Descriptions
Twelve grazed steers of Japanese Black Breed, eight months old, weighing approximately 200kg, were divide into two groups, namely Lot A and Lot B. The steers belonging to Lot A received concentrates of 1.0-1.2 % of body weight. The steers in Lot B received half as much.
Energy expenditures were measured indirectly using beatmeter with two steers from each lot, once in every month through 24 hours.
Average daily energy expenditure of the steers from May to October was 39 Cal/kg・day. It is 30% higher as compared with 30 Cal/kg・day for adult cows.
Energy expenditures per kg body weight per hour in grazing and loafing forms were only slightly higher in young steers than in adult cows, while in resting and ruminating forms they were three times as much in the young steers.
