摘要:
Effects of dried distillers grains with solubles (DDGS) feeding strategies (a corn-soybean meal (CS) fed continously; CS + 40% DDGS fed continously; CS + 40, 30, 20, or 10% DDGS in 4 phases, respectively; or CS + 40% DDGS in phases 1 to 3 and CS in phase 4 before slaughter) on belly and pork fat quality of immunologically castrated (n = 192) pigs were evaluated. All pigs received the first Improvest dose at 11 week of age, and the second dose at 9, 7, or 5 week before slaughter at 24 week of age. Increasing the time interval of the second Improvest dose before slaughter reduced W in all fat depots and increased belly thickness. Gradually decreasing dietary DDGS and DDGS withdrawal feeding strategies reduced IV in all fat depots. Calculated IV were greater using the Meadus et al. (2010) equation compared with using the AOCS (1998) equation because it includes more long-chain unsaturated fatty acids.
