Uso da zootecnia de precisão na avaliação do comportamento de leitões lactentes submetidos a diferentes sistemas de aquecimento

Abstract: RESUMO -Objetivou-se, nesta pesquisa, avaliar o comportamento de leitões em diferentes sistemas de aquecimento, por meio de análise de imagem e identificação eletrônica, na sala da maternidade, com 80 animais entre o nascimento e o desmame. Os tratamentos adotados para avaliação da eficiência dos diferentes sistemas de aquecimento foram: piso térmico, lâmpada incandescente, resistência elétrica e lâmpada de infravermelho. O delineamento experimental foi em blocos casualizados com quatro tratamentos e 18 blocos… Show more

“…results, it is evident that improvement in heating systems is required to maintain the thermal comfort conditions within the creep feeder housing. Silva et al (2005), when evaluating the behavior of piglets in different maternity warming systems, mention that in relation to the infrared lamp, the Tbs data inside the shelter were, on average, always above the ideal condition, throughout all experimental phases.…”

“…The radiant heat energy of the heated floors in the SASA, SASC and SAEL treatments was not sufficient to promote the reduction of RH inside the creep feeder's shelter, presenting values close to the RH of the maternity ward. welfare, there is a need for individualized attention to the piglets, in order to protect them from exposure to temperatures outside their comfort range, which means investing in low-cost and high efficiency heating systems (SILVA et al, 2005).…”

“…Como a frequência de acesso ao escamoteador está diretamente relacionada à variação de temperatura do ambiente, esse fato pode ser atribuído a menores temperaturas do microambiente encontrado nas celas de alvenaria (Tabela 1). Esses resultados corroboram aqueles obtidos por SILVA et al (2005), que, ao estudarem diferentes fontes de aquecimento nos abrigos escamoteadores, verificaram que reduções da temperatura ambiente nas salas de maternidade levaram ao aumento na procura por fonte artificial de calor.…”
