Abstract
Stressful stimuli are known to change the immune function. A relevant environmental stress to the poultry production is the heat stress. Salmonella spp. is one of the most important zoonotic pathogens worldwide. The aim of our work was search for effects of heat stress on broilers chickens infected with Salmonella enteritidis (SE), searching for a neuroimmune relationship. Two hundred and sixty chickens were divided in four groups:control (C); heat stress (HS); salmonella + control (PC); and salmonella + heat stress (PHS). The chickens were infected or not with Salmonella enteritidis (10 6 UFC/animal). Both HS and PHS groups were exposed to 31 ± 1 °C (10 h/day) from day 35 to 42. At the end of stress (42 nd day), we observed that heat stress decreased performance parameters such as body weight ( p p ; P p β , IL-10, TGF- β , AvBD4, AvBD6 and TLR-2 expression in chickens infected with SE. Heat stress also induced moderate enteritis in chickens of PHS group; additionally, heat stress increased bacterial migration to the spleen ( p Salmonella migration to the spleen.

Climatic warming will likely increase the frequency of extreme weather events, which may reduce an individual9s capacity for sustained activity due to thermal limits. We tested whether the risk of overheating may limit parental provisioning of an aerial insectivorous bird in population decline. For many seasonally breeding birds, parents are thought to operate close to an energetic ceiling during the 2-3 week chick-rearing period. The factors determining the ceiling remain unknown, although it m...

The experiment was performed with the aim of determining the effect of co-administration of antioxidant vitamins, retinol, ascorbic acid and α-tocopherol on rectal temperature (RT) fluctuations in pullets during the hot-dry season in Nigeria. Forty-eight Black Harco pullets, aged 16 weeks and weighing 1.5 ± 0.03 kg were divided by simple random sampling into two groups, consisting of 28 treated and 20 control Black Harco pullets. The RTs of 28 treated and 20 control Black Harco pullets were meas...

The experiment was performed to evaluate cloacal temperature (CT) responses in broiler chickens, administered with betaine and ascorbic acid (AA) during the hot–dry season. Broilers were divided into four groups: Group I (control) was given sterile water; Group II, betaine at 250 mg/kg; Group III, AA at 50 mg/kg and Group IV, betaine (250 mg/kg) + AA (50 mg/kg). The different solutions were given orally for 42 days. Dry-bulb temperature (DBT), relative humidity (RH) and temperature-humidity inde...
