How to Treat Stunted Pigs: An Introduction to Integrated Traditional Chinese and Western Medicine Therapy
Stunted pigs are underdeveloped piglets with stunted growth, also called "little old pigs", "runts", or "hedgehog pigs". These pigs only eat feed without gaining meat, causing great waste of manpower, feed, and pen space in pig production as well as economic losses. 1. Symptoms: Stunted pigs have rough, disordered hair, are thin and small in build, with arched backs and sagging bellies, large heads and thick tails; some are anemic, eat normally but grow slowly, and some have alternating constipation and diarrhea; scabies or internal and external parasites are often present. 2. Causes

Detailed Explanation of Surgical Treatment Methods for Gastric Perforation in Pigs
Cases of gastric perforation in pigs are not commonly seen in clinical practice. The author has encountered two cases: one died due to ineffective treatment following a misdiagnosis, and was confirmed as gastric perforation upon postmortem examination; the other recovered after surgical treatment. The surgically cured case is reported as follows: 1 Clinical Symptoms A breeding Duroc boar raised by a specialized pig farming household, 6 months old, weighing approximately 75 kg, suddenly became ill on March 23, 2004, showing depression, reduced appetite, abdominal pain and restlessness, frequently lying down, and occasionally vomiting. Palpation of the abdomen elicited a pain response, and the abdominal

How to raise first-time mother pigs? Master these breeding secrets
1. Nutritional regulation during the growing period. For young sows (two-way crossbreeds), starting from 30 kg body weight, each kg of compound feed in the diet should contain 13 megajoules, 16% crude protein, 0.8% lysine, 0.75% calcium, and 0.65% phosphorus; do not restrict feed intake, and let them eat as much as possible. Starting from 45 kg body weight, increase the calcium and phosphorus content by 0.1% each. At 150 days of age, when the young sow weighs about 80 kg, control feed intake to 2.3 kg to 2.5 kg per day. For native-breed young sows, the calculated body weight should be 2 kg to 3 kg less.

How to Give Pigs Injections for Disease Prevention? A Detailed Guide to the Correct Method
Swine fever lapinized attenuated freeze-dried vaccine prevents swine fever. According to the dose shown on the bottle label, under sterile conditions, add sterile physiological saline and dilute each portion into a 1 ml suspension, then inject subcutaneously or intramuscularly at the pig's hindquarters or behind the base of the ear. Regardless of the pig's size, the dose is 1 ml. If there is already an outbreak near the pig farm, two immunizations are preferable, the first at 21-30 days of age, and the second after weaning (around 65 days of age). Pregnant sows can also be injected. Generally, immunity develops 4 days after injection, and the immune period lasts more than 1 year.

Analysis of Why a Shorter Rearing Period Is Better for Growing-Finishing Pigs
Under good feeding and management conditions, lean-type pigs generally need 100 to 120 days to go from 20 kg to the market weight of 100 kg. In China's intensive and standardized pig farms, it generally takes about 110 days to go from 20 kg to 100 kg, and the age of pigs from birth to the market weight of 100 kg is 160 to 180 days, greatly shortening the finishing period. The benefits of this are as follows. 1. High daily gain and high feed efficiency. Lean-type pigs grow quickly. If a complete feed with comprehensive nutrition is provided, their productivity potential can be fully

Prevention and Treatment of Rheumatic Arthritis in Pigs in Winter
Rheumatic arthritis in pigs occurs mostly in the more mobile joints such as the shoulder, elbow, hip, and knee, and is often symmetrical, though it can also be migratory. The joints of the spine may also be affected. Acute articular rheumatism presents with symptoms of acute synovitis, with joint swelling, fluid accumulation in the joint cavity, and fluctuation on palpation. When standing, the affected limb is often flexed, and during movement the pig mainly shows lameness, often accompanied by systemic symptoms. When it becomes chronic, symptoms of chronic arthritis appear, with proliferation and thickening of the tissue surrounding the synovium, thickening of the joint, and restricted movement. The affected limb is difficult to lift, movement is slow, the stride is shortened, and the lameness lessens or disappears as the amount of exercise increases.

How to Treat Stunted Pigs? Detailed Explanation of 6 Treatment Methods
Pig farming is a good way for farming families to get rich. A pig that has been raised for a long time without growing is called a "stunted pig," mostly due to parasites or gastroenteritis. Below is an introduction to effective remedies for treating "stunted pigs": 1. Deworming For pigs weighing 10 kg to 15 kg, use 40 trichlorfon tablets, dissolve in half a tank of water (about 2% concentration), and wash the pig's entire body to kill external parasites (treating mange), then use deworming powder or veterinary trichlorfon to eliminate internal parasites. 2. Bloodletting You can prick the vein under the pig's belly to release some stagnant blood to promote

What is the appropriate stocking density for raising pigs?
The stocking density of pigs refers to the pen area occupied by each pig, usually expressed as "sq m/pig". Stocking density indicates how densely the pigs are housed in the barn. Stocking density has a great influence on the air environment inside the barn. If too many pigs are housed, more heat is released, which helps keep the pig barn warm in winter but is unfavorable for heat protection and cooling in summer; it increases the levels of harmful gases, water vapor, dust and microorganisms in the barn, and also makes fighting among pigs frequent, affecting feed intake and rest. If too few pigs are housed, then

Points to note when raising pigs in summer: do not throw cold water on the pigs
In summer, when the temperature is high, pigs often pant loudly from the heat. Some farmers, worried that the pigs will fall ill from the heat, throw cold water on the pigs, hoping to cool them down and make them feel more comfortable, not realizing that this is harmful and does no good. Pigs pant from the heat because their sweating is poor, so the heat in their bodies cannot be released for the time being. If cold water is thrown on a pig at this time, the strong cold stimulation makes the sweat pores all over the pig's body contract sharply, the release of body heat is blocked, and the body temperature instead rises abruptly; in mild cases the pig develops a high fever and inflammation of the lungs, and in severe cases it

What are the pathological changes of aflatoxin poisoning in pigs?
In acute cases, anemia and hemorrhage occur, with massive bleeding in the thoracic and abdominal cavities, and petechial spots often on the serous membrane surfaces. Hemorrhage occurs in the subcutaneous muscles in front of the thigh and under the scapula. The liver is enlarged with bleeding points. In the part of the liver adjacent to the serous membrane there are pinpoint or ecchymotic hemorrhages, obvious hemorrhages are common on the epicardium and endocardium, and hemorrhages are often present throughout the body muscles. In chronic cases, there is proliferation and sclerosis of the liver bile ducts, yellow fatty degeneration of the liver, white spots or necrotic lesions on the liver surface, and effusion in the thoracic and abdominal cavities. The renal cavity is pale and swollen. The systemic lymph nodes are congested and edematous.
