The effects of inclusion levels of a phytogenic feed additive(PFA), characterized by menthol anethol and eugenol, on broiler growth performance, nutrient digestibility, biochemical biomarkers and total antioxidant capacity(TAC) of plasma and meat, as well as on the relative expression of selected cytokines,were studied in a 42-d experiment. A total of 225 one-day-old male Cobb broiler chickens were assigned into 3 treatments, with 5 replicates of 15 chickens each. Chickens were fed maize-soybean meal basal diets following a 3 phase(i.e., starter, grower and finisher) feeding program. Depending on PFA inclusion level, treatments were: no PFA(PFA-0), PFA at 100 mg/kg(PFA-100) and PFA at 150 mg/kg(PFA-150).Feed and water were available ad libitum. Feed conversion ratio(FCR) during finisher phase was improved quadratically(P < 0.05) with increasing PFA level. Overall, increasing PFA level increased body weight gain(BWG) in a linear(P < 0.05) and quadratic(P < 0.05) manner with treatments PFA-100 and PFA-150 being greater(P < 0.05) compared with PFA-0. Total tract apparent digestibility of dry matter increased linearly(P < 0.05) and quadratically(P < 0.05) with increasing PFA level. The apparent metabolizable energy corrected for nitrogen(AMEn) also increased linearly(P < 0.05). Increasing PFA level resulted in a linear(P < 0.05) increase in blood plasma TAC. Expression of pro-inflammatory cytokine interleukin-18(IL-18) was reduced linearly(P < 0.05) in spleen with increasing PFA level. In conclusion, PFA inclusion at 100 mg/kg diet positively influenced performance, whereas PFA inclusion at150 mg/kg resulted in a stronger improvement in AMEn and plasma TAC. Finally, PFA inclusion resulted in a pattern of reduced pro-inflammatory biomarker IL-18 at spleen. Overall, this study provides evidence for the beneficial role of PFA as a natural growth and health promoter in broiler chickens that needs to be further confirmed in field studies.

植物提取物具有非常广泛的生物活性,包括抗菌、抗炎症和抗真菌。自从欧盟及其他国家禁用抗生素生长促进剂(AGPs)后,对其替代物的寻找就已经拉开了帷幕,并且很多研究也瞄向AGPs替代物的寻找。

More than Target 6.3： A Systems Approach to Rethinking Sustainable Development Goals in a Resource-Scarce World

引用

Engineering 2016年第4期2卷 481-489页

作者： Qiong Zhang christine Prouty Julie B. Zimmerman James R. Mihelcic University of South Florida Tampa EL 33620 USA Yale University New Haven CT06520 USA

The 2030 Agenda for Sustainable Development outlines 17 individual Sustainable Development Goals （SDGs） that guide the needs of practice for many professional disciplines around the world, including engineering, research, policy, and development. The SDGs represent commitments to reduce poverty, hunger, ill health, gender inequality, environmental degradation, and lack of access to clean water and sanitation. If a typical reductionist approach is employed to address and optimize individual goals, it may lead to a failure in technological, policy, or managerial development interventions through unin- tended consequences in other goals. This study uses a systems approach to understand the fundamental dynamics between the SDGs in order to identify potential synergies and antagonisms. A conceptual system model was constructed to illustrate the causal relationships between SDGs, examine system structures using generic system archetypes, and identify leverage points to effectively influence intentional and minimize unintentional changes in the system. The structure of interactions among the SDGs reflects three archetypes of system behavior： Reinforcing Growth, Limits to Growth, and Growth and Underinvestment. The leverage points identified from the conceptual model are gender equality, sustainable management of water and sanitation, alternative resources, sustainable livelihood standards, and global partnerships. Such a conceptual system analysis of SDGs can enhance the likelihood that the development community will broaden its understanding of the potential synergistic benefits of their projects on resource management, environmental sustainability, and climate change. By linking the interactions and feedbacks of those projects with economic gains, women＇s empowerment, and educational equality, stakeholders can recognize holistic improvements that can be made to the quality of life of many of the world＇s poor.
