- - - - Milky diet
      - Lactose easily digestible
      - Palatable and digestible
      - Fresh food and clean feeders
  - - - Overcrowding, not enough feed space
      - Poor hygiene, disease
      - Cold or poor ventilation
      - Incorrect ration
    - - Produce less heat
      - Eat less food
      - Prone to disease
      - Less able to compete
- - - - Sudden death, ataxia, recumbency, paddling, pyrexia
      - Treat with penicillin + NSAIDs + water
        
        Control with ventilation, stocking density, strategic antibiotic use in feed or water
      - Strep suis type 2
        
        Systemic illness
        
        Microbiology of heart blood, joint fluid, meningeal swab
        
        Joint swelling, lethargy, inappetence, seizure, nystagmus, sudden death
        
        PME: Fibrin-polyserositis, endocarditis
    - - Pigs in good condition but lose weight then yellow scour before death
      - PM signs: haemorrhagic, oedematous mesentery, yellow scour, enlarged liver and spleen, lung congestion and turkey egg kidney
      - 3-4 weeks after weaning
      - Nursing/ symptomatic care
    - - Ddx: CSF
      - Most affected pigs die, can vaccinate PCV-2
      - Massive dark black skin lesions (scrotum), ear tips may drop off
    - - E. coli, Salmonella, PCV-2
      - Swabs from untreated pigs for bacteriology and C&S
      - 7-10 days post weaning
      - Bowel oedema
      - Antibiotics in feed and zinc oxide in ration
- - - - Stomach becomes less acidic
      - Absorptive surfaces of the gut decreases
      - Malabsorption occurs as gut not ready for cereal digestion
      - Protective immune factors in milk removed
    - - Malabsorption
      - Diarrhoea and dehydration
      - Gut inflammation
      - Systemic disease
    - - Average intake less than 100g over first 48hrs
      - Maintenance energy requirements not met until 3 days
      - Only 50% eat within first 24hrs of weaning
