Managing Forage Stands in a Dry and Cool Spring
A dry, cool start to the growing season often results in slower growth of alfalfa and grass stands, as well as pastures.
Impact on Alfalfa Development
- Development may be 1–2 weeks slower than average.
- Lower yields early in the season often mean higher forage quality.
- RFV decline is slower than normal—harvest timing may be 1–2 weeks later than usual.
Harvest Timing Recommendations
- Alfalfa Hay:
- Cut based on RFV targets for your operation.
- Harvest when standing crop RFV is ~20 points higher than your target.
- Use tools like scissors clipping, PEAQ sticks, or the Growing Degree Day model (available on Manitoba Agriculture Weather Pages).
- Avoid cutting earlier than recommended—this reduces yield, depletes root reserves, and impairs second-cut growth.
- Beef producers: Cut at 10–20% bloom for optimal yield and quality.
- Dairy producers: Slightly later cutting than average can still achieve high quality with lower fiber (higher RFV).
- Grass Hay:
- Yields will be lower, but quality will be higher than in wetter years.
- Allow grasses to head out to avoid severe yield loss, even if it seems contrary to quality goals.
- Mixed Stands:
- Base timing on the major component, usually alfalfa.
- Wait until later-developing areas are ready to ensure root replenishment.
Pasture Management Strategies
- Maintain winter feeding programs well into late May and early June if possible to delay grazing
- Maintain grazing rotations to preserve forage supply.
- First grazing passes: Move quickly to clip grasses and keep them vegetative.
- After mid-summer (July–August), slow rotations as cool-season grass growth declines.
- Use flexible grazing systems (e.g., pairs with stockers) to adjust stocking rates.
- If conditions worsen:
- Sell yearlings early or move to feedlot.
- Consider early weaning to reduce cow nutritional demands.
Supplementation & Forage Shortfalls
- Supplement with protein or energy to stretch forage resources.
- Utilize lower-quality alternative feeds alongside high-quality forage.
- Feed testing is recommended to plan supplementation effectively.
