In animals, including humans, free access to high-quality (generally energy-dense) food can
result in obesity, leading to physiological and health problems. Consequently, various …

A major part of the ME consumed by ruminants (MEI) is dissipated as heat. This fraction,
called heat production or energy expenditure (EE), is assayed largely by measuring O2 …

Metabolic profiles are widely used to monitor health, reproductive status and nutritional
status. In the last few years, the evaluation of oxidative stress has contributed increasingly to …

Numerous factors have the potential to affect the amount of forage or pasture eaten by
ruminant animals, including gut capacity, ability of tissues to metabolize nutrients, ruminal …

Tannins are widespread throughout the plant kingdom, occurring as hydrolysable and
condensed tannins and at different levels in several animal feeding sources. Recent years …

The ultimate goal of an organism is to maximise its inclusive fitness, and an important sub-
goal must be the optimisation of the lifetime pattern of food intake, in order to meet the …

Eighty continental crossbred beef heifers (414.9±37.9 kg of BW), 16 of which were ruminally
cannulated, were used in a 52-d experiment with a generalized randomized block design, to …

It has been hypothesised that, at non-limiting water oxygen conditions, voluntary feed intake
(FI) in fish is limited by the maximal physiological capacity of oxygen use (ie an 'oxystatic …

The hypothesis was tested that fish fed to satiation with iso-energetic diets differing in
macronutrient composition will have different digestible energy intakes (DEI) but similar total …

During the history of ruminant nutrition many factors have been proposed as regulators of
voluntary feed intake. In some cases, the implicit assumption has been that a factor acted …
