What are the precautions for feeding pigs soybean cake?
Soybean cake is a high-quality feed for pigs, containing about 40% crude protein and 6%-8% fat; its crude fiber content is very low, only below 5%. In the protein, lysine accounts for 2.9%, while methionine and tryptophan each account for 0.6%. Its amino acid content is higher than that of any other plant-based protein feed, making it the most valuable among plant feeds. Soybean cake has an aromatic fragrance, 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 powder should be supplemented. The amount of soybean cake used must not be too much, generally accounting for about 15% of the daily ration.

What nutritional roles does protein play in pigs?
Protein is the material basis of all life. Protein is the main component of all cells, accounting for 15%-21% of the body. The muscles, nerves, connective tissue, blood, etc. in the body all have protein as their basic component. The hair, horns, feathers, hooves, etc. on the body surface of livestock are composed of keratin. Enzymes, hormones, antibodies in the body and products such as milk, meat, eggs and hair all contain protein components. The proteins of the organs and tissues of the livestock body are constantly renewed during metabolism. According to research, half of the protein in the body is renewed within 6-7 months. Therefore, even

What to Do About Pigs' Bad Habits? Introduction to Clever Solutions
Pen escaping: Trim the upper eyelashes of a pen-escaping pig short, and trim them again once they grow long. This way, when the pig raises its head to escape the pen, its eyes will be irritated by wind, light, and dust, creating a sense of fear. After several times, the pig will no longer escape the pen. Wall chewing: Pigs often chew walls because of insufficient salt intake. Generally, the salt content in the diet of 60-90 kg fattening pigs should reach 0.25%, and the salt content in the diet of breeding boars should reach 0.35%. Biting and fighting: When pigs from different pens are housed together, biting and fighting often occur. If

Swine rheumatism is a type of surgical disease in pigs.
[Cause] Swine rheumatism occurs in cold and damp weather. Because the pigsty is dark and damp, with poor warmth retention and no clean bedding straw, the pig is exposed to attack by wind and cold, or stimulated by ice and snow, rain, and dampness, or triggers such as insufficient exercise and sudden feed changes cause the disease. [Symptoms] This disease often affects the muscles and joints, and usually comes on suddenly. It first appears in the hind limbs, then soon spreads to the front limbs, or the affected area often shifts, with alternating lameness. The muscles or joints of the affected area are painful. On palpation, the surface of the affected muscles is hard and not smooth. The joints

What happens when pigs experience stress from the environment
Stress is the sum of non-specific response reactions produced by an organism to various extraordinary stimuli. Environmental factors that can cause stress responses in the body are called stressors or stress factors. After pigs are stimulated by environmental factors, they all produce reactions, but the forms of reaction differ. General stimuli cause specific reactions in the body, such as pigs huddling together when it is cold in winter, and dispersing when it is hot in summer. However, some stimuli (stressors) not only cause specific reactions in the body but also cause non-specific reactions, namely stress responses, which manifest as

What are the prevention and treatment methods for fractures and dislocations in pigs?
A crack in a bone caused by external impact is called a fissure fracture (also known as incomplete fracture), while a break is called a fracture (also known as complete fracture). When the 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 joint surfaces cannot contact each other at all, it is called a complete dislocation; when the two joint 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.

A Detailed Explanation of the Harm of Mycotoxins to Pigs and Prevention Methods
After pigs eat corn contaminated with mycotoxins, symptoms such as stunted growth and development, reproductive disorders (dead sperm, infertility, stillbirth, etc.), emaciation, and reduced disease resistance appear, causing relatively large economic losses to pig production. To make it easier for breeders to judge and prevent and control the problem in time, the symptoms of poisoning by different mycotoxins and their prevention measures are introduced below. I. Harm of mycotoxins to pigs 1. Aflatoxin. It is the most harmful toxin in pig production. (1) It is the strongest immunosuppressant. After pigs eat feed contaminated by it, the immune system is first

Diagnosis and Treatment of Alcohol Distiller's Grains Poisoning in Pigs
He, a villager from Shilai Village, Yuping Town, fed his pigs a mixture of leftover distiller's grains from liquor production, restaurant leftovers, and some rice bran. In early August 2006, 36 pigs developed distiller's grains poisoning, 4 died, and of the remaining 32, 31 recovered after treatment, a cure rate of 96%. Clinical symptoms: the sick pigs showed reduced or absent appetite, digestive dysfunction, rough coat, chronic emaciation, anemia, edema, labored breathing, and limb paralysis. Five severely poisoned pigs had decreased body temperature, with 1 of them below 36 degrees C. Some showed excitement, unsteady gait, mental confusion or falling down, collapse, and then lay on their sides unable to rise.

Adding seasonings to pig feed can make pigs grow faster
Pigs have a well-developed sense of taste, with more than 15,000 taste cells in the oral cavity. Adding seasonings (flavoring agents) to feed can promote the secretion of the salivary glands, gastric glands and pancreas, increase feed intake and promote growth and development. The following seasonings are currently used more often.

Disease Occurrence Patterns and Prevention Methods for Pigs at Different Rearing Stages
Disease Occurrence in Pigs at Different Rearing Stages Incidence Rates of the Three Major Infectious Diseases of Pigs Hog cholera, swine erysipelas, and swine pasteurellosis are collectively known as the three major infectious diseases of pigs. In China, the overall mortality rate of affected pigs accounts for about 8% of the total reared population, and even in areas with relatively good prevention and control, pig mortality stands at 5%. Therefore, the level of pig disease prevention and treatment should be improved. If the overall pig mortality rate could be reduced by one percentage point each year, that would be equivalent to an additional 5 million pigs sent to market - what a tremendous amount of wealth that represents. According to relevant statistics, among the causes of pig deaths, those caused by
