Summary

Die Gehalte an Rohnährstoffen und vor allem an limitierenden Aminosäuren von ökologisch erzeugten Futtererbsen und Ackerbohnen sind vor dem Hintergrund der 100 %-Biofütterung von Interesse. Um den Einfluss von Sorte und Umweltfaktoren auf die Rohnährstoff-, Lysin-, Cystein- und Methioningehalte zu untersuchen, wurden in drei Jahren Proben aus Sortenversuchen in Deutschland genommen und mittels NIRS analysiert. Im Mittel enthielten Futtererbsen 21,9 g und Ackerbohnen 29,6 g Rohprotein in 100 g Trockensubstanz. Das Rohprotein von Futtererbsen und Ackerbohnen enthielt je 100 g im Mittel 8,0 g Lysin, 1,0 g Methionin und 1,4 g Cystein bzw. 6,4 g Lysin, 0,7 g Methionin und 1,1 g Cystein. Der Faktor Sorte beeinflusste die Rohprotein- und Rohfettgehalte von Futtererbsen und deren Ernteerträge sowie alle Inhaltsstoffe von Ackerbohnen signifikant. Umweltbedingte Faktoren und Interaktionen zwischen den Faktoren hatten ebenfalls Effekte auf die Zusammensetzung beider Kulturarten. Der Rohproteingehalt war in Ackerbohnen signifikant negativ mit dem Stärke-(r = -0,69), Zucker- (r = -0,47), Lysin- (r = -0,76) und Methioningehalt (r = -0,51) und in Futtererbsen mit dem Stärke- (r = -0,79), Zucker- (r = -0,55), Lysin- (r = -0,78), Methionin-(r = -0,61) und Cysteingehalt (r = -0,55) korreliert (p < 0,01). Die Schwankungen der Inhaltsstoffgehalte sind oftmals ungerichtet und somit nicht vorhersagbar, sodass eine laboranalytische Untersuchung der Futtermittel vor jeder Rationsberechnung empfohlen wird.

Summary translation

The composition of organically produced field peas and field beans as a source of valuable protein is of special interest for the planned 100 % organic feeding regulations in organic farming. For this reason, the influence of environment and variety on the contents of crude nutrients and the amino acids lysine, methionine, and cysteine were examined over three years. Laboratory analyses were conducted using NIRS.
Peas contained on average 21.9 % crude protein in the dry
matter with 8.0 % lysine, 1.0 % methionine, and 1.4 % cysteine. In field beans 29.6 % crude protein in the dry matter with 6.4 % lysine, 0.7 % methionine, and 1.1 % cysteine were found. Significant differences between varieties were found for crude protein and ether extract in field peas, as well as for all components in field beans. Environmental factors and interactions also had influences on the composition of both legume species. Furthermore, significantly negative correlations were found between the content of crude protein and starch (r = -0.69), sugar (r = -0.47), lysine (r = 0.76), and methionine (r = -0.51) in field beans, as well as of crude protein and starch (r = -0.79), sugar (r = -0.55), lysine (r = -0.78), methionine (r = -0.61), and cysteine (r = -0.55) in field peas. The shifts in composition were often undirected and for that reason not predictable. Hence, it is recommended to analyze every batch before formulating a diet.
