Lipid composition of muscle and fat tissues of duroc pigs (Sus scrofa domesticus Erxleben, 1777) - features and correlations

A key direction in animal genetics and animal breeding is currently the study of metabolic characteristics of animals in combination with their genotyping, which leads to the development of the new specific markers for prediction the individual phenotypic characteristics of animals based on correlation studies. This would further make possible to create new methods for animal phenotyping using lipid analysis techniques to assess the complex effect of environmental and genetic factors (D.P. Lo Fiego et al., 2002; D.P. Lo Fiego et al., 2005; R. Rossi et al., 2002). Data obtained as a result of the analysis of the genetic features of the animal and its metabolic characteristics make it possible to create predictive models for accurate phenotyping of animals and their offspring. In this work we have for the first time performed the comparative non-targeted mass-spectrometry study of the lipid composition of muscle and adipose tissue in Russian Duroc pigs using positive ion registration mode...
