J. H. KimCollege of Agriculture and Life Science, Gyeongsang National UniversityABSTRACTThis study was carried out investigate the effect of replacing soybean meal with feather meal or Bacillussp. inoculated feather meal in finisher pig diets on the performances, and amino acid composition and carcasscharacteristics of pork. One hundred fifty pigs were randomly allotted to five dietary treatments ( control,①basal diet; BSM (② bacillus sp. inoculated soybean meal) 10, 10% of soybean meal was replaced withbacillus sp. inoculated feather meal; BSM 20, 20% of soybean meal was r③ eplaced with bacillus sp. in-oculated feather meal; CSM (conventional soybean meal) 10,④ 10% of soybean meal was replaced with con -ventional feather meal and CSM 20, 20% of soybean meal was rep⑤ laced with conventional feather meal)in a 70-days feeding trial. In overall period, body weight gain of BSM 20 (0.95kg) was higher (P<0.05) thanthose of CSM 10 (0.80kg) and CSM 20 (0.81kg), respectively. And feed conversion of BSM 20 (2.94) waslower (P<0.05) than that for other treatments (3.06~3.41). Carcass weight of BSM 10 (81.84kg) and BSM 20(83.77kg) were greater (P<0.05) than those of CSM 10 (74.75kg) and CSM 20 (76.07kg), respectively.Proportion of grade A carcass in BSM 20 (35.03%) was higher compared to the control treatment (32.78%).CIE L* of meat color was lowest in the BSM 10 (45.56), and hightest (P<0.05) in the CSM 20 (59.96). Inaddition CIE a* of meat color of control (9.35) highest (P<0.05) than those of BSM 10 and BSM 20 were7.56 and 7.42, respectively.(Key words : Bacillus sp. inoculated feather meal, Soybean meal, Body weight gain, Backfat thickness, Aminoacid)
