There was a CaPr x Grain interaction in the volume of gas produced (V; p = 0.04). Addition of CaPr prolonged Lag time (1.4 vs. 1.04 h; P<0.01), and increasing the grain level also prolonged Lag time (1.56 vs. 0.89 h; p < 0.03) and gas production rate (0.046 vs. 0.041 h-1; P<0.04). However, there were no differences in CH 4 , CO 2 , acetate, propionate and butyrate concentrations. Therefore, the addition of calcium propionate in a diet with 55 or 66% of grain increased Lag phase but it is not affected fermentation pattern or methane losses. | URI: | http://ri.uaemex.mx/handle20.500.11799/79339 | Other Identifiers: | http://hdl.handle.net/20.500.11799/79339 | Rights: | info:eu-repo/semantics/Revista de la Facultad de Ciencias Agrarias info:eu-repo/semantics/openAccess http://creativecommons.org/licenses/by-nc-nd/4.0 |
