Abstract: In order to overccome the drawbacks of traditional one, experiments were carried out to design and make two new types of piglet electric heating panels. Application effects in practice were examined. This new one had a dimension of 600 mm×800 mm, and was 30 mm in thickness. Its outer cover was made up of Fiberglass Reinforced Plastics(FRP). The electro-thermal films and the electro-thermal lines that had rated power of 80 W and 90 W respectively, became the heating materials of the new-type piglet electric heating panel. The regulating power switch was a dimmer. The changes of temperature were discovered at the different power levels in the lab. Then, application effects in practice were preliminarily proved. The results indicated that under the conditions of this study, the two types of piglet electric heating panels had significant advantages in power regulation, and so, piglets felt very comfortable for them selves, which meant the increase of piglet lying time in hovers. Moreover, the two new types of piglet electric heating panels improved the welfare and health of piglets. Under the four different conditions designed in this study, new-type piglet electric heating panel Ⅰ, Ⅱ, the traditional type of piglet electric heating panel, and an infrared ray lamp 250 W, the survival rates of weaning piglets were 98.53%, 95.71%, 92.65% and 84.29%, respectively. The mortality rates of diarrhoea of piglet were 1.47%, 2.66%, 5.88% and 12.86%, respectively.
