Pigs are prandial feeders and drinkers. Focus has been directed to pig nutritional needs that include micro- and macro-nutrients, mineral and vitamin requirements and feed particle size. Water is the most important nutrient for pigs without which pigs will only survive for a short time....

Increasing the efficiency of conversion of feed nitrogen (N) into milk and meat N in dairy cattle is an integral part of the effort to maintain or increase food production while decreasing agriculture's environmental impact. Mathematical models provide a means to assess and compare different...

Global tilapia production has been increasing in the last decade, with output doubling from 830 000 mt in 1990 to 1.6 million mt in 1999. Tilapia are very easy to culture and have the potential of becoming the prime freshwater species for culture. The ever increasing need for cheap sources of...

Recent research on the nutrient requirements of early weaned pigs is reviewed and the feeds that are available to provide these nutrients in a form that can be best utilized by the piglet are examined.

For most animals a choice of food materials is available, none of which provides a balanced diet if eaten alone, but from which such as diet can be constructed by appropriate selection. In order to make directed choices animals (including humans) must be able to differentiate between foods by...
