Although sheep breeding in our country mainly had extensive character, there is still room for implementation of the new concept of expression of nutritional value of proteins, primarily in fattening of lambs. For the purpose of maximum use of the genetic potential of high-yielding meat/fattening sheep breeds, share of undegradable protein in diet must be taken into consideration, since high protein requirements of such animals cannot be satisfied by microbial protein synthesis from usual protein and energy sources. Therefore, in contemporary, science based systems for assessment of protein value of feeds, degradability of proteins from food in rumen plays major role. In absence of data in domestic literature related to undegradability of proteins in certain feeds, results obtained in this study should be perceived as direction for future norming of diets in fattening of lambs in the intensive rearing system.
