Balanced intraintestinal nutrition. A preparation for intraintestinal no-residue nutrition.

The investigations were carried out on dogs and male Wistar rats using the method of isolated intestinal loops. The absorption of nitrogen from a preparation was studied. The protein component of the preparation was an enzymatic hydrolysate of whey proteins, milk proteins, casein and a 7% bovine blood hydrolysate manufactured by Polfa. Comparative investigations were carried out on the effect of the protein component on the absorption of fat from the tested preparation. No significant differences were found in nitrogen absorption from the hydrolysates of milk proteins administered in the form of a protein-fat-carbohydrate emulsion or in fat absorption depending on the protein component. On the basis of theoretical assumptions and experiments on laboratory animals the composition of a preparation for balanced no-residue intraintestinal nutrition was elaborated in which the protein component was a hydrolysate of whey proteins without lactose and the fat component was soybean oil.
