... Thor tbe.measurement of basal metabolism,gbasal metaboIic~rate3, the animal must be in a thermoneutral environment`, ia ;postabsorptive .statc, resting, but conscious, quiescent,-and without stress. (There is difficulty determining when ruminant animals reach the postabsorptive state.)

... , although resting metabolic rate here is based on the previous month's average ambient temperature. The use of this temperature is necessary because cattle, unlike chickens, are usually exposed to widely fluctuating natural environments.

... The European Association for Animal Production adopted in 1964 the three-quarters power of body weight as the interspecies reference base (Mount, 1968~. Recognizing the many routes by which energy transfer can occur in animals, one can foresee that many factors influence HeE, such as prior plane of nutrition, rate of feed intake, environment, age, activity, disease and infec

... The greater resistance of light breeds to hot weather is partially explained by a reduced HeE (Burman and Snaper, 1965~. Minimizing the proportion of metabolizable energy expended for HeE would be advantageous in maximizing energy available for product synthesis.

... Such information has practical application in a consideration of alternatives for maximizing efficiency of energy expenditure for maintenance and weight gain in colder climates where shelter versus feed or fuel weigh heavily in farming budgets. Verstegen and Van der Hel (1974)
