Spatial Allocation of Forages and Its Impact on Grazing Behavior, Diet Selection and Dry Matter Intake of Beef Steers
… has shown that ruminants will select a mixed diet. The use of adjacent monocultures is an essential tool for determining dietary preference of forages. Much of the work to date has been conducted with white clover (Trifolium repens L.) and perennial ryegrass (Lolium perenne L.). Partial …

Habitat use, feeding ecology and the impact of re-introduced elephants (Loxodonta africana) on trees within a restricted conservation area in the semi-arid, Little Karoo, South Africa
… to determine the home range, habitat use and diet selection of the herd of re-introduced elephants and to document their impact primarily on the key tree species in the reserve. It was found that the home range of these animals was considerably smaller than expected (26 km2) and was strongly …

Age-related changes in taste and gustatory response and feeding behaviour in the stabled horse
… decisions relating to both short and long term diet selection and thus, any compromise in function, has implications for food intake and potentially welfare. The principal aim of this study was to establish if, and to what extent, taste andgustatory responses are affected by age in the horse. …

Fecal Bacterial Communities as an Indicator of Trophic Interactions Among Anuran Larvae
… potential to be used as indicators of changes in diet making it possible to determine if tadpoles in the wild are eating the same food or not. After feeding on two prepared diets that differed in the percentage of complex carbohydrates, the fecal bacterial communities of tadpoles were not …

Understanding the complex relationships between climate, vegetation, and foraging behavior of a climate-sensitive alpine mammal in order to explain patterns of persistence
… indicators of forage quality, driving winter diet selection, especially in high elevation areas with extreme seasonality. Nutritional components, such as protein, nitrogen, and water content, are more important to summer diet. Foraging selectivity for nutritional components changes in response …

Influence of dietary nutrients on life history-related traits of black flies and mosquitoes
… in sugary food sources can influence the food selection pattern of dipteran vectors and potentially confound the outcomes of field trials on the efficacy of entomopathogenic bacteria as vector control agents. Further, nutrient components of bacteria-inoculated artificial diets may present …

Juvenile Green Turtle (chelonia Mydas) Foraging Ecology:feeding Selectivity And Forage Nutrient Analysis
… preference by comparing prey items in the diet to the availability of those items in the habitat, 2) identify species for which there was selection or avoidance, 3) identify nutritional factors determining selection or avoidance of prey items, and 4) evaluate the nutritional content of the …

Genetic polymorphism of alpha s1-casein. Feeding strategies to optimize productive performances of dairy goat with different genotype.
In literature, the effects of diet and alpha s1-casein genetic polymorphism on the productive performances of dairy goat are discussed separately. Besides to cover a lack of scientific knowledge on this topic, we think that to study the effect of interaction between dietary and genetic factors on …

Feeding habits of the yellowtail flounder and production of its invertebrate prey on Georges Bank
… are the most important prey groups. Although the diet composition varied among stations and dates, in each case a few prey species constituted the bulk of the diet. Selection indices were calculated to compare the species composition of the stomach contents to that of the benthic macrofauna. Food …

Evaluation of Bison (Bison Bison) Ecology at the Olson’s Bison Conservation Ranches, Pine River Ranch, Manitoba, Canada
… forage availability and determine bison diet composition to understand forage selection (Chapter 1), 2) calculate biomass production and estimate carrying capacity of bison (Chapter 1), 3) calculate bison neonatal survival and determine cause-specific mortality (Chapter 2), and 4) examine …

Influence of endophyte infection of tall fescue with and without white clover on performance, intake, and bite size in steers during the grazing season and subsequent performance in the feedlot
… all animals were finished on a high corn silage diet and slaughtered. Daily gains of steers grazing low endophyte-infected pastures were higher (P<.01) than for those grazing high endophyte-infected pastures. Cattle grazing high endophyte-infected tall fescue with clover at Glade Spring gained at …
