Abstract

Se realizó una validación preliminar de un panel de marcadores SNP seleccionados de genes candidatos, relacionados al eje endócrino que regulan la hormona de crecimiento GH/IGF1, y a la formación y desaturación de ácidos grasos SCD/SREBP1, con características de composición de canal, calidad de carne y perfil de ácidos grasos de la grasa intramuscular en novillos Hereford sometidos a diferentes tratamientos de alimentación durante la etapa de recría y engorde intensivo. Se ajustaron las variables por el efecto de los 8 tratamientos nutricionales y se calcularon los valores residuales para los análisis de asociación con los marcadores SNP. Se determinó un total de 11 696 genotipos de 237 novillos utilizando un panel de 58 tag-SNP en los genes GHR, IGF1, IGFBP6, PMCH, SOCS2, STAT6, SCD1, SCD5, SREBP1, SCAP, INSIG1, INSIG2, MBTPS1, MBTPS2 y SRPR, de los cuales se encontraron 11 SNP polimórficos que estuvieron asociados signifi-cativamente: GHR_ rs41639262 sobre EGSu y MARBL; IGF1_ rs136251088 sobre PCC, PCE y PISTOLA; PMCH_ rs135033882 sobre OMEGA36; SOCS2_ ss252841026 sobre Terneza2d; STAT6_ rs109171041 sobre Terneza2d; STAT6_ rs110097583 sobre Terneza2d; INSIG1_ rs109314460 sobre Terneza21d; INSIG1_ ss252452220 sobre OMEGA36; SCD5_ ss252452202 sobre PUFA y Terneza2d; SCD5_ rs43687655 sobre EGSu y OMEGA36; SRPR_ rs42178091 sobre GRASAINTR, SFA, MUFA, PCC, PCE y PISTOLA. Estudios adicionales podrían confirmar estos efectos, posibilitando mejorar la calidad de la canal y de la carne, de animales sometidos a diferentes tratamientos de alimentación a través de la selección.

Abstract

The phenotype-genotype associations of a panel of SNP markers selected from candidate genes related to the growth hormone GH/ IGF1endocrine axis and the fatty acid synthesis and desaturation SCD/SREBP1 pathways, were examined. Phenotypes of interest were carcass composition, meat quality and fatty acid profiles of intramuscular fat in Hereford steers under different feeding treatments during the growth and finishing stages. Variables were adjusted for the effect of eight nutritional treatments and residual values were used in the association analysis with the SNP markers. A total of 11 696 genotypes of 237 steers were determined using a panel of 58 tag- SNP in the GHR, IGF1, IGFBP6, PMCH, SOCS2, STAT6, SCD1, SCD5, SREBP1, SCAP, INSIG1, INSIG2, MBTPS1, MBTPS2 and SRPR genes. A total of 11 polymorphic SNP were significantly associated with traits of interest: GHR_ rs41639262 on EGSu and MARBL; IGF1_ rs136251088 on PCC, PCE and PISTOLA; PMCH_ rs135033882 on OMEGA36; SOCS2_ ss252841026 on Terneza2d; STAT6_ rs109171041 on Terneza2d; STAT6_ rs110097583 on Terneza2d; INSIG1_ rs109314460 on Terneza21d; INSIG1_ ss252452220 on OMEGA36; SCD5_ ss252452202 on PUFA and Terneza2d; SCD5_ rs43687655 on EGSu and OMEGA36; SRPR_ rs42178091 on GRASAINTR, SFA, MUFA, PCC, PCE and PISTOLA. Additional studies could validate the marker-trait association effects that would make it possible to use these genetic markers to improve carcass and meat quality of animals under different feeding regimes.
