Technical key points for raising growing pigs well in summer and autumn
Piglets are weaned at 3-6 weeks of age and kept in the nursery house for 4 weeks. When body weight is 20-50 kg, because bone and muscle growth is relatively fast, they are called growing pigs. At this stage, the protein level is 16% and the lysine content is 0.8%. At 50-110 kg, adipose tissue is deposited in large amounts, so the protein and lysine levels can be appropriately reduced to 14% and 0.65% respectively. Ordinary pig farmers are accustomed to using concentrate or premix combined with corn, bran and other raw materials for feeding, but attention should be paid to the fact that the premix produced by some manufacturers is not up to standard, resulting in pigs

Correct Methods and Operating Steps for Injecting Pigs
Injecting pigs is the main method for preventing and treating pig diseases. The commonly used injection methods include intramuscular injection, subcutaneous injection, intravenous injection, and intraperitoneal injection. Intramuscular injection: muscle tissue is rich in blood vessels, so the injected medicinal liquid is absorbed relatively quickly; in addition, there are fewer sensory nerves distributed in muscle, so the pain caused is relatively mild, making it the most commonly used injection method. The injection site is generally chosen at the well-fleshed buttocks or neck. During injection, first clip the hair and disinfect, then hold the syringe with the right hand and insert the needle vertically. The depth can be determined according to the size of the pig, and generally

Why do pigs love biting other pigs' butts?
It may be pica. This disease is one of the problems commonly encountered in pig farming, and it occurs frequently, especially in winter and spring when light duration is insufficient and temperatures are low. Improper feeding management, an unsuitable environment, unbalanced feed nutrient supply, disease and metabolic disorders are triggers of this disease. Because of long-term pica, pigs often suffer stunted growth, weight loss and loss of appetite, causing unnecessary economic losses for pig farmers. 1. Clinical symptoms Pigs with pica show tail biting, ear biting, rib biting, navel sucking, especially

Diagnosis and Treatment of Acute Selenium Poisoning in Pigs
1 Incidence and Clinical Symptoms In November 2002, a specialized pig-farming household in Wuhua County, Guangdong, raised a total of 20 piglets from the same litter. The sow's milk was sufficient, the piglets nursed normally, and they grew well; at 10 days of age, each weighed about 1.5-2 kg. The owner injected each pig intramuscularly with 2 ml of sodium selenite vitamin E injection. On the morning of the next day, 2 pigs were depressed, unwilling to walk, refused to nurse, urinated frequently while standing, with a small volume and in a painful manner, had rapid and labored breathing, walked as if drunk, wandered aimlessly, and bumped their heads against walls or circled.

How should repeated fever in pigs be prevented and treated?
Pigs suffering from "high fever syndrome" generally show persistent high fever (around 41.5°C), reddened skin with bleeding spots, cyanosis of the ear tips, congestion of the conjunctiva, labored breathing or coughing, reduced appetite, and abortion in some sows; necropsy reveals brown lesions of varying size in the lungs, and in severe cases the lesions involve the entire lung, while the kidneys appear earth-yellow (similar to the color of the kidneys in swine fever), and the lymph nodes are swollen, hemorrhagic, and juicy on the cut surface. The key to preventing and treating this disease is to adopt a prevention-first policy: first, carry out isolation, disinfection,

Prevent poisoning when feeding potatoes to pigs: these points need attention
Improper storage of potatoes can cause sprouting and rotting, and pigs are highly prone to poisoning after eating them. 1 Clinical symptoms: mental excitement and restlessness, random squealing, and running and bumping around the pen. After a long time, the pig becomes depressed, sways while walking, has weak hindquarters, and in severe cases has paralysis of the limbs, lies on the ground unable to stand, has difficulty breathing, and has cyanotic conjunctiva. If rescue is not timely, it will die of heart failure. In mild or chronic poisoning cases, the main changes are drooling, vomiting, abdominal pain, constipation or diarrhea, and bloody stools. 2 Treatment methods: suspected hors

Understanding High-Fever Diseases in Pigs in Summer and Autumn in One Article
For the pig industry, summer and autumn can span from May to early November each year. Over this half-year period, pig diseases are commonly seen and frequently occur for many reasons. According to rough statistics, the incidence of pig diseases in summer and autumn accounts for about 70% of the whole year. The notable feature of pig diseases during this period is that clinically they are mainly characterized by high fever, with body temperature mostly rising above 41°C, presenting as continued fever or recurrent high fever. Among the commonly occurring high-fever diseases are: swine fever, swine erysipelas, swine pasteurellosis, piglet paratyphoid, swine septicemic streptococcosis

How to feed finishing pigs so they grow faster
--Environmental conditions cannot be ignored. The role and influence of environmental factors on pigs are increasingly valued by people. Only by creating good living and production conditions for pigs can the effect of obtaining more and better-quality products with the minimum amount of feed input be achieved. Environmental factors include temperature, humidity, density, ventilation, harmful gases in the barn, lighting and noise, etc. 1. Temperature: Pigs have a poor ability to regulate their own body temperature; only very few sweat glands can regulate it in hot weather, and only very few bristles resist the cold of winter

How to prevent diarrhea in pigs in winter? These measures need to be mastered
1. Strengthen feeding management. The feed quality should be good, and mold and spoilage should be prevented, so that sows do not transmit it to piglets through colostrum and cause them to have diarrhea. Pay attention to keeping the pig herd warm during the cold season from late autumn to early spring. 2. Strengthen immunization. Pregnant sows should be injected with the vaccine for this disease 45 days and 15 days before farrowing respectively, and then ensure that piglets receive enough colostrum so that they obtain relatively high antibodies. 3. Pay attention to hygiene and disinfection. Strictly prohibit the entry of outside vehicles, purify the air, avoid infection by viruses and bacteria, and reduce pigs

How to Prevent and Control Common Diseases in Pigs in Winter and Spring
This disease is an infectious disease of piglets caused by Salmonella. Piglets aged 1-4 months have high morbidity and mortality rates. The disease occurs in endemic or sporadic form, often in cold, changeable weather and rainy seasons. Poor environmental hygiene and reduced resistance of piglets can induce this disease. Symptoms and lesions: In the initial acute onset, it is similar to swine fever and requires comprehensive judgment combined with other examinations. The typical symptom is persistent diarrhea with a chronic course, and some piglets also show pneumonia symptoms. Lesions: Acute cases often die of shock, with purple congestion at the extremities and systemic septic
