The broodstock selection for quail breeding is crucial for ensuring successful reproduction. Female quails should be chosen based on specific physical characteristics: a body length of at least 35 cm, weight between 50 to 150 grams, and a visibly enlarged zona pellucida area with an inflamed vent. The presence of eggs is ideal. For males, the selection criteria include a body length over 55 cm, weight above 150 grams, and visible blood-streaked markings on the underbelly. When pressed, their abdomen should release a transparent fluid, which can be examined microscopically to confirm the presence of sperm. It is recommended to pair 2–3 females with one male to optimize breeding success.
To enhance fertility, several methods can be employed, including oxytocin injections to stimulate ovulation, increasing water exchange, adjusting breeding density, and providing high-quality feed. A single injection of LRH-A (Luteinizing Hormone-Releasing Hormone) can also be effective. Females should receive 10 micrograms per 50 grams of body weight, while males are given 15–25 mg per tail. Males should be injected 24 hours before females. The injection depth should not exceed 0.5 cm, and the volume should not surpass 1 ml to avoid complications.
Artificial insemination involves gently holding the female by the front with a towel and pressing her abdomen backward to expose the cloaca. If the cloacal opening is blocked, it may need to be carefully cut open, and the egg squeezed out. The extracted egg is placed in a disinfected container. Selected males are then euthanized, and their testes are removed, ground, and filtered through a 100-mesh sieve to collect the semen. This is mixed into the egg container and stirred for 5 minutes. Any residual tissue or blood is washed away with saline solution. At least two males should be used for each batch of eggs to ensure higher fertilization rates.
For incubation, maintain a water depth of about 10 cm and keep the temperature below 4°C. Frequent water changes are necessary, but higher temperatures will reduce incubation time. A concrete tank is ideal for raising fry. A small amount of manure water can be added to promote the growth of silkworms, and aquatic plants like water hyacinth should be introduced to provide shelter. Fry stocking density should be around 200 per square meter. After 1 to 2 months, when the fry reach approximately 10 cm in length, they can be transferred to a rearing pond for further development.
