Scours prevention tips for dairy calves
Two keys to prevention: maximize immunity and minimize exposure.
Give first-calf heifers a boost
First-lactation animals make up a third or more of the typical U.S. dairy herd, so their health and performance is paramount to operational success.
Identify and manage persistently infected calves
Bruce Hoffman, veterinarian and president of Animal Profiling International, offers tips for managing bovine viral diarrhea.
Heifers and mastitis
Heifers that contract mastitis are usually detected after freshening or sometime in early lactation. However, these animals could have had an intramammary infection for more than a year before being diagnosed. Milk-producing tissue in the udder develops during the first pregnancy, making it extremely important to protect heifers from mastitis pathogens.
Why do vaccines fail?
New BVDV resources
A new online bovine viral diarrhea virus information resource is available.
Transition period can reduce respiratory illness
Too many changes at eight weeks of life cause stress, reduce immunity and cause respiratory problems in calves, explains Al Kertz, nutritionist with ANDHIL LLC.
USDA grants $16.8 million for TB eradication efforts
Protect heifers from BVD infection
Can you assure your clients that their heifers — and their unborn calves — will return home without any new infectious diseases?
How to avoid endotoxin overload in calves
Avoid endotoxin overload in calves through proper vaccine handling and other strategies.
Mastitis prevention begins at birth
Anytime a heifer freshens with mastitis, you failed somewhere earlier in life.
These two viruses commonly found
Whether or not these two pathogens cause severe, mild, or even no clinical cases of diarrhea in calves depends on your management.
Keep vaccine expectations realistic
Your first concern should be to choose those that do no harm.
Control winter teat problems
Learn why bacteria doesn’t stop growing in stall beds even in the winter.
Check calves’ ears when resting
Calves in the early stages of mycoplasma pneumonia will perk up their ears at feeding time, too.
Keep calves’ routine consistent
Doing so can help prevent clostridium problems in calves
