Incidence of feedlot lameness varies by feedlot from .03% to 2.3% of cattle inventory on a health data base that includes
5,540,000 cattle in feedlots that vary in capacity from 5000 to 80,000 head. The average lameness incidence is .51%. Lameness
case fatality rates can approach 15% and railer rates meet or exceed case fatality rates. Losses due to lameness are understated
on most health summaries because significant numbers of lame cattle are left in pens to recover without treatment. The majority
of lameness cases are infections or injuries following trauma associated with transport, receiving, and arrival processing.
Proper interactions between caregivers and cattle can reduce lameness risk.
Lameness prevention responsibilities begin at the unloading chute. Cattle relocation is a stress. The first impression cattle
have of their new home is of critical importance. Unloading and weighing cattle is an opportunity for handlers to convince
cattle to trust caregivers enough to be willing to walk by them with confidence. Provide stable footing at the receiving area
by covering concrete with wood shavings or rubber mats. Avoid sharp turns at the bottom of the chute to prevent cattle from
falling or bumping shoulders and hips.
Develop specific strategies for taking new cattle to home pens. Ask cattle to file by handlers and if possible send cattle
beyond their home pen so they stop, turn, and volunteer to come back by a handler to enter their new home. Always have fresh
hay and ration in the bunk and clean water present prior to sending cattle home. Follow cattle into the pen and place cattle
at the bunk. Encourage pen riders to train cattle to travel straight in single file fashion. This investment in time will
facilitate processing and will encourage cattle to express arrival health and lameness. Document lameness present on arrival
and communicate arrival issues to order buyers and sale barns.
Teach handlers how to remove cattle from home pens. Cattle that volunteer to leave their home pen are more willing to file
through processing facilities. Handlers should use no vocalization and be willing to form a straight line in a T to the gate
to signal cattle to leave the pen. Develop an understanding of cattle flow within processing teams. Never bring cattle to
a crowding tub or Bud Box if the alley is full. Bring small drafts of cattle that can go immediately to the chute. Teach handlers
to use gentle negative pressure to convince cattle to volunteer to enter facilities to reduce the use of no-backs. Monitor
alleys and chutes for sharp surfaces that could cause foot lacerations. Cover concrete surfaces with wood shavings to prevent
toe abrasions and sole abscesses. Cattle that are confident of their footing require a fraction of the pressure required to
move cattle that are on slick surfaces. Teach handlers to work from the front of cattle to encourage cattle flow into the
chute. Adjust the bottom of chutes to allow cattle flow and prevent hoof damage. Teach chute operators appropriate use of
hydraulic pressure. Provide rubber mats in front of the chute and expect cattle to walk out of the chute.
Processing Facility Design
Revise contemporary facility design. Fences covered with sheet metal and solid alleys increase cattle anxiety, interfere with
their peripheral vision, and increase lameness risk. Cattle need to see what is pressuring them and will volunteer to enter
facilities if they can see where they are expected to go. It should be obvious to cattle that an exit exists. Cattle prefer
to go back to where they came from and are willing to go around handlers. Investigate the use of the Bud Box facility design
and train handlers to send cattle through a straight, open, adjustable alley leading to the chute. Lameness risk is reduced
when cattle are willing to walk to the chute, stop to be processed, and walk out of the facility.
Buller activity is a significant source of feedlot lameness, reduces performance, and requires additional labor. Attention
to detail during arrival acclimation, processing, and pen riding reduces buller incidence. Arrival bunk management is a critical
part of buller control. Train pen riders to identify pens with buller potential and insist that riders use exercise and pen
riding methods that reduce confinement anxiety. Watch for initiators of buller activity and move those cattle temporarily
into the drovers alley to increase their desire to eat and drink.
