Understanding potential impacts of vegetation change on caribou energetics requires information on varia¬ tions in forage quality among different plant types and over time. We synthesized data on forage quality (nitrogen, neutral detergent fiber and dry matter digestibility) for 10 plant growth forms from existing scientific literature and from field research in the Arctic National Wildlife Ref...

Forage fish support the largest fisheries in the world but also play key roles in marine food webs by transferring energy from plankton to upper trophic-level predators, such as large fish, seabirds, and marine mammals. Fishing can, thereby, have far reaching consequences on marine food webs unless safeguards are in place to avoid depleting forage fish to dangerously low levels, where dependent...

Fenugreek is being developed as a forage legume crop in western Canada, as it has desirable agronomic and forage quality traits. The objective of the present study was to determine if genotype x environment interactions have an impact on seed and forage yield when plants are grown under the short growing season of western Canada. Two studies were conducted: one with up to 83 accessions grown un...

A feedlot growth-performance trial and a metabolism trial were conducted to evaluate the interaction of forage level (10 vs 20%) and monensin (0 vs 28 mg/kg, air-dry basis) on utilization of a steam-flaked corn-based finishing diet. There were no treatment interactions (P > .10) on feedlot cattle growth performance or site and extent of digestion of OM, ADF, N, and starch. Monensin supplementat...

Forages are the foundation for building diets for beef and dairy cattle, horses, sheep and goats. The quality of these forages directly impacts forage intake, animal performance, and, ultimately, the profitability to their owners. As the quality of forages decline, consumption of that forage decreases and the amount of grain or byproducts which must be fed increases. The cost for a unit of perf...

This article summarizes the development of wireless strain sensing systems for a variety of customer driven structural health monitoring (SHM) applications. By combining advanced, low power microprocessors, flexible software operating modes, and low power signal conditioners, these systems were optimized for very low power operation, while permitting high speed data logging and wireless communi...

Railway traction is a more stochastic heavy load connected system. Due to the usage of ac-dc converters and ac-ac converters, the various power quality issues become the major problems in the electric system. This paper presents a review on power quality conditioners suitable for Railway traction based on the configuration, components involved and on the technical and economic considerations. M...

spp.) showed that forage DM intake was positively correlated with N fertilization rate. Fertilization may also Because native, shortgrass prairies are not typically fertilized and increase forage preference by livestock. Cook and Jeffotherwise extensively managed, little information is available on their response to nitrogen (N) fertilization. An experiment was conducted eries (1963) showed tha...

The forage m atu ra tion hypothesis (FM H ) proposes th a t ungulate m igration is driven by selection for high forage quality. Because quality declines w ith p lan t m atu ra tion , bu t intake declines a t low biom ass, ungulates are predicted to select for interm ediate forage biom ass to maximize energy intake by following phonological gradients during the growing season.
