Effect of maize distillers dried grains with solubles and dietary enzyme supplementation on the performance of laying hens

Abstract

In an experiment on 84 Lohman Brown hens (from 26 to 68 weeks of age), the effect of the different dietary levels of maize distillers dried grains with solubles (DDGS) on laying performance and egg quality was studied. Experimental diets were isocaloric and isonitrogenous and contained 0, 5, 10, 15 or 20% DDGS. The diet with 20% DDGS was also supplemented with NSP-hydrolizing enzymes or with enzymes and additional amounts of lysine and methionine. In the first phase of the laying cycle (26-43 weeks of age) the dietary level of DDGS did not significantly affect the laying rate, daily weight of laid eggs, feed intake and feed conversion. In the second phase of the cycle (44-68 weeks of age), there were no differences in egg production parameters between groups fed diets with 0, 5, 10 and 15% DDGS. A dietary level of 20% DDGS negatively affected laying rate and daily weight of eggs, however, addition of NSP-hydrolizing enzymes to the diet reduced in part this negative influence. The level of DDGS in the diet had no effect on albumen height, Haugh units, eggshell thickness, density and breaking, or sensory properties of boiled eggs. Yolk colour score significantly increased when DDGS was included in the diet.

Use of Maize Distiller’s Dried Grains with Solubles (DDGS) in Laying Hen Diets: Trends and Advances

“…and Swiatkiwicz and Koreleski (2006) reported no significant difference in feed intake for hens fed DDGS up to 15 or 20%, respectively. Furthermore, Roberson et al (2005) pointed out that feed consumption did not influenced by levels of maize DDGS up to 15% DDGS.…”

“…In Super Nick white laying hens, Deniz et al (2013) andAbd El-Hack (2015) declared that the inclusion of 20% DDGS into diets significantly depressed egg weight and egg mass (p#0.05) compared to diets that did not contain DDGS. , Swiatkiwicz and Koreleski (2006) and Jung and Batal (2009) reported no significant differences in Haugh units, eggshell thickness or shell breaking strength between hens fed a basal diet or diets contain different inclusion levels of DDGS. Also, Cheon et al (2008) revealed no differences in weigh, strength and color of eggshell when feeding layer on 0, 10, 15 or 20% DDGS.…”

“…Also, Roberson et al (2005) suggested that egg production was not influenced by DDGS level during most periods of production. Swiatkiwicz and Koreleski (2006) studied the effect of higher inclusion rates of corn DDGS on laying hen performance. Results of phase one (26-43 week of age) showed no significant impact on egg production when Lohmann brown hens fed DDGS up to 20%.…”

“…Similarly, Roberson et al (2005) claimed that egg weight and mass did not affect by DDGS level. Contrariwise, Swiatkiwicz and Koreleski (2006) realized that daily egg weight was negatively influenced by the inclusion of DDGS in laying hen diets up to 20%. Masa'deh (2011) revealed that egg weight and mass were decreased as DDGS increased in the diet during phase I of production, meanwhile, it was not affected by DDGS levels during phase II.…”

Bones quality indices in laying hens fed diets with a high level of DDGS and supplemented with selected feed additives

“…The relatively high nutritional quality of DDGS obtained from modern ethanol technology enables the use of this feed material on a large scale in poultry nutrition, as the most effective and environmentally friendly way of using DDGS (Swiatkiewicz and Koreleski, 2008). In many earlier studies, it was concluded that DDGS was a useful feed ingredient for laying hens (Swiatkiewicz and Koreleski, 2006;Krawczyk et al, 2012;Niemiec et al, 2012Niemiec et al, , 2013. Some studies indicated, however, that the utilization of such macroelements as Ca and P decreased in poultry fed diets with high levels of DDGS (Swiatkiewicz and Koreleski, 2007;Thacker and Widyaratne, 2007;Leytem et al, 2008), which could negatively affect the mineralization and quality of bones of highly-performing laying hens.…”
