[Effect of the lighting regimen during the raising of breeding and market laying hens].
Studied was the effect of illumination intensity on the physiologic state of the body, growth and development, egg laying capacity and the economic effectiveness in the raising of growing stock laying hens and adult ones in three-tier cell batteries of the BKM-3 and BHK-H types. The content of hemoglobin, total protein, calcium, inorganic phosphorus, alkaline phosphatase, and erythrocyte count. Determined was also the content of some fat-soluble vitamins in the liver as well as the glycogen level in the liver and muscles and the amount of blood sugar. Certain changes were established in the investigated hematologic and biochemical indices along with the rise of effectiveness in using an illumination programme of low light intensity with regard to the type of birds mentioned above.
