In finishing pigs aged 90-100 days (13 weeks old), respiratory diseases such as cough, gasping, and respiratory difficulties, and digestive tract diseases such as diarrhea, feces, and bloody stools are the main clinical symptoms. The death of the pigs was obvious, and only the performance of the comprehensive disease characterized by an increase in feed-meat ratio, a reduced growth rate, an extended slaughter time, and a decreased slaughter rate was observed. The problem arises and is therefore customarily called the "13-week-old wall." "13-week-old wall" mechanism The reason for the appearance of a “13-week-old wall†in pigs and the decrease of antibodies to viral diseases such as blue-ear disease, swine fever, and pseudorabies antibodies in pig herds, some of the viruses became active, and immunosuppression caused the respiratory pathogens frequently found in pig farms. Such as Mycoplasma pneumoniae, Mycoplasma nasalis, Actinobacillus pleuropneumoniae, Pasteurella multocida, Borrelia septicum, Streptococcus, and intestinal diseases such as Lawsonia intracellularis (Ileitis), Treponema pneumoniae (pig Blood dysentery, E. coli, etc. Clinical and Pathological Features of "13-week-old Wall" 1, manifested as severe respiratory disease symptoms Infection with pneumonia caused the occurrence of respiratory diseases such as cough, gasping, and respiratory distress. After dissection, there was a "meat-like" lesion in the heart and leaves of the lungs; the pigs infected with pleuropneumonia experienced high fever, cough, and gasping. "Respiratory, sudden death, mouth foam and blood, anatomy see lung adhesions, bleeding, abscess, etc.; pigs with atrophic rhinitis have sneezing, tear spots, nose bending, nasal atrophy and other symptoms. 2, the performance of severe diarrhea dung, feces, bloody stools and other gastrointestinal symptoms Pigs infected with ileitis were significantly thinner and grew slower than normal pigs. The slaughter time was postponed by 10-15 days. Clinically, the pigs were constantly pulling out thin and soft stools. Undigested feed was sometimes found in the feces. After the anatomy, the ileum was found to be "sausage-like". The thickening of the intestinal wall, the narrowing of the intestine, and the appearance of the brain surface were "brain-like". "13-week-old wall" main influence on the pig industry The main hazard of the 13-week-old wall is not characterized by the high mortality rate of growth and fattening, but mainly chronic consumptive respiratory diseases and chronic wasting intestinal infections, causing feed wastage and higher feed-to-fat ratios for grow-finishing pigs. Slow growth rate, poor uniformity of pigs, extended slaughter time, and low meat rate slaughtered. Therefore, for a long period of time, it has not caused the attention of pig producers in China.
