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.
Besides the somewhat similar spelling of their names, do these diseases have anything in common?
It is worth reviewing once again the requirements for success that are common to all systems.
Subclinical, or chronic, ruminal acidosis is best described as a syndrome related to a fermentative disorder of the rumen.
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.
