At present, ostrich breeding is becoming a hot line of business. However, people's understanding of ostriches is still relatively shallow, and less is known about ostrich disease control.
Brooding period
Brooding is an easy-to-produce period for various diseases and an important period for success or failure. The diseases that caused the death of the chicks 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 bird's mental state and feed intake, and problems should be solved in a timely manner. The litter in the brooding room must be soft, hygroscopic and difficult to generate dust, and minimize the interference of stress factors. In addition, visits by foreigners, especially those working on other poultry farms, should be declined to prevent the invasion of pathogens.
Growth period
During this period, the ostrich grows fastest, and its 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. If it develops into a waste food, it will die after 2 to 3 days. The necropsy shows that the front stomach is full of sand and its weight is 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 the 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.
Cheng Yu
Adult ostriches have a strong resistance to disease. But this does not mean that adult 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 the aforementioned pathogens, but adult birds have not seen clinical symptoms. There is no direct data on the productivity of ostriches. Currently, ostriches raised on certain domestic farms have caused Newcastle disease, resulting in more serious Economic losses should be given great attention by the majority of ostrich farms (households). 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 addition, Chengyu can produce 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.
