1. Determination of nutrient and energy values of cottonseed meal supplemented or not with phytase and protease for broiler chicks
ABSTRACT The objective of this study was to determine the nutritional and energy compositions of cottonseed meal (CM), with or without enzyme supplementation, for broilers at different ages. A total of 672 male Cobb 500 chickens were distributed into four metabolism and ileal-digestibility trials. The experimental design was completely randomized, with four

2. Elemental Concentration and Sulfur Chemical Speciation in the Amazonian Plant Andira surinamensis Using Synchrotron Radiation Techniques (SR-XRF, XANES), RBS and WD-XRF
The inorganic composition of the bark and leaf of a plant from the Amazon rainforest, Andira surinamensis, was determined using two non-destructive, multi-element techniques: X-ray fluorescence (XRF) and Rutherford backscattering spectrometry (RBS). XRF measurements were made using both a conventional X-ray source and synchrotron radiation. It was observed t

3. Obstructive urolithiasis in growing-finishing pigs
RESUMO: Urolitíase obstrutiva é uma enfermidade caracterizada pela presença de urólitos no trato urinário, com consequente obstrução das vias de excreção. Este artigo descreve os achados epidemiológicos e clínico-patológicos de 22 surtos de urolitíase em suínos de crescimento e terminação no Sul do Brasil. Os suínos afetados eram machos e cl

4. Chemical attributes of soil under cassava wastewater application in Marandugrass cultivation
RESUMO Existe grande preocupação mundial quanto ao manejo de resíduos agroindustriais, envolvendo práticas sustentáveis que contribuam para aproveitar os resíduos como insumos em processos produtivos, possibilitando maior eficiência na integração das atividades agropecuárias e mitigando seus efeitos negativos sobre o solo. Assim, objetivou-se avali

5. Phosphorus Fractions in Soil with Organic and Mineral Fertilization in Integrated Crop-Livestock System
ABSTRACT Use of organic fertilizers in integrated crop-livestock (iCL) systems may affect soil phosphorus fractions. This study aimed to determine phosphorus fractions in the soil under the iCL system after six years of application of organic or mineral fertilizers. The experiment was conducted on a Rhodic Kandiudox (Nitossolo Vermelho Distroférrico) in a r

6. Phosphorus utilization in broilers fed with diets supplemented with different feed ingredients
ABSTRACT: A reliable determination of endogenous phosphorus (P) excretion is required to measure P utilization in chickens accurately. The objective of this study was to investigate phosphorus (P) retention in broilers fed diets formulated with different feed ingredients. Sixty-four 15-d old broiler chicks were fed diets in which part of the dietary P was pr

7. Serum biochemical profile of neonatal buffalo calves
RESUMO Amostras de sangue de 50 bezerros de búfalo Murrah foram examinados nesse estudo. Os animais foram distribuídos em três grupos de acordo com a paridade de suas genitoras: G1 (n=15) bezerros de búfalas primíparas, G2 (n=19) bezerros de búfalas com 2 a 4 gestações, e G3 (n=16) bezerros de búfalas com cinco ou mais gestações. Amostras de sangu

8. Digital Soil Mapping of Soil Properties in the “Mar de Morros” Environment Using Spectral Data
ABSTRACT Quantification of soil properties is essential for better understanding of the environment and better soil management. The conventional techniques of laboratory analysis are sometimes costly and detrimental to the environment. Thus, development of new techniques for soil analysis that do not generate residues, such as spectroscopy, is increasingly n

9. Response of vegetation to sheep dung addition in a degraded Cerrado area
RESUMO O Cerrado é o segundo maior bioma do Brasil, sendo este um ‘hotspot’ de biodiversidade. A construção de usinas hidrelétricas dá origem a áreas degradadas, muitas vezes desprovidas de vegetação, denominadas “áreas de empréstimo”. Ovinos excretam grande parte dos nutrientes que ingerem, entre eles fósforo, cálcio, potássio, nitrogê

10. Prediction equations for energy values of animal meals obtained using meta-analysis
ABSTRACT The objective of this study was to determine prediction equations to estimate the nitrogen-corrected apparent metabolizable energy (AMEn) values of animal meals used in broiler diets through meta-analysis. A bibliographic review was undertaken with studies conducted in Brazil from 2000 to 2016 to catalogue information on AMEn values and the followin

11. A Multi-Pumping Flow System with Pulsed Fluidization to Evaluate Soil Capacity for Phosphate Adsorption
Soils with high levels of iron and aluminum, thus negatively the phosphorous availability, affecting crop yields. A prior determination of the soil capacity to adsorb phosphate is relevant to attaining good agricultural performance. To this end, a multi-pumping flow system with pulsed fluidization is proposed. The procedure takes into account the amount of r

12. Litterfall and Nutrient Dynamics in a Mature Atlantic Rainforest in Brazil
ABSTRACT We assessed litterfall and nutrient cycling in an old-growth Atlantic rainforest in southern Brazil. Plant litter collected monthly was separated into: leaves, twigs, reproductive organs, and fragments, and dried, weighed, and ground. Determination of carbon, nitrogen, phosphorus, potassium, calcium, magnesium, and sodium contents of different litte
