A study conducted by the National University of Colombia has found that bovine whey can help reduce the need for antibiotics in pig farming during the post-weaning stage. The study involved 48 Landrace x Yorkshire crossbreed pigs and found that the inclusion of bovine whey in the diet led to similar daily weight gain as antibiotics used as growth promoters. The study suggests that whey can help promote the development of the digestive system and improve the use of nutrients in pigs.
