[Effect of different lighting regimens in the commercial raising of breeders].

Studied was the effect of illumination of varying length and intensity under the industrial raising of broilers. It was found that the use of an illumination programme with an interrupted light regime and low intensity of light affected the live weight, feed intake per unit of produce, and morbidity and mortality rate. The economic effect produced with the introduction of an illumination programme with an interrupted light of low intensity after the first week of BTR-3 regulation consisted in the increase in the production results in the conditions of industrial broiler arising.
