Muscovy Ducks or Western Ducks (also known as Barbary Ducks) are thick, smooth and hard, unbreakable, tightly sealed, and relatively small in surface area. Directly affect the gas exchange, moisture evaporation, heat transfer and clamshell hatching, resulting in low artificial hatching rate. Sichuan Qingshen County Breeding Technology Institute adopted a bionic incubator to effectively increase the hatching rate and breeding rate of Muscovy duck and Western duck eggs. Practice has shown that using this method than the conventional hatching method to improve the shelling rate of 10-15%. Now the relevant technology is introduced in the following: First, the composition of the imitation main incubator thermostat: It consists of a vertical incubator and a flat hatching kit. During the pre-hatching period, the duck eggs are self-incubated, and the duck eggs are hatched in a vertical box. The characteristics of uniform heat supply of the bottom of the vertical box and the surrounding storage heat source allow the Muscovy duck eggs to be uniformly heated. After 17 days of incubation, the eggs are hatched. As the temperature rises gradually, the Muscovy duck eggs should be transferred from the vertical box to the flat hatching box. The temperature of the eggs can be adjusted within the required range by increasing the cold and hot water to the flat hatching box. Reduce, thicken, thin or open the cover of the incubator box, so as to adjust the oxygen supply, cool eggs, humidification and other issues in the middle and late stages until the hatched embryonic eggs, so that it is in a state of imitation of natural hatching, not only significantly raising the eggs of the duck. The hatching rate also enhances the adaptability of the ducklings to the natural environment. Second, the preservation and placement of eggs: In the environment below 18 °C below the preservation time of 6 days, the hatching rate is higher, to select clean, fresh duck eggs hatching, laying eggs horizontally, contribute to the normal development of embryos. Third, temperature and humidity control: 1 temperature. Eggs were preheated at 36-38°C prior to hatching and preheated for 6-8 hours. The incubation process temperatures were 1-7 days at 39-39.6°C, 8-19 days at 38.5-39.0°C, and 20-30 days at 38-38.6°C. , 31 days to the shell 38.6-39.2 °C. 2 humidity. Control humidity should be two high, the middle level. Pre-humidity is high, can make the eggs heat a good, uniform; mid-term, is conducive to the embryo's metabolism; later and hatching stage, increase the humidity can dissipate too much physiological heat, so that the eggshell structure loose, so that the clam shell hatch. However, when the humidity exceeds 75% and the ventilation is poor, embryos may cause acidosis due to poor gas exchange, resulting in the death of embryos. This is most worth noting. Fourth, cool eggs and water spray: cool eggs and water spray is an effective measure to adjust the temperature and humidity, a great impact on the hatching rate. 1 should cool eggs in time. The egg temperature can reach 38.8°C during the later period of incubation. Cool eggs strengthen the gas exchange of the embryos and eliminate heat build-up in the eggs to prevent the embryos from suffocating. The eggs are cooled 2-4 times a day and continue to hatch when the temperature drops to 35°C. 2 spray water. Water spray can damage the shell membrane; promote continuous contraction and expansion of egg shells and shell membrane, destroy their integrity, increase permeability, speed up water evaporation and normal egg weight loss, so that the expansion of the volume of the gas chamber and oxygen supply adequate; Causes the shell to be crunchy. When the temperature is high, it is necessary to spray the cold and boiled water to hatched embryo eggs (early water spray is not favorable for the collapse of the allantois) for 17 days; when the temperature is low, spray with warm water of 35-40°C. Spray once a day, spray the eggs until they are soaked, and let them dry before hatching. 5. Turning eggs: Turning the eggs can promote embryo activity and prevent the contents from sticking to the eggshells, making them evenly heated. During the incubation process, eggs should be turned manually or rolling once every 8 hours. The angle of turning the egg should be 180 degrees to ensure that the allantoic sac is closed at the head in time. In addition, the egg weight loss rate has a certain impact on the hatching rate. If the evaporation of water is insufficient, the weight loss of the egg is small and the gas chamber is small, some embryos in the latter stage will die due to lack of oxygen, resulting in a drop in hatching rate. Therefore, we must increase the frequency of eggs to monitor the weight loss rate of eggs, and timely adjust the temperature and humidity to ensure the normal development of embryos.
Red Ginseng is widely used in daily life. It can be sliced in the mouth for a while, chewed, brewed tea, swallowed after grinding, or swallowed.
Fried soup, stew. Among them, chewing is the simplest way to take it. Cut red ginseng into thin slices and take 2-3 slices and 3 grams or so in your mouth for a moment. Chew them carefully when saliva is abundant in your mouth. Or tea, cut red ginseng into thin slices, take 2 - 3 grams in a bowl or cup, add boiling water to brew, cover for 5 minutes, then take, chew and swallow the ginseng slices several times. When used at the end of grinding, the ginseng is ground into fine powder and swallowed every day. The dosage of red ginseng in this method is less, depending on the individual's physique, generally 1-1.5 grams per time.
