How to prevent runt pigs? A detailed explanation of practical technical points
There are many reasons for the formation of runt pigs, including congenital factors such as inbreeding or early mating and improper feeding and management of pregnant sows, which result in low birth weight and weak vitality of piglets; there are also acquired factors, such as insufficient milk from the sow, malnutrition, early weaning, delayed supplementary feeding, severe nutritional deficiency and diseases. The following measures can be taken to resolve runt status and fatten them. (1) Deworming and clearing the stomach. When there is no disease and the weather is clear, skip one feeding at noon, and at 8-9 o'clock in the evening when the stomach is empty, use 15-20 millig

Reasons why pigs eat but do not put on fat, and how to solve it
During the growth process of pig farming, some pigs eat but do not put on fat. What is the reason? The causes and treatment methods are described below: Look for causes. First, check for congenital causes, such as inbreeding or breeding a young sow too early. Second, check for acquired causes: insufficient mother's milk, unreasonable grouping after weaning, with the big bullying the small; chronic diseases, such as anemia, white scour of piglets, and internal and external parasitic diseases; surgical diseases, such as intestinal adhesions after castration; unreasonable feed formulation, such as protein deficiency and trace element deficiency, etc., all of which can cause slow or stopped growth in pigs.

What do pigs eat to fatten quickly? Adding seasonings to pig feed works well
Pigs have a well-developed sense of taste, with as many as 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. At present, the following seasonings are used more often: Sweet seasonings. Adding 0.05 g of saccharin per kg of finishing pig diet can increase the average daily gain of pigs by 6.4% and reduce feed consumption by about 5%. Adding 60 ppm of saccharin to the diet of lactating sows can prevent anorexia and excessive

What are the prevention and treatment methods for clonorchiasis in pigs?
1. Pathogen: caused by Clonorchis sinensis parasitizing the bile ducts of the liver. Besides pigs, dogs, cats and humans can also be infected. Clonorchis sinensis is a relatively small and transparent fluke, 10-20 cm long and 2-5 mm wide, shaped like a willow leaf. The eggs are passed with the feces, are swallowed in water by the first intermediate host, freshwater snails, and develop inside the snail, emerging as cercariae. The cercariae enter the body of the second intermediate host, freshwater fish, and form metacercariae, and the final host (pigs, etc.) becomes infected by eating undercooked fish containing metacercariae. In the pig's small intestine, the metacercarial wall membrane is digested

What role do carbohydrates play for pigs? What pig farmers need to know
Carbohydrates are composed of three elements: carbon, hydrogen and oxygen. They are the main component of plants, accounting for about 70%-80% of all nutrients in plants, and are the main energy source in pig feed. After carbohydrates enter the pig's body, they are transformed into energy through a series of changes, providing heat energy for the pig's various life activities. The carbohydrates remaining after meeting daily energy consumption can be converted into fat in the pig's body and stored as an energy reserve, to be used when hungry. The pig's fat and leaf fat are this reserve of surplus energy. Pigs have a strong ability to convert carbohydrates eaten into fat, and when a large amount of carbohydrates is eaten, body fat increases quickly as well, so feeding pigs with feed rich in carbohydrates (such as corn, rice, sweet potato, potato) makes it easy to convert into body fat. When raising lean-meat pigs, carbohydrates should be supplied reasonably, especially in the late fattening stage, when the feeding amount of such feed should be appropriately reduced to prevent the pig from becoming too fat.

Why is feeding pigs dry feed good? An analysis of the reasons
Many pig-farming practices have shown that feeding pigs thin, watery feed seriously affects digestion and absorption, leading to dry dung, red eyes, reduced frequency of defecation, weakened intestinal peristalsis, and slow pig growth. It follows that pigs are best fed raw dry powder feed, allowing them to eat freely, with a separate water trough for drinking, or fed a thick mash with a feed-to-water ratio of 1:1. This prevents the feed from freezing in winter and spoiling in summer, and lets the pigs eat their fill and grow fast.

A Detailed Explanation of Pigs' Mineral Nutrition Requirements and Supplementation Methods
It has now been proven that pigs have about 40 kinds of essential mineral elements, which are divided into two major categories according to their content in the pig's body: macroelements and microelements. Elements with a content of 50 mg/kg or above are macroelements, mostly expressed as a percentage; elements below 50 mg/kg are microelements, mostly expressed in mg/kg. Pigs need at least 14 inorganic elements, including the macroelements calcium (Ca), phosphorus (P), sodium (Na), chlorine (Cl), potassium (K), sulfur (S), magnesium (Mg) and

Biotech pigs capable of producing a cerebral thrombosis treatment drug have been successfully bred by South Korean scientists
South Korean scientists have successfully bred "biopigs" that produce a cerebral thrombosis (cerebral hemorrhage) treatment drug through their urine. The South Korean Rural Development Administration recently stated: "By injecting the genetic gene for treating cerebral thrombosis (TPA) into pig fertilized eggs, we successfully bred 4 pigs that can excrete cerebral thrombosis treatment substances through their milk and urine." South Korea has become the world's second country after the United States to breed, through genetic modification, animals capable of producing cerebral thrombosis treatment substances. The United States, in 1997, through genetic modification technology,

Glässer's disease is a bacterial disease of pigs
Glässer's disease, also known as fibrinous polyserositis and arthritis, is caused by a Gram-negative coccobacillus and presents as sporadic polyserositis and arthritis. With the development of the global pig industry, the application of intensive farming techniques and highly dense rearing, as well as the emergence of new respiratory syndromes and other factors, the disease has become increasingly prevalent and its harm increasingly serious. In the past two years, reports of Haemophilus parasuis causing polyserositis and arthritis in pigs on pig farms in China have been common, especially on large-scale pig farms where, after being affected by blue ear

5 Key Links That Must Be Grasped to Raise Pigs Well
Developing pig farming is highly practical and delivers quick results, making it a good path for farmers to increase income and become wealthy, but to achieve good returns the following five key links must be grasped: First, seize the opportunity. When developing pig farming amid constant market fluctuations, attention should be paid to four periods, namely: the trough period, the development period, the peak period and the decline period. The trough period in the fluctuations of the live pig market is the best time for pig farmers to enter, as the prices of piglets and breeding pigs are low at this time, and the input cost of developing pig farming is relatively low; when the live pig market gradually
