Abstract:
Growing chicks received diets containing 10% soybean oil and either raw or heated soybean meal during a 4 day period. 91YCl3 was added to serve as a nonabsorbable reference substance. At the end of the experimental feeding, the contents of five intestinal segments were assayed for lipids, bile acids and 91Y. More than 95% of the dietary triglycerides were broken down in the contents of the duodenum, the major products of hydrolysis being free fatty acids, accompanied by smaller amounts of di- and monoglycerides. Partial glycerides disappeared in the following segments, leaving essentially only free fatty acids in the lower small intestine. Raw soybean meal did not affect the pattern of triglyceride breakdown in the upper small intestine, nor did it inhibit lipase activity in the intestinal contents. As noted previously, raw soybean meal caused enhanced secretion of bile acids and total fatty acids in the duodenum, followed by reabsorption of the greater part of these compounds between the duodenum and upper jejunum. The results show that raw soybean meal does not interfere with fat digestion, and that the increased fecal excretion of fatty acids and bile acids is due to interference by the raw soybean meal with the absorption of these compounds in the lower jejunum and ileum. Possible mechanisms accounting for the block in absorption are discussed.
