Colostrum reconsidered: Smaller volume of higher-quality colostrum

More may be less when it comes to colostrum feedings, as newborn calves are not necessarily able to handle large volumes of colostrum. New research shows multiple, smaller feedings may actually be more beneficial.
June 23, 2026
Liz Cox

Newborn calves have physiological limits on how much colostrum they can effectively process at one time. Successful colostrum management is not just about feeding more but about feeding the right amount in a way the calf can utilize effectively.

Calves aren’t big chicks: Know the one way egg powder helps calf raisers

Egg-derived IgY or colostrum? They are not the same. While IgYs can offer some benefits when fed daily early in life, colostrum offers calves more comprehensive protection.
September 16, 2025
Bobbi Jo Brockmann and Mark Wustenberg

Colostrum is one of Mother Nature’s most powerful and unmatched creations – the purest immunity packed with everything a calf needs to survive, thrive and grow strong. Despite what you might hear, nothing compares.

Calf scours prevention begins before birth

Twelve years ago, researchers estimated that a case of scours cost $56 per head, but that number is likely significantly lower than it should be. To minimize this, farms should focus on genetics, dry cow management, colostrum and transition milk.
April 15, 2024
Kimberly Egan

“Do you have good luck when it comes to raising calves?” That’s a question you have likely been asked, but when it comes to preventing scours and ensuring calf health, it takes more than luck!

Obstacles to successful calf raising

As more operations refine their calf programs, the negative impact protocol drift has on calf welfare, future performance and business profitability is becoming increasingly apparent.
September 14, 2023
Theresa L. Ollivett

I now view the common risk factors for disease – such as failure of passive transfer, dirty facilities and feeding equipment, cold stress and poor nutrition – as symptoms of a lack of proactive, structured monitoring programs designed to track protocol compliance as well as calf performance.

Ask a Vet: Clostridium vaccinations at dry-off for better calf passive immunity

March 15, 2021
Vicky Lauer
A Progressive Dairy reader recently asked: “Would vaccinating cows at dry-off for clostridium give passive immunity to calves to help them for the first week or so until they are vaccinated?” The simple answer is: “Yes.”
