1. The feeding and management principles of the rearing and management species and the commercial production of egg tarts are basically the same. The feeding and management of egg and meat types have their own characteristics. 1, transfer group: bred maternal to 35 days to 40 days of age, about 2% have been put into production when the group should be transferred to familiarize with the new environment. It is advisable to transfer food at night and supply drinking water and seed feed in a timely manner to keep it quiet. At the same time when the group is transferred, a strict selection is made according to the requirements of the species. 2. Egg laying rules and useful life: The egg laying time of the laying hens is mainly concentrated in the afternoon until 8:00 pm, while the 3 pm and 4 pm are the most. In the case of cage rearing, the breeding females have a useful life of 1 year to 2 years, but they generally use “cleaning year after yearâ€. Breeding farms can use 2 to 3 years, but in practice the seed collection time only uses 8 to 10 Month to ensure the quality of eggs. The product egg tarts only use 10 to 12 months. Production should mainly consider the egg production, the rate of qualified eggs, fertilization rate and its economic benefits and breeding value. 3. Forced moulting: If using the 2nd laying cycle, artificial moulting is required. The natural moulting time is long, the moult is slow, and the egg production is not concentrated. Implementation method: stop the material for 4 to 7 days, darkness, forcing the production stalls to quickly stop production, then remove the feathers, and then gradually feed to make it recover quickly. It takes only 20 days from the end of the feed to the restoration of production. Drinking water can not be interrupted. We must eliminate sick and weak individuals. 4. Routine management points: 1 It is necessary to maintain the normal supply of feed and drinking water, and adjust the diet according to the egg production rate and temperature. 2 to prevent uterine ectropion, pay attention to control weight and twist. 3 Eggs are collected once at night and in the morning. They should be packed in egg trays to prevent stacking damage. 4 prevent all kinds of stress and prevent animal damage. 5 Make daily records and statistical reports work. Second, the breeding management of the pupa development period refers to the feeding and management of 15-day-old to 35-day-old (egg quail) or 40-day-old (meat quail). All kinds of young pigs use limited feeding. The meat is stocked with Tsai (with the depleted seedlings) until the growing season (sometimes by fattening). Male masturbation matures 10 to 14 days earlier than females, but the body weight is lower than that of females. There are mating and mating behaviors up to about 40 days of age. The sign also shows that cloacal glands have developed and secrete foam. The species of Tsai used to be selected from 5 to 6 weeks of age, and the numbers were registered and transferred to breeding facilities. Meat stew basically adopts the management principle of egg stew, but its raising standards are higher, and some units use the diet of young turkeys. The effect is acceptable. European and American countries adopt the "flat-cage" combination method, that is, early raising, cage breeding after 20 days of age, and some are transferred into fattening cages after 25 days of age. Its cage height is 12cm, 80pcs/m2, dark light, and the top of the cage is made of gauze or plastic mesh. Diets can be properly blended with energy and fat feeds. In management, attention should be paid to keep warm and keep quiet, and prevent all kinds of stress from causing frightened groups. Male and female cockroaches should be kept in separate cages. Regular feeding, darkening after feeding, can be used intermittent light system, that is, 1 hour lighting, 3 hours dark, can get a higher live weight, survival rate, reduce the feed ratio. The timely listing can get a lower feed ratio. At the same time, we should select high-yielding varieties, improve the formula and management of the diet, increase the survival rate, increase the live weight, and reduce the material consumption, so as to obtain good economic benefits. Third, the brooding feeding management 1, open water and open food: hatching chicks should be eaten within 24 hours of warm water, add water consumed by the body. When introduced at a distance, add 5% to 8% glucose to drinking water, and add 0.01% potassium permanganate to drinking water on the third day. After drinking, you can start eating and add 0.1% oxytetracycline powder to the powder to prevent the occurrence of white feathers. Generally, it feeds 6 times to 8 times a day, and can also be allowed to feed freely. Average daily feed intake: 3 to 4 grams on 3 days, 5 to 7 grams on 5 days, 9 grams to 11 grams on 7 days, 13 grams to 15 grams on 11 days, 16 grams to 15 days Grams. 2, daily management: 10 days to 4 days of age often show wild fleeing, feeding, feeding should be careful. 2 feed and drinking water guarantee supply. Prevent feed from splashing and prevent drinking water from wetting hair. 3 Diligently check and adjust the indoor temperature, humidity, ventilation, and light. 4 Diligently observe the dynamics and defecation of the chicks, check and adjust the density, and prevent the occurrence of warts. 5 Do a good job of preventing rat damage, animal pests and preventing gas poisoning. 6 Regularly weigh and check feather growth. 7 do a variety of records and statistical reports. Fourth, the breeding technique has lost its nesting nature and requires artificial hatching to reproduce offspring. At present, due to the lack of specialized breeding farms, appearance and weight combined methods are used. 1. Selection of seed pods The seed pods should have pedigrees or sources and should meet the appearance and growth standards of the varieties or strains. The feathers meet the characteristics of the species or strain and are full and shiny and have a strong body. Requires public sex characteristics, cloacal glands are well developed, heads are large, cheeks are bright reddish-brown (brown chestnut type), there are black and bright cockroaches, well-developed chest, strong legs, claws spread well, claws pointed Taxes are crisp and loud. The mother is required to have a large body, a small head and a handsome face. Her eyes are divine, lively and active, her neck is slender, her posture is well-balanced, and her feathers are bright. With the arrival of the peak of egg production, the plumage is turned from chestnut to brown. 2. The ratio of male and female mating for natural mating is usually 1:2 to 1:3, and for large mating is 10:20 to 10:30. 3. The relationship between breeding age and fertilization rate and hatching rate The breeding season has the best time for breeding. It directly affects the fertilization rate and hatching rate of the breeding eggs. For this reason, attention must be paid to the age structure.
