1. Some aspects of chicken behavior and welfare
Brazil is the world leader in broiler production and export. It achieved this position mainly to its excellent supply chain structure and climate, which favor poultry and grain production throughout its territory. Although Brazilian egg production is not as important as broiler production, this segment presents great potential of increasing its share in the

2. Efeito do enriquecimento ambiental no comportamento e no cortisol fecal de Callithrix penicillata (É. Geoffroy, 1812) de cativeiro
Pela proximidade filogenética com os seres humanos os primatas não humanos são utilizados freqüentemente em estudos comparativos sobre o comportamento e como modelos experimentais na pesquisa biomédica. Contudo, o uso destes primatas implica numa série de questões éticas, incluindo as condições de seu cativeiro e os potenciais fatores da experiment

3. Traceability of poultry offal meal in broiler feeding using isotopic analysis (δ13C and δ15N) of different tissues
Our goal was to trace the inclusion of poultry offal meal (OM) in diets by using carbon (13C/12C) and nitrogen (15N/14N) isotopic ratios of different tissues in order to contribute for the development of an independent technology for the certification of the feeding of broilers reared on diets with no addition of animal ingredients. Eighty one-day-old chicks

4. The influence of feeding enrichment on the behavior of small felids (Carnivora: Felidae) in captivity
Animals in captivity are frequently exposed to environmental deprivation resulting in abnormal behaviors that indicate distress. The aim of the present study was to evaluate the effect of the "surprise pack" environmental enrichment technique in improving the welfare of small neotropical felids in captivity. In order to accomplish this, we used five individu

5. 13CO2 recovery fraction in expired air of septic patients under mechanical ventilation
The continuous intravenous administration of isotopic bicarbonate (NaH13CO2) has been used for the determination of the retention of the 13CO2 fraction or the 13CO2 recovered in expired air. This determination is important for the calculation of substrate oxidation. The aim of the present study was to evaluate, in critically ill patients with sepsis under me

6. COMPORTAMENTO DE PEQUENOS FELINOS NEOTROPICAIS EM CATIVEIRO
The lack of information concerning the small neotropical felids can be related to their predominant nocturnal activity, use of dense vegetation and hunting that threats natural populations. Therefore, research with captive animals may supply essential information for the development of effective conservation plans and strategies. The aim of this work was to

7. Enriquecimento de artÃmias com Ãcidos graxos para estudos de suplementaÃÃo em larvas de peixe / Artemia enrichment with fatty acids for supplementation studies in fish larvae
This work aimed to evaluate the alterations in Artemia salina lipid profile, after enrichment (16 hours) with experimental emulsions containing different concentrations of docosahexaenoic (DHA) and arachidonic acids (ARA), and the effects on growth, survival and fatty acids profile of curimba (Prochilodus lineatus) larvae, an omnivorous fresh water specie, f

8. Traceability of bovine meat and bone meal in poultry by stable isotope analysis
Bovine meat and bone meal (MBM) was widely used in animal diets until outbreaks of Bovine Spongiform Encefalopathy (BSE) occurred in some countries. It has not been confirmed yet whether or not BSE may be transmitted to man through chicken meat originated from poultry that had been fed diets containing MBM. Therefore, consumers nowadays express preference fo

9. A função Social do IPI
The eradication of poverty and social marginalization are some of the milestones of the Federative Republic of Brazil and of the Democratic Rule-of-law State. In this sense, its right to affirm that such objectives guide the national legal system in its entirety. The power of taxation, attributed to the State by the People, owner of the sovereignty, does not

10. Enriquecimento de zooplancton com Ãleo de peixe na larvicultura do Pacu Piaractus mesopotamicus e Curimbà Prochilodus lineatus / Enrichment of zooplÃncton with fish oil in larvicultura of pacu, Piaractus mesopotamicus and curimbatÃ, Prochiloduslineatus
The objective of this study was to evaluate the technical viability of the zooplÃncton enriched with acids graxos used in the feeding of pacu (Piaractus mesopotamicus) and curimbatà (Prochilodus lineatus) larvaes. In the Station of Fish farming of the Federal University of Lavras (UFLA), was made the isolation of stumps, the cladocerans and copepods cultur

11. Effects of pH, Temperature, and Nutrients on Propionate Degradation by a Methanogenic Enrichment Culture
Enrichment cultures were used to determine the conditions promoting fastest methanogenic propionate degradation and growth by adapting the cultures to various physical and chemical conditions and measuring the specific growth rate. We found that the fastest growth of propionate oxidizers occurred at pH 6.8 to 8.5 and 32 to 45°C. Acetate-degrading population

12. Uniformly 13C-labeled algal protein used to determine amino acid essentiality in vivo.
The edible alga Spirulina platensis was uniformly labeled with 13C by growth in an atmosphere of pure 13CO2. The labeled biomass was then incorporated into the diet of a laying hen for 27 days. The isotopic enrichment of individual amino acids in egg white and yolk proteins, as well as in various tissues of the hen at the end of the feeding period, was analy
