国内外研究工作表明:海藻具有作为一种新的饲料资源的潜力。海藻资源丰富,其干物质中粗蛋白质含量为4.1～16.4％;粗纤维1.6～9.6％,矿物质为23.1～59.5％;含碘量高。海藻的主要碳水化合物可以被动物消化,但消化能和总消化养分(TDN)偏低,巳有的试验结果表明,海藻粉在饲粮中的用量,家禽5%左右;猪10％以下;绵羊15％以下;奶牛和肉牛20％左右,对生产性能无不利影响。将海藻作为畜禽饲粮的矿物质补充饲料使用也有效果。
Research work at home and abroad shows that seaweed has the potential as a new feed resource. Seaweed is rich in resources, the crude protein content of dry matter is 4.1 ~ 16.4%; crude fiber 1.6 ~ 9.6%, mineral 23.1 ~ 59.5%; high iodine content. The main carbohydrates of seaweed can be digested by animals, but the digestible energy and total digestible nutrients (TDN) are low. The experimental results have shown that the amount of seaweed powder in the diet, about 5% of poultry; pigs below 10%; sheep 15% or less; cow and beef cattle about 20%, no adverse impact on production performance. It is also effective to use seaweed as a mineral supplement for livestock and poultry diets.
