*PDIF - protein digested in the small intestine
PDIN - protein digested in the small intestine supplied by rumen-undegraded dietary protein plus protein digested in
the small intestine supplied by microbial protein from rumen-degraded protein
PDIE - protein digested in the small intestine supplied by rumen-undegraded dietary protein plus protein digested in
the small intestine supplied by microbial protein from rumen-fermented organic matter
UFL - feed unit for lactation
UFV - feed unit for maintenance and meat production

+50%legumes) [own study]
crude protein concentartion was determined in wheat and vetch intercrop grain yield. The
same relationships have been found in the studies on mixtures of wheat and spring barley with
peas. In addition, it has been shown that these mixtures contained more methionine, and barley
also contained more threonine than cereals grown in sole crops [67].

The nutritional value of seeds and grains of legume-cereal mixtures is also analyzed by testing
the nutritional value of the protein expressed by the ratio of essential egzogenic amino acids-
