“…In New Zealand, Tranter and Morris (1991) showed that a peak incidence of lameness occurred during the winter and the late spring, its onset being associated with wet weather conditions [16]; a similar trend was reported by Jubb and Malmo (1991) [17]. In the USA, there was little difference in seasonal prevalence of lameness in milking cows, 13.7% occurring in summer and 16.7% in spring [18]. Huang et al (1995) found that the season of highest risk for heel erosion, sole ulcer and laminitis was November and for white line separation it was July [19].…”

Seasonal and breed effects on the prevalence and type of claw lesions were investigated on 24854 cases of culled cows at central abattoir in the vicinity of Ardebil in Iran during twelve consecutive months. After recording information for each case, the feet were amputated and ground surface of the claws were pared for more morphopathological study. The prevalence rate of claw lesion among all cases was 24.2 per cent. The claws lesion in local cows (24.4 %) was more than imported Holstein cows (22.5 %) (P< 0.05). Most lesions occurred in the feet; the commonest were heel horn erosion (48.3 %), white line disease (25.1 %), laminitis (12.2 %), sole ulcer (10.3 %) and septic traumatic pododermatitis (4.1 %). There was a significant effect of the frequent claw lesions in each breed (P< 0.05). Heel horn erosion was the commonest lesion in Holstein cows (41.2 %) and local cows (49.1 %) and septic traumatic pododermatitis in Holstein cows (4.7 %) and laminitis in local cows (3.4 %) were the lowest lesions. White line disease was ranked second in Holstein cows (24.2 %) and local cows (25.1 %). Significant differences were not seen between the season and claw lesions (P> 0.05). However, data analysis also revealed that claw lesions occurred with greater frequency during the warm season in local and Holstein cows. The results obtained from this study demonstrate that lameness is an important problem in dairy herd in Ardebil. Poor management in hoof trimming, locomotion monitoring and poor quality of floors were the common causes of claw lesions.

“…Otro factor que puede influir es el mayor tamaño y peso de las vacas Holstein. Se menciona que por cada 100 kg de incremento en el peso vivo se aumentan 1,9 veces los cuadros clínicos de lesiones podales (Well et al, 1993).…”

ResumenLas lesiones podales (LP) constituyen uno de los problemas de salud más importantes en los hatos lecheros. El objetivo fue evaluar el efecto de factores genéticos y ambientales sobre la ocurrencia de lesiones podales en ganado lechero de Costa Rica. Se analizaron 130 844 vacas (417 895 lactancias) de 358 hatos usuarios del programa VAMPP (Veterinary Automated Management and Production control Programme) en el periodo 1990 a 2015. La frecuencia de reportes de LP fue de 16,7% y 7,0% por vaca y lactancia, respectivamente. Las LP más frecuentes fueron separación de línea blanca (34,3%), laminitis (13,0%) y úlcera de la suela (12,8%). Se realizó un análisis por regresión logística sobre la variable LP, mediante la cual se determinó efectos significativos de los factores: zona, hato dentro de zona, número de parto, tipo racial, periodo y mes de parto, etapa de lactancia, tamaño de hato; y el efecto aleatorio de vaca. Las vacas más propensas a LP pertenecieron a la zona bosque húmedo premontano (OR=1,76), tenían cuatro partos (OR=1,29), eran de raza Holstein (OR=1,77), parieron entre 1995 y 1999 (OR=1,73), abril (OR=1,20), estaban en segundo mes de lactancia (OR=22,2) y provenían de hatos con al menos 100 vacas (OR=1,22). La heredabilidad para LP estimada por modelos lineal y de umbral, fue de 0,02±0,002 y 0,05±0,004, respectivamente; y los estimados de repetibilidad fueron 0,03±0,001 y 0,05, respectivamente. Las vacas con LP presentaron 16,1 días abiertos adicionales. Hubo un alto impacto de esta enfermedad en los hatos lecheros evaluados.Palabras claves: factor de riesgo, salud animal, regresión logística, heredabilidad. AbstractFoot injuries are one of the most important health problems in dairy herds. The objective of this study was to evaluate the effect of genetic and environmental factors on the occurrence of foot injuries (FI) in Costa Rica's dairy cattle. A total of 130 844 cows (417 895 lactations) from 358 herds users of the VAMPP (Veterinary Automated Management and Production control Programme) software were analyzed between 1990 and 2015. The frequency of FI reports was 16.7% and 7.0% per cow and lactation, respectively. The most frequent FI were white line separation (34.3%), laminitis (13.0%), and sole ulcer (12.8%). FI was analyzed by a logistic regression, which determined significant effects of the following factors: zone, herd within zone, calving number, racial type, period and calving month, lactation stage, herd

“…Problems of lameness and restricted locomotion in loose housed dairy cows are to a large extent a result of housing system with concrete passageways. Lameness is negatively correlated with parity and most frequent upto 5 th parity due to increase in yield till 4 th to 5 th lactation (Wells 1993). Highest proportion of lameness observed in cow ageing more than 5 year.…”
