1 Pig Stress Syndrome is a group of symptoms that are characterized by stress factors, abnormally high frequency of producing white color, loose texture and exudation of muscles, and sudden death of other lesions.
1.1 PSE meat: due to pre-slaughter transport, crowding and binding, heat, electricity and other stimuli, manifested as muscle rigidity, the body lacks oxygen, excessive glycolysis of glycogen, pork color is pale, loose texture and juice oozing, often occurs in Leg muscles, longissimus dorsi, semitendinosus, semimembrane, biceps femoris.
1.2 DFD meat: Due to the long pre-slaughter fasting time, sugar depletion or less storage of living sugar, the process of glycolysis of glycogen is mild, slow, dry muscle sections, rough texture, dark color.
1.3 adult pig back muscle necrosis: mainly occurs in 75-100kg adult pigs.
1.4 PSS (heart dead pig): 3-5 months old pigs are the most common, pale myocardium, gray or yellowish-white stripes or spots, myocardial degeneration.
1.5 Acute necrotizing myositis in pigs: The reason is poor adaptability to transport stress stimuli and muscle necrosis, autolysis and inflammation.
2 Gastrointestinal ulcers are caused by chronic stress stimuli such as feeding crowds, panic attacks, and adrenal hyperactivity caused by feeding compound feeds alone, resulting in hyperacidity and damage to the gastric mucosa.
3 Colibacillosis Escherichia coli becomes a pathogenic microorganism when the body's resistance is reduced under stress.
4 Pig bite tails can cause biting tails in pigs under conditions of high concentration, drinking, and insufficient feed.
5 Turkic syndrome is characterized by sudden death when no symptoms are seen when apprehended or frightened.
6 Breast milk puerperal period Anorrhagic syndrome occurs after childbirth with no milk or less milk, loss of appetite, fever and rigidity, swollen breasts, and acute symptoms of genital discharge.
7 Pathogens transporting pathogenic bacteria Haemophilus parasuis and Haemophilus parahaemolyticus are mostly induced by transport fatigue and are characterized by multiple serositis.
8 Transport heat occurs in overloaded and poorly ventilated compartments. The breathing of the sick pigs is accelerated, the skin temperature rises, the mucous membranes turn purple, and the body trembles. The necropsy shows changes in lobar pneumonia, widened lobules, serous infiltration, and sometimes Acute enteritis.
