“…Failures in the chemical immobilization of wild boar and related species were never described, but the recourse to twofold drug injections (Sweitzer et al 1997a) or capture mortality were often reported (Zurowski and Sakowicz 1965;Henry and Matschke 1968;Matschke and Henry 1969;Wood et al 1977;Gallagher et al 1985;Fournier et al 1995;Gabor et al 1997;Sutherland-Smith et al 2004). The main used drugs in wild pigs and peccaries are (a) the dissociative anesthetics alone, such as ketamine (Lochmiller et al 1984;Gallagher et al 1985;Hellgren et al 1985), (b) the mixture of tiletamine/zolazepam (Fournier et al 1995), and (c) the combination of dissociative drugs with alpha2-adrenergic agonists, such as xylazine (Baber and Coblentz 1982;Allen 1992;Gabor et al 1997;Isle and Hellgren 1995;Sweitzer et al 1997a;Selmi et al 2003) and medetomidine (Tast et al 2000;Sutherland-Smith et al 2004).…”

During a 2-year study on wild boar ecology in a semiagricultural area of Northern Apennines (central Italy), 47 animals were caught with traps and subsequently immobilized with chemical restrain based on a 1:1 mixture of xylazine and tiletamine/zolazepam (1 ml contains: 50 mg of xylazine, 25 mg of tiletamine, and 25 mg of zolazepam). Effective chemical immobilization was observed in 55% of the caught wild boars, and a high capture mortality rate occurred (in 10.6% of wild boars). A posteriori analysis, by means of a logistic regression model, was performed to assess potential factors associated with wild boar chemical immobilization failure. Underdosage and increase in the number of animals caught together significantly increase the wild boar chemical restrain failure, while the capture mortality appears to be positively related to the sole trap size alone. The stress developed during the capture plays a relevant role influencing the outcomes of the anesthesia. Thus, the use of alternative handling or catching procedures with the aim to reduce stress in captured animals could maximize the safety and the efficiency of the wild boar chemical immobilization.
