Abstract

Abstract Starch and fibre contribute to the energy components and add functionality to the end-product feed ingredients. An understanding of the impact of processing on carbohydrate content will support accurate formulation of feed. Six ingredients, grown or sourced in Canada, were used in this study. They included five pulses, Amarillo peas, Dun peas, chickpeas, lentils, and faba beans, and soybean meal (SBM) as a comparison. All ingredients were ground into fine or coarse products and then pelleted at one of three different temperatures. Grinding reduced the total starch (TS) content of Amarillo peas and chickpeas (P < 0.05), crude fibre (CF) in Dun peas (P < 0.05), and total dietary fibre (TDF) and insoluble fibre (IDF) in lentils (P < 0.05). Grinding only affected soluble fibre (SDF) in chickpeas. The effect of pelleting was variable for TDF across pulses. Pelleting did not affect the SDF content of pulses (P > 0.05). Finely processed SBM had higher (P < 0.05) TS, TDF, and IDF content than coarsely processed SBM. Results indicate that grinding and pelleting could affect the starch and fibre composition of some pulses.

加工对加拿大豆类淀粉和纤维组成的影响

摘要淀粉和纤维有助于能量成分，并为最终产品饲料成分添加功能。了解加工对碳水化合物含量的影响将有助于准确配制饲料。本研究使用了六种在加拿大种植或来源的成分。它们包括五种豆类、阿玛里洛豌豆、敦豌豆、鹰嘴豆、扁豆和蚕豆，以及豆粕（SBM）作为比较。所有成分都被研磨成精细或粗糙的产品，然后在三种不同温度中的一种下制成颗粒。研磨降低了Amarillo豌豆和鹰嘴豆的总淀粉（TS）含量（P<0.05）、Dun豌豆的粗纤维（CF）含量（P<0.05）、扁豆的总膳食纤维（TDF）和不溶性纤维（IDF）含量（P<0.01）。研磨只影响鹰嘴豆的可溶性纤维（SDF）。对于脉冲间的TDF，造粒的效果是可变的。制粒不影响脉冲SDF含量（P>0.05）。精加工SBM的TS、TDF和IDF含量高于粗加工SBM（P<0.05）。结果表明，研磨和制粒会影响某些豆类的淀粉和纤维组成。

期刊介绍： Published since 1957, this quarterly journal contains new research on all aspects of animal agriculture and animal products, including breeding and genetics; cellular and molecular biology; growth and development; meat science; modelling animal systems; physiology and endocrinology; ruminant nutrition; non-ruminant nutrition; and welfare, behaviour, and management. It also publishes reviews, letters to the editor, abstracts of technical papers presented at the annual meeting of the Canadian Society of Animal Science, and occasionally conference proceedings.
