[The prececal digestibility of corn, sunflower, cottonseed, linseed and soybean extract meal in swine with ileocecal anastomoses].
Five pigs were each surgically prepared with end-to-side (E.t.S.) and end-to-end (E.t.E.) ileorectal anastomoses (IRA). The ileo-caecal valve was preserved in both modifications. The animals were fed diets with maize or solvent extracted oil seed meals from sunflower, cottonseed, linseed or soybean and maize in combination with one of these oil seed meals. The aim of the experiment was to estimate the influence of both IRA-techniques on the precaecal nutrient digestibility and amino acid (AA) absorption. The crude carbohydrate digestibility in two of the five single protein diets and in three of the four blends were significantly higher in the E.t.S.--than in the E.t.E.--IRA group. There were no significant differences between the two IRA-modifications in crude protein (CP) and crude fat digestibility. No differences were observed in AA absorption for the single components maize, sunflower- and cottonseed meal. The absorption values of isoleucine, leucine and valine from linseed meal were significantly more than 5%-units higher in the E.t.S.-group than in E.t.E.-animals. There were similar results in soybean meal for four essential AA but with differences below 5%-units. Accordingly the two IRA-modifications did not influence the AA absorption to a practically important extent.
