Bottom Line: These two techniques were also compared with semen analysis.The findings of each technique were compared.There was agreement in classification of fertile bulls using all three techniques, suggesting that the combined use of these techniques enhances routine breeding soundness examination.

ABSTRACT
The aim of this study was to evaluate the usefulness of trans-scrotal ultrasonography and testicular fine needle aspiration cytology in assessing bulls for breeding suitability. These two techniques were also compared with semen analysis. Bulls presented for breeding soundness evaluation were assessed using all three techniques. The findings of each technique were compared. There was agreement in classification of fertile bulls using all three techniques, suggesting that the combined use of these techniques enhances routine breeding soundness examination. Use of the three techniques also enhances detailed investigation of suspected sub-fertile bulls while accurately identifying testicular cause(s) of sire sub-fertility.

Normal testicular ultrasonograph of a three-year-old Angus bull showing homogenous granular parenchyma. The ultrasonograph was obtained using a B-mode real time portable ultrasound scanner (SonoAce 600V: Edinburgh) with a 7.5 MHz linear array transducer.

Figure 2: Normal testicular ultrasonograph of a three-year-old Angus bull showing homogenous granular parenchyma. The ultrasonograph was obtained using a B-mode real time portable ultrasound scanner (SonoAce 600V: Edinburgh) with a 7.5 MHz linear array transducer.

Mentions: Twenty-five bulls had no lesions detectable by transscrotal ultrasonography (Figure 2). The remaining seven bulls had abnormal testicular parenchyma and, as such, were considered unsuitable for breeding. The testicular ultrasonographic abnormalities identified were: fluid accumulations (n = 3); testicular abscess (n = 1); orchitis (n = 1); and testicular fibrosis (n = 2). Testicular abseccesation and fibrosis were also identifiable on testicular palpation. Table 1 shows the classification of the 32 bulls using the three techniques as either suitable (pass) or unsuitable (fail) for breeding.
