FUENTE, G. de la; BELANCHE, A.  and  FONDEVILA, M.. In vitro ruminal fermentation of carbohydrates by spanish ibex. Arch. zootec. [online]. 2009, vol.58, n.223, pp.357-362. ISSN 1885-4494.

The 48 h fermentation pattern of pectin, xylan and cellulose from rumen contents of males (MM), females (MH) and kids (MJ) of Spanish Ibex (SI) and from domestic goats (CD) was studied. There were no differences (p>0.05) among SI inocula in total gas production at any incubation time. Gas volume was higher (p<0.05) with all SI inocula than with CD, from 6 to 30 h, from 6 to 16 h and from 24 to 36 h with pectin, xylan and cellulose. The maximum rates of fermentation (ml/g per h) were manifested earlier and more abruptly for SI inocula with all substrates. Fermentative activity of rumen
