Ruminal degradability of shell of pods of the lima bean (“Phaseolus lunatus” L.) ammoniated with urea

SUMMARY This study aimed to evaluate the dry matter, crude protein and neutral detergent fiber ruminal degradability of shell pods of lima bean (Phaseolus lunatus L.) ammoniated with four levels of urea (0; 2; 4 and 6% in dry matter basis). Three adult cattle Girolando breed, with 400±5,3kg of body weight fistulated with ruminal cannula were utilized. Ammoniation of shell of pods of the lima bean as 6% urea resulted in higher crude protein content (15.7%) of shell pods and degradability of crude protein (91.7%). Potential degradation of dry matter increased (P
