摘要

硒是动物必需的微量元素。在芬兰，由于土壤中的硒含量极低，传统农业中使用补饲硒和富硒常量营养素肥料。本研究的目的是用酵母硒(SY)完全或部分(50/50)替代矿物质-维生素混合物中的亚硒酸钠(SS)，提高有机牛奶中的硒浓度。饲养试验于2008年春季在芬兰东部15个经认证的有机奶牛场进行。交叉试验设计为3个处理(SS处理、SY处理和SS/SY处理)，3个试验期(每个试验期28 d)， 3个农场组(处理顺序不同)。用相同量(0.2 mg Se kg-1饲料干物质)的SY代替SS，有机奶中Se浓度增加一倍以上，两者混合后Se浓度略有降低。综上所述，为了提高有机奶中硒的含量，提高奶牛、犊牛和消费者的硒供应，需要补饲SY。

Increasing selenium concentration in Finnish organic milk using participatory action approach

Selenium (Se) is an essential trace element for animals. In Finland, Se supplementary feeding and Se-enriched macronutrient fertilisers are used in conventional farming because the Se availability from soil is extremely low. The objective of this study was to improve Se concentration in organic milk by replacing sodium selenite (SS) in mineral-vitamin mixture with selenium yeast (SY) either completely or partly (50/50). The feeding experiment was conducted on 15 certified organic dairy farms in Eastern Finland during spring 2008. The cross-over design consisted of three treatments (SS treatment, SY treatment, and SS/SY treatment), three experimental periods (28 days each), and three farm groups (different order of treatments). Replacing SS with the same amount (0.2 mg Se kg-1 feed dry matter) of SY more than doubled Se concentration in organic milk and their mixture resulted in slightly lower Se concentrations. In conclusion, SY supplementary feeding is needed to improve Se concentration in organic milk and Se supply to cows, their calves, and consumers.

期刊介绍： Agricultural and Food Science (AFSci) publishes original research reports on agriculture and food research related to primary production and which have a northern dimension. The fields within the scope of the journal include agricultural economics, agricultural engineering, animal science, environmental science, horticulture, plant and soil science and primary production-related food science. Papers covering both basic and applied research are welcome. AFSci is published by the Scientific Agricultural Society of Finland. AFSci, former The Journal of the Scientific Agricultural Society of Finland, has been published regularly since 1928. Alongside the printed version, online publishing began in 2000. Since the year 2010 Agricultural and Food Science has only been available online as an Open Access journal, provided to the user free of charge. Full texts are available online from 1945 on.
