Association of inbreeding and regional equine leucocyte antigen homozygosity with the prevalence of insect bite hypersensitivity in Old Kladruber horse.

Anim Genet 2021 May 10. Epub 2021 May 10.

Faculty of Agriculture, University of Zagreb, Svetošimunska cesta 25, Zagreb, 10000, Croatia.

Inbreeding depression is the reduction of performance caused by mating of close relatives. In livestock populations, inbreeding depression has been traditionally estimated by regression of phenotypes on pedigree inbreeding coefficients. This estimation can be improved by utilising genomic inbreeding coefficients. Read More

Identification of quantitative trait loci associated with calmness and gentleness in honey bees using whole-genome sequences.

Anim Genet 2021 May 10. Epub 2021 May 10.

Agroscope, Animal GenoPhenomics, Rte de la Tioleyre 4, Posieux, 1725, Switzerland.

The identification of quantitative trait loci (QTL) through genome-wide association studies (GWAS) is a powerful method for unravelling the genetic background of selected traits and improving early-stage predictions. In honey bees (Apis mellifera), past genetic analyses have particularly focused on individual queens and workers. In this study, we used pooled whole-genome sequences to ascertain the genetic variation of the entire colony. Read More

Evolution of the sheep industry and genetic research in the United States: opportunities for convergence in the twenty-first century.

Anim Genet 2021 May 6. Epub 2021 May 6.

National Animal Germplasm Program, United States Department of Agriculture, Agricultural Research Service, Fort Collins, CO, 80521, USA.

The continuous development and application of technology for genetic improvement is a key element for advancing sheep production in the United States. The US sheep industry has contracted over time but appears to be at a juncture where a greater utilization of technology can facilitate industry expansion to new markets and address inefficiencies in traditional production practices. Significant transformations include the increased value of lamb in relation to wool, and a downtrend in large-scale operations but a simultaneous rise in small flocks. Read More

A natural knockout of the MYO7A gene leads to pre-weaning mortality in pigs.

Anim Genet 2021 May 6. Epub 2021 May 6.

Topigs Norsvin Research Center, Beuningen, The Netherlands.

The pig breeding system provides a unique framework to study recessive defects and the consequence on the phenotype. We examined a commercial synthetic Duroc population for recessive defects and identified a haplotype on chromosome 9 significantly affecting pre-weaning mortality. To identify the causal variant underlying the mortality, we examined sequence data of four carrier animals and 21 non-carrier animals from the same population. Read More

Parsing the microRNA genetics basis regulating skeletal muscle fiber types and meat quality traits in pigs.

Anim Genet 2021 Jun 11;52(3):292-303. Epub 2021 Apr 11.

Department of Animal Genetics, Breeding and Reproduction, College of Animal Science and Technology, Nanjing Agricultural University, Nanjing, 210095, China.

Muscle fibers are closely related to human diseases and livestock meat quality. However, the genetics basis of microRNAs (miRNAs) in regulating muscle fibers is not completely understood. In this study, we constructed the whole genome-wide miRNA expression profiles of porcine fast-twitch muscle [biceps femoris (Bf)] and slow-twitch muscle [soleus (Sol)], and identified hundreds of miRNAs, including four skeletal muscle-highly expressed miRNAs, ssc-miR-378, ssc-let-7f, ssc-miR-26a, and ssc-miR-27b-3p.

De novo assembly and annotation of the North American bison (Bison bison) reference genome and subsequent variant identification.

Anim Genet 2021 Jun 29;52(3):263-274. Epub 2021 Mar 29.

Department of Veterinary Pathobiology, Texas A&M University, College Station, TX, 77845, USA.

Genomic tools have improved the ability to manage bison populations and enhanced efforts to conserve this iconic species. These tools have been particularly useful for detecting introgression of cattle genome within bison herds but are limited by the need to use the cattle genome as a surrogate for mapping reads. This complicates efforts to distinguish the species of origin of chromosomal segments in individual bison at the genomic level. Read More

All-male production by marker-assisted selection for sex determining loci of admixed Oreochromis niloticus and Oreochromis aureus stocks.

Anim Genet 2021 Jun 19;52(3):361-364. Epub 2021 Mar 19.

Institute of Animal Science, Agricultural Research Organization, Rishon LeTsiyon, 7528809, Israel.

Crossing Oreochromis niloticus (On) females with Oreochromis aureus (Oa) males results in all-male progeny that are essential for effective tilapia farming. However, a reproductive barrier between these species limits mating and mass-fry production. One approach to overcoming this barrier is to select parental stocks of mixed genetic backgrounds, which allow interspecific reproductive recognition, while closely maintaining the genetic profiles for sex-determination (SD) of the respective purebred species.

Potential functional variants in AHR signaling pathways are associated with age at puberty in swine.

Anim Genet 2021 Jun 5;52(3):284-291. Epub 2021 Mar 5.

USDA, ARS, U.S. Meat Animal Research Center, Clay Center, NE, 68933, USA.

Puberty in female pigs is defined as age at first estrus and gilts that have an earlier age at puberty are more likely to have greater lifetime productivity. Because age at puberty is predictive for sow longevity and lifetime productivity, but not routinely measured in commercial herds, it would be beneficial to use genomic or marker-assisted selection to improve these traits. A GWAS at the US Meat Animal Research Center (USMARC) identified several loci associated with age at puberty in pigs. Read More

Department of Genetics and Animal Breeding, Poznan University of Life Sciences, Wolynska 33, Poznan, 60-637, Poland.

The equine graying with age causative mutation in the syntaxin-17 gene (STX17) has been known for over a decade, but proper genotyping of this variant remains challenging due to its molecular character (4.6-kb tandem duplication). Precise information on gray mutation status is important for horse breeders and veterinarians, since gray homozygous horses are more prone to developing aggressive melanoma tumors than heterozygotes.
