Abstract
Aiming to create some Romanian breeds which are specialized for the meat production, well adapted to the environment conditions from Romania two populations of half-breeds were created: at ICDCOC Palas-Constanţa Suffolk x Merinos of Palas and Texel x Meat Breed Palas and at SCDCOC Reghin-Mureş German with Black Head x Ţigaie. The morph - productive parameters of the F1 half-breeds were: F1 Suffolk x Merinos of Palas half-bred rams reached an average living weight of 109.86 kg, having an average production of wool of 6.47 kg, with the length of the tufts of 7.71 cm and the finesse of the fibers of 23.71 microns; the rams of Merinos of Palas (the control lot) had the body weight of 89.5 kg, the quantity of wool being of 9.10 kg, with the length of the tufts of 10,33 cm and the finesse of 21.33 microns; the half-bred rams of Texel x Meat Breed of Palas reached an average living weight of 103.00 kg, having an average production of wool of 3.90 kg, with the length of the tufts of 8.80 cm and the finesse of the fibers of 23.00 microns; the rams from the Meat Breed of Palas (control lot) had the body weight of 95.23 kg, the wool quantity being of 3.88 kg, with the length of the tufts of 8.40 cm and the finesse of 22.23 microns; the half-bred rams of F1 German with Black Head x Ţigaie had, after hair-cutting, the body weight of 72.50 kg, the value being intermediary between the rams of German with Black Head breed which had 93.33 kg and the rams of Ţigaie with 68.57 kg; the quantity of physical wool was of 3.83 kg, at the F1 half-bred rams, comparatively to 4.43 kg at the rams of German with Black Head breed and 3.34 kg at the rams of Ţigaie breed.
