The effects of low- , medium- , and high-oil distillers dried grains with solubles on growth performance , nutrient digestibility , and fat quality in finishing pigs . A total of 1,480 pigs were used in 3 experiments to determine the effects of corn distillers dried grains with solubles ( DDGS ) varying in oil content on growth performance , carcass traits , and nutrient digestibility in finishing pigs . In Exp . 1 , 1,198 pigs ( PIC Line 337 × 1050 ; initially 46.1 kg ) were allotted to a corn-soybean meal-based diet or diets with 20 or 40 % of a 5.4 % oil DDGS ( 29.5 % CP , 8.9 % ADF , and 21.8 % NDF ; as-fed basis ) or a 9.6 % oil DDGS ( 29.6 % CP , 15.3 % ADF , and 28.6 % NDF ; as-fed basis ) . From d 0 to 82 , ADG was unaffected by DDGS source or level . However , increasing 5.4 % oil DDGS decreased ( linear , P < 0.01 ) G : F , whereas G : F did not change among pigs fed 9.6 % oil DDGS ( DDGS source × level interaction ; P < 0.01 ) . Regardless of DDGS source , carcass yield and HCW decreased ( linear , P < 0.04 ) with increasing DDGS . Increasing DDGS increased jowl iodine value ( IV ) , but the magnitude was greater in pigs fed the 9.6 % oil DDGS compared with those fed 5.4 % oil DDGS ( DDGS source × level interaction ; P < 0.01 ) . In Exp . 2 , 270 pigs ( PIC Line 327 × 1050 ; initially 46.5 kg ) were allotted a corn-soybean meal-based diet or diets with 20 or 40 % of a 9.4 % oil DDGS ( 29.4 % CP , 19.6 % ADF , and 34.5 % NDF ; as-fed basis ) or a 12.1 % oil DDGS ( 28.5 % CP , 17.6 % ADF , and 31.4 % NDF ; as-fed basis ) . From d 0 to 75 , ADG increased and then decreased for pigs fed 9.4 % oil DDGS but was unchanged for pigs fed 12.1 % oil DDGS ( quadratic interaction , P < 0.02 ) . Increasing DDGS increased ( linear , P < 0.01 ) jowl IV and tended ( linear , P < 0.07 ) to increase G : F. Regardless of source , HCW and carcass yield decreased ( linear , P < 0.05 ) as DDGS increased . In Exp . 3 , nutrient digestibility of the 4 DDGS sources was determined using pigs fed either a corn-based basal diet ( 96.6 % corn and 3.4 % vitamins and minerals ) or a DDGS diet with 50 % basal diet and 50 % DDGS . On an as-fed basis , corn contained 3,871 and 3,515 kcal/kg GE and DE , respectively . The 5.4 , 9.6 , 9.4 , and 12.1 % oil DDGS contained 4,347 , 4,648 , 4,723 , and 4,904 kcal/kg ( as-fed basis ) GE and 3,417 , 3,690 , 3,838 , and 3,734 kcal/kg DE , respectively ( as-fed basis ) . Stepwise regression indicated that the oil ( ether extract ) content was the only significant variable to explain differences in energy content . The equations generated to predict DE and NE as a function of oil content on an as-fed basis were DE ( kcal/kg ) = 62.347 × ether extract ( % ) + 3,058.13 ( n = 5 , adjusted R ( 2 ) = 0.41 ) and NE ( kcal/kg ) = 115.011 × ether extract ( % ) + 1,501.01 ( n = 5 , adjusted R ( 2 ) = 0.86 ) .
