"Tips and Products for Raising Calves relating to Scours, Respiratory Diseases, Dehydration, and Nutrition"


The Calf Doctor offers specific information and products designed through years of research and field experience in raising calves. When growers receive their calves and begin with a program approach, they are able to achieve success in getting their calves off to a quantum leap start.

Following the timing of vaccinations and using the specific type of vaccines will make a big difference in the number of calves affected by scours and respiratory diseases.
The Calf Doctor has introduced a new product called Immunoboost which enhances the calves’ immune system. Handling the calves to reduce the duration of stress is key to reducing morbidity and mortality.

The Calf Doctor has developed an effective electrolyte supplement called Quantum Leap Calf-Lyte Plus. When scours and dehydration threaten the calf, use this product to quickly replenish critical electrolytes and fluids.

EPIC— Calf Scour Formula and the esophageal Danish Calf Feeder are available through the Calf Doctor.

Buy a calf that is less than a week old.

DAY ONE:  Inject 1 ml Immunoboost under the skin on the neck. Inject 5 ml of  Calf Fortifier

Feed 1 ounce (a measure) of Quantum Leap Scour Product twice daily for the first 10 days. No other meds are needed.  The Quantum Leap is aglomerized for easy mixing.

Sometime during the first week -dehorn using Dr. Larson’s Dehorning Paste.

DAY EIGHT: Inject second 1ml dose of Immunoboost.  Vaccinate with Vista Once, either inject it of squirt 2 ml up one nostril.  This covers the 5 viruses and the two bacterials Pasteurella multocida and Mannheimia haemolytica.

If lice are a problem, pour with 3 ml of Ultra Boss per 100# of body weight.  Be sure to pour every animal in the building.

Offer a grain mix of whole dry shelled corn and a protein pellet (mix should be 18% - protein) or if you have oats to feed – 1/3 corn, 1/3 oats,and 1/3 pellets.

At 3 to 4 weeks, inject BoSe or MuSe.  There  is very little selenium in whole milk.

DAY OF MOVING CALVES TO GROUP PEN: vaccinate with Vista-5

10 DAYS AFTER GROUPING: repeat the Vista-5.

Be sure to be all-in-and- all-out in whatever facility you are using. Do not mix young calves with older ones.

If Salmonella dublin is a problem, be sure to consult.  There are several ways of handling this mean bug.  It is a respiratory problem that usually strikes at 4 to 12 weeks of age.

If using electrolytes – do not put them in the milk.  Be sure to use at least as much water as the directions call for.  If they are mixed too strong they can kill the calfl!

Do not take the milk away from a scouring calf – he will starve.

Keep clean fresh water in front of the calf at all times. Make sure milk replacer has all milk proteins. Waste milk should be pasteurized.
