1. Características do trato digestivo, metabolizabilidade e retenção de nutrientes em frangos de corte alimentados com complexo enzimático
ABSTRACT The objective was to evaluate the digestive tract characteristics, metabolizability and nutrient retention of broilers fed diets supplemented with enzyme complex (EC). To evaluate the characteristics of the digestive tract 600 female Cobb 500 birds were used, distributed in a completely randomized design, with 5 inclusion levels of the EC (0; 100, 2

2. POLYETHERIMIDE/POLYVINYLPYRROLIDONE HOLLOW-FIBER MEMBRANES FOR USE IN HEMODIALYSIS
Abstract In this study, polyetherimide/polyvinylpyrrolidone (PEI/PVP) hollow fiber membranes (HFMs) were synthesized by the phase inversion method. The synthesized PEI/PVP membranes were characterized by morphological analysis and transport properties (hydraulic permeability and solute rejection coefficient). Their performance in uremic solutes separation wa

3. Stabilization of Rice Bran in Broiler Feed with Natural and Synthetic Antioxidants and Heat Treatment
ABSTRACT The objective of this study was to evaluate different strategies for the oxidative stabilization of rice bran (RB) in the diet of broiler chickens using natural antioxidant additives, synthetic antioxidant additives and heat treatment on performance, breast meat quality and liver fat content and the nutrient digestibility coefficients. Furthermore,

4. Red clover silage: an alternative for mitigating the impact of nitrogen excretion in ovine production systems
ABSTRACT The objective was to quantify the flow of intestinal nutrients and nitrogen excretion and retention in sheep receiving isoproteic diets. Eight Texel x Lacaune wethers (average body weight = 25±2.5 kg) were fitted with duodenal cannula and housed in metabolic cages. Wethers were assigned to the treatments in a crossover design with two periods of 20

5. SPRAY RETENTION ON COFFEE LEAVES ASSOCIATED WITH TYPE AND CONCENTRATION OF ADJUVANTS
ABSTRACT Agricultural spray adjuvants (ASA) are widely used in pesticide applications to enhance the performance of pesticides. The aim of this research was to investigate the effects of ASA on static surface tension (SST) and foliar spray retention on coffee leaves. The SST of ASA at different concentrations was determined by the drop weight method. Spray r

6. Controlled release fertilizer encapsulated by a κ-carrageenan hydrogel
Abstract The release kinetics of nitrogen and phosphorous of a granulated fertilizer, encapsulated in a κ-carrageenan-based hydrogel (CBH), was evaluated in order to determine its release mechanism given the potential this hydrogel has as coating material for controlled release fertilizers (CFRs). The effect of pH on the release properties was also investig

7. Growth of tomato seedlings in substrates containing a nanocomposite hydrogel with calcium montmorillonite (NC-MMt)
RESUMO O uso correto de hidrogéis em determinadas situações pode aumentar as taxas de sobrevivência das plântulas, seu crescimento e a capacidade de retenção de água do meio de cultivo. Uma técnica para a produção de um hidrogel nanocompósito usando montmorilonita de cálcio (NC-MMt) foi desenvolvida recentemente. No entanto, resultados da pesqui

8. Poultry by-product meal as dietary protein source for dourado, Salminus brasiliensis: an economic appraisal
ABSTRACT: The dourado, Salminus brasiliensis, a large, carnivorous, Neotropical, Characin, is highly regarded for fish farming and sport fishing alike. However, studies on the farming and husbandry of dourado are still scarce. This study evaluated the performance of dourado fed diets formulated so as to contain increasing levels of poultry by-product meal as

11. Calcium particle size and feeding time influence egg shell quality in laying hens
ABSTRACT. An experiment with Leghorn laying hens was undertaken to determine the effect of oyster shell particle size and feeding time on different production variables, calcium retention, plasma calcium content and egg internal and external quality. Two hundred Leghorn layers (40 weeks old old) were allocated in five dietary treatments with four replicates

12. Development of a preservative for white fresh cheese from the addition of Peruvian Tara gum Caesalpinia spinosa
Abstract Over the time, fresh cheese undergoes changes in its physicochemical and sensorial properties, mostly associated to the loss of moisture, which directly affects the texture and yield. In this sutdy, we elaborated an alternative formulation for the preparation of cheese with Peruvian tara gum Caesalpinia spinosa, for moisture retention increasing, w
