Single crossing experiments with romanovs in hungarian fine wool merino flocks ii. meat and wool production quality of wool


, : Single crossing experiments with romanovs in hungarian fine wool merino flocks ii. meat and wool production quality of wool. Allattenyesztes es Takarmanyozas 36(2): 165-174

The authors initiated single crossings with Romanovs in three flocks of Hungarian Fine Wool Merinos. The investigations indicated no differences between F1 and pure bred lambs of Merino in respect of weight gain. FCR, carcass weight and lean production. All connective tissue content and total pigment content of samples taken from the m. longissimus dorsi of F1 lambs were higher than that of Merinos examined in earlier experimentes (Veress and Kakukk, 1972, Veress et al., 1984). The results of other characteristics (tenderness and cooking loss) were also favourable. Crude weight of the wool was decreased by 20% in the F1 population. However, the relative weight of the wool (crude weight: body weight) decreased only by 11%. Due to the 10- 20% more favourable fleece length the average income on wool was not lagged behind the Merinos. Quality of the pelage of R1 lambs was by 16% inferior to Merinos. In the authors' opinion advantages of the single crossing with Romanovs compensate the accompanying disadvantages.
