Effects of Dietary Supplementation with Turmeric Rhizome Extract on Growth Performance, Carcass Characteristics, Antioxidant Capability, and Meat Quality of Wenchang Broiler Chickens

Abstract

Our study aimed to determine the effect of increasing dietary levels of turmeric rhizome extract (TRE) on performance, carcass characteristics, antioxidant capability and meat quality of Wenchang broiler chickens. Three hundred, 1-day-old Wenchang broiler chickens were brooded together for 2 weeks, then randomly allocated into four treatments with five replicates of 15 birds each. Birds were fed a corn-soybean basal diet supplemented with TRE at 0, 100, 200 and 300 mg/kg for 12 weeks. The results revealed that a TRE-supplemented diet had no significant effect (P>0.05) on the body weight, although birds fed a diet with TRE at 100 and 200 mg/kg had higher average daily weight gains and average daily feed as compared to controls from 9 to 12 week (P<0.05). Also, the addition of TRE at 100 to 300 mg/kg had a better feed conversion ratio compared to controls from week 9 to 12 (P<0.05). Dietary supplementation with TRE at 300 mg/kg increased the breast muscle weight ratio (P<0.05). Meanwhile, dietary supplementation with TRE at 100 to 300 mg/kg reduced the abdominal fat ratio (P<0.05), compared to that of the control group. TRE increased enzymatic activities of superoxide dismutase and glutathione peroxidase, and reduced malondiadehhyde concentrations, compared to the control group. Dietary TRE supplementation at 300 mg/kg decreased the drip loss in both breast muscle and thigh muscles, compared with the control group (P<0.05). In conclusion, dietary TRE supplementation enhanced antioxidant capability, growth performance, breast muscle weight ratio, and reduced the abdominal fat ratio of Wenchang broiler chickens.

Effect of decocted turmeric on performance, hematological parameters and carcass traits of broiler chickens

“…Hosseini-Vashan et al (2012), also reported that feeding turmeric powder did not affect weigh gain, feed intake, feed conversion ratio and production index of broiler chickens. Concomitantly, Wang et al (2015) reported that turmeric rhizome extract had no significant effect on the body weight of Wenchang broiler chickens. The exact rationale for the discrepancy results above remains unclear.…”

“…This result was in agreement with Durrani et al (2006) showing a higher relative weight of breast and thigh meats in turmeric powder fed broilers. Concomitantly, Decocted Turmeric for Broiler Chicks (I. Isroli et al) 267 Wang et al (2015) reported that supplementation with turmeric rhizome extract increased the absolute and relative weight of breast muscle of Wenchang broiler chickens. Regarding the negative effect of decocted turmeric, when provided at 100% in the drinking water, on the weight of breast muscle, this result was in contrast to the most of published reports earlier (HosseiniVashan et al, 2012;Wang et al, 2015).…”

Effect of dietary supplementation with &lt;i&gt;Rhizopus oryzae&lt;/i&gt; or &lt;i&gt;Chrysonilia crassa&lt;/i&gt; on growth performance, blood profile, intestinal microbial population, and carcass traits in broilers exposed to heat stress

“…For the entire assays in the whole blood and serum, the intra-assay and inter-assay coefficients of variation of the control samples were 1.5-4.8 and 2.7-5.4 %, respectively. Drip loss of meat was measured according to Wang et al (2015) with a few modifications. Around 45 min after slaughter, the breast or thigh muscles were weighed and the pH was measured.…”

Immunity, Antioxidant Status, and Performance of Broiler Chickens Fed Turmeric (Curcuma Longa) Rhizome Powder

“…Alagawany et al (2015) studied the effect of turmeric (0.5%) in broiler chickens and they recorded that catalase (CAT), SOD activities and GSH concentration were significantly increased due to turmeric. Turmeric extract was increased the enzymatic activities of SOD and glutathione peroxidase, and reduced MDA concentrations, compared to the control group (Wang et al, 2015). Nadia et al (2008) reported a lower MDA formation in the egg yolk of laying hens fed turmeric in concentrations of 1 and 5 g/kg during the laying period.…”
