“…Bandrick et al (2011) had demonstrated that transfer of Mycoplasma hyopneumoniae-specific CMI to piglets occurs only when piglets were maintained with their biological dams for at least twelve hours after parturition (Bandrick et al, 2011). To conclude, maternal antigen-specific leukocytes, delivered to piglets via colostrum, may constitute an extra line of active defense against infection for neonatal piglets (Goubier et al, 2009).…”

“…Moreover, Nechvatalova et al (2011) demonstrated that these cells possess functional abilities (they can become activated) and display an antigen-specific activity in organs (Nechvatalova et al, 2011). Goubier et al (2009) detected antigen-specific lymphocytes that were able to produce IFNγ and TNFα after in vitro stimulation with circoviral antigens vaccinated against PCV2 sow colostrum (Goubier et al, 2009). Bandrick et al (2008) demonstrated that lymphocytes obtained by piglets from vaccinated sow colostrum can proliferate and participate in functional response to Mycoplasma hyopneumoniae (Bandrick et al, 2008).…”

The immune system of neonate piglets differs from adult pigs in structure and competence. Although piglets are born immunocompetent, they are genuinely immunologically defenceless. To survive in the environment, piglets need passive protection provided by sow’s colostrum and milk when constantly exposed to numerous pathogens. Early assessment of piglets’ immune status may enable rapid intervention in case of detection of any deficiencies or disorders. Moreover, awareness of the piglets’ immunocompetence and the level of maternally-derived antibodies (MDA) may allow the creation of a proper vaccine schedule. Hence, extending knowledge of prenatal ontogeny of the porcine immune system, the immune status of neonate piglets’ and the immunological components of porcine colostrum is crucial. Since animal welfare has become a more critical element of animal production, new, non-invasive sampling methodologies are highly desirable for the evaluation of piglets’ immune status.
