Protect Every Newborn Calf from Scours

Protect Every Newborn Calf from Scours

Newborn calves are vulnerable to health issues, like scours, without proper colostrum intake within 2-4 hours of birth. Ensure every calf nurses quickly for maximum colostrum consumption with Start Strong® for Calves!

Start Strong® for Calves

Within 12 hours, calves lose 50% of their ability to absorb antibodies from colostrum.1 That’s why we developed Start Strong for Calves.

This natural oral drench stimulates appetite, enhances gut health, boosts immunity and provides newborns with the energy they require to get up and receive colostrum fast!

Start Strong comes in convenient packaging with an easy-to-use pump.

  • Turn upside down and administer orally 10 ml (1 pump = 5 ml) within 12 hours of birth.
  • Repeat for 1–2 days if the calf is not energetic.

Product# 2500-250 // Product# 2500-60
Available in 250 ml and 60 ml bottles
25 treatments per 250 ml bottle

How it Works

Start Strong uses a unique dual-action approach to provide much-needed energy to newborn calves.

  • First, a complex energy source made up of highly absorbable fats that are easily broken down for a quick boost of energy.
  • Second, bioactives help stimulate a calf’s appetite to get them up and nursing while strengthening immunity and promoting a mature and developing gut.

Without colostrum protection, calves are at an increased risk of developing scours and 74 times more likely to die in the first 21 days of life.2

This product does not replace colostrum, but helps animals consume it quickly. It has immune-stimulating properties, but not passive antibody transfer.

Dosing Start Strong 30 minutes to 1 hour before a calf that’s going to nurse or consume colostrum from a bottle is recommended to help build vigor and encourage better voluntary consumption. If it’s a calf that will be tubed and manually provided colostrum, wait closer to the time you expect the calf to voluntarily consume milk or milk replacer.

Start Strong is an oral drench. Simply turn the bottle upside down and provide two pumps directly into the back of the mouth.

The same applicator can be used on multiple animals. Just wipe the Start Strong bottle clean and reuse it on healthy animals. If it’s used on a sick animal, wipe it down with a disinfectant before using it again.

A 250 ml bottle contains 25 treatments.

It’s nice to know that when I have a calf down and out, I can give them Start Strong and walk away knowing that the next time I see him, he’s going to be up and nursing.

We calve in early February in Montana, and it’s been below zero for long stretches at a time. This has helped every one of our chilled calves get up and want to nurse. A neighbor told us to try it and I’m glad he did! We won’t be without it again. Very cost-effective also!

I started using this product last year on both my calves and lambs. I won't go through another calving and lambing season without it. When I was lambing, it was between -4 and -11 in the barn and the lamb warmed right up without any problems. I even loaned a bottle to a neighbor who was having trouble with twin calves, he won't be without it next year.

I want you to know, we have a beautiful bull calf, but mom rejected him. I gave him Start Strong and he got up and drank a pint of colostrum replacement.

We bottle-raise feedlot calves. I used Start Strong on one of them and the calf was up and sucking in an hour! Never had one that responsive. I’ll continue to use it and recommend it to others. Well done guys!
