Effects of a recombinant fibrolytic enzyme on fiber digestion, ruminal fermentation, nitrogen balance, and total tract digestibility of heifers fed a high forage diet1

Abstract: A metabolism study was conducted using 8 ruminal cannulated beef heifers to investigate the effects of a recombinant fibrolytic enzyme (RFE; xylanase XYL10C) selected specifically for forage-fed ruminants on ruminal pH, fermentation, nitrogen balance, and total tract digestibility of heifers. The experiment was a cross-over design with 2 treatments and 2 periods. The 2 treatments were a basal diet containing 60% barley silage, 30% barley straw, and 10% supplement (DM basis) without (control) or with RFE. The e… Show more

“…It is generally accepted that increasing fibre degradation can improve fibre digestibility. Various fibrolytic enzymes have been widely applied to improve fibre degradation and nutritive digestibility of silages (Dehghani et al 2012;Romero et al 2015;Ran et al 2019). However, the use of commercial enzymes increases the cost of silage and their instability under acidic conditions further limits their application in silage production (Guo et al 2019).…”

“…due to the greater availability of nutrients, resulting from the improvement in rumen bacterial fermentation, as suggested by the general results found in the present study with supplementation with MAXFIBER®. However, there is still great variability in the answers about the effectiveness of enzymatic products that can be attributed to the animal's nutritional needs, lactation stage, diet composition, enzymatic activity, dose, and method of using the products (Ran et al, 2019).…”

“…Our research did not record substantive differences in the fiber digestibility of responses between control and treatment. As indicated by Ran et al (2019), this situation may have been due to ad libitum feeding of lambs.…”
