1. Influência do sistema de criação em piso sobre cama e gaiola sobre as características ósseas e a qualidade físico-química e microbiológica de ovos de galinhas
RESUMO O experimento foi realizado no setor de avicultura/UFRRJ, utilizando 348 galinhas semipesadas (linhagem Dekalb Brown), com 52 semanas de idade, criadas sob dois sistemas de produção: cage-free e em gaiolas. Os dados obtidos pela análise físico-química e microbiológica dos ovos e a resistência óssea à quebra foram submetidos à análise de var

2. Banana leaf in the diet of laying hens in cage free system
ABSTRACT. The aim of this research was evaluate the productive performance, egg quality and the endoparasites presence on Carijó laying hens in Cage Free system, fed with two experimental diets, one of them supplemented with fresh banana leaf in natura. It were used 196 laying hens with twenty-four weeks of age, distributed in a completely randomized design

3. Performance and welfare of different genetic groups of laying hen
ABSTRACT. The objective was to evaluate the performance, egg quality, thermoregulation, body morphology and behavior of different categories of laying poultry. Two treatments with two genetic groups were used, 50 birds of the Hisex Brown strain and 50 birds of the Black Avifran chicken breed with 55 weeks, distributed in a completely randomized design with 1

4. Seletividade alimentar de galinhas poedeiras submetidas a diferentes métodos de debicagem em dois sistemas de criação
RESUMO: O presente trabalho foi conduzido para avaliar se diferentes métodos de debicagem e sistemas de criação afetam a seletividade alimentar de galinhas poedeiras. Foram utilizadas 178 aves na fase de recria e 120 aves na fase de produção, da linhagem Hy-line Brown, divididas em um delineamento experimental em esquema fatorial (2x3), com dois sistem

5. Evaluation of Meat and Egg Traits of Beijing-you Chickens Rotationally Grazing on Chicory Pasture in a Chestnut Forest
ABSTRACT Barn and cage-fed chickens have presented several problems, such as high rates of infectious disease and consequent antibiotic abuse, poorer chicken health and welfare, and often poorer meat and egg quality compared with free-range chickens. The poultry agroforestry system is becoming increasingly popular in many poultry farms nowadays. In this stud

6. Immobilization and therapeutic passive stretching generate thickening and increase the expression of laminin and dystrophin in skeletal muscle
Extracellular matrix and costamere proteins transmit the concentric, isometric, and eccentric forces produced by active muscle contraction. The expression of these proteins after application of passive tension stimuli to muscle remains unknown. This study investigated the expression of laminin and dystrophin in the soleus muscle of rats immobilized with the

7. Influence of food restriction on lipid profile and spontaneous glucose levels in male rats subjected to paradoxical sleep deprivation
OBJECTIVES: The purpose of this study was to determine the paired consequences of food restriction and paradoxical sleep deprivation on lipid profile and spontaneous glucose levels in male rats. METHOD: Food restriction began at weaning, with 6 g of food being provided per day, which was subsequently increased by 1 g per week until reaching 15 g per day by t

8. Influence of trichomes on attractiveness and ovipositional preference of Bemisia tabaci (Genn.) B biotype (Hemiptera: Aleyrodidae) on tomato genotypes
Brazil is one of the world's largest tomato producer, but considerable part of the production is lost due to the attack of Bemisia tabaci (Genn.) B biotype. Resistant germoplasm plants can be an important method for B. tabaci control in integrated pest management approaches. The attractiveness and ovipositional preference of B. tabaci for 17 tomato genotypes

9. Radio frequency electromagnetic radiation (RF-EMR) from GSM (0.9/1.8GHz) mobile phones induces oxidative stress and reduces sperm motility in rats
INTRODUCTION: Mobile phones have become indispensable in the daily lives of men and women around the globe. As cell phone use has become more widespread, concerns have mounted regarding the potentially harmful effects of RF-EMR from these devices. OBJECTIVE: The present study was designed to evaluate the effects of RF-EMR from mobile phones on free radical m

10. Expressão do Coativador-1 do Peroxisome Proliferator-Activated Receptor- (PGC-1) em fígado e músculos esqueléticos soleus e plantaris de ratos machos Wistar submetidos ao exercício físico voluntário crônico / Peroxisome Proliferator-Activated Receptor- - Coactivator-1 ( PGC-1 ) expression in the liver and skeletal muscles soleus and plantaris of male Wistar rats subjected to chronic voluntary exercise
INTRODUCTION: The Peroxisome Proliferator-Activated Receptor- - Coactivator 1 ( PGC-1 e ) is a protein responsible for the connection between environmental stimuli and cell metabolic response. Its presence is important in fat tissue, hepatic and skeletal muscle and in animals on brown fat tissue. Interact with nuclear receptors modulating the mitochondrial b

11. Resfriamento do piso da maternidade para porcas em lactação no verão / Floor cooling in farrowing room to lactating sows in the summer
This study was realized to evaluate the effect of cooling the cage floor under the lactating sows on productive performance receiving different amounts of feed in the summer. Forty two sows with different parturition orders were used (1 to 5), distributed in three treatments (floor not cooled and free intake; floor cooled and 5,5 kg/day of intake; floor cool

12. Detecção condutométrica sem contato: uma nova ferramenta para monitoramento de interações biomoleculares em microssistemas analíticos / Contactless conductivity detection: a new tool for monitoring biomolecular interactions on analytical microsystems
The study reported in this thesis shows the application of a capacitively coupled contactless conductivity detection (C4D) for monitoring biomolecular interactions on analytical microsystems. Initially, the analytical performance of the microsystems fabricated in glass, poly(dimethylsiloxane) (PDMS) and polyester-toner (PT) was investigated in order to choos
