Abstract

CASTILLO VARGAS, Julián Andrés. Metabolism and function of lipids in the adipose and liver tissues of production ruminants: a review. Ces. Med. Vet. Zootec. [online]. 2019, vol.14, n.2, pp.30-44. ISSN 1900-9607.  https://doi.org/10.21615/cesmvz.14.2.3.

The adipose and liver tissues influence the fatty acid metabolism, being largely responsible for regulating their biosynthesis, degradation and storage in body tissues, as well as for their secretion in milk and meat production from ruminants. Therefore, a better understanding of the functionality of fatty acid metabolism in these tissues and the factors that affect it, could provide the basis for the design of productive strategies in ruminants. Thus, the aim of this review is to present a general overview of the functionality and metabolism of fatty acids in the adipose and liver tissues in production ruminants. From the review, it could be established that fatty acids and triglycerides are the main lipid types in adipose and liver tissues. Adipose tissue is the main energy storage site for both ruminants and non-ruminants. Adipose tissue is metabolically associated with liver tissue through an equilibrium that regulates the processes of β-oxidation, de novo synthesis, and fatty acid transport at a tissue level. Finally, it was established that the fatty acids metabolism in adipose and liver tissue is affected by several factors, including nutrition and level of dietary restriction, genetics, physiological state, and environment, being nutrition the main factor.
