“…However, these companies mostly, do not record the electricity consumption of their equipment which according to Mosko et al (2010) constitutes a significant part of the production cost of an industry making necessary to study the quality of supply and the consumption (Turco et al, 2002). The scaling of energy transformers and motors in relation to the equipment must be considered in the production sectors, since when inadequate, it leads to power supply failures and variation in the internal environment in a same shed with acclimatization system (Bueno & Rossi, 2006;Silva et al, 2013).…”

ABSTRACT:The objective of this study was to compare the performance of laying hens between automated aviaries, one with and another without acclimatized system. On a daily basis it was registered in each aviary the mortality, the egg production, and the feed consumption. The variables of the dry bulb temperature, relative humidity and black globe temperature were registered every 30 minutes using the thermos hygrometer. Every 28 days ninety eggs from each aviary were collected randomly and the variables egg weight, shell weight, shell thickness and Haugh Unit were registered. The consumption and quality of the electrical energy supply were monitored every 30 minutes using registers of electrical magnitude. The results showed that the acclimatization system consumes more electrical energy; however it provides thermal environment more suitable for bird raising, resulting in better production and quality of the eggs. The quality of the electrical energy supply was not maintained, since several interruptions occurred which resulted in higher mortality in the acclimatized aviary. It was concluded that the acclimatization system is technically feasible, since the electrical energy supply is guaranteed.

“…The thermal environment can be classified according to comfort indexes, allowing determining if the environment is adequate to desired animal production activity (Conceição et al, 2008). According to Bueno & Rossi (2006), the success or failure of broiler production is directly linked to the environmental conditions to which they are submitted. Randón et al (2004) assert that the essential parameters of the facilities microclimate are air temperature, air relative humidity, and litter moisture.…”

This study was conducted with the objective of evaluating the use of concrete or hard-packed dirt floor in broiler houses. This experiment was carried out in two different phases. The following performance parameters were studied: live weight, feed intake, feed conversion ratio, and mortality. Litter moisture, pH and temperature were measured. Litter residual contamination after cleaning and disinfection was also evaluated. A dry bulb thermometer, a wet bulb thermometer, and a black bulb thermometer were placed inside each broiler house at bird height and outside the broiler house for data collection. Environmental data were collected at 3h intervals from 00:00 to 24:00 hours during weeks 4, 5, and 6 of the grow-out. Based on the collected data, air relative humidity (RH) was determined, after which wet bulb globe temperature (WBGT) and Radiant Heat Load (RHL) were calculated. There were no differences in live performance parameters. However, total mortality and sudden death were higher in birds raised on dirt floor. On days 0, 14 and 35, litter pH was higher in the dirt floor as compared to the concrete floor, but at the end of the grow-out, this difference disappeared. There was a cubic effect of bird age on litter moisture, which increased up to day 28, and then stabilized or decreased. Litter coliform contamination was higher at the end of the grow-out as compared to that found at housing, but it was not influenced by floor type. The general thermal comfort of broiler raised on dirt floor was similar to that of broilers raised on concrete floor.

R E S U M OO uso racional de energia elétrica em creches suínas pode ser viabilizado sem afetar o desempenho produtivo dos animais visando à sustentabilidade do setor razão por que o objetivo deste trabalho foi avaliar a eficiência de duas tecnologias de controle de temperatura em sistema de aquecimento resistivo em creche suína, no uso de energia elétrica e no ganho de peso dos leitões. Os sistemas avaliados foram: resistências elétricas suspensas com controle PID (proporcional, integral e derivativo) e resistências elétricas suspensas com termostato. O experimento foi realizado durante o período de inverno, entre maio e setembro de 2013. Os critérios de comparação foram: consumo de energia elétrica (kWh), consumo específico (kWh kg ). O sistema de aquecimento com controlador PID, apesar de apresentar maior consumo médio, foi mais eficiente quanto ao uso de energia elétrica para produzir 1 kg de peso vivo (2,88 kWh kg Use of PID controller as efficient technology in heating system of swine nursery A B S T R A C TThe rational use of energy in swine nurseries can be made possible without affecting the productive performance of animals, aiming the sustainability of the sector. The objective of this study was to evaluate the efficiency of two technologies for temperature control of resistive heating system for swine nursery on the use of electricity by the systems and on the weight gain of the piglets. The evaluated systems were: overhead electric heaters with PID (proportional, integral and derivative) control and suspended electric heaters with thermostat. The experiment was conducted during the winter period between May and September 2013. The comparison criteria were: electricity consumption (kWh), specific consumption (kWh kg ). The heating system with PID controller, although showed a higher average consumption, was more efficient as the electricity used to produce 1 kg of body weight (2,88 kWh kg ) and for weight gain of piglets (7,3 kg) compared to the system with thermostat (3,98 kWh kg -1 , 1,03 R$ kg -1 and 5,2 kg, respectively).
