Description
André Martinho de Almeida and co-authors tested lower protein diets for finishing pigs in a 2024 study. Cutting crude protein saves feed cost and cuts nitrogen waste. Added amino acids can fill the gap for growth. The team worked with heavy Duroc cross pigs in the final finishing stage.
Sixty male and sixty female pigs were split into pens by sex. For forty-two days, groups got either a standard diet or one with less protein plus amino acids. Growth, carcass traits, meat quality, and nitrogen balance were tracked. Sex and diet effects were tested apart and together. Results guide greener, cheaper pork production.
