“…The lower digestibility of nutrients in 2006 relative to 2005 (P < 0.01) is difficult to explain. Yayota et al (2009) suggested that a decreased ruminal degradability in the fall could not be explained by the herbage ADL content alone; the results of the present study imply that an unidentified factor was involved. Further, investigations regarding foraging behavior of grazing cows are required to explain the difference of digestibility between years because selection of feeding sites, patches and plant species also affect chemical compositions and digestibility of their diet.…”

“…These data are consistent with results of our in situ study, suggesting that an increase in the ADL content prevents the ruminal degradation of dwarf bamboo (Yayota et al . ). At the beginning of the experiment, we assumed that grazing cattle could select favorable herbage from the extensive forestland pasture throughout the grazing season because of its sufficient availability and variation (Berry et al .…”

“…Second, the method for estimating apparent digestibility involves uncertainty if the experimental cows ingested a certain amount of soil; although the digestibility of the herbage fell within reported values for dwarf bamboo (Yayota et al . ) and native Japanese forages (NARO ). Finally, the estimated nutritional intake may not be accurate because of inaccuracies in the measurement of the nutritional composition and apparent digestibility of the sampled herbage.…”

“…One variety of dwarf bamboo known as Pleioblastus argenteostriatus f. glaber contains relatively large indigestible fractions such as lignin; this plant is therefore degraded in the rumen to a lesser extent than other common tropical grasses (Yayota et al . ). The nutritional characteristics of dwarf bamboo differ from those of the native grasses found in typical European alpine pastures and North American rangelands.…”

The nutritional status of cows grazing on a 120-ha public alpine forestland pasture dominated by the dwarf bamboo Sasa senanensis located in central Japan was evaluated over the course of 2 years. Data were collected during grazing seasons in three periods: early (June), mid- (August) and late (late September-early October) periods. During these periods, the number of experimental Japanese Black cows varied between three and six. With the exception of the dry matter (DM) intake in 2005 and the crude protein (CP) digestibility in 2006, the DM and CP intake and digestibility were lower in the mid- and late periods than in the early period for both years (P < 0.05). Metabolizable energy intake was slightly insufficient for the requirement of the cows in the late period of 2005; in the mid- and late periods of 2006, the metabolizable energy intake was 0.4 to 0.5 times the requirement. These results suggest that the energy intake of cows grazing on forestland pasture dominated by S. senanensis would not satisfy their requirements starting in the mid-period (August) grazing, even though the pasture had abundant herbage resources during these periods.

“…For starch, the pattern was opposite; there was a lesser amount of starch in summer than in winter. Yayota et al (2009) reported that the crude protein content in leaves from Pleioblastus argenteostriatus f. glaber exhibited no significant difference between spring and autumn. Nevertheless, dry matter and lignin contents were higher in the autumn while NDF content was higher in the spring.…”

Bamboo is an enigmatic forage, representing a niche food for pandas and bamboo lemurs. Bamboo might not represent a suitable forage for herbivores relying on fermentative digestion, potentially due to its low fermentability. To test this hypothesis, guinea pigs (n = 36) were used as model species and fed ad libitum with one of three forages (bamboo, lucerne, or timothy grass) in a fresh or dried state, with six individuals per group, for 3 weeks. The nutrient composition and in vitro fermentation profile of bamboo displayed low fermentation potential, i.e. high lignin and silica levels together with a gas production (Hohenheim gas test) at 12 h of only 36% of that of lucerne and grass. Although silica levels were more abundant in the leftovers of (almost) all groups, guinea pigs did not select against lignin on bamboo. Dry matter (DM) intake was highest and DM digestibility lowest on the bamboo forage. Total short‐chain fatty acid levels in caecal content were highest for lucerne and lowest for grass and bamboo. Bamboo‐fed guinea pigs had a lower body weight gain than the grass and lucerne group. The forage hydration state did not substantially affect digestion, but dry forage led to a numerically higher total wet gut fill. Although guinea pigs increased DM intake on the bamboo diet, the negative effects on fermentation of lignin and silica in bamboo seemed overriding. For herbivores that did not evolutionary adapt, bamboo as an exclusive food resource can be considered as inadequate.
