Edited by Dr. Jud Heinrichs, Professor of Dairy and Animal Science, Dairy Digest features articles by Penn State's experts in dairy management, engineering, herd health, and related areas. Dairy Digest has been published by the Department of Dairy and Animal Science and Penn State Cooperative Extension since 1963.
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.
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.
As producers look at options for their dairy rations in light of increased feed costs, it's important to consider the relationship between changes in milk price and feed costs on dairy profitability and cash flow.
We think we have it tough finding dairy employees in Pennsylvania, but we ain't seen nothin' yet!
The age at which you decide to wean a dairy calf will have a definite impact on the cost of raising that calf.
It is critical that you know the sulfur content of the fuel that you are using in your diesel engines on the farm.
Effect of dry propylene glycol vs. drenching: a preliminary report.
An experiment currently in progress is evaluating the effects of feeding dry glycerin to early lactating Holstein dairy cows. Some of these strategies include the use of glucose precursors like glycerin and propylene glycol. Glycerin may improve energy supply in early lactation dairy cows.
About 80 percent of this loss occurs before day 17, 10-15 percent between day 17 and 42 and 5 percent after day 42.
A good housing system for calves and heifers will provide for the well-being of animals of various ages, promote safe and efficient working conditions for the caretaker, protect the environment and be cost-effective to build and maintain.
A summary of some of the new and interesting findings that affect calf health, feeding, and management.
A new book, Penn State Housing Plans for Milking and Special Needs Cows is now available.
Warm sunny spring days feel nice after cold winter nights. For many of our cows these days are already the harbinger of uncomfortable hot weather to come.
Dairy cows are at risk of becoming heat stressed more than most animals because with genetic selection for milk yield the cow has a high internal heat production.
Penn State Extension dairy educators across the state as well as faculty and staff from Penn State University’s departments of Agricultural and Biological Engineering, Dairy and Animal Science, Crop and Soil Sciences, and Veterinary and Biomedical Sciences have combined their expertise to create an innovative program designed to identify key opportunity areas limiting the profitability of Pennsylvania dairies.
