【摘要】 本项研究在调查我国海藻资源量,分析其化学成分的基础上,用40头生长肥育猪、800只产蛋鸡、3000只蛋鸭及3900只肉鸭做了共5次饲养试验以及生产应用观察。结果表明:海藻粉以适当比例加到饲粮中能改善饲粮适口性,增进采食量,并明显提高畜禽生产性能及繁殖能力。加入2％的海藻粉可使生长猪增重速度提高12％,使蛋黄含碘量增加10倍。海藻粉在畜禽饲粮中的用量以2—5％为宜。更多还原

【Abstract】 Forty growing-fattening pigs, 800 laying hens, 3000 laying ducks and 3900 broilers were used in 5 feeding experiments. The results showed that marine algae when incorporated in animal and poultry diets in suitable proportions could improve palatability, increase feed intake and enhance productivity and reproductivity. Incorporation of 2 % marine algae meal in diet could increase daily gain 12% and the iodine content of yolk 10 times. Supplementation of 2-5% in animal and poultry diets were recommended.更多还原
