Resumo: | Swine facilities in tropical climates, especially the maternity, have worked with typological systems that have been little studied to determine the influence of the type of farrowing on microenvironmental conditions and its effect on both the sows and the piglets' physiological parameters. Therefore, the aim of the research was evaluate the thermal environment (Temperature Humidity Index - THI and Radiant Thermal Load - RTL) and its influence on some physiological parameters (respiratory frequency - RF and rectal temperature - TRectal) in the sows and piglets in two different types of farrowing systems (Traditional and Slatted), in a typological swine facility located in tropical climates in Colombia. The findings showed that in the two systems, both for sows and piglets, the type of farrowing system did not generate significant differences in the physiological responses RF and TRectal. Also, the RTL did not show significant differences in the two types of farrowing system at the piglets and the sows’ level, without exceeding the maximum allowed levels. Temperature-Humidity Index was above the threshold during all experimental time, being slightly higher at the piglets' level with Slatted systems. These results show that the type of floor has little impact on the conditions of animal thermal comfort at the sows and piglets’ level. However, variables like low-temperature, low radiant energy exchange, and high humidity, which were found mainly at the piglets’ level, could have the highest incidence for not achieving a suitable microenvironment. This means that almost all Colombian pig farming facilities require a redesign of their farrowing system to guarantee better thermal conditions for both piglets and sows. |
