Behaviour of cockatiels (Nymphicus hollandicus) at two temperatures in captivity Arq. Bras. Med. Vet. Zootec.
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...

Caracterização da curva de crescimento de fêmeas Crioulas Lageanas criadas em condições naturais Arq. Bras. Med. Vet. Zootec.
Barbosa,E.A.; Egito,A.A.; Martins,V.M.V.; Martins,E.; Silva,J.P.; Ramos,A.F..
Morphometry and ultrasound of carcasses were used to estimate the growth curve of Criola Lageana cows, raised under natural conditions. A total of 111 cows, raised under extensively production system in Central Plateau of Santa Catarina, were evaluated. Morphometrics and ultrasound measurements were related with the age of the animals using the targeted univariate regression model, assigning the variable response to gamma distribution. The inflection points of the growth curve were 24 and 25 months for withers height and hip height, between 27 and 29 for weight, body length, rump length, thorax perimeter, depth and distance between ilea. For ribeye area (REA), inflection point was 18 months. The Crioula Lageana cows presented greater growth velocity around...

Use of collard green stalks as environmental enrichment for cockatiels ( Nymphicus hollandicus ) kept in captivity Arq. Bras. Med. Vet. Zootec.
Carvalho,T.S.G.; Saad,C.E.P.; Alvarenga,R.R.; Ferreira,W.M.; Assis,V.D.L.; Pereira,V.M.; Scalon,J.D.; Silva,J.P.; Zangeronimo,M.G..
ABSTRACT The objective of this study was to evaluate the influence of collard green stalks as environmental enrichment on the behavior of cockatiels (Nymphicus hollandicus) maintained in captivity. Sixteen birds were housed individually in cages and fed a commercial diet for parrots and seed mix, with water ad libitum during 12 days in climatic chamber with temperature and relative humidity simulating tropical conditions. The animals (n = 8) were divided into two groups, control and enriched, and the experimental period was divided into two phases (during and after enrichment) of four days each. The collard green stalks were used as enrichment only during the first period of the experiment, daily changed and maintained only during the day. The stalks...
