Detailed Explanation of Effective Methods for Chemical Castration of Pigs
For young male pigs raised for fattening, once they reach a certain weight, their testicles must be surgically removed. Below is an introduction to a chemical castration method. This method is very simple: inject a mixture of sodium chloride and formaldehyde solution into male piglets within 10 days of age, and their testicles will begin to swell, then subside on their own after 5 days. After about half a month, the testicles shrink significantly and lose sexual function. The specific method is: dissolve 10 grams of sodium chloride in 100 milliliters of distilled water, then add 1 milliliter of formaldehyde solution, shake well and filter. This makes the chemical castration solution, which can be stored in a sterilized bottle for later use. Injection

What are the treatment methods for zinc phosphide poisoning in pigs?
1. Cause: Zinc phosphide is a rodenticide, and pigs sometimes become poisoned after accidentally eating bait containing zinc phosphide. 2. Symptoms: vomiting, diarrhea, vomit and feces carrying a garlic odor; severely affected pigs die immediately, while generally within 2-3 days skin bleeding and hematuria may occur, finally leading to coma and death from convulsions, that is, seizures. 3. Necropsy: the mucosa of the digestive tract is red and swollen, bleeding, and sloughing; the liver is enlarged and friable; the kidneys are enlarged; hemorrhages occur in the heart and muscles; the blood is dark black. 4. Prevention: bait containing zinc phosphide should be properly placed to prevent pigs from accidentally eating it.

A Detailed Guide to the Prevention and Treatment of Fractures and Dislocations in Pigs
A crack in a bone caused by the impact of external force is called a bone fissure (also known as incomplete fracture), and a break is called a fracture (also known as complete fracture). When the articular head of a bone leaves the joint socket and cannot return to place on its own, it is called a dislocation. When the two opposing articular surfaces cannot contact each other at all, it is called a complete dislocation; when the two articular surfaces are partially in contact, it is called an incomplete dislocation. 1. Causes Traumatic fractures are caused by various mechanical violent impacts, such as whipping, fierce fighting, falling, jumping, etc. Fractures occur easily in cases of rickets, osteomalacia, and osteomyelitis.

What to Do About Calcium Deficiency in Pigs? Cause Analysis and Calcium Supplementation Prevention and Treatment Methods
Symptoms: In the early stage, symptoms include reduced appetite, pica, and a tendency to lie down. In the middle stage, affected pigs move stiffly, adopt an arched-back posture, and sway in the hindquarters; some develop lameness, with the hock joints of both hind legs sunken inward and splayed apart in a "V" shape. In the late stage, affected pigs lie down and do not walk, with both hind legs extended forward beside the abdomen and both forelegs bent beneath the chest. Most affected pigs have an oval-shaped cystic swelling below and behind the hock joint. Treatment: For severe cases, first disinfect the cystic swollen areas on both hock joints, then pierce them through with a three-edged needle and drain the contents. Then administer calcium gluconate by intravenous injection, 3 g per 50

The previous batch of pigs had blue ear disease (porcine reproductive and respiratory syndrome). How should the pen be disinfected?
1. Cleaning and washing. Remove all contaminants and bedding from the pen, and sweep down the dust from the ceiling as well. Then pile it all together to ferment. Then rinse thoroughly with clean water. 2. Disinfection of the floor and walls. For the floor, use caustic soda or sodium hydroxide. For the walls, spray with iodine-based or chlorine-based preparations. 3. For metal equipment that is not afraid of heat but is afraid of corrosion: use a blowtorch (alcohol blowtorch, kerosene blowtorch). 4. For enclosed pens: fumigation. Peracetic acid, formaldehyde, or potassium permanganate can all be used. After sealing for 2 hours, ventilate for 7-10 days. Basically it takes half a month.

What are the prevention and treatment methods for winter diarrhea in pigs?
Winter diarrhea is winter epidemic diarrhea in pigs. The peak incidence period is from mid-December each year to mid-January of the following year; the onset is acute, the spread is rapid, and the epidemic area is wide; the incidence rate is high and the mortality rate is low, seriously affecting the growth and development of pigs. Symptoms The incubation period of the disease is generally 12 hours to 18 hours. After infection, adult pigs show symptoms of watery diarrhea. The feces are initially grayish-white, gradually becoming yellowish-green, with an offensive fishy odor. Abdominal distension, vomiting, and body temperature initially rises to 40°C to 41°C. Once the diarrhea passes, the body temperature drops, and the pigs are thirsty and eager to drink. 10

How to surgically treat intestinal necrosis caused by umbilical hernia in pigs
If a pig's umbilical hernia is treated in time, it is generally very easy to cure and intestinal necrosis will not occur; if treatment is delayed, the intestinal tract that has fallen into the hernial sac will undergo necrosis. In most cases where necrosis occurs, the hernial ring is relatively small, and the fallen intestinal tract undergoes necrosis due to insufficient blood supply caused by strangulation by the hernial ring; in a few cases, although the hernial ring is large, the fallen intestinal tract undergoes necrosis due to prolonged stimulation by the contents (even putrid contents). Based on the circumstances, we have used surgery to treat many cases of intestinal necrosis caused by umbilical hernia in pigs, with good results,

Hollow bricks for pig beds: pigs avoid rheumatism and grow fatter and stronger
At present, pig production in China is mainly small-scale or free-range, and pig-raising conditions are relatively poor. In northern China, temperatures from December to February of the following year are very low, only a few pig houses have heating, and the vast majority have low indoor temperatures, with pigs lying directly on concrete floors that are both damp and cold, causing a high incidence of rheumatism in pigs (such as lameness and paralysis), which affects weight gain speed and feed conversion rate. In particular, paralysis in farrowing sows leads to culling, causing great losses. In recent years, the author has used the method of laying hollow bricks as pig beds to prevent rheumatism in pigs, with excellent results. By September

Analysis of the Causes of Tail Biting in Pigs and Control Methods
In large-scale, intensive pig production, it is common to see nursery and finishing pig herds develop the bad habit of biting each other's tails. Tail biting in a herd not only increases feed consumption, affects growth and makes management more difficult, but in severe cases can also lead to injury and bacterial infection in the pigs. So what causes tail biting in pigs? Based on summaries, it is related to the following factors: (1) Management factors: (1) insufficient feeding, not enough feeding spaces, unreasonable trough design, etc., causing pigs to go hungry; (2) poor water quality, insufficient or

How to treat pigs with foot rot (bush legs)
Examine the pig's feet while it is lying down. Because the blood supply to the infected tissue is poor, the antibiotic dose should be increased and the duration of treatment extended in order to achieve a therapeutic effect. The following antibiotics can be chosen for treatment: lincomycin, 11 mg per kg of body weight per day; oxytetracycline, 25 mg per kg of body weight per day; amoxicillin, 15 mg per kg of body weight per day, injected continuously for 5 to 7 days. If there is no improvement after three consecutive days of medication, another antibiotic should be used instead. Complete recovery takes 3 to
