ABSTRACT - The objective of this work was to investigate whether puberty and parturition alter the antral follicle count (AFC) in female Nelore (Bos indicus) beef cattle. Two experiments were carried out to compare AFC between the prepubertal and pubertal periods and between the prepubertal and postpartum periods. AFC and follicle concentrations did not differ between the prepubertal and pubertal periods. However, the ovarian area increased after puberty. In addition, AFC and the ovarian area were greater in the postpartum than in the prepubertal period. Therefore, AFC is not affected by the puberty of Nelore heifers, but increases significantly when the prepubertal heifers become cows.
RESUMO - O objetivo deste trabalho foi avaliar se a puberdade e o parto alteram a contagem de folículos antrais (CFA) em fêmeas Nelore (Bos indicus) de corte. Foram realizados dois experimentos para comparar a CFA entre os períodos pré-púbere e púbere e entre os períodos pré-púbere e pós-parto. A CFA e a concentração folicular não diferiram entre os períodos pré-púbere e púbere. Entretanto, a área ovariana foi maior após a puberdade. Além disso, a CFA e a área do ovário foram maiores no período pós-parto quando comparado ao pré-púbere. Portanto, a CFA não é afetada pela puberdade de novilhas Nelore, mas aumenta significativamente quando as novilhas prépúberes se tornam vacas. |

The Amazon basin is the world's largest rainforest and the most biologically diverse place on Earth. Despite the critical importance of this region, Amazon forests continue inexorably to be degraded and deforested for various reasons, mainly a consequence of agricultural expansion. The development of novel policy strategies that provide balanced solutions, associating economic growth with environmental protection, is still challenging, largely because the perspective of those most affected - local stakeholders - is often ignored. Participatory fuzzy cognitive mapping (FCM) was implemented to examine stakeholder perceptions towards the sustainable development of two agricultural-forest frontier areas in the Bolivian and Brazilian Amazon. A series of development scenarios were explored and applied to stakeholder-derived FCM, with climate change also analysed. Stakeholders in both regions perceived landscapes of socio-economic impoverishment and environmental degradation driven by governmental and institutional deficiencies. Under such abject conditions, governance and well-integrated social and technological strategies offered socio-economic development, environmental conservation, and resilience to climatic changes. The results suggest there are benefits of a new type of thinking for development strategies in the Amazon basin and that continued application of traditional development policies reduces the resilience of the Amazon to climate change, whilst limiting socio-economic development and environmental conservation.
