Does low-protein diet improve broiler performance under heat stress conditions?
(Fundação APINCO de Ciência e Tecnologia Avícolas, 2004-06-01)
Nutrition for broilers under high temperatures is extremely important for brazilian broiler chicken industry because the amounts of consumed nutrients and environmental temperature have great effects on bird performance ...
How heat stress (continuous or cyclical) interferes with nutrient digestibility, energy and nitrogen balances and performance in broilers
(2016-10-01)
The effect of continuous and cyclical heat stress on broiler growth performance, nutrient digestibility, energy and nitrogen balances was investigated. Four hundred and fifty, 21-day-old, Cobb male broilers were raised in ...
Effect of indomethacin on hyperthermia induced by heat stress in broiler chickens
(Springer, 1998-12-01)
An investigation was carried out to verify whether the heat stress hyperthermia response of broilers is prostaglandin-dependent. Male broiler chickens of the Hubbard-Petterson strain, aged 35-49 days, were used. Chickens ...
Does low-protein diet improve broiler performance under heat stress conditions?
(Fundação APINCO de Ciência e Tecnologia Avícolas, 2014)
Gut microbiota of drosophila subobscura contributes to its heat tolerance and is sensitive to transient thermal stress
(Frontiers Media, 2021)
The gut microbiota can contribute to host physiology leading to an increase of resistance to abiotic stress conditions. For instance, temperature has profound effects on ectotherms, and the role of the gut microbiota on ...
Physiological response of broilers raised under simulated conditions of heat wavesRespostas de frangos de corte criados sob estresse por calor
(2018-01-01)
To evaluate the influence of heat stress for up to 72 hours, and the possible cumulative effect of heat stress on the physiological responses of broilers raised under simulated conditions of heat waves, 500 male Cobb ...
Physiological responses of broiler chickens to heat stress and dietary electrolyte balance (sodium plus potassium minus chloride, milliequivalents per kilogram)
(2004-09-01)
Individually caged male Cobb broilers (24), 44 d of age, were used to evaluate effects of heat stress (1 d of data collection) and dietary electrolyte balance (DEB; Na + K - Cl, mEq/kg from 1 d of age). During summer ...
Carcass and meat quality traits of chickens fed diets concurrently supplemented with vitamins C and E under constant heat stress
(2016-07-28)
The objective of this study was to determine if a diet supplemented simultaneously with vitamins C and E would alleviate the negative effects of heat stress, applied between 28 and 42 days of age, on performance, carcass ...
Brain and hepatic Hsp70 protein levels in heat-acclimated broiler chickens during heat stress
(Fundação APINCO de Ciência e Tecnologia Avícolas, 2004-12-01)
In the present study we have investigated the effects of heat acclimation on brain and hepatic Hsp70 protein levels and body temperature of broiler chickens in response to gradual heat stress. Two groups of broilers were ...
Effect of moderate and severe heat stress on avian embryonic Hsp70 gene expression
(Growth Publishing Co Inc, 2002-06-01)
Stress response is a universal mechanism developed by all organisms to deal with adverse changes in the environment, which lead to the synthesis of heat shock proteins (Hsps). In this study, the effect of moderate (41degreesC) ...
