13. Broiler-Housing Conditions Affect the Performance
ABSTRACT In the last decades animal production has considerably increased worldwide to sustain an ever-growing human population. Among animal reared for consumption purposes, chickens are undoubtedly one of the most successful, mainly due to their rapid growth rate. The development of broiler farming has been accompanied in recent years by a substantial atte

14. A new approach to feed frequency studies and protein intake regulation in juvenile pirarucu
ABSTRACT This study aimed to investigate pirarucu's (Arapaima gigas) ability to trigger a self-feeding system to regulate protein intake between two standard diets that contained 39% and 49% of crude protein. The same system allowed the evaluation of daily feeding and locomotor activity rhythms. Eighteen fish (654.44±26.85g) were distributed into six 250 L

15. Photogrammetry: a Non-Invasive and Objective Method for Detecting Locomotion Problems in Broiler Chickens
ABSTRACT Locomotion problems in broiler chickens can cause economic losses of up to 40% of the total revenues due to carcass condemnation and downgrading at processing. Leg disorders, such as femoral lesions, tibial dyschondroplasia, and spondylolisthesis, substantially impact the welfare of chickens as these disorders can prevent birds from reaching the fee

16. Performance, rumen development, and carcass traits of male calves fed starter concentrate with crude glycerin
ABSTRACT The objective of this study was to assess the effects of including crude glycerin in the diet on intake, performance, rumen development, and carcass traits of dairy crossbred veal calves fed starter concentrate containing 0, 80, 160, and 240 g kg−1 crude glycerin. Twenty-eight calves with an average weight of 38.03±6.7 kg and five days of age wer

17. CLASSIFICATION OF POWER QUALITY CONSIDERING VOLTAGE SAGS IN DISTRIBUTION SYSTEMS USING KDD PROCESS
In this paper, we propose a methodology to classify Power Quality (PQ) in distribution systems based on voltage sags. The methodology uses the KDD process (Knowledge Discovery in Databases) in order to establish a quality level to be printed in labels. The methodology was applied to feeders on a substation located in Curitiba, Paraná, Brazil, considering at

18. Feeding behaviour of broiler chickens: a review on the biomechanical characteristics
Feed related costs are the main drivers of profitability of commercial poultry farms, and good nutrition is mainly responsible for the exceptional growth rate responses of current poultry species. So far, most research on the poultry feeding behaviour addresses the productivity indices and birds' physiological responses, but few studies have considered the b

19. ANISOTROPIC DIELECTRIC CORRUGATED CYLINDRICAL GUIDE / GUIA CILÍNDRICO CORRUGADO COM DIELÉTRICO ANISOTRÓPICO
Esta tese apresenta uma análise de uma estrutura de corneta cônica corrugada com dielétrico anisotrópico, com eixo óptico na direção axial da corneta. Esta configuração de corneta pode ser conseguida utilizando-se a estrutura de uma corneta corrugada com a adição de um cone dielétrico anisotrópico uniaxial. A anisotropia pode ser conseguida arti

20. Sistema inteligente para alocação eficiente de dispositivos indicadores de falta em alimentadores de distribuição / An intelligent system for efficient allocation of fault indicators in distribution feeders
Fault Indicator (FIs) devices have contributed to improve the location of faults on primary feeders, and consequently the reliability of distribution systems. However, one of the main problems facing their installation in a large scale in a distribution system is the lack of efficient methods to analyze big networks and to pinpoint exactly on which buses the

21. Os Nematoda da plataforma continental ao largo do sistema estuarino de Santos / Nematoda of the continental shelf off Santos estuarine system
To assess the influence of Santos estuarine system on the nematodes of the adjacent continental shelf, the density, composition and generic diversity of this group were analyzed and related to the sediment type, organic matter content and phytopigments biomass. The sediment was collected at six stations, in the winter of 2005 and summer of 2006, with a box-c

22. Características da carcaça e da carne de novilhos de origem leiteira alimentados com dietas à base de palma forrageira. / Carcass and meat characteristics of dairy steers fed based on spineless cactus.
The objective of this issue was to evaluate the quantitative and qualitative characteristics of the carcass of dairy steers receiving diets based on spineless cactus and sorghum silage; the silage is associated by cottonseed meal, and the use of ultrasound to evaluate carcass of Holstein-Zebu young cattle destined for slaughter. The study was conducted at th

23. Trophic interactions among sympatric zooplanktivorous fish species in volume change conditions in a large, shallow, tropical lake
Significant reductions in the water volume of shallow lakes impose a restriction on species segregation promoting more interactions in the trophic relationships. The diets of three closely related zooplanktivorous silversides belonging to the Atherinopsidae species flock of lake Chapala , Mexico, were analyzed at two sites (Chirostoma jordani, C. labarcae, a

24. Termites as Bioindicators of Habitat Quality in the Caatinga, Brazil: Is There Agreement Between Structural Habitat Variables and the Sampled Assemblages?
The composition of termite assemblages was analyzed in three caatinga sites of the Estação Ecológica do Seridó, located in the municipality of Serra Negra do Norte, in the state of Rio Grande do Norte, Brazil. These sites have been subjected to selective logging, and cleared for pasture and farming. A standardized sampling protocol for termite assemblage
