Most free-stall housing systems in the Netherlands are equipped with slatted or solid concrete floors with manure scrapers. A slipping incident occurs when the required coefficient of friction (RCOF) exceeds the coefficient of friction (COF) at the c

Development of Claw Traits and Claw Lesions in Dairy Cows kept on different floor systems

Autor: J.H.M. Metz, W.G.P. Schouten, E.N. Noordhuizen-Stassen, Klaas Frankena, J.G.C.J. Somers

Several claw shape measurements, horn hardness, and horn growth and wear were recorded monthly at 12 dairy farms to investigate the effect of floor type and changes in these traits over time. Herds were either housed on a slatted floor (SL), solid co

The pressure distribution under the bovine claw while walking was measured to test the hypotheses that the vertical ground reaction force is unevenly distributed and makes some (regions of the) claws more prone to injuries due to overloading than oth

Claw health was examined in an observational study on Dutch dairy farms with either a slatted floor (SL), slatted floor with manure scraper (SL-SCR), solid concrete floor (SCF), a straw yard (SY), or a zero-grazing feeding system (ZG). Hooves of cows

The distribution pattern of pressure over the bovine claw was investigated to test the hypothesis that the ground reaction force is unevenly distributed and makes some regions of the claw more prone to overloading and injury than others. In eight rec

The objective of this study was to determine the relationship between body-condition score and postpartum reproductive efficiency in dairy cattle. Data on body-condition score, reproduction, diseases, and production from 1404 lactations of 639 cows,

Undesirable side effects of selection for high production efficiency in farm animals: a review

Livestock Production Science 56 (1998) 1

Genetic selection has increased production levels of livestock species considerably. However, apart from a favourable increase in production, animals in a population that have been selected for high production efficiency seem to be more at risk for b
