The video ‘How to muscle score beef cattle’ runs for 23 minutes and was produced in 1993. The video covers the following areas:

• There are five different muscle scores: the highest score (A) represents the most muscled animal; the lowest score (E) represents the least muscled animal.
• The same muscle scoring principles are applied to female cattle, steers and bulls.
• The skill of muscle scoring is explained.
• Muscling is an economically important characteristic.
• Muscling can be improved by breeding, with consideration to growth rate, fertility, calving etc.
