Spring pigs should pay attention in the following five aspects.
Providing a good environment for the pigs to keep the pig house warm, dry, and ventilated, improve the hygiene of the pig house, pay close attention to the disinfection of the pigsty, and eliminate the living environment of the bacteria, which is the first priority for spring pig raising. Pigs like the dry environment, especially the body temperature regulation function of piglets is not yet well-developed, the body surface deposited less fat, poor cold resistance. In early spring, the weather in March is suddenly changeable. The temperature difference between day and night is relatively large. Therefore, it is necessary to hang curtains, block loopholes, and lock the shed to ensure the pig house is warm, the environment is dry and clean, and the air is smooth. In northern regions, sows are also required to implement a warm real estate to ensure that the piglets they produce are all basic work.
At the same time, it is necessary to thoroughly disinfect the pig houses to prevent the growth and reproduction of germs. The sheds are cleaned and then sprayed and brushed with 20% to 30% lime milk or 20% ash or 2% to 3% pyrogenic alkali solution on the ground, walls, and surrounding environment of the enclosure. After washing utensils, use 3%-5% of Lysol children to disinfect, and then rinse with water, so as not to cause poisoning or affect the pig's feed intake.
Strengthen the epidemic prevention and timely repellent pests Spring must strictly prevent the occurrence of infectious diseases such as swine fever, erysipelas, pulmonary epidemics, piglet paratyphoid, panting, transmissible gastroenteritis, and piglet E. coli. Farmers should strictly immunize pigs in accordance with immunization procedures, and should not avoid missing injections or vaccine failures. If there is an outbreak in the surrounding area, in addition to a good disinfection of the piggery, foreign people and vehicles must be strictly prohibited from entering the farm, and their vehicles and personnel should be thoroughly disinfected from the epidemic area.
Communication in winter and spring, warm and cold, is also a high incidence of parasitic diseases, avermectin (insect buster) is the preferred drug for farm parasite control, safe and reliable. Application: 1. Every spring and autumn, one application of the drug is applied to the whole pig. Concentrate 1.5-2.0 g of avermectin (0.2%) powder per kilogram for free intake for three days. 2. For pregnant sows, one application of the drug is given within one to two weeks before delivery, and the rate is 2.0 g/kg. The nursing sows are fed at a rate of 1.0 g/kg and eaten freely for three days. 3. For boars, they are usually dewormed once in spring and autumn; Each time, the mixture was mixed at a rate of 2.0 g/kg and was fed freely for three days. 4. The piglets are driven once every 20-30 days (during feeding of piglets) and 60-70 days (during transfer of piglets). The first time is to mix 0.5 g/kg and 1.0 g for the second time. / Kilograms of ingredients, free intake, use for three days.
Focus on nutrient supply to adjust feed formulation According to the different growth stages of pigs, scientifically feed the full-price diets with different nutritional standards, and timely adjust the diet formula according to the weight of the pigs, feed intake, etc. Spring green feed is lacking. It is necessary to add as much as possible juicy diets such as carrots and brewers' grains and cakes in the diet in order to promote the appetite of pigs and supplement some vitamins.
Feeding and management of piglets for fine management science feeding of finishing pigs and breeding pigs can be conducted as usual. However, the feeding and management of piglets must be meticulously managed because piglets lack the innate immunity, and their body temperature regulation and digestive functions are not perfect. In the spring of climate change, there is a slight mistake in feeding and management, and it is easy to cause piglets to become ill and even die in large numbers. Therefore, it is necessary to improve the feeding of sows and maintain the cleanliness of the breasts; it is necessary to open the food, make feeds, and savor the food; the safe has a good birth, feeding, and weaning, and we should especially nurse the weaned piglets. The prevention of diarrhea in piglets should be followed by injections of vaccines at the end of the period of the pregnant sow, pay attention to the environmental hygiene and postpartum improvement of the pig's constitution. Adding compound additives, providing clean drinking water, giving adequate light and proper exercise, and promoting the healthy growth of pigs, so that pigs can safely survive the spring season of this disease-prone.
Pay attention to the prevention of common pig diseases in spring In addition to the severe infectious diseases such as swine fever and erysipelas, due to the effective control of scientific immunity, there are many pig diseases that can easily occur in the spring. The most common diseases are diarrhea, mycoplasma pneumonia, influenza and piglet edema trees. .
Diarrhea is a common disease in spring, including infectious gastroenteritis, rotavirus disease, E.coli disease, red piglets, paratyphoid piglets, swine dysentery, etc. The main symptoms are diarrhea, which is caused by multiple causes. Caused by the need to correctly identify the right medicine, and add body fluids to prevent dehydration and secondary infection, improve efficacy. At the same time, the entire population should be treated preventively.
Porcine mycoplasma pneumonia is a contact respiratory infection of pigs. Sudden onset may occur when the head drooping, lack of energy, open mouth breathing, and issued a sound of asthma, cough less and deep, purple mucosa, body temperature changes are not large, the mortality rate is high. When the prevention and treatment can be intramuscular injection of pig gasping, daily 2 ~ 40,000 units / kg, for 5 consecutive days for a course of treatment. One-time intramuscular injection of oxytetracycline 1 to 1.5 grams can also be given, 7 days for a course of treatment.
Swine influenza occurred in early spring and was endemic. The incidence of the disease is high. In the early stage of the disease, the pigs suddenly have fever, lack of energy, loss of appetite or no food, often lying together, reluctant to exercise, difficulty breathing, severe coughing, mucus out of the eyes and nose. If it is improperly managed during the onset, it is prone to bronchitis, pneumonia, pleurisy, etc., increasing the mortality of the pig, so it should pay attention to the prevention and treatment of this disease. Prevention of the disease should be paved and diligently change the hay, and regularly disinfect the pig house with 5% caustic soda. Pay close attention to changes in the weather. Once it cools down, heat and keep warm. To prevent contact between susceptible pigs and infected animals, pigs were inoculated twice consecutively with inactivated swine influenza vaccine and the immunization period was up to 8 months. There is no special medical treatment for the disease. Only symptomatic treatment is used to relieve the disease and antibiotics or sulfa drugs are used to avoid secondary infection. The penicillin and streptomycin may be combined with the severely ill pigs, together with the viral agent and intramuscularly, twice daily for 5 days. Antibiotics and antibiotics are added to the feed at a ratio of 0.2%, which enables the disease to be controlled effectively.
Piglet edema Disease A type of enterotoxemia in piglets after weaning caused by pathogenic E. coli occurs mainly in weaned piglets, especially in fast-growing and lyrical piglets that are 5 to 15 days after weaning. In particular, sudden changes in the feed after weaning cause changes in the intestinal microbiota. In addition, changes in the living environment and climate, as well as the lack of vitamins and mineral elements in feeds, are all pathogenic factors. The sudden onset of the disease, the initial outbreak, often see no clinical symptoms of the disease animals suddenly died. The onset was slightly slower, with an early manifestation of depression, lack of food, edema of the eyelids, head, neck, and anus, sometimes systemic edema, and finger pressure marks. At the beginning of the illness there are neurological symptoms, manifested as excitement, circling, rapid heartbeat, tremor, ataxia, and hoarseness. Later limb paralysis occurred. Acute cases die for 4 to 5 hours, and most of them die within 1 to 2 days.
If selenium induces edema disease, selenium supplementation can be used for prevention. That is, 0.1% sodium selenite is injected intramuscularly at 1 ml per kilogram body weight once a day for 3 days. Dexamethasone sodium phosphate, sulfadiazine, and vitamin C injections can be used, and the application of the fungus can be used for prevention. Treatment should also be combined with diuretic laxative detoxification, intramuscular injection with furosemide; irrigation salt laxatives such as magnesium sulfate, sodium sulfate, artificial salt and sodium bicarbonate, 1 or 2 times a day, for five days.
