Preventive health programs for dairy cattle

Health Production Function for Preventive Health Programs

Production function studies have mainly been directed at the formal health care sector, in particular hospitals. Health production function relating medical and/or non-medical health inputs to good health, however, have not been intensively investigated. This paper explores the possibility of employing a health production function to examine the relationship between preventive health programs a...

optimization of progeny testing programs for iranian holstein dairy cattle

a deterministic model was employed to simulate various progeny testing programs compatible with the conditions of holstein dairy cattle population in iran. in simulated programs, the selection intensity of bulls was increased by increasing the ratio of cow population in mate with young bulls. selection accuracy in the programs was fixed because of the fixed progeny group. economic efficiency (t...

Trace Mineral Requirements for Dairy Cattle

A host of nutrients are needed by cattle to support functions associated with life, and to grow, reproduce, and nourish their offspring (i.e., produce milk). A vast amount of resources have been expended to quantify the amounts of specific nutrients needed to perform these function so that economically efficient diets can be formulated. Feeding diets that provide adequate, but not excessive, am...
