Abstract:

AbstractIncreasing lameness problems associated with intensified dairy cattle production has lead to the development of several techniques to automatically detect these problems. Comparisons of these new measuring techniques of cow locomotion with the conventional subjective observer scoring are scarce. In order to better understand human observers’ gait scoring, cows walking on a pressure-sensitive mat were evaluated for kinematic gait variables and a visual assessment of gait was also made via video recording. Forty of these videos were used for subjective gait scoring on a 3-point scale, an

Abstract:

AbstractLameness is an indicator of pain and suffering, which has substantial animal welfare and economic impact on the dairy industry. Subjective locomotion scoring is unreliable for detecting mild cases of lameness in dairy herds. Undetected lameness can progress to a more serious and painful state with unfavourable prognosis. The aim of this study was to conduct an investigation on the use of a pressure plate for early detection of lameness in dairy heifers compared to a subjective visual scoring system. Seven heifers deemed sound, on the basis of a visual scoring system, were walked throug

Abstract:

Lameness remains a substantial challenge within the UK dairy industry despite significant investment and research in this area. The early detection and prompt effective treatment (EDPET) of new cases of lameness is vital in breaking the chronicity cycle associated with the condition yet remains an under-utilised approach. There needs to be a shift in focus away from using mobility scoring solely as an auditing tool. Mobility scoring should instead be used to empower producers to recognise early cases of lameness to maximise the long-term welfare of the animal and profitability of the unit.

Abstract:

Locomotion scoring is an important tool to detect dairy cow lameness. A number of locomotion scoring systems use the posture of the back to identify lame cows (score 3). For example Sprecher et al (1997) suggested the presence of an arched back standing and walking indicates lameness. Flower and Weary (2006) developed this system to score cows while walking where a score 3 cow has a more severely arched back than a score 2 cow. However to date no work has been published characterising the degree of arching of the spine observed in lame animals and its relationship with foot lesions. This is im

Abstract:

Lameness is a major welfare problem for dairy cows and has important economic consequences. On-farm detection of lameness is difficult, and automated methods may be useful for early diagnoses. Lameness may reduce the efficiency of automated milking systems (AMS) if lame cows are less willing to visit the automatic milking unit voluntarily and poor attendance at milking units may help detect lameness. To determine whether a low frequency of visits in an AMS could serve as an indicator of lameness, data on the frequency of visits of 578 cows in 12 AMS on eight farms were collected. From each AMS

Abstract:

As a major health problem facing dairy farmers worldwide with substantial economic, production and welfare consequences, lameness has attracted much attention over the last two to three decades (Boelling, 1999). Lameness as a linear type trait is measured by locomotion scoring as there is a high genetic correlation between lameness and locomotion score. Studies have included locomotion (as a predictor of lameness) and have associated lameness with no effect, an increase and sometimes a decrease in milk production of cows. Several reasons have been given for these differences and the need still

AbstractFour observers were trained in lameness assessment using a subjective scoring system with five categories, and observer agreement was investigated four times at different stages of training and experience. Inter-observer reliability increased with time and reached acceptable levels in the last session. Retrospectively simplified versions of the scoring system were satisfactorily reliable already at a fairly low training level. For experienced raters, the original scoring system with five categories is suitable in terms of reliability for on-farm welfare assessment.

Abstract:

The aim of the presented study was to validate a three-point locomotion score (LS) classifying lameness in dairy cows. Therefore, locomotion of 144 cows was scored and data on claw lesions were collected during hoof trimming. Based on latter data a cluster analysis was performed to objectively classify cows into three groups (Cluster 1–3). Finally, the congruence between scoring system and clustering was tested using Krippendorff’s α reliability. In total, 63 cows (43.7 per cent) were classified as non-lame (LS1), 38 (26.4 per cent) were rated as LS2 with an uneven gait and 43 (29.9 per cent)

Abstract:

Claw lesions and lameness in sows are important problems in the industry as they impair sow welfare and result in economic losses. Available scoring techniques to detect claw lesions are all limited in terms of collecting data during all reproductive phases and recording all claws. The Mobile Claw Scoring Device (MCSD) was designed to address these limitations. After considering different practical situations and a design phase, two prototypes were constructed and tested. Improvements were incorporated into a final aluminium apparatus, consisting of two cameras with light-emitting diode (LED)

Abstract:

Abstract Digital dermatitis (DD) is an infectious disease affecting cattle feet causing ulcerative and necrotic skin lesions. Most lesions are painful when palpated, some cause lameness and significantly impact animal welfare and productivity. Our objectives were: to determine if changes in behaviour were associated with DD in cattle, to quantify pain associated with DD lesions, and to determine the relationship between pain sensitivity and lameness, and DD and lesion temperature. In total, 255 animals across three feedlots were enrolled. A subset of 120 animals were fitted with accelerometers

Abstract:

Lameness is a serious animal welfare and production issue in the modern dairy herds. The development of a scoring system that is able to categorize the farm on the basis of its hazard risk level may help clinicians and farmers to identify potential issues and to reduce costs caused by lameness. The aim of this study was to develop an easy and fast score for evaluation of the structural and managerial factors potentially involved in the pathogenesis of foot lesions, and categorization of dairy farms. A total of six free-stall dairy farms were evaluated during a 3 month-period. The score develop

Abstract:

Abstract Though heat stress is becoming increasingly common in pig production, efforts are ongoing to mitigate the negative effects of heat stress on feed consumption. During a period of heat stress, 40 pigs (87.4 ± 0.86 kg) were fed oleic acid (0%, 2%, 4%, 6% and 8%, n = 8 per diet) to improve growth rate. With the rising concern for welfare issues in swine production, we sought to measure how the diet would affect lameness in growing pigs. Therefore, the objectives of this study were to 1) use thermal imaging as a noninvasive measure to detect lameness and 2) to measure effects of oleic acid

Abstract:

Models of transient synovitis that can be controlled with antiinflammatory and analgesic drugs have been used to study pain amelioration. To this end, we aimed to determine the dose of intraarticularly administered E. coli LPS that induced signs of synovitis without systemic signs in clinically healthy male castrated sheep (n = 14). In phase 1, a single dose of LPS (0.5, 1.0, 1.5, or 2.0 ng in a total volume of 0.5 mL) was administered into the right stifle joint. In phase 2, a dose of LPS (1.0 or 2.0 μg) in 0.3 mL was administered to 4 naïve sheep. In phase 3, 4 sheep from phase 1 were inocul

Abstract:

Lameness in cattle is a complex condition with huge impacts on welfare, and its detection is challenging for the dairy industry. The present study aimed to evaluate the association between foot skin temperature (FST) measured using infrared thermography (IRT) and locomotion scoring (LS) in dairy cattle kept at pasture. Data were collected from a 940-cow dairy farm in New Zealand. Cows were observed at two consecutive afternoon milkings where LS was undertaken at the first milking (4-point scale (0–3), DairyNZ). The next day, cows were thermally imaged from the plantar aspect of the hind feet u

Abstract:

Abstract Cattle mobility is routinely measured at commercial slaughter facilities. However, the clinical signs and underlying causes of impaired mobility of cattle presented to slaughter facilities are poorly defined. As such, the objectives of this study were 1) to determine the prevalence of impaired mobility in finished cattle using a 4-point mobility scoring system and 2) to observe clinical signs in order to provide clinical diagnoses for this subset of affected cattle. Finished beef cattle (n = 65,600) were observed by a veterinarian during the morning shift from six commercial abattoirs
