Effects of ginger root (Zingiber officinale) processed to different particle sizes on growth performance, antioxidant status, and serum metabolites of broiler chickens

Abstract

A study using 144 one-day-old Arbor Acres broilers was conducted to assess the effects of dried ginger root (Zingiber officinale) that was processed to particle sizes of 300, 149, 74, 37, and 8.4 microm on growth performance, antioxidant status, and serum metabolites of broiler chickens. The birds were housed in 24 wire cages in an environmentally controlled room. Dietary treatments were no supplementation (control) and supplementation with ginger root processed to 5 particle sizes at the level of 5 g/kg of diet. Average daily gain, ADFI, and feed conversion rate of chicks of each cage were measured weekly. Blood samples from 8 broilers per treatment were obtained at d 21 and 42 of the experiment to determine antioxidant enzymatic activities and metabolites in the serum, and the birds were subsequently killed to determine carcass yield and abdominal fat content. All broilers had similar ADFI or feed conversion rate over the entire experimental period. However, broilers supplemented with ginger powder tended to have higher ADG and had greater (P=0.014) carcass yield compared with that of the control. Supplementation of ginger increased (P<0.001) activities of total superoxide dismutase and glutathione peroxidase but reduced (P<0.01) concentrations of malondialdehyde and cholesterol in serum of broilers at 21 and 42 d of age. Concentration of total protein in serum of ginger-supplemented broilers tended (P=0.092) to be higher at 21 d and was higher (P=0.002) at 42 d of age compared with that of control broilers. Reducing particle size of ginger powder linearly reduced (P<0.05) cholesterol (d 21) and linearly increased (P<0.05) glutathione peroxidase (d 21), total superoxide dismutase (d 42), and total protein (d 21 and 42). Supplementation of ginger at the level of 5 g/kg improved antioxidant status of broilers and the efficacy was enhanced as the particle size was reduced from 300 to 37 microm.

Effects of Ginger (Zingiber officinale) Rhizomes Essential Oil on Some Reproductive Parameters in Laying Japanese Quail (Coturnix coturnix japonica)

“…These results are consistent with those of Zhang et al [29] in broiler chickens treated with ginger rhizomes powder at doses of 5 g/kg of diet. Conversely, other researchers recorded a significant decrease in serum proteins and globulins in broilers treated with ginger roots powder [20] [30].…”

Effects of Vitamin A on Growth Performance, Antioxidant Status and Blood Constituents in Lactating Grey Goat

“…Activity of GSH-Px was detected with 5, 5'-dithiobis-ρ-nitrobenzoic acid by measuring the OD of the reaction solution at 412 nm. One unit of GSH-Px activity was defined as the amount of enzyme per 0.1 mL of serum that would catalyze the conversion of 1 μmol L −1 of GSH to oxidized GSH at 37°C in 5 min (Zhang et al, 2009). The concentration of Malondialdehyde (MDA) was determined with a MDA Assay Kit A003 (Institute of Biological Engineering of Nanjing Jianchen, Nanjing, China).…”

Effect of dietary supplementation of ginger extract on growth, carcass characteristics and haematological parameters in broilers

“…For example, Taylor (2001) showed that the use of ginger and ginger powders significantly increased body weight and improved feed conversion compared to birds fed with control diet. In contrast, Zhang et al (2009) examined the effect of processed ginger with different size on growth performance and showed that the ginger additive had no significant effect on the feed efficiency, while body weight and daily weight gain of birds fed with ginger supplements were higher than control group. It is also reported that serum cholesterol levels in broilers can be decrease 0.4 or 0.6% ginger powder.…”
