Under natural farming conditions, ostrich eggs are often contaminated with dirt and faeces after they fall to the ground. Contaminated eggs are subjected to multiple procedures such as washing and disinfection, or they are inevitably infected by bacteria. During the hatching process, mid-advanced and mid-adult eggs often die. Even “fried eggs†have appeared, causing the entire box of eggs to be infected and scrapped, causing unnecessary economic losses to the farm. We observed several times in the hatching bird eggs and found that the contaminated bird eggs showed multiple bacterial spots in the eggs during the middle of the incubation period, and the eggs in the post-hatching period were accelerated due to bacterial infection and their egg temperature increased. , resulting in the late death. It is usually found in the hatching process that some bird eggs have a sudden weightlessness increase at a later stage. After dissection, the chicks die and die. This is a typical bacterial infection. Implementation of "artificial egg receiving" After a long period of observation and testing, the annual egg acceptance rate is above 85%, and the hatching hatching rate is 20% higher than in the past. This method is described below for reference. First, in charge of technicians to master the opening period of ostriches, first prepare fumigation plastic bags or clean towels. 2. Instruct the breeder to observe the birds in the opening period. General Birding The birds are assisted by the male bird in the circle in the first 10 days or so. The mother bird often circles around the pit and the nose is red. When food intake decreases, especially when the prenatal mother bird walks around in the circle, the breeder should clean it with a disinfectant solution, prepare a plastic bag or towel, and wait until the ostrich is difficult to find. (The ostriches usually lay eggs around 2 to 7 in the afternoon). Third, about 2 minutes before laying eggs, the mother bird will squat, mouth mucus, flapping wings, issued tremors, began to lay eggs. At this point the egg handlers should immediately swiftly pass by, and with one hand pick the amount of eggs in one hand to gently lift the bird's tail feathers to prevent the tail feathers from being contaminated by bird eggs. When picking eggs, people must kneel to prevent the male from attacking you. Fourth, the next egg is clean and moist. The breeder must send it to the egg fumigation room in time, and the incubator takes over the storage and storage. Disinfection must be carried out after the egg surface has dried. (Plastic bags are used to pick up eggs in rainy season to prevent rain pollution). Fifth, fumigation or storage of eggs should have the air chamber upside down. When the bird produces eggs, there is a first out of the air chamber. Just take a note of the time when the egg is ingested. Inform the incubator that it will do. Accepting the egg can solve a problem identified in the direction of the air chamber.
