Antioxidant status, immune system, blood metabolites and carcass characteristic of broiler chickens fed turmeric rhizome powder under heat stress

Abstract

This experiment was conducted to evaluate the effects of dietary turmeric rhizome powder (TP) on performance, blood metabolite, immune system, antioxidant status, and relative weight of organs in pre and post heat stressed broilers. Two hundred and sixty-four (264) day-old male Arian broiler chicks were randomly allotted to three dietary treatments containing 0, 0.4 or 0.8% turmeric powder. Each diet was fed to four replicates of 22 birds each. Heat stress was applied for 5 h (33°C) from 28 to 42 days. Two birds from each replicate were randomly selected and blood samples were taken to collect the serum, plasma and whole blood. These were slaughtered to determine the relative weight of organs pre (28 days PHS) and after heat stress (42 days AHS). TP did not affect feed intake, body weight, feed conversion ratio (FCR), production index, and protein and energy efficiency ratio of broilers. Blood cholesterol and low density lipoprotein (LDL) decreased and blood high density lipoprotein (HDL) increased when fed TP in PHS and AHS birds. TP did not affect serum triglyceride, protein, antibody production against sheep red blood cell (SRBC), IgG, IgM and Newcastle vaccination (ND) in PHS and AHS. TP suppressed the enzyme activity of lactate dehydrogenase (LDH), aspartate aminotransferase (AST), alanine aminotransferase (ALT), and alkaline phosphatase (ALP) of heat stressed birds. The enzyme activity of creatine kinase (CK) in AHS and superoxide dismutase (SOD) in PHS were not affected by TP diets. TP diets increased blood activity of glutathione peroxidase (GPx) and SOD and decreased blood thiobarbituric acid reactive substances (TBARS) index. The H:L ratio, relative weight of bursa of fabircus and abdominal fat decreased in birds fed TP diets. TP diets did not alter percentage of bone Ash, and P of heat stress broilers; however, it increased bone Ca of heat stressed broilers. It can be concluded that the supplementation of TP to diets, decreased the activity of dehydrogenase enzyme, stressor index, and improved the antioxidant status without affecting performance and the immune system of heat stressed broilers.

Effect of different levels of honey on physiological, growth and carcass traits of broiler chickens during dry season

“…In the present study, the activity of AST and ALT enzymes did not follow a consistent trend with the inclusion of honey in the drinking water of broilers during stress. This supports the findings of Hosseini-Vashan et al (2012) who reported that turmeric powder depressed AST in heat stressed broiler due to the antioxidant curcumin which is a component of the additive. The similarity in levels of serum albumin and globulin in the birds offered different levels of honey and ascorbic acid in the present study differs from the findings of Al-Shanti (2005) who found that supplementing heat stressed broilers with 1 g vitamin C/l drinking water had no effect on blood albumin and globulin…”

Impact of Treating Hatching Eggs with Curcumin after Exposure to Thermal Stress on Embryonic Development, Hatchability, Physiological Body Reactions, and Hormonal Profiles of Dokki-4 Chickens

“…Similarly, the results of Zhai et al [ 42 ] indicated that curcumin compounds could reduce the oxidative injury and lipid metabolism disruption by modifying the cecum microbiota of White Pekin ducklings. Contrarily, the findings of Hosseini-Vashan et al [ 43 ] showed no significant difference in the relative weights of birds offered turmeric. The decreased RBCs and WBCs for chicks produced from eggs exposed to high incubation temperature could be attributed to the adverse effect of heat stress on the physiological status of the birds, consequently affecting oxygen uptake in the eggs for embryos.…”

Physiological parameters and productive performance of rabbit does and their offsprings with dietary supplementation of soy lecithin

“…It is known that oxidative stress results in reactive oxygen species formation and in decreased antioxidant reserve (Yoon & Park, 2014). Superoxide dismutase is an important defense enzyme that catalyzes the reduction of hydrogen peroxides and protects the tissues against highly reactive oxygen species, and glutathione, glutathione S-transferase, and glutathione peroxidase also catalyze the reduction of hydrogen peroxides and hydroxiperoxides to nontoxic products (Hosseini-Vashan et al, 2012). There was a reduction in the activities of alanine aminotransferase and aspartate aminotransferase.…”
