Kelp is a nutrient-rich seaweed that contains essential amino acids, iodides, vitamins, minerals, and bioactive compounds that can stimulate animal growth. The nutrients found in kelp, especially trace elements, are 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 value of the diet. This not only improves the overall performance and reproductive efficiency of livestock and poultry but also enhances the quality of their products. These benefits have been successfully applied in practical farming scenarios, proving to be a valuable addition to modern feed formulations.
In swine production, kelp can be used to support sows during lactation. A recommended method is to soak and chop 500 grams of kelp, mix it with 50–100 grams of lard, and boil it into a soup. Feeding this mixture to the sow once every 7–8 days during the first month after birth, and then every 4–5 days in the second month, can greatly increase milk production. Alternatively, boiling 500–1000 grams of kelp in 2500–3000 grams of water and feeding the resulting soup three times a day can help sows recover their appetite and improve their overall health postpartum.
For weaned piglets, adding 2% kelp powder to their regular feed for 90 days has shown remarkable results. Studies indicate that this practice increases daily weight gain by 23.6% and improves feed conversion efficiency by 13.22%. These improvements highlight the potential of kelp as a natural and effective feed supplement that can boost productivity and economic returns in livestock farming.
By integrating kelp into feed formulations, farmers can promote healthier animals, better growth rates, and higher-quality outputs—all while using a sustainable and naturally rich ingredient.
