Researchers at UC-Davis have developed a handy, easy-to-use diagnostic tool to streamline monitoring of calves for respiratory disease, so they can be detected and cared for early in the disease process.
Because of a slow, six-to eight-week incubation period, anaplasmosis often turns up in cattle herds around this time of year, as the disease emerges in herds exposed to ticks or other vectors during the summer.
Modified live vaccines can be effective in building immunity in cattle, because they stimulate an immune response to a variation of disease-causing organisms. But those live organisms can be touchy and temperamental.
Agriculture on the Great Plains in the coming decades may be adversely affected by a shifting of the climate boundary due to global warming, says Richard Seager, a climate scientist at Columbia University.
