In Table 2 of the article by Morgavi et al. (2010), presented in Animal, some errors were inadvertently given in the ‘Fibre digestibility’ and ‘Acetate/propionate’ columns. The correct version of Table 2 is shown below. The authors apologise for any confusion caused.
Table 2 Effect of several additives on methane production, microbial populations, fibre digestibility and acetate/propionate ratio in rumen incubations in vitroFootnote a
Rfl = Ruminococcus flavefaciens; Ral = Ruminococcus albus; Fsu = Fibrobacter succinogenes; BCM = bromochloromethane; BES = bromoethanesulfonate.
a All the additives were added to batch mixed cultures in vitro except BCM 2 that was added to continuous cultures.
Cellulolytic bacterial species, methanogens and fungi were estimated by quantification of their rrs gene by relative quantitative PCR, except in the work of Wina et al. (2005) in which they were estimated by quantification of 16S RNA using dot blots, and in Guo et al. (2008), in which methanogens were estimated by PCR quantification of the mcrA gene.
Protozoa were quantified by cell counting or by rrs gene PCR quantification (only in Guo et al., 2008).
