“…There is also no previous study on the effect of synbiotics on the fatty acid composition of egg yolk. The fatty acid composition of eggs depends on the composition of the diet, the bird's digestive system, and the biosynthetic processes of the laying hens (Popeila and others ). Table to show the effects of the 4 dietary treatments on the fatty acid composition of egg yolk from hens at 24, 28, 32, and 36 wk of age.…”

A 16-wk feeding experiment was conducted to investigate the effects of a prebiotic, isomaltooligosaccharide (IMO), a probiotic, PrimaLac®, and their combination as a synbiotic on the chemical compositions of egg yolks and the egg quality of laying hens. One hundred and sixty 16-wk-old Hisex Brown pullets were randomly assigned to 4 dietary treatments: (i) basal diet (control), (ii) basal diet + 1% IMO (PRE), (iii) basal diet + 0.1% PrimaLac® (PRO), and (iv) basal diet + 1% IMO + 0.1% PrimaLac® (SYN). PRE, PRO, or SYN supplementation not only significantly (P < 0.05) decreased the egg yolk cholesterol (24- and 28-wk-old) and total saturated fatty acids (SFA; 28-, 32-, and 36-wk-old), but also significantly (P < 0.05) increased total unsaturated fatty acids (UFA; 28-, 32-, and 36-wk-old), total omega 6 and polyunsaturated fatty acids (PUFA), including linoleic and alpha-linolenic acid levels in the eggs (28-wk-old). However, the total lipids, carotenoids, and tocopherols in the egg yolks were similar among all dietary treatments in the 24-, 28-, 32-, and 36-wk-old hens. Egg quality (Haugh unit, relative weights of the albumen and yolk, specific gravity, shell thickness, and yolk color) was not affected by PRE, PRO, or SYN supplementation. The results indicate that supplementations with IMO and PrimaLac® alone or in combination as a synbiotic might be useful for improving the cholesterol content and modifying the fatty acid compositions of egg yolk without affecting the quality of eggs from laying hens between 24 and 36 wk of age.

The aim of the study was to evaluate the effect of Chinese herbal mixture (CHM) in laying hen diets on performance, egg quality and egg nutrition components, as well as selected blood biochemical parameters. A total of 270 Lohmann Brown laying hens, 24 week of age, were randomly distributed into three dietary treatments and fed for 6 week. The CHM was used at the levels of 0%, 0.5% and 1.0% in the diets of the control and two treatment groups respectively. Each dietary treatment was divided into five replicates, comprising of 18 hens each. Hens were housed in a 3-tier battery system. Feed and water were provided ad libitum. Blood samples and eggs were collected at the end of the experiment. The results showed that dietary treatments did not affect egg weight, mortality, eggshell thickness, albumen height, Haugh units, eggshell-breaking strength and egg-shape index. Dietary supplementation of CHM significantly improved (p < 0.05) laying rate and the lowest feed conversion ratio were observed with 1.0% CHM supplementation diets. CHM supplementation decreased (p < 0.05) cracked-egg rate, egg yolk cholesterol, blood serum levels of cholesterol, triglyceride, low-density lipoprotein cholesterol (LDL-C) and alanine aminotransferase (ALT) and increased blood serum levels of high-density lipoprotein cholesterol (HDL-C). No differences in serum total protein, serum albumen, serum glucose and aspartate amino transferase (AST) were observed in hens fed CHM. In conclusion, dietary supplementation with CHM improved egg production and egg quality and reduced serum cholesterol concentrations in laying hens. Dietary supplementation of 1.0% CHM in layer diets may be a feasible means of producing eggs with lower cholesterol and higher egg yolk phospholipid contents for health conscious consumers.

“…The highest TP values were noted in laying period final phase, which probably resulted from decreased demand on egg white production, and thus growth was noted in TP concentration in blood serum in all the groups. Popiela et al (2013) revealed no TP concentration changes in LB hens (40.52-42.43 g/l) in case of different mixtures composition but with similar energy, protein and mineral components level. The results obtained suggest absence of an effect of applied feed additives (herbs, lucerne, humic raw materials) on TP concentration in blood serum.…”

“…Similar values were provided by Suchý et al (2004), who noted TCh concentration in the range of 3.13-5.80 mmol/l in laying hens aged 25-50 wks, while Nobakht et al (2012) in older Hy-line laying hens (62-74 wks-old) observed the range of 3.58-7.63 mmol/l depending on herbs dose in a diet. This results from the fact that high requirements on TCh essential for yolk substance formation occurs in a period of intense laying production, which may lead to a decrease in this parameter level in blood serum of laying hens (Pavlik et al 2007, Popiela et al 2013. Also triacylglycerols (TAG) concentration was not affected by hens diet.…”

An influence of various humic-plant feed additives based on some herbs (nettle, chamomile, yarrow, perforatum), lucerne and humic materials on biochemical indices of Lohmann Brown (LB) layers blood plasma was estimated. Hens were housed in deep litter system, 20 birds in a group. Four groups were formed: control (C -standard feeding), and experimental, supplemented with preparations: E-1 herbal-humic, E-2 humic-herbal and E-3 -humic-lucerne. Hens were placed in the pens on the 16 th week of life, addition of preparations with standard food mixture started at the 22 nd wk and lasted until 66 th wk of life. Blood for analyses was collected four times in the following periods: 27, 37, 54 and 65 th wk of life. The applied humic-plant preparations to a limited degree affected the values of examined biochemical parameters in serum: total protein (TP), albumins (Albs), glucose (Glu), urea, triacylglycerols (TAG), total cholesterol (TCh), alanine aminotransferase (ALT), aspartate aminotransferase (AST) and alkaline phosphatase (ALP). It is difficult to determine based on these study, which preparation is one the most active biologically, however is seems that humic-lucerne preparation affected the examined blood parameters to the highest degree. The reference values ranges in hens blood serum LB hens were proposed for: TP (43-65 g/l), Albs (15-22 g/l), urea (0.5-1.2 mmol/l),
