Title

COMPARISON OF IN VIVO WITH IN SITU MOBILE BAG AND THREE STEP ENZYMATIC PROCEDURES TO EVALUATE PROTEIN DISAPPEARANCE OF ALFALFA HAY AND BARLEY GRAIN

Pages

  260-266

Abstract

 Ruminal, post-ruminal and total tract crude PROTEIN DISAPPEARANCE of alfalfa hay and barley grain were measured using IN VIVO, in situ MOBILE BAG and three-step in situ/in vitro enzyme procedures (3-step). For IN VIVO, four Baluchi lambs (49.4±3.5 kg, body weight) were used in a 2×2 Latin square design within 2 periods (24 days of each period). Experimental diets were made of two alfalfa hay: barley grain ratios (DM basis) as 1.0:0.0 and 0.5:0.5. Diets were fed to animals for 24 days, with 7 days of feces collection. In situ MOBILE BAG technique was followed by 12 h rumen incubation and then intestinal movement of the bags in rumen and post-rumen cannulated Holstein steers. The three-step procedure was followed by rumen incubation of samples for 12 h (using polyester bags) and enzymatic incubation of ruminal undegradable samples. IN VIVO total tract crude PROTEIN DISAPPEARANCE of alfalfa hay and barley grain (0.74 and 0.69, respectively) was significantly (P<0.01) lower than in situ mobile nylon bag (0.89 and 0.96, respectively) and the 3-STEP PROCEDURE (0.81 and 0.89, respectively). Total tract crude PROTEIN DISAPPEARANCE from in situ MOBILE BAG was significantly (P<0.01) higher than the 3-step technique. Post-ruminal disappearance of ruminal undegradable crude protein from alfalfa hay and barley grain using in situ MOBILE BAG method (0.69 and 0.86, respectively) was significantly (P<0.01) higher than the 3-step enzymatic method (0.49 and 0.56, respectively). Results of the present study showed that there was a significant difference between IN VIVO, in situ MOBILE BAG and 3-step methods when total tract crude PROTEIN DISAPPEARANCE of barley grain and alfalfa hay was evaluated.
