Selected technological solutions can impact health status of animals. The aim of this case study was to determine the effect of different housing systems on disease prevalence and the productive lifespan of dairy cows. In total, 480 cows kept indoors on one farm in four buildings using four different housing systems (a free-stall barn with a slatted floor; a free-stall barn with a self-cleaning floor; an open-pack barn with deep litter; a tie-stall barn with shallow litter) were analyzed. The data from 6 years, based on veterinary reports, were processed statistically in Statistica 13.00. The study demonstrated that the average productive lifespan was longer (p ≤ 0.01), by up to more than 8 months, in the system with deep litter, which was also characterized by the lowest disease prevalence (p ≤ 0.01), especially foot and some reproductive disorders. This trend was maintained in each year of the study period (2015–2020). In the tie-stall barn, the prevalence of mastitis was reduced, but the risk of lameness, retained placenta, parturient paresis and displaced abomasum was higher in this system (p ≤ 0.01). Overall morbidity was highest in the free-stall barns. Lower morbidity was associated with an increase in productive herd life.

住房系统对奶牛群疾病流行和生产寿命的影响——一个案例研究

选定的技术解决方案会影响动物的健康状况。本案例研究的目的是确定不同畜舍系统对疾病流行和奶牛生产寿命的影响。总共有 480 头奶牛在一个农场的四栋建筑物中使用四种不同的饲养系统（一个带板条地板的散养牛舍；一个带自清洁地板的散养牛舍；一个带有深垫料的开放式牛舍；分析了一个带有浅垫料的平摊谷仓）。基于兽医报告的 6 年数据在 Statistica 13.00 中进行了统计处理。研究表明，在垫料较深的系统中，平均生产寿命更长（p ≤ 0.01），最长可达 8 个月以上，这也是疾病患病率最低的特点（p≤ 0.01)，尤其是足部和一些生殖障碍。这一趋势在研究期间的每一年（2015-2020 年）都保持不变。在固定畜舍中，乳腺炎的患病率降低，但在该系统中出现跛足、胎盘滞留、分娩麻痹和真胃移位的风险较高（p ≤ 0.01）。散养谷仓的总体发病率最高。较低的发病率与生产性牛群寿命的增加有关。
