Which diseases cause high fever in pigs without purple patches on the skin?
1. Japanese encephalitis: The body temperature of affected pigs is 40-41°C, with teeth grinding, circling, visual impairment, and blind charging. Sows abort, and boars develop orchitis, which gradually atrophies and hardens, causing loss of breeding ability. For treatment and drug prevention, antiviral preparations such as amantadine and ribavirin combined with interferon, along with traditional Chinese medicine preparations for clearing heat and detoxifying, and antipyretic-analgesic preparations, should be used together, which has a certain therapeutic effect. 2. Pseudorabies: It mostly occurs in piglets aged 1-4 weeks, and piglets over 60 days of age show mild symptoms. Body temperature is 41-42°C. In the early stage of the disease, the pigs are restless and excitable

What are the treatment methods for gastric food stagnation in pigs?
Cause: Gastric food stagnation in pigs is caused by feeding too much after starvation, with the pig overeating to satiety, resulting in the accumulation of food in the stomach and the onset of disease. Symptoms: The sick pig has reduced or no appetite, sometimes vomits, and the vomited material is rather foul-smelling; the abdominal circumference is distended and enlarged, and on palpation the abdominal wall is firm and painful; breathing is rapid, and body temperature is generally normal. Treatment: Formula 1: Mix 100 milliliters of vinegar and 15 grams of salt into the feed and administer orally. Formula 2: Mash 250-500 grams of green vegetables into juice, mix with 60-90 milliliters of sesame oil, and administer orally (

What effect does airflow have on the growth of pigs?
The effect of airflow on the pig's body mainly influences heat loss from the pig. Under general environmental conditions, as long as airflow exists, it can promote convective heat loss and evaporative heat loss from the body. When the ambient temperature is below the lower limit of the pig's suitable temperature, the effect of airflow increases the amount of heat lost from the pig's body, making the pig feel cold; at this time, in order to maintain body temperature, more energy must be consumed. Conversely, when the ambient temperature is above the upper limit of the pig's suitable temperature, because airflow helps the pig's body dissipate heat, and when the airflow is strong more heat is lost, increasing the wind speed

There's an art to feeding pigs with homemade feed: keep these three precautions in mind
Whether for family or intensive pig farming, using homemade pig feed can greatly reduce feeding costs. However, when feeding homemade pig feed, you must grasp three "precautions." Pay attention to the types and proportions of raw materials. The commonly used raw material proportions for pig feed are: grains such as corn, rice, barley, and sorghum, which should generally account for 50%-70%; bran types such as wheat bran and rice bran, which should generally account for 10%-20%; toxic cottonseed cake, meal, and rapeseed cake, etc., should be less than 10%. Animal protein feeds such as fish meal

What actually causes pigs to like rooting at their pens?
1. The pigs are not fed enough; 2. The pigs may be sick; 3. The pigs lack some kind of trace element. You can bring in some soil for them to root in, or let them outside to root in the soil freely, or you can put down some coal cinders for them to root in. It is best to feed them concentrated feed.

What are the simple methods for identifying sick pigs?
1. Look at the eyes. A healthy pig has bright, spirited eyes; if a pig's eyes are dim, red, or have excessive eye discharge, it is a sign of illness. 2. Look at the skin. A healthy pig has smooth, rounded skin and full muscles; if the pig's skin is rough and hard, lacks elasticity, or has swelling, ulcers, red spots, or festering patches, it is a sign of illness. 3. Look at the coat color. A healthy pig has a glossy, lustrous coat; if the pig's hair is rough, hard, lacks elasticity, and is messy, it is a sign of illness. 4. Look at the snout disc. A healthy pig has a moist snout disc with beads of sweat; if the pig's snout disc

A Detailed Explanation of Comprehensive Prevention and Control Methods for Tail Biting in Pigs
Tail biting in pigs is a type of pica, a stress syndrome caused by disorders of nutritional and metabolic function, abnormal taste perception, and improper feeding management. The incidence rate is particularly high from August to December and from January to March, generally occurring in pigs weighing 18-80 kg, with a higher incidence rate in pigs weighing 24-40 kg (12-14 weeks of age). More sows are affected than boars; it is estimated that approximately 4.6% of boars and approximately 3.4% of sows are bitten. I. Causes of the Disease (I) Improper Feeding Management: High stocking density and too many pigs per pen

What are the treatment methods for keratitis in pigs?
Causes: Keratitis is a general term for inflammation of the corneal tissue. It is often caused by trauma, being struck by the tip of a leather whip, or puncture wounds to the cornea from sharp foreign objects. Symptoms: Keratitis in pigs presents as photophobia and tearing, pain, conjunctival redness and swelling, closed or partially closed eyelids, congestion of the blood vessels around the cornea, and diffuse opacity that gradually spreads from the periphery of the cornea toward the center, appearing light gray, milky white, or orange-yellow. The corneal epithelium swells and the surface becomes rough and uneven. When superficial damage occurs to the cornea, the surface epithelium detaches and shows marks, and transparency

Can Keeping Chickens, Ducks, and Geese Together with Pigs Lead to Highly Pathogenic Avian Influenza?
Poultry should not be kept together with pigs, because influenza viruses from poultry can infect pigs, and human influenza viruses can also infect pigs. Since influenza viruses have 8 different nucleic acid segments, when these two different virus particles infect a single cell together, their nucleic acid segments undergo reassortment and rearrangement to produce new types of influenza virus particles. These new influenza virus particles can often cause major epidemics in humans, resulting in great harm. In addition, chickens should not be kept together with waterfowl such as ducks and geese, because

Methods for Transporting Live Pigs Over Long Distances in Hot Weather
1. Keep the purchased live pigs in holding and feed them for about 7 days, so that the pigs recover their normal physical condition before shipping. 2. Fattening pigs transported over long distances in hot weather must be quarantined one by one, and sick, disabled or inferior pigs must absolutely not be loaded onto the truck. 3. Before shipping, the truck carrying the fattening pigs must be carefully overhauled to prevent the truck from breaking down on the way and delaying the rush transport time; in particular, trucks that previously carried pesticides or other toxic substances must be strictly cleaned and disinfected to avoid toxic bacteria infecting the pigs. 4. Do not use truck bodies that absorb a large amount of heat to transport fattening pigs, to prevent the fattening pigs from suffering heatstroke
