Addestramento alla raccolta del seme mediante vagina artificiale nell'ariete di razza massese

Adult Massese rams are generally ill-tempered subjects, hardingly conditionable to new sex drives. The A.A. relate about protocols adopted in accostuming Massese sires to semen collection by artificial vagina for I.A. service. Their experiences involved seven male lambs, breed, on pourpose, in single pens, and submitted to accurate profilactic and sanitary analysis. Special care has been applied in describing igienic and breeding management, shelters and collecting-room equipments, and animal’s sex drive requirements. The most tedious managerial problem arised from continuous horn-figthing against boxes. One, in seven subjects, died abruptly for unknown causes, while six resulted accostumed to artificial collecting method . Of these, two, from the same flock have been culled for sanitary reasons (serologic positivity to CAEV virus), while a third reported blindness after heavy knock out during an occasional and unexpected horn-figthing with another ram (cranic trauma with CNS lesions).
