“…This study evidences the presence of pet pigs stablished in the wild due to deliberate or accidental abandonment, resulting in establishments in new colonies(Delibes-Mateos & Delibes, 2013). The presence of pregnant females, piglets and hybrids in the study demonstrated the hybridization between miniature pigs and wild boars in Catalonia, since animals of different age, sex and species were found coexisting but not being castrated.TA B L E 2Note: A, forest; B, outdoor cement; C, outdoor enclosure.…”

“…This study included 211 miniature pigs of different ages and sexes from a North‐East region of Spain (Catalonia) during December 2018 to January 2020. Thirty animals out of two hundred and eleven were hybrids between miniature pig and wild boar according to morphological characteristics (Delibes–Mateos & Delibes, 2013 ). Hybrids may show characteristics of both animals as a more compact body and longer legs, longer hair or even absence thereof, long snout or also appearance of animals with flat snout (Figure 1 ).…”

“…Currently, the abandonment of miniature pigs and crossing breeds with wild boars can cause problems in public health since the animals inhabit in urban or semi‐urban areas where their control and eradication is difficult, thus requiring more strict regulations to control ownership to prevent uncontrolled breeding and infection among wild boars, semi‐wild pigs and farm pigs (Delibes–Mateos & Delibes, 2013 ; Royal Decree 1392/2012). Notifiable diseases in pigs in Spain include, among others brucellosis, African swine fever (ASF), classical swine fever (CSF) and Aujeszky's disease (AD).…”

Background: Miniature pigs have gained popularity as companion animals in the recent years in Spain. Due to the fact that their abandonment and crossing breeds with wild boars can cause severe problems, investigation about the health status is needed. Objectives:The aim of this study was to determine their health status according to the clinical findings during physical examination and the results of antibody serology tests against selected infectious diseases.Methods: Two-hundred and eleven miniature pigs (Sus scrofa) were included in the study. Their origin, age, sex, housing conditions and diet were recorded. Results:The housing of the animals ranged from wild animals to ones living in animal sanctuaries. The diet varied from a natural one in the wild to commercial and homemade food. Thirty animals out of two-hundred and eleven were hybrids between miniature pigs and wild boars according to morphological characteristics. Antibody serology techniques of Influenza A virus, Hepatitis E virus, brucellosis, tuberculosis, African swine fever, Classical swine fever and Aujeszky's disease was performed. The prevalence for Influenza A was 5.30%, for Hepatitis E was 5.35% and the rest tested negative. It is important to control and monitor these zoonotic infections to prevent Public Health problems. Conclusions:The results obtained from this investigation demonstrated that the animals' health status in this study is optimal and the diseases prevalence is similar or minor when compared to previous studies. This study confirms the hybridization of miniature pig and wild boar in Catalonia.

“…The adult animals possess a pot-belly shape with droopy back posture. Among different pig breeds, Vietnamese pot-bellied pigs (Sus scrofa) have pot-belly shape abdomen [2] . The male Zovawk animals are heavier till one year of age (30-35 Kg) and at around three years of age females (50-60 Kg) are usually heavier than the males (45-50 Kg) (Figure 1).…”

The Mizo local pigs (Zovawk) are small variety of pigs in which adult body weight ranges from 40-50 kg. It is a newly recognised pig breed of Mizoram by the ICAR-National Bureau of Animal Genetic Resources, Karnal (NBAGR). Scientific studies are scanty. Present study aimed to report the phenotypic characterisation of Zovawk. The whole body is covered by black hairs with a star forehead. The four limbs below the knee region are covered by white hairs. Zovawk pig attained puberty at 143.20±1.44 days in males and 120±1.18 days in females. Average litter size at birth and weaning were 7.5±0.01 and 6.17±0.007 respectively. Average litter weight (kg) at birth and weaning were 4.61±0.007 and 25.31±0.63 respectively. Average individual weight (kg) at birth and weaning were 0.61±0.016 and 4.41±0.16. Body weight (kg) at birth, weaning, five months, eight months and during first farrowing were found 0.61±0.016, 4.41±0.16, 12.65± 3.4, 23.79± 5.2 and 30.15± 2.6 respectively. The average age at first farrowing was 314.9±5.8 days.

“…In addition, we received many reports of pot-bellied pigs and in some cases, these animals had spent several seasons outside of captivity, suggesting that these abandoned pets are capable of surviving in the wild in Ontario. Pot-bellied pigs contribute to the wild pig population in other jurisdictions as well (e.g.,Caudell et al, 2013;Delibes-Mateos & Delibes, 2013).…”

Once an invasive species has been introduced and becomes established in a region, eradicating that species becomes increasingly expensive and, depending on the species, may be financially and logistically unfeasible (Parkes & Panetta, 2009;Vitousek et al., 1996). Successful control strategies for invasive species involve a combination of preventing the introduction of the invader, detecting early invaders, and rapidly removing those early invaders (Mehta et al., 2007). Preventing the introduction and subsequent establishment of an invasive species, while challenging (Mehta et al., 2007), is the most efficient method to prevent widespread invasion (Leung et al., 2002;Reaser et al., 2020).Identifying the potential pathways of invasion is thus a critical step for preventing new or continued invasions.Wild pigs (Sus scrofa) have successfully invaded every nonpolar continent worldwide (Barrios-Garcia & Ballari, 2012;
