Abstract:
The aim of this study was to compare the Crude Protein (CP) and amino acid contents of some protein sources used in livestock production in Turkey. The protein sources had a significant (p<0.001) effect on the CP and amino acid contents. Generally protein sources from legume grains had significantly (p<0.001) lower essential amino acid content than those of Soybean Meal (SBM) and Fishmeal (FM). Protein sources from legume grains are very poor in especially methionine and lysine when compared with those of fish meal. On the other hand, protein sources from legume grains had only significantly (p<0.001) lower non-essential amino acid content than that of FM. As a conclusion, grains from Lathyrus sativus, Vicia peregrina, Pisum elatius and Vicia narbonensis have potential as an alternative protein source, however, grains from Lathyrus sativus, Vicia peregrina, Pisum elatius and Vicia narbonensis should be supplemented with methionine and lysine amino acids to obtain the optimum performance from livestock when these protein sources are used as an alternative protein source in livestock diets.
