This study aimed to investigate the effects of dietary fumaric acid (FA) on growth performance, immune responses, immune organ index and antioxidant status in broilers under chronic heat stress (HS). A total of 200 21-day-old Ross 308 chicks were randomly assigned in a 2 × 2 factorial arrangement with two diets (basal diet or 10 g/kg FA diet) and two temperatures (thermoneutral or HS) for 21 days. On day 42, growth performance, immune organ index, immune function and antioxidative ability were determined. HS resulted in a significant reduction in final body weight (FBW), average daily feed intake (ADFI), average daily gain (ADG), antibody titres against sheep red blood cells (SRBC) and Newcastle disease virus, IgM, IgG, relative weights of spleen, thymus and bursa of Fabricius, but a significant increase in the feed conversion ratio (FCR), activities of total superoxide dismutase (T-SOD) and glutathione peroxidase (GPx) in the bursa, contents of malondialdehyde and total carbonyl (TC) in thymus and bursa (P < 0.05). Dietary supplementation of FA increased FBW, ADFI, ADG, antibody titres against SRBC, IgG, relative weights of spleen and bursa, activity of GPx in thymus and bursa, whereas it decreased the FCR and TC of thymus and bursa. These results suggest that dietary 10 g/kg FA had positive effects on growth performance and immune function through improving the antioxidative capacity of immune organs.

Secretory Apparatus

Severe heat stress causes protein denaturation in various cellular compartments. If Saccharomyces cerevisiae cells grown at 24°C are preconditioned at 37°C, proteins denatured by subsequent exposure to 48–50°C can be renatured when the cells are allowed to recover at 24°C. Conformational repair of vital proteins is essential for survival, because gene expression is transiently blocked after the thermal insult. Refolding of cytoplasmic proteins requires the Hsp104 chaperone, and refolding of lumenal endoplasmic reticulum (ER) proteins requires the Hsp70 homologue Lhs1p. We show here that conformational repair of heat-damaged glycoproteins in the ER of living yeast cells required functional Hsp104. A heterologous enzyme and a number of natural yeast proteins, previously translocated and folded in the ER and thereafter denatured by severe heat stress, failed to be refolded to active and secretion-competent structures in the absence of Hsp104 or when an ATP-binding site of Hsp104 was mutated. During recovery at 24°C, the misfolded proteins persisted in the ER, although the secretory apparatus was fully functional. Hsp104 appears to control conformational repair of heat-damaged proteins even beyond the ER membrane.

Severe Heat Stress

The research was conducted to study the effect of heat stress on behavior, some physiological and blood parameters with nine goats of almost similar in age, sex and weight into three groups. Three groups were divided as zero hour (T0), four hours (T4) and eight hours (T8) heat exposure. Temperature–humidity index (THI) value was calculated as 28.17 which indicate the experimental animals were in extreme severe heat stress. Skin and rectal temperature had no significant differences among the treatment groups but respiration/panting and pulse rate were increased with the increased of heat stress from T0 to T8 group (P<0.01).  Significant difference was found in standing time and lying time (P<0.01) in experimental groups. There were significant changes (P<0.01) in number of urination and defecation per hour but no significant changes was found in duration per urination in heat treated groups. The amount of RBC, PCV%, Hb%, WBC were increased with the increased of heat stress (P<0.01). Neutrophil, eosinophil, lymphocyte and monocyte numbers increased significantly (P<0.01) in heat treated groups.  It can be concluded that heat stress had significant changes on some behavioral, physiological and blood parameters of goat.DOI: http://dx.doi.org/10.3329/pa.v22i1-2.16465 Progress.
