“…Of particular interest for understanding how convergent evolution can act in livestock populations is the existence of several different PRLR mutations that can produce the ‘slick’ phenotype in Criollo cattle [ 73 ]. Mutations in the bovine PRLR gene can have major effects on the length and the structure of hair coats providing improved thermotolerance and concomitant increases in fertility and milk yields in cattle populations that inhabit dry and tropical conditions [ 18 , 69 , 74 ]. In addition, it has been shown that these mutations can act pleiotropically and cause other physiological changes [ 75 ].…”

Criollo cattle, the descendants of animals brought by Iberian colonists to the Americas, have been the subject of natural and human-mediated selection in novel tropical agroecological zones for centuries. Consequently, these breeds have evolved distinct characteristics such as resistance to diseases and exceptional heat tolerance. In addition to European taurine ( Bos taurus ) ancestry, it has been proposed that gene flow from African taurine and Asian indicine ( Bos indicus ) cattle has shaped the ancestry of Criollo cattle. In this study, we analysed Criollo breeds from Colombia and Venezuela using whole-genome sequencing (WGS) and single-nucleotide polymorphism (SNP) array data to examine population structure and admixture at high resolution. Analysis of genetic structure and ancestry components provided evidence for African taurine and Asian indicine admixture in Criollo cattle. In addition, using WGS data, we detected selection signatures associated with a myriad of adaptive traits, revealing genes linked to thermotolerance, reproduction, fertility, immunity and distinct coat and skin coloration traits. This study underscores the remarkable adaptability of Criollo cattle and highlights the genetic richness and potential of these breeds in the face of climate change, habitat flux and disease challenges. Further research is warranted to leverage these findings for more effective and sustainable cattle breeding programmes.

“…Lactating slick Holstein cows had lower rectal and vaginal temperatures and respiratory rates during summer compared to non-slick contemporaries ( Dikmen et al, 2008 , 2014 ). Slick-haired Criollo Limonero non-pregnant heifers had lower rectal temperature and respiratory rates than normal-haired heifers ( Landaeta-Hernández et al, 2021 ). Pre-weaned Holstein calves and growing heifers carrying the SLICK1 allele also maintained lower rectal temperature when exposed to high-humidity heat during summer ( Carmickle et al, 2022 ).…”

“…The cattle that were brought to the Americas from Iberia in the 15 th and 16 th centuries were adapted to Mediterranean agroecologies and, over the succeeding centuries, these populations have evolved adaptations to tropical and arid environments, emerging as distinctive breeds with unique heat tolerance and disease resistance traits [11,[21][22][23][24][25][26][27][28][29]. Despite this, Criollo cattle are not highly valued in modern production systems and are slowly being replaced with more productive commercial breeds, which is eroding indigenous cattle genetic resources in South and Central America [30][31][32].…”

Criollo cattle, descendants of animals brought by Iberian colonists to the Americas, have been subject to centuries of natural and human-mediated selection in novel tropical agroecological zones. Consequently, these breeds have evolved distinct characteristics such as resistance to disease and exceptional heat tolerance. In addition to European taurine (Bos taurus) ancestry, it has been proposed that gene flow from African taurine and Asian zebu (Bos indicus) cattle has shaped the ancestry of Criollo cattle. In this study, we analysed Criollo breeds from Colombia and Venezuela using whole genome sequencing data to examine population structure and admixture at very high resolution. We did not detect evidence of African taurine admixture in Criollo cattle; however, there was evidence of longstanding zebu ancestry in one breed (Hartón del Valle). In addition, we detected selection signatures associated with a myriad of adaptive traits, revealing genes linked to thermotolerance, reproduction, fertility, immunity, and distinct coat and skin coloration traits. This study underscores the remarkable adaptability of Criollo cattle and highlights the genetic richness and potential of these breeds in the face of climate change, habitat flux, and disease challenges. Further research is warranted to leverage these findings for more effective and sustainable cattle breeding programmes.
