The objective of this work was to determine nutritive parameters of rye, variety Fernando (grown in three different localities in Slovakia) and triticale (variety Kendo). Results of chemical analyses show significant differences (P<0.05) in content of nutrients among the studied rye samples. Protoplasmic proteins in rye grain reached up to 40% proportion out of the total amount of proteins and higher concentration of lysine. Effective degradability of organic matter varied from 74.5% to 85.7% and crude protein was degraded in rumen to 80% on average. Intestinal digestibility reached the value 67.91%. We tested the suitability of rye and triticale for nutrition of monogastric animals on broiler rabbits. Complete feed mixtures with 22.5% portion of these cereals were tested. Higher content of crude protein, fibre, lower content of fat and nitrogen-free extract in triticale increased the value of digestible and metabolizable energy in feed mixture. We found significant differences in digestibility of dry matter, crude protein, fat, organic matter, neutral detergent fibre (P<0.05), and in acid-detergent fibre (P<0.01) among the studied feed mixtures. We can summarize that rye and triticale represent cereals with higher portion of good quality proteins, high energy and nutritional value, and they can be incorporated into feed mixtures for ruminants and broiler rabbits (during the fattening phase) as a component of good quality. Nutrition-physiological specifics must be respected at feeding higher doses to individual animal species and categories.
