DIAS, Juliano C. et al. Sexual behaviour in young Guzerat bulls in libido test in pen and pasture conditions. []. , 43, 1, pp.248-264.   29--2020. ISSN 0871-018X.  https://doi.org/10.19084/rca.17569.

Twenty four Guzerat bulls from 24 to 34 months olds, andrologically evaluated as normal were submitted to a libido test, to study sexual behaviour in pen and pasture conditions. It was observed, in a general way, low reply of the animals to the tests, once that half of them were classified with average or high libido. Lower variation in the punctuation between the observation times was verified, in the pen test with score 3.0 in five minutes and 3.3 in 15 minutes of evaluation (p>0.05). It was recorded, in a general way, favorable associations and of high magnitude among the events, suggesting that bulls that showed more events in the libido test are those with higher change to carry through matings.
