Feral pigs (S. scrofa) were introduced to the Pantanal region around 200 years ago and the population appears to be in expansion. Its eradication is considered to be impossible. The population of feral pigs in the Pantanal wetlands is currently estimated at one million. Two scientific excursions were organized. The first was conducted during the dry season, when 21 feral pigs were captured and the second was during the wet season, when 23 feral pigs were captured. Ticks were collected and the oviposition and hatching process were studied to confirm the biological success of each tick species. Three tick species were found to be feeding on feral pigs: Amblyomma cajennense, A. parvum, and Ornithodoros rostratus. During the dry season, 178 adult A. cajennense were collected, contrasting with 127 A. cajennense specimens in the wet season. This suggests that the seasonality of these ticks in the Brazilian Pantanal wetlands could be different from other regions. The results indicate that A. parvum and A. cajennense are biologically successful parasites in relation to feral pigs. A. cajennense appears to have adapted to this tick-host relationship, as well as the areas where feral pigs are abundant, and could play a role in the amplification of this tick population. |

The objective was to evaluate reproductive characteristics of crossbred Girolando (Gyr x Holstein) bulls from two breed compositions and correlate these results with infrared thermography data. Evaluations were performed considering sperm motility, vigor and morphology; scrotal circumference; body morphology and temperament. Infrared thermography was performed to determine surface temperatures of ocular and scrotal areas. Thermoregulation capacity was assessed by differences between air and rectal temperatures, air and maximum temperatures in ocular and scrotal areas, and dorsal and ventral lines of the scrotum. Data analysis was performed using a linear mixed model (breed composition as fixed effect and year of evaluation as random effect). Spearman correlation coefficient was used to associate thermography and reproductive data. Girolando 3/4 Holstein bulls had higher (P ≤ 0.001) scrotal circumference and higher average body morphology and temperament, whereas 5/8 Holstein bulls had a higher (P < 0.001) percentage of major-type and total sperm defects. Girolando 3/4 Holstein bulls had scrotal temperatures 0.8 °C higher (P < 0.001) and 5/8 Holstein bulls had 9.8% and 10.6% higher differences on ?rectal ? scrotal area? and ?ocular area ? scrotal area? temperatures, respectively. Ocular area temperatures had negative correlations (P ≤ 0.1) with sperm motility and vigor, and positive correlations (P < 0.001) with minor-type and total sperm defects. Ventral line scrotal temperatures had positive correlations (P < 0.001) with minor-type and total sperm defects. Girolando 3/4 Holstein bulls were found to be superior to 5/8 Holstein bulls for reproductive characteristics. Under non-stressing climatic conditions, semen characteristics of Girolando bulls were more influenced by breed composition than by the capacity for scrotal thermoregulation. Correlations between semen quality and scrotal temperatures can aid in the identification of bulls for breeding, particularly when a large number of animals are in the tests.
