Environmental effect on the creation of quails: Review:

Abstract

The objective of this article to review the influence that environment plays in creating quail. The animal welfare has occupied a prominent place in farms since stress situations lead to a physiological state that is characterized as undesirable. The temperature and microclimate in the authoring system can be considered as physical factors having the greatest effect on the growth of quails, influencing directly on the feed use. Thermally stressed animals cannot efficiently take advantage of the nutrients provided by the diet, decreasing feed intake. To evaluate the thermal environment in which the animals are exposed, we use the Temperature Index Black Globe Humidity. Indexes vary in temperature and humidity caused by environmental conditions, reflect the change in the average surface temperature by modifying the physiological response of the animal. The vent temperature of the bird can also be an interpreted to identify conditions of comfort or thermal stress measurement representing the temperature of the body core. During heat stress, physiological, hormonal and molecular adjustments occur, causing modifications in function and structure of cells.
