Disease Process in Animals foot rot in cattle b.stev

THIS is due to SUSCEPTIBILTY from : Trauma from the environment Excessive moisture to the skin Irritants (sprays/ foilage/ clothing) Bites (insect/ predator) The dimensions of the animal Exposure of the feet to contaminants MICROBES grow infection (Hirsh .D. C, MacLachlan .N. J & Walker .R.L, 2004)

THIS is due to SUSCEPTIBILTY from :

Trauma from the environment

Excessive moisture to the skin

Irritants (sprays/ foilage/ clothing)

Bites (insect/ predator)

The dimensions of the animal

Exposure of the feet to contaminants

what is FOOT ROT ? ACUTE inflammation: skin & tissue > inter-digital cleft LESION often accompanies this CATTLE in muddy areas are especially prone: dairy/ beef

usually: 1 - 2 cattle at a time: though, OUT-BREAKS to certain situations occur due to conditions& work of the animal/s Infection is from microbes: Fusobacterium necrophorum Bacteroides melaninogenicus CAUSES: muddy/ poorly drained pens OR pastures (University of Florida, 2008)

Infection is from microbes:

Fusobacterium necrophorum

Bacteroides melaninogenicus

WHAT HAPPENS? WET ground , faeces , mud softens the skin - microbes then enter through small abrasions ie: a stone bruise/ thorn/ wood/ frozen faeces

occurs : HIND feet most often PROMPT diagnosis saves time/ money & the loss of production from the animal SIGNS: raises the foot - reluctance to move loss of appetite, weight/ impaired gait (University of Florida, 2008)

animal/s are cleaned for inspection – the VET needs to ensure it is foot rot LARGE HERDS: feed additive, a control measure ALSO: - chlortetracycline - oxytetracycline ANTIMICROBIAL THERAPY ie: antibiotic given 3 - 5 days TREATMENT: Vetinerary Inspection is required (Cattle Today Inc, 2008)

WITH severe foot rot : removal of a CLAW may by necessary RECOVERY : animal has a single claw NEGLECT to the animal would cause a significant cost in treatment & loss of economic production from the animal
