Seasonal Variations in Voluntary Intake and Apparent Digestibility of Forages in Goats Grazing on Introduced Leymus chinensis Pasture
The nutrient composition of pasture, voluntary intake and digestibility of diet ingested by goats grazing on an introduced Leymus chinensis pasture were measured across spring (May), summer (July), autumn (October) and winter (March). In each season, 12 Inner Mongolian Cashmere goats (6 wethers and 6 does with an average live weight of 22.2±1.3 kg and 19.5±0.8 kg, respectively) were used to gra...
متن کاملThe Estimation of Pasture Intake by the Grazing Sheep
The few estimates in the literature of the quantity of food eaten by the grazing sheep have involved calculations based on some component of the faeces. ’ The “apparent digestibility” of this component was first calculated with sheep fed on known amounts of cut pasture. Faeces were then collected from grazing sheep and the amount of the particular component in the faeces was used to predict the...
متن کاملEffects of Grazing and Mowing on Leymus Chinensis Grassland in the Songnen Plain of Northeastern China
Effects of mowing and grazing on a Leymus chinensis grassland in the Songnen plain of northeastern China were studied using eight replicates of four grazing and mowing treatments. Canopy cover and biomass of the dominant species (L. chinensis) were lower, and cover of the halophyte Suaeda corniculata higher, on grazed than ungrazed; ungrazed plots showed a response to mowing, but not grazing; s...
متن کاملEstimates of the Intake and Digestion of Nitrogen by Sheep Grazing a Mediterranean Pasture as It Matures and Senesces
The level of production by sheep that graze a Mediterranean pasture as it matures and senesces depends on diet selection. By estimatin, 0 diet selection under these conditions using 2 methods, we predict that the intake of nitrogen (N) and amount of N apparently digested (ADN) decreases as the pasture matures and senesces, but that it decreases at a slower rate than the decline in pasture N con...
متن کاملSeasonal changes in the digesta-adherent rumen bacterial communities of dairy cattle grazing pasture
The complex microbiota that resides within the rumen is responsible for the break-down of plant fibre. The bacteria that attach to ingested plant matter within the rumen are thought to be responsible for initial fibre degradation. Most studies examining the ecology of this important microbiome only offer a 'snapshot' in time. We monitored the diversity of rumen bacteria in four New Zealand dair...
