“…The sleeping behavior at the back of the pen indicates that the animals are seeking a damp location in which to lie. In environments that induce heat stress, pigs employ a strategy of dampening their body surface to promote thermoregulation (BARBARI; CONTI, 2009;BRACKE, 2011).…”

This work was conducted to assess behavioral, thermoregulatory and operational aspects of gilt breeding (Body weight, 25-110 kg) whilst the animals were housed in 2-cm deep shallow pool pens (SPP), without the addition of water, compared to the use of fully compact floor pens (TSF) during the winter and summer seasons. Commercial female strains for high lean tissue accretion were used, housed in grower/finisher pens for 108 days (11 animals/pen, 1.2 m 2 /animal). Instantaneous observations of behavior were carried out every 12 min between 7:00 and 19:00 hours throughout the six days of the raising period. At the end of the raising period, the operational aspects of cleaning the facilities were analyzed. A 2 × 2 factorial scheme design was used, with two types of floors and two seasons, with three replicates. The average temperatures in winter and summer were 19.9 ± 2.2°C and 24.5 ± 2.3°C, respectively. The use of SPP reduced aggressive behavior and increased exploratory behavior, increased the time for the daily cleaning, and reduced the time for the final cleaning of the pens.

Foram utilizadas fêmeas de linhagem comercial para alta deposição de tecido magro, alojadas em baias de crescimento/terminação por 108 dias (11 animais por baia, 1,2 m 2 /animal). Foram realizadas observações instantâneas do comportamento, a cada 12 minutos, das 7h00min às 19h00min por seis dias ao longo do período de criação. No final do período de criação foram analisados os aspectos operacionais da limpeza das instalações. Foi utilizado delineamento em um esquema fatorial 2x2, com dois tipos de pisos e duas estações, com três repetições. As temperaturas médias do ar no inverno e verão foram de 19,9±2,2ºC e 24,5±2,3ºC, respectivamente. A utilização de LDR reduziu os comportamentos agressivos e aumentou os comportamentos exploratórios, aumentou o tempo de limpeza diário e reduziu o tempo de limpeza final das baias.

“…For that purpose, there are systems of forced ventilation using fans (TOLON & NÄÄS, 2005), evaporative snout cooling system (TOLON & NÄÄS, 2005) and also with drip systems (BARBARI & CONTI, 2009). However, the information concerning the performance of sows from different parities, when exposed to these systems, is scarce in regions of subtropical climate.…”

The aim of the study was to evaluate the influence of different temperature control systems on the voluntary feed intake (VFI), percentage of weight loss (PWL) and performance of lactating sows as well as on the weight of their piglets. Two systems were used: traditional temperature control system (TTCS) with curtain management and an evaporative snout cooling system (ESCS RESUMO O objetivo do estudo foi avaliar a influência de diferentes sistemas de controle de temperatura sobre o consumo voluntário de ração (VFI), porcentagem de peso perdido (PWL) e desempenho de fêmeas lactantes e de suas leitegadas. Dois sistemas foram utilizados no estudo: o sistema tradicional de controle de temperatura (TTCS), com manejo de cortina e o sistema de resfriamento adiabático evaporativo (ESCS). O estudo foi realizado no verão de 2011. Após o parto e ao desmame, 241 fêmeas foram pesadas e foi avaliado o PWL durante a lactação. Fêmeas TTCS perderam mais peso (5,3±0,9%; P<0,05) do que as fêmeas ESCS (2,2±0,9%). VFI foi medido em intervalos de quatro dias em 32 fêmeas primíparas e 39 multíparas. Fêmeas ESCS tiveram maior VFI (5,8±0,2kg -1 dia; P<0,05) do que fêmeas TTCS (4,8±0,2 kg dia -1 ). Primíparas (4,4±0,2kg dia -1 ) tiveram menor VFI

“…In the current study, the THI increased 2.37 under clay tile (average 79) and 3.37 under fiber cement tile (average 82) during the studied stages. BARBARI & CONTI (2009) suggest that producers should have special care with THI values above 75 and within the range of 79 to 83 that represents a critical condition for pigs. Following the recommendation in this past study by BARBARI & CONTI (2009), sows and piglets are thermally uncomfortable in both rooms (clay and fiber-cement tiles), and this condition is critical to pig production.…”

ABSTRACT:The global animal production is increasing as expected to meet world demand for food, especially for meat products. This research aimed to investigate the effect of two types of roofs (clay and fiber-cement tiles) in a tropical area on the thermal comfort of farrowing sows and piglets. Twelve sows and forty-eight piglets were observed during summer in the Southeast region of Brazil. Climate variables, thermal comfort and surface temperature (sows and piglets) were assessed. The type of roofs clearly affected the piglets' surface temperature during all studied periods, but the results were not similar in the sows' surface temperature. Temperature and humidity index found was high in the building with fiber-cement tiles. The pen location in the housing also influenced the piglet surface temperature. Controlling temperature fluctuation in piglet housing is crucial; therefore, providing adequate rearing environment in tropical condition might help pig productivity as well as farmer profitability.
