|
A total of 360 Berkshire(hog) weighing 25kg were fed experimental diets containing either dehulled soybean meal(DSBM) or non-dehulled soybean meal(NDSBM) as a major protein source until they reach 80kg. The pigs were then fed the finisher diets either high(3,265 kcal/kg) or low(2,940 kcal/kg) in ME to evaluate the effects of dietary energy level for finisher phase on the growth performances, carcass and meat quality parameter.
In growth performance, daily weight gain(kg/day) was higher(P<0.05) in T1 than in other groups. Feed conversion(feed/gain) was lower(P<0.05) in other groups. In carcass parameter, carcass percentage was higher(P<0.05) in T2 than in T1 and T4. Backfat thickness was lower(P<0.05) in T2 than in T1 and T3. The ratio of up B grade in carcass grade tender to be higher in T2 than in other groups. In meat quality, chemical composition was similar between groups. WHC was slighter higher in T1 than in other groups. Shear force was tender to be higher in T1 than in other groups. Hunter L and a in meat color were tender to be higher in T2 than in other groups. Hunter L in backfat color was thender to be higher in T1 than in other groups.
The results indicate that growth performance and carcass parameter of Berkshire were improved by the dehulled soybean meal as comparison with non-dehulled soybean meal during growing and finishing periods.
