Spring calving is just around the corner, providing the promise of a new calf crop and excitement for the future. Steps taken today can set cows up for a successful calving season. However, poor preparation has a direct impact on the health and well-being of those calves as well as future reproductive performance of the herd, says Ted Perry, beef nutritionist with Purina Animal Nutrition LLC.
For an optimal calving season, Perry recommends that producers focus on three areas: body condition scores, mineral programs and the area where cows will calve. “Implementing a few strategies ahead of the calving season can make calving programs successful,” he says, adding that with today’s beef prices producers can’t afford to lose any calves.
Body condition scores
The ideal body condition score (BCS) at calving is a six, on a nine-point scale. “Being at the ideal BCS is probably the most important thing beef producers can do prior to calving,” says Perry. “It’s not hard to slip down to a body condition score of a four or five, and think it’s no big deal. But anything less than a six spells trouble.” Keeping the cows in good body condition all year can pay huge dividends on individual calf and herd performance.
Cows with low body condition scores are at risk for more calving problems. Their calves may be weaker and not as vigorous, which means they are less likely to get up and drink colostrum in the first few hours after birth.
Perry says that low BCS numbers could be a common problem this year as beef producers are trying to get through winter with low forage supplies. Fortunately, it’s not too late to increase a cow’s BCS. “Getting your body condition scores up to a six by calving will pay dividends,” he says, explaining that an adequate ration with protein, energy and mineral supplements can set cows up for a successful season.
Having a good nutrition and mineral program in place is essential for a variety of reasons, including better response to vaccinations and colostrum quality for the calf, which provides immune protection. “The ideal body condition score prior to calving coupled with a good mineral program can translate into good quality colostrum and calves that are better protected from the start,” says Perry.
He explains that, from mid-gestation to late-gestation, there will be an increase of about 20 to 25 percent for protein and mineral needs by the cow. Nutritional needs increase again as the cow gets closer to calving; increasing by more than 60 percent for minerals and 25 percent energy and protein between late gestation and calving. Meeting these nutrient requirements are critical to calf growth in-utero and the cow’s ability to care for the live calf.
