A Review on Some Parameters of Environment in Youth Intensive Raising of Japanese Quail

The aim of this paper is to review the state-of-art of scientific research on some environmental parameters recommended by the literature in the intensive raising of young quails. As a result of the research it can be said that the temperature in the raising area of the young Japanese quail varies between 35 º - 37.8 º C in the first week of life, after which it decreases by 3-4 ° C / week. The relative humidity in the shelter of young quails in the first week of raising must be maintained at 80% (made with trays of water); then it should decrease at the value of 70%. Light regime recommended for intensive young quails raising can be 24 hours light per day to 42 days or can choose a program of light of 24 hours a day during the first 7 days of life, after which it can be reducde up to 16 hours a day until the age of 42 days. Light intensity should be between 20 lux and 45 lux for the first 7 days of life of the youth, then can be reduced by 20 to 5 lux until the age of 41 days. Density per area unit in the house is of 150 chicken / sqm (for ground riasing), reaching the age of 6 weeks at a density of 100 chicks / sqm or 250 chicken / sqm cage (in the case of youth raising in batteries) The number of chickens decreases to 250 for 1.5 sqm of cage area in the second week of life and 250 chicken for 2 sqm cage area in the third week.
