Relationships between voluntary intake of orchard grass and their chemical composition digestibility and digestible nutrient

Relationships between voluntary intake of orchard grass and their chemical composition digestibility and digestible nutrient

Grassland Science 25(2): 156-160

Pure swards of orchardgrass 'Phyllox,' 'Kitamidor' and 'St. Hokkaido' were harvested at the stages of maturity during first growth in the spring and in the subsequent regrowth. Each batch of harbage was fed to 5 wethers in a digestion trial under the condition of voluntary intake. Fresh orchardgrass samples (32) were used to evaluate the relationships between the voluntary intake (VI) and the chemical composition, digestibility and digestible nutrient. VI was significantly correlated with the contents of crude protein, acid detergent fiber, acid detergent lignin, digestibility of crude protein, cell wall (CW), dry matter, gross energy and the amounts of digestible crude protein, total digestible nutrient and digestible energy. VI was estimated as the ratio of fecal dry matter excretion to the percent of dry matter undigested. Fecal dry matter excretion (g/day per wt.0.75) of wethers in their full intake was .apprx. 22 g; this varied little between the 1st cutting in spring and aftermath. There was no significant correlation between VI and fecal dry matter excretion. Digestibility of dry matter: VI (r [correlation coefficient] = 0.70, P < 0.05) and indigestibility of dry matter: indigestible CW content (r = 0.93, P < 0.01) all have significant correlations. Indigestible CW evidently inhibit VI and voluntary digestible nutrient intake.
