Goat abortion is one of the major diseases that threaten the development of the sheep industry and causes serious economic losses. With the development of the goat industry, the abortion phenomenon of goats of the right age has been increasing year by year, showing an endemic epidemic with a wide area of ​​epidemic and maintaining a high incidence rate. Seriously affect the improvement and promotion of new goat breeds and limit the development of the local sheep industry. There are many factors causing goat abortion, mainly infectious and non-infectious causes. The author will analyze the reasons for the occurrence of abortion in goats and propose treatment and prevention measures to reduce the occurrence of goat abortion diseases and reduce farmers' abortions. Economic losses.

Cause Analysis

After investigation and analysis by the author, the causes of goat abortion can be roughly divided into two categories: infectious and non-infectious.

Infectious causes

1. Brucellosis. The main clinical symptoms of sheep brucellosis are abortions, which usually occur in ewes from March to April after pregnancy. The highest miscarriage rate occurs when the disease is first infected, but most sheep get immunity and self-healing after infection. The disease can easily cause regional epidemic and spread, and poses a greater threat to humans.

2. Chlamydia disease. Chlamydia psittaci is an infectious disease that causes goats, sheep, and cattle and often results in miscarriage of goats, stillbirths, or lambs that die shortly after birth. When pregnant ewes are infected with chlamydia, they grow and multiply on the placenta, especially on the hairy leaves, causing inflammation, which results in premature birth of the fetus. February-April each year is a high incidence of chlamydial infection, the eruption of the 2nd-year-old ewe is the highest, and often shows no threat of abortion, causing a lot of economic losses to the sheep industry. The disease is often local or spread epidemic.

3. Parasitic disease. Due to the influence of traditional ideology on sheep farmers, the awareness of prevention and control of parasites in sheep is not high. Even if there are sheep farmers who control parasites, the effects and efforts are insufficient. Therefore, sheep parasites often cause herds to die. With miscarriage, parasitic diseases are the main cause of goat abortion.

Non-infectious causes

1. Influence of climate factors. The adverse climate impact is an important factor leading to abortion in goats. The environment of raising sheep is often deep in the mountains, with deep temperature difference between day and night, and large windy and cold weather. If the ewes are subjected to extreme weather stress during pregnancy, they are prone to miscarriage.

2. Malnutrition effects. Malnutrition and imbalance are important factors that cause goat abortion. At present, most goats mainly rely on grazing, and their lyrical conditions are affected by the season. Goats are fat in the summer and autumn due to fertile grasses, and they are thin and weak in winter and spring. At the same time, because the farmers do not pay attention to the feeding of the sheep in a timely manner or do not pay attention to them, goats are prone to malnutrition in winter and spring. Pregnant ewes, such as when the fastest fetal development most need nutrition, often due to inadequate feeding and nutrient supply, abortion occurs.

3. improper feeding and management. Improper feeding and management of goats is also a major cause of abortion. In the daily goat feeding process, neglecting management, not feeding in time, not providing enough drinking water, lacking sheep house with warm and cold insulation, high feeding density, long-term nutrient deficiency, and unbalanced feeding of moldy, poisonous feed, etc. Ewes were polycultured and ewes were subjected to collisions; when the disease occurred, the correct treatment method and dose were not taken, resulting in drug stimulation and miscarriage.

Prevention and control measures

1. Strengthen disease prevention and treatment. When chlamydia disease or brucellosis results in abortion of the ewes, the aborted sheep should be immediately quarantined, the fetus, the placenta and the contaminated objects thoroughly disinfected, and the vaccination should be used for vaccination to effectively prevent disease infections. Such infectious diseases should establish strict prevention and control plans to reduce the harm caused by the disease. The abortion ewes should adhere to the positive elimination system to achieve the purpose of purifying the disease.

2. Do a good job of deworming. Strengthen the deworming work of the flock and adopt new insect-repellent veterinary drugs such as worm-busting, afuding, Iraqijia, and Alijia. In spring and autumn, the insects are periodically dewormed to control and reduce the damage of the parasites in the body of the sheep. After the insects are excreted, they are fermented biologically.

3. Strengthen feeding management. Raise the level of feeding and management to avoid abortion induced by improper management factors such as crowding, lack of water, feeding of poisonous weeds, frosty grass, icy water, and cold. At the same time, scientific grazing should be implemented to timely feed the lambs, ewes, lambs, and rams to formulate winter and spring feeding standards. The ewes should adopt higher feeding standards than the pre-pregnancy standard to improve the body's immune function and supplement feeding. Sheep only do regular rations and do not supplement moldy forage or feed.

4. Supply balanced nutrition. Ensure the intake of nutrients and provide adequate, nutritionally complete forage material. In winter and spring, grazing and feeding alone cannot meet the goat's own nutrient supply, especially the growth and development requirements of pregnant ewes and fetuses. It should provide sufficient nutritionally balanced full-rate feed to ensure the growth, development of proteins, vitamins, and minerals of the fetus. Trace elements and other supplies. At the same time, it is necessary to feed more grain feed such as carrots and corn, bean cakes, cottonseed cakes or cottonseeds to increase the resistance of ewes and ensure the normal growth and development of the fetus.

5. Do a good job in sanitation disinfection. The house should be clean, sunny and well ventilated. After the winter, the excrement will no longer be removed, and the sheep will walk only to form a warm boil. Digging will be done in the spring and autumn. During the winter and spring seasons, the grass straws and ring hairs are discarded in the circle and in the trough. Remove fecal matter and weeds in a timely manner and regularly sterilize the sheds to prevent the introduction of the disease.

6. Handle immunity. Prepare immunization procedures according to local conditions, inject anti-abortion vaccines in advance, prevent the introduction of foreign diseases, and use artificial insemination techniques as far as possible to prevent infection.
