Effect of ginger (Zingiber officinale Roscoe) and organic selenium on growth dynamics, blood melanodialdehyde and paraoxonase in broilers exposed to heat stress

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.

Effects of thyme essential oil and A, C, and E vitamin combinations to diets on performance, egg quality, MDA, and 8-OHdG of laying hens under heat stress

“…It is estimated that the economic losses will increase gradually in the near future due to the effects of global warming in tropical and semitropical regions (Khan et al 2014). The manipulation of environment or ration formulation is closely related to the applied cost and performance increments (Safiullah et al 2019). It is well known that when there is environmental heat stress in poultry, vitamins need such as vitamin C also gradually increases (Khan et al 2012a).…”

Effect of diet supplemented with phytogenics and protease enzyme on performance, serum biochemistry and muscle histomorphology in broilers

“…Therefore, recently the non-antibiotic substances have been given immense importance (Khan et al 2012b;Abudabos et al 2016;Akhtar et al 2020). Herbs and spices are also added into the poultry diet to improve feed intake and weight gain (Alzawqari et al 2016;Chand et al 2018;Safiullah et al 2019;Wahab et al 2019).…”

Effect of dietary inclusion of taurine on performance, carcass characteristics and muscle micro-measurements in broilers under cyclic heat stress

“…Numerous studies have documented the deleterious impact of heat stress on the performance of broiler (Khan et al 2014;Attia and Hassan 2017;Attia et al , 2018Rehman et al 2018;Safiullah et al 2019;Shah et al 2020). Limited studies have been published on the effect of taurine in heat-stressed broiler.…”

“…Due to high metabolic rate, lack of sweat glands and abundant feathers, broilers are sensitive to heat stress (Khan et al 2011). Huge economic losses are associated with heat stress via impaired growth and loss of meat quality, thus heat stress has become a serious problem for poultry producers (Attia and Hassan 2017;Attia et al , 2018Safiullah et al 2019;Shah et al 2019). In addition, heat stress can negatively affect carcass characteristics, quality and muscle histomorphology (Khan et al 2011;Attia and Hassan 2017;Attia et al , 2018Lu et al 2019;Shah et al 2020), which further increase the economic losses of the poultry industry (Rehman et al 2018).…”
