PERFORMANCE AND CARCASS CHARACTERISTICS OF FINISHING PIGS FED RAW OR EXTRUDED FULL-FAT SOYA BEANS RATIONS IN HUMID LOWLAND TROPICS

Abstract

Sixteen Landracex Large White crossbred pigs  averaging 56 kg body weight were used in a study to uvestigate the effects of feeding raw full-fat soyu bean (RSB) rations on the performance of pigs in humid lowland tropics. Raw full-lat soya bean was used to replace extruded full-fat soyabean at 33, 67 and 100% in finishing swine diets having 16% C.P. and 2800 kcal/kgME and fed ad lib. ADG was reduced by the addition of RSB to the diets (P>0.05). However, FE was improved (P>0.05) when 67 over (P>0.05) when 67 and 100% RSB were added to the diets. RSB significantly (P<0.05) affected backfat deposition and percent lean cut of the carcass. Other carcass traits were not affected.
