Aunque las características productivas son aceptables, la calidad organoléptica de la carne se considera deficiente. Además del ambiente, este hecho se relaciona con la genética de los animales. De manera puntual, se sabe que algunas variantes alélicas de los genes CAPN1, CAST y LEP, relacionadas con carnes de mejor calidad, se encuentran en frecuencias muy bajas en esta raza. El objetivo de este estudio consiste en evaluar el efecto que tiene el sistema de producción sobre la asociación de los SNP CAPN316, CAPN4751, CAST282, CAST2959, E2FB y E2JW con las características de la canal y de la calidad de la carne de los bovinos brahman. Para ello, se evaluaron 410 bovinos macho de esta raza que provenían de cuatro ganaderías con modelos de pastoreo extensivo rotacional y con diferentes sistemas de producción, dos de ciclo completo y dos de ceba. En cada animal se genotipificaron los SNP CAPN316, CAPN4751, CAST282, CAST2959, E2FB y E2JW a partir de las pruebas PCR-HRM y PCR-RFLP. Asimismo, se evaluaron las características de la canal, las características nutricionales de la carne y sus atributos organolépticos durante los días 1, 7 y 14 de la maduración. Se confirmó la baja frecuencia de los alelos que favorecen las características organolépticas de la carne y se verificó la asociación de estos alelos con la producción de carne más tierna y jugosa. Sin embargo, está asociación está sujeta a los efectos del ambiente en el que se desarrollan los animales. Los animales provenientes del sistema de producción dedicado a la ceba presentaron carnes de mejor calidad. En contraste, en el sistema de ciclo completo se obtuvieron las mejores características de la canal. 8Tomado de la fuente)Beef livestock in Colombia is mainly based on Bos indicus animals of the brahman breed, adapted to the difficult conditions of the low tropics, characterized by a poor nutritional supply. Although the production characteristics are acceptable, the organoleptic quality of the meat is considered deficient. In addition to the environment, this is related to the genetics of animals, in a specific way, it is known that some allelic variants of the genes CAPN1, CAST and LEP related to meat of better quality and are in very low frequencies in this breed. In order to assess the effect of the production system on the association of CAPN316, CAPN4751, CAST282, CAST2959, E2FB and E2JW SNP with carcass traits and beef quality of animals of the Brahman cattle, 410 males of this breed from four farms with extensive rotational grazing models in two different production systems, two full-cycle and two fattening systems were evaluated. In each animal the SNP CAPN316, CAPN4751, CAST282, CAST2959, E2FB and E2JW were genotyped using PCR-HRM and PCR-RFLP, carcass traits, beef nutritional characteristics and their organoleptic attributes were evaluated during 1, 7 and 14 aging days. The low frequency of alleles associated with organoleptic characteristics of meat was confirmed, in addition the association of these alleles with the production of more tender and juicy meat was verified, however this association is subject to the effects of the environment in which the animals develop. The animals coming from the production system dedicated to the fattening presented meats of better quality, in contrast, in the complete cycle system where the best characteristics of the carcass were obtained.
