Pheasant hatching eight points

Select eggs. Try to use the preserved eggs within two weeks. The eggs are normal, moderate in size, uniform in thickness, uniform in color, and bright in color. The shorter the preservation time, the higher the hatching rate.

Disinfection is disinfection. Before flocking, it is generally sterilized by fumigation, that is, 15 g of potassium permanganate per cubic meter of space, 30 ml of formalin, and fumigation at 25°C to 30°C for 20 minutes to kill the eggs. Virus. Disinfection is generally performed in a sterilizer.

Temperature is the temperature. Temperature is the primary condition for hatching. Incubation temperature should be based on the development of the embryo to take a higher temperature in the early stage, the middle level, slightly lower in the later period, and a slightly higher temperature during the incubation period. Temperatures of each period: Eggs are preheated for 6 to 8 hours before hatching. Egg temperature is 36°C to 38°C, 1 to 7 days are 38.8°C to 39.2°C, 8 to 14 days are 38.5°C to 38.8°C, 15 to 20 days are 38°C~ 38.5°C, 21 to 24 days (ie shelling) 38.5°C to 39°C.

Wet or humidity. Humidity also plays an important role in the entire incubation process. If the humidity is insufficient, it will cause the embryo to stick shells, difficulty in hatching, high humidity, easy to cause poor absorption of yellow eggs, poor quality, and easy to die. Suitable humidity should grasp the principle of two high and middle level, ie, the relative humidity in the early period is 60% to 65%, the middle period is 55% to 60%, the later period is 60% to 68%, and the hatching period is 70% to 75%.

Turn over eggs. In order to make the eggs heated evenly, the eggs must be turned manually or naturally. From the second day after hatching, the eggs are turned once every 2 to 4 hours, the angle of turning eggs is 180 degrees, and the turning starts on the 21st day. egg.

Let the air dry. Eggs should be air-dried at 38.8°C during the latter part of the incubation period, and should be dried once a day for 16 days; hatched for 21 to 24 days and dried twice a day. The time to air the eggs can be controlled flexibly according to the situation. When the temperature drops to 35°C, the incubation continues.

Spray water. Spraying water is one of the key measures to increase the hatching rate. Water spray can make the shells crispy. The pheasant has a thick film on the eggshell and the eggshell is hard. For this, spray water once a day for 21 to 24 days. The water temperature is about 35°C. After the water is dry, it will continue to hatch. Under the action of repeatedly confining the eggs and spraying water, the eggshells will be hard and crisp, which will help the chicks break through the shells.

Take it as it is. The first time the eggs are incubated for 6 to 8 days, the eggs are mainly examined for the fertilization rate. As the normal eggs, the eye spots on the embryos can be found. The eggs are red and bloody, but no eggs are present, and the egg yolks are intact. The egg white is transparent, and it is necessary to remove the lean egg in time. The number of quail eggs should be determined according to the specific circumstances, mainly check the embryonic development, and detect dead fetus eggs.

Application

Nutritional Supplements

Hyaluronic acid extracted from rooster combs cannot be absorbed by the intestinal tract. But, Japanese scientists have developed a proprietary enzyme-cleaving technique to lower the molecular weight of hyaluronic acid without altering its chemical nature. This allows hyaluronic acid to be taken orally as a nutritional supplement, many varieties of which are readily available for commercial use.
