Heat Stress Condition

In this experiment, the effect of hydroalcoholic grape seed extract (GSE) and vitamin C feed supplementation on some blood parameters and heat shock protein 70 (<em>HSP70</em> gene) expression of broiler chickens suffering from chronic heat stress was investigated. Experimental diets included control diet (with no additive), 3 levels of GSE (150, 300, 450 mg/kg), and one level of vitamin C (300 mg/kg). Each diet was fed to 5 replicates of 12 male chicks each, from d 1 to 42. The birds suffered from chronic daily heat stress under 34±1°C temperature with 65 to 70% relative humidity for 5 h from 29 to 42 d of age. Results showed that 300 mg/kg GSE supplementation increased body weight of broilers both before and after heat stress condition (at 28 and 42 d, respectively). Also, birds fed 300 mg GSE/kg diet had higher European production efficiency factor during the whole period of the experiment. Supplementation of GSE decreased the concentration of serum glucose at 28 and 42 d; at 42 d (during heat stress condition) and at 450 mg/kg diet it decreased cholesterol, triglyceride, lowand very low density lipoprotein concentration of serum blood. Vitamin C supplementation decreased serum cholesterol concentration of broilers suffering from heat stress. <em>HSP70</em> gene expression in heart and liver of broilers reduced by GSE and vitamin C supplementation pre- and during chronic heat stress condition.

Negative Effect

The stress of high environmental temperature may have a deleterious influence on the performance of broiler chickens by reducing feed intake, live weight gain and feed efficiency. Exposing chicks to 36-38°C for 24h at 5d of age reinforces the resistance of older (6 to 7 wk-old) broilers to heat stress (De Basillo et al., 2003). Several studies have revealed that antioxidant nutrient supplementation especially vitamin C and E can be used to alter the negative effect of environmental stress (NRC, 1984). Combination of antioxidant vitamins generally shows greater antioxidant activity than that of each component alone. The objective of this study was to investigate the effects of early age thermal conditioning and vitamin C, E supplementation on performance, carcass characteristic in broiler chickens reared under heat stress.

Vitamin C Supplementation

Purpose:Prolonged physical exertion and environmental heat stress may elicit postexercise depression of immune cell function, increasing upper respiratory tract infection (URTI) susceptibility. We investigated the effects of acute and short-term vitamin C (VC) compared with placebo (PL) supplementation on URTI susceptibility, salivary immunoglobulin A (s-IgA), and cortisol responses in healthy individuals following prolonged exercise-heat stress.Methods:Twelve participants were randomized into the VC or PL group in a double-blind design. For 12 days, participants consumed 3 × 500 mg tablets of VC or PL per day, with testing completed at baseline, then following acute (1 d) and short-term (8 d) supplementation. Participants performed 120.1 ± 49.6 min of cycling at 54 ± 6% VO2max in a hot (34.8 ± 1.0°C and 13 ± 3% relative humidity) environment, with saliva samples collected at pre-, post-, and 72 h postexercise. Health logs specifying URTI symptoms were completed for 7 days postexercise.Results:A 2 × 3 × 3 mixed ANOVA with a post hoc Bonferroni correction factor revealed a significant linear trend in postexercise cortisol attenuation in the VC group, 21.7 ± 15.1 nmol/L (mean ± SD) at baseline, to 13.5 ± 10.0 at acute, to 7.6 ± 4.2 after short term (P = .032). No differences were detected in ratio of s-IgA to protein or URTI symptoms between groups.Conclusions:These data suggest that vitamin C supplementation can decrease postexercise cortisol in individuals performing exercise similar to that of a half-marathon or marathon in hot conditions. However, no changes in s-IgA and URTI were evident, possibly due to previous moderate training and reduced physical and psychological stress compared with athletes participating in ultramarathons.

Ziel der Studie war es, die Auswirkungen der Aufnahme von drei verschiedenen Vitamin C-Mengen (0, 200 und 400 mg / kg) in die Ernährung auf das Fettsäureprofil im Broilerbrustfleisch zu bewerten. Die Studie wurde in 3 Zyklen und 4 Wiederholungen in Dauer von 42 Tagen durchgeführt, an einer vollständig randomisierten Probe von 10 Hühnern pro Käfig, insgesamt 120 männliche Hühner im Alter von einem Tag des kommerziellen Hybrids Ross 308. Die Datenanalyse wurde unter Verwendung des statistischen SAS-Analyseprogramms vorgenommen, während der Vergleich der Mittelwerte mit dem Duncan multiplen Vergleichstest mit einer Fehlerwahrscheinlichkeit von 5% durchgeführt wurde. Die Ergebnisse zeigten, dass die Zugabe von Vitamin C in einer Menge von 200 mg / kg den Prozentsatz an gesättigten Fettsäuren wie Myristinsäure, Palmitinsäure und Stearinsäure verringert, wobei die Menge an ungesättigten Fettsäuren zunahm und die Menge an gesättigten Fettsäuren abnahm

This study was undertaken to evaluate the effect of adding vitamin C at (0,150 mg/kgfeed) and dietary calcium at (0.9,1.1%) on some productive performance of two differentstrains of broiler (Ross and Hubbard). A total of one hundred ninety-two birds(96 chicks foreach strain) one day old unsexed were used in this study. Each strain distributed randomly tofour groups (24) chicks for each treatment, two replicates of (12)chicks for each.The first groupwas fed on a basal diet supplemented with (0.0 vitamin C+0.9% calcium). The second group was fedon the same basal diet supplemented with (0.0 vitamin C +1.1% calcium). The third group was fedon a basal diet supplemented with (150 mg vitamin C/kg feed+0.9% calcium) and fourth groupwas fed on a basal diet supplemented with (150mg vitamin C/kg feed +1.1% calcium).Theresults of this study showed that growth performance of chicks was significantly improved inCo-supplemented vitamin C and calcium (1.1%) and there was no significant interactionbetween vitamin C supplementation and calcium on dressing percentage and mortality rate.
