Field pea (Pisum sativum) grain is a nutrient-dense grain legume that is a palatable source of CP (25.3%), energy (1.48 NE g Mcal/kg), and other nutrients for beef cattle. Field pea grain is highly digestible, but the starch fermentation and ruminal protein degradation rates are slower than for several other common feeds. Increased DMI has been observed in some studies with the inclusion of field pea grain in the ration. Apparently field pea grain does not need to be processed for beef cows. In backgrounding and finishing rations, processing field pea grain has produced mixed results, but dry-rolling may contribute to improved animal performance. In creep feeds, 30 to 40% field pea grain (DM basis) may be optimum for animal performance. The inclusion of field pea grain in postweaning receiving rations has resulted in increased DMI. As a protein supplement for feeder cattle, field pea grain can be included at 15 to 30% of the ration (DM basis); however, growing and finishing cattle can utilize field pea grain as both a protein and energy source. Inclusion of field pea grain at a minimum of 10% of the finishing diet improved the tenderness and juiciness of beef without affecting carcass traits. Field pea grain is an excellent pellet binder. Beef cattle producers with access to field pea grain at competitive prices should consider using this grain legume in their ration formulations. |
