Correlations among behavior, performance and environment in broiler breeders using multivariate analysis
(Fundação APINCO de Ciência e Tecnologia Avícolas, 2007-12-01)
Animal welfare issues have received much attention not only to supply farmed animal requirements, but also to ethical and cultural public concerns. Daily collected information, as well as the systematic follow-up of ...
Logistic regression to estimate the welfare of broiler breeders in relation to environmental and behavioral variables
(Associação Brasileira de Engenharia Agrícola (SBEA), 2011-02-01)
As crescentes demandas e exigências dos mercados consumidores pelo bem-estar das aves nos aviários têm motivado diversas pesquisas científicas a monitorar e a classificar o bem-estar em função do ambiente de criação. Diante ...
Análise comparativa do ambiente de aviários de postura com diferentes sistemas de acondicionamento
Poulty house typology and the materials used (mainly for roofing) are the determining factors for an appropriate thermal condition aiming at production. In this context, the main point of this paper was to identify differences ...
Adequacy of thermal ambience in silk production sheds with different toppings
At every stage of life of the Bombyx mori there is a great temperature (between 20 and 28°C) and favorable humidity (greater than 70%) to their physiological development. This paper proposed analytical method for evaluating ...
Locally adapted Brazilian ewes with different coat colors maintain homeothermy during the year in an equatorial semiarid environment
The present paper aimed to show the thermoregulatory responses of locally adapted Morada Nova sheep with different coat colors that were exposed to direct solar radiation in an equatorial semiarid region. Animals were ...
Estimation of respiratory frequency and rectal temperature on pigs in heat stress by fuzzy logic
Physiological parameters such as respiratory frequency and rectal temperature stand out as indicators for heat stress in pigs, however, requiring time and labor for measurements. The possibility of using infrared thermography ...
Utilização de pelos de animais silvestres para monitoramento ambiental de Cd, Cr, Cu, Fe, Mn, Pb e Zn
(Sociedade Brasileira de Química, 2009)
This study investigates the use of wild animal hair of C. brachyurus, C. thous and L. pardalis as biomonitors of trace metal at Parque Nacional das Emas, Brazil. Results reveal a strong correlation between Cd and Pb as ...
