1. Three trials were carried out with male broilers during the 5- to 8-week period, for the evaluation of two types of single-cell protein (SCP) in practical-type broiler finisher diets. The SCP tested were: Pruteen, produced from methanol-utilising bacteria, and a Lavera-type yeast which utilises the normal paraffins of heavy gas oil. 2. The inclusion of 90 to 100 g of either type of SCP/kg of the diet caused a 2 to 3% reduction in weight gain, a 3 to 5% decrease in food consumption, and up to a 2% improvement in food utilisation. The reduced growth rate could be fully explained by the decrease in food intake, with essentially no effect on food : gain ratio. 3 In diets containing Pruteen, arginine was second limiting after the sulphur amino acids. 4 An odd-numbered fatty acid (17 carbons, unsaturation unknown) of Pruteen was not found in the carcass lipids of broilers fed on a diet containing 120 g Pruteen/kg. |
