1. CHARACTERIZATION OF THE THERMAL ENVIRONMENT IN BROILER HOUSES WITH DIFFERENT CLIMATE CONTROL SYSTEMS
ABSTRACT The environment control of broiler houses must be done adequately to provide good thermal conditions to broilers without wasting energy. The objective of this study was to characterize the thermal environment in two mechanically ventilated broiler houses with a negative pressure ventilation system, one with a cellulose pad evaporative cooling system

3. Eucalyptus oil to mitigate heat stress in broilers
ABSTRACT The objective of this study was to evaluate performance, hematological parameters, leukocyte counts, and respiratory microbiota of broilers under heat stress receiving eucalyptus oil supplementation. Cobb broilers (n = 1200) were randomly distributed on the first day of life in a factorial arrangement with additional treatment (2 × 2 + 1) with two

4. Ticks in wild animals at a resort and the first documentation of Amblyomma sculptum infesting Emu (Dromaius novaehollandiae)
Resumo O estudo teve como objetivo identificar espécies de carrapatos presentes no ambiente e entre animais de cativeiro em Mangaratiba, Rio de Janeiro, Brasil. Os carrapatos foram removidos manualmente de animais de cativeiro e no ambiente usando a técnica de arrasto em flanela. Um total de 91 carrapatos foram capturados (51 adultos, 25 ninfas e 15 larva

5. Testing camera traps as a potential tool for detecting nest predation of birds in a tropical rainforest environment
ABSTRACT Identification of the predators of bird nests is essential to test ecological and evolutionary hypotheses and to make practical management decisions. A variety of nest monitoring devices have been proposed but many remain difficult to set up in the field. The aim of this study was to test camera traps as a potential tool to study predation of natura

6. Physiological Responses of Slow-Growing Chickens under Diurnally Cycling Temperature in a Hot Environment
ABSTRACT Free-range chicken production has significantly increased in recent years and it often entails exposing birds to cyclic environmental conditions. The objective of the current study was to investigate the effect of bird strain and sex, and rearing system on the physiological responses of Potchefstroom Koekoek (PK), Ovambo (OV) and Naked Neck (NN) chi

7. TECHNICAL FEASIBILITY OF THE ACCLIMATIZATION SYSTEM IN AVIARY OF POSTURE: A CASE STUDY
ABSTRACT: The objective of this study was to compare the performance of laying hens between automated aviaries, one with and another without acclimatized system. On a daily basis it was registered in each aviary the mortality, the egg production, and the feed consumption. The variables of the dry bulb temperature, relative humidity and black globe temperatur

8. Evaluation of microbial contamination of feces and soil on a laying-hen farm depending on sampling site and season
ABSTRACT The objective of the present study was to evaluate soil collected from a laying-hen farm and bird manure according to the season of the year and sampling site. Soil samples were taken at the poultry facility wall and at the distances of 15 m and 45 m from the building. Bird feces samples were collected inside the poultry house at the entrance and at

9. Turkey Wattle Temperature Response to Distinct Environmental Factors
ABSTRACT Rearing environmental conditions are important for turkey production, because this bird is particularly sensitive to heat stress. This study aimed at measuring the wattle temperature response of turkeys of three different ages (61, 96, and 131 days old) exposed to different combinations of dry bulb temperature, relative humidity, and wind speed rang

10. Model-predicted ammonia emission from two broiler houses with different rearing systems
Ammonia (NH3) emissions from broiler production can affect human and animal health and may cause acidification and eutrophication of the surrounding environment. This study aimed to estimate ammonia emissions from broiler litter in two systems of forced ventilation, the tunnel ventilation (TV) and the dark house (DH). The experiment was carried out on eight

11. Broiler Surface Temperature and Behavioral Response under Two Different Light Sources
Light is an important environmental variable for the regulation and control of broiler behavior. Some light sources may also add heat to the rearing environment, and indirectly affect the heat exchange between the birds and the environment. This study aimed at investigation the surface temperature and behavioral response of broilers reared in an environment

12. Phlebotomine fauna, natural infection rate and feeding habits of Lutzomyia cruzi in Jaciara, state of Mato Grosso, Brazil
Visceral leishmaniasis (VL) in Brazil is transmitted by the phlebotomine Lutzomyia longipalpis and in some midwestern regions by Lutzomyia cruzi. Studies of the phlebotomine fauna, feeding habits and natural infection rate by Leishmania contribute to increased understanding of the epidemiological chain of leishmaniases and their vectorial capacity.
