Managing lameness in cattle can mean tough decisions

In cow calf production, lameness is second only to reproduction for culling criteria. It impacts all levels of the production cycle, and in the long term, it can become an animal welfare issue. Cow-calf producers must prevent and treat lameness and provide an area with feed and water close by where convalescence can occur. If […] Read more

Climate change will have negative effects on animal health

We can expect climate change to have effects on animal health in many different ways. Indeed, there is already evidence that the warming and altered climate affects disease dynamics in important ways.  At its most basic level, climate change has increased global temperatures, and this will continue and accelerate, given our current trajectory. Heat stress […] Read more
