This paper aims to investigate the effects of adding bran to swine feed on growth and health of pigs. Given the rising demand for pork and increasing concerns about animal welfare, this topic is particularly timely and significant. Bran, rich in dietary fiber, promotes the growth of beneficial gut bacteria, induces satiety, and alleviates stress in pigs. Compared to other agricultural by-products like straw, bran offers superior nutritional and energy values, making it an ideal addition to swine diets. For instance, rice bran, which has high crude protein and energy values, improves growth performance. Meanwhile, wheat bran, though lower in energy value, has a high soluble fiber content that increases beneficial intestinal bacteria in nursery pigs and reduces stress-induced inflammation. Soybean hulls, with their lower crude protein and energy values compared to rice or wheat bran, help prevent excessive fat accumulation during the fattening process, thus enhancing carcass characteristics and pork quality. Therefore, adding bran to swine feed improves the health, growth performance, and carcass quality of pigs, helping to meet market demands.
