What Are Alternative Feeds — and Why They Matter for Dairy Producers

100

Rising feed costs and unpredictable weather have many dairy producers rethinking their feed and cropping strategies. One growing trend is the use of alternative feeds — crops that fall outside the traditional corn and alfalfa rotation. These options can stretch feed inventories, support herd health, and make dairy operations more resilient.

Defining Alternative Feeds

Alternative feeds are non-traditional crops used to supplement or partially replace conventional forages. They might be double-cropped between main harvests, grown as cover crops, or planted on land less suited to corn or alfalfa.

Each farm defines “alternative” differently. For some, it might include small-grain silages or clovers. For others, it could be sorghum, triticale, or field peas. The goal is the same — diversify the forage base to reduce risk, manage costs, and protect soil health.

Legumes: High Protein and Soil Benefits

Legumes such as clover, field peas, and birdsfoot trefoil offer strong protein levels and valuable soil benefits.

  • Clover can contain over 25% protein and helps fix nitrogen in the soil. Mixing clover with grasses reduces bloat risk and keeps pastures balanced.

  • Field peas grow well in cool seasons and supply both protein and energy. Their residues decompose quickly, adding nutrients back to the soil.

  • Birdsfoot trefoil thrives in wet soils, offers good digestibility, and doesn’t cause bloat. It produces natural tannins that improve protein use, though it needs careful management during establishment.

In general, legumes improve soil fertility and reduce the need for purchased protein supplements such as soybean meal.

Grasses: Heat-Tolerant and Productive

Warm-season grasses are another popular choice among producers.

  • BMR sorghum hybrids are highly digestible, rich in energy, and perform well in hot, dry weather. Some newer types can produce milk yields close to corn silage while requiring fewer inputs.

  • Sudangrass and sorghum-sudangrass crosses (Sudex) grow fast and tolerate drought. They work well as emergency forages, but grazing should wait until plants reach 18–24 inches to prevent prussic acid poisoning.

  • Triticale, a wheat-rye hybrid, is versatile and can be used as silage, grain, or cover crop. It holds its protein and energy longer than many small grains and helps protect soil over winter.

These crops help balance feed inventories and add flexibility to crop rotations.

Practical Benefits on the Farm

Alternative feeds provide nutritional, agronomic, and economic benefits. They help producers extend feed supplies, improve soil structure, and reduce input costs. For farms focused on sustainability, crops like clover and triticale also capture nutrients, protect against erosion, and boost soil health.

From a feeding perspective, a mix of forages can improve rumen function and feed efficiency. Better fiber digestibility means more milk per pound of feed. Combining legumes and grasses helps balance protein and energy throughout the year.

Managing for Success

Alternative feeds should complement, not replace, conventional forages. Each crop has its own nutrient profile, yield potential, and management needs. Working closely with a nutritionist ensures the ration remains balanced for milk production and cow health. Planning ahead also helps identify where these crops fit best in your rotation and feeding system.

A Tool for Flexibility

Alternative feeds offer flexibility in challenging years and opportunity in good ones. They can help producers manage feed shortages, lower costs, and build more sustainable systems. Most importantly, they allow farms to adapt to changing weather and market conditions without compromising performance.

As more producers explore new forage options, alternative feeds are proving to be more than a temporary fix — they’re becoming a cornerstone of modern, efficient, and resilient dairy production.
