This study with grazing beef cows on the range was designed to explore the possibility of determining incremental energy expenditure (EE) in standing, traveling, and grazing relative to that in lying down, by means of continuous monitoring of EE, location, and activity by the heart-rate method, with Global Positioning System (GPS) collars, and by motion sensors in the GPS collars, respectively. Cows were observed on Mediterranean foothill rangeland covered with herbaceous vegetation through 4… Expand
Energy cost of activities and locomotion of grazing cows: a repeated study in larger plots.
TLDR
Estimated cost coefficients of standing, grazing, and horizontal locomotion derived from animals on relatively larger plots were similar to those of the previous study based on data from smaller plots, but the energy costs of walking idle and of vertical locomotion were greater in the present study than in the previous one. Expand
Grazing behavior and energy costs of activity: a comparison between two types of cattle.
TLDR
The grazing behavior, diet intake, and energy costs of activity of 2 types of cows grazing a Mediterranean pasture were compared and smaller framed Ba cows grazed more hours per day and walked longer distances than the BM cows among all seasons. Expand
Estimation of the energy expenditure of grazing ruminants by incorporating dynamic body acceleration into a conventional energy requirement system.
TLDR
The use of the VeDBA appears to be a precise way to predict activity-specific EE under grazing conditions, and the method incorporating acceleration index data with a conventional energy system can be a simple and useful method for estimation of EE in farm ruminants on pastures. Expand
Energy cost of the activities of grazing cows,effect of plot size
TLDR
It is suggested that on larger plots cows could select herbage of better quality than when grazing smaller plots when grazing in winter, when the herbage was dry. Expand
The energy expenditure of 2 Holstein cow strains in an organic grazing system.
TLDR
The aim of the present study was to compare EE, which can be affected by differences in body weight, body composition, grazing behavior, physical activity, and milk production level, in 2 Holstein cow strains, and to investigate the determining factors for EE. Expand
Application of Overall Dynamic Body Acceleration as a Proxy for Estimating the Energy Expenditure of Grazing Farm Animals: Relationship with Heart Rate
TLDR
The results indicated that ODBA is a good proxy for estimating the energy expenditure of grazing farm animals across species and breeds, and the utility and simplicity of the procedure with acceleration loggers could make the accelerometry technique a worthwhile option in field research and commercial farm use. Expand
Foraging behavior of two cattle breeds, a whole-year study: I. Heat production, activity, and energy costs.
TLDR
The foraging behavior and energy costs of activity of 19 large-frame Beefmaster × Simford (BS) cross mature cows and 14 small-frame Baladi (BA) mature cows was determined and metabolic rate of BS cows was greater in conditions of high herbage quality. Expand
Invited review: feeding behavior of goats.
TLDR
These methods create the opportunity to gain a fuller understanding of factors influencing the feeding behavior of goats and the relationships with levels and efficiencies of production. Expand
Grazing Behavior and Locomotion of Young Bulls Receiving Different Nutritional Plans in a Tropical Pasture
TLDR
It can be concluded that the use of activity sensor methods can be recommended due to their being similar to visual observation and able to record 24-h/d and while supplements with high carbohydrates reduce pasture intake, they do not change grazing behavior. Expand
Factors influencing estimates of heat energy associated with activity by grazing meat goats
Abstract Ten yearling Boer goat wethers (45.4±0.92 kg) grazed a 0.8-ha grass pasture or were individually confined in a crossover experiment with 3-wk periods to evaluate factors influencing heatExpand

Goats locomotion energy expenditure under range grazing conditions: seasonal variation.
TLDR
Grazing and walking were the primary activities of goats throughout the study and the energy expenditure of locomotion was calculated from the horizontal and vertical components of travel and the corresponding costs, which had been previously obtained by calorimetry. Expand
Seasonal variation of locomotion and energy expenditure in goats under range grazing conditions.
Energy cost of various activities can be used in conjunction with direct field observations to estimate energy expended in the daily activities of free-ranging animals. The objective of this studyExpand
Energy balance of grazing beef cattle in Mediterranean pasture, the effects of stocking rate and season: 2. Energy expenditure as estimated from heart rate and oxygen consumption, and energy balance
TLDR
The HR, EE and retained energy (RE) were highly correlated with MEI (P), and the diurnal and annual EE patterns were affected mainly by the herbage quality and intake. Expand
Estimation of energy expenditure from heart rate measurements in cattle maintained under different conditions.
TLDR
HR, a relatively easy measurement, can be useful and accurate in estimating energy expenditure in cattle, and the relationship of HR to EE should be established for each animal to increase the accuracy of the estimation of EE by HR. Expand
Measurements of energy balance of grazing beef cows on Mediterranean pasture, the effects of stocking rate and season: 1. Digesta kinetics, faecal output and digestible dry matter intake
Abstract Intake and digesta kinetics of free-ranging beef cows in two stocking rates were estimated during the course of the grazing seasons, February through June 1998 and 1999. Area allocationsExpand
Energy expenditure of cattle grazing on pastures of low and high availability
TLDR
It was concluded that the increase in energy expenditure of cattle due to the activity of grazing depends on the rate of biting, and grazing for 10 h at a moderate rate may boost EE proportionately by only 0·06, however grazing at the highest rates could easily add proportionately 0·20. Expand
Energy expenditure estimation from heart rate: validation by long-term energy balance measurement in cows
TLDR
It is concluded that energy expenditure of beef cows during the reproductive cycle can be calculated from HR and O 2 pulse and the combination of EE and MEI measurements enables estimation of the feed energy available for production by non-constrained cattle. Expand
Energy Expenditure by Heifers Grazing Crested Wheatgrass of Diminishing Availability
TLDR
The purpose of this study was to measure the energy expenditure of grazing heifers at several different levels of available forage, and to compare these quantities to the energy expended by similar stall-fed animals consuming a diet of similar quality and quantity. Expand

Inference of Animal Activity From GPS Collar Data on Free-Ranging Cattle
TLDR
It is found that distance alone is a poor indicator of animal activity, but grazing, traveling, and resting activities of free-ranging cattle can be inferred with reasonable accuracy from data provided by Lotek GPS collars. Expand
