When it comes to first-calf heifers, nutrition matters big time.
“These new moms have incredibly high nutrient requirements,” says Kirk Ramsey, veterinarian with Neogen. “Not only are they still growing, but lactation takes it to a whole new level.”
Ramsey suggests separating and supplementing them away from the mature cows in order to meet those demands.
In addition, body condition score is key.
“Heifers with a body condition score of six at calving are way more likely to breed back on time,” Ramsey says. “Let’s make sure to be tracking that.”
Early breeding season is also a win-win, according to Ramsey.
“Start the season earlier for heifers,” he says. “Heifers bred within 21 days of the first breeding cycle are more likely to breed back. They’re going to wean heavier calves, and it’s even shown that they’re going to last longer in our herd.”
Lastly, producers should address energy demands as early as possible.
“Energy requirements at calving skyrocket almost immediately, and compensating for poor condition after calving is nearly impossible,” he says. “Focus on the last months prior to calving to make any condition adjustments that you need to. By nailing these couple points, we boost their breeding success, leading to a healthier herd, heavier calves, and a more profitable operation.”
