The hygienic practices on farms should reduce pathogenic microorganisms while simultaneously not harming the animals themselves; they must also not degrade the products' quality. We assessed the effect of covering feed tables with paint containing silver nanoparticles (AgNPs) and the periodic spraying of effective microorganisms (EM) on production indicators and basic chemical composition, mineral content and fatty acid profiles in the bodies of snails. The animals were divided into four groups: (1) control, (2) with feed tables covered with AgNPs paint, (3) with EM spray applied and (4) with both factors-AgNP paint and EM spray. The highest increase in Ag, Zn, Fe and Ca retention, and the remodelling of the fatty acid profile in the carcasses of snails was found to be in the group of animals in contact with the feed tables covered with AgNP paint. In the group of animals exposed to the action of EM, an increased retention of Fe, Cu, P, Mg and Zn was found.
养殖场的卫生措施应减少病原微生物,同时不伤害动物本身;这些措施还不能降低产品质量。我们评估了用含银纳米颗粒(AgNPs)的涂料覆盖饲料槽以及定期喷洒有效微生物(EM)对蜗牛生产指标、基本化学成分、矿物质含量和体内脂肪酸谱的影响。将动物分为四组:(1)对照组,(2)饲料槽覆盖有AgNPs涂料组,(3)喷洒EM组,(4)同时具备AgNP涂料和EM喷洒两个因素组。结果发现,接触覆盖有AgNP涂料饲料槽的动物组,其体内银、锌、铁和钙的保留量增加最多,且胴体脂肪酸谱发生重塑。在暴露于EM作用的动物组中,铁、铜、磷、镁和锌的保留量增加。
