Forbs
In the context of cattle grazing, forbs are herbaceous (non-woody), broadleaf plants that are not grasses or grass-like. They can be a valuable part of a cattle's diet, providing essential nutrients, especially when grasses are less abundant or lower in quality.
Here are some common cattle grazing plants classified as forbs:
* Brassicas: This group includes several important forage forbs:
* Forage R**e (Brassica napus L.)
* Kale (Brassica oleracea L.)
* Turnips (Brassica rapa L.)
* Swedes (Brassica napus L.)
* Tyfon (a hybrid)
* Chicory (Cichorium intybus L.): Known for its deep roots which can access nutrients deeper in the soil profile and its beneficial compounds.
* Fodder Beets (Beta vulgaris ssp. vulgaris)
* Annual Kochia (Kochia scoparia L.)
* Legumes: Many legumes are classified as forbs and are highly nutritious due to their high protein content and ability to fix nitrogen in the soil. Examples include:
* Alfalfa (the most common legume used for beef cattle forage, though it requires careful management due to bloat risk)
* White Clover
* Birdsfoot Trefoil
* Kura Clover
* Sainfoin
* Purple Prairie Clover
* Cicer milkvetch
* Utah sweetvetch
* Other palatable forbs often found in pastures:
* Plantain (Plantago lanceolata): Contains beneficial compounds that can aid in fighting infections and potentially improve feed efficiency.
* Black-eyed Susan (Rudbeckia hirta)
* Lanceleaf Coreopsis (Coreopsis lanceolata)
* Showy Ticktrefoil (Desmodium canadense)
* Purple Coneflower (Echinacea purpurea)
* Cup Plant (Silphium perfoliatum)
* Oxeye Sunflower (Helopsis helianthoides)
* Lead Plant
* Stiff Goldenrod
* Wild Bergamot (Bee Balm)
* Maximilian Sunflower
* Prairie Coreopsis
* Butterfly W**d
* Wild Quinine
* Ohio Spiderwort
* Munyeroo (Portulaca oleracea)
* Tar vine (Boerhavia spp.)
* Spiny saltbush (Einadia nutans)
Important Considerations:
* Nutritional Value: Forbs generally have higher levels of crude protein, phosphorus, and digestibility, and lower levels of fiber than grasses, especially when actively growing.
* Deep Roots: Many forbs have deep root systems, which allow them to access water and nutrients from deeper in the soil, making them more drought-resistant and potentially enhancing soil structure.
* Diversity: A diverse pasture with a mix of grasses, legumes, and forbs can provide a more balanced diet for cattle, improve soil health, and offer benefits for pollinators and wildlife.
* Palatability and Toxicity: While many forbs are highly nutritious and palatable, some can be undesirable, have low palatability, or even be toxic to cattle. Proper pasture management is crucial to promote beneficial forbs and control harmful species.
