Abstract

In a 3 X 2 factorial design of experiment 96 growing pigs weighing 20 kg initially were given a ration based on maize which is normally used for performance testing in the Netherlands or a least-cost ration with more byproducts, twice daily at 50, once daily at 100 or once every 2 days at 200 g/kg0.75. Metabolism trials were made when the pigs reached 35, 65 and 85 kg. Blood was sampled at intervals just before feeding. Growth rate and feed efficiency were greater in pigs fed once daily than in those fed twice daily by 4 and 3% respectively. Nonesterified fatty acids in blood showed that pigs need be fed only once daily. Performance of pigs fed every 2 days was poor. The least-cost ration caused a decrease in growth rate and feed efficiency but produced thinner backfat and a greater percentage of meat. (Abstract retrieved from CAB Abstracts by CABI’s permission)
