Brazilian Nellore cattle (Bos indicus) have been selected for growth traits for over more than four decades. In recent years, reproductive and meat quality traits have become more important because of increasing consumption, exports and consumer demand. The identification of genome regions altered by artificial selection can potentially permit a better understanding of the biology of specific phenotypes that are useful for the development of tools designed to increase selection efficiency. Therefore, the aims of this study were to detect evidence of recent selection signatures in Nellore cattle using extended haplotype homozygosity methodology and BovineHD marker genotypes (>777 000 single nucleotide polymorphisms) as well as to identify corresponding genes underlying these signals. Thirty-one significant regions (P < 0.0001) of possible recent selection signatures were detected, and 19 of these overlapped quantitative trait loci related to reproductive traits, growth, feed efficiency, meat quality, fatty acid profiles and immunity. In addition, 545 genes were identified in regions harboring selection signatures. Within this group, 58 genes were associated with growth, muscle and adipose tissue metabolism, reproductive traits or the immune system. Using relative extended haplotype homozygosity to analyze high-density single nucleotide polymorphism marker data allowed for the identification of regions potentially under artificial selection pressure in the Nellore genome, which might be used to better understand autozygosity and the effects of selection on the Nellore genome.

Whole grains of sorghum, maize, and parboiled rice were used to produce functional flours processed by twin-screw extrusion cooking, then, they were used in gluten-free bread (GFBs) to compare with whole and refined wheat breads (control 1 and control 2 respectively). The breads were evaluated for total phenolic compounds (TPC), antioxidant capacity (ABTS+ ), total condensed tannins (TCT) and phenolic acid profile (PAs) by high performance liquid chromatography. The sorghum and sorghum-corn (1:1) breads, despite being processed by extrusion and baking, showed high amounts of TCT and ABTS+ cation scavenging capacity when against control 2. In addition, high PAs retention and high antioxidant capacity (ABTS+ ) were found in GFBs such as sorghum (protocatechuic, 4-hydroxybenzoic, vanillic, caffeic, and chlorogenic), sorghum corn blend (pcoumaric and ferulic) and multicereal bread (synaptic acid). This could evidence the extrusion process facilitated the release of TPC and PAs that are bonded to the whole grain bran, through membrane softening and shear mechanisms. However, TPC retentions were similar between GFBs and whole wheat bread, due to the predominant phenolic acids in whole wheat bread such as catechin (flavonoid) and synaptic acids. |
