Abstract
Sixty-four gilts, average initial weight of about 120 kg, were used to evaluate the use of Distillers Dried Grains with Solubles (DDGS) as a replacement for soybean meal in a corn:soybean meal diet fed during gestation. Dietary levels of DDGS were 0, 17.7 and 44.2%, with all diets containing about .42% (calculated) lysine. Two gilts from each treatment were used in a nitrogen balance determination during the 84th through the 88th day of gestation. Average gestation gain, litter size and weight at birth were similar for all dietary treatments. During lactation all sows received a fortified 16% crude protein diet. Litter size and weight at weaning (28 days) and sow weight change were similar for all groups. Grams of nitrogen retained per day, 84th through the 88th day of gestation, did not differ significantly among diets. Percent of dietary nitrogen retained was lower (P<.05) from the 17.7 and 44.2% DDGS diets than from the control diet, which likely reflects the deamination of excess amino acids in the DDGS diets. These results show that DDGS can replace soybean meal on a lysine-equivalent basis as a source of supplemental amino acids in diets for gestating swine. Copyright © 1978.
