“…). Vasectomy is another option, but vasectomized hobs remain aggressive and have a musky odour similar to that of intact hobs (Schoemaker ). In females, ovariohysterectomy is performed in the same manner as in cats.…”

“…). In these cases, a second dose suppressed oestrus for the rest of the breeding season (Schoemaker ; Prohaczik et al. ).…”

“…). Slight alopecia has been reported in ferrets after proligestone administration, and a prolonged pregnancy (gestation 51 days) has been reported in two ferrets having received proligestone when they were in oestrus and had been mated (Schoemaker ; Prohaczik et al. ).…”

“…The pre‐ovulatory LH surge can be mimicked by the administration of hCG (100 UI) or indirectly by stimulating endogenous LH release by the administration of GnRH (20 μ g) given intramuscularly 10 days after the onset of oestrus (Schoemaker ). These drugs stimulate ovulation 35 h after injection in 95% of the cases followed by anoestrus (pseudopregnancy) for a 40‐ to 60‐day period (Schoemaker ; Prohaczik et al. ).…”

“…). No side effects have been reported with hCG, but multiple injections of GnRH may sensitize the ferret to the drug, resulting in anaphylactic reactions shortly after administration (Schoemaker ).…”
