Study tests sprouted barley in backgrounding steers

Sprouted barley is getting a closer look as beef producers search for feed options that can hold up under drought pressure, land constraints, and volatile forage markets. In a new Animals paper, researchers evaluated sprouted barley in backgrounding diets for Angus-influenced steers, asking a straightforward question: can it replace part of a conventional ration without compromising growth or early carcass-related measures? The study used 60 steers over 60 days, comparing a control diet with rations containing 5%, 10%, or 20% sprouted barley on a dry matter basis. (pmc.ncbi.nlm.nih.gov)

That question has been building for several years. Controlled-environment sprouting systems have been promoted as a way to produce fresh forage-like feed indoors, especially where water, land, or seasonal forage availability are limiting. But the research record has been mixed, with interest often outpacing evidence. University of Minnesota reporting on sprouted fodder systems described ongoing questions around economics and feed value, while USDA-ARS has reported that sprouting can raise crude protein and fiber concentrations and slightly improve digestibility, yet still reduce dry matter yield and overall energy available from the original grain.

In the backgrounding study, steers averaged roughly 328 ± 6.59 kg at enrollment and were assigned to one of four diets, 15 animals per diet. Sprouted barley replaced corn silage and some rolled barley, and intake and feeding behavior were monitored using Vytelle bunks. The abstract indicates body weight and ruminal fluid were collected on days 0, 30, and 60, alongside carcass ultrasound measurements. A related 2023 conference abstract from the same research team reported that including sprouted barley affected dry matter intake and feeding behavior, but did not change overall body weight gain in growing steers, suggesting the main signal may be in how cattle consume the ration rather than in headline growth performance. (pmc.ncbi.nlm.nih.gov)

That pattern lines up with broader beef-feeding guidance. BeefResearch.ca summarizes multiple studies showing little difference in nutritive value, average daily gain, feed efficiency, or carcass characteristics when cattle are fed sprouted grains, though the group emphasizes that these feeds can be inconsistent and carry higher moisture, spoilage, mold, and mycotoxin risks. Those cautions matter because sprouted products can look attractive when conventional feed costs rise, but their real value depends on dry matter recovery, nutrient testing, storage logistics, and animal response in a complete ration.

The same research program has already moved beyond backgrounding. A 2026 Animal Feed Science and Technology paper from overlapping authors reported that sprouted barley in finishing diets maintained growth performance and carcass quality, while noting that economic viability remains uncertain. Another related paper in finishing Angus steers found no detectable sensory differences in beef when sprouted barley replaced part of the conventional diet. Taken together, the signal so far is that sprouted barley may be usable as a substitute ingredient in some beef systems, but it has not yet shown a clear production advantage that would overcome practical and economic hurdles on its own.

Why it matters: For veterinarians, nutritionists, and technical service teams, this is less a story about a novel feed “breakthrough” and more a story about ration flexibility. If sprouted barley can be included without depressing gain or altering carcass development during backgrounding, it could offer another option when forage supply is tight or when lower-value grain streams need a destination. But any recommendation has to be grounded in feed analysis, bunk management, and close monitoring for digestive upset, spoilage, or mycotoxin exposure. The moisture profile and variable composition of sprouted feeds make them a management issue as much as a nutrition issue. (beefresearch.ca)

There’s also an economic and systems-level angle. University and USDA sources suggest the value proposition depends heavily on seed cost, the price of the feed being replaced, and the loss in dry matter and energy that can occur during sprouting. In other words, even if animal performance is maintained, the feed may still be hard to justify unless local conditions favor it. That’s especially relevant for veterinary advisers working with beef operations under drought, feed shortage, or sustainability pressure, where “can be fed” and “should be fed” are not the same question.

What to watch: The next step is whether the full peer-reviewed paper clarifies dose-response effects on intake, rumen fermentation, and ultrasound traits, and whether future trials add the missing economic analysis producers will need before sprouted barley moves from niche interest to routine backgrounding tool.
