马尾藻组成的饲料饲喂肉用仔鸡,发现10％以内对肉用仔鸡的生长速度没有不良影响,但10％与15％的马尾藻饲料对饲料利用效率降低。只有5％的马尾藻组与对照组相近,10％和15％的海藻组均比对照组低。用3％的马尾藻粉代替微量元素添加剂,发现其生长速度和饲料利用效率均高于对照组,生长速率提高4.7—7.7％,饲料利用效率比对照组高3.2％—6.0％。马尾藻饲料组对仔鸡的成活率没有影响 Feeding chickens with 5%, 10% and 15% Sargassum flies did not have any adverse effect on the growth rate of broiler chickens within 10%, but 10% and 15% Reduced efficiency. Only 5% of the Sargassum group was similar to the control group, and 10% and 15% of the seaweed group were lower than the control group. With 3% Sargassum powder instead of trace element additives, the growth rate and feed utilization efficiency were found to be higher than the control group, the growth rate increased 4.7-7.7%, feed utilization efficiency was 3.2% -6.0% higher than the control group. Sargassum feed group has no effect on the survival rate of chickens
