Techniques to minimize the effects of acute heat stress or chronic in broilers
(2019-01-01)
High environmental temperature is limiting factor in broiler production. In order to minimize the undesirable consequences of acute or chronic heat stress, the techniques of fixed dietary electrolyte balance and early heat ...
Effect of acute heat stress on heat shock protein 70 messenger RNA and on heat shock protein expression in the liver of broilers
(Carfax Publ Co, 1996-05-01)
1. The synthesis of heat shock protein 70 (Hsp70) mRNA and the expression of Hsp70 in the liver of broiler chickens submitted to acute heat stress (35 degrees C for 5 h) was investigated.2. Hsp70 expression was detected ...

The strategic application of elecytolyte balance to minimize heat stress in broilers
(2015)
Several physiological and metabolic changes are triggered in broilers submitted to high environmental temperatures, resulting in performance losses. Feed formulation manipulation of the dietary electrolyte balance may be ...
Acute heat stress impairs performance parameters and induces mild intestinal enteritis in broiler chickens: Role of acute hypothalamic-pituitary-adrenal axis activation
(Amer Soc Animal ScienceChampaign, 2012)
Studies on the environmental consequences of stress are relevant for economic and animal welfare reasons. We recently reported that long-term heat stressors (31 +/- 1 degrees C and 36 +/- 1 degrees C for 10 h/d) applied ...
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 ...
Dietary electrolytes and thermal conditioning: minimizing heat stress in broilers
(2013)
In tropical climates the heat is one of the major constraints to production of broilers and is responsible for inducing a high mortality, especially in the finishing phase. Thus, the objective of this study was to compare ...
Expression of heat shock protein in broiler embryo tissues after acute cold or heat stress
(Wiley-Blackwell, 2004-02-01)
This study evaluated the expression of heat shock protein 70 kD (hsp70) in broiler chicken embryos subjected to cold (Experiment 1) or high incubation temperature (Experiment 11). In each experiment, fertile eggs were ...
