Backfat thickness

Candidate genes for carcass traits in a tropical-adapted Brazilian composite beef breed

G. Veneroni-Gouveia, Tizioto, P. C., Meirelles, S. L. C., Santiago, A. C., Alencar, M. M., and Regitano, L. C. A., “Candidate genes for carcass traits in a tropical-adapted Brazilian composite beef breed”, vol. 14, pp. 16667-16674, 2015.

Backfat thickness (BFT) and ribeye area (REA) are important production traits but, because they are measured late in the animal’s life, they have not been efficiently included in breeding programs. The aim of this study was to evaluate whether single nucleotide polymorphisms (SNPs) mapped to the leptin, PPARGC1A, PSMC1, CRH, and FABP4 genes, which influence BFT and REA in Canchim cattle, a composite beef breed (5/8 Charolais + 3/8 Zebu). BFT and REA phenotypic records were obtained by ultrasound measurements from 18-month-old animals.

W., “Distribution of H-FABP and ACSL4 gene polymorphisms and their associations with intramuscular fat content and backfat thickness in different pig populations”, vol. 13, pp. 6759-6772, 2014.

Here, we analyzed the distribution of H-FABP/(HinfI, MspI, and HaeIII) and ACSL4/RsaI polymorphisms, and the associations of these 4 polymorphic loci with intramuscular fat (IMF) content and backfat thickness (BFT) in Yanan, Jinhua, Duroc, Landrace, Yorkshire, and Duroc x (Landrace x Yorkshire) (DLY) pigs. H-FABP/HinfI polymorphisms were present in all the 6 populations.
