Three experiments were conducted to evaluate the effects of diet and monensin on performance, digestibility, and methane production in steers fed forage-based diets. In Exp. 1, 72 individually fed steers (300 ± 25 kg) were used in a randomized block design arranged as 2 separate 2 × 2 factorials with two common treatments, thus 6 diets were fed with 12 steers per treatment. Factors included hig...

Potential competition between native and domestic herbivores is a major consideration influencing the management and conservation of native herbivores in rangeland ecosystems. In grasslands of the North American Great Plains, black-tailed prairie dogs (Cynomys ludovicianus) are widely viewed as competitors with cattle but are also important for biodiversity conservation due to their role in cre...

The forage maturation hypothesis (FMH) proposes that ungulate migration is driven by selection for high forage quality. Because quality declines with plant maturation, but intake declines at low biomass, ungulates are predicted to select for intermediate forage biomass to maximize energy intake by following phenological gradients during the growing season. We tested the FMH in the Canadian Rock...

Understanding forage quality and the factors that affect its constituents will help improve livestock production by making decisions that optimize forage nutritive value and intake. This investigation was conducted in Zagros semi-arid rangeland center, Iran to determine forage quality of several grass and legume species. Samples were collected at early bloom, from 5 m long and 0.10 m wide strip...

An in situ study (Exp. 1) using 4 ruminally cannulated steers (343 ± 11 kg of BW) in a completely randomized design was used to compare ruminal degradation characteristics of low-quality cool-season (C3; Kentucky bluegrass straw; Poa pratensis; 6.3% CP; DM basis) and warm-season (C4; tallgrass prairie; 5.7% CP; DM basis) forage. Four ruminally cannulated steers (252 ± 8 kg of BW; Exp. 2) and 4 ...

In New Zealand, agriculture is predominantly based on pastoral grazing systems and animal excreta deposited on soil during grazing have been identified as a major source of nitrous oxide (N2O) emissions. Forage brassicas (Brassica spp.) have been increasingly used to improve lamb performance. Compared with conventional forage perennial ryegrass (Lolium perenne L.), a common forage in New Zealan...

This paper presented summary of recently findings on Moringa oleifera (Mo) role in livestock dietetics and community’s livelihoods countries akin to Ethiopia. Relevant data were collected, analyzed, discussed, concluded recommended. Therefore, Mo is known be fast-growing high biomass-yield, drought-resistant multifarious potentials merited tropical forage-tree. said Panacea’ stores vital-nutrie...

The aim of this study was to evaluate the feeding behaviour indigenous goats and selection drivers different plant species in a Mediterranean forest rangeland. To achieve goal, seasonal variations terms forage availability quality ingested were studied during three grazing seasons. In same period, eight Beni Arouss breed selected explore changes their browsing behaviour. Forage determined by ha...

This study characterizes the changes in leaf mass, morphological composition and nutritional value of blades palisadegrass (Urochloa brizantha cv. Marandu) under continuous grazing first year implementation pasture after second eucalyptus planting an Integrated Crop-Livestock System Crop-Livestock-Forest, which were tested four seasons. The experimental design was random blocks, with three trea...

OBJECTIVE To analyze the sulfur content of water and forage samples from a geographically diverse sample of beef cow-calf operations in the United States and to estimate frequency and distribution of premises where forage and water resources could result in consumption of hazardous amounts of sulfur by cattle. DESIGN Cross-sectional study. SAMPLE POPULATION 709 forage samples from 678 beef ...
