ABSTRACT:
Weaning calves at a young age can generate great stress, but it is widely practiced in the industry despite that. So, to what extend weaning in early ages is more stressful than at later ones, in terms of the amount of stress, is currently unknown. Thus, we studied the behavioural and physiological impacts in beef calves at three ages at weaning (30, 75, and 180 days) and the consequences of the calf?s sex. Thirty-six calves were weaned and distributed in hyper-early (W30), early (W75), and conventional (W180) weaning groups, which are weaning
ages that occur in practice. Behavioural activities and physiological parameters were measured on days 0, 1, 2, and 7 after weaning. Canonical component analysis (CCA) and analysis of variance (ANOVA) were used to evaluate behavioural and physiological parameters. The variables analysed were influenced by the treatment, day of evaluation and interaction between treatment × day, and without effect for sex. The younger the calf, the greater the intensity of responses to the weaning stress. In this sense, the behavioural results (percentages of
observations ± SEM) demonstrate that on D0, W30 calves emitted more extreme vocalization (61 %) compared to W75 (15 %) and W180 (0%) (P < 0.001); on D1, W30 and W75 calves expressed more extreme sounds (61 % and 50 %, respectively) than W180 (21 %) (P = 0.028). Similarly, W30 and W75 calves showed a higher number of cross-sucking (P = 0.006). On D0, differences in the frequency of walking (P < 0.001) were observed, once calves of W30 (45.5 ± 6.21 %) and W75 (39.9 ± 6.03 %) spent more time in this activity than W180 ones (17.3 ± 3.80 %). Also, more visiting the feeder without eating feed events were verified (P = 0.014) on D0 (11.5 ± 2.59 %) and D1 (6.2 ± 1.65 %) for W30 when compared to W180 calves (2.6 ± 1.73 % and 0.0 ± 0.00 %, respectively). In physiological terms, a higher respiratory rate (P = 0.043) on D0 was identified for W30 calves (66.3 ± 2.90 breaths/min) than for W75 (57.8 ± 2.30 breaths/min) or W180 (47.3 ± 2.02 breaths/min). Cortisol concentrations were higher (P = 0.019) on D0 for W30 animals (15.6 ± 3.40 ng/mL) than for W180 ones (9.7 ± 1.90 ng/mL). The peak of cortisol occurred on D1 for W30 and D2 for W75 and W180. Therefore, behavioural and physiological changes at young ages indicate greater calf suffering, which may have negative consequences on a productive life. MenosABSTRACT:

The rice crop and associated ecosystems constitute a rich mosaic of habitats that preserve a rich biological diversity. Spiders are an abundant and successful group of natural predators that are considered efficient in the biocontrol of the major insect pests in agroecosystems. Spider diversity in different stages of the rice crop growth from eastern Uruguay was analysed. Field study was developed on six rice farms with rotation system with pasture, installed during intercropping stage as cover crop. Six rice crops distributed in three locations were sampled with pitfall and entomological vaccum suction machine. Sixteen families, representing six guilds, were collected. Lycosidae, Linyphiidae, Anyphaenidae and Tetragnathidae were the most abundant families (26%, 25%, 20% and 12%, respectively) and comprised more than 80% of total abundance. Other hunters (29%), sheet web weavers (25%) and ground hunters (24%) were the most abundant guilds. Species composition along different crop stages was significantly different according to the ANOSIM test. The results showed higher spider abundance and diversity along the crop and intercrop stages. This study represents the first contribution to the knowledge of spider diversity associated with rice agroecosystem in the country. |
