Effects of feeding Iowa-grown field peas on finishing pig performance

Abstract

The objective of this study was to investigate an alternative feedstuff, Iowa-grown field peas, for finishing pigs. Field peas (winter, spring, and summer types) grown in southeast Iowa during 2005 and 2006 were sampled and analyzed for nutrient content. Overall, the peas averaged 86% DM, 2.8% ether extract, 5.7% crude fiber, 3% ash, 19.3% CP, 1.54% lysine, 0.20% methionine, 0.18% tryptophan, and 0.74% threonine. Finishing pigs, barrows (n = 64), were randomly assigned to 16 pens with four pigs each. There were four replications per treatment group. Each pen was assigned one of the four diets. The four diets were: 1) winter pea 30% of the total diet (by weight), 2) summer pea 30%, 3) spring pea 30%, and 4) corn-soybean meal as the control. The three pea diets contained corn but no soybean meal. Each of the four diets had 0.64% lysine based on calculated analysis.

Sustitución de soja por guisante de invierno en dietas de cerdos pesados: impacto productivo del nivel de inhibidores de proteasas

“…Concretamente, en la fase de acabado no se presentaron diferencias productivas entre los animales de los cuatro tratamientos (P > 0,05). En una experiencia parecida Njoka (2008) enfrentó cuatro dietas durante la fase de acabado (80 a 123 kg), una control de soja con tres sin soja y que incorporaban un 30% de guisantes, cada una de un tipo: de invierno, de verano y de primavera. Sólo observó una tendencia en el consumo, siendo mayor en los animales alimentados con las dietas invierno y verano que con las primavera y control: 4 y 3,8 vs 3,5 y 3,4 kg, respectivamente.…”

The effect of extracted corn germ from a fractionation process on pig growth performance and carcass characteristics

“…Thus, it could be concluded that inclusion of field peas into the diet did not have a detrimental effect on carcass quality and growth performance. Njoka et al (2008) studied the effect of replacing soybean meal in the pig diet with winter, spring, and summer field peas on growth performance and carcass characteristics when compared it to a control corn-soybean meal diet. The authors indicated there were no differences in final BW, ADG, or G:F among the dietary treatments.…”

“…Despite this, pigs fed winter peas had more BF (P < 0.10) than pigs fed spring peas or the control diet. Njoka et al (2008) determined that pigs can be fed diets with Iowa-grown field peas at the 30% inclusion level, and when supplemented with synthetic amino acids, all soybean meal and a portion of corn in the grow-finish pig diet can be replaced with minimal effect on performance.…”
