the production of quality milk |
|
history records cows being milked as far back as 9000 b.c. in florida, cows have been milked since the settlement of st. augustine in 1565. however, it was not until colonial times in 1611 that dairy cows arrived in jamestown. from that time until 1850, dairying changed very little. most cattle were dual purpose (used for dairy and beef purposes) and were kept to satisfy family food needs. milk and dairy products were in short supply and for the most part unavailable to those not living on or near the farm.

Pharmacology and Cows |
|
Milk and meat are our products, but we work with animals, living beings that require care and management to ensure their welfare. One of our tools includes medications.
In the U.S. in order for a drug to be used legally in dairy cows or other animals (including human beings), it must be approved for use by the FDA. In addition, for drugs to be used in food animals, the manufacturer must perform tests to determine appropriate posttreatment periods in which milk, meat, or both cannot be sold or consumed. For new drugs, the testing required to gain FDA approval typically takes many years and costs millions of dollars.

Swine Health Program |
|
Swine disease outbreaks are often related to a high concentration of pigs raised continuously in the same facility or accumulation of disease producing organisms in the environment. These organisms can keep reinfecting the herd. In addition, the movement of hogs from farm to farm can introduce new infectious disease-producing agents into the herd.

Reproductive Anatomy and Physiology of dairy Cattle |
|
Optimal reproductive performance is fundamental to profitability of the dairy enterprise. Consequently, it is the focal point of dairy management and veterinary health programs on most successful dairy operations. When the average age of heifers at first calving is 24 versus 30 months, lifetime milk production potential is increased and replacement rearing costs decrease substantially.
