134. Effects of Former Food Products Inclusion on Nitrogen Balance and Nutrient Digestibility in Growing–finishing Pigs

Abstract

Abstract A metabolic trial was conducted to quantify the nitrogen (N) balance, the apparent total tract digestibility (ATTD) of nutrients, and the water consumption of growing-finishing pigs that were fed diets containing graded levels of former food products (FFPs). Twenty-four pigs were housed individually in metabolic crates and given ad libitum access to isonitrogenous, isoenergetic diets that were formulated with 0%, 20%, or 40% FFPs (as a replacement for conventional cereals). Each animal provided repeated measurements over two six-day collection periods, which occurred at the end of the grower (approximately 60 kg BW) and finisher (approximately 100 kg BW) phases. Daily feed and water intake was recorded. Total feces and urine were quantified each day, and samples were pooled for ch
