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.
Technology takes monitoring cows at calving time to a new level.
Five steps to monitoring the financial health of a dairy business.
Overmilking can damage teat ends and compromise udder health. A simple test can help you determine if you are over or under milking.
Description of in-feed medications and how they fit into the new Veterinary Feed Directive rules taking effect January 1, 2017.
An example of how one farmer is using data from an activity monitoring system to identify the optimum breeding time for his farm.
Results of monitoring THI, rumination, and milk production on a Southeastern Pennsylvania farm.
Enacted to further improve the safety of our food supply, these laws will impact most farms.
Feed costs tend to be the largest expense on a dairy operation and managing those costs contributes to a dairy’s ability to be profitable.
Precision feeding is a strategy for productive heifers and a healthy bottom line. The Penn State Dairy Heifer Diet Formulator (PSU-HDF) program encourages an approach to heifer feeding that is driven by the desire to precisely meet metabolizable energy and nitrogen needs of growing dairy heifers while still allowing farmers to meet their desired goals for growth, age at first breeding, age at first calving, and first lactation production.
Future milk prices are looking (somewhat) better, but it seems like since 2008 no one has felt completely secure in the stability of the dairy industry. Being more cautious can be a good thing, but letting the milk prices and low milk margins get you down is not healthy for you, your family, or your farm in the long run. There is plenty of advice on how to manage your margins and your herd. Now, it is time to talk about how to manage your stress.
When data is available, managers can look at mortality numbers, feed shrink (tons harvested or purchased compared to as fed), and inventories of supplies to determine what changes if any are needed to reduce these sometimes steady drains on profitability.
A typical discussion of farm safety may focus on equipment operation principles, the use of personal protective equipment, or safe animal handling, but there are other aspects of farm safety that we sometimes neglect to include in our discussions.
We have recently updated an article about trends in age at first calving using records obtained from DRMS for all first-lactation Holsteins in Pennsylvania during 2015.
In 2015, over half of the milk produced in the U.S. came from five states: California, Wisconsin, Idaho, New York, and Pennsylvania.
Structures that house cattle are vital to the success of a dairy business.
Shredlage has been a hot topic in recent years, but studies have demonstrated it has the same overall dry matter and fiber digestibility as conventional silage.
It is increasingly common for dairy managers to use tools that allow for pregnancy diagnosis earlier than the traditional 35 to 45 days after insemination. Diagnosing pregnancy early is beneficial for identifying open cows and allowing for reinsemination strategies that will help minimize days open and increase profitability, but losing confirmed pregnancies can be very frustrating.
The Penn State Extension Dairy Business Management Team summarizes Pennsylvania dairy cash flow plans annually to assess the factors that lead to farm profitability. In 2015, the 105 farms in the summary were divided by farm size to determine if there are any benefits to larger-scaled farms.
An examination of 2015 cash flow and breakeven production costs for 107 Pennsylvania farms shows that breakeven ranged from less than $16/cwt to over $22/cwt. Not surprisingly, feed costs are a big contributor to differences between farms.
Understanding differences between cultures can provide helpful insight for situations encountered everywhere in our increasingly global society, including common encounters on U.S. farms.
