Criollo and Crossbred Steer Comparison: Weight Gain, Grazing, Carcass Quality, 2015-2017
Rarámuri Criollo cows have behavioral traits that are desirable for rangelands in arid environments, but calves from this biotype are difficult to market through conventional methods. One strategy to improve marketability is to crossbreed these cows with traditional beef breed bulls. However, it is unclear whether crossbred calves will achieve marketable weights and carcass qualities on rangeland and whether they will retain the desirable grazing behaviors of their mothers. We evaluated these traits for two cohorts of Rarámuri Criollo (JRC), Mexican Criollo (MC), and Criollo × beef-breed crossbred (XC) steers. Final live and carcass weights of XC were greater than JRC and MC, but all three groups were market ready at 30-mo after finishing on grass. Carcass quality and average daily gain did not differ among biotypes. Both JRC and XC steers exhibited grazing patterns similar to those previously observed in JRC cows. These results suggest JRC, MC, and XC steers can achieve desirable slaughter weights in 30 months using a rangeland-based grass-fed protocol, and JRC and XC steers retain desirable grazing behaviors of JRC cows.
Identification of quantitative trait loci and associated candidate genes for pregnancy success in Angus – Brahman crossbred heifers
<p>Development of genomic tools to identify females with high genetic merit for reproductive function could increase the profitability and sustainability of beef production. Here, genome-wide association studies (GWAS) were performed on pregnancy outcome traits from a population of Angus – Brahman crossbred heifers. Furthermore, a validation GWAS was performed using data from another location. Heifers were genotyped with the Bovine GGP F250 array that contains ~250,000 SNPs. In the discovery population, heifers were bred in winter breeding seasons involving a single round of timed artificial insemination (AI) followed by natural mating for three months. Three phenotypes were analyzed: pregnancy outcome to first-service AI (PAI; n = 1481), pregnancy status at the end of the breeding season (PEBS; n = 1725), and pregnancy score (Pregscore where 1 = pregnant to first-service AI, 2 = pregnant to bull, 3 = not pregnant; n =1481). The heritability for PAI was estimated as 0.149. One large quantitative trait locus (QTL) that explained ~3% of the genetic variation for PAI was found on BTA7, in a region containing a cluster of γ-protocadherin genes and SLC25A2. Other QTLs explaining between 0.5-1% of the genetic variation were found on BTA12 and 25. The heritability of PEBS was estimated at 0.122. A large QTL on BTA7 was synonymous with the QTL for PAI, with minor QTL located on BTA5, 9, 10, 11, 19, and 20. Estimated heritability for Pregscore was 0.189. There was a large QTL on BTA7 synonymous with the other two traits as well as smaller QTLs on BTA1, 10, 15, 18, 19, and 20. The validation population for pregnancy status at the end of the breeding season were Angus-Brahman crossbred heifers bred by natural mating. In concordance with the discovery population, the large QTL on BTA7 and QTL on BTA10, 12 and 18 were identified. In summary, QTL and candidate SNPs associated with pregnancy outcomes in beef heifers were identified, including a large QTL associated with a group of protocadherin genes. Confirmation of these associations with larger populations could lead to the development of genomic estimates of reproductive function in beef cattle.</p>

Local ancestry to identify selection in response to trypanosome infection in Baoulé x Zebu crossbred cattle in Burkina Faso
<p><span>The genomes of crossbred (admixed) individuals are a mosaic of ancestral haplotypes formed by recombination in each generation. The proportion of these ancestral haplotypes in certain genomic regions can be responsible for either susceptibility or resistance against pathogens, and for performances in production traits. Using dense genomic markers from the Illumina Bovine SNP50 BeadChip, we estimated individual admixture proportions for Baoulé x Zebu crossbred cattle in Burkina Faso, which were tested for trypanosome infection by direct ELISA from blood samples. Furthermore, we calculated local ancestry deviation from average for each SNP across 29 autosomes to identify potential regions under selection in the trypanotolerant Baoulé cattle and their crossbreds. We identified significant deviation from the local average ancestry (above 5% and 10% genome-wide thresholds) on chromosomes 8 and 19 in the positive animals, while the negative ones showed higher deviation on chromosomes 6, 19, 21 and 22. Screening for <i>F</i><sub>ST</sub> outliers in trypanosome positive/ negative animals we detected seven variants putatively under selection. Finally, we identified a minimum set of highly ancestry informative SNPs for routine admixture testing. Generally, results will serve as basis for further characterization, conservation and improvement strategies for purebred and crossbred populations. Our results are important not only for conserving the genetic integrity in the indigenous Baoulé cattle, but also for improving community-based breeding programs to increase trypanotolerance in crossbred populations.</span></p>
