Abstract
The production of crossbreeds between MD*GFM and GFM *MD had a very low efficiency. Even if the crosses between MD*GFM were very interesting in producing high quality carcasses, natural mating cannot be economically employed. The differences in anatomy and behaviour in fact cause a very low EF which must be increased by the imprinting in male 1 day MD and in GFM females or by the use of A.I.File in questo prodotto:
