“…Previous studies of yak energy balance have been based on confined animals (Han et al, , 1993Hu et al, 1992aHu et al, , 1992b. A method for measuring heat production (HP) in grazing animals has been presented and evaluated in beef cows by Brosh et al (1998Brosh et al ( , 2002Brosh et al ( , 2004, and (Brosh, 2007). This method was also used in this study of grazing yaks on the Qinghai-Tibetan plateau.…”

“…Any variation in the pulse rate is an indicator of stress, movement, exertion and disease. The average pulse rate of an adult healthy cow is 48 to 86 beats per minute [18,20]. Heart pulse measurement is an indirect method of the measurement of health.…”

“…Rumination is the function of how well animal is resting and what they eat. Veterinarians require rumination monitor because rumination data can provide them accurate data of animal's wellbeing [20][21]. We are going to use an ADXL335 Triple-Axis Accelerometer Module to measure rumination of the cattle which could be fitted on the mouth of the cattle [22].…”

“…Energy expenditure has also been estimated from measurements of heart rate and O 2 consumption (Brosh et al 1998;Brosh 2007). However, the relationship between EE and heart rate must be determined for the diet consumed at the time the O 2 pulse is determined (Brosh et al 2002). Also, basal heart rate differs among individuals (Derno et al 2005).…”

“…Another technique utilized to estimate EE is the respiratory gas exchange method, which measures O 2 consumption and CO 2 production in tracheostomized animals (Whitelaw 1974). Problems encountered with this technique relate to the use of tracheostomized animals, which is expensive, has limitations in field application, creates animal welfare considerations and disrupts normal animal behaviour (Brosh et al 2002).…”

. 2008. Estimation of carbon dioxide production and energy expenditure of grazing cattle by the sulphur hexafluoride (SF 6 ) tracer gas technique. Can. J. Anim. Sci. 88: 651Á 658. The purpose of the study was to explore the suitability of the sulphur hexafluoride (SF 6 ) tracer gas technique to estimate CO 2 production and energy expenditure (EE) for grazing animals on pastures typical of western Canada. During each year of a 3-yr study, CO 2 emissions were collected from 60 yearling steers on grass pastures receiving one of three fertility treatments: no manure, liquid hog manure applied as a split application (74 kg available N ha(1 ) in the spring and fall, and a single application of liquid hog manure applied at a rate of 155 kg available N ha(1 each spring. The mean CO 2 production estimate across all treatments was 542492218 L d(1 (mean9SD) with a range of 1099 to 11548 L d(1. When compared across three grazing periods in June, July and August, steers produced more (PB0.05) CO 2 in June than in either July or August. Metabolic body weight (BW 0.75 ), average daily gain (ADG), standing forage biomass, and forage neutral detergent fibre (NDF) and crude protein (CP) contents explained 33% of the variation in CO 2 production. Energy expenditure (EE) was estimated from CO 2 production by adopting an energetic equivalent of 22 kJ L(1 CO 2 and EE was calculated for animals that were not losing body weight at time of measurement. The average EE estimate was 1.290. . Energy expenditure declined as ADG and forage biomass declined, but EE was not influenced (P0.05) by fertility treatment. The EE estimate was higher (P B0.05) early in the grazing season (June) and declined as the grazing season progressed. The SF 6 tracer gas technique was able to estimate EE of individual animals without interfering with herd dynamics. The technique was also able to show differences in EE in response to pasture conditions. The results of this study suggest that the SF 6 tracer gas technique shows potential as a simple and non-invasive method of estimating CO 2 production and EE for grazing animals. Further validation under different grazing conditions and with animals undertaking different degrees of activity is required. Comparisons with other field techniques of estimating EE are also important.Key words: Energy expenditure, carbon dioxide, sulphur hexafluoride, grazing animals Stewart, A.
