13. Identificação de novas possíveis variantes do Infectious Bursal Disease Virus (IBDV) / Identification of possible new variants of Infectious Bursal Disease Vírus (IBDV)
The Brazilian poultry industry is the worlds leading exporter of chickens meat. One of main agents causing losses is the virus of infectious bursal disease-IBDV, belonging to the family Birnaviridae.There are two serotypes of IBDV: serotypes 1 and 2, and all the viruses able to cause disease in birds belong to serotype 1. In Brazil, the virus has been respon

14. Infectious bronchitis in Brazilian chickens: current data and observations of field service personnel
The infectious bronchitis virus (IBV) was detected for the first time in Brazil by Hipólito in 1957 in chickens sold life in the municipal market of Belo Horizonte, MG, when commercial poultry production was just starting in that country. The Massachusetts (Mass) serotype was identified. However, the clinical disease was only observed in 1975, when poultry

15. Etiology and immunology of infectious bronchitis virus
Infectious bronchitis virus (IBV) of chickens is currently one of the main diseases associated with respiratory syndrome in domestic poultry, as well as with losses related to egg production. The etiological agent is a coronavirus, which presents structural differences in the field, mainly in the S1 spike protein. The immune response against this virus is co

16. Caracterização histoquímica e imunoistoquímica de áreas telencefálicas da coruja-da-igreja (Tyto alba) / Histochemical and immunohistochemical characterization of forebrain areas in the barn owl (Tyto alba)
Owls possess exceptional visual and auditory capacities. There is only limited information about the neuroanatomy of their forebrain. Thus, we characterized by histo/immunohistochemical techniques the forebrain of the barn owl. The basal ganglia were delineated by their intense immunostaining for DARPP-32 and tyrosine hydroxylase. Primary thalamorecipient se

17. Estratégias de forrageamento e evitação de predadores em Charadriidae e Scolopacidae na Baía de Todos os Santos, Bahia, Brasil
Shorebirds (Charadriidae and Scolopacidae) are a notable component of coastal ecosystems, especially of bays and estuaries. The great majority of these species is migratory, conducting long trips between Arctic and Sub-arctic breeding grounds and temperate and tropical wintering grounds. My general objective of this thesis was to analyze the foraging and pre

18. Diversidade de aves em um fragmento de restinga no Litoral Norte do Rio Grande do Sul, Brasil / Bird diversity of a Restinga area in northern coast of Rio Grande do Sul, Brazil
O litoral norte do Estado do Rio Grande do Sul vem sofrendo um aumento em sua urbanização nos últimos 30 anos, com significativas perdas de áreas naturais. As comunidades de aves dessas áreas são pouco conhecidas e seus hábitats têm sido rapidamente destruídos. Apenas alguns fragmentos preservam a vegetação de restinga original da costa do Rio Gra

19. Avaliação da transmissão e contaminação de codornas japonesas (Coturnix japonica) por Salmonella Pullorum. / Assessment of transmission and contamination of Japanese quail (Coturnix japonica) with Salmonella Pullorum.
The quail raising is a consolidated activity in poultry commercial alternative. Due to this development, new research is emerging to better productivity in all activities of this sector. Thus the health of these birds becomes an important field of study in large-scale production of quail for both the production of egg and for the production of cut. One of th

20. Field evaluation of broiler gait score using different sampling methods
Brazil is today the world's largest broiler meat exporter; however, in order to keep this position, it must comply with welfare regulations while maintaining low production costs. Locomotion problems restrain bird movements, limiting their access to drinking and feeding equipment, and therefore their survival and productivity. The objective of this study was

21. Coloração ultravioleta e pigmentária em aves de Uberlândia-MG / Ultraviolet and pigmentary colouration in birds of the Uberlândia MG
Bird feathers exhibit colors that are important for intra- and inter-specific communication. These colours transmit information that be conclusive for sexual selection, predator/prey relations or to indicate the nutritional condition of the individual, besides other aspects. Information about the functionality of plumage colouration in Brazilian birds is pra

22. Evaluation of the broiler locomotors problems using different methodologies of the gait score / Avaliação de problemas locomotores em frangos de corte utilizando diferentes metodologias de gait score
Brazil is today one of the largest poultry meat producer and exporter of the world; however, in order to continue in this production level and quality it is needed to apply animal welfare principles maintaining the same production costs. Locomotors problems keep away the bird from moving freely and to access the needed equipments for its survival: feeder and

23. Desenvolvimento de metodologias para determinação do bem-estar e massa corporal de frangos de corte por meio de análise digital de imagens / Development of methodologies for determination of broiler chicken welfare and body mass by means of digital image analysis
Advances have been made in the field of image processing as a technology for development of a consistent response in relation to new standards in animal welfare. One of the advantages of artificial vision systems in relation to those of human vision is the ability to make exact measurements, based on pixel count. This system also has no influence on animal b

24. Influence of artificial magnetic fields upon the behavior of the shrimp Litopenaeus vannamei (PENAEIDAE) and fish catch using fishtraps / InfluÃncia do campo magnÃtico artificial sobre o comportamento do camarÃo Litopenaeus Vannamei (PENAEIDAE) e a captura de peixes na pesca com covos
This work focuses on the behavior of marine organisms (fishes and shrimps) when submitted to artificial magnetic fields and on the use of this behavior as a mechanism to attract or to move away these organisms to/for specific areas. Although the geomagnetic field has existed in the planet a long time before of the beginning of the life rise little is known a
