Chapter 41. Faecal and ileal digestibility of casein- and soybean-based diets in growing pigs.

Abstract

A study was conducted to determine the effects of ileo-rectal anastomosis (IR) and protein source on apparent digestibility in growing pigs. Intact animals fed casein diet had significantly higher CP and NDF digestibilities than IR pigs. Intact animals fed soybean diet presented significantly higher DM, OM, CP, NDF, ADF and GE digestibilities than IR pigs. Intact pigs fed casein diet presented significantly higher DM, OM, CP, NDF and GE, and lower TL digestibilities than those fed soybean diet. IR pigs fed casein diet had higher DM, OM, CP, NDF, ADF and GE digestibility values than the ones fed soybean diet.
