“…The application of the results obtained for hard floors had some limitations, because the sensor surface represented a very smooth floor, whereas the actual roughness of the floor affected contact pressure and contact area (De Belie and Rombout, 2003). In addition, a slatted floor may cause a greater mechanical stress as only some parts of the weight-bearing surface may be involved (Hinterhofer et al, 2006a).…”

Weight and pressure distribution on the claw were studied in Swedish Holsteins housed in different flooring systems. A total of 127 cows housed in different sections of the experimental barn were used. Each section had different flooring in the walking and standing areas. There were rubber mats or abrasive mastic asphalt flooring on the alleys or a low-abrasive slatted concrete floor. Some sections had feed-stalls equipped with rubber mats; other sections did not. The vertical ground reaction force, contact area, and average contact pressure were determined on the left hind foot using the I-Scan system and analyzed with the F-scan system. These determinations were made in each of the following 3 zones of the claw: bulb, wall, and sole. Most of the weight on claws exposed to concrete floors was carried by the bulb (37.4 +/- 3.5 and 18.3 +/- 2.9% of weight exerted on the foot in the lateral and medial claw, respectively) and the wall zone (20.0 +/- 2.6 and 13.4 +/- 2.4% on lateral and medial claw, respectively). The weight and pressure distribution in cows kept on sections with rubber covered alleys but passing daily over the asphalt floor on their way to the milking parlor did not differ in any zones, except for lateral bulbs, compared with those exposed to slatted concrete alone. Still, the weight bearing of the sole zone in cows kept on rubber mats without access to asphalt was less than that of cows kept on concrete slatted floors (5.1 +/- 0.7 vs. 12.7 +/- 1.1% and 1.1 +/- 0.5 vs. 8.7 +/- 0.7% in lateral and medial claws, respectively). In cows kept on asphalt flooring without feed-stalls, most weight was exerted to the sole zone (36.2 +/- 2.9 and 22.2 +/- 1.8% in lateral and medial claws, respectively). Feed-stalls in combination with asphalt flooring yielded a decreased total contact area (30.1 +/- 1.2 cm(2)) compared with asphalt floors without feed-stalls (35.7 +/- 1.2 cm(2)). The largest total contact area was obtained on the asphalt floor without feed-stalls, resulting in a lower contact pressure (39.8 +/- 2.3 N/cm(2)) than in claws exposed to concrete (66.0 +/- 2.7 N/ cm(2)) or rubber mats (56.7 +/- 1.7 N/cm(2)). In conclusion, housing with abrasive floors resulted in claws with increased contact area at the sole surface and therefore, decreased contact pressure, but reduced the weight-bearing role of the strongest part of the claw capsule, the claw wall.

“…The supervision of the herd during the walking on asphalt roads showed cows aligning along the unpaved roadside as an attempt to improve their walking comfort, although data were not collected with a systematic methodological approach. This might prove that cattle prefer to walk and rest on soft soils rather than on hard ground, asphalt or concrete as observed by Telezhenko et al (2007), likely due to a more elastic ground surface that allows a uniform load transmission on the claws as suggested by Hinterhofer et al (2006). In addition, the driving down transhumance likely caused a slight metabolic alkalosis, resulting in the parallel decrease of calcium and magnesium, as suggested by Russell and Roussel (2007).…”

The study aimed at verifying if the prolonged walking and fasting of the driving down transhumance from an alpine pasture to the farm of origin at the end of the summer grazing may impair health and productive response of lactating cows belonging to two specialised dairy breeds. The study considered a herd of 380 dairy cows and heifers of Italian Holstein and Italian Brown breeds that faced a driving down transhumance with a vertical drop of about 1050 m. The animals walked for about 40 km completing the journey in 23 h, including three resting periods. Ten Holstein and nine Brown lactating cows were selected and monitored before and after the driving down transhumance taking individual blood samples and recording milk yield. The prolonged physical exercise and the limited water and energy intake during the driving down transhumance impaired cows' metabolic profile resembling a status of ketosis. A significant drop in milk yield was observed in all the monitored animals regardless of the breed. The production loss was more severe (49.4%) in cows with high milk yield and less days in milk. These animals required also a prolonged time to recover from the milk drop due to the driving down transhumance and, based on these findings, they should be excluded from this practise.

“…These authors also assumed this to be a primary factor in the development of claw horn lesions. Hinterhofer et al (2006) showed that mechanical stress is increased on slatted floors. On the contrary, heavier BW may also be a sign of overfeeding, with consequences for the metabolic condition.…”

A designed field study was conducted on 1,962 first-lactation Holstein cows kept on 7 large-scale dairy farms in Germany, in loose-housing systems on standard slatted flooring. Records of hoof disorders at trimming composed of subclinical as well as clinical cases were combined with body measurements and body condition scores, test-day records, and further individual cow data. The 6 most frequent disorders were laminitis, also known as sole hemorrhage (57.3% of all cows), dermatitis digitalis (17.0%), dermatitis interdigitalis (7.9%), white line disease (12.6%), sole ulcer (7.1%), and interdigital hyperplasia (5.5%). The most important environmental effects were herd-visit date and stage of lactation. Heifers between 50 and 99 d in milk had the highest frequencies for laminitis. Lighter cows were less susceptible to laminitis and white line disease, but had a higher prevalence of interdigital hyperplasia. Relationships between stature and white line disease as well as relationships between body condition score and dermatitis digitalis were nonlinear, resulting in an improved disorder status of cows with an intermediate condition score and average stature. Increased biomechanical stress caused by different factors (weight, social rank, standing time) is a presumed effect that leads to an increased susceptibility for hoof diseases. From a management perspective, under- and overconditioning should be avoided. Milk production traits differed between cows with and without laminitis-related claw horn lesions. Fat percentage and fat-to-protein ratio in the first month before trimming were significantly decreased for cows with a positive laminitis status. Hence, this finding points to metabolic disorders being associated with a higher risk for hoof diseases. Estimates of heritabilities for laminitis, dermatitis digitalis, dermatitis interdigitalis, white line disease, and sole ulcer were 0.09, 0.14, 0.10, 0.11, and 0.06 when applying a threshold model with a probit link function.
