Forage kochia is a nutritious perennial that is well adapted to the Intermountain West. There are potential advantages for beef producers to use it as a forage for grazing cows during late fall and early winter as an alternative to feeding hay. Viability and sustainability of beef production in the western U.S. can be increased if feed costs are decreased. Forage kochia could be an important management option to reduce winter feed costs and improve livestock ranching profitability.
Incorporating forage kochia into a low-quality grass diet improved nutrient utilization, increased intake and improved the rate of digestion. It also increased rate of passage and decreased retention time in the rumen thereby increasing nutrient intake. Forage kochia should be interseeded into existing grass stands to achieve a 25 to 50% proportion of the available dry matter as kochia to optimize the combination of rate and extent of diet digestion and intake.
