“…Carvalho et al (2007) reported that trimmed cows had a more confident and stable walk. This was confirmed by Aoki et al (2006) who quantitatively indicated that walking characteristics improved after trimming by increasing walking rate, step length and stepping rate. Limb angles also showed less 'on tiptoe' locomotion after trimming.…”

To tackle the high prevalence of lameness, techniques to monitor cow locomotion are being developed in order to detect changes in cows' locomotion due to lameness. Obviously, in such lameness detection systems, alerts should only respond to locomotion changes that are related to lameness. However, other environmental or cow factors can contribute to locomotion changes not related to lameness and hence, might cause false alerts. In this study the effects of wet surfaces, dark environment, age, production level, lactation and gestation stage on cow locomotion were investigated. Data was collected at Institute for Agricultural and Fisheries Research research farm (Melle, Belgium) during a 5-month period. The gait variables of 30 non-lame and healthy Holstein cows were automatically measured every day. In dark environments and on wet walking surfaces cows took shorter, more asymmetrical strides with less step overlap. In general, older cows had a more asymmetrical gait and they walked slower with more abduction. Lactation stage or gestation stage also showed significant association with asymmetrical and shorter gait and less step overlap probably due to the heavy calf in the uterus. Next, two lameness detection algorithms were developed to investigate the added value of environmental and cow data into detection models. One algorithm solely used locomotion variables and a second algorithm used the same locomotion variables and additional environmental and cow data. In the latter algorithm only age and lactation stage together with the locomotion variables were withheld during model building. When comparing the sensitivity for the detection of non-lame cows, sensitivity increased by 10% when the cow data was added in the algorithm (sensitivity was 70% and 80% for the first and second algorithm, respectively). Hence, the number of false alerts for lame cows that were actually non-lame, decreased. This pilot study shows that using knowledge on influencing factors on cow locomotion will help in reducing the number of false alerts for lameness detection systems under development. However, further research is necessary in order to better understand these and many other possible influencing factors (e.g. trimming, conformation) of non-lame and hence 'normal' locomotion in cows.

Video recordings of cows walking with markers are later analysed with software for kinematic variables (Flower et al, 2005;Aoki et al, 2006;Blackie et al, 2013). Another technique uses image preprocessing, in which video recordings are transformed into sequences of binary images to facilitate the detection of anatomical parts of cows (Song et al, 2008;Van Hertem et al, A c c e p t e d M a n u s c r i p t 2013; Viazzi et al, 2013).…”

“…Walking rate, step length and stepping rate were measured in accordance with protocols previously described (Aoki et al . ). Briefly, digital camcorder still pictures were captured consecutively on a personal computer by using freely available software (Area61 Video browser), and the three kinematic measures were calculated by using image analysis software (Adobe Photoshop CS4 Extended, Adobe Systems, Tokyo, Japan).…”

“…; Telezhenko & Bergsten ; Aoki et al . ), the ‘support phase’ was defined as the period between when each hoof touched the floor (hoof strike) and when it lifted off the floor (hoof off). The difference in hoof positions between the start of the first support phase of one forelimb and the start of the last support phase of one forelimb (regardless of the limb side) was regarded as the walking distance.…”

This study investigated how supplementation of the diet of dairy cows with trace minerals (zinc, manganese, copper and cobalt) affected kinematic gait parameters and lactation performance. Eight Holstein cows were divided into two groups, with each group receiving a different dietary treatment (control diet, or control diet supplemented with trace minerals) in a two-period crossover design. Kinematic gait parameters were calculated by using image analysis software. Compared to cows fed the control diet, cows that received the trace mineral-supplemented diet exhibited significantly increased walking and stepping rates, and had a shorter stance duration. Feed intake and milk production increased in cows fed the trace mineral-supplemented diet compared with control groups. The plasma manganese concentration was not different in control and experimental cows. In contrast, cobalt was only detected in the plasma of cows fed the supplemented diet. These results provide the first evidence that trace mineral supplementation of the diet of dairy cows affects locomotion, and that the associated gait changes can be detected by using kinematic gait analysis. Moreover, trace mineral supplementation improved milk production and only minimally altered blood and physiological parameters in dairy cows.
