When should I start to introduce calf starter to my bottle calves?

We suggest offering a good quality starter within the first 3 days of birth. Offering small amounts of starter early on will allow your calves to find and introduce themselves to starter intakes sooner. Always offer free choice water.

How much milk replacer should I be feeding my calves?

Mercer Landmark offers many different milk replacer and calf programs. Every farm is different and our calf and heifer specialists work with each operation to help you determine your growth goals and how to reach them.

Should I be feeding probiotics?

Maintaining a healthy gut is always important in every calf, but all probiotics are not the same. While some probiotics are more calf specific then others, we encourage you to work with your feed specialist to help maintain a healthy gut environment in your calves.

Can I make up for a lower ADG during the milk phase by feeding more during the grower phase?

This is called compensatory gain, and the answer is no. While it may cost less to put weight on an animal as he or she gets older, you lose the efficiency as a young animal and you cannot make up for the lost gain opportunities at a young age during the grower stage or beyond.

At what age should I be weaning my calves?

Most commonly dairy replacement heifers are kept on milk for 7 to 8 weeks, where dairy bull calves may be weaned a week earlier around 6-7 weeks. Weaning can vary on each farm depending on your current program and growth goals.

Is there a way I can utilize my whole milk on farm?

Yes, in addition to milk replacer we offer a balancer product that can boost your whole milk to help your calves put on both frame growth and weight to get your calves off to a better start, while still being able to use on farm milk.  Talk with one of Mercer Landmark’s calf and heifer specialists to build a plan that gives your calves a balanced nutrition program.

Does Mercer Landmark offer a nutrition program for automated calf feeders?

Yes, Mercer Landmark’s calf and heifer specialists can work with you to come up with a feeding program individualized to your farm and growth goals.
