Shiji, alias pheasant chicken, red-legged chicken, Dora chicken, etc., the American quail is the domestication of wild pheasant meat and eggs as well as broiler chicken varieties. Shiji has delicate meat, fragrant game, rich nutrition, soft and thick bones, small internal organs, and a slaughter rate of over 82%. It is a high-protein, low-fat nutritional tonic and special poultry product.
Biological characteristics
China's wild pheasants are mainly distributed in the southwest of Xinjiang, Qinghai, Gansu, and North China to the northeast. They like to inhabit rock slopes and gravel slopes in low mountain and hilly areas, as well as plains, grasslands, and deserts. The diet is miscellaneous, feeding on the buds, leaves, berries, seeds, lichens, lichens, and insects of herbs and shrubs. Hi warm and dry, avoid cold, hot, wet, sensitive, timid and frightened, screaming high, phototaxis. Hi group house, sand bath, combative, usually more ground activities, can also fly, there is a nest. During the breeding period from April to May, 9 to 20 eggs are laid in each period, and the egg weight is 19 to 20 grams. The incubation period is 22 days to 24 days. Changying nests in shrubs and grasses between the base of the hanging rock, hills and valleys.
Construction site
Select land with high dryness, flatness, sunny wind, adequate ventilation, adequate water supply, and well-drained sandy soil. In areas where the temperature difference is small, a closed chicken house may be used in a simple chicken house, or even in the open air, in areas with large temperature differences. In order to keep chickens, playgrounds and skynets, the nets should be built with stone, brick or earth walls (40 cm to 100 cm) for chickens to inhabit, and nests should be placed on the northern wall of the house (6 chickens about 1 square meter). Egg production area), sports grounds set sand basin or sand for its sand bath. According to the size of the house, the cage can be raised in 3 to 5 layers, with a cage height of 45 cm and a width of 60 cm. The bottom net is low, high and high (with hen and chicken cages), and each cage is equipped with free dung. Plates and cages are placed behind the cages. Domesticated broilers can use no spawning boxes.
Chicken rearing
Artificial brooding can be ground flat, online flat raising and three-dimensional cage (bottom net mesh 0.6 cm 0.6 cm). Padding is done on the 7-day-old inner net so that chicks can move and prevent injury. The temperature from 1 day to 5 days is 36°C to 37°C, then 1°C every 4 days, 1°C every 3 days after 10 days of age, 1°C every 2 days starting from 21 days, and starting every day at 28 days Reduce the temperature by 1°C, and remove the temperature when the temperature is the same as the ambient temperature. When the temperature is lower than 18°C ​​when the rainy weather temperature is lower, heat the air. The relative humidity from 1 day to 3 days is 65% to 70%, from 6 days to 65% at 4 days to 7 days, and then maintained at 55% to 60%. 7-day-old chicks, ground brooding, 30 incubators/m2 under warming umbrella, 40 heating methods/m2, online, cage, box brooding, 70 to 80/m2; 14 days old, above Each way of brooding density must be halved. Illumination is 24 hours at 7 days, 14 hours to 21 days at 16 hours to 18 hours, and gradually reduced to natural light. Within 1 day to 3 days after hatching, add 0.02% oxytetracycline and a suitable amount of vitamins to cool boiled water, which is similar to the body temperature of the chicks. The first few days of feeding with cooked egg yolk and yellow mealworms can also be fed with full-priced chicken and cooked eggs (one egg is added for every 50 eggs). After 7 days of age, 40% of the commercially available chicken material, 20% of cooked egg yolk, 20% of mealworm, and 10% of green feed were fed. Later, with the growth of chickens, eggs and tenebrio are gradually replaced with protein meals such as fish meal and soybean meal, and vegetables containing crude fiber are appropriately fed. The material was continuously fed within 3 days and fed 5 to 6 times on the 14th to the 28th day, and 3 to 4 times on the 28th. From 1 day to 3 days of age, artificial contact and a variety of sound, light, and color stimuli can be enhanced to acclimate their stress adaptability.
Breeding management
During the breeding period, the stone chicken is warmed to the pre-production stage at 30 days of age. Early chickens have not yet matured and can be mixed with males and females. 35 chickens from 70 days old to 70 days old can raise 20 eggs per square meter, and can be halved at 70 days of age. This period is mainly based on commercially available broiler chicken feed. Tenebrio, green feed and health sand are added. Feed 3 to 4 times a day, each fed 35 days to 70 days, 30 grams to 35 grams, 84 days after 55 grams to 60 grams. Restricted feeding of pheasant should be adopted, and low-energy, low-protein (14.5% to 15% of crude protein) feed quality should be limited to feeding, free intake, and reduced pupa production. However, amino acids need to be balanced and provide sufficient minerals and vitamins. The first week of feeding restriction should be gradually transitioned to avoid stress; broiler chicken is not limited to feed, increase energy protein feed, 90 days of age when weighing more than 0.5 kg can be slaughtered.
Adult broiler breeding management
Undomesticated broilers are generally sexually mature from 10 months of age to 11 months of age. Breeders are very sensitive to temperature, too high (above 30 °C), too low (below 5 °C) will affect the egg production and fertility rate. The humidity is maintained at 50% to 60%, the density is about 8 cells per square meter, and the light is gradually increased to 15 hours to 16 hours before the birth, and the environment is kept quiet during the production period. The protein in the diet should be sufficient, vitamins, trace elements and minerals (especially calcium) should be comprehensive. You can feed commercially available ingredients, plus appropriate amounts of cooked eggs or minced meat, live worms, and vegetables, etc., and feed them 1 time each morning and afternoon.
