Nutritional value of diets containing graded levels of wheat distillers grains with solubles fed to broiler chicks

Abstract

This feeding trial was conducted to determine the effects of graded levels of wheat distillers dried grains with solubles (DDGS) on nutrient digestibility and performance when fed to broiler chicks. A total of 125, day-old, male broiler chicks (52.8 ± 0.6 g) were fed wheat/soybean meal-based diets containing 0, 5, 10, 15 or 20% wheat DDGS. There were five birds per pen and five replicate pens per treatment. Digestibility coefficients for dry matter (P = 0.001), energy (P = 0.001) and phosphorus (P = 0.001) declined in a linear manner with increasing levels of wheat DDGS in the diet. Despite the lower digestibility of nutrients in diets containing wheat DDGS, there were no significant differences in weight gain (P = 0.721), feed intake (P = 0.748) or feed conversion (P = 0.766) due to the incorporation of wheat DDGS in the diet, although weight gain and feed conversion showed a tendency to decline at the highest inclusion level (20%) in the diet. The overall results of this study indicate that wheat DDGS can be successfully incorporated into diets fed to broiler chicks. Potential detrimental factors contained in wheat DDGS, including a low energy and low lysine content, can be compensated for in diet formulation. Therefore, when the price of alternative feed ingredients dictates, wheat DDGS can be incorporated into diets at levels as high as 15% without detrimental effects on broiler performance.

Effect of graded levels of wheat-based dried distillers’ grains with solubles on performance and carcass characteristics of feedlot steers

“…This value is somewhat lower than that reported by Boila and Ingalls (1994a); average 40.793.1%) for wheat-based DDGS, but similar to that (35.7%) reported by Thacker and Widyaratne (2007). Spiehs et al (2002) reported 30.29 6.4% CP for corn-based DDGS, while Kleinschmit et al (2007) reported an average CP value of 32.1%.…”

Application of dried distillers grains with solubles (DDGS) as a replacer of soybean meal in broiler chickens feeding

“…The chickens administered the mixtures with 10 % addition of DDGS, were characterised by deteriorated body weight gains and feed conversion ratio. Thacker & Widyaratne (2007) applied feed mixtures with different levels of wheat DDGS (0, 5, 10, 15 and 20 %) in chicken feeding. They showed that DDGS addition to feed (15 %) did not affect the production results.…”

“…These products are constituted by components from initial raw material, being insensitive to fermentation (non-starch carbohydrates, protein, fat, ash and others), and biomass of the multiplied yeasts. Dried grains of cereal distillers are rich in protein, exogenous amino acids, B-group vitamins, biotin and mineral compounds, including phosphorus (Koreleski & Świątkiewicz 2006, Thacker & Widyaratne 2007, Min et al 2008. The process of yeast fermentation results in the synthesis of microbiological phytase and, therefore, the availability of phosphorus in the discussed products is considerably greater than in other vegetal feeds (Martinez Amezcua et al 2004, Lumpkins & Batal 2005.…”

“…In many countries, including Poland, investigations have been conducted on the possibility of applying DDGS in feed mixtures for various animal species, including broiler chickens (Nyachoti et al 2005, Świątkiewicz & Koreleski 2007, Thacker & Widyaratne 2007, Wang et al 2007, Świątkiewicz & Koreleski 2008. Results of the studies indicate that a part of soybean meal in a feed mixture may be replaced by DDGS without lowering production results.…”
