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 ...
Performance and egg quality of Japanese quails submitted to cyclic heat stress
(Fundação APINCO de Ciência e Tecnologia Avícolas, 2012-03-01)
Aiming at evaluating the influence of cyclic temperatures on the performance and egg quality of Japanese quails an experiment was carried out with 480 birds after egg production peak. Birds were housed in a bioclimatic ...

Elevated extension of longevity by cyclically heat stressing a set of recombinant inbred lines of Drosophila melanogaster throughout their adult life
(Springer, 2016-11)
An extremely high (about 100 %) increase in longevity is reported for a subset of recombinant inbred lines (RILs) of Drosophila melanogaster subjected to a cyclic heat stress throughout the adult life. Previous work showed ...
Performance and carbon turnover in fast- and slow-growing broilers submitted to cyclic heat stress and fed on high-protein diets
(Taylor & Francis Ltd, 2016-01-02)
Two experiments were conducted to test the hypothesis that when using similar protein/amino acid diets and environment temperature conditions, the performance and carbon turnover in muscle and liver tissues, as measured ...

Effects of diet and cyclic daily heat stress on electrolyte, nitrogen and water intake, excretion and retention by colostomized male broiler chickens
(2004-01-01)
Male Ross broiler chicks were grown in a thermoneutral environment from 0 to 14 d. From 14 to 41 d, half the birds remained in the thermoneutral room (22.5 ± 3.5°C) whereas the other half in another room were exposed daily ...
