Dietary supplementation of Zingiber officinale and Zingiber zerumbet to heat‐stressed broiler chickens and its effect on heat shock protein 70 expression, blood parameters and body temperature

Abstract

The present study was conducted to assess the effects of dietary supplementation of Zingiber officinale and Zingiber zerumbet and to heat-stressed broiler chickens on heat shock protein (HSP) 70 density, plasma corticosterone concentration (CORT), heterophil to lymphocyte ratio (HLR) and body temperature. Beginning from day 28, chicks were divided into five dietary groups: (i) basal diet (control), (ii) basal diet +1%Z. zerumbet powder (ZZ1%), (iii) basal diet +2%Z. zerumbet powder (ZZ2%), (iv) basal diet +1%Z. officinale powder (ZO1%) and (v) basal diet +2%Z. officinale powder (ZO2%). From day 35-42, heat stress was induced by exposing birds to 38±1°C and 80% RH for 2 h/day. Irrespective of diet, heat challenge elevated HSP70 expression, CORT and HLR on day 42. On day 42, following heat challenge, the ZZ1% birds showed lower body temperatures than those of control, ZO1% and ZO2%. Neither CORT nor HLR was significantly affected by diet. The ZO2% and ZZ2% diets enhanced HSP70 expression when compared to the control groups. We concluded that dietary supplementation of Z. officinale and Z. zerumbet powder may induce HSP70 reaction in broiler chickens exposed to heat stress.

Expression profile of six stress-related genes and productive performances of fast and slow growing broiler strains reared under heat stress conditions

“…They play an important role in protein assembling and disassembling ( Pelham, 1985 ), protein folding and unfolding ( Randall and Hardy, 1986 ), and protein translocation ( Murakami et al, 1988 ). Of the many expressed HSPs, those with a molecular weight of approximately 70 kDa, named HSP70, have been extensively studied in chicken because they seem to best correlate with heat tolerance ( Gabriel et al, 1996; Soleimani et al, 2011; Hasheimi et al, 2012; Gu et al, 2012 ;).…”

Synthesis of Analogues of Gingerol and Shogaol, the Active Pungent Principles from the Rhizomes of Zingiber officinale and Evaluation of Their Anti-Platelet Aggregation Effects

“…Ginger (Chinese name: Shengjiang), derived from the rhizomes of Zingiber officinale Roscoe, is a well-known spice and is most frequently prescribed as a traditional Chinese medicine for its stomachic, antiemetic, antidiarrheal, expectorant, antiasthmatic, hemostatic and cardiologic properties for the treatment of several gastrointestinal and respiratory diseases [1–3]. The most famous traditional medicinal application of Z. officinale is to promote blood circulation for the removal of blood stasis, a mechanism that is related to anti-platelet aggregation activity [4,5].…”

Effects of In Ovo Supplementation with Nanonutrition (L-Arginine Conjugated with Ag NPs) on Muscle Growth, Immune Response and Heat Shock Proteins at Different Chicken Embryonic Development Stages

“…HSP-70 is a reliable index of stress in chickens while "3-hydroxyl-3-methyl-glutaryl coenzyme A reductase" has been used as an indicator of stress [34]. Pretreatment with L-Arg markedly reduced the dramatic downregulation of HSP-60 and HSP-70 in a hypoxic rat model.…”
