Nutritional quality of eggs from hens fed distillers dried grains with solubles

Abstract

A feeding trial was conducted with laying hens where either 10% or 20% regular-fat distiller's dried grains with solubles (R-DDGS) or low-fat DDGS (L-DDGS) were incorporated into the feed. Production parameters and the effect of DDGS on egg nutritional quality, focusing on yolk lipids, were evaluated. Neither R-DDGS nor L-DDGS at up to 20% of laying hen feeds had a statistically significant impact on hen weight gain, egg production, feed intake, feed efficiency, egg mass, or egg weight. Specific gravity was slightly lower for eggs from hens fed 10% R-DDGS or 20% L-DDGS. Eggs from layers fed DDGS had enhanced levels of tocopherols, tocotrienols, and xanthophylls in the yolk, as well as also increased yolk yellow and red color. Eggs from L-DDGS diet had higher tocopherol content, but eggs from R-DDGS diets had higher xanthophylls. Fatty acid composition in eggs was slightly altered by DDGS, but the ratio of saturated to unsaturated fatty acids was very similar. Feeding DDGS to layer hens had no effect on lecithin or cholesterol content of the eggs. Thus, inclusion of DDGS in the diet of laying hens resulted in increases of several beneficial lipophilic nutrients in egg yolks with no apparent detrimental effects.

Peptide supplementation to nutrient‐adequate diets enhanced internal egg quality during storage in hens at peak production

“…There were effects of peptide supplementation on internal quality of eggs without, as previously noted, any effect on production. A similar observation had been made in other studies . It was observed that effects of peptide supplementation on internal quality of eggs were mainly observed after 8 weeks of feeding the experimental diets.…”

Growth performance, carcass characteristics, meat and egg quality, and intestinal microbiota in Beijing-you chicken on diets with inclusion of fresh chicory forage

“…Yolk was separated from albumen to determine yolk weight. Yolk and albumen samples were dried using a freeze dryer (Modulyod-230, Thermo Fisher Scientific Inc., MA) and then ground for protein, lecithin and cholesterol determination (Trupia et al 2016;Liu et al 2018b).…”

Feeding Value of Distillers Dried Grain with Soluble for Poultry

“…Hassan and Aqil (2015) reported DDGS can safely be added at the level of 10% without affecting growth performance of broiler chicks from 0 to 35 days and 20% without affecting productive performance in laying hen from 30 to 42 weeks of age. Trupia et al, (2016) reported that regular and low-fat DDGS addition up to 20% to layer diets did not influence egg production and egg weight. Gacche et al, (2016) reported that DDGS can be incorporated in broiler feed up to 20% in replacement of soybean meal without affecting the performance but DDGS at 30 % level adversely affected the performance of the broilers in terms of weight gain.…”

“…Hack et al, (2015) reported DDGS substitution level more than 75% decreased (P≤0.01) values of feed intake in brown laying hen. Trupia et al, (2016) reported that regular and low-fat DDGS addition up to 20% to layer diets did not influence feed intake. Gacche et al, (2016) reported that DDGS at 30 % level adversely affected the feed intake.…”
