title: [Evaluation of abiotic ecological factors and their dynamics at various densities in raising broilers].
abstract: Three productional experiments were carried out in which the broilers were kept on unified premises under one and the same technology, but at various densities of raising: 14.4 and 23.4/sq. m., and 16.6 and 23.6/sq. m. with the second and third experiment. The dynamic, light intensity, and content of toxic gases along with the homogenization of air in the birds' vital zone were followed up. Differences were established which were defined by the higher density of raising, and which, acting as a constellation on the organism might lower the effectiveness of the technologies employed.
