| 摘 要： | 目的]生物垫床养牛成功的关键在于垫料厚度和菌种的选择使用。垫料一般以稻壳、木糠为主,市场上菌种质量参差不齐,且价格昂贵,导致效果千差万别。本研究主要对垫料厚度和菌种进行筛选试验,以获得能够适用于广西地区牛用生物垫床的最适厚度和最优菌种,为生物垫床的推广应用提供数据支撑。方法]研究以木糠作为垫料,A、B2个菌种开展研究,分设3个不同厚度(5 cm,10 cm,15 cm)6个组和无垫料2个组。结果]结果表明,第1组和第4组(5cm垫料厚度)腐坏面积大,差异显著(P<0.0.5)。第3组和第6组(15 cm垫料厚度)板结的垫料多,造成垫料的浪费,差异显著(P<0.0.5)。第2组和第5组之间垫床的影响差异不显著(P>0.0.5),生物垫料组(第2组和第5组)的氨气浓度与无(粪)垫料组(第7组和第8组)差异显著(P<0.0.5)。结论]第2组的生物垫料和A菌种成本低、腐坏面积小,10 cm的垫料厚度是比较理想的垫料厚度,适合广西牛用生物垫床的饲养要求。

| Abstract: | Objective] The key to the success of cattle raising with biological mattresses is the thickness of the matting material and the selection and application of bacteria species. Generally, rice husk is the main filler, and the quality of bacteria in the market is uneven, and the price is expensive, resulting in a wide range of effects. In this study, the thickness of bedding material and strain were selected to obtain the optimum thickness and strain of cattle bio-mattresses in Guangxi, and to provide data support for the popularization and application of bio-mattresses. Method] The paper used wood bran as bedding material, A and B strains of the microorganisms were studied and divided into 3 groups(5 cm, 10 cm, 15 cm) with different thicknesses and 2 control groups without bedding material. Results] The results showed that there was a significant difference between the first group and the fourth group(5 cm cushion thickness) in the area of deterioration(P< 0.05) and the deterioration region is large. The 15 cm thickness(3 and 6 groups) of the bedding material was caked which resulted in the waste of the bedding material and the difference was significant(P<0.05). There was no significant difference between the 2 and 5 groups(P>0.05), and the NH3 concentration in the biological bedding groups(2 and 5 groups) was significantly different from that in the non-bedding groups(7 and 8 groups)(P<0.0.5). Conclusion] The biological fermentation bedding and strain A in group 2 have low cost, small rotten area, and the 10 cm bedding thickness is the better ideal bedding thickness, which is suitable for cattle fermentation bedding in Guangxi. |
