Abstract

ABSTRACT A total of 480 1-week-old chicks of about similar average weight, and size were divided into 6 groups. One group served as control, and was fed only basal diet, second group was fed ginger at the rate of 5 g/kg (T1), third group was given organic selenium (Se) at the rate of, 0.3 mg/kg diet (T2), fourth group was given organic Se at the rate of 0.4 mg/kg (T3), fifth group was fed with organic Se at the rate of 0.3 mg/kg + 5 g/kg ginger (T4), sixth group was given organic Se at the rate of 0.4 mg/kg + 5 g/kg ginger (T5). Mean feed intake was significantly (P < 0.05) high in T3 and T5 while body weight was significantly (P < 0.05) high in T3 compared to the control. Mean feed conversion ratio (FCR) was significantly (P < 0.05) high in T2, T3 and T5 compared to the control. Dressing percentage was significantly (P < 0.05) high in T4 and T5 compared to the control. Serum Antibody titre against Newcastle disease and paraoxonase (PON1) were significantly (P < 0.05) high in the T4 and T5 groups compared to the control while melanodialdehyde (MDA) concentration was significantly (P < 0.05) low in the same groups. Results of this study showed that ginger at the rate of 5 g/kg and Se at the rate of 0.4 mg/kg were more effective in improving the growth performance, immune response and antioxidant status in broiler chickens exposed to high ambient temperature.

Highlights

High ambient temperature causes major problems in the poultry industry in the form of high mortality, low feed intake and feed efficiency (Khan et al 2012a; Chand et al 2014)
Birds have limited physical resources to cope with the new challenge and birds need to redistribute the body reservoir of protein and energy at the cost of stunt growth (Khan et al 2012a)
The results of this study revealed that supplementation of different levels of organic Se and ginger improved feed intake, in all the supplemented, groups under heat-stressed broilers

Summary

Introduction

High ambient temperature causes major problems in the poultry industry in the form of high mortality, low feed intake and feed efficiency (Khan et al 2012a; Chand et al 2014). Nutritional approaches are considered to lessen the undesirable effects of heat stress by maintaining feed intake, water and electrolyte balance or by the supplementation of antioxidant vitamins, essential oils, minerals and natural herbs (Khan et al 2011; Rahman et al 2014a; Majid et al 2015; Abudabos et al 2016; Chand et al 2017). Supplementation of diets with natural antioxidants is a favourable strategy to decrease the lethal effects of heat stress in birds (Chand et al 2016)
