The relationships between the cellulose-lignin complex, voluntary consumption and dry-matter digestibility were examined using forages of two varieties of Italian ryegrass and two legumes, lucerne and sainfoin. These forages had previously been shown to exhibit different intake-digestibility relationships. The cellulose, acid detergent lignin and acid detergent fibre contents of these forages as well as their digestibility coefficients were determined. Lignins were extracted from the fibre fractions and their ultraviolet difference spectra determined.Changes in maturity of a forage during a single growth phase, produced changes in dry-matter digestibility which were closely associated with changes in the digestibility of the cellulose and inversely related to the lignin content of the forage. Differences in digestibility between varieties of forage were less closely associated with lignin content. As the grasses matured a lignin fraction forming a difference peak at 350 m/t became evident and this was associated with decreased cellulose digestibility.Differences in voluntary food consumption resulting from changes in maturity of a single forage variety, in one growth phase, were also closely correlated with both dry matter and cellulose digestibility and inversely with lignin content. Differences between varieties and growth phases of the ryegrasses and between grasses and legumes were related less to the nature of the cellulose-lignin complex and more closely to the percentage of the total digesta deriving from cellulose.Sainfoin was characterized by the formation post-ruminally of an artifact that analysed quantitatively as lignin and qualitatively resembled a non-conjugated phenolic lignin fraction. The production of this artifact apparently disturbed fibre digestibility estimates and may have affected dry-matter digestibility estimates. Degradation of lignin apparently occurred both in the rumen and in the hind gut.

The nutritional value of plant fodder, daily consumption, and digestibility of forage were assessed in an isolated group of free living (wild) horses inhabiting the pastures of Vodnyi Island during different sea sons of 2010-2011. The digestibility was determined by the proportion between inert food components (sil icon, lignin) in the diet and the feces. The daily intake of food was calculated according to the weight of the daily feces and digestibility of food. Daily food consumption of the free living horses during the snowless period is from 8 to 14 kg/ind. and 16 kg/ind. (dry weight) during the winter period. Food digestibility changes from 49 to 54% per year; the mean digestibility is 52%. The daily metabolic energy intake during the snowy period of the year (130.7 MJ/ind.) is almost twofold higher than in spring (67.4 MJ/ind.). In all the seasons, it exceeds the requirements for energy. The free living horses of Vodnyi Island have parameters of digestibility and consumption of forage similar to other horses.
