Abstract:
1. In a series of five trials, conducted with broiler chicks during the starting period, two types of dietary single-cell protein were tested: Pruteen (PR), a protein concentrate produced from methanol-utilising bacteria, and a Lavera-type yeast (LA) utilising the normal paraffins of heavy gas oil. 2. The inclusion of 90 to 150 g PR or LA/kg diet depressed growth rate by 14 to 16% and 9 to 10%, respectively. This effect was slightly counteracted (about 6 percentage units) by the addition of L-arginine. 3. The growth depression can be explained completely in the case of PR or almost completely in that of LA on the basis of reduced food intake, without a decided effect on food utilisation. 4. The reduced consumption of PR-containing diets is not due to a petroleum-ether-soluble factor, nor to the high and low concentrations of sodium and potassium, respectively, in PR. 0007-1686/81/00150123$02.00. © 1981, Taylor & Francis Group, LLC.
