ABSTRACT.- This study investigated two outbreaks of spontaneous poisoning by Baccharis coridifolia (Asteraceae) in early-weaned beef calves in Tacuarembó, Uruguay. A total of 34 affected calves showed signs of salivation, anorexia, apathy, marked dehydration, and diarrhea. Deaths occurred 36-72 h after consumption and mortality varied from 37.5% to 43.3% for outbreak 1 and outbreak 2, respectively. The main pathological findings include diffuse severe necrosis of the prestomachs and lymphoid tissues. Ultrastructurally, epithelial cells of the rumen showed swelling, lysis of the organelles, degradation of intercellular attachments, and degradation of the nuclear chromatin. Using LC-MS with diagnostic fragmentation filtering, 56 macrocyclic trichothecenes including glycosyl and malonyl conjugates were identified. The total concentration of macrocyclic trichothecenes, including conjugates, was estimated to be 1.2 ± 0.1 mg/g plant material. This is the first report of these malonyl-glucose conjugates from Baccharis coridifolia. © 2023 by the authors. |

The aim of this study was to evaluate the effect of pre slaughter lairage time on cattle welfare. Thirty Hereford steers were randomly grouped in two treatments according to lairage time in the abbatoir pens: 12 hours (Treatment 1, n = 15) and 3 hours (Treatment 2, n = 15). The behavioral records were obtained through the identification of body posture (standing) and frequency of negative behaviors (mounts and fighting). Blood samples were taken from all animals searching for basal values in Creatine phosphokinase (CPK) as a welfare indicator and also its changes at different pre slaughter periods. Muscle samples were extracted from Longissimus thoracis et lumborum (LM) muscles 45 minutes post mortem, to determine glycogen concentration. Data was analyzed by SAS software applying GLM and GLIMMIX procedures. All animals were standing during the first 3 hours and negative behavior showed the highest frequency during the first 3 hours in both treatments. Animals in Treatment 2 showed an increase in CPK concentration after lairage. Additionally, Treatment 2 (3 hours) had lower values of muscle glycogen concentration. In conclusion, is possible to infer that the animals that remained in pens (Tretament 1) could rest and recover after wards, being this not possible for animals in the shorter lairage group. |
