Understanding milk flow patterns of individual and groups of cows can help you to evaluate how well people, cows, and equipment are doing in harvesting milk on your dairy.
The Animal Improvement Programs Laboratory at USDA recently published a comprehensive analysis of the trends in age at first calving and calving intervals for the five breeds of dairy cattle from 1980 to 2004 (J. Dairy Science, Jan. 2006). These are important factors contributing herd profitability and reproductive management has become a major challenge to many dairy producers.
Having clear and concise job descriptions in place is vital for employee success on the farm. But even though job descriptions are important, most producers don’t want to take the time to write them.
Oral rehydration solutions are used to replenish fluids and electrolytes that are lost during the course of diarrhea. Also known as electrolytes, these solutions are a convenient way to treat calves with diarrhea.
Results of this study showed that the heifer raising operation could serve as a clearing house of S. Typhimurium var Copenhagen and perhaps other Salmonella serotypes.
One can get a whole new perspective while trying to locate a new dairy complex on a proposed site.
Most veterinarians and dairy producers are familiar with the use of blood mineral concentration determinations as an aid in disease diagnosis.

We are all aware of the dire constraints we may be facing this winter because of the dramatic increases in the prices of all forms of energy, except electricity. Fortunately, the autumn weather has been quite mild thus far, so we have not needed too much fuel for space heating purposes yet.
Diagnostic tests such as the Johne’s ELISA are used to tell us something about the “true” status of the animals being tested.
Updated dairy idea plans that include up-to-date research and field observations related to dairy cattle freestall design, dimensions and construction.
