Dairies have made great strides in managing colostrum, but about 14% of calves fail to get passive transfer of antibodies. There is still opportunity to improve upon this, encourages Sandra Godden, DVM.
Barry Whitworth, Oklahoma State University Extension veterinarian recommends cow-calf operators keep several doses of colostrum or colostrum replacer handy as calving season is underway in many parts of the country.
Detecting respiratory disease in calves early – when treatment is most effective – should start by examining the head and facial features, according to veterinarian Tiago Tomazi with Merck Animal Health.
Raising an orphaned beef calf can be time consuming and may require additional expense. Additionally, calves may not be thriving at the time they are orphaned so managing health and nutrition can present challenges.
Caffeine may help stimulate at-risk calves that are the result of dystocia (difficult birth), hypothermia from being born in the cold, or being run down from a stressful event such as disease or transport.
While “high-risk” cattle are often given high levels of hay or forage to aid in the transition to a milled diet, a study at the Arkansas Agricultural Experiment Station researches ways to increase performance.
In the past, it was believed there was no point to give injectable respiratory vaccines before about 4 months of age, because they would be inactivated by maternal antibodies. A recent study proves that’s not the case.
Elizabeth Homerosky, DVM, Veterinary Agri-Health Services, set out to find how to quickly identify compromised calves and help predict whether they can acquire optimal passive immunity. She shares what she learned here.
During periods of cold or wet weather, newborn calves (less than 2 days of age) should be checked every few hours with a thermometer and any calf with a below-normal temperature, even if it appears OK, should be warmed.
Projected value of gains for growing calves this winter are in the $1.35 to $1.40 per pound range and has the potential to go even higher based on projections for available feeder cattle numbers next spring.
Shrink is a concern because it reduces sales weight, but abnormal levels of shrink is often used as a health indicator for cattle arriving in receiving facilities at stocker operations, grow yards, and feedlots.
Trace minerals are important to calves’ development, but these nutritional components can vary in source. It turns out some trace minerals are more palatable than others, resulting in differences in consumption.
We now know the beneficial influence of feeding transition milk to calves. Is there a way to deliver that nutritional and immunological support and bypass the tedious process of harvesting and feeding transition milk?
Maternal colostrum is often considered nature’s “perfect food.” But does this “free” resource help calves achieve passive immunity as reliably as the guaranteed ingredients in a bag of colostrum replacer?
Every re-treatment puts additional stress on calves and reduces profit margins due to the additional medicine and labor costs. On the other hand, waiting too long to re-treat can increase the number of sick calves.
Spring calving brings the promise of working calves and branding season. Each operation is set up differently with varying resources to work calves. How do you minimize cattle stress during this event?
With the cost of inflation impacting every corner of a dairy, the producer’s breeding strategy has been forced to become finetuned. More and more producers are keeping just enough replacements to fill the pipeline,.
A protocol overhaul helped the team at Singing Brook Farms, Imler, Pa., up their game in colostrum delivery. Two of their key managers share how they now seamlessly deliver high-quality colostrum to every newborn calf.
It is well-known that sub-acute ruminal acidosis (SARA) is a harmful and costly condition for adult dairy cows. But when calves get SARA, is it bad news for them, too? A Canadian researcher’s conclusion: maybe not.
You should provide assistance immediately if you notice an abnormal presentation of the calf (AKA back feet, only one leg, etc.) or when there is no progress after 30 minutes for a cow or 60 minutes for a heifer.
The tick transmits Theileria orientalis to many animal species, including cattle, pigs, horses, sheep and goats. Death occurs in up to 5% of affected animals, according to Washington State University scientists.
More and more farms have made the switch from feeding calves individually to group autofed systems. However, disease detection in group-housed calves remains a challenge. Could autofeeders help detect sick calves?
