Influence of sumac (Rhus Coriaria L.) and ginger (Zingiber officinale) on egg yolk fatty acid, cholesterol and blood parameters in laying hens

Abstract

The aim of the study was to evaluate the potential effect of different levels of sumac (Rhus coriaria L.) seed powder and ginger (Zingiber officinale) root powder on egg yolk fatty acid composition, blood/yolk cholesterol in laying hen. A total of 63 (ATAK-S: Domestic Turkish Laying Hens) laying hens (average weight: 1470 g each hen, 25-weeks of age) were assigned to seven treatment diets including sumac seed (S) and ginger root powder (G) at 0 g/kg (control), 10 g/kg (S1), 20 g/kg (S2), and 30 g/kg (S3); 10 g/kg (G1), 20 g/kg (G2), or 30 g/kg in rations respectively, for 8 weeks. After a two-week adaptation period to cages, the hens were allocated to 7 groups with 9 replicates of 1 hen in per cage each. The replications were allotted equally into the upper and lower cages to minimize the effects of cage level. In this study, egg yolk cholesterol had a decrease (p <0.05) in supplemented diet( sumac seed and ginger root powder). Fatty acid content in yolk; saturated fatty acid, monounsaturated fatty acids, polyunsaturated fatty acids and rate of n6/n3 were not significant (p <0.05). However, dietary supplementation with sumac and ginger powder reduced and yolk/blood cholesterol concentrations in laying hens. Supplementation of sumac and ginger affected on HDL, there was found a significant effect (p < 0.05) in treatment groups. Moreover, LDL positively decreased in all treatment groups compared with the control group. The findings of this study suggested that feeding sumac and ginger tend to be decreasing cholesterol levels in both yolk and blood on laying hens. It can be concluded that ginger root and sumac seed powder can be used as an effective feed additive to improve fatty acid composition and yolk and blood cholesterol in ATAK-S laying hens.

Effect of Dietary Sumac Seed Powder as Antioxidants and Growth Promoter on Egg Production Performance and Blood of Japanese Quail Laying

“…While, LDL level decreased significantly, HDL levels increased in the sumac group compared to the control. Gurbuz and Salih (2017) found that supplementation sumac (10,20 and 30g/kg)or ginger power (10,20 and 30 g/kg)in hens diets significantly increased HDL and decreased LDL and cholesterol levels in the blood of hens. On contrary, Sharbati et al (2013) found that the blood total protein of sumac or vit.…”

“…Onkar et al (2011) revealed that the seeds of sumac are rich in phenolic compounds and the isolated aromatic compounds showed antifungal activity against candida albicans and aspergillus flavus. Gurbuz and Salih (2017) found that contents of chemical composition of sumac seed, total phenolic (2.46%) and total flavonoid (4.81%). The animal experiments have shown that R. coriaria also has caused protection in inner organs.…”

“…Supplementation of the drinking water (0.02 g/kg per animal) has decreased the formation of oxidized DNA bases in colon, liver, lung and lymphocytes; also after gamma-irradiation pronounced effects have been observed (Chakraborty et al 2008). Mansoub (2011), Golzadeh, et al (2012, Kheiri et al (2015) and Gurbuz and Salih (2017) reported that when used sumac powder in broiler or laying hens diets increased the HDL, reduces the total cholesterol, very low LDL and plasma fasting blood sugar. Also, Shata and El-Moustafa (2017) found that quail fed sumac seed powder(1.5,2 and 2.5%) had the heaviest (P≤0.05) BW, FC, total antioxidants capacity, better, HDL, FCR and improve the immune response as compared to the control.…”

Ginger and Its Derivatives as Promising Alternatives to Antibiotics in Poultry Feed

“…This may be explained by the radical-scavenging effect of phenolic compounds and antioxidant components in ginger extract, which reduce lipid oxidation [63] and enhance the function of body organs as partly reflected by decreased the serum activities of ALT and AST, thus improving the production and synthesis of antioxidant enzymes [64]. On the same line, Gurbuz and Salih [65] found that powder of ginger root lowered yolk cholesterol content. The hypocholesterolemic effect of this plant was also recorded in broiler chickens [18].…”

Consuming egg yolk decreases body weight and increases serum HDL and brain expression of TrkB in male SD rats

“…It was thus ascertained that dietary cholesterol, including egg yolk, is harmful to the arteries . Hen breeders even started to select hen lines that produce eggs with low cholesterol or tried to including additives to reduce the cholesterol of shell eggs . This made people (especially including the health conscious) choose only the egg white – albumin – for food and discard the yolk.…”
