TSFP supplementation enhances pig and sow performance

Researchers from Taiwan investigated the effects of modified 2-stage fermented feather and soybean meal product (TSFP) on the performance, clinical blood biochemistry, and immunity of sows and piglets. Soybean meal is a high-quality protein source during late gestation and lactation periods of sows. However, it contains anti-nutritional factors such as glycinin and β-conglycinin. Feather meal comprises up to 85% crude protein with a low solubility and unbalanced amino acids. This limits its
