Hot on the heels of the UK’s call for “advances in nutrition and related sciences” to be put to work to improve the efficiency of animal production, comes a paper surveying the protein content and composition of “107 cultivars of important grain legume species”. The primary motivation seems to have been to improve feed quality for pigs, especially for the organic sector which is not supposed to feed supplementary amino acids to make up the shortfall. From the abstract, it seems that feed quality could indeed be enhanced by selecting specific varieties. And a more diverse diet, to supply the amino acids in which most pulses are low?
