Ultrasonography of teat in surti goats

The present study was conducted on twenty clinically healthy adult surti goats weighing 15 to 20 kg, free from clinical and sub-clinical mastitis or teat injuries. Teats were examined by ultrasonography (USG) with 7.5 -10 MHz linear transducer using direct contact and water bath techniques. Ultrasonographically, parenchyma, lobes, major duct, gland cistern, teat cistern, teat/streak canal were visualized. Measurement of the structures i.e. teat end width (TEW), teat canal length (TCL), teat cistern width (TCW) and teat wall thickness (TWT) were also recorded using in build caliper in USG machine. The mean ± SE measurements of TEW, TCL, TCW and TWT in lactating goats were 1.34± 0.07, 1.74± 0.13, 0.38± 0.04 and 0.55± 0.02 cms, respectively, whereas the corresponding mean ± SE values in non lactating goats were 1.02± 0.03, 1.06± 0.06, 0.24± 0.01 and 0.46± 0.02 cms.
