Resumo: O monitoramento do peso e escore de condição corporal dos rebanhos auxilia na busca de resultados favoráveis na eficiência reprodutiva e produtiva em ovinos. Em razão disso, no presente estudo, procurou-se investigar o peso e escore de condição corporal de ovelhas deslanadas criadas em pastagem nativa suplementadas durante a estação de monta e terço final de gestação. Aos 21 dias antes da estação de monta as matrizes foram divididas em três grupos experimentais para o fornecimento do flushing, por um período de 42 dias. No terço final de gestação as ovelhas foram suplementadas com concentrado na quantidade de 400g/cabeça/dia. O peso das ovelhas ao parto não foi influenciado pelo tratamento ou grupo genético (P>0,05). O tipo de nascimento influenciou (P<0,05) o peso das ovelhas ao parto, as ovelhas com partos triplos apresentaram maior peso vivo ao parto que aquelas de parto simples, sendo que as ovelhas que pariram dois cordeiros não diferiram dos dois outros grupos. O escore de condição corporal após o parto foi influenciado (P<0,05) pelo tratamento, grupo genético e tipo de nascimento. [Weight and body condition score at calving of ewes raised on native pasture supplemented during the breeding season and the final third of gestation]. Abstract: The monitoring of weight and body condition score of herds assists in search of favorable results in productive and reproductive performance in sheep. For this reason, in the present study, we sought to investigate the weight and body condition score of ewes raised on native pasture supplemented during the breeding season and the final third of gestation. At 21 days before the breeding season arrays were divided into three groups for the supply of flushing for a period of 42 days. In the final third of gestation, ewes were supplemented with concentrate on the amount of 400g/head/day. The ewe weight at birth was not affected by treatment or genetic group (P>0,05). The type of birth had a significant (P <0,05) birth weight of sheep, the sheep with triple births had higher body weight at birth than those of simple birth, with the two lambs lambed ewes which did not differ from the other two groups . The body condition score after calving was influenced (P <0,05) by treatment, genetic group and type of birth.

Forest recovery following management interventions is important to maintain ecosystem functioning and the provision of ecosystem services. It remains, however, largely unclear how above-ground biomass (AGB) recovery of species-rich tropical forests is affected by disturbance intensity and post-disturbance (remaining) tree-community attributes, following logging and thinning interventions. We investigated whether annual AGB increment (ΔAGB) decreases with management-related disturbance intensity (disturbance hypothesis), and increases with the diversity (niche-complementarity hypothesis) and the community-weighted mean (CWM) of acquisitive traits of dominant species (biomass-ratio hypothesis) in the remaining tree community. We analysed data from a long-term forest-management experiment in the Brazilian Amazon over two recovery periods: post-logging (1983?1989) and post-thinning (1995?2012). We computed the ΔAGB of surviving trees, recruit trees and of the total tree community. Disturbance intensity was quantified as basal area reduction and basal area remaining. Remaining diversity (taxonomic, functional and structural) and CWM of five functional traits linked to biomass productivity (specific leaf area, leaf nitrogen and phosphorous concentration, leaf toughness and wood density) were calculated for the post-intervention inventories. Predictors were related to response variables using multiple linear regressions and structural equation modelling. We found support for the disturbance hypothesis in both recovery periods. AGB increment of survivors and of the total tree community increased with basal area remaining, indicating the importance of remaining growing stock for biomass recovery. Conversely, AGB increment of recruit trees increased with basal area reduction because changes in forest structure increased resource availability for young trees. We did not find consistent support for the niche-complementarity and biomass-ratio hypotheses, possibly because of a high redundancy in these extremely species-rich forests Synthesis and applications. The intensity of disturbance through management, expressed as basal area reduction and basal area remaining, was consistently more important for explaining forest biomass recovery following harvesting and thinning than remaining diversity or trait composition. This points to the importance of controlling logging and thinning intensity in forests of the eastern Amazon. Given the high intervention intensities applied in this experiment, it is likely that low to moderate harvesting intensities permitted by the current legislation for the Brazilian Amazon (30 m³/ha) will not impair biomass recovery in these forests MenosForest recovery following management interventions is important to maintain ecosystem functioning and the provision of ecosystem services.
