Liquid feeding creates an opportunity to recycle liquid residues from the human food industry as animal feed. Such residues are often low in dry matter and variable in composition. However, if diets are reformulated frequently to the account of such changes there is no loss of productivity and profitability can be increased. Modern luiquid feeding equipment facilitates frequent changes in diet composition, delivery of different diets to different pens of pigs and enables pigs to be fed at libitum or accurately rationed. These features provide an opportunity to use 'step' and 'phase' feeding regimes that can reduce the nutrient content of effluent and reduce environmental loading. Current research is investigating ways of increasing the efficiency of utilization specific raw materials by the targeted use of exogenous enzymes
