Background:  Access to sheep genome sequences significantly improves the chances of identifying genes that may influence the health, welfare, and productivity of these animals.   Methods:  A public, searchable DNA sequence resource for U.S. sheep was created with whole genome sequence (WGS) of 96 rams.  The animals shared minimal pedigree relationships and represent nine popular U.S. breeds and...

Twenty-seven sheep of the four most common Swiss breeds and the English breed Poll Dorset were experimentally infected with a northern European field strain of bluetongue virus serotype 8 (BTV-8). Animals of all breeds developed clinical signs, viremia and pathological lesions, demonstrating that BTV-8 is fully capable of replicating and inducing bluetongue disease (BT) in the investigated shee...

BACKGROUND Over the past 15 years, 300 out of 6000 breeds of all farm animal species identified by the Food and Agriculture Organization of the United Nations (FAO) have gone extinct. Among cattle, many Podolian breeds are seriously endangered in various European areas. Podolian cattle include a group of very ancient European breeds, phenotypically close to the aurochs ancestors (Bos primigeniu...

Genetic improvement programs may improve disease resistance in animal production. The best-characterized genetic control of disease resistance and immune response in animals is the one associated with the Major Histocompatibility Complex (MHC). The ovine lymphocyte antigenof DRB1 gene encodes cell surface glycoproteins that initiate immune responses by presenting processed antigenic peptides to...

selective signatures in whole genome can help us to understand the mechanisms of selection and to identify the genomic regions that have been under natural or artificial selection during long years. the objective of this study was to identify the genomic regions that have been under artificial and natural selection in baluchi and zel sheep breeds. 143 sheep from baluchi (n=96) and zel breeds (n...

Previous studies on mitochondrial DNA analysis of sheep from different regions of the world have revealed the presence of two major- A and B, and three minor- C, D and E maternal lineages. Lineage A is more frequent in Asia and lineage B is more abundant in regions other than Asia. We have analyzed mitochondrial DNA sequences of 330 sheep from 12 different breeds of India. Neighbor-joining anal...

approved: Ralph/Bogart Redacted for Privacy A total of 902 plasma samples from the Rambouillet, Targhee, Columbia, Lincoln, and Suffolk breeds of sheep were analyzed for transferrin type by disc electrophoresis. Six transferrin types, TfA, TfB, TfC, Tfp, TfE, and TfP, were found in the Rambouillet, Targhee, and Columbia breeds while five, A, B, C, D, E, and four, A, B, C, D, types were observed...

Lipska sheep is an autochthonous Serbian population from the group of Pramenka (Zapfel) sheep, bred in area around Smederevo, Pozarevac and Mladenovac. The average weight male animals (BW) 95 kg 62 female animals. Other measurements are: wither height (WH) 74 cm, body length (BL) 78 chest width (CW) 23 depth (CD) 40 cm hearth girth (HG) 91 cm. In last sixty years, adult gained ten kilograms wei...

Introduction: In the Czech Republic, there is a deficiency of selenium in sheep due to its low level occurrence soil, thus fodder. Selenium these animals can manifest number diseases. Therefore, should be supplemented with preparations containing vitamin E, because Se closely related which plays an important role immune system. Aim: The aim study was assess status selected breeds Republic and d...
