Causas del color amarillo de la grasa de canales de bovinos finalizados en pastoreo

Abstract

Most beef cattle are finished on pasture in Mexico. Adipose tissue of these animals may show some degree of yellow pigmentation, and because of the downgrading or even rejection of the resulting carcasses; economic losses are caused to producers. Yellowness of fat is due to carotenoids present in the diet. In this paper, the metabolism of these compounds at digestive-and tisular levels is studied. Although some practical solutions are currently available, they are not economically feasible, thus the need to know more about the causes of the deposition of the pigment, to then, look for better solutions to solve this problem.
