Résumé : |
In the Republic of Ireland the gross annual output of undressed hides and skins and manufactured leather goods exceeded £16 million in 1976. Whilst the hides of some countries command high prices because of their consistent good grading and consequent suitability for the manufacture of high priced goods, local hides are often down-graded because of defects of the grain or upper surface. Damage may occur ante-mortem. Post-mortem damage may occur at the time of flaying, as a result of poor storage or when processed.
Tancous et al. (1959) considered that stable flies, horn flies and sucking flies caused leather damage but produced no experimental evidence, however Everett et al. (1977) provide evidence that in the United States the prime cause of damage was bard ticks, with Demodex bovis (the hair follicle mite) also being important.
In a preliminary survey conducted in the Republic of Ireland, Baker (1973) showed the most common defect to be that of multiple scratches with consequent down-grading. He considered the cause to be ectoparasites. To substantiate the hypothesis that the multiple scratch defect results from ectoparasitism the following survey and experiments were undertaken. |
