Objetivou-se com esse estudo ampliar o conhecimento relativo ao efeito dos modelos de maternidade e de aquecimento do abrigo escamoteador para leit?es, utilizando como ferramenta de avalia??o a an?lise de imagem para o entendimento do comportamento animal, avaliar alguns dos ?ndices zoot?cnicos tanto dos leit?es quanto das f?meas que podem ser influenciados pelo ambiente e possibilitar an?lise econ?mica dos modelos. Foram avaliados dois tipos de celas parideiras e dois tipos de escamoteador. O modelo 1 (MOD 1) formado por 8 celas parideiras com piso semi-ripado, e escamoteador de alvenaria, com aquecimento por meio de resist?ncia el?trica embutida no piso e ilumina??o com l?mpada fluorescente de 7 W. O modelo 2 (MOD 2) composto por 8 celas parideiras totalmente ripado de ferro, com o escamoteador de madeira, com o aquecimento por meio de l?mpada incandescente de 60 W. Os dados foram coletados do nascimento at? o 21? dias. O MOD 1 obteve os melhores valores de desempenho para os leit?es. Escamoteadores do MOD 1 obtiveram maiores percentuais de temperaturas dentro do conforto t?rmico em rela??o ao MOD 2, apesar dos elevados percentuais de temperatura abaixo do conforto. A temperatura do piso do MOD 1 obteve maiores percentuais de valores dentro do conforto t?rmico em todas as semanas do per?odos experimental. A temperatura do piso das celas no MOD 1 foi mais elevadas em rela??o ao MOD 2. A higiene das celas n?o foi afetada diretamente pela estrutura da cela e sim por altera??es no manejo, como arra?oamento em hor?rio diferente do habitual. A mortalidade, onfalite, artrite e les?es nos joelhos dos leit?es n?o apresentaram diferen?a significativa ente os modelos (p< 0,05). O modelo 1 apresentou um lucro superior ao modelo 2, de aproximadamente R$ 1,37 por leitegada, sendo necess?rio avaliar o gasto com m?o de obra para inferir qual o modelo ? mais rent?vel para o produtor. / Disserta??o (Mestrado) ? Programa de P?s-Gradua??o em Zootecnia, Universidade Federal dos Vales do Jequitinhonha e Mucuri, 2010. / ABSTRACT One of the main problems relating to thermal comfort and animal welfare in pig farming is in maternity, which have two different environments with very different requirements to be evaluated. This study aimed to expand the knowledge on the effect of the systems to maternity and heating of creep for piglets using the image analysis as evaluation tool to understand animal behavior, to evaluate some of the indexes of both piglets and the females considering that it can be influenced by environment and allow an economic analysis of this systems. There were evaluated two types of dam cells and two types of creep. The model 1 (MOD 1) was formed by 8 dam cells with semi-slatted floor and creep of masonry, with electrical resistance built into the floor and illumination with fluorescent lamp of 7 W. The model 2 (MOD 2) consisted of eight dam cells with totally ripped iron, with the creep of wood for heating by incandescent lamp of 60W. Data were collected from birth until weaning at 21 days. The MOD 1 showed the best performance values for piglets. The temperature of the creep of MOD 1 showed the highest percentage of temperatures within the thermal comfort in relation to MOD 2, despite the high percentage of temperature below comfort. The temperature of the floor of MOD 1 showed the highest percentage of values within the thermal comfort in every week of the experimental period. The temperature of the surface of the cells in MOD 1 were higher compared to the MOD 2, but not enough to cause thermal discomfort for the sows. The hygiene of the cells was not affected directly by the structure of the cell but rather by changes in handling practices such as feeding on different time than usual. Mortality, omphalitis, arthritis and knee injuries of the piglets showed no significant differences between the systems (p<0.05). The use of the system with creep with heated floors (MOD 1) showed a profit above the heating system with a light bulb (MOD 2) of approximately R$ 1,37 for litter, being necessary the evaluation of the expends to infer about the most financially profitable system for the producer.
