Geographical Distribution of Dairy Cattle in Boyolali

Geographical distribution of vampire bat-related cattle rabies in Brazil.

Seventy-seven rabies virus (RV) isolates originating from Brazilian cattle were genetically characterized. Partial nucleoprotein gene sequences of these isolates were phylogenetically and geographically analyzed. Cattle isolates, which clustered with the vampire bat-related RV group, were further subdivided into nine genetic subgroups. These subgroups were distributed widely in lowland regions,...

Inbreeding in Dairy Cattle

Inbreeding is defined as half of the genetic relationship between an animal’s parents. For example, the offspring from a mating of animals A and B, which have the same father, will have 12.5 percent inbreeding, because the genetic relationship between A and B is 25 percent. Statistical methods to select the best sires of each generation have been developed, making it feasible to achieve any pos...

Longevity in Dairy Cattle

Longevity of productive life in dairy cattle is a characteristic difficult to evaluate. This measurement is complicated, in part, because the phenotype is expressed late in the life of the animal, but also because the methods of evaluation are complex. The molecular bases of longevity are still far from being fully understood, although some genes begin to be associated with this characteristic....
