In order to raise the fertility rate of quail eggs and increase breeding efficiency, the following aspects of management work must be done. First, light 性 Sexual maturation in about 6 months, that is to begin mating and laying eggs. Every day during the production of eggs to maintain 18 hours of light, artificial light to be added to the time, the light should be stable, do not flicker, flickering. Generally 3 watts per square meter, light bulbs from the ground 1.8 to 2 meters is appropriate. Second, the density For breeding commodities, 20 to 30 eggs per square meter, 10 for breeding eggs, and no more than 15 eggs. If the density is too high, the fertilization rate of eggs will be reduced and the hatching effect will be affected. Third, drinking water As the temperature rises, the demand for water is increasing. It is necessary to maintain adequate clean drinking water, change the water once a day, and wash the tank with 0.1% potassium permanganate solution to ensure the healthy growth of the seed pods. , improve mating ability and egg production rate. Fourth, feed During the breeding period, the nutrient components should have a total metabolic energy of 2750 to 2800 kcal and crude protein of more than 18%, and be careful to add trace elements and vitamins. The feed formulation is: yellow corn (crush) 50%, wheat flour 11%, 16% of bean cake, 10% of imported fishmeal, 3% of bone meal, 1.1% of shell powder, 0.4% of salt, 0.5% of additive, mixed well, fed regularly 3 to 4 times a day, each day ~35 grams. V. Ratio of male to female The male and female species must be properly matched, generally 1:4. Because the cockroaches can produce 8 to 10 consecutive fertilized eggs at a time, the fertilization rate of the egg can be guaranteed to be above 90%. Six, feeding methods In order to be free-range, most of them adopt three-dimensional cage culture and can make full use of the culture area. According to the proportion of 1 male and 4 females (1 group), the cages per square meter can raise 2 to 3 groups, so that they can assist in reluctant mating. Mothers escape from the pursuit of public money to achieve the goal of increasing fertility.
