Animal health is still a major concern for many industries of meat production. A bad start not only has negative health consequences but could also cause increased treatment costs and declines in growth performance.
Several factors can negatively affect the immune system of animals, such as environmental conditions such as heat and cold stress, malnutrition, and exposure to the pathogen. There are many firms like feedworks that provide calf health care.

The fantastic thing is that there are simple handling practices that may be implemented to help minimize calf illness.
Dam nutrition and herd immunity
Meeting a dam's nutrient requirements during pregnancy is critical to placing a calf up for a good start. Research indicates poor nutrition during pregnancy can affect the growth of calves.
Dam nutrition not only impacts calf growth, but also colostrum quality. Nutritional requirements change throughout pregnancy, with requirements at their peak during the last trimester and through lactation.
Calfhood vaccinations are a simple tool for causing calf immunity to commonly occurring diseases that can arise through the beef production system, such as clostridial diseases and bovine respiratory disease (BRD).
Vaccination against the pathogens responsible for these diseases is imperative to encourage antibody production in young athletes.
Vaccinations allow the constitution of antibody memory cells, which may provide protection from these types of pathogens if they are struck later in life.It is important to maintain herd immunity by vaccinating replacement heifers when cows enter the herd.
