Abstract
ABSTRACT:
The present study was carried on clinical cases related to affections of udder and
teats referred to TVCSC, NTR College of Veterinary Science, Gannavaram. The cases
were randomly selected following thcrough clinical examination .Ultrasonography was
conducted by restraining the buffaloes in trevis to record normal and pathological
condition of udder and teat disorders in buffaloes by using a 7.5MHz linear array
transducer. Among the udder lesions highest incidence of udder oedema was recorded
followed by mammitis, atrophy and fibrosis, abscess, haematoma and varicosity with an
overall incidence of 4.2 % udder lesions . The incidence of teat lesions was 2.5 1% with
a highest incidence of intralurninal obstructions followed by polythelia, oligothelia, teat
lacerations /fistulas and intralurninal foreign bodies, allergic mastitis and papillomas
/neoplasms , fused teats and pox lesions.
Four methods viz., direct contact method , gel application. water bath method
and stand off method were compared for ultrasonography of udder and teats . In direct
contact method the application of the transducer on to teat or udder surface was easy but
the shape of the teat was altered. Gel application method improved the contact of the
transducer to record ultrasonographic images. The udder and teats were dipped in a water
bath made of polyethelene bag/condom filled with water for ultrasonographic
examination. Gel filled condom was used as standoff pad to examine the udder and teat
ultrasonographically. Among all the methods water bath and gel application methods
showed better visualization of udder and teat with almost all anatomical structures.
The normal sonographic appearance of gland parenchyma , gland sinus, teat wall,
teat sinus, teat canal and rosette of Furstenberg were recorded. Udder lesions like
marnmitis, oedema. varicosity, haematoma, abscess, atrophy and fibrosis were recorded
ultrasonographically. They appeared with different echogenecity. Sonographic diagnosis
of teat lesions includes thelitis, intraluminal obstructions, intraluminal foreign bodies,
trauma / fistula, teat stenosis, atresia and fibrosis. Ultrasonographic measurement of teat
diameter, teat wall thickness, teat cistern diameter and teat canal length was done in
lactating and non lactating buffaloes to know the functional status of the teat. To
conclude ultrasonography could be used as non invasive diagnostic tool to identifii the
lesions of udder and teats in buffaloes.
