Abstract

BackgroundPost-production fractionation of wheat distillers grains with solubles (DDGS) increases their crude protein content and reduces their fiber content. This experiment was conducted to determine the effects of fractionation of wheat DDGS on apparent total tract digestibility (ATTD) and performance when fed to broiler chicks (0–21 d).MethodsA total of 150, day-old, male broiler chicks (Ross-308 line; Lilydale Hatchery, Wynyard, Saskatchewan) weighing an average of 49.6 ± 0.8 g were assigned to one of five dietary treatments in a completely randomized design. The control diet was based on wheat and soybean meal and contained 20% regular wheat DDGS. The experimental diets contained 5, 10, 15 or 20% fractionated wheat DDGS added at the expense of regular wheat DDGS.ResultsThe ATTD of dry matter and gross energy were linearly increased (P < 0.01) as the level of fractionated wheat DDGS in the diet increased. Nitrogen retention was unaffected by level of fractionated wheat DDGS (P > 0.05). Weight gain increased linearly (P = 0.05) as the level of fractionated wheat DDGS in the diet increased. Feed intake, feed conversion and mortality were unaffected by level of fractionated wheat DDGS in the diet (P > 0.05).ConclusionsPost-production fractionation of wheat DDGS improves their nutritional value by lowering their fiber content and increasing their content of crude protein and energy. These changes in chemical composition supported increased weight gain of broilers fed wheat DDGS.

Highlights

Post-production fractionation of wheat distillers grains with solubles (DDGS) increases their crude protein content and reduces their fiber content
Production of fractionated wheat distillers grains with solubles The process used to produce fractionated wheat DDGS has been described by Zhang et al [11]
The chemical analyses for the wheat and soybean meal used in the present experiment are within the range of those previously reported for these ingredients in standard industry sources such as Feedstuffs [21], the Novus Raw Material Compendium [22] as well as the National Research Council’s Feed Composition Tables [13]

Summary

Introduction

Post-production fractionation of wheat distillers grains with solubles (DDGS) increases their crude protein content and reduces their fiber content. This experiment was conducted to determine the effects of fractionation of wheat DDGS on apparent total tract digestibility (ATTD) and performance when fed to broiler chicks (0–21 d). The experimental diets contained 5, 10, 15 or 20% fractionated wheat DDGS added at the expense of regular wheat DDGS. There is increasing interest in producing ethanol from cereal grains for use in motor fuel [1]. Ethanol-blended fuels offer several advantages over regular gasoline including protection from gas line freezing and higher octane ratings [2].
