Why Feed Deer in the Spring?

Spring feeding helps deer recover from winter, feeds antler growth from the first day of it, and supports does carrying fawns. Protein is the priority. Below: why spring is the best time to start a feeding program, and what to offer.

Spring is more than just green-up and new growth — it’s a critical reset period for your deer herd. After months of winter stress, whitetail deer enter spring needing nutrition, recovery, and support. Whether you're managing for antler size, herd health, or fawn survival, feeding deer in the spring gives you a head start on the entire season.

Why Spring Feeding Sets the Stage for the Entire Season

What happens to deer after winter?

Coming out of winter, deer are depleted. Bucks are recovering from antler drop and post-rut stress, does are entering late pregnancy, and fawns (born the previous year) are still developing. Spring is the first opportunity for deer to rebuild lost fat, regain muscle, and reestablish healthy mineral levels.

Why is spring a critical nutritional window?

From March through early June, the nutritional demands on your herd spike — but natural forage is still catching up. Supplemental feeding fills the gap by offering consistent protein, energy, and mineral access that native browse may not yet provide.

How spring feed supports herd recovery and growth

When you feed in spring, you:

Accelerate body recovery after winter
Support pregnant does and developing fawns
Jump-start antler growth with key nutrients
Establish loyalty to your property before fall

What Nutrients Do Deer Need Most in the Spring?

Do deer need protein in the spring?

Absolutely. Spring is the start of antler regrowth and fetal development, both of which require high levels of digestible protein. Bucks benefit from feeds with 16–20% protein, while does need a minimum of 14–16% to support lactation and recovery.

What minerals support antler and fawn development?

Key minerals for spring include:

Calcium & phosphorus – for antler beams and bone growth
Magnesium, zinc, copper – for tissue and immune development
Salt – to promote overall mineral uptake

These should be available via loose mineral, blocks, or feed blends starting in early spring.

Should you add fat or energy supplements in spring?

Yes — especially for does preparing to nurse. Rice bran, molasses-based pellets, and alfalfa blends provide digestible energy that helps does maintain weight and fawns thrive after birth.

Spring Feeding for Bucks: Fueling Antler Growth

When do bucks start growing antlers?

Antler regrowth typically begins shortly after bucks shed — often as early as March in warmer regions. By April, bucks are in full velvet and rapidly developing antler tissue, which is about 80% protein by composition.

How does spring protein impact velvet antlers?

Early-season protein directly influences antler potential. Bucks lacking early protein may never catch up, even if fed later. Starting strong in March/April ensures better mass, tine length, and frame size.

What’s the best feed for bucks in March, April, and May?

Look for blends with:

16–20% protein
Fortified trace minerals
Palatable textures (pellets, molasses coating, or mixed grain)

Supporting Does and Fawns Through Spring Nutrition

What should I feed does after fawning?

Lactating does need high-calorie, high-protein diets to produce nutrient-rich milk and maintain body condition. Feed with:

14–16% protein
Moderate fat (from rice bran or oilseed)
Mineral blends with copper, selenium, and phosphorus

How can I help fawns through supplemental feeding?

Even if fawns aren't hitting feeders yet, what you feed their mothers affects their:

Bone and muscle development
Immunity and disease resistance
Early survival odds

Healthy does = healthy fawns. Spring is when it all begins.

What happens if does don’t get enough nutrition in spring?

Undernourished does:

Have lower birth weights in fawns
May fail to lactate consistently
Are more likely to abandon fawns under stress

Best Feed Types for Spring Supplementation

Should I use protein pellets, mineral blocks, or both?

Use both. Pellets deliver daily nutrition, while blocks and minerals provide long-term access to trace nutrients. The combination ensures you cover energy, protein, and micronutrient needs.

Is it better to feed or plant food plots in spring?

Do both if you can. Early food plots (like clover, alfalfa, and chicory) support natural behavior, while feeders provide precise, targeted nutrition your herd can rely on when forage is sparse.

Can I use corn in the spring feed program?

Corn has low protein and limited minerals, but can be a helpful energy source when blended with protein-rich feeds or used to transition deer off winter diets. Avoid using it as a primary feed in spring.

Common Questions About Spring Deer Feeding

Is it okay to start feeding deer again in spring?

Yes — spring is a perfect time to restart feeding, especially if you backed off in late winter. Deer are actively searching for nutrition, and this is when loyalty to your site can be built.

Should you stop winter feed before switching to spring feed?

Transition slowly. Begin mixing your winter ration with spring protein blends around late February to early March. This reduces digestive shock and helps deer adjust to higher-protein content.

Can feeding in spring help retain bucks on your land?

Definitely. Bucks that associate your property with low-pressure, nutrient-rich feeding sites are far more likely to stay into the summer — and show up in the fall.

Final Thoughts: Invest in Spring, Win in the Fall

Feeding deer in the spring isn’t just helpful — it’s foundational. What you offer now directly affects:

Antler development
Fawn survival
Overall herd health

If you want stronger bucks, healthier does, and more consistent trail cam traffic, spring is the season to start smart.
