为了分析拴系奶牛的肢体疼痛，我们比较了三种奶牛地板垫材料（牧场垫（R）[PM]、KKM橡胶垫（R）[RM]和木片[WC]）与土壤地面，考虑了施加到荷斯坦奶牛前膝的压力。对3头荷斯坦干奶牛（791.3 +/- 44.6 kg，3.8 +/- 1.1岁）进行了试验，这些奶牛停泊在信州大学农学部高山田野科学教育和研究中心。使用市售的压力测量表比较了由四种不同的地板垫材料施加到奶牛前膝的压力。施加到试验母牛前膝的持续压力为7.2 +/- 1。在对照、RM、PM和WC中分别为29.3 +/- 5.1、17.0 +/- 1.4和27.7 +/- 2.5 MPa，显示出显著低于对照的值（P < 0.05）。持续压力在PM组显著低于其他处理组（P < 0.05）。RM比PM便宜41.7%。奶牛前膝关节所受的压力在PM上低于RM和WC。PM比RM成本更高，但PM的持续压力要低得多。
To analyze limb pain in tethered dairy cows, we compared three cow floor mat materials (pasture mat (R) [PM], KKM rubber mat (R) [RM], and woodchip [WC]) with soil ground considering the pressure applied to the anterior knee of Holstein cows. Three Holstein dry cows (791.3 +/- 44.6 kg, 3.8 +/- 1.1 years old) moored at the Education and Research Center of Alpine Field Science of the Faculty of Agriculture, Shinshu University, were tested. Pressure applied to the anterior knee of the cow by four different floor mat materials was compared using a commercially available pressure measurement sheet. The sustained pressures applied to the anterior knee of the test cow were 7.2 +/- 1. 5, 29.3 +/- 5.1, 17.0 +/- 1.4, and 27.7 +/- 2.5 MPa in the control, RM, PM, and WC, respectively, showing significant lower values (P < 0.05) than in the control. Sustained pressure was significantly lower in the PM than in the other treatments (P < 0.05). The RM was 41.7% cheaper than the PM. The pressure applied to the anterior knee of cow is lower on PM than on RM and WC. PM was more costly than RM but the sustained pressure was much lower on PM.
