Concrete is the most commonly used alley flooring in confined dairy herds because of its qualities of construction and ease of cleaning. Nevertheless, the hardness, abrasiveness, and slipperiness of concrete floors have adverse effects on animal well-being and health, and yielding rubber flooring is becoming popular as a way of improving the flooring conditions on walkways. The aim of this study was to investigate preferences of dairy cows for rubber compared with concrete flooring under the conditions of a commercial dairy farm. The study was conducted in an organic dairy herd with free-stall housing. Floor preference was tested on groups of standing cows in a 120-m2 holding pen before milking, and 1 yr later on a 12- × 3-m walkway. The holding pen and the walkway were divided lengthwise into 2 identical sections. Two types of solid rubber mats (soft and extra soft) were tested against solid concrete in the holding pen. Slatted and solid rubber mats were tested against slatted concrete in the walkway. Each floor type was tested over 4 d on the left side and 4 d on the right side of the holding pen and the walkway, respectively. Concrete flooring on both sides of the sections was tested as a control before the testing of different section materials. All observations of the distribution of cows in the sections were made from video recordings captured in association with the afternoon milking. The number of cows on each section was recorded approximately every 7 min in the holding pen, and continuously on the walkway. A significantly higher proportion of cows stood on the side with the soft and extra soft rubber mats (65.1 ± 2.7 and 69.3 ± 2.6%, respectively, mean ± SEM) compared with the control distribution when only the solid concrete was available (50.9 ± 3.9%). A significantly higher proportion of nonlame cows walked exclusively on the side with the slatted (64.5 ± 5.4%, d 4) or solid rubber mats (68.2 ± 5.1%, d 4) compared with controls (28.9 ± 4.3%). Lame cows within a group of walking cows did not show a higher preference for soft flooring as distinct as nonlame cows (52.7 ± 6.9 and 59.4 ± 6.2% for the solid and slatted rubber mats, respectively, at d 4 vs. 40.3 ± 6.2% for control), presumably because of competition with other, higher ranked cows. It was concluded that the majority of cows preferred to walk and stand on soft rubber rather than on concrete flooring.  相似文献

暖体假人软质模拟皮肤的研究及其应用   总被引:2,自引:2,他引:0  
为改善目前现有硬材料暖体假人与真实人体表面弹性的差异性,提高特殊功能服装测试的精度,对暖体假人上使用的一种软质模拟皮肤进行研究。选择6种高分子弹性体,分别是热硫化硅胶、天然乳胶、医用硅胶、聚苯乙烯系弹性体TPR、聚烯烃系弹性体EVA和热塑性聚氨酯TPU,在拉伸、压缩、热性能等多项实验的基础上,研究高分子弹性体的综合性能,并通过模糊数学的模糊决策理论选出综合性能最优的暖体假人模拟皮肤材料。通过在稳定环境条件和变化环境条件2种状态下的暖体假人实验,证明这种模拟皮肤材料在提高暖体假人控制精度、稳定性和环境耐受性方面发挥了良好的效果。  相似文献

The objective was to test if there was an association between free-stall base softness and milk yield, incidence of clinical mastitis (CM), teat lesions, and removal of cows. In a questionnaire sent to 1,923 dairy farms presumed to be using free-stall housing, farmers were asked for information regarding housing and stall base; for example, the year of installation and the product name or brand of their mats or mattresses. This information was merged with data for milk yield, CM, teat lesions, and removal of cows extracted from the Norwegian Dairy Herd Recording System for the years after installation of mats or mattresses. After exclusion of invalid contributions, the data set consisted of 29,326 lactations for milk yield distributed over 363 free-stalled herds in Norway. The farms were stratified into 5 categories according to the softness of the stall surface measured as millimeter impact of a sphere with a diameter of 120 mm at 2-kN load: 1 = concrete, softness of 0 mm; 2 = rubber, softness of 1 to 8 mm; 3 = soft mats, softness of 9 to 16 mm; 4 = multilayer mats, softness of 17 to 24 mm; and 5 = mattresses, softness over 24 mm. Lactation curves were estimated as modified Wood's lactation curves using test-day data and mixed models with repeated measurements, adjusting for days in milk, parity, and softness of free-stall flooring. Herds on concrete free-stall bases yielded 6,727 ± 146 kg of milk from 5 to 305 days in milk. In comparison, herds showed a decrease of 0.3% on rubber, an increase of 2.4% on soft mats, an increase of 4.5% on multilayer mats, and an increase of 3.9% on mattresses. Compared with concrete, the hazard ratio (HR) of CM was less on rubber, multilayer mats, and mattresses [HR = 0.89 (0.79-0.99), 0.85 (0.73-0.996), and 0.80 (0.73-0.88), respectively]. Compared with concrete, the HR of teat lesions was less on rubber, soft mats, multilayer mats, and mattresses [HR = 0.41 (0.26-0.65), 0.33 (0.24-0.44), 0.12 (0.04-0.38), and 0.47 (0.33-0.67), respectively]. The HR of removal of cows was less on mattresses compared with concrete, rubber, soft mats, and multilayer mats, with HR = 0.90 (0.84-0.97), 0.88 (0.80-0.97), 0.86 (0.80-0.93), and 0.85 (0.76-0.95), respectively. A soft free-stall base contributed significantly to increased milk yield and fewer incidences of CM, teat lesions, and removal of cows.  相似文献

A soft rumen cannula for sheep was made with two kinds of silicone rubber and a polyethylene plug. The design of molds is simple and the materials can easily be obtained. The elasticity of the cylindrical part of the cannula controlled leakage of rumen contents to a minimum, and the moderate hardness of the flange prevented loss of contents from the rumen. The cannula could be used repeatedly and functioned well for over 4 yr. The cannula was easily pushed into the rumen, and the collection of whole digesta was accomplished easily by hand. A small amount of sampling with pipette could be achieved through the punched opening without removing the inner polyethylene plug.  相似文献

The production of soft cheese is considered in detail and illustrated by examples including varieties such as cottage cheese, carrick and camembert. It is shown that a diverse range of products can be manufactured by careful manipulation of a relatively small number of processing conditions. The methods are equally applicable to sheep or goat milk. As a result, soft cheese production offers scope for the farmhouse cheesemaker wishing to add value to milk.  相似文献
