[Comparative studies of climatic conditions and the effect of climate in the Socialist Republic of Vietnam and in the People's Republic of Bulgaria on the microclimate in housing for commercial poultry breeding].

Comparative studies were carried out on the climate aspects in the Socialist Republic of Vietnam and the People's Republic of Bulgaria. Tested was the effect of the typical tropic and the typical continental climate in buildings for the industrial raising of birds. Data were provided of the solar radiation and the temperature and moisture characteristics of the climate in the two countries. On the basis of these studies and the results obtained in the raising of broilers concrete suggestions were made to optimize the technology of bird raising in Vietnam.

[Microclimate and air composition in a closed chamber meant for the study of the toxicity of atmospheric pollutants for the piglet].

An experimental model representing the pollution background in a pigpen was constructed in order to study the toxicology of pig respiratory air pollutants. Temperature, relative humidity, air-flow rate, total dust, total viable particles, endotoxins in respirable dust (< 5 microns) and ammonia were measured in a 1.9 m3 environmental chamber designed for piglets. The activity of 1 piglet was recorded on video. Temperature and relative humidity were respectively 23.9 +/- 1.3 degrees C and 70.5 +/- 8.3% (mean +/- SD). Air flow rate was 10 m3/h. Dust, viable particles, endotoxin and ammonia concentrations were respectively 7 +/- 2 particles/ml, 3.4 x 10(4) +/- 2.9 x 10(4) BCFP (bacterial colony-forming particles)/m3, 4.8 +/- 1.5 ng/m3 and 6 +/- 0.8 ppm (mean +/- SD). All these parameters were comparable to the lowest values recorded in pigpens.
