The ostrich hatched technology

1 kind egg collection and storage, selection and disinfection
(1) most female ostrich breeder eggs collected in the afternoon at 3-6 egg, individual from morning or at night. An ostrich egg after picking up to timely, in order to reduce damage and eggs. Male and female ostrich protection ostrich egg instinct, pick up to 2, 1 person who will drive away, one bird eggs pick up. When the eggs should be picked clean or gloves, avoid pollution protein. The place of pollution by disinfection wet towel to wipe. Place shall register, indicate the male and female bird egg number and date and weighing Numbers.
(2) protein select qualified protein requirement, the surface should be clean, excrement and other contaminants soil, Secondly, moderate size requirement egg weight had greater than small will affect the quality of the chicks hatching rates and general requirement, selectin heavy 1.5 kg.range, more than 2 kg and less than 1 kilogram of place should be generally eliminated. The appearance of a protein requirement ovoid, 16-17 cm in diameter, width, 13-14 cm long, round, flat shape and eggs hatch deformity of Melbourne. For ivory color of place or yellowish commonly. White eggs hatch rates low.
(3) place should be preserved protein storage big vertical or tilt place, time to 3-5 days advisable, if the storage period shall not exceed seven days, don't turn eggs. If the protein storage does not exceed 4 days, save with 16-18 degrees Celsius temperature for appropriate, More than four days for 13 degrees Celsius. Relative humidity is 60%.
(4) protein disinfection ostrich egg from the matrix output would be XieShiQiang fecal pollution and adherent bacteria, along with the passage of time, the bacteria multiply, and through the stomata into egg shells on the hatch of protein. Therefore, it is necessary to place strict disinfection. Place more, general disinfection method with formaldehyde fumigated may use. Methods are put in store egg will place, or disinfect cabinet room per cubic meters of space with formaldehyde solution (formalin) 30 milliliter, potassium permanganate 15 grams of doses, at a temperature of 20-25conditions airtight fumigation for 20 minutes. Using this method, the formaldehyde should pay attention to, and potassium permanganate reaction of great corrosive. So, to use large ceramic containers, volume, add a little warm water first, then add potassium permanganate formaldehyde. Twenty minutes later want seasonable disinfection ark of smoke exhaust temperature, selectin gradually to 18 degrees Celsius, lay eggs into the chest or for hatching incubator.
2 they hatch
(1) the preparation before hatch chickens before the breeder eggs hatch room carefully check the sealing, heat preservation, ventilated condition, hatch indoor temperature is best constant in 22-25c. To hatch room, machinery, etc thoroughly disinfected. Reboot, try to 2-3 days after preheating one hatch.
(2) incubation period of management
Incubation temperature and humidity control ostrich hatched, incubation period for 42 days of constant temperature in the early period of 30 degrees Celsius, hatch 36.8-42 days, the embryo of heat, their relative low temperature, with 36 degrees advisable. Incubation requirements, low humidity inside the incubator for 20-40% of relative humidity of different countries in different areas (report inconsistent). The relative humidity is suitable to hatch selectin weightlessness rate to determine. The incubation period in place while 14% weightlessness rate, the most appropriate within the incubator of relative humidity. Incubation indoor environment relative humidity in 40% when, in basic without humidifying incubator. If the incubator relative humidity under 40, it needs to add wet. When the relative humidity 70%, incubator itself as the humidity in the incubator can drop, need to adopt the hatch of air conditioning or indoor add into the air for pumping incubator wet processing.
According to the purpose of eggs, eggs as embryonic development degree and is to observe abnormalities, timely pure egg and die without eliminating embryo eggs. According to the egg is in the first when the hatch, check place into the egg dish on whether the room at the chi. According to the egg is second in the days of the hatch, ostrich and began to form a sharp beak beak and wings, legs, roughly differentiated allantoic membrane shells to expand the inside surface of membrane, embryonic body, as when the eggs cadre is clear, the blood vessels to see the head and body cadre 2 roundlet group, called "double pearl". Article 14 the hatch for the third time in eggs, eggs, according to the black blood, see the small head, eggs, called "is full of embryos FengMen".
An ostrich egg yolk egg: double contain fattiness, lighter in weight, floating in the middle of the eggs by the chalaza fasten the embryo, absorb nutrients, eliminate wastes. If long time in a position in the e
