Concentrado proteico de arroz na alimentação do jundiá (Rhamdia quelen)

RESUMO O objetivo do presente trabalho foi avaliar a inclusão do concentrado proteico da destilação de etanol obtido de arroz (CPA) na alimentação do jundiá. Trezentos e setenta e cinco peixes foram distribuídos em sistema de recirculação de água com 15 caixas (125L). Foram testadas três dietas (37% PB e 3200kcal/kg de energia digestível), sendo uma controle e duas testando a substituição da proteína da farinha de peixe em 25% (CPA-25%) ou 50% (CPA-50%) pelo CPA. Aos 30 dias, foram avaliadas as variáveis de desempenho, composição corporal e índices somáticos. Os animais submetidos ao tratamento CPA-25% apresentaram resposta de crescimento equivalente aos que receberam o tratamento controle, mas superior aos peixes submetidos ao CPA-50%. Não foram observadas diferenças significativas entre os tratamentos para os índices somáticos avaliados. Os animais submetidos às dietas contendo CPA apresentaram maior teor de gordura corporal. Já a deposição de gordura corporal foi superior para os peixes alimentados com CPA-25%, e a deposição de proteína corporal menor para os alimentados com CPA-50%. Os resultados indicam que o CPA pode substituir em até 25% a proteína da farinha de peixe, sem comprometer o crescimento dos jundiás, tendo esse nível de substituição proporcionado, inclusive, uma redução de 8% no custo da dieta

Effect of dietary fiber concentrates on growth performance, gut morphology and hepatic metabolic intermediates in jundiá (Rhamdia quelen)

ABSTRACT A study was conducted to investigate the effect of Dietary Fiber Concentrates (DFCs) on growth performance, gut morphology, and hepatic metabolic intermediates in jundiá (Rhamdia quelen). At the end of the trial, growth and intestinal villus height was significantly (P< 0.05) higher in fish fed diets supplemented with DFCs. However, the animals in commercial prebiotic group showed higher values for this variable compared to the other treatments. Regarding the thickness of the epithelium bowel, it was greater in the Control group compared to animals supplemented with β-glucan+mannan. Likewise, treatment with commercial prebiotic showed higher values of epithelium bowel compared to the DFCs. The fish supplemented with DFCs, had higher glycogen storage compared to the control group. These results indicate that DFCs can be considered as a beneficial dietary supplement for improving growth performance, gut morphology, and hepatic metabolic intermediates of jundiá

Rice protein concentrate in the feeding of silver catfish (Rhamdia quelen)

<p></p><p>ABSTRACT The objective of this work was to evaluate the inclusion of protein concentrate from the distillation of ethanol from rice (CPA) in jundia feed. A total of 375 fish were distributed in water recirculation system with 15 boxes (125L). Three diets (37% PB and 3200kcal / kg digestible energy), one control and two were to test for the replacement of fishmeal protein by 25 (CPA-25%) and 50% (CPA-50%) by CPA. At 30 days, the variables of performance, body composition and somatic indexes were evaluated. The animals submitted to the CPA-25% treatment presented a growth response equivalent to those that received the Control treatment, but superior to the fish submitted to the CPA-50%. There were no significant differences between treatments for the somatic indices evaluated. Animals submitted to diets containing CPA had higher body fat content. Body fat deposition was higher for fish fed with CPA-25% and lower body protein deposition for those fed with CPA-50%. The results indicate that CPA can substitute up to 25% fish meal protein, without compromising the growth of jundias, and this level of substitution provided an 8% reduction in diet cost.</p><p></p

Team working and effectiveness in health care

With the arrival of the National Plan, this timely paper presents preliminary findings from a major survey of multidisciplinary team working and effectiveness. The three-year study covered primary, secondary and community health care teams

The effectiveness of teams in organizations: a meta-analysis

The proposed meta-analysis of 61 independent samples aims to identify whether, and if so under what conditions, team working in organizations is related to organizational effectiveness. Team working had a significant though small positive relationship with both performance outcomes and staff attitudes. Our contingency analyses further showed that team working had a stronger relationship with performance outcomes if accompanied by complementary HR measures and in non-health-care settings. Finally, we found that team working is more strongly related to attitudinal outcomes in Sociotechnical Systems and health-care settings
