Farming technology (1) feeding management: quail feed can be divided into two categories: plant feed and animal feed. Plant feed includes corn, wheat, broken rice, rice bran, wheat drum, peanut cake, soybean cake and so on. Animal feed including fish meal, inorganic salt. Matching feed should pay attention to the following points:Feed should be matched according to the different growth periods of quail. According to the experience of Beijing Crane Farm, the feed formula for quail 1-35 days old is 25% soybean cake, 15% fish meal, 4.5% drum skin and 1.5% bone meal. Adult quail feed formula: corn 55.5%, 22% soybean cake, 14% fish meal, bone meal 2%, acacia rice flour 6.5%. Feed diversity appropriate mix of animal and plant feed to keep the feed relatively stable, do not change too much, because the quail is more sensitive to feed changes. Self-feeding method is suitable for wet and dry, with the feed should not be used for too long each time, so as not to deteriorate, affecting the growth and development of quail or poisoning death. For domestic or professional quail breeding, there must be a number of different forms and structures of quail house, to be economical and practical, according to local conditions, to meet the needs of quail growth and development and reproduction. Quail house can be divided into small, medium and large according to the feeding capacity of three small-scale ad can support 500-800, suitable for family rearing, the width of the front 3.6 meters, 1.8 meters long, the height of the front 2.4 meters, the height of the back 2.1 meters. The inner partition wall of the house is divided into two rooms, the large room is 2.7 meters wide and 1.8 meters long, which serves as a feeding room, and the rest of the room is used for storing tools and feed. The roof can be made of zinc sheets. Covered with asbestos tiles or shingles, with two exhaust holes and windows around the house, four six-layer rearing cages can be put into the quail house for rearing. The medium-sized house can raise 1,000 to 3,000 birds and is suitable for rural professionals. The front side is 5.4 meters wide and 3.6 meters long. The feeding room is 6.6 square meters and the rearing room is 13.2 square meters. The room has a drawing room, a fattening room, a brooder room, a quail rearing room, and an incubation room, all with windows and exhaust holes. Large quail farms usually raise more than 5,000 quails. It is similar in structure to a medium-sized house, but larger in size. (2) Reproduction In order to select quails with high quality and strong disease resistance, female quails should be selected with large abdominal cavity and strong egg-laying power, and male quails should be selected with large body size and fully extended claws, which are favorable for mating and reproduction. The ratio of male to female should be 1:2 or 3. Eggs should be brightly colored, clearly spotted and of moderate size so that the hatchability of the eggs is high. Domesticated quail have lost the habit of hatching eggs, so there are two forms of hatching. ① Natural hatching of quail eggs with hens, but only 7~8 eggs can be hatched at a time. ② The hen should be chosen to hatch 20~30 eggs, and the chicks should be carried away immediately after hatching, so that 3~4 broods can be hatched consecutively. ③ There are many kinds of artificial incubation, such as trough hatching, barrel hatching, flat box or vertical box hatching. Bucket hatching method is to paste several layers of paper around the bucket and put the fried rice into the sack. Salted eggs as a heat source are also packed in sacks with a layer of rice in the bucket. Incubation managers must strictly control the rules of incubation in order to obtain a high hatching rate. Flat box hatching method is generally applicable to small and medium-sized quail farms. It has a simple structure and is easy to manufacture and operate. This box is 157 cm high, 96 cm long and 80 cm wide. A 5 x 5 cm wooden square is used for peripheral support, and two layers of fiberboard are used for the periphery and the door, with fiberglass sandwiched in the middle to provide heat insulation. The flat box is divided into upper and lower layers. The upper layer is the incubation chamber and the lower layer is the heat source chamber. The two layers are separated by a 0.3 cm thick iron plate. The heat source room is equipped with a fireproof door and is heated by charcoal, kerosene or 500W electric stove. Thermometer, egg baskets and egg turning racks are placed in the incubation room, which should be kept at 20~24℃ and 60~65% relative temperature to improve the hatching rate. On the third day after hatching, turn the eggs twice a day and cool them for a few minutes each time. After 11 days of incubation, check the eggs. If the eggs are red or black and light cannot penetrate, they are normal eggs. After 15 days of incubation, place the eggs in a young egg tray. Usually after 17 days of incubation, the fertilized eggs develop into quail chicks, which are removed and fed in the brooder.
