Flies are just as annoying to cows as they are to people. But two types of flies cause actual discomfort for cows – stable and biting flies. Both of these flies bite and draw blood. Here are some tips for recognizing and controlling them.

Why is cow cooling important? Cooling dairy cows is important for several reasons. Cows enjoy temperatures in the range of about 40°F to 68°F. At temperatures above this range, cows use more energy to get rid of the excess heat. To get this additional energy, the cow must either eat more feed, use less energy for milk production or reproduction or convert body fat reserves to energy.

Cavitation is called the cancer of the hydraulic system. Like cancer in humans, it can be a silent killer of your system by eating away at the hydraulic pump and other parts of the system.

Are you doing the “little things” at your dairy to take your bulk tank from 70 to 80, 80 to 90, or 90 to 95 pounds of high-quality milk per cow per day? Cows and their environment Milk quality starts with providing a clean, dry, comfortable environment. When was the last time you did a cow comfort audit? When was the last time you stopped, looked and listened to your cows in their resting place? While spending time watching and listening to your cows get up in the stalls, do we see cows standing idle (standing with all four feet in the stall)? Do we see cows “perching” (two feet in the stall and two feet in the alley) or cows lying diagonally in the stall? A cow comfort audit should include an assessment of the facility for meeting the behavioral and safety needs of the cow, including signs of injury, lameness or behavioral abnormalities.

Milking equipment cleanliness and proper functionality play a big role in achieving peak milk quality. Often when producers attempt to correct problems related to high standard plate count (SPC) or protein, fat and mineral buildup in their pipeline and inflations, they find a variety of issues to blame. Such was the case with a Progressive Dairyman reader who wrote to us in search of answers.

This article was #1 in PDmag's Top 5 most-well read New Technology articles in 2010. Summary: The Greenfreestall, a division of Tags4All Global Inc., has created a freestall structure that is adjustable, movable and, most importantly, comfortable for cows. The sides of the design are made of composite flex piping and allow for increased flexibility. In addition, the structure adjusts in the following ways: • the height of the plastic tubes • the height of the neck bracket • the length of the neck bracket • the width of the bed Because this article was so popular, we asked John Moses of Greenfreestalls some follow-up questions:
