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.

Balanced intraintestinal nutrition: comparison of absorption degree of selected fats and emulsions of fats.

The absorption of emulsion of soybean oil, soybean oil and molted butter was compared with that of the Intralipid preparation manufactured by Vitrum. The experiments were carried out on a dog and rats using the method of isolated intestinal fistulae. It was found that the emulsion of soybean oil prepared by the authors was absorbed in a degree similar to that of Intralipid fat emulsion and that it could be used as a component of a preparation intended for balanced non-residual intraintestinal nutrition.

Balanced intraintestinal nutrition: digestion, absorption and biological value of selected preparations of milk proteins.

The absorption of an enzymatic hydrolysate of whey proteins, hydrolysates of milk proteins and casein, 7% hydrolysate of bovine blood produced by Polfa under the trade name "Aminokwasy", and a standard mixture of amino acids from isolated small intestine loop of dogs and rats was compared. The composition of amino acids of the initial proteins and hydrolysates obtained from these proteins was determined. The biological value of selected proteins and hydrolysates was assessed determining the mean weight gain, nitrogen content of the body, urinary excretion of urea and creatinine, blood urea level and NPU.
