“…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.…”

An experiment with 192 caged ISA Brown laying hens, fed a diet containing a high level of corn distillers dried grains with solubles (DDGS), was conducted to determine the influence of selected feed additives on biomechanical and geometrical indices of tibia and femur bones. At 26 weeks of age hens were randomly assigned to 8 treatments with 12 replicates (cages of two hens). To week 55, hens were fed isocaloric and isonitrogenous experimental diets either containing or not containing a high level of DDGS (200 g/kg). The diet containing 200 g/kg of DDGS was supplemented or not supplemented with feed additives, i.e. enzymes (xylanase and phytase), sodium butyrate, probiotic bacteria (L. salivarius), herbal extract mixtures (Taraxaci siccum, Urticae siccum, and Salviae siccum), inulin or chitosan. At week 55, inclusion of DDGS in the diet had no effect on biomechemical (bone breaking strength, yielding load, and stiffness) or geometrical (cortex thickness, cross-section area, weight, and length) indices of tibia and femur bones (P > 0.05). Some of the supplements used had a beneficial effect on bone quality in hens fed the diet with a high level of DDGS. Thus, the addition of probiotic bacteria or herb extracts increased the breaking strength of femurs and breaking strength and yielding load of tibias (P < 0.05). The results of this study indicate that DDGS may be included to a level of 20% in the diet of laying hens without any negative influence on bone quality, while such feed additives as probiotic bacteria and herbal extracts may improve the selected biomechanical indices of bone quality of layers fed diets with a high level of DDGS.

The aim of the study was to determine the effect of three different phyto-humic feed preparations on the basic qualitative characteristics of eggs, i.e. total cholesterol content and fatty acid profile of the yolk. The study was carried out on 80 Lohmann Brown (LB) laying hens in an experimental facility with a floor maintenance system on a straw bedding (5 layers/m2). A control group (K) and three experimental ones (A, B, C), with 20 birds in each (in separate pens), were created. The birds were placed in the 16th week of life, while the experimental preparations were introduced in the 22nd week of life and were administered for 43 weeks (constant 3% addition to the feed mixture).The following preparations were applied: humic-peat (H-t) in group A, humic-herbal (H-z) in group B, and humic-lucerne (H-1) in group C. The eggs for the study were collected three times, 30 eggs from each group in the following periods: 1st series – 31st week of life (peak of laying period); 2nd series – 54th week of life (later phase of laying period) and 3rd series – 65th week of life (final phase of laying period). Six samples (mean of 5 well-mixed yolks) from each group in three laying periods (360 eggs were used in total) were prepared for laboratory analyzes (lipids examination). Laboratory analyzes were performed using a chromatograph – Finnigan Focus PolarisQ manufactured by Thermo Electron with capillary columns: HP-88 by Agilent J&W (fatty acids) and Rtx-1MS by Restek (cholesterol). The applied phytohumic preparations – but only those with a share of dried lucerne or herbs – significantly (p ≤ 0.05) reduced total cholesterol content, especially in group C (10.88 mg/g yolk) compared to group K (11.94 mg/g yolk). All preparations positively influenced the fatty acids profile of yolk; there was a significant (p ≤ 0.05) increase in the concentration of n-3 PUFAs (max 2.84% in the group B), the n-6/n-3 ratio decreased significantly (most beneficial 8.33 in group B), and lipids quality improved: atherogenic index (AI) decreased significantly (p ≤ 0.05) in group A (0.32) and thrombogenic index (TI) was a significantly (p ≤ 0.05) lower in all experimental groups (0.83 – 0.84) compared to group K (0.36 and 0.87 respectively). Dietary phyto-humic preparations increased the nutritional and dietary value of hen eggs.

“…Hen eggs are an important component of the human diet. Their physico-chemical and biological properties are quite well known, and in recent years their role as a source of nutraceutical and biomedical substances has increased [ 1 , 2 , 3 , 4 ]. In addition to protein, fats (fatty acids), enzymes and vitamins, egg albumen and yolk also contains minerals (macroelements, microelements, trace elements) [ 5 , 6 , 7 , 8 , 9 ].…”

This study was conducted to determine the effect of dietary supplementation with two humic preparations, Humokarbowit (HKW) and Humobentofet (HBF), on the mineral content of the albumen and egg yolk of Lohmann Brown hens. The content of macroelements (Ca, K, Mg, Na, P, S), microelements (Al, Ba, Cu, Fe, I, Mn, Si, Sr, Zn) and trace elements (Ag, As, Be, Bi, Cd, Co, Cr, Ga, Hg, Li, Mo, Ni, Pb, Rb, Sb, Se, Sn, Ti, Tl, V, W, Y and Zr) in the feed mixture (FM), albumen and yolk were presented. The material was collected from laying hens kept in a cage system in two groups, control (C) and enriched (E), with standard feed and feed enriched with humic preparations, respectively. The enriched feed mixture was characterised by a significantly higher Ag, Ba, Be, Bi, Co, Fe, Ga, Hg, K, Mg, Ni, S, Sb, Si, Zn and Zr content compared to the standard, basal mixture. Only some of these elements were found in significantly increased levels in albumen (Bi, Co, Ni, S) and yolk (Bi, Fe, K, Sb). Another noteworthy finding was a significantly lower concentration of Na in the content of eggs from the E-Group, which corresponds to the content of this important macronutrient in the feed. In addition, a significant increase in the concentration of elements such as Al, I, Li, Sr, Ti, Tl, Y, W was noted with a reduction in Cd, Cr, Hg, Mn, Rb, Sn in Group-E, which indicates a complicated egg formation processes, including biotransfer-essential and non-essential chemical elements.
