Os objetivos deste estudo foram modelar e avaliar, pelo uso da lógica fuzzy, a sensação de conforto térmico animais confinados em função das variáveis fisiológicas temperatura retal (TR) frequência respiratória (FR), determinando os intervalos críticos dessas variáveis. O banco dados foi formado dois ambientes distintos: clima subtropical (Município São Pedro, Brasil) mediterrâneo Évora, Portugal). Para formação do fisiológicos, obtidos TR FR vacas holandesas. análise física ambiente,...
O presente estudo avaliou a eficiencia termica de diferentes sistemas arrefecimento evaporativo; aspersao (TA) e nebulizacao (TN), conjugados com ventilacao forcada, quanto melhoria do microclima interior das instalacoes na resposta produtiva dos animais. foi realizado numa vacaria em sistema estabulacao livre localizada no Sao Paulo/Brasil, tendo sido utilizado 10 animais da raca Holstein Freisian por tratamento. A recolha dados efectuou-se, durante 21 dias consecutivos. No recolheram-se os...
The objective of this study was to evaluate the thermal comfort growing and finishing pigs affected by different constructive typologies installations regarding floor lateral partitions.Were evaluated following pen types: with water pit, partially slotted on sides, sides in center facilities.The variables were measured: dry bulb temperature, black globe relative humidity, air velocity.Based these data, temperature humidity index, index specific enthalpy calculated.The a pit showed higher...
ABSTRACTThe objective of this study was to evaluate programs supplementary lighting for calves in individual shelters with different roof materials, as a strategy stimulate concentrate consumption and the reduction milk feeding period increase financial viability. Twenty seven dairy crossed Holstein × Gir female were randomly distributed three roofing materials (cement fiber tile, recycled tile thatched roofs), associated light duration (12, 16 20 h) repetitions. The experimental design...
O objetivo do trabalho foi desenvolver e testar um modelo matemático computacional, com base na teoria dos conjuntos fuzzy, para predizer a temperatura superficial frequência respiratória de suínos em função da idade animais o índice umidade (ITU). Foram observados fase crescimento terminação. Os dados ambiente térmico (ITU) respostas fisiológicas (Temperatura Superficial (TS) Frequência Respiratória (FR)) foram usados no desenvolvimento sendo definidas, como variáveis entrada (dias) (ITU),...
Animal welfare is conditional on well-planned and well-managed exploitation, since the management of animals strongly influences their behavior, productivity and, consequently, yield quality final product. In this study, an investigative review was carried out literature, governmental databases main institutions relating to animal welfare, seeking highlight discuss differences in legislation between Brazil Portugal, view interest concern scientific community consumer market relation methods...
Ventilation is one of the most important tools for controlling greenhouse climate, influencing environmental conditions such as temperature, humidity and carbon dioxide concentration, which affect development production crop.Natural ventilation result action two natural forces, wind thermal buoyancy.The main objectives this study were to: 1).compare behaviour internal air parameters temperature in a with different management 2).calibrate validate climatic model.The was based on experiments...
This study addresses the issue of domestic violence against women, highlighting role shelters in Amazonas as essential instruments breaking cycle violence. The general objective is to analyse how these institutions contribute protection and recovery victims, providing comprehensive support that promotes their autonomy security. methodology applied based on a theoretical practical analysis functioning shelters, assessing legislative aspects application state Amazonas. research reveals...
Air quality is one of the main factors that must be guaranteed in animal production. However, measurement pollutants still a problem several countries because available methods are costly and do not always apply to reality constructive typology adopted, as with hot climate, which adopt predominantly open facilities. Thus, objective present study was develop predictive models for potential generation emission ammonia production broiler chickens different types litter, reuse cycles under...
ABSTRACT: This research aimed to assess Girolando calves’ concentrate intake and performance when placed in shelters with distinct roofing materials programs of supplementary lighting during the milk-feeding stage. In order so, we used a completely randomized design 3×3 factorial arrangement, three replications. Females calves (n=27) were assigned individual at random 3 different (fiber cement tile, recycled tile thatched roofs) subjected (12, 16 20 hours). No interaction was observed...

The main goal of the AWARTECH project (Animal Welfare Adjusted Real Time Environmental Conditions Housing) was to develop an innovative precision livestock tool that will support and reinforce pig value chain, through management solutions based on monitoring, analysis control environmental, physiological, behaviour animal performances parameters. data collected by sensors temperature, relative humidity, air velocity gas concentration, which are integrated in environmental system (Webisense)...
The objective of this study was to evaluate the effect thermal environment on milk during year 2004. experiment carried in free stall Center Studies and Experimentation Mitra. For evaluation productions were used 9 animals Holstein Frisian breed. analysis Index Temperature Humidity (THI). data through by ANOVA using itself Tukey means comparisons test. THI values observed June, July August months (with higher air temperatures) included dangers class September alerts class. these has...
The sustainable agriculture concept emerges from the necessity to ensure food production feed human growing population, while natural resources, water and soil quality, ecosystems others are preserved. One way implement know-how techniques in is through educational courses universities, such as MSc programme, by promoting communication between academics, researchers, agricultural workers other experts. This paper examines best practices serve a guide develop programme Sustainable Farming. A...
