Projekat:
Primena novih biotehnoloških rešenja gajenja goveda, ovaca i koza u cilju dobijanja biološki vredne i zdravstveno bezbedne hrane (MPNTR - 31053)

Ključne reči: lamb; protein source; wool; diameter; height length
Sažetak
Eksperimentom je obuhvaćeno 30 jagnjadi-meleza F1 generacije pirotska pramenka (50%) x virtemberg (50%) i 30 meleza F1 generacije: pirotska pramenka (12,5%) x virtemberg (37.5) x Il de frans (50%), odbijenih na 60 dana starosti, prosečne telesne mase 18,0 kg. Smeše su se razlikovale u izvoru proteina: I - suncokretova sačma, II - sojina sačme i III - riblje brašno. Udeo nesvarljivih proteina je 43: 51: 58%. Prosečan prečnik vlakana u jagnjadi na tretmanima I: II: III je bio 26.14: 24.96: 25.20 μm, a kod dvorasnih (PxW) i trorasnih meleza (PxWxIDF): 25.38 i 25.49 μm. Prosečna visina vune u jagnjadi na tretmanima I: II: III je bila: 2.97: 3.06: 3.17 cm, a kod dvorasnih (PxW) i trorasnih (PxWxIDF) meleza: 2.98: 3.15 cm. Prosečna dužina vlakana u jagnjad na proteinskim izvorima I:II:III je bila 4.62: 5.08: 5.11 cm, a kod dvorasnih (PxW) i trorasnih (PxWxIDF) meleza 4.77: 5.11 cm. Izvor proteina u smešama hrane, kao i genotip jagnjadi, značajno su uticali na kvalitet vune izražen kroz prečnika, visinu i dužinu vlakana.
