INFLUENCE OF THE DIFFERENT PROTEIN LEVELS ON LAMB FATTENING

Nakon odbića u starosti od 2 do 2,5 mjeseca 51 janje pasmine würtemberg podijeljeno je u tri grupe. Kontrolna grupa hranjena je standardnom smjesom s 14% sirovih proteina, a dvije pokusne grupe s 18% sirovih proteina u smjesi. Viša razina proteina rezultirala je povećanim dnevnim prirastom - kontrola 261 g, pokusne grupe 321 i 333 g, te smanjenim utroškom energije za 30% i probavljivih proteina za 13% za jedinicu prirasta u odnosu na kontrolnu grupu.The total of 51 würtemberg breed lambs weaned at the age of 2-2.5 months have been classified into three groups. The control group was fed on 14% of crude protein in a standard food mixture and the two experimental groups on 18% of crude protein. The higher level of proteins resulted in 261 g daily gain in the control group and 321 and 333 g in the experimental groups, and in 30% decrease of energy consumption and 13% digestible proteins per unit gain in the experimental groups when compared to the control group
