6. Definition

7. Foot Rot

8. Gram –negative bacteria is a non forming anaerobe

9. Predisposing Causes

10. Predisposing Causes
❖Footrot tends to be seasonal, with the highest incidence
occurring during the wet seasons.
❖Cuts, bruises, puncture wounds, or severe abrasions of
the foot due to sharp rocks, sticks, or frozen mud/ice will
damage the skin in the interdigital space and predispose an
animal to foot rot by allowing bacteria to invade and
multiply within the tissue.

and an overgrown
outer hoof wall.

19. Diagnosis

20. Diagnosis
❖Footrot is typically diagnosed by the distinctive lesions
and odor.
❖Any interdigital fissures and cracks with a characteristic
odor scchouldbe treated as foot rot.
❖Bacterial culture can be done, but is rarely necessary.

21. Differential Diagnosis

22. Differential Diagnosis in sheep
Contagious eczema(ORF): Scabesaround the mouth and cornet

23. Foot and mouth diseases (FMD)
❖: It is a infectious highly contagious, vesicular disease of
cloven footed animals, caused by virus, characterized by
fever, salivation and vesicular eruptions in the oral cavity
and on the feet or udder and teats.

24. Bluetongue (BT)
❖: It is an infectious non contagious insect born disease of
❖sheep primarily and cattle occasionally, caused by virus,
characterized by fever, ulcerative stomatitis, rhinitis,
enteritis and lameness due to inflammation of coronary
band and sensitive laminae of the foot.
❖The disease is slow in spread and seasonal in occurrence.

26. Main Line of Treatment

27. Main Line of Treatment
❖1-Local antiseptic and antibiotic
❖2-Systemic antibiotic
❖3-Non steroidal anti-inflammatory
❖4-Vitamin AD3E.

28. 1-Local Antibiotic &Antiseptic
❖The interdigital tissue should be cleaned, debrided, and
❖disinfected.
❖Formalin 10% or copper sulphat20%.
❖Use of an antibiotic spray.

29. 2-Systemic Antibiotic
❖Penicillin and oxytetracycline are effective antibiotics
if started early in the disease process and given at the
❖recommended dosage.
❖Sulfonamides (either intravenously or as a bolus) work
well too.

30. Antibiotic in sheep

31. جلاعلل ةتشور
1-Systemic antibiotic (Pencilline/Streptomycin):
R / Pentomycine2 ml/50 Kg B.wtI/M for 5-7 days
2-Steroidal Anti-inflammatory
R/ Dexamethasone 5 ml I/V.
3-Supportive therapy (Vitamins)
R/ (AD3E+C) 15 ml/I/M.
4-Foot path:
All necrotic tissue must be removed and the area must be
treated with foot bath (zinc sulphate 10%).

33. Foot Pathing

34. Zinc Supplementation
❖Providing a balanced diet that includes supplementing
cattle nutrition programs with zinc .
❖Zinc methionine at a minimum recommended level of 360
mg zinc per head per day helps increase the animal’s
resilience to clinical disease by maintaining good skin
integrity and improving immune function.

35. Foot Pathing
Zinc

10%
Copper
Sulphate
Formalin 3%

36. 1-Foot Pathing(Zinc Sulphate )
Zinc Sulphate at 10% is the most
common treatment option.

37. كنزلا تاتيربك لولحم ريضحت ةقيرط
❖A 10 % solution is made by mixing 1 kg zinc sulphate
powder to 9 liters of water.
❖The depth of the solution should be 5 cm or greater

38. 2-Foot Pathing(Copper Sulphate)
Solution of copper salts used for foot
bathing every 2 weeks for 15 minutes.
A 10 liter container is diluted in 100
liters of water.
This product is effective and gives a
longer period of protection between
applications/bathing

39. 3-Formalin3%
Solution of formalin 3%used for foot
bathing .
This product is not safe

40. ❖The recommended minimum contact
time is 5-10 minutes.
❖Prolonged soaking of up to 1 hour is
recommended for higher value animals.

41. Important Notes
❖•Foot bathing alone will not eradicate foo trot and should
only be used as part of a whole-farm control and eradication
program as planned with your local Animal Health Adviser
or veterinarian.

42. Important Notes
❖Sheep may be stood in a foot bath for up to an hour.
❖This is very time consuming but may be worthwhile for
high value animals (e.g. rams).

43. Important Notes
❖•Sheep should not be foot bathed for 6 weeks prior to the
first summer inspection as it may reduce the chance of
detecting infected sheep.

44. Foot Pathing

45. Foot bathing is most
effective if the sheep have
clean, hard standing
available afterwards. All
equipment must be clean
before use.

46. Trimming of the claws
is recommended to
remove excess tissue
that provides a place
for the bacteria to
thrive.

47. Prevention

48. Prevention
❖Do not buy lame animals and thoroughly inspect the feet of
all animals before purchase.
❖All new purchases and all animals that have left the farm
and returned should be quarantined for 30 days.
❖Provide good drainage in pastures and paddocks and keep
the barn clean and dry.
❖Also, practice regular hoof trimming and good hoof care
and management.

49. Prevention
❖Feet should be trimmed and soaked in foot baths of zinc
sulfate or copper sulfate.
❖Regular foot trimming (at least one to two times per year)
reduces the number of crevices where bacteria can live,
removes infected hoof, and exposes the organism to air and
various medications.
❖Always disinfect trimming instruments between animals to
prevent spreading foot rot.

50. Summery

51. Contagious foot-rot symptoms include:
❖Redness
