Purebred Ayrshire females were assigned to two groups based on the breed of fetus carried during gestation. In group 1, Limousin embryos were transferred nonsurgically into Ayrshire recipients (10 heifers and 1 cow), and in group 2, 11 Ayrshire heifers and 1 cow were inseminated artificially to Ayrshire bulls. Blood samples were collected daily from d 265 of gestation until d 15 postpartum from...

Normally, Cdk5 kinase, a Ser/Thr kinase of the cyclin dependent kinase family is essential for neuronal development, neuronal migration, cortical layering, synapse formation and behavioral functions [2]. The kinase targets a large number of neuronal protein substrates with proline directed Ser/Thr residues, which accounts, in part, for its importance in the nervous system. Its role stems from i...

Bovine venereal campylobacteriosis, caused by Campylobacter fetus subsp. venerealis (Cfv), is regarded as one of the major threats to the cattle industry around the world.
