Generally, long-acting oxytetracycline or long-acting ceftiofur sodium and other drugs are used, and they are injected on 3/7/21 days of age respectively.
Piglet Insulation: Since piglets are born with thin subcutaneous fat and weak cold resistance, it is necessary to strengthen the insulation. The suitable temperature for 1-3 days old is 30-32℃; the suitable temperature for 4-7 days old is 28-30℃; the suitable temperature for 8-30 days old is 22-26℃.
The main measures for piglet insulation are: first, the simple method, which is to put hay in the pig pen, close the doors and windows, and block the gaps in the wall holes to prevent cold wind from invading; the second is to build a piglet insulation room , that is, build a small greenhouse covering an area of ??1 square meter and 80-90 cm high in a corner of the sow pen, leaving a small door for piglets to enter and exit freely. The roof and surroundings of the room are covered tightly with grass, and the room is padded with dry soft grass. Infrared lights can also be installed in the chamber. The piglets are put into the insulated room after they are 3 days old after being fed. Then the piglets will find a warm window and enter the insulated room to keep warm from the cold.
In addition, the optimal humidity for pigs is 50%-80%. When the relative humidity reaches more than 80% during the piglet stage, it is easy to cause diarrhea. However, if it is dry for a long time, it can cause respiratory tract infection in piglets, so the humidity should be maintained.
Eat enough colostrum. Colostrum is the milk secreted by sows in the first 3 days after delivery. It contains a large amount of immunoglobulins, which can improve the disease immunity of newborn piglets. Therefore, within 24 hours after birth, the piglets During the period, the piglets should be able to eat sufficient colostrum.
Preventing anemia In order to prevent iron deficiency anemia in piglets, it is required to inject 100-200 mg of iron into piglets 2-3 days after birth.
Piglets fed with feed and water grow quickly, and their weight is twice that of birth at 7 days. After three weeks of lactation, the milk production and nutrition of the sow will gradually decrease, and the growth of piglets will However, more and more nutrients are needed, so artificial feeding is used to supplement the insufficient amount of pig milk. Feeding is usually started in 5-7 days. Pay attention to the fact that the feed is rich in nutrients and easy to digest; pay attention to the quality of protein and provide sufficient Drink water.
Wean piglets in about 30-35 days in a timely manner. Piglets should be fed regularly and quantitatively, and should be fed sparingly and frequently to prevent overeating. Feeding high-copper feed and acidified feed can promote piglets, but it is appropriate to feed high-copper feed no more than 2 months old, otherwise it will lead to copper poisoning and gastric ulcers due to long feeding time. Seven days after the piglets are weaned, enrofloxacin or ricomycin should be added to the feed to prevent diarrhea and piglet edema.
Extended information:
1. Avoid salt: Salt can reduce the efficacy of streptomycin. The sodium ions in salt can retain water in livestock and poultry, causing edema. Therefore, Salt feeding should be limited or discontinued when treating nephritis and using streptomycin. In addition, table salt can also accelerate the excretion of bromine preparations. When using bromine preparations to treat exciting diseases in livestock and poultry, the amount of salt fed should also be reduced.
2. Avoid bran: bran contains a large amount of phosphorus and a small amount of calcium. It should be forbidden to feed bran when treating rickets, urinary tract stones, intestinal stones, and rickets in livestock and poultry. Otherwise, the condition will worsen.
3. Avoid additives: Feed additives often contain bone meal and other minerals, which can reduce the efficacy of oxytetracycline and tetracycline. Therefore, it is forbidden to use the above antibiotics when giving them to livestock and poultry.
4. Avoid cottonseed cake: Cottonseed cake can affect the body’s absorption of vitamin A. When preventing and treating vitamin A deficiency in livestock and poultry, cottonseed cake should be stopped.
5. Avoid taking blood meal: Blood meal is a feed with high protein content. When giving Chinese herbal medicines such as psoralen, pinellia, polygonum multiflorum, raw rehmannia, and rehmannia glutinosa to livestock and poultry, they should not be taken together with blood meal. Otherwise, side effects may occur.
6. Avoid beans: Soybeans, black beans, adzuki beans and other beans contain minerals such as magnesium, iron, and calcium. They can combine with tetracycline and oxytetracycline to form substances that are difficult to absorb, thereby reducing Medicinal efficacy. Mung beans can detoxify and detoxify hundreds of medicines. Therefore, no matter what kind of medicine livestock and poultry take, they must absolutely not take mung bean products.
7. Avoid sorghum: Sorghum contains highly astringent substances that can offset the efficacy of laxatives. Therefore, it is forbidden to feed sorghum when taking laxatives to livestock and poultry.
8. Avoid spinach: Spinach contains high levels of oxalic acid. This substance can combine with calcium in the digestive tract to form insoluble calcium oxalate, which hinders the body’s absorption of calcium oxalate. Therefore, livestock and poultry should not take calcium supplements. Feeding of spinach should be stopped during preparation.
