Many factors have been identified for the apparent reduction in fertility and there is no doubt the current problem is multi-faceted and not easy to resolve.
In recent months milk replacer costs have jumped $15 to $20 per bag, and we have entered into somewhat new territory in the economics of calf feeding systems.
The key performance indicator for reproductive performance is 21-day Pregnancy Rate (PR).
Based on a large data set of first services (16,587), J.M. DeJarnette and coworkers at Select Sires, Inc. compared the reproductive performance of Holstein heifers inseminated with sex-sorted semen (SS) vs. conventional non-sorted semen (CS).
At the recent annual meeting of the American Dairy Science Association, scientists from around the world presented the latest results from current research. We've summarized some of the new and interesting findings that affect calf health, feeding, and management.
Members of Penn State's Dairy Science Club were victorious in the quiz bowl competition at the 2007 American Dairy Science Association-American Society of Animal Science annual meetings in San Antonio, TX, in early July. It marks the sixth time in seven years that the Penn Staters won first place in the quiz bowl.
If you're interested in the dairy industry, you'll enjoy knowing that a collection of the first Dairy Digests, the monthly newsletter from Penn State's Department of Dairy and Animal Science, is now archived at www.das.edu/dairydigest.
All the information presented in this article is directed to dairy farmers who are classified as “commercial” or “industrial” customers of electricity. If you are classified as a “residential” customer, this article does not apply to you because your price for electricity is based on a flat (or nearly flat) rate of x cents per kWh (kilowatt-hour).
Significant changes have come to minimum wage laws. To understand how farmers are affected we must begin with laws that affect all employers.
Ohio Department of Agriculture (ODA) officials confirmed the discovery of eastern equine encephalitis (EEE) virus - a mosquito-borne viral disease - in a central-Ohio horse and a northwest-Ohio horse.
Eastern equine encephalitis and West Nile virus are transmitted by mosquitoes.
Last year, 2006, will probably be remembered as one of the most challenging years for financial performance on dairy farms. Unfortunately, 2007 is not starting off much better.
Dairy middle managers will have an opportunity to learn new management skills and strategies at the second annual Middle Manager's Conference planned March 21 in the Harrisburg-Hershey area.
All customer classes are benefiting from the declining prices of PA's electricity.
Dr. Larry Specht, professor emeritus of dairy science, has compiled a history of red and white Holsteins, which offers an overview of how the existence of red and white dairy cattle evolved in the United States when all of the early Holsteins imported from the Netherlands were black and white.
We have been hammering away at relieving heat stress on dairy cows for a long time including how to design, build, modify and manage facilities. Heat stress occurs when the heat generated by the cow and heat received by her from the environment exceeds the amount of heat the she can successfully release to her environment. SAAWW is a convenient tool for remembering the critical steps to cut heat stress.
The 2007 Spring Dinner Dance was held April 20 at the Ramada Inn and Conference Center, State College, PA.
It appears that the PA dairy industry is continuing to give this technology a good hard look and several of our dairy herds are being reliably milked with milking robots.
