Cattle owners consistently underestimated the weights of their cattle; 85.7% of the cattle had their bodyweights underestimated by an average of 46.9% of their true weight. Furthermore, very few cattle (19.0%) had their weights estimated accurately to within 卤20% of their true weight by these...

A series of liveweight gain (LWG), feed and water intake and digestibility experiments were conducted across eastern Indonesia. Thirty-six datasets of LWG, feed and water intake, and diet characteristics were used to determine the nutritional requirements of growing Bali cattle fed a wide range of...

A RE-EXAMINATION of the work of Hammond 1 , Wallace 2,3 , Pálsson and Vergés 4,5 and Wardrop 6 , suggests that the carcass composition of a sheep, in terms of dissected bone, muscle and fat, is more closely related to its live weight than to its age. Using all the available data...
Grazing and stall-feeding experiments were conducted to examine the effect of giving different amounts of cereal-protein concentrate with grass on the live-weight gain of cattle initially 6 months of age. The effect of level of concentrate on grass intake was also studied in the indoor trial. ...
