In the past two years, the American market for medicinal specialties, foods, and ornamentals has always been promising, and the aquaculture industry has become increasingly popular. However, alfalfa breeding is not as simple and easy to cultivate as it was described. Only by mastery of skilled farming techniques can the success of breeding be ensured. Now the key to the management of cockroach brooding is introduced as follows: 1. Temperature and humidity 1 Temperature and temperature are the most critical link during cockroach brooding, and the appropriate temperature can improve the survival rate. The room temperature of 1 to 2 weeks of age should be controlled at 33°C, indoor temperature of 3 to 5 weeks old at 28°C, 26 to 7 weeks of age, and 24°C after 8 weeks of age. 2 Humidity and humidity are too large for fungal infections; humidity is too small to get respiratory diseases. Generally, the relative humidity of 1 week old is 60%-70%, and the relative humidity after 1 week old is 55%-60%.
2. Ventilation Under the premise of ensuring the temperature, appropriate ventilation should be performed to increase the oxygen emission of carbon dioxide, and the metabolism of the proficient chicks should be carried out normally. 3, Density density is too large. The activity site is restricted and fight each other, and the death increases. The density is too small to waste the effective site and raise the cost of breeding. Normally, it can be put into an average of 80/m2 around the age of 10 days, about 50/m2 at 10 to 28 days, 30/m2 at 4 to 10 weeks, and 15 at 10 weeks. About m2.
