Many sheep breeders have experienced the experience of large-scale infection of sheep by infectious diseases and mass deaths, and have lost a lot of money. Some people, because they can't do a good job of protection, or novices don't know how to prevent it, they bury hidden dangers in the process of raising sheep and starting a business. Hua Qian today will talk about the treatment plan of infectious diseases in sheep, and the symptoms of some infectious diseases, as well as prevention and treatment methods.
1. Anthracite maggot disease
Symptoms: acute onset, coma, dizziness, swinging, falling to the ground, dyspnea, shaking of the whole body, teeth grinding, bleeding from the mouth and nose, bleeding from the anus, vulva.
Scheme: This infectious disease is very bad, basically based on prevention, because from the discovery to the death of sheep, most of them are not treated at all. So how to prevent anthracite maggot disease? Sheep should be regularly injected once or twice a year with subcutaneous vaccination of Anthracite maggot spores to prevent vaccines. Dead sick sheep must be dug deep in the pit, and it is best to burn it.
Emergency treatment: In the process of raising sheep, once it is found that a sheep has similar symptoms, immediately isolate the sick sheep, and then immediately spray disinfect the walls, ground, food trough, and sink of the sheep barn with 10% fire alkali solution, once every 1 hour, 3 times in a row. All sheep in the flock are given an urgent anti-anthrax serum and all are injected with penicillin twice a day for three to four consecutive days.
2. Sheep Rumination (Sheep Plague)
Symptoms: three to five days of persistent high fever, body temperature of more than 41 degrees, dry nasal cavity, oral mucosal ulceration, concomitant prolapse, swelling and congestion of gums, late feces with blood, thinning.
Prevention: Regular injections of binary vaccines or small ruminants for epidemic prevention.
Scheme: Find sick sheep, isolate in time, and disinfect the sheepfold. Sheep are urgently injected with small ruminant vaccine to strengthen epidemic prevention.
Treatment: intramuscular injection of the neck, small ruminant serum hit one side interferon hits the other side
Intramuscularly in the neck, florfenicol + doxycycline hits one side, sulfonamide hits one side
3. Foot-and-mouth disease of sheep
Symptoms: increased body temperature, persistent high fever, muscle tremor, mouth drenching, blisters on the skin of the mouth and hooves, ulceration or erosion, decreased or stopped rumination.
Prevention: Regular injections of foot-and-mouth disease vaccine for prevention.
Treatment plan: Sick and dead sheep should be deeply buried and incinerated. Timely isolation of sick sheep, emergency disinfection of sheep barns and surrounding areas, and disinfection of sodium dichloroisocyanurate as the main preparation can be used for extermination.
Treatment of sick sheep: 0.1% potassium permanganate solution or vinegar to wash the affected area of the oral cavity, apply iodine tincturerherol, or ice boron. Carbalin calcium plate clear granules, astragalus polysaccharide powder mixed with water for sheep to drink.
4. Sheep tetanus
Symptoms: Sheep fall out of herd, head, neck, waist and back muscles are rigid, difficulty eating and swallowing, slow movement, and even inability to lie down or stand up on their own. The eyelids are prominent, the pupils are dilated, the teeth are closed, and they stand in the shape of a Trojan horse, without drinking water or regurgitating.
Prevention: Regular injection of tetanus vaccine to sheep, sheep in case of trauma, castration, tail breakage, timely disinfection with iodine tincture.
Scheme: The sick sheep should be placed in a quiet place to avoid strong light stimulation. Wash the wounds of sick sheep with 0.1% potassium permanganate solution and inject tetanus antitoxin intravenously.
Treatment: intramuscular injection of penicillin 1.2 million units once a day. For severe muscle rigidity, intramuscular injection of 20% magnesium sulfate 50 ml and chlorpromazine hydrochloride 5 ml twice a day.
5. Lamb diarrhea
Symptoms, lamb chops white loose stools, fever 41-42 degrees, mental depression, prostration
Prevention: The ewe should grasp the fat before giving birth to enhance the physique of the ewe, the lamb will eat the colostrum in time after childbirth, and ensure that the lamb milk is sufficient during the follow-up lactation period.
Treatment: Oxytetracycline powder is taken orally 3 times a day according to body weight 1 kg 50 mg, sulfamidine is taken orally for the first time, and 0.5 g is administered every six hours.
6. Sheep are plagued
Symptoms: The flock occasionally dies of unknown causes, and the sheep have no obvious pathological features before death. Before death, the sick sheep have bloating, conjunctival cyanosis, teeth grinding behavior, and finally spasms and die. If the group is infected, it will be found that the sick sheep stand alone, the nasal end is dry, the body temperature is above 41 degrees, the sick sheep's stool is foul-smelling, and there is blood and mucus in the feces. The course of the rapid epidemic is very short, basically a few hours from the onset of the disease to death.
Prevention: Sheep are regularly injected with triple and quadruple vaccines for prevention, and the epidemic is too late to be treated.
Treatment plan: If a sick sheep with sudden death is found, or the above symptoms correspond, the sick sheep are immediately isolated, and the pen and its surroundings are disinfected with 5% concentration of fire alkali solution or 20% lime milk, and disinfected once every 1 hour, three to five times in a row. At the same time, the sheep are injected with sulfonamides to prevent large-scale transmission.
7. Dysentery in lambs
Symptoms: bowed head and back, no milk, accompanied by diarrhea, feces odor, yellow-green color, yellow-white or gray or even blood in the stool, quadriplegia, shortness of breath, mouth foam. The course of the disease is short and the mortality rate is high without timely treatment.
Prevention: Do a good job of prenatal grasping of ewes during pregnancy to enhance physical fitness, do a good job of postpartum warmth of ewes, and prevent colds. The ewe should breastfeed the lamb reasonably after giving birth to avoid uneven hunger and fullness. Lambs are fed 0.2 g of oxytetracycline powder within 12 hours of birth, after which it is given once a day for three consecutive days. The pen should be kept dry, and it is best to have the conditions to establish a separate delivery room when the ewe is producing in winter. Regularly disinfect the sheep pen and sheep barn, and the environment in which the lamb is born is as warm as possible. 7 to 15 days after birth, triple and quadruple vaccines are injected for epidemic prevention.
Protocol: Timely isolation of onset lambs. The ewe should grasp the body before giving birth to enhance the physique of the ewe, and the lamb will eat the colostrum in time after childbirth, and ensure that the lamb's milk is sufficient during the follow-up lactation period. Within 12 hours of lamb birth, 0.2 g of oxytetracycline is administered once a day, three times a day. 7 to 15 days after birth, triple and quadruple vaccines are injected for epidemic prevention.
Treatment: Oxytetracycline + protease 0.2 g each with water, twice a day.
8. Sheep pox
Symptoms: sheep fever 40-42 degrees, extreme depression, skin hairless or hairless places began to acne, obviously visible to the naked eye, acne longer and more, larger and larger to nodules, blisters after a few days, and then suppuration, the disease period of up to three or four weeks. At the same time, it can induce conjunctivitis, gastroenteritis, and sepsis in sheep, resulting in the death of sheep.
Prevention: sheep pox vaccine once a year, sheep tail subcutaneous injection 0.5 ml, goat 2 ml. Do not buy sheep in the epidemic area, when newly introduced breeding sheep, be sure to isolate for more than 21 days and then join the group.
Plan; Found to be diagnosed with sick sheep, immediately isolate the sick sheep, and inject sheep pox chicken embryonic weakened seedlings for emergency epidemic prevention for sheep who have not yet fallen ill. At the same time, the sheep pen should be disinfected immediately, and the disinfectant should use bleaching powder liquid with 2% effective chlorine. Once the sheep fall ill in a large area, there is basically no therapeutic value, so prevention is greater than treatment.
Treatment: intramuscular injection of the neck, one side of the sheep pox serum, the other side of the double yellow lian + cephalosporin + metamizole, the body surface ulcer is applied to the iodine disinfection.
Focus - sheep cloth disease
This disease can be transmitted to people, and sheep breeders must be cautious about it. Once you get cloth disease, you will lose your life.
Symptoms: miscarriage of ewes during pregnancy, yellow water before abortion, premature birth in ewes during pregnancy, stillbirth, mastitis and arthritis, walking lameness. Rams also have orchitis epididymitis.
Prevention: Regular vaccination of sheep against cloth disease, especially as self-supporting farmers. Delivery of ewes, people need to directly contact the lamb, lactation, pregnant ewe, do a good job of protection, with gloves, wear special protective clothing. Cultivate yourself to develop this hygiene habit during the sheep rearing process. Once a person is infected, he will slowly lose the ability to work, and the muscles and joints will be sore for many years, and the whole body will be weak, and the consequences will be very serious.
Plan: Once the sheep is diagnosed with cloth disease, immediately isolate the sick sheep under the premise of their own protective measures. Then report it to the relevant departments. Sick sheep and dead sheep are buried deep or incinerated. Sheep pens and sheep barns are intensively disinfected, once an hour apart, three times in a row, and then again every day for three consecutive days. Sheep without disease are immediately injected with cloth disease vaccine for emergency epidemic prevention. The sheep keeper himself, the person who is often in contact with it, immediately goes to the hospital for cloth disease testing.
Treatment: wash the uterus, vagina with 0.1% potassium permanganate solution. Treatment with sulfonamides and cixiline or streptomycin. Treatment is basically for ewes that are not diseased, and sheep that have been identified as sick should be slaughtered deep burial or incinerated.
Finally, let's talk about the commonly used vaccines for sheep that sheep farmers must plan to receive regularly:
Triple four prevention vaccines: prevention of lamb dysentery, sheep sniping, sheep rapid disease, sheep intestinal sepsis.
Diptych: prevention of sheep pox, sheep small rumination.
Lung Bing (sheep-borne thoradic vaccine): Prevents infectious pleural pneumonia in goats.
Cloth disease vaccine: to prevent sheep cloth disease, according to the cycle of two to three years for epidemic prevention
Inactivated vaccine for sheep septic streptococcal disease:
Pig, cattle and sheep foot-and-mouth disease side OA divalent inactivated vaccine: prevention of foot-and-mouth disease
Tetanus vaccine for pigs, cattle and sheep: prevent tetanus
Pox Bing: Goats prevent sheep pox
Chain Bing: Prevents streptococcus diseases
For farmers, developing the habit of planning epidemic prevention and regularly vaccinates the sheep can reduce a lot of unnecessary losses in the process of breeding and entrepreneurship. Most of the vaccine areas can be provided free of charge to farmers, some of the vaccines without free policies, farmers should not have a fluke mentality, should be self-funded to vaccinate the flock, for their own cause of an insurance operation, so that their sheep breeding business can flourish.
