Cattle population history, breeding systems, and geographic subdivision may be reflected in runs of homozygosity (ROH), effective population size (Ne), and linkage disequilibrium (LD) patterns. Thus, the assessment of this information has become essential to the implementation of genomic selection on purebred and crossbred cattle breeding programs. In this way, we assessed the genotype of 19 cattle breeds raised in Brazil belonging to taurine, indicine, synthetic crossbreds, and Iberian-derived locally adapted ancestries to evaluate the overall LD decay patterns, Ne, ROH, and breed composition. We were able to obtain a general overview of the genomic architecture of cattle breeds currently raised in Brazil and other tropical countries. We found that, among the evaluated breeds, different marker densities should be used to improve the genomic prediction accuracy and power of genome-wide association studies. Breeds showing low Ne values indicate a recent inbreeding, also reflected by the occurrence of longer ROH, which demand special attention in the matting schemes to avoid extensive inbreeding. Candidate genes (e.g., ABCA7, PENK, SPP1, IFNAR1, IFNAR2, SPEF2, PRLR, LRRTM1, and LRRTM4) located in the identified ROH islands were evaluated, highlighting biological processes involved with milk production, behavior, rusticity, and fertility. Furthermore, we were successful in obtaining the breed composition regarding the taurine and indicine composition using single-nucleotide polymorphism (SNP) data.

Abstract: In regions where the poor rainfall distribution reduces the availability of food to feed the herds, sorghum hybrids present as a viable forage resource to prolong the forage supply in the field. This study evaluated the morphogenetic characteristics of sorghum hybrids under grazing frequencies managed under intermittent stocking with sheep. The experiment was conducted at Núcleo de Ensino e Estudos em Forragicultura, Fortaleza-CE. The treatments were combinations between hybrids of Sorghum for grazing (BR and CM) and two grazing frequencies (60 and 80 cm canopy height), in a 2 x 2 factorial randomized block design, with four replications. Higher leaf elongation rate was observed in CM hybrid pastures and in the 60 cm frequency. The stem elongation rate was higher in BR hybrid pastures and in the first regrowth cycle. The leaf appearance rate was higher in CM hybrid pastures, in the 60 cm frequency and in the second regrowth cycle. The CM hybrid presented higher leaf elongation and appearance rates and lower stem elongation rate when handled in the coastal region under dry conditions, presenting as a grass with good morphogenetic characteristics for use under grazing by sheep. |
