(1) After the preheated eggs are taken out of the storage room, they are naturally warmed up in the hatchery. After the temperature of the egg table reaches room temperature, the code tray is incubated. The position of the code wheel is the same as that during storage. In addition, the hatching machine is cleaned, disinfected, debugged, and warmed up.

(2) For wild geese, the incubation temperature and humidity are required to be 38.5 degrees in the first 1-28 days after hatching, and 37.5 degrees in the 28th to 31st days. If the hatcher sensor is placed on the eggs, Keep egg temperature 38-38.5 degrees until the end. Incubation humidity is different according to the different incubators. The kind of electric heating tube is directly placed in the old hatching machine which is warmed in the incubator. The inside of the machine is very windy. Incubation humidity is 60% on the 1st to 28th days after hatching, 28-31 days. It is 70%. Heating with warm air, a small incubator with a fan inside the machine, 50% of the incubators on the 1st to 28th days after hatching, and 60% on the 28th to 31st days.

(3) Turning the eggs on the 1st to 20th days after hatching, turn the eggs once every 2-3h, turn the eggs 8-12 times a day, turn the angle 90 degrees so that all parts of the embryo heat evenly to prevent embryos Sticky shell. If the temperature difference in each part of the incubator is 0.5°C, adjust it once a day, that is, aligning the upper and lower egg trays, and aligning eggs around the egg tray with the central egg to compensate for the temperature difference.

(4) The first egg was placed on the 8th day after hatching, and eggs and dead embryos were culled from the eggs. Normal embryonic development of fertilized eggs, radial distribution of blood vessels, bright red color; dead embryonic egg color is lighter, there are irregular blood ring, blood arc, no radial blood vessels; no egg shiny vascular network, can only see To the yolk shadow. The second lighting was performed on the 28th day after hatching to remove the embryonic dead eggs, and the live normal embryonic eggs were transferred to the hatch tray and hatcher. The live embryonic eggs are black and red, the air chamber is tilted, the boundary is curved, and there are thick blood vessels around; dead dark red blood vessels are not visible around the dead embryonic egg chambers, the edges are blurred, some eggs are light in color, and the small hair is bright. During the incubation process, embryos and eggs are sampled from time to time in order to grasp the embryonic development and take corresponding measures accordingly.

(5) When the hatching and hatching of the geese breeding eggs are hatched to 28 days, the live embryonic eggs should be set aside. After the plate is placed, temperature and humidity are controlled according to the temperature and humidity requirements of the geese breeding eggs. Compared with the previous stage, the temperature is appropriately reduced, and the humidity is appropriately increased to facilitate hatching. In order to ensure sufficient humidity, the number of water trays should be appropriately increased to keep the water tray clean to facilitate evaporation. The hatching begins on the 30th day and the hatching is completed. After 31 days of hatching, the geese go out of their shells, stay in the hatcher until the feathers dry, and then they are taken out and put into the brooding room or box. Picking brood too early, young chicks did not dry feathers, poor adaptability to the environment; quack chicks too late, young chicks dry feathers, you can move, the chicks may crawl out of their own, fell into the water dish drowned. During the hatching period, lights should be turned on as little as possible, and lights should be turned on only when the chicks are brooded to prevent damage to the joints when the chicks crawl. Usually 2h picking up once. The geese breed eggs have thick shells, and the broken teeth of the young geese are not very sharp. Some young chicks do not produce shells properly. Therefore, midwifery should give birth during the hatching period. The allantoic blood vessels have withered, the inner shell yellowing, embryo eggs with scissors, etc. gently open in the blunt part of the egg, remove the eggshell about 1/3, and gently pull the head out of the young goose, put Make it out of the hatcher by itself.

(6) During the incubation period, the geese eggs should observe the temperature and humidity at regular intervals every day and make records. Generally, they are checked and recorded every 2 hours. Regularly add water to the incubator's water tray and turn the egg regularly. Pay attention to the change of ventilation and the change of instrument and indicator. If any abnormality, it should be promptly corrected. After each incubation, the incubators, hatchers and utensils should be thoroughly cleaned, brushed, and sanitized.

With the improvement of living standards, snack foods have been deeply loved by the masses of the people. When you walk into the supermarket, you will see snacks such as preserved fruit, sour horns, potato chips, almonds, pistachios, fish fillets, dried meat, and spiced fried meat. Snack foods are gradually upgrading to become the daily necessities of the people. As the economy develops and the level of consumption increases, consumers' demand for the quantity and quality of snack foods continues to grow.

Trends in the food and beverage industry, such as consumption upgrades, clean labels, and high protein, are also driving Meat Snacks at an alarming rate, from novelty, unique proteins to the use of raw materials, and innovating, while attracting consumption. Groups and consumption scenarios have also diversified, and many factors are driving the growth and prevalence of meat snacks, including tastes, product claims, and product forms.
