- - - - Pregnant cow
        
        Estimate stage of pregnancy
        
        Compare with the interval from the last service
        
        Cows (repeat breeders/anestrus) =pregnant
        
        Good index of the accuracy of the records = the relationship between stage of pregnancy and interval since breeding frequently
      - Not pregnant cow
        
        Determine the stage of involution of the reproductive tract
        
        Examiner search for signs of
        
        salpingitis
        
        metritis
        
        pyometra
        
        cervicitis
        
        vaginitis
      - Not pregnant cow (but show evidence of ovarian activity)
        
        Estimate the stage of the oestrous based on
        
        size and consistency of the follicle and corpus luteum
        
        consistency of the uterus
        
        cows considered anestrus frequently have corpus luteum, suggesting silent or unobserved estrus
- - - - Collecting uterine swabs for culture and sensitivity
      - Determine the presence of pathogenic organism in the uterus and their sensitivity to the antibiotics
      - Advantage
        
        Making an accurate diagnosis
        
        Proper treatment can be selected
  - - - To confirm presence of endometritis
      - Endometritis; important cause of infertility
  - - - Test performed on blood should include
        
        Haemoglobin
        
        Protein
        
        Calcium
        
        Phosphorus
        
        Vitamin A
      - Phosphorus deficiency can cause infertility
    - - Check for
        
        Infectious bovine rhinotracheitis
        
        Bovine virus diarrhea
        
        Shipping fever (PI-3)
