Lameness is leg or foot pain that affects how cattle move. There are many different kinds of lameness, with many different causes, such as genetics, environment, injury, nutrition, and a variety of infections. Lameness can negatively affect both animal welfare and growth performance, because animals may be reluctant to eat or drink if standing or walking is painful.

Importance to the Beef Industry

Lame feedlot cattle grow more slowly than cattle that are not lame (1.75 lbs/day vs 2.95 lbs/day)1. Similarly, steers diagnosed with footrot during the finishing period need up to two weeks longer to reach slaughter weight2. A lower rate of gain can be costly in terms of welfare, labour, pen space and feed.

Many animals will recover with appropriate treatment. Chronic cases may be salvaged, provided all pharmaceutical withdrawal requirements have been met and the animal can be transported without additional suffering. Humane euthanasia on the farm is recommended when animal welfare is severely compromised and not expected to improve.

Incidence

Lameness is rare in healthy cattle. A recent study assessing 3,243 receiving feedlot cattle between 400 to 700 lbs in one Kansas feed yard reported the incidence of lameness to be 1.6% at the time of pre-processing and 2.5% up to 40 days after processing3. A 2007-08 survey of 50,000 beef cattle transported in Ontario identified 79 lame cattle4, and a 2008 survey of over 290,866 beef cattle transported in Western Canada found 37 lame cattle5.

Lameness is more common in unhealthy cattle. A survey of five large feedlots in Kansas and Oklahoma found lameness to account for 16% of all recorded feedlot health problems6. Data collected at three Alberta feedlots reported the prevalence of lameness in the chronic pens varied between 32.8-52.8%, with an overall average of 37%1.

Lameness is also more common in older cattle. A 2008 survey of 18,949 auction mart cattle in the Western U.S. found that 15% of beef bulls and cows, 26% of dairy bulls and 45% of dairy cows were lame6. Western Canada’s transport survey also reported that lameness was considerably more common in market cows than in fed cattle, feeders or calves5.

Treatment

Accurate diagnosis is important for successful treatment and prevention of future cases. Producers should not assume that lame cattle have footrot without close observation, to avoid unnecessary administration of antibiotics.

"Most people look at a lame cow and assume it’s foot rot. However, foot rot is a very specific disorder. If it’s foot rot, it will get better with antibiotic treatment. If a producer calls and says, ‘Doc, I’ve got a cow with a bad case of foot rot that I’ve been treating for a week,’ then I know it’s not foot rot. It’s either something else, or it’s been neglected too long before treatment was begun and it has gone into the joint. Recognizing foot rot is highly important, so I teach people some of the clues.”

“When an animal gets foot rot, the key thing is swelling above the hoof. The swelling is symmetrical and affects both digits, forcing the claws apart. If you look closely at the foot, you will see a grey-green slimy mass sticking out from the skin between the claws. If you give that animal antibiotics the foot will get better. Anything else that’s causing lameness needs to be looked at by a veterinarian.”

Causes

Four common causes of lameness include:

  1. Genetics (e.g. bad conformation, corns, corkscrew claw, puffed hock)
  2. Nutrition (e.g. laminitis, sole ulcerations, double sole, bruised sole, heel erosion, white line disease, toe ulcers)
  3. Infection (e.g. footrot, infection of the coffin joint, interdigital dermatitis, and infectious arthritis)
  4. Physical injury (e.g. broken leg, frostbitten feet)
Lameness may have multiple causes. For example, when hyperexcitable cattle (which may have a genetic component) scramble on hard flooring, they may damage the sole of the feet (injury), allowing bacteria to enter and colonize the foot (infection). This is one theory to explain P3 necrosis (also known as 'toe necrosis').

Each of these causes is associated with specific risk factors. For example, trauma or wet conditions that may affect skin integrity causes lameness directly and provides an avenue for bacteria to enter and colonize a wound.

Producers should not assume that lame cattle have footrot without close observation, to avoid unnecessary administration of antibiotics.

Risk Factors

Common risk factors associated with an increased incidence of lameness include:

  • Facility design flaws that can cause hoof and leg injuries
  • Sharp edges or protruding objects (wire, metal, rocks, ice or frozen manure) that can contribute to physical injuries
  • Aggressive or improper animal handling practices can increase the occurrence of slipping, falling and physical injury8,9
  • Buller steer syndrome can increase foot and leg injuries9,10
  • Extremely wet (muddy) pen conditions11
  • Slick surfaces that cause animals to slip (i.e. more lameness on concrete or slatted floors versus strawed flooring12)
  • Cattle having an excitable temperament are more likely to damage the soles of their feet or injure their legs/feet
  • Mycoplasma bovis the bacterial agent associated with infectious arthritis and bovine respiratory disease (BRD)13
  • Nutrition related to the feeding of high grain diets, erratic consumption of grain, and improper feed processing leading to laminitis and/or founder.

Prevention and Control

Management practices that may help to reduce lameness include:

  • Pen landscaping (mounds), proper drainage, and cleaning to reduce excessive mud
  • Removing sharp objects from the pen such as rocks
  • Appropriate precautions to reduce the risk of BRD (such as low-stress weaning, preconditioning, vaccination and other prophylactic measures)
  • Handling practices and well-designed and maintained facilities that reduce potential for animal injury
  • Veterinary consultation regarding potential use of a Fusobacterium necrophorum vaccine for  footrot14
  • Careful management of step-up rations and high-grain diets to reduce the risk of acute acidosis.
