Quality of food and voluntary intake of male impala (Aepyceros melampus) in the Timbavati area
… selected during different seasons, to determine intake and to convert this data into estimates of energy requirements which can be used when calculating carrying capacity for impala. These figures were compared to published estimates by Meissner et al (1983).

Application of Fecal Near Infrared Reflectance Spectroscopy and N-Alkane Labeled Supplementation Techniques to Predict Voluntary Intake in Beef Cattle
… supplementation method for the prediction of voluntary intake in beef cattle for the identification of animals divergent in feed efficiency. Additionally, the use of fecal NIRS profiling technology was evaluated for the prediction of diet characteristics. To examine the use of fecal NIRS …

Impacts of diet inversion on voluntary intake, digesta and fecal composition, and bacterial community composition in rumen of cattle fed tropical forage-based diets
… to evaluate the impact of the diet inversion on voluntary intake, ruminal digesta and feces composition, ruminal fermentation, and bacterial community composition in cattle fed tropical forage-based diest and to establish the minimal length of the adaptation period that could be applied to …

Digestibility and apparent mineral utilization by Arabian geldings fed alfalfa, tall fescue, and Caucasian bluestem
… higher (P < .01) dry matter digestibility, and voluntary intake, compared to grasses. Tall fescue and Caucasian bluestem did not differ in dry matter digestibility and voluntary intake. Feeding alfalfa resulted in higher (P < .05) intake and digestibility of CP and higher (P < .05) apparent …

Digestibility, intake and selectivity of three mixed-forage pastures by cattle
… treatment. Chemical composition, digestibility, voluntary intake, and selectivity of the forages were determined through use of esophageally cannulated steers and a rare earth marker (ytterbium). Forage intake appears to be most closely related to DM digestibility and content of the NDF and ADF …

The Effects of a Dietary Bacterial Protein on Mineral Balance in Rainbow Trout (S. gairdneri Rich.)
… were related to the growth of the fish, the voluntary intake of food by fish, and the mineral balance. Growth improved in fish fed diets containing 65% Pruteen and supplemented with 4% major-mineral mix containing calcium, magnesium, phosphate, iron, sodium, potassium and chloride. Calcium, …

Effects of fermentation products of silage on its intake by cattle
… have been implicated as factors limiting its intake by ruminant animals, although the contribution of individual chemical components is not clearly understood. A series of experiments were conducted to investigate the effect of short-term intra-ruminal infusions of silage fermentation end …

Fermentation, digestibility and palatability of ensiled broiler litter and corn forage
… the digestibility, nitrogen utilization and voluntary intake of the ensiled mixtures. The addition of broiler litter resulted in significant increases (P < .01) in dry matter, crude protein and ash for silages made from forage harvested at both maturities. Litter increased the crude protein …

Methodology for evaluating the digestibility and metabolizable energy of poultry feedstuffs
… dry matter and energy than others. By either a voluntary intake method or by a total collection method, values for the nitrogen-corrected metabolizable energy of corn were similar. The total collection method proved to be more reliable since it provided the least amount of variation when <u>ad …

The Suitability of Native Warm-Season Grasses for Equine
… objectives of this research were to 1) assess voluntary intake, toxicological response, and apparent digestibility of NWSG hays fed to horses; 2) evaluate the characteristics of three NWSG species under equine grazing; and 3) evaluate establishment strategies for NWSG and wildflowers in …

Effects of energy-protein supplementation frequency on performance of primiparous grazing beef cows during pre and postpartum
… evaluated at pre and postpartum period. Two 9-d intake-digestibility trials were performed throughout the experimental period where the first at 55 d before parturition, and the second at 55 d after parturition. Concentrations of glucose, IGF-1, NEFA, - OH, cholesterol and triglycerides were used …

Identifying nutritive, physical and volatile characteristics of oaten and lucerne hay that affect the short-term feeding preferences of lactating Holstein Friesian cows and Thoroughbred horses.
… example, it is important to avoid periods of low intake, as this can have immediate and sometimes longer-term consequences to animal performance. The daily rate of food intake is the single most important factor affecting animal performance and productivity (Illius et al. 2000) and an animal‟s …
