     Pictures of 3 TH Calves (quite graphic)

     Matings with bulls that are documented TH carriers will result in one of three outcomes:
     1. The calf will be born TH-free; neither afflicted nor a carrier.
         The down side is there is currently no test  that distinguishes this outcome from #2.
     2. The calf will be physically fine, but a TH carrier.
     3. The calf will be afflicted with the characteristics described below.
         TH manifests as:
         1. lesions included bilaterally malformed or absent tibia and abdominal hernia in all animals
         2. a long shaggy hair coat
         3. retained testicles in males
         4. meningocele, which are protrusions of the coverings of the spinal cord or brain.
