1. Nutrient requirements of paricá (Schizolobium parahyba var. amazonicum): optimizing seedling quality for reforestation programs
RESUMO Os programas de reflorestamento da Amazônia enfatizam o uso de espécies nativas da região. No entanto, o reflorestamento com espécies nativas requer a produção de mudas de alta qualidade. O presente estudo teve como objetivo avaliar o desenvolvimento e a qualidade de mudas de paricá (Schizolobium parahyba var. amazonicum), espécie nativa da Am

2. Temporal variation of bacterial population and response to physical and chemical parameters along a petrochemical industry wastewater treatment plant
Abstract: The petrochemical industry has played a considerable role in generation and release of waste in the environment. Activated sludge and facultative lagoons are commonly used for domestic and industrial wastewater treatment due to their low-cost and minimal need for operational requirements. Microorganisms present in wastewater treatment plant (WWTP)

3. Visual symptoms and nutritional deficiencies in olive plants subjected to nutrient deprivation
ABSTRACT. As the fourth largest importer of olive oil and the fifth largest importer of olives, Brazil is one of the largest importers of olive (Olea europaea L.) products in the world. In recent decades, the introduction and growth of olive cultivars with lower chilling requirements in the south and southeast regions of Brazil have made olive production via

4. Dietary protein requirements for tambaqui Colossoma macropomum (Cuvier, 1818) juvenile
RESUMO O tambaqui, Colossoma macropomum, é uma das espécies nativas da fauna brasileira com grande potencial de expansão, todavia, os estudos de exigências nutricionais são escassos e apresentam resultados conflitantes, a ponto de não termos informações suficientes para formular dietas específicas para a espécie, nas diferentes fases de crescimento

5. Biomass Deposition and Chemical Composition of Litterfall in Clonal Eucalyptus Plantations
ABSTRACT Productivity in clonal eucalyptus plantations depends on the genetic material and on the demand and cycling of nutrients, making studies that evaluate these requirements necessary. The aim of this study was to evaluate the effect of management (with and without thinning) on the deposition, chemical composition and nutrient contribution in litter at

6. Phosphorus requirement and partitioning in oat cultivars
RESUMO: A adubação de reposição varia com a demanda e a partição de nutrientes, mas isso é pouco conhecido em relação as cultivares de aveia. O estudo objetivou avaliar se a demanda e a partição de fósforo (P) diferem entre cultivares de aveia-branca. As cultivares ‘UPFA ‘Ouro’, ‘UPFPS Farroupilha’, ‘IPR Afrodite’, ‘URS 21’, �

7. Adjustment of nonlinear models and growth parameters and body nutrient deposition in meat-type and laying quail
ABSTRACT The objective of this study was to determine the adjustment quality of non-linear models and estimate the growth parameters and body chemical composition of a meat-type quail strain (Coturnix coturnix coturnix) and two laying quail strains (Coturnix coturnix japonica), designated yellow and red. The study used 1500 quail, not sexed, distributed in a

8. Nutritional plans of digestible phosphorus for growing-finishing barrows
ABSTRACT This study was conducted to evaluate nutritional plans of digestible phosphorus for barrows weighing between 30 and 100 kg. Eighty animals were distributed in a randomized block design with five nutritional plans containing 2.19-1.86-1.71, 2.57-2.23-2.09, 2.94-2.61-2.46, 3.32-2.99-2.84, and 3.70-3.36-3.32 g of digestible phosphorus kg−1 of diet, r

9. Metabolizable Energy Levels for Meat-Type Quails at Starter Phase
ABSTRACT This experiment was conducted to evaluate the effects of dietary nitrogen-corrected apparent metabolizable energy (AMEn) levels on meat-type quail performance and carcass traits from 1 to 14d of age. A total of 1120 not sexed meat-type quails were randomly distributed to seven treatments, with eight replicates with 20 quails each. A basal corn and s

10. SWINE WASTEWATER: IMPACTS ON SOIL, PLANT, AND LEACHATE
ABSTRACT: The use of animal-origin residues as a nutrient source without prior and proper investigations on their positive and negative impacts can affect the quality of agricultural soils and the environment into which they are inserted. In this sense, the aim of this study was to assess the impact of swine wastewater and mineral fertilization application o

11. CORN FERTILIZATION USING SWINE WASTEWATER AND SOIL-WATER ENVIRONMENTAL QUALITY
ABSTRACT: Soil application of swine wastewater for nutrient cycling may represent a correct destination of these residues and reduction in production costs. However, when applied to soil, such residue may cause environmental impacts. This study aimed to analyze the chemical characteristics of the soil, corn, and leachate after successive swine wastewater app

12. Diagnosis of mycobacteria in bovine milk: an overview
ABSTRACT Tuberculosis remains as the world’s biggest threat. In 2014, human tuberculosis ranked as a major infectious disease by the first time, overcoming HIV death rates. Bovine tuberculosis is a chronic disease of global distribution that affects animals and can be transmitted to humans by the consumption of raw milk, representing a serious public healt
