Abstract
There is no formal recommendation, regarding dietary concentration, when it comes to feeding distillers dried grains with solubles (DDGS) to young broilers. This study evaluated the effects of varying levels of DDGS in a diet to young broilers from 0 to 14d of age. Diets ranged from 0 to 32% DDGS concentration, with 8% increments. Increasing inclusion rate of DDGS led to decreased body weight gain (BWG), whereas mortality seemed to be linearly increased. However, there was an increase seen in feed conversion (FCR) in conjunction with the increase in DDGS in the diet. An inclusion level of 8% DDGS or less is recommended for starter diets for broiler chicks.
Highlights
When corn is fermented to be used in the production of ethanol, the bulk of the starch component of the grain is what is fermented off to make the biofuel, while the rest may become a by-product commonly known as distillers dried grains with solubles (DDGS)
Research evaluating inclusion levels of DDGS in the diet of young broilers are sparse and some have suggested that up to 25% DDGS may be included in the diet with no negative effects on body weight gain (BWG), feed conversion (FCR) or feed intake (Min et al, 2009)
The 24 and 32% DDGS treatments exhibited significantly lower BWG values compared to all other dietary treatments
Summary
When corn is fermented to be used in the production of ethanol, the bulk of the starch component of the grain is what is fermented off to make the biofuel, while the rest may become a by-product commonly known as distillers dried grains with solubles (DDGS). The researchers wished to evaluate the effects that different levels of DDGS would have on broiler chicks during the first two weeks posthatch. Other research has pointed out that the low energy density of DDGS diets may be the limiting factor in meeting the energy needs of young broilers (Wang et al, 2008).
