Timely and accurate determination of pregnancy status is crucial to a successful reproductive management program.
Achieving a tight pack is one of the most important aspects of harvesting and storing silage.
The PA Johne’s Disease Herd Certification Process (JDHCP) is based on the national program standards, which were developed by the USDA and the National Johne’s Working Group in an effort to bring uniformity to the Johne’s programs being developed by individual states.
The January 10, 2006 issue of the Hoard’s Dairyman contained a short article about the National Dairy Quality Award winners.
Evaluating and monitoring dehydration in your dairy calves is an important task for the dairy calf manager.
EPA has taken a giant step in the expected regulation of air emissions (especially ammonia) from AFOs (animal feeding operations) including dairies.
Are you one of the many producers who have been practicing good conservation for at least the past few years? Now a new USDA program, the Conservation Security Program (CSP), is available to reward you for your efforts.
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.
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.
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.
Antibiotics are used in livestock production as therapeutics, growth promoters, and prophylactics.
Observing the health status of a dairy calf is an important part of being a competent calf raiser.
A new fact sheet titled “Nitrogen, Ammonia Emissions and the Dairy Cow” (DAS 04-87) is available from dairy and animal science.
