KCNJ11 gene expression is associated to feed consumption and growth traits in Nelore beef cattle

FABP1 and SLC2A5 expression levels affect feed efficiency-related traits

“…The following parameters were estimated: individual dry matter intake (DMI, kg/d), body weight (BW, kg), metabolic BW (MBW, kg), DMI as a percentage of BW (DMI%BW), average daily gain (ADG, kg/d), residual feed intake (RFI, kg/d), feed conversion ratio (FCR, kg/kg), feed efficiency (FE, kg/kg), Kleiber index (KI, ADG/MBW), and relative growth rate (RGR%/d) (Bergh et al, 1992;Diniz et al, 2018;de Oliveira et al, 2014).…”

“…These studies showed different quantitative trait loci (QTLs) and differentially expressed (DE) genes among breeds, and between efficient and inefficient animals. Although genomic regions and genes may not hold across studies, biological processes as lipid, protein, insulin, and carbohydrate metabolism involved with FE are in agreement among them (Diniz et al, 2018;Mukiibi et al, 2018;de Oliveira et al, 2018). Additionally, most of the genome-wide expression profiling studies employed case-control approaches, which does not consider the continuous variation of gene expression across the whole population once divergent groups are selected.…”
