Kelp is a nutrient-rich marine plant containing amino acids, iodides, vitamins, minerals, and bioactive compounds that support animal growth. The essential elements found in kelp are typically present in an organic form, making them more easily absorbed by animals compared to inorganic minerals. As a result, incorporating kelp powder into animal feed can significantly enhance the nutritional profile of the diet, improve production performance, boost reproductive efficiency, and enhance the quality of meat and eggs. These benefits have been widely recognized and applied in practical livestock and poultry farming.
In terms of application, feeding sows with kelp has proven beneficial. For example, soaking 500 grams of kelp and chopping it, then mixing it with 50–100 grams of lard and boiling it into a soup, can be fed to sows once every 7–8 days during the first month after birth, and every 4–5 days in the second month. This practice can greatly increase milk production. Additionally, boiling 500–1000 grams of kelp in 2500–3000 grams of water and feeding the broth three times a day helps sows recover their appetite quickly post-birth.
For weaned piglets, adding 2% kelp powder to their base diet for 90 days has shown remarkable results. It increases daily weight gain by 23.6% and improves feed conversion efficiency by 13.22%. These findings highlight the potential of kelp as a natural and effective feed supplement that not only supports growth but also enhances overall productivity in animal farming. Its use aligns with modern trends toward sustainable and health-conscious agricultural practices.
