Ten samples of each fibrous feed were mixed with ZAD® (mixture of cellulases, xylanaxes, proteases and alpha amylase). ENZ was added at 0, 1 and 3 L to one ton of the fibrous feeds and the mixture was ensiled for 30 days. Feed samples were incubated for 72 h in rumen liquor of sheep to determine the degradability of DM, NDF and ADF. Pretreatment of feeds and their mixture (RS and DDGS) with ENZ at 3 L were increased (P<0.01) the degradation of NDF and ADF. Degradation fractions (a, b, (a+b) and c) of feeds were improved (P<0.01) at 3 L of ENZ, except the c of NDF and ADF of RS which were not affected by ENZ treatment. The results suggested a strong potential in improving digestion of RS and DDGS as well as their mixture with the pretreatment with ENZ. The dose of 3 L/ton of fibrous product improved the DM, NDF and ADF degradability. | URI: | http://ri.uaemex.mx/handle20.500.11799/66005 | Other Identifiers: | http://hdl.handle.net/20.500.11799/66005 | Rights: | info:eu-repo/semantics/openAccess http://creativecommons.org/licenses/by-nc-nd/4.0 |
