Abstract
The present study was undertaken to study prevalence, diagnosis and
treatment of mastitis in lactating goats. Clinical examination of a total of 220 graded
Jamunapari lactating goats, belonged to private owners in and around Durg district of
Chhattisgarh state revealed 3.18% prevalence of clinical mastitis. For detection of sub
clinical mastitis milk samples were subjected to various diagnostic tests viz. BTB,
MWST, MCMT and SCC. The prevalence of SCM in goats were 26.77%, 30.05%,
41.32% and 52.59% by BTB, MWST, MCMT and SCC respectively. On udder half
basis, prevalence were 20.65% by BTB, 23.24% by MWST, 30.75% by MCMT and
46.00% by somatic cell count. Prevalence rate was higher in right udder half
(28.24%) than the left udder half (6.16%). The distribution of udder halves by SCC in
SCM in respect to left half, right half and both halves were 3.58%, 10.72% and
42.86% respectively. The higher prevalence of SCM was recorded during 2nd
lactation and in 4 years age. The present study revealed that the percentage of
severity of ‘++’reaction by all 4 indirect diagnostic tests was highest. Among the four
diagnostic tests, MCMT was found most sensitive, as there was 78.57% correlation
with SCC, followed by MWST (57.14%) and BTB (50.89%). It was also found that
there was significant difference between affected and healthy goats in respect to total
leukocyte count in the blood. The present study did not reveal any significant
correlation between SCC in milk and TLC and DLC in the blood.
A total of 50 isolates were obtained from 24 udder halves positive to SCM.
Among the various microorganisms isolated, the Staphylococcus spp. occupied prime
position with 32(64%) isolates. Other microbes in descending order of their
frequency were Streptococcus spp.6 (12%), Mixed infection 8(16%),
Corynebacterium spp. 3(6%), Bacillus spp. 1(2%). Out of 50 isolates tested for their
antibiogram amoxycillin showed sensitivity to maximum number of isolates 12
(24%), followed by ciprofloxacin 11(22%), gentamicin 9 (18%), ceftriaxone +
tazobactum 9(18%) and chloramphenicol 9(18%).
In the present study, efficacy of tri-sodium citrate and ceftriaxone
+tazobactum alone and in combination was assessed in the treatment of subclinical
mastitis in goats based on MCMT, MSCC, TLC and DLC. Treatment with sodium
citrate alone caused 37.75% reduction in sub clinical mastitis in goats whereas
antibiotic treatment caused 19 % reduction in infection. On the other hand, goats
which received combination of tri-sodium citrate and ceftriaxone +tazobactum
showed 56.25% reduction in infection. So, it could be inferred that the combined
therapy of antibiotic and sodium citrate was more effective than either sodium citrate
or antibiotic in the control of sub clinical mastitis.
