Piglet disease

Piglet disease are many, many of which are expired can make pigs of serious illness, and some swine disease than those terribly hard knives, which are also pig pig disease and some people focus on swine is soft knife. For example, piglet white muscle disease is a nutritional metabolic disease that causes skeletal muscle and myocardial lesions in piglets. So what is piglet white muscle disease? How to prevent piglet white muscle disease.

Clinical symptoms

　　This disease often occurs in healthy piglets, and some have a short course of disease and sudden onset. In the early stage of the disease, the performance is weak, the pig body is rapidly declining, and the symptoms are difficult to stand up. If the disease develops again, the limbs are paralyzed. Uneven breathing, frequency, rapid heartbeat, no abnormal changes in body temperature. The course of the disease was 3-8 days, and finally collapsed. In some cases, no symptoms appear, that is, rapid death. Sick pigs mainly show decreased appetite, depression and difficulty breathing. Longer course of the disease, showing hind limbs tough, arched back, difficult to stand, often standing in front of the legs or dog sitting posture. Severe cases can not sit, the hindquarters paralysis shows neurological symptoms, such as circular motion, head to one side, etc., difficulty breathing, heart weakness, and finally death. Sick piglets, lack of energy, cold, happy lying. Walking and swaying, hard limbs, difficulty standing, heartbeat and breathing fast and weak, some front legs squatting, some dogs sitting, lying down, breathing difficulties, heart weakness, and finally death.

Pathological changes

　　Muscle degeneration of the waist, back, buttocks, light color, like boiled meat, and named white muscle disease. During the necropsy of dead pigs, it can be seen that there are contiguous or focal necrosis on the skeletal muscle, the muscles are slack, and the color is gray-red, such as cooked chicken. Such gray-red cooked meat changes are often symmetrical, often found in the limbs, back, buttocks and other muscles, such lesions are also seen in the diaphragm.

　　There are pale gray or pale white spots on the endocardium, the myocardium is obviously necrotic, the heart capacity is increased, the myocardium is soft, and sometimes the right ventricle muscle is atrophied, and the appearance is mulberry-like. There are spotted hemorrhages in the epicardium and endocardium. Liver congestion is swollen and swollen, and the fragile and fragile edges are obtuse, and are light brown, light grayish yellow or clay. Commonly, there is steatosis, the liver lobule is smooth in the cross section, the periphery is pale, and the center is brown. Spotted necrotic foci with large needles and parenchymal diffuse hemorrhage are often found.

　　In the early stage of the disease, the performance is weak, the pig body is rapidly declining, and the symptoms are difficult to stand up. If the disease develops again, the limbs are paralyzed. Uneven breathing, frequency, rapid heartbeat, no abnormal changes in body temperature. The course of the disease is about 3-8 days, and finally it falls. In some cases, no symptoms appear, that is, rapid death.

Popular features

　　The incidence of piglets from 20 days to 3 months old is more common, more than 3-4 months of onset, often occurring locally.

Clinical features

　　Common symptoms include motor dysfunction (his sleep, difficulty in standing, lameness, limb paralysis); heart failure (fast heartbeat, uneven breathing, frequency); digestive disorders, diarrhea; anemia, yellow staining, slow growth and other systemic symptoms, Severe exudative quality (due to capillary cell degeneration, necrosis, increased permeability, causing edema in the chest, abdomen and subcutaneous ).

Anatomical lesion

　　The skeletal muscles of the dead pigs, such as the waist, back and buttocks, are loose and denatured. The color is light, like boiled meat, grayish yellow, yellow-white dots, strips, and flakes. The transverse diameter of the heart increases and looks spherical.

Prevention

　　1. For 3 day old piglets, 0.1% sodium selenite injection 1ml, intramuscular injection, has a preventive effect. Sodium selenite and vitamin E should be added to the sow diet.

　　2, 0.1% sodium selenite injection can be used for sick pigs, each piglet is injected intramuscularly 3ml, repeated once after 20d, and vitamin E injection, 50-100mg per piglet, intramuscular injection, has a certain effect.

　　3, pay attention to the feed mix of pregnant sows to ensure the content of additivessuch as selenium and vitamin E in the feed . Selenite preparations should also be used in combination. For lactating sows, a certain amount of sodium selenite (10 mg each time) can be added to the feed to prevent the onset of suckling piglets. Piglets in the selenium-deficient area can be born after birth. 2d intramuscular injection of 0.1% sodium selenite injection 1ml, a certain preventive effect, 0.1% sodium selenite injection for the affected piglets, intramuscular injection of 3ml per piglet, repeated 20d, and the application of vitamin E injection, 50-100 mg per piglet, intramuscularly injected. Where conditions permit, you can feed some green fodder containing more vitamin E, such as seed germ, green fodder and high quality legume hay. For lactating sows, a certain amount of sodium nitrite (10 mg each) can be added to the feed. In the selenium-deficient area, 1 ml of the sodium selenite injection can be intramuscularly injected on the 2nd day after birth. Piglet white muscle disease, previously reported in foreign countries, mostly in March and April. Sick pigs are more common from 20 days to 6 months old, and there are few adult pigs. The cause is not clear, it is said to be related to vitamin E deficiency, it is said to be related to the lack of trace element selenium, but the total is considered to be nutritional insufficiency, the feed is single and cause disease.

Prevention

　　1 After the disease occurs, it should improve the feeding and management conditions and have certain effects. However, it is often impossible to eliminate the disease, and it should also be combined with a selenite preparation.

　　2 According to the experience of treating lamb and yak white muscle disease, the treatment of sick pigs with sodium selenite has been successful. Sodium selenite is mixed in the feed, 10 mg of the sow, and 2 mg of the piglet, and repeated administration for 15 days for prevention. Another person found that in 3 to 6 months old piglets with white muscle disease in a pig farm , the remaining 283 piglets were fed with sodium selenite at 3 to 8 mg per head depending on the age of the pig, and were administered once every 15 days. A further one-third of the above dose was administered after 25 days, and the mixed feed was administered. Since then, no sick pigs have been found in either of the two sessions.

　　3 A pig farm has been injected subcutaneously with o.1% sodium selenite solution at a dose of 2-3 ml per head. As a result, the sick pig was cured.

　　4 with vitamin E500-800 mg, muscle or subcutaneous injection, for 2-3 days, after the dose is halved, and then use 4-6 days, good results can be obtained.
