The energy metabolism was measured by means of indirect calorimetry in growing bulls with mean live weights of 290-420 kg and in wethers with mean live weights of 40-60 kg. The animals were fed 12 (bu...
In growing bulls (290-420 kg LW) and wethers (40-60 kg LW) the energy metabolism was measured by means of indirect calorimetry on 3 steps of energy intake (deposition, maintenance, underfeeding) as a ...
From 6 series of individual feeding experiments with different energy supply (EL = 1.1-1.8; EL = 538 kJ/kg LW0.75) the relationship between the intake of metabolizable energy and live weight gain empt...
On the basis of an analysis of energy metabolism measurements on adult pigs, fed on 92 ratios with very heterogeneous nutrient composition, the following prediction equations for gross energy (y1), di...
1. The effect of energy and protein intake on the nitrogen and energy utilization and carcass composition of artificially-reared pigs was studied between 8 and 32 d of age in an experiment employing a...
In this paper, we consider the control of energy balance in animals and man. We argue that patterns of mammalian feeding have evolved to control energy balance in uncertain environments. It is, theref...
(1) The energy content in food is used in the human body for three main purposes. The first is to maintain the dissipative structures. Most of the structures of the body are of this kind, i.e. they re...
BACKGROUND: Energy requirements during pregnancy remain controversial because of uncertainties regarding maternal fat deposition and reductions in physical activity. OBJECTIVE: This study was designed...
