This study aimed to compare the biomass obtained via the biogasification of straw with the classic bedding material, wheat straw. It was divided into two stages. In the first stage, a laboratory evaluation of the bedding materials was carried out, taking into account dry matter, pH, and water absorption. In the laboratory tests, the bedding obtained after the biogasification of straw (Verbio) showed better sorptive properties, with a value of 439.86% (wheat straw's value was 294.10%), and its pH value was higher than that of wheat straw. In the second stage of the experiment, field tests were carried out on a production farm, wherein the bedding was evaluated for bedding hygiene, animal hygiene, insulation properties, animal productivity, and microbiological properties. A microbiological assessment was also performed. Regarding cleanliness and production parameters and thermographic insulation properties, the two types of bedding did not show statistically significant differences. In terms of microbiological parameters, a higher number of all examined types of bacteria and fungi was observed in the Verbio bedding compared with straw, but these differences were not statistically significant, except in the case of total coliform. The results indicate that straw obtained after gasification is a suitable bedding material, with parameters similar to those of wheat straw.
本研究旨在比较通过秸秆沼气化获得的生物质与传统垫料小麦秸秆。该研究分为两个阶段。在第一阶段，对垫料进行了实验室评估，考虑了干物质、pH值和吸水性。在实验室测试中，秸秆沼气化后获得的垫料（Verbio）表现出更好的吸附性能，其值为439.86%（小麦秸秆的值为294.10%），且其pH值高于小麦秸秆。在实验的第二阶段，在一个生产农场进行了田间试验，对垫料的垫料卫生、动物卫生、保温性能、动物生产力和微生物特性进行了评估。还进行了微生物评估。在清洁度、生产参数和热成像保温性能方面，两种垫料没有显示出统计学上的显著差异。在微生物参数方面，与秸秆相比，Verbio垫料中所有检测类型的细菌和真菌数量都更高，但除了总大肠菌群外，这些差异没有统计学意义。结果表明，气化后获得的秸秆是一种合适的垫料，其参数与小麦秸秆相似。
