• Study on foot lesions with special reference to
  diagnosis and treatment of footrot in sheep

2

• Objectives of the study

3

• A total of 6614 sheep which were clinically
  screened, 859 had different types of foot lesions
  with an overall prevalence of 12.98.

17
Age wise prevalence

• Incidences of various foot lesions noted at a
  higher rate in the lambs of 7-12 M age group
  (16.28), followed by 14.99 percent in 1-2 years
  age

18
Breed wise

• Deccani breed (17.55) was reported to be highly
  susceptible when compared to the Nellore Jodepi
  (12.18).

19

• Gender has no influence over the prevalence of
  foot lesions

20

• The ratio of incidence of foot lesions was more
  in forelimbs (72.64) than in hind limbs
  (27.35).

Season wise prevalence

• FOOTROT

23
Footrot

• A total of 258 sheep were suspected for footrot.
  clinical material were collected from suspected
  foot lesion

24
Swabs processed and screened for the
confirmation of Footrot infection by PCR
Technique.
25
Out of the 258 foot swabs, 72 samples were found
positive for D.nodosus using 16S rRNA gene
26
PREVALENCE-GENDER WISE

• Incidence of footrot was more in females (26.41)
  than in males (20.37).

27
AGE WISE

• Higher incidence was noted in age group of 1-2
  years both in Nellore Jodepi (32.65) and Deccani
  breed (31.82).

28
ANATOMICAL DISPOSITION

• Analysis of footrot data based on anatomical
  disposition revealed higher prevalence in
  forelimbs (65.27) than in hind limbs (34.71).

• SEASON WISE
• footrot - seasonal disease
• noticed mostly during North-East monsoon period
  (20.34) and winter (32.74) in Andhrapradesh.

31

• Month wise-
• More number of footrot cases were recorded from
  October to February months, during which the
  rainfall was high (gt400mm) with more spells of
  continuous rain for 3-5 days.

32

• clinical sign
• pyrexia,
• anorexia/in appetence,

33
hyperemia and swelling in Interdigital space
34
Accumulation of grey pasty cum in the
interdigital space
35
Dullness and emaciation
36

37
Lameness
38
loss of wool and rough coat
39

• REDUCED BREEDING PERFORMANCE both in ewes and
  rams.

40

• Therapy
• Twenty footrot positive sheep were divided
  randomly into two groups (Group-I and Group-II).

41

• Treatment regimen included antibiotics
  (enrofloxacin _at_1ml/10 kg body wt I/M for Group-I
• and
• Procaine G Pencillin _at_ 6666 IU per kg.body wt I/M
  for Group-II) NSAID (Meloxicam _at_ 0.2 mg/kg body
  wt., I/M

42
antiseptic footbath (10 zinc sulphate solution)
for both the groups.
43
(Group-I).

• Clinical recovery is faster in enrofloxacin
  treated sheep, as lameness subsided and lesion
  score reduced to zero and all other clinical
  parameters resumed to normalcy by 5th day post
  treatment except the body and coat condition,
  compared to sheep treated with Procaine G
  Penicillin

45
(Group-II).

• The sheep in this group took 7-10 days for
  complete recovery in terms of absence of lameness
  by obtaining zero lesion score. The clinical
  recovery in terms of demeanor and other vital
  parameters was less fast in Procaine G Penicillin
  treated sheep as compared to enrofloxacin treated
  sheep
