“…Location (Anil et al, 2007(Anil et al, , 2008 and severity (Pluym et al, 2011) of the lesions might determine whether a sow will show overt lameness or not. Additionally, hoof lesions may permit entry of infection that might spread upwards, affecting joints and other tissues (Penny et al, 1965). Therefore, prevention should include measures to discourage the development of hoof lesions.…”

ABSTRACT. Loose dry sow housing became mandatory in the European Union from January 2013 onwards. One of the major causes of injuries to sows' hooves and associated lameness is fighting on concrete/slatted flooring at grouping. Previous studies observed that in sows submitted to feed restriction, feed supplemented with dietary fiber reduced the time spent in the standing position and increased the time spent in the lying position. Therefore, we investigated the effect of increased levels of dietary fiber (7.2-7.5% crude fiber/kg dry matter) on the severity of hoof lesions of group housed sows in three Greek swine herds. The feet of 596 sows were initially examined for lesions upon their entry to the lactation facilities. Lesions scored included hoof hyperkeratinization, erosions or cracks and toe and dew claws overgrowths. When exiting the farrowing facilities they were offered recipes with increased dietary fiber throughout one or two subsequent gestations. Thirty-eight percent were re-examined for feet lesions during the first and sixty-two percent during the second lactation after initial examination. The proportion of sows with at least one lesion on any foot, at first scoring, was more than 95% in all herds. The most frequently and severely affected sites were the heel and the elongated toes and dew claws. The increased dietary fiber had no effect on lesion severity on any of the hoof sites considered.

“…The design of the farrowing pen, the floor construction, the treatment of the floor surface and the type and the amount of bedding material play a primary etiological role in the appearance and development of leg injuries in sucking pigs (Penny, Osborne, Wright and Stephens, 1971;Smith and Mitchell, 1976). Floor hardness is a factor that considerably affects health and well being.…”

One of the limiting factors in pig production is the ill health of the animals. Besides the effect of overt disease, subclinical disease and more subtle disturbances in health may be a continual problem affecting all production parameters. These disturbances range from reproductive problems such as infertility, neonatal health problems, gastrointestinal and respiratory problems during the growing-finishing period, and injuries at all production stages.The causes of many of these disturbances and losses are multifactorial, resulting froman interaction between different environmental factors (stressors) and the animals. Many health problems are not initially due to infections but infections may appear as a secondary factor. Where bacteria, viruses and parasites are involved, the pig's immune status and ability for immune defence is often the determinant for disease. Unfavourable environmental factors do not result in a specific disease if the agent is missing.When animals are housed, their life form is altered. Housing creates limits in their choices, freedom of movement, activities, and feeding. While pigs generally have a talent for adapting to the environment, modern production methods have made it difficult for some animals to cope with their situation. They become stressed, and especially if this stress is prolonged, negative effects appear, generally reflected in their state of health.
