Body condition score

Body condition score is the main driver of breeder performance. Body condition score is a visual assessment of overall fleshing, including fat and muscle tissue. Body condition score is usually described on a 1–5 scale. The scale can be categorised as follows:

1.  Poor

  • no fat cover

  • very low level of muscle tissue

  • skeletal definition very pronounced.

2.  Backward store

  • light muscle tissue cover

  • skeletal definition pronounced, particularly the backbone and rear ribs.

3.  Moderate

  • a reasonable degree of muscle tissue present but no significant levels of fat

  • neither the backbone nor ribs are prominent

  • pins are filled out and hip remains prominent.

4.  Forward store

  • even coverage of muscle and fat

  • skeletal definition smoothly rounded.

5.  Fat

  • significant levels of fat

  • skeletal definition lost.

Poor and backward store body condition is one of the main impediments to resumption of cycling in breeders. Cows need to have a body condition of score of three or greater at calving to have a chance of reconceiving and calving within 12 months.

Body condition score can be managed using the following strategies, in order of importance:

  • stocking rate
  • weaning
  • supplementation
  • pregnancy testing and breeder segregation.
