Effect of Flooring and/or Flooring Surfaces
نویسنده
چکیده
A study published in 1996 by the National Animal Health Monitoring System (NAHMS) indicated that 15% of cows culled from dairy herds in the United States were culled as a “direct effect” of lameness. This sounds reasonable until one considers that the “indirect effects” of lameness on production and reproduction are estimated to account for an additional 49.1% of culling in US herds. Although these data are now 10 years old, it is doubtful that the impact of lameness on culling has improved much since that time. The obvious question is why?

متن کاملStudy on the Friction of Bored Cylindrical Rubber Protrusions Sliding on Ceramic
The present work aims at reducing the friction of rubber soles sliding on ceramic floorings. Fitting bored cylindrical protrusions with different diameters on rubber soles was proposed. Experiments were carried out to evaluate the performance of the proposed protrusions in increasing friction coefficient at dry and contaminated floorings. It was found that, at dry sliding, friction coefficient ...
متن کاملGround Reaction Forces and Friction during Stroke Gait: the Flooring Surface Effect
The aim of this study is to investigate the effect of flooring surfaces in the ground reaction forces and foot/floor friction during stroke gait. The participant was oriented to walk, in its own preferred speed, over two force plates on the following surfaces: HOV, carpet and HTV. The results of this study showed no differences between the hemiparetic and the control group when de GRF and COF w...
متن کاملUse of water spray and extended drying time to lower bacterial numbers on soiled flooring from broiler transport coops.
Broiler transport coops soiled with Campylobacter-positive feces have been shown to facilitate cross-contamination of broilers. Washing and sanitizing coop surfaces do not always effectively eliminate bacteria. The objective of this study was to examine drying as a means of lowering bacterial numbers on transport coop flooring. Small squares (5 x 5 cm) of fiberglass flooring from transport coop...
