By Dan Leiterman
Preface: This is the first part of a two-part article addressing my thoughts about common sense strategies for dairy nutrition.
Throughout the ages and in all walks of life, mankind has demonstrated a relentless and instinctive desire to learn, to explore and to discover answers for the many complex mysteries of life and science. The quest for knowledge is essential to our success as a species. However, managing the new knowledge and applying it to our benefit is an ever-increasing challenge. During our journey to learn as much as we can, it is important to remember the role of simplicity as an essential tool to help us manage the overwhelming amount of information we are exposed to every day. No matter how complex the topic, it must adhere to simple, basic and sound principles so information can be applied easily and efficiently with balance. If simplicity is not taken into account, it is too easy to lose perspective on the task at hand, forget the lessons of history, and become lost in a sea of data. Information that is consistent with simple principles will advance a cohesive, wise and efficient strategy that helps us to reach a sustainable goal. Keeping a solid tie to simplicity can provide clarity and help us stay on course in the growing complexity of our world.
How to Effectively Manage High Somatic Cell Counts

By Teresa Marker, B.S.
Herd-wide high somatic cell count (HSCC) issues can negatively impact both milk quality and overall farm profitability. A recent study estimated that the cost of subclinical mastitis to the U.S. dairy industry exceeds $1 billion annually. The overall production loss for the average U.S. dairy farm was estimated at $110/cow annually. This loss can be attributed to discarded milk, treatment costs, extra labor costs, milk production losses, culling and death loss. The following article will outline what steps are needed to determine the cause of a high somatic cell count, how to interpret diagnostic test results and how to create a plan to help reduce the overall herd somatic cell count.
Water Hygiene: How often Do You Think About It?

Water is the most critical nutrient for all animals, but how often do people think about it? Would you drink out of your animal’s water trough? Research shows that poor water quality dramatically reduces water consumption, which in turn lowers production and deteriorates overall animal health. A common cause of poor water quality is biofilm formation. Preventing biofilm formation and improving water quality can be done at a low cost while providing a high return on investment for farms.
The Impact of Fly Pressure and the Importance of Fly Control

By Alex Austin, B.S.
When winter is over and warm weather arrives, it is goodbye to plowing snow and dealing with frozen water and hello to green pasture and sunshine. The warmth of spring and summer can present new challenges with the hatching fly population. Livestock owners know flies cause pain and discomfort to animals but they can also have a negative economic impact. It is important to enter the summer season with an effective fly control plan in place to maintain animal health and minimize fly pressure effects on producer profitability.

By Teresa Marker, B.S.
Feeding high-quality forage to livestock can help improve animal performance, health and producer profitability. Properly inoculating livestock feedstuffs with an inoculant that provides complete and controlled fermentation is key. The Crystal Creek® product Inoc-U-Lock™ provides many benefits such as reduced dry matter loss, improved nutrient retention (protein and energy) during storage, improved aerobic stability and a reduced risk of heating in the bunk. A properly fermented feed preserves the quality of the forage that is harvested and can ultimately result in increased milk production and improved animal health.

When discussing calf barn ventilation, invariably the topic of using four air exchanges per hour for cold weather ventilation will come up. After all, we wouldn’t want “too much” of that cold air in the barn. Or would we? Who came up with the idea to use four air exchanges per hour during cold weather and why? To understand our industry’s current ventilation recommendations, we must first understand the history of calf barn ventilation research.
Cold Weather Considerations For Calves

When temperatures start to drop, calf raisers need to make accommodations to ensure calves have the resources necessary to maintain their body temperature, support basic bodily functions and develop into productive, profitable, young stock. Two general areas to consider when preparing your calves for winter months are diet/nutrition and housing.
