A feeding trial with broilers was conducted to evaluate the effects of amino acids (lysine and methionine) supplementation of diets low in protein content on the voluntary intake, feed conversion efficiency, broiler performance, and cost and return of broiler production. Results showed cumulative voluntary feed intake was not significantly affected by lowering the protein content of the diet. Cumulative weight gain of broilers was lower with diet when supplemented iwht lysine and methionine to meet requirements. Birds fed with diets low in protein has less efficient feed converstion, but became comparable with those receiveing diets high in protein when supplemented with amino acids. Feed cost per kilogram broiler produced was not significantly affected by diets used in the study, although the low-protien diet with amino acid supplement had the lowest values. In terms of return above feed and chick cost, broilers fed with high-protein diet had the greatest value, but not significantly different from birds fed with low-protien diet with amino acid supplementation which gave about P10 per bird higher returns than those fed low-protein diet without amino acid supplementation.

Food Conversion Efficiency

Reducing the protein content of commercial diets in Europe would reduce environmental nitrogen pollution. It has been demonstrated that this could be achieved by employing crystalline amino acid supplementation (e.g. Chavel and Granier, 1994; Fuller et al, 1979a, b). Accurate information on the true ileal digestible amino acid requirements of the modern lean genotype pig is necessary in order to ensure optimal production at low protein intakes. The objective of this study was to identify the optimum ileal digestible methionine:lysine (met:lys) ratio to achieve maximal growth and food conversion efficiency of the lean genotype pig given low protein diets.
