Anyone who dairy farms knows raising calves is a big investment. Feed and labor costs are high, and it can take more than two years before a calf starts contributing to the bulk tank as a cow.

Despite this, it still makes sense to invest in your calves up front. Feeding higher volumes of milk replacer and a program with quality starter and grower can deliver immediate and long-term results.

Short-term gains

Your future profits depend on your calves’ growth and development today. A diet of milk replacer, starter and grower that delivers the right amount of nutrients at every stage is essential for their performance as a calf, and their future productivity as a cow.

Feeding a full potential diet through six months of age can help calves achieve:

  • 50 percent more rumen surface area[1]
  • 46 pounds of weight gain and 1 inch of height growth[2]
  • 13.8 percent increase in average daily gain[3]

But it’s not just about the gains on the scale. Feeding a full potential diet can support gut and immune health, allowing calves to better withstand disease challenges.[4],[5]

Long-term results

Proper development, including weight gain, height, rumen papillae and mammary tissue, at the beginning of a calf’s life translate to more production as cows once they enter the milking herd. Research showed calves fed a full potential nutrition program through six months of age can achieve as much as 6,588 pounds more milk per cow through three lactations.[6]

For every 100 milking cows, the additional pounds of milk could lead to more than $98,000 in additional milk income over three lactations (at $15.00/cwt). The extra milk income can deliver a 5:1 return on your calf nutrition investment through three lactations.[7]

Program for productivity

Capitalize on these results by providing a full potential milk replacer at a rate of 2.5 pounds of dry matter per calf per day for the first eight weeks of life with a free-choice 22 percent starter. Continue feeding starter ad-lib through 12 weeks of age. Then, transition calves to an 18 percent grower at a rate of 10 pounds per head per day with free-choice hay.

Using a milk replacer, starter and grower designed to work together with similar ingredients can help establish feed preference to keep calves eating during diet transitions. Easier transitions help maximize intakes, improve growth and can help reduce age-at-first-calving by up to two months.[1]

However you crunch the numbers, investing in calf nutrition pays off. The gains you achieve today helps set them up for long-term performance. Contact your calf and heifer specialist to see the results for yourself.
