Effects of Using a Multi-Strain Probiotic on Performance, Immune Responses and Cecal Microflora Composition in Broiler Chickens Reared Under Cyclic Heat Stress Condition
This experiment was conducted to examine the effect of multi-strain probiotic (Primalac) on performance, immune responses and cecal microflora in broiler chickens under cyclic heat stress condition. A total of 96 one-d-old mixed sex broiler chicks (Ross 308) were weighed and randomly allocated to two treatment groups, each with 4 replicate pens of 12 chicks. The dietary treatments were basal di...
متن کاملEffect of Trehalose on the Expression of Heat Shock Protein 70 Gene in PC12 Cells Treated with Hydrogen Peroxide
Background and purpose: Oxidative stress is implicated in the pathogenesis of various diseases, including neurological disorders. In such stressful conditions, heat shock protein 70 (HSP70) protects cells, thus its pharmacological induction can be protective. The disaccharide trehalose exhibits various beneficial effects, including antioxidative effect. However, its impact on HSP70 is not obvio...
متن کاملInvestigation of the Effect of Silver Nanoparticles Coated on Zeolite on Performance, Intestinal Morphology and Gastrointestinal Microbial Population in Broiler Chickens under Heat Stress Conditions
Nowadays silver nanoparticles are being considered as an alternative to antibiotics. Silver is one of the most important elements in nanotechnology due to extensive antibacterial activity. The aim of present experiment was to evaluate the effect of silver nanoparticles coated on zeolite and organic acids on performance, intestinal morphology, gastrointestinal microbial population and carcass ch...
متن کاملEffect of Chromium Methionine Supplementation on Performance and Serum Metabolites in Broiler Chickens Thermoneutral and Under Heat-Stress Conditions
The effects of chromium methionine supplementation on performance and serummetaboliteswere evaluated in broiler chickens.Two experiments were conducted at22 oC, thermoneutral, (TN) and33±2 oC, heat stressed (HS) conditions. Two hundred and eighty eight male broiler chicks (Ross 308) were allocated to four treatments in a completely randomized design. Treatments with 0 (control), 200, 400 or 800...
متن کاملInduction of Heat-Shock Protein 70 Expression by Geranylgeranylacetone Shows Cytoprotective Effects in Cardiomyocytes of Mice under Humid Heat Stress
BACKGROUND Increasing evidence has revealed that humid heat stress (HHS) causes considerable damage to human health. The cardiovascular system has been suggested to be the primary target of heat stress, which results in serious cardiovascular diseases. However, there is still a lack of effective approaches for the prevention and treatment of cardiovascular diseases induced by HHS. OBJECTIVE H...
