  1. Managing Cows through Body Condition Scoring

  2. Condition Score 3 Outline of spine, ribs and hip visible. Slight muscle atrophy

  3. Condition Score 5 Outline of spine, 1-2 ribs and hip bone slightly visible. No fat in flanks or brisket

  4. Condition Score 7 Brisket, twist & flanks full. Some fat in udder & around tail head

  5. Probability of cycling by thebeginning of the breeding season Probability Pruitt and Momont

  6. Probability of pregnancy during a 60-day breeding season Probability Pruitt and Momont

  7. Probability of conceiving in the first 21 days of the breeding season Probability Pruitt and Momont

  13. Summary • Body Condition Scoring is a good management tool for monitoring the nutritional status of beef cattle. • Most reproductive failures in beef females can be attributed to improper nutrition.
