In the old version, we released "Comparative Genomics" tracks (only for goat) that including 67-species synteny (47 de novo, 8 published ruminant genomes, and 12 outgroup species genomes) and five scales of measurements of evolutionary conservation to help analyze protein-coding genes, identify regulatory elements, reveal similarities and differences among species, and trace the course of evolution. With the rapid development of third-generation sequencing technology, genome quality has been greatly improved. We updated the "Comparative Genomics" tracks that providing 110-species synteny for three major livestock (cattle, sheep, and goat), 31 of which were assembled by third-generation sequencing technology. And also, in the latest version, we have added four-species new genome browsers, covering the genomes of all available domestic animals of the suborder Ruminantia. A wealth of epigenomic data, RNA-seq data, QTL and QWAS dataset are integrated into these genomes, providing functional annotations.
