Non-invasive genetic sampling for molecular sexing and microsatellite genotyping of hyacinth macaw (Anodorhynchus hyacinthinus)
Provedor de dados: 74
Autores: Presti,Flavia T.; Meyer,Janaína; Antas,Paulo T.Z.; Guedes,Neiva M.R.; Miyaki,Cristina Y.
Molted feather sampling is a useful tool for genetic analyses of endangered species, but it is often very laborious due to the low quality and quantity of the DNA obtained. In the present study we show the parts of feathers that resulted in better yield of DNA. In descending order these were: blood clot outside the umbilicus, umbilicus (without blood clot), tip, inner membrane, and small calamus. Compared to DNA extracted from blood samples, DNA extracted from feathers produced microsatellite alleles of poorer quality and had to be processed immediately after extraction. As expected due to the level of DNA degradation, molecular sexing protocols that result in shorter PCR products were more efficient.

ABSTRACT The incidence of the psittacine beak and feather disease virus (BFDV) was investigated in Brazilian native parrots with normal feathering arriving at rescue and triage centers for wild animals (CETAS, IBAMA) in the state of Minas Gerais, Brazil. BFDV DNA was investigated by previously described PCR technique for the partial amplification of BFDV ORF-1 in DNA extracts from blood, cloacal swab or liver of psittacines. Some birds provided more than one sample. Nine species of psittacines were sampled between January 2009 and October 2010. Blood (n=46) or cloacal swab (n=128) samples were obtained from psittacines immediately upon arrival at the triage centers. Liver samples were collected from necropsied birds dead on arrival (n=167). All swab...

Evaluation of the importance of the porta-renal system in parrots (Amazona aestiva)
Provedor de dados: 195

When injected in the thigh muscles of a bird, the local capillaries absorb the drug and the blood flow goes to the external iliac vein that has a porta-renal valve close to the kidney. Controlled by the autonomous nervous system, this valve can be opened or closed by the sympathetic or parasympathetic stimuli respectively. When opened, the blood flow goes to the renal vein then to the vena cava and reaches the systemic circulation. However, when the valve is closed, the blood flow goes to the renal parenchyma where it is mixed with the arterial blood. Thus, the kidney can excrete the drug that was given before it reaches the systemic circulation. The objective of this study was to evaluate the efficacy of ketamine when injected into the thigh or breast...

Undifferentiated carcinoma of the pancreas in a cockatiel ( Nymphicus hollandicus ): case report
Provedor de dados: 45
Autores: Carvalho,T.S.G.; Abreu,C.C.; Nakayama,P.A.; Wouters,F.; Saad,C.E.P.; Zangeronimo,M.G.
ABSTRACT Undifferentiated carcinoma of the pancreas is a malignant neoplasm that is uncommon among domestic species, especially cockatiels (Nymphicus hollandicus), one of the most popular birds kept as a pet throughout the world. The aim of this study was to describe the occurrence of an undifferentiated carcinoma in the pancreas of a cockatiel. A bird, an adult male that died naturally with swelling in the abdominal region, was referred to necropsy. Macroscopic examination showed poor body condition, the coelomic cavity filled with liquid and a white mass attached to the pancreas and other smaller masses attached to the duodenum. Tissue samples and organs were harvested and fixed in 10% buffered formalin, then routinely processed for histopathology and...

Behaviour of cockatiels (Nymphicus hollandicus) at two temperatures in captivity
Provedor de dados: 45
Autores: Carvalho,T.S.G.; Zangeronimo,M.G.; Saad,C.E.P.; Alvarenga,R.R.; Assis,V.D.L.; Pereira,V.M.; Scalon,J.D.; Silva,J.P.
Behavioural studies with cockatiels (Nymphicus hollandicus) in captivity are scarce. Due to the need for appropriate management of these animals, this study was performed to examine the behaviour of cockatiels kept in captivity at two temperatures. Sixteen cockatiels were individually housed in cages (62cm high x 43cm long x 27cm wide) and fed with a commercial ration and seed mixture for psittacids. Water was provided ad libitum. The eight-day experiment was divided into two stages of four days each. In the first stage, the birds were kept at room temperature (25°C) with 70% relative humidity during 24 hours. In the next stage, they were kept at 35°C from 06:00 to 18:00h and 25°C from 18:00 to 06:00h, also at 70% relative humidity. The behaviour of the...

Environmental enrichment on the behavior and welfare of cockatiels (Nymphicus hollandicus)
Provedor de dados: 45
Autores: Assis,V.D.L.; Carvalho,T.S.G.; Pereira,V.M.; Freitas,R.T.F.; Saad,C.E.P.; Costa,A.C.; Silva,A.A.A.
ABSTRACT This study evaluated the influence of physical environmental enrichment on the behavior of cockatiels (Nymphicus hollandicus). Eighteen birds, nine males and nine females, were monitored in environments enriched with wooden sticks and bead rings and in non-enriched environments, in a completely randomized design. Behavioral categories were grouped into locomotion, maintenance, rest, feed, undesirable activities, and interaction with environmental enrichment. Data were analyzed using descriptive analysis of behaviors to produce the ethogram and percentage comparison of frequency values for behavior analysis. Environmental enrichment positively influenced behavioral categories and some behavioral activities of birds.

Autores: Silva,Vanessa Rafaella Foletto da; Serafini,Patricia Pereira; Pedroso,Joice Reche; Leme,Denise Pereira; Kanaan,Vanessa Tavares.
ABSTRACT Avian hematologic reference intervals are useful tools to evaluate body homeostasis and diagnose diseases. However, there are few species-specific reference intervals published. The present study reports Vinaceous-breasted Amazon ( Amazona vinacea ) hematologic reference values obtained during the health status evaluation of release candidates as part of this species reintroduction efforts at the Araucárias National Park. Parameters reported are erythrogram (erythrocytes, hemoglobin, packed cell volume, mean cell volume, mean corpuscular hemoglobin concentration and mean corpuscular hemoglobin), Red Cell Distribution Width (RDW), white cells total and differential (heterophiles, lymphocytes, basophils, eosinophils and monocytes), thrombocytes and...
