“…In our study, we compared the differences of gait cycle variables at cow level and showed that group L2 had significantly higher differences of stance and swing phases and peaks of foot load and toe-off between left and right MT, which was even the case in one cow without any signs of lameness. Tadich et al (2010) reported that locomotion scoring may not always be sensitive enough to detect foot lesions, and foot lesions can be present without any sign of lameness; thus, lameness does not appear until the lesion is moderate to severe.…”

“…The degree of lameness is described using a validated clinical gait-scoring system (Sprecher et al, 1997;Flower and Weary, 2006), this being a subjective method for assessing lameness. However, locomotion scoring requires observer training and may not be sensitive enough to detect slight gait alterations (Engel et al, 2003;Tadich et al, 2010). The difficulties in evaluating the stride and postural characteristics as well as the reproducibility of scoring mildly lame cows are most challenging (Engel et al, 2003;Holzhauer et al, 2005;Flower and Weary, 2006).…”

Changes in gait characteristics are important indicators in assessing the health and welfare of cattle. The aim of this study was to detect unilateral hind limb lameness and foot pathologies in dairy cows using 2 high-frequency accelerometers (400 Hz). The extracted gait cycle variables included temporal events (kinematic outcome = gait cycle, stance phase, and swing phase duration) and several peaks (kinetic outcome = foot load, toe-off). The study consisted of 2 independent experiments. Experiment 1 was carried out to compare the pedogram variables between the lateral claw and respective metatarsus (MT; n = 12) in sound cows (numerical rating system <3, n = 12) and the differences of pedogram variables across limbs within cows between lame cows (numerical rating system ≥3, n = 5) and sound cows (n = 12) using pedogram data that were visually compared with the synchronized cinematographic data. Experiment 2 was carried out to determine the differences across limbs within cows between cows with foot lesions (n = 12) and without foot lesions (n = 12) using only pedogram data. A receiver operator characteristic analysis was used to determine the performance of selected pedogram variables at the cow level. The pedogram of the lateral claw of sound cows revealed similarities of temporal events (gait cycle duration, stance and swing phases) but higher peaks (toe-off and foot load) as compared with the pedogram of the respective MT. In both experiments, comparison of the values between groups showed significantly higher values in lame cows and cows with foot lesions for all gait cycle variables. The optimal cutoff value of the relative stance phase duration for identifying lame cows was 14.79% and for cows with foot lesions was 2.53% with (both 100% sensitivity and 100% specificity) in experiments 1 and 2, respectively. The use of accelerometers with a high sampling rate (400 Hz) at the level of the MT is a promising tool to indirectly measure the kinematic variables of the lateral claw and to detect unilateral hind limb lameness and hind limb pathologies in dairy cows and is highly accurate.

“…The left-right differences of the stance-and swing-phase durations tended to decrease after claw trimming when cows walked on asphalt floor. Many studies reported that foot pathologies at certain stages (slight to moderate degree) do not affect the gait score of cows (Engel et al, 2003;Tadich et al, 2010). Furthermore, we excluded lame cows from the analysis, as a previous study showed that lame cows have different walking patterns on different floor types (Flower et al, 2007).…”

The locomotion comfort of dairy cows depends on the floor of the walking alleys. Optimal locomotion comfort is given when cows walk on pasture, allowing freedom from discomfort and pain and the expression of normal behavior. This study examined the characteristics of locomotion behavior on pasture (gold standard with optimal locomotion comfort) and compared it with behaviors of cows walking on mastic asphalt or solid rubber mats before and after a routine claw trimming session. Our hypotheses were (1) that gait variables were different on pasture versus mastic asphalt and on mastic asphalt versus rubber, and (2) that claw trimming had an effect on gait variables of cows walking on mastic asphalt. Twenty-four dairy cows kept in a tiestall facility were enrolled in this experimental trial. The pedogram was measured using 2 standalone 3-dimensional accelerometers (400 Hz), attached to the metatarsus of both hind limbs. The extracted pedogram variables included temporal events (kinematic outcome = gait cycle and stance-phase and swing-phase durations) and peaks (kinetic outcome = foot load, toe-off). The cows were further video-recorded to calculate walking speed and stride length. Locomotion score was performed on mastic asphalt to enroll only nonlame cows (locomotion score <3). For comparison between different floor types, repeated-measures ANOVA was performed with the cow as a subject variable, session time of measurement as within-subject variable, and flooring type as a fixed effect. Three separate analyses were performed: pasture versus mastic asphalt (analysis I), solid rubber versus mastic asphalt (analysis II), and the effect of claw trimming on the kinematic and kinetic variables on mastic asphalt (analysis III). All tested gait variables were significantly different between pasture and mastic asphalt floor. The optimal characteristics of locomotion comfort on pasture included shorter duration of gait cycle, longer stance-phase duration, shorter swing-phase duration, higher walking speed, longer stride length, and higher peaks of foot load and toe-off. However, gait variables of cows walking on rubber mats did not show any significant difference compared with the mastic asphalt floor; only stride length tended to be longer on rubber mats. In addition, the stance-and swing-phase durations significantly improved shortly after trimming. The left-right differences of the stanceand swing-phase durations tended to decrease after claw trimming when cows walked on asphalt floor. The results of this study show that solid rubber flooring does not result in significant improvement of the evaluated variables of locomotion comfort compared with mastic asphalt.

Como se ha indicado anteriormente, cuando un animal es afectado por un factor estresante, su organismo experimenta cambios fisiológicos que propician el incremento de la liberación de hormonas adrenérgicas y ingestion of foods that produce a lot of heat from fermentative processes.…”

The importance of behavioral and physiological biomarkers and their effects on the dairy production of dual purpose cattle was evaluated through the collection and analysis of the primary information. The database maintained by the University of the Amazon, the National University of Colombia, and SCIELO, was analyzed using the keywords: animal welfare, ethology and bovine behavior. It was observed that the activities to which the cows are subjected in dairy production lead to an inevitable stress for the animal due to the conditions of the system, negatively affecting the production, specifically the quantity and quality of milk produced (Total solids, fats and proteins). Greater knowledge regarding animal welfare will contribute to a better understanding of the behavior of dual purpose cattle in dairy production, subject to different management conditions. In this sense, ethology becomes a powerful tool that helps to understand how these animals perceive their environment.Keywords: Animal behavior, bovines, biomarkers (Source: CAB). RESUMENSe evaluó a través de la recopilación y análisis de la información primaria, la importancia de los biomarcadores conductuales, fisiológicos y sus efectos en la producción lechera de bovinos doble propósito. Se analizó la base de datos que mantiene la Universidad de la Amazonia, la Universidad Nacional de Colombia, y SCIELO, usando las palabras clave: bienestar animal, etología y comportamiento bovino. Se observó que las actividades a las que son sometidas las vacas en producción lechera conllevan un estrés inevitable para el animal debido a las condiciones mismas del sistema, afectando negativamente la producción, específicamente la cantidad y calidad de leche producida (Solidos totales, grasas y proteínas). Un mayor conocimiento en lo que se refiere a bienestar animal contribuirá al mejor entendimiento de la conducta del ganado doble propósito en producción lechera, sometido a diferentes condiciones de manejo. En este sentido la etología se convierte en una herramienta poderosa que ayuda a comprender cómo perciben estos animales su entorno.Palabras clave: Biomarcadores, bovinos, comportamiento animal (Fuente: CAB).
