| الوصف: | The relations between the proportion of acid detergent insoluble nitrogen (ADIN, in g kg–1total N) on one hand and concentrations of crude protein and crude fibre on the other have been investigated. It was found that with increasing concentration of crude protein (CP) the proportion of ADIN in grassland forages decreased while with increasing concentration of crude fibre (CF) it increased. At given CP concentration the proportion of ADIN in legumes was higher than in grasses. Proportion of ADIN in hay from extensively managed grasslands was considerably higher than in hay from intensively managed grasslands. At given CP concentration there was a tendency of lower proportion of ADIN in first cut silages in comparison to silages which were made from consecutive cuts. Equations which enabled prediction of the proportions of ADIN in the samples of green forage, hay and silage on the basis of concentration of CP were calculated. It was established that they allowed rough estimates. For the present, accurate concentration of ADIN can be achieved only by the means of chemical analysis. ; Proučevali smo povezave med deležem v kislem detergentu netopnega dušika (KDNN, v g kg–1skupnega N) na eni strani ter vsebnostma surovih beljakovin (SB) in surove vlaknine (SVl) na drugi. Ugotovili smo, da se v krmi s travinja s povečevanjem vsebnosti SB delež KDNN zmanjšuje, medtem ko se s povečevanjem vsebnosti SVl povečuje. Pri dani vsebnosti surovih beljakovin je bil pri metuljnicah delež KDNN večji kot pri travah. Delež KDNN v senu z ekstenzivnih travnikov je bil večji kot pri senu z intenzivnih travnikov. Pri silažah prve košnje smo pri dani vsebnosti SB opazili tendenco manjšega deleža KDNN kot pri silažah iz naslednjih košenj. Izračunali smo enačbe, ki omogočajo napovedovanje deleža KDNN v vzorcih zelene krme, sena in silaž na podlagi vsebnosti SB, in ugotovili, da omogočajo grobo oceno. Zaenkrat lahko dobimo točno vsebnost KDNN le s kemijsko analizo. |
