Resumo
The amount of beef cattle finishing in feedlot or semi-feedlot is higher in the off season, and
when the animals are closed together the incidence of buller-steer syndrome increases. The
purpose of the study was to evaluate the effect of the homeopathic medicine with Pulsatilla
nigricans, Urtica urens, Estrogen and Hypothalamus on homosexual, social and basic
behaviors and performance of Nellore bulls finished in feedlot system. 100 crossbred bulls
Nellore with 25 months age an average was selected. Behavioral results were submitted to
variance analysis (ANOVA) in random design blocks with repeated measure at the time,
evaluating treatment effects and times of day, and the blocks were four repetitions of the four
evaluated weeks. As for performance, the animals were distributed in completely randomized
design in two treatments: T1 control treatment, without homeopathic medicine and T2:
homeopathic treatment. Observations of basic, social and sexual behavior were made by a
trained observer who recorded the group behavior based in etograma. Four observations were
made in weekend, starting on Saturday afternoon and ending Sunday morning, with 2 hours
duration per observation, at 1:30 pm, 5:30 pm, 5:30 and 9:00, and so a total of 8 hours per
weekend, totaling 192 observational records during the trial period. The homeopathic
medicine Bos Libido/Sodomia was mixed with kibble, 40 g/day/animal. Also, the performance
was evaluated. Results showed no interaction (p < 0.05) between the use of homeopathic
medicine and the day period for any observed behaviors. Animals of T2 spent 46.5% of the
time lying down while the animals of T1 only 36.7%. Animals of T1 spent a lot of time with
the display while the T2 saved energy. Sexual behavior variables of SOD, FUGMT and RF
showed difference between treatments, and the occurrence average was 24.7 and 6.1 to
SOD; 7.0 and 1.8 to FUGMT; and 13.1 and 4.8 to RF in T1 and T2, respectively. The
homeopathic medicine reduced the buller-steer syndrome and improved agonistic and basic
behavior. However, there was no significant difference in performance.
