1. Diagnosis and validation by computational fluid dynamics of poultry house with negative pressure ventilation
RESUMO A ventilação à pressão negativa em aviários vem sendo utilizada para viabilizar a correção de seus microclimas internos, sendo que pesquisas apontam para a distribuição heterogênea do ar ao longo dos galpões e inadequação das variáveis ambientais às faixas recomendadas para o conforto térmico de aves adultas, especialmente nas horas ma

2. 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

3. Biological survey of a cloud forest in southwestern Mexico: plants, amphibians, reptiles, birds, and mammals
Abstract: Cloud forest ecosystems contain unique flora and fauna characterized by high levels of richness and endemism. However, this ecosystem is one of the most threatened because of land-use changes stemming from anthropogenic activities. Therefore, biological inventories are necessary to adequately assess the effects of land-use changes on species now an

4. EFFECT OF THERMAL STIMULATION IN EMBRYOS FROM COBB®GENETIC STRAIN UNDER COMMERCIAL SCALE
ABSTRACT Studies aimed at producing stronger birds and with better growth performance are being developed involving artificial incubation. To that extent, thermal stimulation by the heat of 1.39 ºC and 1ºC above the standard, and by cold of 36 ºC fixed, were applied in the last week of the embryonic development (day 14 to day 18) to Cobb® strain birds of

5. Ultrastructural Assessment of the Integrity of the enteric Mucosa of Commercial Turkeys Vaccinated against Coccidiosis
ABSTRACT The objective of this study was evaluated the villus integrity of commercial turkeys submitted to coccidiosis prevention methods and challenged with Eimeria field oocysts, using scanning electron microscopy. Sixty BUT 9 female commercial turkeys were distributed in a completely randomized block design split with two treatments: T1- control diet with

6. COMPARATIVE EVALUATION OF THE PROTECTIVE EFFICACY OF DIFFERENT VACCINATION PROGRAMS AGAINST A VIRULENT FIELD STRAIN OF THE NEWCASTLE DISEASE VIRUS IN BROILERS
ABSTRACT Despite the intensive vaccination programs used for controlling Newcastle disease (ND) in the Iranian poultry industry, outbreaks of ND have been reported in poultry farms. This study was conducted to evaluate the effectiveness of vaccines for the protection against ND infection and virus-shedding period of velogenic Newcastle disease virus (vNDV) f

7. Isolation, Identification and Molecular Characterization of Highly Pathogenic Newcastle Disease Virus From Field Outbreaks
ABSTRACT Newcastle disease (ND) is a major infectious disease of the poultry caused by a virulent strain of Avian Paramyxovirus - 1, that is a single strand non-segmented negative sense RNA virus. ND virus is major threat to the poultry industry in many countries of the world. The study was aimed to isolate and identify Newcastle disease virus (NDV) by using

8. Host specificity and experimental assessment of the early establishment of the mistletoe Phoradendron crassifolium (Pohl ex DC.) Eichler (Santalaceae) in a fragment of Atlantic Forest in southeast Brazil
Mistletoe establishment relies heavily on a seed reaching a proper host plant. Small frugivorous birds usually disperse large numbers of mistletoe seeds. However, in the field, mistletoes are absent from some potential available hosts. We investigated whether the mistletoe Phoradendron crassifolium has some preferences for specific host trees in a fragment o

9. PARÂMETROS IMUNOLÓGICOS FRENTE À CONTAMINAÇÃO POR SALMONELLA ENTERITIDIS EM AVES TRATADAS E NÃO TRATADAS COM ÁCIDOS ORGÂNICOS E SUA DETECÇÃO POR MÉTODOS FENOTÍPICOS E GENOTÍPICOS / IMMUNOLOGICAL PARAMETERS IN THE CONTAMINATION BY SALMONELLA ENTERITIDIS IN POULTRY TREATED AND NOT TREATED WITH ORGANIC ACIDS AND THEIR DETECTION BY PHENOTYPIC AND GENOTYPIC METHODS
Salmonellosis is a public health problem that involves issues in animal health and food handling practices that require combined actions to minimize its effects. This disease is a zoonosis with the greatest impact on public health throughout the world due to: high endemicity, high mortality and especially by its difficult to control and the development of an

10. Editorial
Even though the caatinga has been identified as an important area of endemism for South American birds, few studies have been conducted on the distribution, evolution and ecology of birds in this biome. Understanding how habitats contribute to maintain the regional bird diversity is extremely important. In this study, carried out in the backwoods of the stat

11. Recent advances in the study of avian malaria: an overview with an emphasis on the distribution of Plasmodium spp in Brazil
Avian malaria parasites (Plasmodium) have a worldwide distribution except for Antarctica. They are transmitted exclusively by mosquito vectors (Diptera: Culicidae) and are of particular interest to health care research due to their phylogenetic relationship with human plasmodia and their ability to cause avian malaria, which is frequently lethal in non-adapt

12. Baru: biologia e uso.
ABSTRACT: Dipteryx alata Vog. is a native leguminous tree species from Cerrado, the Brazilian Savannah. It is widespread and plays an important role as key species for environmental conservation as well as for rural families to get additional income by exploiting its seeds. Its wood, which is quite durable, is used for several applications in the farm; the c
