Nesta pesquisa avaliou-se o efeito do colesterol sobre o sêmen de garanhões da raça Nordestina sobre a qualidade espermática. Vinte ejaculados de dois garanhões foram diluídos com BotuSemen e colesterol carreado pela ciclodextrina (CCC) adicionado no sêmen: controle, 0,75mg de CCC e 1,0mg de CCC/120x106 sptz/mL, e incubado a 26°C/15min. O sêmen foi diluído 1:5 (v/v) com diluente Lactose-gema de ovo e resfriado a 5°C/2h, envasado em palhetas de 0,5mL, e acondicionado sob vapor de nitrogênio líquido, e depois imersos. As amostras foram descongeladas (37 °C/30s) e avaliadas. As variáveis foram avaliadas com ANOVA e teste de Tukey (P<0,05). A motilidade total e progressiva foi maior (P<0,05) no sêmen tratado com CCC comparado as amostras do grupo controle, e CCC promoveu maior percentual (P<0,05) de motilidade total e progressiva durante as 3 horas de incubação. A percentagem de espermatozoides com viabilidade e integridade foi maior (P<0,05) no sêmen tratado com CCC (81,47 e 86,07%) comparado ao controle (72,12 e 70,19%). O número de espermatozoides reativos ao teste hiposmótico foi maior (P<0,05) nas amostras de sêmen tratadas com CCC comparado ao controle. Adição de colesterol no sêmen de garanhões Nordestino melhora a qualidade espermática apos a criopreservação. |

Brazil's rural landscapes are critically important for global climate, economic development, and food security. The integration of crop and animal production within a single farm (ICLS) is a promising agricultural innovation to improve livelihood and environmental outcomes in these landscapes. Here we synthesize recent work examining the drivers of ICLS adoption in Brazil, as well as the economic, environmental and social tradeoffs associated with these systems, with a focus on the Legal Amazon region. Our research finds that ICLS are largely an economic and environmental win-win compared to existing extensive cattle management practices and other pasture intensification alternatives. Adopters of ICLS are well aware of the economic benefits of these systems - improved income, greater adaptability, and reduced environmental impact, while non-adopters are less aware of the benefits. High upfront costs, greater managerial intensity, existing lifestyle preferences, as well as limited access to markets, credit, and technical information remain key barriers to diffusion. Given these diverse barriers to adoption, a comprehensive mix of positive and negative financial incentives is needed to both push and pull further intensification innovations from their current niche to widespread adoption. On the push side, there is a need to vastly increase the number of demonstration farms and training seminars on successful ICLS practices. On the pull side, agricultural policies need to be re-oriented to accommodate the longer-term benefits of ICLS, including longer payback periods on loans and positive incentives for intensification via stringent restrictions on deforestation for additional land clearing and payments for environmental services. Finally, joint efforts by the private sector and government are needed to promote cattle value chain upgrading, including improved infrastructure and machinery access to enable pasture renovation and crop production in more remote regions, and better transparency about cattle origin and management practices to signal the sustainability of the sector.
