      crude protein degradability.

AB  - In situ rumen degradability of dry matter (DM) and crude protein (CP) in ruminant 
      diets composed of graded inclusion levels of marula nut meal (MNM) as a protein 
      source to replace soybean meal were evaluated. The five diets denoted as diet 1 
      (0.0 g kg(-1) MNM: control), diet 2 (45.5 g kg(-1) MNM), diet 3 (91.7 g kg(-1) 
      MNM), diet 4 (138.4 g kg(-1) MNM), and diet 5 (185.9 g kg(-1) MNM) were tested. 
      Three cannulated mid-lactating Holstein cows were used to incubate triplicate 
      subsamples of each diet for 2, 4, 8, 16, 24, and 48 h in polyester bags. The 
      soluble fractions of DM and CP increased (P < 0.05) with increasing levels of MNM 
      (138.4-185.9 g kg(-1) MNM). However, the insoluble but degradable fractions of DM 
      and CP increased (P < 0.05) with decreasing levels of MNM (45.5-0.0 g kg(-1) and 
      91.7-0.0 g kg(-1) MNM, respectively). While the degradation rate of fraction and 
      the effective degradability of DM increased (P < 0.05) with decreasing levels of 
      MNM (91.7-0.0 g kg(-1)), those of CP increased with increasing levels of MNM 
      (138.4-185.9 g kg(-1) MNM) in the diet. These results suggest that dietary 
      inclusion of MNM up to 91.7 g kg(-1) in ruminant diets can provide undegradable 
      protein to be absorbed in the small intestines and used for metabolic function, 
      while an inclusion of up to 185.9 g kg(-1) can be degraded in the rumen for 
      microbial protein synthesis.
