Use of the mobile nylon bag technique for determination of apparent ileal digestibilities of crude protein and amino acids in feedstuffs for pigs

Czech Journal of Animal Science, 2011
Three digestibility experiments were conducted to evaluate the potential of determination of apparent ileal digestibilities (AID) of crude protein (CP) and amino acids (AA) by the mobile nylon bag technique (MNBT) using 21 feedstuffs and three mixed ...

In situ evaluation of ruminal degradability and intestinal digestibility of extruded soybeans

Czech Journal of Animal Science, 2005
Two ruminally cannulated Jersey cows were used to determine in situ ruminal degradability and intestinal digestibility of raw (E0) soybeans and soybeans extruded at 145°C (E145), 155°C (E155) and 165°C (E165). The degradation of dry matter (DM) and crude
