Abstract:This work studies the acute contact toxicity of oxalic acid (OA) on a honeybee polyhybrid subspecies (Apis mellifera),
which is the dominant biotype in southwestern zone of Uruguay (SWZU) and the country?s most important honey-producing
region. We determined the mean lethal dose (LD50), as well as the no observed effect level (NOEL) and the lowest observed
effect level (LOEL) values. We also estimated the total number of honeybees per hive in the test area. The aim was to assess
the relationship between the maximum OA dose used in Uruguay (3.1 g OA per hive) and the toxicological parameters of
honeybees from SWZU. The current dose of 3.1 g OA per hive corresponds to 132.8 µg OA per honeybee since determined
NOEL is 400 µg OA per honeybee; our results indicate that the current dose could be increased to 9.3 g OA per hive. The
results also highlight some differences between the LD50 value in SWZU honeybees (548.95 µg OA per honeybee) and
some published LD50 values for other honeybee subspecies. |

Abstract. The objectives of this study was to evaluate three types of grain silage sorghum with different levels of tannins and roughage management on animal performance, meat and carcass traits of steers finished in feedlot. The experiment was conducted at the INIA, Colonia, Uruguay. A total of 48 Angus x Hereford, with 20-22 months of age and with initial weight of 355 ± 58kg were used. The animals were distributed in blocks by initial weight in a 3 x 2 factorial arrangement. For weigh, weight gain and meat and carcass traits the model included the effect of sorghum grain, roughage management, the interaction between sorghum grain and roughage management, the block and the effect of period. The means were compared with the Tukey-Kramer test (p< 0.05). The daily weight gain was higher when roughage was supplied separated from the concentrated in the high tannins treatments. The effect of interaction between sorghum grain and roughage management was not significant for carcass and meat traits. The roughage management may influence weight gain, depending on the type of sorghum used. Except for marbling content. |
