SUMMARY
In order to determine the effect of using infrared lamps in raising the Jumbo youth meat quail as a source of heating and lighting during the 1-42 days of age, an experiment was organized on a total number of 300 quail chickens, divided into three equal groups (100 chicks/ group), respectively two sources of electric heating and electric lighting (control batch – 100 W power incandescent lamps, experimental batch I – 100 W infrared lamps and experimental lot II - infrared lamps in the 0-3 weeks of growth and incandescent lamps in the period of 4-6 weeks of growth).Average live weight at the age of 42 days was of 216.55 g/head in control group, of 185.56 g in experimental group I and of 248.55 g/head in experimental group II, 12,87 % higher compared to the control batch and with 25,34% compared to experimental group I, the differences between the three groups being very significant.The average consumption of compound feeds was of 1344 g c.f./head in control group, of 855 g c.f./head in experimental group I and of 1310 g c.f./head in experimental group II, the differences between the three groups being very significant.In view of the inferior results recorded in the case of experimental group I, it can be stated that the use of infrared lamps for the entire growing period of 42 days to Jumbo meat quail youth has negative effects on the weight gain of the chicks, especially in the second part of the growth. The superior growth performance of the experimental group II, compared to control and experimental group I, shows that the combined use of infrared lamps in the 0 - 3 week growth period and incandescent lamps during the 4 - 6 week period has positive effect on growth parameters, especially on the live weight of the chicks at the age of 42 days.
