1 Single-cage breeding Coops for artificial insemination must be kept in single cages. A cage or two groups or groups of people tend to affect semen quality due to stress (eg cock climbing, fighting, etc.). According to relevant research, if two or more roosters are kept in the same cage, most of them will have only one rooster capable of producing semen, and almost all the other roosters will not be able to extract semen and semen. Mostly the most dominant cage. The results of the single-cultivated rooster cage culture experiment designed by Beijing Agricultural University in 1983 confirmed that the species of male roosters raised in a single cage had a large amount of sperm extraction, high sperm density, weight, success rate of sperm collection, cleanliness of semen, and survival rate of roosters. Indicators are higher than single-cage double-raising. 2 Temperature and light The length of day when the cockerel starts to produce semen is negatively related to the length of the light time. During the increase of the light length, sperm production can be promoted, and the decrease of the light length can inhibit the production of sperm. The irritative effect of light on the testis is mainly in the pre-growth stage. It is believed that at least 12 hours of light per day is required to achieve maximum growth of the rooster testes and a large amount of sperm production. Adult roosters produce ideal semen quality at 20-25°C. Temperature above 30 °C will cause temporary inhibition of sperm production; and temperatures below 5 °C, cock sexual activity will be reduced. Sacton (1964) adult males were exposed to high temperatures of 39-49°C and relative humidity of 50%-68% for 2-5 hours. As a result, the amount of semen dropped rapidly (50%) and sperm density decreased by 1/2-1/. 3. The semen quality of the test cock takes 5-9 days to return to normal. Illumination time 12 to 14 hours cock can produce high-quality semen, less than 9 hours of light, semen quality decreased significantly. Light intensity of 10Ix can maintain the normal reproductive performance of the rooster. However, the development of weak light can be delayed (Lake, 1974). 3 Weight check To ensure the health of the roosters and high quality semen during the breeding period, the body weight should be measured weekly (monthly), and the body weight should be adjusted. All roosters with body weight above or below the standard body weight of 100g or more are kept separately. For roosters used for artificial insemination, sperm collection should be paused or the sperm collection interval should be extended (once every 5-7 days).
