Feeding Value of Field Pea and Hull-less Oat in Growing Calf Diets

Abstract

Two studies were used to evaluate the feeding value of field pea (Pisum sativum 'Trapper') and hull-less oat (Avena sativa 'Paul') in backgrounding calf diets. In the first study, dietary treatments included a control diet and two diets where a portion of the barley (Hordeum vulgare) and soybean (Glycine max) oil meal (SBM) of the control diet was replaced by either oat or pea. Average daily gain (P=.66) was not affected by dietary treatment. However, calves fed the control and pea diets had higher dry matter intakes (DMI; P<.05) than calves fed the oat diet. Subsequently, feed efficiency (gain/feed; P=.1) was improved in the calves that were fed the oat diet. In the second experiment, dietary treatments included a control diet, two diets where a portion of the control diet was replaced by either pea or oat and one diet where pea and oat were combined as a replacement. Average daily gain (P=.84) was not affected by dietary treatment. Calves consuming the control diet had higher DMI (P<.01) than diets containing either pea or oat, while the DMI of the combined diet was intermediate. Although differences were detected in intake and not in gain measurements, there was only a tendency toward differences in feed efficiency (FE; P=.17) due to dietary treatments. Field pea and hull-less oat are suitable substitutes for barley and soybean oil meal, when replacement is on an equivalent protein basis in backgrounding calf diets.

Impact — Results indicate that producers can establish a relative economic feeding value for pea and hull-less oat based upon their nutritional composition and the market price of barley and soybean meal.
Audience — Grain growers, cattle feeders, grain dealers, feed distributors, nutritional consultants and researchers.
