Abstract
Stressful situations reduce the welfare, production indices and immune status of chickens. Salmonella spp. are a major zoonotic pathogens that annually cause over 1 billion infections worldwide. We therefore designed the current experiment to analyse the effects of 31±1°C heat stress (HS) (from 35 to 41 days) on performance parameters, Salmonella invasion and small intestine integrity in broiler chickens infected with Salmonella Enteritidis. We observed that HS decreased body weight gain and feed intake. However, feed conversion was only increased when HS was combined with Salmonella Enteritidis infection. In addition, we observed an increase in serum corticosterone levels in all of the birds that were subjected to HS, showing a hypothalamus–pituitary–adrenal axis activation. Furthermore, mild acute multifocal lymphoplasmacytic enteritis, characterized by foci of heterophil infiltration in the duodenum, jejunum and ileum, was observed in the HS group. In contrast, similar but more evident enteritis was no...

Studies on the environmental conse- quences of stress are relevant for economic and animal welfare reasons. We recently reported that long-term heat stressors (31 ± 1oC and 36 ± 1oC for 10 h/d) applied to broiler chickens (Gallus gallus domesticus) from d 35 to 42 of life increased serum corticosterone con- centrations, decreased performance variables and the macrophage oxidative burst, and produced mild, mul- tifocal acute enteritis. Being cognizant of the relevance of acute heat stress on trop...

Heat stress can induce hyperthermia in poultry. A reduction in heat load can be achieved by increasing the possibilities for dissipation, decreasing the level of heat production or by changing the thermal production pattern within a day. Strategies to reduce the negative effects of heat stress can be based on a specific feeding strategy, such as restricted feeding. Feed that is offered long enough before a hot period can ameliorate the harmful effects of high temperature. Another strategy may be...

Bidirectional signalling between the gastrointestinal tract and the brain is regulated at neural, hormonal and immunological levels. This construct is known as the brain-gut axis and is vital for maintaining homeostasis. Bacterial colonisation of the intestine plays a major role in the post-natal development and maturation of the immune and endocrine systems. These processes are key factors underpinning central nervous system (CNS) signalling. Recent research advances have seen a tremendous impr...

Studies on environmental consequences of stress on ammal production have grown substantially in the last few years for economic and animal welfare reasons. Physiological, hormonal, and immunological deficits as well as increases in animals' susceptibility to diseases have been reported after different stressors in broiler chickens. The aim of the current experiment is to describe the effects of 2 different heat stressors (31 ± 1 and 36 ± 1°C/10 h per d) applied to broiler chickens from d 35 to 4...

AbstractBackgroundThe ability to control uptake across the mucosa and protect from damage of harmful substances from the lumen is defined as intestinal barrier function.

Stress has long been recognized as a putative modulator of immunity. Several clinical and experimental reports point to a role of physical and psychological stressors on progression or resistance to disease. Nonetheless, literature in this field is sometimes controversial due to the wide variety of stressors employed and parameters of immunity analyzed. This variation should not be considered a consequence of methodological inaccuracy. The stress response, although theoretically stereotyped in n...

Cyhalothrin, a pyrethroid insecticide, induces stress-like symptoms, increases c-fos immunoreactivity in the paraventricular nucleus of the hypothalamus, and decreases innate immune responses in laboratory animals. Macrophages are key elements in cellular immune responses and operate at the tumor-host interface. This study investigated the relationship among cyhalothrin effects on Ehrlich tumor growth, serum corticosterone levels and peritoneal macrophage activity in mice. Three experiments were...

article i nfo A corticosterone model was used to study the effects of chronic and repeated stress during the rearing phase on physiology, the onset of lay and performance of laying hens in the subsequent laying period. Two hundred and seventy Hy-line brown layer pullets were reared in environmentally controlled battery cages. At 7, 11, and 15 weeks of age birds were exposed for 1 week to the following treatments in drinking water: corticos- terone dissolved in ethanol, ethanol, or untreated wate...

The intestinal barrier is formed by en- terocyte membranes, tight junctions, secreted mucus, and immunologic factors, such as tissue macrophages. Dysfunction of this barrier can be caused by different types of stress (e.g., physiological, pathological, psy- chological, pharmacological) and can lead to increased intestinal permeability. Increased permeability to endo- toxin, a component of the walls of gram-negative bacte- ria, causes local or systemic inflammatory reactions, or both. The immune ...

Summary Avian systemic salmonellosis is primarily caused by Salmonella enterica serovar Gallinarum and serovar Pullorum causing the diseases Fowl Typhoid and Pullorum Disease respectively. During infection interaction with the immune system occurs in three main phases. First is invasion via the gastrointestinal tract. Infection with S . Pullorum or S . Gallinarum does not cause substantial inflammation, unlike S . Typhimurium or S . Enteritidis. Through in vitro models it was found that S . Gall...

Abstract This study investigated the effect of a novel phosphorylated tocopherol mixture (TPM) on the growth performance, nutrient digestibility, meat quality, and blood plasma markers of inflammation in broilers reared in normal temperatures (NT) or cyclical high temperatures (CHT). TPM has previously been shown to increase the oral bioavailability of lipid soluble nutrients. Following a preliminary dose optimisation study, three hundred and sixty Ross 308 day old broilers were housed in groups...

Abstract Heat stress has a relevant effect on animal health and productivity. Stress and environmental changes can contribute to disease development, such as avian necrotic enteritis (NE). The goal of this study was to analyze the effects of heat stress applied to broiler chickens in an experimental model of co-infection with Clostridium perfringens and Eimeria spp. Therefore, the current study was designed to analyze the effect of heat stress to broiler chickens in an experimental model of infe...

Abstract Information on the dynamics of the chicken immune system during bacterial or parasite challenge in the presence or absence of stressful situations may provide a better understanding of the complex mechanisms behind these diseases. Necrotic enteritis (NE) had been controlled previously by the proper use of antimicrobial agents; however, more recently, NE has reemerged in many countries. The imposed restrictions on antimicrobial use and/or the intensive productive programs implemented by ...

Heat stress is a non-specific physiological response of the body when exposed to high ambient temperatures, which can break the balance of body redox and result in oxidative stress that affects growth performance as well as the health of poultry species. Polyphenols have attracted much attention in recent years due to their antioxidant ability and thus, can be an effective attenuator of heat stress. In this paper, the potential mechanisms underlying the inhibitory effect of polyphenols on heat s...

Abstract Worldwide, the effect of climatic variations has become a great challenge in poultry production. As global climate is changing, it alters the environmental temperatures, precipitation patterns and atmospheric carbon dioxide. Poultry farming mainly depends on climatic conditions such as temperature and humidity. Several factors can be involved but heat stress is one of most important environmental factor influencing a wide range of chickens performances including reduced feed intake whic...
