Abstract. The aim of the study was to compare ultrasound measurements of the gland cistern in goats obtained by various methods. The tests were conducted on goats of the Polish White Improved breed. Four ultrasound devices were used in the experiment, which were equipped with 4 different types of probes. The most similar measurements, rp from .729 to .927, were obtained with the use of a SonoVet2000 with a linear probe with the frequency of 5 MHz, applied to the middle part of the udder base, penetrating the opposite udder half and a Hitachi EUB 405+ with a 5.0 MHz convex probe applied to the middle part of the base of the diagnosed udder half, directing the emission surface of the probe towards the teat.
