摘　　要：[目的]为了探讨广西高温高湿环境下生物垫床牛舍适合的养殖密度,给广大养殖户提供数据支撑。[方法]试验采用不同的生物菌种对不同的生物垫床的厚度进行筛选,得出最佳的生物垫床厚度。按照15 kg/m2,20 kg/m2,25 kg/m2,30 kg/m2,35 kg/m2饲养牛体重所占面积对相同面积的垫床饲养密度进行试验。[结果]研究结果表明,以10 cm生物垫床的厚度,养殖能吸纳牛粪尿,有效地减少粪尿的排放,20 kg/m2密度时后备牛对生物发酵垫床适应性好,与传统饲养方式相比,牛蹄病发生率降低了5.55%。[结论]适宜的生物垫床厚度和适宜的养殖密度不但节省了兽药的使用成本,而且还降低了劳动力成本,效果较好。[Objective]In order to explore the suitable breeding density of the biological bedding cowshed in the high temperature and humidity environment of Guangxi.The purpose is to provide scientific support for the vast number of farmers.[Method]Different biological strains were used to screen the different thickness of the biological bedding,and the best thickness of the biological bedding was obtained.According to 15 kg/m2,20 kg/m2,25 kg/m2,30 kg/m2,35 kg/m2 feeding area of cattle weight,the feeding density of the same area of the bedding was tested.[Result]The results showed that with the thickness of 10 cm biological bedding,the bedding could effectively absorb and reduce cattle dung and urine.When the density was 20 kg/m2,the reserve cattle had good adaptability to biological fermentation bedding,and the incidence of cattle hoof disease was reduced by 5.55%compared with the traditional feeding mode.[Conclusion]The appropriate thickness of biological bedding and the appropriate density of feeding not only save the cost of veterinary medicine,but also reduce the labor cost,with good effect.
