The nutritional value of bovine bone meal is mainly reflected in calcium supplementation. Most of the commonly used calcium supplementation products are calcium tablets, and the main component of calcium tablets is calcium carbonate, which is relatively simple. Calcium supplementation is mainly to meet the needs of bones. The main components of human bones contain calcium and phosphorus. Scientific calcium supplementation requires a good ratio of calcium to phosphorus, which is beyond the reach of ordinary calcium tablets. The ratio of calcium to phosphorus in bovine bone meal is close to that of human body, and it contains certain protein components, which has obvious calcium supplementation effect and higher absorption rate than ordinary calcium tablets.
