[Tolerance levels of growing swine for nonoptimal temperatures and their effect on swine production in the tropics (literature study)].

Abstract

The components of the thermohygric complex (air temperature, humidity, and speed) affect directly and indirectly pig production in the tropics. The indirect climatic influence is determined by climatic specifics of pig management and nutrition, especially by the available foodstuff. International findings are presented on the problems of the direct influence on pig production performance by the thermal stress on piglets, young and fattening pigs in tropical locations. This is intended to meet the demand for effectivating pig production in the tropics through improving the microclimatic rearing conditions and abolishing or reducing the thermal stress for the pigs in tropical production locations.
