| Résumé : |
The investment in raw material represents by far the single largest cost to the leather processor yet it is the element that he frequently has the least control over. The life cycle of meat animals offers many opportunities for damage to occur including on the farm, during transport, slaughter, and preservation. Work at BLC has investigated the impact of ectoparasites, specifically the biting louse, Bovicola bovis, on hide quality and appropriate measures to control this commonly occurring pest. In trials involving over 500 cattle, the impact of exposure and treatment with commercial ectoparasiticides was evaluated and leather quality and value assessed accordingly. Animals slaughtered while infested with lice gave hides with low grades and significant levels of light spot and fleck damage. Animals slaughtered having been cleared of lice for a minimum of 6 weeks gave hides with reduced levels of fleck and this improved further up to 13 weeks, although full resolution of damage did not occur. Animals kept lice free throughout their 2 year life span consistently gave hides of high quality with no light spot damage. A further trial evaluated the impact of treating calves at 12 weeks of age and keeping them lice free to slaughter at 2 years compared to calves that did not receive lice treatment in their first year. The untreated calves developed natural lice infestations and their hides displayed higher levels of light spot damage at both chrome tamed and dyed crust stages. The findings of this work suggest that lice cause damage to bovine hides that may demonstrate elements of resolution or healing but is unlikely to resolve completely following treatment. |
