Many people feel that they are relatively blind in the process of raising sheep. They don't know what time to do. And because the management of sheep in all aspects is not timely, the benefits of raising sheep will be affected. Now that it has entered the fall, the temperature is getting colder, so what do you need to pay attention to when raising sheep in autumn? Let's take a look at it.
First, deworming
Autumn is the golden season for sheep to catch and breed, and before that, the parasites inside and outside the sheep must be cleaned up.
1. Fasciola hepatica
Grazing sheep is particularly prone to liver schistosomiasis, which is mainly parasitic in the liver bile duct of sheep, can cause acute or chronic hepatitis and cholangitis, and is associated with systemic poisoning and malnutrition. The diseased sheep often have jaws and neck. Department and abdominal edema, the incidence of sheep is usually more serious, and young sheep can cause large numbers of deaths due to this disease. Grazing sheep or flocks in high-incidence areas of liver flukes can be dewormed with targeted drugs such as chloramphenicol (Bayer 9015), triclosan (Liver), bromophenol Phosphorus (purine net), pendichlorosamine (chlorhexidine aniline) and dichlorophenol (Bed) and other drugs, the specific usage and dosage can be referred to the drug description, generally in the middle to late August to early September.
2. External ectoparasites
Common ectoparasites in sheep include cockroaches, fleas, scorpions and mites. The affected sheep will show itching, skin irritation, redness and hair loss, and hair loss. The rest, feeding and growth of the sheep are affected. It will reduce appetite and become thinner. For ectoparasites, 0.1% trichlorfon solution or 0.1% amitraz solution can be used for medicated bath, spraying or smearing. It can be carried out from early September to mid-September. It is best to choose good weather from 11am to 3pm. Do not do so, do not spray it into the eyes, nose, mouth and feeding trough to avoid poisoning.
3, internal parasites
Common parasites in sheep are more common, such as aphids, mites, nematodes, trematodes, hookworms, mites and whipworms. In most cases, sheep will infect a variety of internal parasites, mainly characterized by loss of appetite and indigestion. , malnutrition, anemia, weight loss and diarrhea and other symptoms. For internal parasites, ivermectin subcutaneous injection + levamisole or albendazole can be used for combined deworming, which can better kill most of the in vivo and ectoparasites, in September. From the middle to the end of October to the beginning of October, strictly control the dosage according to the drug instructions, and it is best to first test the small group and then deworm.
Second, epidemic prevention
The epidemic prevention of the flock is mainly concentrated in the spring and autumn, and the following epidemics are required in the autumn.
1, triple four vaccine
For the prevention of Clostridium fungal diseases, there are sheep rapid plague, sheep black plague, sheep intestinal toxemia and lamb dysentery, the immunization period is generally 6 months, so the spring is free of triple quadruple vaccine until the fall still needs to be Once, it can be arranged from mid-September to early October, but at least 10 days apart from the deworming.
2, sheep foot and mouth disease vaccine
It is used to prevent foot-and-mouth disease (commonly known as "No. 5 disease"). Its immunization period is generally 4-6 months. Therefore, it is necessary to prepare a sheep foot-and-mouth disease vaccine in spring and autumn. It can be arranged 10 to 15 days after the triple-four vaccine.
3. Goat infectious pleuropneumonia vaccine
It is used to prevent infectious pleuropneumonia in goats, which is often referred to as “sheep lung disease†and “rotten lung diseaseâ€. The immunization period is generally 1 year. The sheep foot-and-mouth disease vaccine was carried out 10 to 15 days later.
4, sheep aphthous vaccine
For the prevention of sheep's mouth sores, that is, the infectious pustosis of sheep, the immunization period is generally 6 months. Because the vaccine stability is poor, the sheep farm that has not had sheep's mouth sore can be done without doing it. The pleuropne pneumonia vaccine is administered 10 to 15 days later.
5, small ruminant vaccine
It is used to prevent small ruminant plague, and its immunization period is as long as 2.5~3 years. It is only suitable for sheep that are outside the immunization period and older than 6 months of age in spring and autumn. It can be arranged after the sheep's mouth sore vaccine. 15 days.
The above epidemic prevention procedures are for your reference only, and can be arranged according to the local epidemic.
Third, preparation of grass
In autumn, all kinds of pastures and crop straws are very rich, and sheep farmers should seize the opportunity to store large amounts of fodder for winter and spring seasons.
1, all kinds of pasture
Leguminous forages include alfalfa, sand sorghum, clover, etc., which can be stored and dried. The grasses have grasses, sweet grasses, ryegrass, etc., which can be stored after harvesting.
2, corn stalks
Corn stalks are best stored in silage. After harvesting, they are crushed and placed in a silage tank to be compacted and sealed.
3, soybean straw
Soybean straw can be stored by means of drying and stacking, and then crushed and processed.
4, peanut meal
Peanut meal is also stored by means of drying and stacking. However, it should be noted that some peanut meal contains mulch film, and the film must be cleaned before it can be crushed.
Fourth, breeding
Autumn is the golden season for ewes to breed and conceive. It is necessary to do a good job in estrus identification, breeding and miscarriage.
1, estrus identification
When the ewes are in estrus, there will be loss of appetite, loud screaming, water flow mucus, chasing each other with other sheep, climbing across other sheep and accepting other sheep climbing, etc., can also use a ram every morning and evening to hold the ewes After a lap, the ewe who meets the estrus will stop.
2, breeding
8~12 hours after the ewe's estrus is basically the best breeding time, that is, the ewe turns from excited to quiet and begins to accept other sheep climbing. When the water mucus becomes sticky, the breeding rate is the highest. Increasing the conception rate of breeding can be repeated once every 8 to 10 hours after the first breeding.
3, miscarriage
Ewes no longer estrus after 21 days of breeding, basically can confirm pregnancy, must strengthen the management of breeding, do not exercise vigorously, do not drink dirty water, do not feed moldy or contaminated feed, after about 5 months Time can produce lamb.
The above is the autumn sheep raising notice introduced by the small series of Huinong. It is mainly divided into four parts: driving, prevention, preparation and matching. Each point is not the same management method. Therefore, the sheep farmers must pay attention to it. Only by doing a good job of management can we breed fat sheep.
