Segurança, saúde e ergonomia de trabalhadores em galpões de frangos de corte equipados com diferentes sistemas de abastecimento de ração Safety, health and ergonomics of workers in poultry houses systems equipped with different feed supply

open access: yesEngenharia Agrícola, 2011
O abastecimento de ração nos galpões avícolas pode ser feito de forma manual ou automática, e por demandar esforço acredita-se que o abastecimento manual pode expor o tratador a sobrecarga física.

Les processus inflammatoires chez les oiseaux : physiopathologie et implications cliniques en aviculture [PDF]

open access: yes, 2010
Chez les oiseaux comme chez les mammifères, les processus inflammatoires font partie intégrante des mécanismes de défense de l’organisme. Ils se développent au cours de nombreuses maladies aviaires (tant virales, bactériennes que parasitaires), selon un ...

The influence of pair duration on reproductive success in the monogamous ‘Alalā (Hawaiian crow, Corvus hawaiiensis)

open access: yesFrontiers in Conservation Science
Conservation breeding program practitioners select potential mates in an attempt to maximize pair compatibility and maintain genetic diversity. Therefore, pair duration, or the number of breeding seasons that individuals retain the same mate, is ...

Importance of using genetic data to inform conservation captive breeding: A tale of two species of threatened macaws (Ara spp.)

open access: yesConservation Science and Practice, EarlyView.
Unmanaged captive populations of threatened species often harbor hidden genetic risks, so using genomic tools, we audited a large private macaw collection and uncovered extensive hybridization and high inbreeding. Our findings provide an actionable framework for how routine genetic screening can be used to mitigate these risks, manage captive breeding ...

The dynamics of avicultural markets [PDF]

open access: yesEnvironmental Conservation, 2001
Trade restrictions stemming from the Convention on International Trade in Endangered Species (CITES) have created a situation in which rare and attractive bird species command high prices on international pet markets. Most of these species are of tropical or subtropical origin, and many are amenable to captive breeding.

Transcriptional profiling and pathway analysis reveal differences in pituitary gland function, morphology, and vascularization in chickens genetically selected for high or low body weight

open access: yesBMC Genomics, 2019
Background Though intensive genetic selection has led to extraordinary advances in growth rate and feed efficiency in production of meat-type chickens, endocrine processes controlling these traits are still poorly understood. The anterior pituitary gland
