Cow Nutrition Pre- and Post-Calving Top Factor to Producing Healthy Calves

Cow nutrition during pre-calving and the 100 days post-calving is the single most important factor in producing a healthy calf.

There are many new and innovative techniques available to increase the chances of producing a healthy calf, and successfully re-breeding the cow, with nutrition at the top of the list. In my experiences working with cow-calf producers 10193-a-beef-cow-attending-to-her-newborn-calf-pv-1-248x300.jpgthroughout the United States and the world, I still see a lot of producers feeding their cows the same way that their dad did, and his dad did before him. Looking back 30 to 40 years ago, the average cow weighed 900-1,000 lbs. Today, cows average 1,200 lbs. to even up to 1,400 lbs. As cow genetics keep getting better, the nutritional needs of today’s cows and calves also need to improve to help them achieve their true genetic potential.

While there is no one-size-fits-all nutritional guide for every cow, there are general guidelines that cow-calf producers should adhere to regarding how much protein, energy, minerals and other nutrients that a cow and calf should receive to satisfy their basic nutritional needs and fulfill their genetic potential.

For example, during spring or fall calving, a cow’s body condition and genetics, available feedstuffs and even the weather are all factors to consider when determining a cow’s nutritional needs. The old saying “all a cow needs is hay, stones, bones, and salt” might still work for some, but what results can cow-calf producers expect to achieve with that kind of outdated diet?

Consider a 100-cow herd with a 90% calf crop. If 10% of the calves are born 42 days after the rest and assuming that the calves gain 2 lbs. every day, that equals 84 lbs./per calf on 10 calves at $1.00/lb. the total is $840.  While this amount doesn’t seem huge, cow-calf producers must consider the cost of maintaining 10 cows for a year that have lost their calves and won’t produce another one until next year. It costs approximately $1.50 per day to keep a cow, or $547.50 a year per cow. For 10 cows, that is a whopping $5,475 per year. The cost of maintaining healthy calves by comparison is much less than maintain cows without surviving calves.

Based on this scenario, there are 10 cows that are going to be late again (unless culled) next year, plus another 10. So, what can a cow-calf producer do to improve those numbers? A good mineral program is a must. Trace minerals are very important to a cow’s overall health, reproduction, hoof health and immune response, among other benefits. Feeding cows proteinated trace minerals 60 days pre-calving and 100 days post-calving has been proven to not only help produce a healthy, strong calf, but to also increase the onset of estrus and successful breeding.

Using a loose salt to control consumption of the minerals is recommended (reduce the amount of salt when cows are not eating enough minerals and increase the amount of salt when they are eating too much).

Supplementing some type of protein will help the cows digest poorer quality forages better. Protein tubs, blocks, DDGs or protein pellets are recommended, but producers will need to ensure that the protein is readily available and consumption can be controlled.

Forages are the main component in a cow’s diet. A 1,200 lb. cow requires about 25-35 lbs. of dry matter per day. Producers are encouraged to have their forages...
