African ostrich is the largest bird in the world, which has the advantages of fast growth, high reproduction rate, herbivore, strong disease resistance and wide adaptability. African ostriches were originally wild in Africa, and were artificially raised in South America earlier in the world, with a history of 100 years. In China, 1988 has successfully started artificial trial breeding, and 1992 has introduced artificial breeding and feeding of ostriches to many areas. But it is still in the stage of seedling propagation and popularization. At present, it has become a worldwide green project, and raising ostriches has been recognized by the world as a modern emerging animal husbandry.
Ostriches are treasures, and about 90% of them can be used as commodities. Ostrich meat belongs to red muscle. It's tender and as delicious as pork and turkey. Better than beef, pork and chicken. It is rich in protein, low in fat and cholesterol, and contains 2/kloc-0 kinds of essential amino acids. According to the determination, 100g ostrich meat contains 62mg of cholesterol (83mg of beef and 93mg of pork) and 2g of fat (beef 17g, pork 19g). 1 Adult female ostriches can produce 50 commercial meat birds and 2250 kilograms of lean meat every year, and the ostrich meat output is 9 times that of beef. 1 day-old ostriches can weigh up to 100 kg, produce more than 50 kg of meat, and the slaughter rate is 58%. Ostrich feeds on herbivores and has no drug residue, so it is an ideal healthy food for human beings. 1 Female ostriches lay 80 ~ 120 eggs a year, about 15.54 cm long and about 12.69 cm wide. The ostrich egg is the largest among birds, with an average egg weight of 1329 g, and the maximum 1500 ~ 2000 g. 1 ostrich egg is equivalent to 24 eggs (unfertilized eggs), which is edible, delicate in taste and rich in nutrition. Ostrich eggshells are thick and hard, and their teeth are bright. It can be used as various carving and painting ornaments, and its technological value is quite high.
Ostrich skin is the most precious leather in the world at present. Its texture is soft and tough, and its durability is five times that of cowhide. Because ostrich skin contains natural oil, it can resist cracking, hardening and drying. The feather roots on ostrich skin form natural circular patterns, and the leather products made are of high value. Ostrich can produce1000g feather per ostrich hair, which is used in modern automobile industry, electronic industry and decorations. Wool is also valuable. 1 ostrich can produce ostrich hair about 1.8kg, which can be used as high-end fashion food. High-quality fluff has fine and soft texture, excellent hand feeling, good thermal insulation performance and high price.
In addition, ostrich oil can be used as advanced cosmetics and skin care products. Ostrich viscera, male ostrich whip and ostrich bone all have certain medicinal value. The organic tissue structure of ostrich cornea is very compatible with human eyes and can be used as a substitute for human cornea. Ostrich tendon has been successfully transplanted into human body.
Artificial ostriches mainly feed on forage grass, which is resistant to rough feeding, with strong reproductive rate and fast growth. 1 ostrich can be listed from12 to1April, and its weight can reach about 100 kg. After peeling, about 50 kilograms of lean meat was obtained. Suitable for intensive production and wide adaptability. Adult ostriches live in the open air except when laying eggs, and their breeding techniques are simple and easy to master. Low consumption, high output and huge economic benefits, and its products are in short supply in the international market. At present, ostrich development bases have been gradually formed in various parts of China, and the output of "commercial birds" will increase rapidly. The meat supply, leather processing and comprehensive utilization of by-products of ostrich are transitioning to the stage of large-scale commodity production and developing steadily and healthily. ..
