Ginger extract enhances antioxidant ability and immunity of layers

Abstract

This experiment was to investigate ginger extract on production performance, antioxidant ability and immunity of laying hens. A total of 600 Hy-Line brown laying hens aged at 25 wk old were randomly divided into 2 treatments, 4 replicates per treatment, 75 layers each replicate. The control group hens were fed a basal diet; the experimental group hens were fed basal diets with 0.1% ginger extract. The results were shown as follows: 1) ginger extract significantly enhanced laying rates (P < 0.05) and daily egg weight (P < 0.05), substantially reduced the ratio of feed to egg (P < 0.05) of the hens; 2) ginger extract did not change the activities of glutathione peroxidase (GSH-PX) and total antioxidant capacity (TAOC) but significantly improved plasma superoxide dismutase (SOD) activity (P < 0.05), reduced malondialdehyde (MDA) content (P < 0.05) of the birds; 3) ginger extract did not affect the contents of serum total protein (TP), albumin (ALB), globulin (GLB), but significantly increased lysozyme (LZM) activity (P < 0.05); 4) ginger extract also significantly reduced plasma prostaglandin E2 (PGE2) content (P < 0.05). This study shows that ginger extract not only can improve the birds' antioxidant capacity, enhance immune function, but also has a potential of reducing inflammatory response.

Impact of Ginger Root Powder Dietary Supplement on Productive Performance, Egg Quality, Antioxidant Status and Blood Parameters in Laying Japanese Quails

“…Egg mass was positively affected by the treatments compared with the control group, which can be related to the positive effect of ginger powder on laying rate as well as egg weight [48]. In contrast to the current quail study, egg production rate was increased in ginger extract/powder fed laying hen [48,49] alone or in combination with medicinal herbs [27]. This means that the beneficial effect of ginger on performance depends on the bird species, dosage of ginger, and its derivatives and interaction with other dietary components.…”

“…An et al [44] mentioned that ginger extraction did not modify the action of GSH-PX and TAOC, but only modified plasma SOD feature, decreased MDA value of the birds. In addition, ginger extract did not modify the values of serum total protein, albumin, globulin, but positively magnified lysozyme (LZM) action.…”

“…On the other hand, Herve et al [37] noticed that egg productiveness features, and weekly weight of eggs were not clearly affected by oral application of ginger roots extracted basic oil. An et al [44] investigated ginger extract on the productiveness, antioxidant and immunity features of laying hens. The control birds were fed the basic diet; the experimental birds were fedbasic diets plus 0.1% ginger extract.…”
