In the United States, feeding a total mixed ration, using antibiotics as dry cow therapy, housing in freestalls, and bedding with sand or sawdust are typical management practices. However, during a study abroad trip, 8 University of Kentucky students learned that on dairies in the Netherlands, producers manage differently.
The goal of any dairy producer is to maximize milk production while producing quality milk. Somatic cell count or SCC is a universal method to determine presence of an infection based on the number of somatic cells within the milk. A low SCC is one measure of milk quality within a herd. However, there may still be evidence of milk quality issues even when SCC is low. The preliminary incubation(PI) count is a unique test that has the ability to detect bacteria that grow in cold environments called psychrotrophic bacteria.
Lameness in dairy cows is one of the major issues in the dairy industry. Lameness can cause pain to the cows, which in return, can decrease milk yield, fertility and longevity. This decrease in productivity can cause serious economic loss. The economic loss per cow due to lameness is calculated to be about $220. Many factors influence lameness. One common influences includes poor flooring surfaces in the barn in which cows are housed as well as the holding pen.
