Cattle have a large number of muscles, with over a hundred different muscles making up the beef carcass. These muscles have different properties which affect processing characteristics and consumer acceptability. For example, the pre-slaughter growth rate of beef cattle can affect meat tenderness.
| Characteristics | Values |
|---|---|
| Number of muscles in a beef carcass | Over 100 |
| Muscles in the compartment of the stifle joint | 4 |
| Muscles that affect meat tenderness | Pre-slaughter growth rate |

What You'll Learn
- The beef carcass is made up of over 100 muscles
- Tenderness of meat is affected by the pre-slaughter growth rate of cattle
- Double muscling in cattle is associated with higher blockiness
- The stifle joint is extended by four muscles
- Research is being conducted to profile the physical and chemical characteristics of beef muscles
The beef carcass is made up of over 100 muscles
There has been a trend to separate muscles based on these characteristics to better market them. The majority of cuts found in the retail meat counter are boneless, which means that butchers need to have a good knowledge of the musculature of the beef animal.
Research has been conducted to profile the physical and chemical characteristics of beef muscles to more fully realise their value. This information will help processors to develop and prepare new products based on the inherent properties of each muscle.
The pre-slaughter growth rate of beef cattle can also affect meat tenderness.

Tenderness of meat is affected by the pre-slaughter growth rate of cattle
The beef carcass is made up of over a hundred different muscles. These muscles have different properties which affect processing characteristics and consumer acceptability. Tenderness of meat is affected by the pre-slaughter growth rate of cattle. For example, DM animals had the lowest shear force values at a live weight of 300-350 kg, while values were higher at 530-560 kg.
There are four muscles within the stifle joint compartment: vastus lateralis, vastus medias, vastus intermedius and the straight muscle. These muscles extend the stifle joint and flex the hip joint. The popliteal muscle flexes the stifle joint and pronates the lower leg.
Muscle hypertrophy is not similar for all muscles. The variation ranges from 8 to 51% in the forequarters and from 9 to 34% in the hindquarters.

Double muscling in cattle is associated with higher blockiness
A beef carcass is made up of over a hundred different muscles. These muscles have different properties which affect processing characteristics and consumer acceptability.
Double muscling is associated with positive traits of economic value, such as increased muscle mass, higher meat yield, a higher proportion of expensive cuts of meat, and higher meat leanness and tenderness. However, double muscling can also cause increased susceptibility to dystocia, respiratory disease, lameness, muscle degeneration, and heat stress. Additionally, double-muscled cattle have smaller organ size and experience additional pressure on the skeleton.

Research is being conducted to profile the physical and chemical characteristics of beef muscles
The beef carcass is made up of over a hundred different muscles. These muscles have different properties, which affect processing characteristics and consumer acceptability. There has been a continued trend to separate muscles, based on these characteristics, to better market them. Today, the majority of cuts found in the retail meat counter are boneless, therefore providing the need for knowledge of the musculature of the beef animal.
The four muscles within the stifle joint compartment include vastus lateralis, vastus medias, vastus intermedius, and the straight muscle. These muscles extend the stifle joint and flex the hip joint. The popliteal muscle flexes the stifle joint and pronates the lower leg.

Frequently asked questions
There are four muscles in a cow's leg: vastus lateralis, vastus medias, vastus intermedius and the straight muscle.
There are over a hundred muscles in a cow's carcass.
No, they do not. Research has shown that muscle hypertrophy varies from 8 to 51% in the forequarters and from 9 to 34% in the hindquarters. Additionally, the pre-slaughter growth rate of beef cattle can affect meat tenderness.
