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.

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.

Many programmed breeding programs have been introduced to synchronize estrus and ovulation and minimize time spent for heat detection.

There is need for building more "clocks" - dairies where management and business succession go hand in hand with the transfer of assets and land.

A systematic comparison of the benefits of robotic milking systems and new traditional milking systems.

The Dairy Production Skills Certificate is an introductory level certificate aimed at current dairy production workers and producers who want to learn new strategies and technologies, recent high school graduates who are seeking careers in the dairy industry; and new dairy employees who need training to become productive members of the farm team. It is specifically designed for current and beginning dairy workers.
