The selection of good relatives and reasonable stocking are important for improving the hatching rate of quail eggs. Infants of more than 5 years of age, with sexual maturity of 1 to 1.5 kilograms, are usually used as pro-gaze, and pro-giveness requires strong, non-injury, shiny, smooth backs and quick movements. At the same time, you should also check if there is any internal injury. The method of inspection is to turn the abdomen upside down. If it is a healthy mantis, it can turn over quickly and escape quickly. The internal injuries and hooks in the body cannot be reversed. You can use two fingers to hold the upper part of both sides of the hindquarters of the hindquarters. If the hind limbs are unable to indent, then there will be internal injuries.
In general, stocking densities of 1 to 2 square meters are placed on the water surface. The total weight is about 250 kilograms per mu, and male and female ratios are better than 4:1 or 3:1. After the dearly stocking, it is necessary to strengthen the management, and to feed more animal feed with high protein to promote the development of gonads.
Meticulously collect eggs. The collection of quail eggs directly relates to the hatching rate of quail eggs. Practice shows that the key is to grasp two points: First, it is necessary to accurately determine the position of ovum nests. In the season of spawning from May to August, carefully examine the spawning grounds every morning before the sun comes out. Look for the footprints and you will notice a noticeable wet blot. This is where the spawning holes are created. mark. Do not rush to remove the quail eggs at this time, because the embryos are not fixed at this time. Moving them too early will affect the embryonic development, and then affect the hatching rate. After 8 to 30 hours, the embryos are completely fixed and the eggs are white. The extremely polar and yellow plants have already appeared clearly and can be collected. The second is to collect fertilized eggs into the egg collection box. The egg-picking boxes are wooden boxes with a length and width of 45 cm each and a depth of 8 cm. There are filter holes around the box and at the bottom. The box is covered with 2 cm of fine sand. If there is no picking box, it can be replaced by a tub or plastic basin. . When picking the eggs, use bamboo to in turn dig the eggs out of the hole. First check whether the eggs are fertilized. If the egg shell has white spots on the top, and the edges are clear and round, the egg color is bright and pink or white, it is fertilization development. A good egg, on the contrary, there is no visible white spot on the surface of the egg shell, and the color is basically - induced, then it is an unfertilized egg, or the white spot of the egg shell is a large irregular white spot, and it is an egg with poor development of fertilization. Can not be hatched.
When quail eggs are packed, the animals are to be faced up and arranged neatly in the picking box. Do not squeeze in piles. After picking the eggs, the original egg holes are filled and compressed. When drought strikes, some water should be sprayed for other relatives to continue spawning.
Control the hatching conditions. There are many kinds of artificial hatching methods for quail eggs. No matter which method is adopted, the temperature, humidity, ventilation condition of quail eggs must be controlled. Incubation temperature is controlled at 28-35 degrees, preferably around 30 degrees, not too high or too low, otherwise it will affect the hatching rate. When the temperature is low, it can be heated manually. Incubation humidity control is appropriate between 80 and 85%. If the humidity is too high, the quail eggs can easily become airtight and die. If the humidity is too low, the quail eggs can easily evaporate and the eggs will die. In addition to the use of moisture meter to control the humidity, the reliable and practical method of measuring humidity is: the sand will be squeezed into groups by hand, spread the group that spreads after the hand, indicating the appropriate humidity. Incubation and ventilation status means that the thickness of hatching sand should be moderate to ensure the oxygen required for the development of the embryo. Incubation temperature, humidity and ventilation conditions are the three key factors for the hatching of quail eggs. The three are closely linked and restrict each other, and they are adjusted to the best state of hatching eggs to maximize the hatching rate.
