1. The culture of Nile tilapia at different salinities using a biofloc system
RESUMO A influência da salinidade da água no cultivo da tilápia do Nilo com bioflocos foi avaliada por meio de indicadores de qualidade da água, desempenho zootécnico e bem-estar animal. Foram adotados cinco tratamentos, envolvendo salinidades (0, 4, 8, 12 e 16 g L-1) com três repetições. As tilápias foram cultivadas por 90 dias e estocadas em tanqu

2. Fontes de lipídios para juvenis de trairão (Hoplias lacerdae). / Sources of lipids for juvenile trairão (Hoplias lacerdae)
This study aimed to evaluate diets with different oil sources on juveniles of trairão (Hoplias lacerdae). Experimental design was completely randomized with five replications and four treatments (oils: canola, flaxseed, soybean and olive oils). Treatments were isonitrogenous (42% PB) and isocaloric (4569.29 kcal EB/kg), differing only in the source of oil.

3. Utilização de embriões liofilizados e flocos de Artemia na diversificação nutricional de pós-larvas do camarão marinho Litopenaes vannamei (Boone, 1931)
The objective of the current study was to evaluate the zootechnical performance (survival and growth) of Litopenaeus vannamei post-Iarvae fed an artificial shrimp diet supplemented with Artemia flakes or freeze-dried Artemia embryos. For that purpose, 20 culturing units were individually stocked with 50 shrimp post-Iarvae (average dry weight of 0,3 0,03 mg)

4. Effects of high density chickens creation on the zootechnical yield, cage environment. / Efeitos da criação de frangos em alta densidade sobre a ambiencia do galpão, o rendimento zootecnico e a qualidade da carne.
The chicken creation in high population density has been a worldwide practice with the objective of reducing production costs. This practice causes alterations in the creation ecosystem, interfering in the well-being of the birds, increasing feces and wastes concentration that results in higher formation of irritating gases as the ammonia. These environmenta

5. Desenvolvimento e avaliação de um sistema de resfriamento evaporativo, por aspersão intermitente, na cobertura de aviarios usando modelos de escala distorcida
Technical poultry production is presently requiring more environmental control on the thermal cornfort characteristics because of the use of high potential genetic birds, diets energy high levei, and an increase of birds density. The general objective of this research was to develop a system for roof cooling based on the evaporative cooling concept, using in
