How April Hay Choices Can Impact Calf Growth & Development

Overview: April’s hay choices can make or break calf growth. Learn how Timothy Grass, Alfalfa, and balanced hay mixes impact weight gain, immune strength, and early development for calves in Wyoming and Northern Colorado. Read on!

With calving season just behind us, ranchers across Laramie County, Wyoming, and Northern Colorado are shifting focus to cow recovery and calf development. Freshly calved cows need nutrient-dense feed to regain strength and produce high-quality milk, while their calves rely on digestible, protein-rich hay to support early growth and immune function.

This time of year, pastures are still rebounding, making hay selection more critical than ever. The right choice — whether it’s Alfalfa for protein, Timothy Grass for steady energy, or a balanced mix for digestion — ensures both cows and calves get the nutrients they need. On the flip side, poor-quality hay or an unbalanced diet can slow weight gain, weaken immunity, and set young livestock back.

A strong start now means healthier, more resilient calves heading into the warmer months. In this guide, we’ll break down the best hay options, key nutrients, and common feeding mistakes to help you make the most of your spring hay supply.

Why April Hay Matters for Calves

Calves experience rapid growth in their early months, requiring a steady supply of high-quality hay to meet their nutritional needs. As winter reserves dwindle and pastures aren’t yet in full swing, hay remains the backbone of a young calf’s diet. Choosing the wrong type — or failing to supplement properly — can lead to poor weight gain, weakened immunity, and long-term setbacks.

Top Hay Choices for Strong, Healthy Calves

Here’s how different hay types impact calf development in the Wyoming and Northern Colorado region:

Alfalfa: Protein-Packed Growth Booster

High in protein and calcium, making it a top choice for young calves.
Supports muscle development and immune function.
Best when balanced with lower-protein grass hay to avoid excess richness.

North Park Timothy Grass: Digestibility & Weight Gain

Highly digestible, ensuring calves absorb essential nutrients.
Lower in protein than alfalfa but still provides excellent energy.
A great starter hay for transitioning calves to solid feed.

Orchard/Brome/Timothy Mix: Balanced Nutrition

Offers a mix of fiber, protein, and energy for steady growth.
Helps prevent digestive issues in young calves.
Works well alongside grain-based feeds for a well-rounded diet.

Cow Alfalfa: Cost-Effective & Nutritious

A good mix of alfalfa and grass, providing both protein and fiber.
A solid choice for budget-conscious ranchers needing quality feed.
Helps maintain consistent weight gain without excessive richness.

Avoiding Common April Hay Pitfalls

Watch for Mold & Dust: Moisture and temperature fluctuations in spring can lead to moldy hay, which can harm calf health. Always check bales for freshness.

Balance Energy & Protein: Overloading on rich hay (like straight alfalfa) can cause digestive issues, while low-quality hay may leave calves nutritionally deficient.

Plan for Pasture Transition: With warmer months ahead, now’s the time to gradually introduce pasture grazing while maintaining a steady hay supply.
