The broodstock for quail breeding should be carefully selected to ensure high fertility and quality offspring. Female quails should be chosen with a body length of at least 35 cm, weighing between 50 to 150 grams. They should display a clearly visible zona pellucida (a clear area around the yolk) and have an enlarged belly with a swollen genital opening. Ideally, they should already be laying eggs. For males, select those that are over 55 cm in length and weigh more than 150 grams. They should show blood-streaked markings on their ventral side, and when the abdomen is gently pressed, a transparent fluid should be released. A microscopic examination of this fluid can confirm the presence of sperm. It is recommended to pair 2 to 3 females with one male to optimize breeding success.
To enhance breeding performance, several techniques can be employed, such as using oxytocin to stimulate ovulation, increasing water exchange, adjusting breeding density, and providing high-quality feed. Another option is a single injection of LRH-A (Luteinizing Hormone-Releasing Hormone Analog). Females should receive 10 micrograms per 50 grams of body weight, while males should get 15 to 25 milligrams per tail. Males should be injected 24 hours before females. The injection depth should not exceed 0.5 cm, and the volume should not be more than 1 ml to avoid complications.
Artificial insemination involves holding the female quail by the front with a towel and pressing its abdomen backward with the other hand. If the cloaca is blocked, it may need to be carefully cut open to extract the egg. The extracted egg should then be placed into a disinfected container. The selected males are euthanized, and their testes are removed, ground, and filtered through a 100-mesh sieve to collect the semen. This is then mixed with the egg and stirred for five minutes. Any remaining tissue or blood is washed away with saline solution. At least two males should be used for each batch of eggs to ensure successful fertilization.
For incubation, the water depth should be approximately 10 cm, and the water should be changed frequently. However, the temperature must not exceed 4°C. The higher the temperature, the shorter the incubation period. Fry cultivation is best done in concrete tanks. 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. The fry stocking density should be around 200 per square meter. After one to two months, when the fry reach about 10 cm in length, they can be transferred to the rearing pond for further development.
Gas Grill
The gas oven is a modern cooking device that combines efficient heating and easy operation. It uses clean gas as an energy source to heat ingredients quickly and evenly through a precisely controlled flame, and whether it is baking pizza, barbecue or baked bread, it can be easily harnessed to bring mouthwatering taste. Gas ovens are not only easy to operate and quickly preheat, but also energy efficient, making them ideal for modern kitchens and commercial dining venues.
When the Gas Pizza Oven is working, the gas flow is controlled by the gas valve. After the ignition device ignites the gas, the flame burns in the furnace to produce high temperature. Heat is transferred to the pizza through the furnace wall, which heats it evenly and gradually RIPS it. Gas pizza ovens are usually equipped with temperature control systems that can precisely adjust the baking temperature to ensure the baking effect of the pizza.
High efficiency: Gas Pizza Oven heating speed, can reach the required baking temperature in a short time, improve baking efficiency.
Temperature control: Equipped with advanced temperature control system, the baking temperature can be accurately adjusted to meet the baking needs of different pizzas.
Environmental protection and energy saving: Gas as a clean energy, combustion produces less waste gas, less pollution to the environment. At the same time, the gas pizza oven has a high energy efficiency ratio, which can effectively reduce energy consumption.
Easy to clean: Components such as furnaces and baking nets are usually made of easy-to-clean materials, which facilitate daily maintenance and maintenance.
