Zulkifli, I., Dass, R. T. and Che Norma, M. T. 1999. Acute heat-stress effects on physiology and fear-related behaviour in red jungle fowl and domestic fowl. Can. J. Anim. Sci. 79: [165][166][167][168][169][170]. Two experiments were conducted to compare heat tolerance of red jungle fowl (RJF) and commercial broilers (CB) at (i) a common age and (ii) a common body weight. In exp. 1, RJF and CB of a common age (8 wk) were exposed to 36 ± 1°C for 6 h. RJF had smaller increases in heterophil to lymphocyte ratios and body temperature and higher serum cholesterol concentrations than CB in response to the heat treatment, while tonic immobility (TI) measurements were not affected by heat stress. In exp. 2, RJF and CB of a common body weight (1000 ± 150 g) were subjected to similar procedures as in exp. 1 (except TI durations). Both breeds responded similarly to the heat treatment. In both experiments, RJF had higher serum glucose level than CB, and the trait was not affected by heat exposure. Deux expériences ont été réalisées pour comparer la tolérance à la chaleur des galliformes rouges d'Asie (GRA) et des poulets de chair de production commerciale (PC) à un même âge et à un même poids corporel. Dans l'expérience 1, les GRA et les PC du même âge (8 semaines) étaient exposés à une température de 36 ± 1°C pendant 6 h. Les GRA manifestaient des accroissements moins importants du rapport hétérophiles-lymphocytes et de la température corporelle ainsi qu'une plus forte concentration sérique de cholestérol que les PC en réponse au traitement thermique. Par ailleurs, les valeurs d'immobilité tonique (IT) n'étaient pas touchées par le stress thermique. Dans l'expérience 2, les GRA et les PC de poids corporel comparable (1 000 ± 150 g) étaient exposés aux mêmes conditions que dans l'expérience 1, excepté pour la durée de IT. Les deux types de volaille réagissaient de la même façon au traitement thermique. Dans les 2 traitements les GRA avaient un niveau sérique de glucose plus élevé que les poulets domestiques et ce caractère se maintenait en présence de stress thermique.

Key words:Quails, Heat stress, Organic selenium and chromium, Immune response, oxidative stress This study conducted to clarify the effect of dietary supplementation of organic chromium (Cr), selenium (Se) and their combination on performance, immune responses, hematological and biochemical parameters as well as antioxidant capacity of Japanese quails (Coturnix japonica) under heat stress. A 90-day trial conducted using seventy-five, 10-day-old Japanese quails that randomly divided into 5 groups of 15 birds each. The 1 st group received basal diet and kept in a temperature controlled room at 24°C. The other four groups reared under natural summer months and kept in a room temperature ranged from (25.3°C to 36.7 °C). The 2 nd group kept under heat stress condition and fed basal diet only. The third, fourth and fifth groups fed basal diet supplemented by chromium (1400 µg/kg of diet), selenium (0.3 mg/kg of diet) and their combination respectively. In heat-stressed quail group, the data of growth performance revealed a significantly (P<0.05) reduced body weight gain (BWG), total feed intake (TFI) and a significantly (P<0.05) increased feed conversion ratio (FCR). A significantly (P<0.05) reduced phagocytic activity (PA), phagocytic index (PI) and the antibody titer against Newcastle disease virus as well as high mortality rate. a macrocytic hypochromic anemia and stress picture of leukogram. A significant (P<0.05) reduction in total proteins, albumin and thyroid hormones concentrations together with a significantly (P<0.05) elevated activity of serum AST, LDH, raised total cholesterol, triglycerides and glucose concentrations. Moreover, a significant (P<0.05) increase for lipid peroxidation marker (MDA) and a significant (P<0.05) reduction of glutathione peroxidase (GSH-Px), and total anti-oxidant capacity (TAC). However, simultaneous dietary supplementation with organic Cr and/or Se alleviated heat stress adverse effects. It could be concluded that combined dietary supplementation of organic Cr and Se can be considered to be a protective management in a quail diet, reducing the negative effects of heat stress.

“…Kutlu and Forbes (1993) reported that ascorbic acid reduces the synthesis of corticosteroid hormones in birds. By decreasing synthesis and secretion of corticosteroids, vitamin C alleviates the negative effects of environmental stress such as cold stress-related depression in poultry performance (McDowell 1989;Pardue et al1985).…”

Sahin K., N. Sahin: Effects of Chromium Picolinate and Ascorbic Acid Dietary Supplementation on Nitrogen and Mineral Excretion of Laying Hens Reared in a LowThe effects of chromium (chromium picolinate, CrPic) and ascorbic acid (L-ascorbic acid) supplementation on nitrogen (N), ash and mineral retention in laying hens (Hy-Line) reared under a low ambient temperature (7 o C) was evaluated. One hundred and twenty laying hens (32-weekold) were divided into four groups, 30 hens per group. The laying hens were fed either a basal diet or the basal diet supplemented with either 400 µg of Cr/kg of diet, 250 mg of L-ascorbic acid /kg of diet, or 400 µg of Cr plus 250 mg of L-ascorbic acid/kg of diet. Retention of N, ash, Ca, P, Zn, Fe and Cr were highest with the combination of chromium and ascorbic acid and were lowest with the control diet (P < 0.05). Accordingly, excretion of N, ash Ca, P, Zn, Fe and Cr was lesser in chromium and ascorbic acid supplemented groups than the control (P < 0.05), that of combination of supplemental chromium and ascorbic acid being lowest. Results of the present study show that supplementing ascorbic acid and chromium, particularly as a combination, improved retention of mineral and decreased excretion of nitrogen, ash, Ca, P, Zn, Fe, and Cr in laying hens. Such a combination of supplementation can offer a potential protective management practice in preventing the detrimental effects of cold stress in laying hens. The results of the present study also show that chromium and vitamin C had additive effects on parameters measured at the present study.
