Evaluation of CM (Cell Mass from Lysine Fermentation) as on Alternative Protein Source in Broiler Diets

Abstract

【The experiment was conducted to evaluate CM (Cell Mass from Lysine Fermentation), which is used to produce synthetic lysine in industry, as an alternative protein source in broiler diets. Three different production conditions were employed to produce CMs (CM I, II, III). Treatments were control, CM I -1 (1 % of CM in the diet), CM I -3 (3% of CM in the diet), CM I -5 (5% of CM in the diet), CM II (3% of CM in the diet), and CM III (3% of CM in the diet). It was found that CM products were all high in crude protein content and especially high in lysine and methionine contents, while very low in minerals. For the starter period, all CM groups showed better weight gain, chicks fed CM I -1 diets were especially high in weight gain (p】
