This work aimed to assess the impact of timing of herbage allocation and fasting on patterns of ingestive behavior, herbage intake, ruminal fermentation, nutrient flow to the duodenum, and site and extent of digestion. Treatments were daily herbage allocation in the afternoon (1500 h, AHA), morning (0800 h, MHA), AHA after 20 h of fasting (AHAF), and MHA after 20 h of fasting (MHAF). Four rumin...

The more diversified in habits and structure the descendants of our carnivorous animal became, the more places they would be enabled to occupy. What applies to one animal will apply throughout all time to all animals. . . So it will be with plants. It has been experimentally proved, that if a plot of ground be sown with several distinct genera of grasses, a greater number of plants and a greate...

The butanol-HCl spectrophotometric assay is widely used for quantifying extractable and insoluble condensed tannins (CT, syn. proanthocyanidins) in foods, feeds, and foliage of herbaceous and woody plants, but the method underestimates total CT content when applied directly to plant material. To improve CT quantitation, we tested various cosolvents with butanol-HCl and found that acetone increa...

unshaded sites in southern USA when exposed to high summer temperatures (Van Santen and Sleper, 1996). The design of agroforestry systems requires a thorough understandNeither orchardgrass nor tall fescue had significant ing of biological interactions that might complement or constrain yield reduction in pots exposed to 50% shade, and orproduction. The objective of this study was to examine eff...

white clover is positively correlated with increased size of plant parts and reduced leaf density per unit area The plasticity of white clover (Trifolium repens L.) results in (Beinhart et al., 1963). changes in plant habit in response to different environmental stresses. The objective of this research was to characterize those morphological Defoliation through grazing or clipping is a managech...

Understanding the impact of changing pasture composition on reducing emissions of GHGs in dairy grazing systems is an important issue to mitigate climate change. The aim of this study was to estimate daily CH₄ emissions of dairy cows grazing two mixed pastures with contrasting composition of grasses and legumes: L pasture with 60% legumes on Dry Matter (DM) basis and G pasture with 75% grasses ...

Information that is presently available makes chemical control of sagebrush (Artemisia’ tridentata) a practical operation. Yet additional information is needed regarding ecological responses to assure that the practice of spraying for sagebrush control will be used wisely. The economy of brush control must be determined by the amount of forage and meat products gained; however, the principal ob...

in the present study basal area and importance value index (ivi) attributes of herbage were investigated in chir pine (pinus roxburghii sargent) stands of three different ages and also in open grassland in the sub-tropical region of himachal pradesh (india) during growing season (june to september). a higher basal area of the herbage was recorded in open grassland as compared to chir pine stand...
