High-energy diets deliver real returns during Canadian calving season
Canadian cattle producers facing another tough calving season now have solid numbers showing why investing in high-energy diets pays off. New research confirms that maintaining proper body condition scores between 5-6 through strategic feeding can boost weaning weights by 25 kilograms per calf.
With feed costs still elevated across most provinces, many producers have been questioning whether premium nutrition during calving is worth the expense. The data suggests it absolutely is – that extra 25 kg at weaning translates to significant revenue when multiplied across your entire calf crop.
The timing couldn't be better for Canadian producers. Most operations are entering their peak calving period, and winter conditions across the Prairie provinces and eastern Canada are testing cattle harder than usual. Proper nutrition now sets the stage for the entire production year.
What this means for your operation
If your cows aren't hitting that BCS 5-6 range right now, you've got a narrow window to make adjustments that will pay dividends at weaning time. This isn't about pushing cows to excessive condition – it's about hitting that sweet spot where metabolic demands are met without waste.
Practically speaking, this means evaluating your current ration and potentially upgrading energy density through quality hay, grain supplements, or energy-dense byproducts. The investment in feed quality during the next 60-90 days will determine whether you're leaving money on the table come fall.
For operations running tight margins, focus your premium feeds on first-calf heifers and older cows first. These animals face the highest metabolic stress and show the biggest response to improved nutrition. Your middle-aged cow herd may maintain acceptable performance on slightly lower energy rations.
Key numbers
• Target body condition score: 5-6 on the 9-point scale during calving
• Potential weaning weight increase: 25 kg per calf with proper nutrition
• Critical feeding window: 60-90 days around calving for maximum impact
• Highest priority animals: first-calf heifers and cows over 8 years old
• Expected return on investment: varies by current feed costs and fall calf prices
What to watch next
As calving season progresses, monitor your cows' body condition weekly rather than just at the start. Weather conditions across Canada remain unpredictable, and extended cold snaps can quickly erode body condition even on good rations. If conditions deteriorate, be prepared to adjust energy levels upward.

Frequently asked questions
Q: How do I know if my cows are at BCS 5-6 during calving season?
A: Cows at BCS 5-6 should have slight fat cover over the ribs that requires firm pressure to feel, with some fat around the tailhead. You should not see individual ribs or hip bones prominently.
Q: Is the 25 kg weaning weight increase worth the extra feed cost?
A: At current calf prices averaging $3.00-3.50 per pound, that extra 25 kg (55 lbs) represents $165-190 additional revenue per calf, typically covering the additional feed investment with profit remaining.
