Most veterinarians and dairy producers are familiar with the use of blood mineral concentration determinations as an aid in disease diagnosis. Although it is useful to know what is responsible for a disease process, a preferred option is to determine if a cow is metabolically unstable and will ultimately succumb to some disease process.

We are all aware of the dire constraints we may be facing this winter because of the dramatic increases in the prices of all forms of energy, except electricity. Fortunately, the autumn weather has been quite mild thus far, so we have not needed too much fuel for space heating purposes yet.

How would you rate the respectability of your dairy farm in relation to your environment, neighbors, cows and workers?

Leptospirosis is a worldwide infectious bacterial disease of many animal species causing abortion, stillbirths, milk loss and reproductive inefficiency. Leptospiral organisms can infect humans, thereby becoming an important zoonotic disease.

Automatic cluster removers determine when the milk flow rate is low enough to detach the milking machine from the udder. Use of this equipment allows greater consistency than is possible with manual machine removal and also allows for a reduction in labor.

Best Management Practices (BMPs) for controlling odors from farms with animals are being proposed as part of the new ACRE program.

Evaluating the feed bunk of high producing dairy cattle is important to help determine if they are being fed in a manner that meets their nutrient needs. Your feeding system along with your feeding strategy, or the way you manage the system, is crucial to providing the majority of your cows with balanced diets in adequate amounts.

When we discuss the effect of lameness on reproductive performance we generally focus on the concept that lame cows are generally less likely to engage in mounting activity. Cows need sound feet and legs to seek out cows in heat, mount them or be mounted if they are in heat themselves. If this basic requirement is compromised then efficiency and accuracy of heat detection will be low. On average, cows are in heat for approximately 7 to 8 hours. This is a narrow window of opportunity to detect healthy cows in heat and presents a real challenge to detect lame cows in heat.

Many PA locations have high wind speeds during the winter months but the minimum wind speed needs to be maintained throughout the summer months as well when electricity is most valuable.

Penn State researchers have developed a program to help you train employees responsible for calf care. The CalfTrack calf management training system includes standard operating procedures (SOPs) for many calf care tasks, an orientation video, a health scoring system, and a detailed reference manual. In addition, most materials are available in both English and Spanish.
