(1) Etiology: Infectious abortion, more common in brucellosis, bender disease, trichomoniasis. Non-infectious persons can be found in uterine malformations, placental necrosis, fetal inflammation and polyhydramnios, etc.; medical diseases such as pneumonia, nephritis, toxic plant poisoning, salt poisoning, pesticide poisoning; nutrient metabolism disorders such as lack of inorganic salts, etc. Insufficient or excess trace elements, insufficient vitamin A, vitamin E, etc., feed freezing and mildew, etc.; surgical diseases, such as trauma, sepsis, and transport congestion can also cause miscarriage.
(2) Symptoms: Sudden occurrence of abortions, with no characteristic features before delivery. People with slow onset have poor mental performance, loss of appetite, abdominal pain from lying down, vomiting screaming, amniotic fluid outflow, and remaining quiet after the fetus has been discharged. If the cause is the same in the same group, abortions will occur one after another until the victim's miscarriage is completed, before it can stabilize. Traumatic causes of the disease can make the sheep recessive abortion, that is, the fetus does not excrete itself, dissolves on its own, forming a fetal bone residue in the uterus. Due to the varying degree of trauma, fetuses injured by cattle and sheep nets are often excreted within hours or days due to fetal membrane bleeding and exfoliation.
First of all, you should choose to put pastures. In the spring, we should make good use of the spring grass resources in various places, including plains, rivers, ditches, roadsides, low-lying lands, forest farms, riversides, hilly lands, and places that could not be reached in the winter. In the summer when the forage is flourishing, the high nutritional value of the heading and flowering is a good time for catching earthworms. Dryness, ventilation, coolness, convenience of drinking water, and few mosquitoes and snakes should be selected. Before the hot season arrives, attention should be paid to the shading and ventilation of the Boer goat field. Summer grazing should take full advantage of the coolness of morning and evening to allow the sheep to feed. The weather in the autumn is cool, with little rain, and the ground is dry, and the vegetation is lush, the herbaceous seeds are stalked, the straw is harvested, and the nutritional value is high. It is an excellent opportunity to catch the autumn crops. At the same time when straw is harvested in the agricultural area, the stubble land can be used for 15 days. About this time, large groups can grazing. In winter, the climate is cold. Grazing can only eat yellow pastures and leaves. At this time, attention should be paid to the quality of pasture and straw harvested in summer and autumn. Attention should be paid to the combination of legumes and grasses. Wherever conditions permit, alfalfa and other forages can be grown, and feeding sheep in winter can play a decisive role. Silage and other forms can also be used to compensate for the lack of subtilis.
At the time of grazing, the gypsophila grazing method is usually adopted in large grazing pastures; in the long and narrow area, one-line grazing method is adopted. At this time, attention should be paid to the foreskin; in the sporadic places, the method of solitude can be adopted, especially next to crops. The grass in the land should be even more so. Try to avoid grazing after the rain or when there is too much dew. Grazing in mountain areas and pastoral areas should pay attention to the protection of pasture and the maintenance of pasture diversity.
