| 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... |

| The objective was to evaluate the use of ractopamine (RAC) in the diet for pacu (Piaractus mesopotaminus) in the finishing phase on some quality parameters of the fillets. Thirty-five animals weighing 0.868±0.168kg were distributed in a completely randomised design with five treatments (0.0 - control; 11.25, 22.50, 33.75 and 45 ppm of RAC) and seven replicates with two fillets obtained from the same animal. The diets were isocaloric and isoprotein and experimental time was 90 days. RAC did not affect (P>0.05) the initial pH or ph after 24 hours of the fillets. Compared to the control, RAC increased (P<0.05) the moisture content of the fillets in natura and lipid oxidation of samples stored for 12 days in the refrigerator or freezer for 60 days.... |

| Avaliou-se o efeito da inclusão de fitase em dietas com proteína bruta (PB) e fósforo disponível (Pd) reduzidos sobre o desempenho, rendimento de carcaça e cortes e quantidade de poluentes na cama de frangos dos 22 aos 42 dias de idade. Foram utilizados 1200 pintos aos 21 dias, média de peso inicial de 646±8g, distribuídos em blocos ao acaso em esquema fatorial 3x3+1 (três porcentagens de Pd - 0,2, 0,3 e 0,4% - e três de PB - 14, 16 e 18% - e um tratamento adicional, padrão) em seis repetições de 20 aves cada. A fitase (500FTU/kg) foi adicionada nas dietas com fósforo reduzido (0,2 e 0,3%). Aos 42 dias as aves foram abatidas e amostras das camas foram encaminhadas para análise. Em dietas com reduzido teor de PB, melhor desempenho e rendimento de carcaça e... |

| 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... |
