Pigs rooting at the pen and gnawing at soil are not just mischief; the reasons behind it need to be understood
Pigs rooting at the pen and gnawing at wood and soil are not just playing around; it is an abnormal phenomenon that affects the pigs' normal growth and development. The main causes are: first, growing-finishing piglets lack the mineral feed needed for growth; lactating sows and pregnant sows use their own mineral elements for the normal growth of suckling piglets and fetuses, and the minerals in the feed are hard to meet the demand. Second, the feeding is unreasonable: too little feed is given, the pigs do not eat their fill, and no water is provided with the feed. Third, sick pigs also show pen-rooting and gnawing at wood and soil. Prevention methods: first, pay attention to the feed mixing ratio and add mineral

What are the main causes of sudden death in pigs?
In the process of pig production, many problems often occur. Some problems are fleeting, some occur from time to time, and some emerge one after another. As managers and technicians of a pig farm, one should learn to let go of the "fleeting ones," pay attention to the "recurring ones," and focus on solving the "endless ones." The problem of sudden death in pigs belongs to the "recurring ones," which often puzzles farmers and requires the attention and concern of managers and technicians. There are many cases of sudden death in pigs, and the diseases

What are the effective treatments for rectal prolapse in pigs?
Pig rectal prolapse is divided into two cases: the first is that the sick pig can recover on its own when standing, but the rectum can protrude again during defecation; the second is that the sick pig cannot reduce the prolapse on its own when standing. The treatment method is to wash the affected area with a warm 0.1%-0.2% potassium permanganate solution, dry it with sterile gauze, and then apply an appropriate amount of snail meat paste to the affected area. The specific method for making snail meat paste is: wash the snails clean, remove the shells and take the meat, wash the snail meat and the tool used to mash the snail meat with a 0.2% potassium permanganate solution, and then mash the snail meat into a paste.

What are the precautions for feeding pigs soybean cake?
Soybean cake is a high-quality feed for pigs. It has a fragrant aroma and pigs love it very much, but it lacks vitamin D, carotene and calcium. Some carrots and mineral feeds such as bone meal and stone meal should be supplemented. The amount of soybean cake used must not be too much; generally about 15% of the daily ration is appropriate, and more than 20% often causes diarrhea in pigs. Therefore, when using soybean cake to feed pigs, it must be used scientifically and fed in appropriate amounts so that it can play its role as a high-quality concentrated feed; otherwise, it will have the opposite effect.

What are the prevention and treatment methods for moldy feed poisoning in pigs?
1 Main pathogens and their harm Currently, more than a hundred mycotoxins are known, mainly aflatoxin, ergot toxin, zearalenone, etc. Among them, aflatoxin is the most serious toxin harming pig production. Aflatoxin is a hepatotoxin. When pigs eat feed contaminated with aflatoxin, it reduces liver function, causes decreased bile secretion, and at the same time reduces the activity of protease and lipase secreted by the pancreas, affecting the absorption and utilization of protein and fat in the feed; it is also a relatively strong coagulation factor inhibitor

Diagnosis and Prevention and Treatment Methods for Chronic Mycotoxin Poisoning in Pigs
A disease characterized primarily by acute conjunctivitis and diarrhea in finishing pigs and sows occurred at a large pig farm, with a morbidity rate of 20%, a mortality rate of 0.5%, and a culling rate of 1.2%. Based on clinical symptoms, pathological necropsy findings, and medical history investigation, it was diagnosed as mycotoxin poisoning in pigs. The report is as follows. 1 Clinical symptoms: Finishing pigs and sows developed acute conjunctivitis, with eyelid swelling, conjunctival hyperemia, photophobia, and mucopurulent discharge. In cases with a longer disease course, corneal opacity and blindness occurred, along with diarrhea; the feces changed from initially gruel-like to watery, and finally to thin feces with mucus

Detailed Explanation of Cross-Infection and Safe Injection Issues in Pigs
(1) Sterilization of vaccination equipment. Syringes, needles and other vaccination equipment must be strictly sterilized and disinfected according to requirements. (2) One pig, one needle. Strictly guard against the one-needle-to-the-end injection method. It is best to use one pig, one needle, changing the needle for each pig injected. (3) Order of emergency vaccination. During emergency immunization, vaccination should be carried out in the order of relatively clean herds; assumed healthy herds; threatened herds; and affected herds. Within an affected herd, proceed in the order of asymptomatic; mildly symptomatic; and severely symptomatic. (4) Safe and scientific injection issues. Intramuscular injection at the side of the neck behind the ear.

High temperatures trigger heat stress in pigs, affecting their physical health
The high-temperature environment from June to September each year disrupts pigs' sex hormone secretion, throwing their normal estrus mechanism out of order, so that estrus symptoms become inconspicuous or the animals do not come into heat at all; high temperatures make pigs devote most of their energy to resisting heat stress, correspondingly weakening their other bodily functions, and for lactating sows and fattening pigs that need to eat large amounts of feed, this leads to insufficient nutrition and the phenomena of low milk output and slow growth; high temperatures make heat dissipation from the boar's testicles difficult, intensify sperm metabolism and shorten sperm lifespan, so that the motility of ejaculated sperm decreases or the sperm even die; high temperatures also increase the death of newly fertilized eggs and make implantation of the fertilized eggs more difficult, thereby lowering the conception rate of summer breeding.

What are the precautions for feeding pigs with distillers' grains? Farmers should keep them in mind
Distillers' grains are divided into baijiu distillers' grains and beer distillers' grains. Baijiu distillers' grains have 32 percent dry matter, 3.36 MJ per kg digestible energy, and 7.5 percent crude protein. Beer distillers' grains have 14 percent dry matter, 1.43 MJ per kg digestible energy, and 3.6 percent crude protein. Whether baijiu distillers' grains or beer distillers' grains, they must be fed fresh; if piled up for a long time, they will become moldy and spoiled. If there is any left over, it can be put into a large vat, trampled down firmly, and soaked in water. Pregnant sows and lactating sows are not suitable for feeding, to prevent miscarriage, stillbirth, and so on. For meat pigs, it generally does not exceed the daily ration

Sarcoptic mange in pigs is common in winter, pig farmers should take preventive measures
Sarcoptic mange in pigs, also called scabies, commonly known as mange, is caused by Sarcoptes scabiei mites parasitizing in the pig's skin, causing skin lesions such as red spots, pustules, crusts and fissures. It is characterized by intense itching, restlessness, reduced appetite, slow growth and decreased feed conversion, and is one of the diseases that seriously harm pig production. It is widespread in some farms and difficult to cure. The severity of its clinical symptoms is related to the pig's resistance. When climatic conditions are suitable and feeding management is good, the pig's resistance is strong and there are generally no obvious symptoms. In the high-temperature summer season, frequently washing the pig pens and pig bodies helps
