|The Mangalica pig is a genetic model of excessive adiposity; therefore, this
European heritage breed may serve as an applied model to improve pork quality in
modern commercial lean breeds and as a biomedical model to study obesity-related
disease in humans. First growth performance and phenotypic differences were compared
between Mangalica breeds and the Yorkshire. Red Mangalica pigs exhibited the most
intramuscular fat; moreover, the York x Red Mangalica progeny displayed significantly
increased marbling score and lower cook loss compared to the purebred Yorkshire,
suggesting Mangalica pigs exhibit superior meat quality and Red Mangalica could serve
as a model for studying marbling. Since Mangalica pigs displayed an obese phenotype
that was driven by excessive voluntary energy intake, the second study aimed to establish
the Mangalica pig as a model for obesity-induced metabolic syndrome. Mangalica pigs
spontaneously developed risk factors associated with metabolic syndrome: obesity,
hyperglycemia, hyperinsulinemia, dyslipidemia, and low-grade chronic inflammation.
Together, these data suggest the Mangalica pig represents a model that enhances
biomedical and meat science research.
