The ostrich was originally a wild bird and was first domesticated in South Africa and Australia. Although the artificial breeding of ostriches has only been for more than 10 years, it has been rapidly developed around the world. In China, in 1992, Guangdong took the lead in importing African ostriches from Zimbabwe and succeeded in breeding and breeding. At present, the breeding of ostriches has been included in the Three High-level Agriculture Projects and is making an uproar in the land of China. However, people in China know more about ostriches, and they have less knowledge of ostrich disease control. In view of this, the author introduces some diseases and prevention of ostriches.
First, the performance of healthy ostriches
Healthy ostriches like to live in groups, often run and jump, like to bathe in the wet sand, normal urine without odor, no flies.
II. Disease Prevention and Control at Different Growth Stages
1, brooding period: brooding period is the prone period of various diseases, is an important period of success or failure. The diseases that led to the death of young birds during this period were mainly respiratory infections. Due to adverse environmental factors, especially sensitive to moisture and dust, chicks are often exposed to air pollution, wet ground mats, and excessive or low room temperature to induce respiratory tract infections such as aspergillosis and a series of respiratory symptoms. Sneezing, coughing, etc., if found in time, and take appropriate measures to eliminate incentives and use antibiotics, the prognosis is generally good, otherwise it can lead to death. Therefore, during the brooding period, special management must be performed and the staff should be on duty 24 hours a day. At any time, attention should be paid to the spirits and feeding conditions of the chicks and problems should be solved in a timely manner. The litter in the brooding room must be soft, hygroscopic, and hard to generate dust. Interference with stress factors. In addition, visits by foreign personnel, especially other poultry farm staff, should be refused to prevent the invasion of pathogens.
2. Reproductive period: During this period, the growth of ostriches is fastest, and the daily gain can exceed 0.5 kg. The diseases that often develop during this period include pro-stomach apposition and soft foot disease.
Pregastric desert sand disease This is a disease that causes digestive disorders by accumulating a large amount of sand particles in the anterior stomach. It can cause heart failure due to malnutrition and die. The etiology is not yet clear and may be related to the lack of trace elements such as selenium in feed. The main symptom is a reduction in food and loss of weight. Such as the development of waste food, then 2 to 3 days after death, necropsy can be seen in the stomach before the accumulation of sand, its weight up to 4 to 5 kg. Mucosal congestion in the intestine. Myocardial atrophy, edema, and loss of heart fat.
The disease can take the following measures to prevent and control: 1 In the early stage of disease, sand-grazing can be practiced, that is, a hard plastic plate is laid on the sports ground to avoid direct contact between the ostrich and the sand. At the same time improve the quality of feed, add selenium and other trace elements and vitamins in the feed, and give a wealth of high-quality green materials. 2 In the frequent and multi-disease ostrich farms, add some laxatives, such as paraffin oil, to the concentrates every few days to promote expulsion of excess sand from the body and prevent the occurrence of this disease. 3 severe illness can be treated surgically. This has been a successful experience in surgery in Shantou.
The soft foot disease is caused by excessive growth, and the weight gain of the body exceeds the growth of the bones of the feet and the calcification rate of the bone, causing the feet to become overloaded. At this time, on the one hand, it is necessary to limit the amount of feed to control the growth rate. On the other hand, calcium, phosphorus and other minerals and vitamins such as vitamin D are added to the concentrate to promote bone growth and bone calcification. In addition, check whether the sports ground is large enough and the daylight conditions of the farm.
3. Adult birds: Adult birds have strong resistance to disease. However, this does not mean that farmed ostriches can ignore the epidemic. In recent years, Guangdong, Foshan, Jiangmen, and Shantou have all detected antibodies to Newcastle disease, bacillus leukaemia, and avian botulism in birds and eggs imported from South Africa. It shows that ostriches have been infected with these pathogens, but adult birds have not seen clinical symptoms. There is no direct data on the productivity of ostriches. (Editor's note: ostriches raised on certain domestic farms have caused Newcastle disease, causing more Serious economic loss). It is difficult to predict whether the above-mentioned pathogens will pose a direct threat to ostriches as the ostrich grows in captivity and breeds. In spite of this, I believe that ostrich breeders are still incapable of taking care of them. It is necessary to do a good job of preventing disease, such as declining unnecessary visits, and setting up a disinfection pool at the gate of the farm.
According to the breeder, Chengyu may have dystocia. It is mainly due to frightened or environmental noise, such as the noise emitted by the machine when the new ostrich farm or near the site is under construction. The prevention of the disease is to eliminate incentives and provide a quiet and fresh air environment for ostriches.

The benefits of air-dried onions
1. Lower blood lipid and lower cholesterol
The sulfur-containing compounds in onions, such as allicin, have a good lipid-lowering effect and can reduce the amount of bad cholesterol in the blood, so eating high-fat steak with onions seems to make sense.
2. Relieve high blood pressure
Onion is one of the few vegetables containing prostaglandin a, which can reduce peripheral vascular resistance and blood viscosity, and relieve hypertension symptoms. For the elderly and postmenopausal women, onion is rich in calcium, which can prevent bone loss, and regular intake can also prevent the occurrence of osteoporosis.
3. Reduce the occurrence of asthma
Many people mistakenly believe that onions have a strong and strong smell and should be classified as irritating food, and people with respiratory diseases or allergies are best not to eat them. In fact, onions can inhibit the activity of histamine, and histamine is a chemical that can cause asthma allergy symptoms. Eating more onions can reduce the chance of asthma.
