The use of kelp powder as a feed additive can reduce feeding costs and improve the quality of special animals: First, it feeds black chicken. Add 2%-4% kelp powder to the diet. The survival rate of chicks increased by 10%, and the weight gain of 280 grams at 10 weeks of age. Adding 5% of kelp powder to layer chicken feed increased the fertility rate of laying hens from 65% to 85%, and the hatching rate increased from 68% to 82%. The second is to feed pheasants. During the laying period of the pheasant, adding 2%-6% kelp powder to the feed can increase the egg production rate by about 15% and the iodine content in the egg yolk by 15 to 20 times. The third is to feed you. Adding 5% of kelp powder to the feed increases the egg production rate by 8%, the mortality rate by 10%, and the secondary egg rate by 8%, which can deepen the color of the egg yolk. The fourth is feeding Dutch pigs. Add 3% of kelp powder to the feed and raise for 60 days, the daily weight can be increased by 25%, and the feed conversion rate can be increased by 18%. In addition, the addition of 1% to 6% kelp powder to pigs, laying hens, ducks, quail, dairy cows, sheep and other livestock and poultry, has a very significant effect. The Institute of Amphibians and Reptiles of Haining City in Zhejiang Province used kelp powder in the feed of turtles, added 2% to 6% of kelp powder, increased egg production by 54%, increased the fertilization rate by 27%, and increased the growth rate of hatchlings and young turtles.
