A synergistic combination of two next-generation sequencing platforms with a detailed comparative BAC physical contig map provided a cost-effective assembly of the genome sequence of the domestic turkey (Meleagris gallopavo). Heterozygosity of the sequenced source genome allowed discovery of more than 600,000 high quality single nucleotide variants. Despite(More)
The turkey (Meleagris gallopavo) is an important agricultural species and the second largest contributor to the world’s poultry meat production. Genetic improvement is attributed largely to selective breeding programs that rely on highly heritable phenotypic traits, such as body size and breast muscle development. Commercial breeding with small effective(More)
Semen cryopreservation is necessary for banking germplasm from critical poultry stocks. To date, glycerol is the most effective cryoprotectant for poultry sperm; however, the contraceptive effects of glycerol require a significant reduction of the cryoprotectant from thawed semen before artificial insemination (AI). The effectiveness of glycerol reduction(More)
Dendritic cells (DC) play a prominent role in the development of T cell-immune responses to antigens and have a key influence over the differentiation of naive T cells into T helper cell type 1 (Th1) or Th2 effector cells. Consequently, there is considerable interest in pharmacological agents that might alter DC function and thereby modulate allergic(More)
Avian semen cryopreservation is an invaluable reproductive strategy for conserving desirable genetic traits for commercial poultry production and endangered species conservation. Here we provide the effects of including sialic acid (SA) in the cryodiluent for tom and rooster sperm cryopreservation. Tom and rooster (n=6 males/treatment) semen was incubated(More)
The fertility rates of cryopreserved poultry semen are highly variable and not reliable for use in preservation of commercial genetic stocks. Our objective was to evaluate the cryosurvival of semen from 8 pedigreed layer lines at 2 different ages: the onset and end of commercial production. Semen from 160 roosters (20/line) was frozen individually with 11%(More)
The domestic turkey (Meleagris gallopavo) is an important agricultural species that is largely used as a meat-type bird. Characterizing genetic variation in populations of domesticated species and associating these variation patterns with the evolution, domestication, and selective breeding is critical for understanding the dynamics of genomic change in(More)
