Heat stress in laying hens is prompted by combinations of environmental temperature and humidity that prevent the bird’s thermoregulatory process from effectively dissipating the heat produced during metabolism [32]. High environmental temperature is the major problem faced by laying hens as well as poultry farmers usually in summer months. The ideal temperature for laying hens is about 20°C [2...

this paper presents the analysis of the onset and withdrawal dates and the duration of summer monsoon over nepal for last 63 years (1951-2013). the trend analysis revealed that both the onset and withdrawal of summer monsoon are delayed in recent years. the statistical analysis using cumulative deviation and worsley likelihood tests showed a step jump in mean withdrawal date after the year 1997...

background: stress is a nonspecific reaction to everything the body needs. although occupational stress exists in every occupation, it is seen with more frequency and intensity amongst those occupations related to human health. in this study, we aimed to investigate the level of occupational stress in operating room staffs working in the hospitals affiliated to isfahan university of medical sci...

Heritability and interactions of yield and growth traits were assessed in Hevea brasiliensis using full-sib progenies and clonal populations. Using parent-offspring regression, annual mean rubber yield (ARY) and summer yield (SY) showed moderate to high heritability (ARY, h2 =34–56%; SY, h2 =36–52%). Among the yield components, girth exhibited low to moderate heritability (h2 =17–36%) while bra...

BACKGROUND: Camel and sheep have high disperse and tolerance in tropical regions. But different results of harsh condition tolerance ability of them have been reported. OBJECTIVES: The objective of this study was to determine the heat stress tolerance in camel and sheep by evaluating changes in blood serum metabolites and to report and compare the serum biochemical profile of sheep and camel du...

Biogeosciences Discussions This discussion paper is/has been under review for the journal Biogeosciences (BG). Please refer to the corresponding final paper in BG if available. Abstract The lipid content of seven samples of sinking particles collected with sediment traps moored at ∼100 m depth in summer and fall across the Canadian Beaufort Shelf (Arc-tic Ocean) was investigated. Our main goal ...

One way to probe earthquake nucleation processes and the relation between stress buildup and seismicity is to analyze the sensitivity of seismicity to stress perturbations. Here, we report evidence for seasonal strain and stress (~2–4 kPa) variations in the Nepal Himalaya, induced by water storage variations which correlate with seasonal variations of seismicity. The seismicity rate is twice as...

Hematological parameters were measured in 408 blood samples collected over a 30-mo period from 254 captive mountain gazelles (Gazella gazella) in Saudi Arabia. We evaluated the influence of sex, age, capture method, and season, on these parameters. Evaluations also were made with a small number of anesthetized animals. Males had a significantly higher mean corpuscular volume (MCV) and mean corp...

Laboratoire de production animale, Institut National Agronomique de Tunisie, département de production animale, 1082 Tunisie *Corresponding author, e-mail: [email protected] ABSTRACT: The aim of this study is to evaluate the effects of heat stress using temperature-humidity index (THI). Two experiments were conducted using lactating Friesian-Holstein cows to measure the effects of heat str...
