Shechita (Kosher slaughtering) and European legislation.

Shechita is the procedure of killing or slaughtering animals for food production, according to Jewish tradition and it is performed without prior stunning. USA and European legislations conditionally allow slaughter without prior stunning in the frame of religion freedom (USA) or religious/cultural traditions (EU); nevertheless some traditional events in Europe de nitely represent a concern for animal welfare. It is possible to identify animal welfare issues in the rules for shechita: correct restrain of the animal; adequacy of the instrument (knife); technical ability of the operator. Animals restrain techniques evolved along the time in order to accomplish to less stressful immobilization of animals in course of shechita. When performed in the right way, shechita cannot be framed as negligent or intentionally painful, distressing or inducing su ering to animals. Today's stunning techniques raise concerns relative to adequacy and e ectiveness of stunning on animals, with welfare implications due to automatism of next dressing procedures. Shechita needs in Europe are in line with average meat demand by non Jewish population.

First detection of Sarcoptes scabiei from domesticated pig (Sus scrofa) and genetic characterization of S. scabiei from pet, farm and wild hosts in Israel.

In this report we describe for the first time the detection of Sarcoptes scabiei type suis mites on domestic pigs in Israel and examine its genetic variation compared with S. sabiei from other hosts. Microscopic examination of skin samples from S. scabiei-infested pigs (Sus scrofa domesticus) revealed all developmental stages of S. scabiei. To detect genetic differences between S. scabiei from different hosts, samples obtained from pig, rabbits (Orictolagus cuniculus), fox (Vulpes vulpes), jackal (Canis aureus) and hedgehog (Erinaceus concolor) were compared with GenBank-annotated sequences of three genetic markers. Segments from the following genes were examined: cytochrome C oxidase subunit 1 (COX1), glutathione-S-transferase 1 (GST1), and voltage-sensitive sodium channel (VSSC). COX1 analysis did not show correlation between host preference and genetic identity. However, GST1 and VSSC had a higher percentage of identical sites within S. scabiei type suis sequences, compared with samples from other hosts. Taking into account the limited numbers of GST1 and VSSC sequences available for comparison, this high similarity between sequences of geographically-distant, but host-related populations, may suggest that different host preference is at least partially correlated with genetic differences. This finding may help in future studies of the factors that drive host preferences in this parasite.

Acute maduramicin toxicosis in pregnant gilts.

Ionophores are used as feed additives for the control of coccidiosis and growth promotion in farm animals. Reports of maduramicin toxicosis in farm animals are scarce. The present work describes an acute maduramicin toxicosis affecting 22 pregnant gilts, 2 pregnant sows and 2 boars, resulting in a total mortality of 65% within 2days. The clinical and histopathological findings observed shared similar characteristics to acute ionophore toxicosis in pigs, being characterized by severe myodegeneration in skeletal muscle and degenerative changes in the myocardium. Important clinical pathology indices found were elevated levels of CPK and ALT. In contrast to the pregnant gilts, the two pregnant sows completely recovered after 1month and farrowed 2months after the intoxication event healthy piglets. The lack of effect of maduramicin on the fetuses might be indicative of poor placental penetration of maduramicin. Moreover, the present work reports for the first time maduramicin levels in livers (0.5mg/kg) of gilts exposed to lethal concentrations of maduramicin (18.5mg/kg) in the feed. As the average feed intake of the gilts was estimated to be 3.5kg feed/day, the mean maduramicin intake leading to the observed high mortality rate was 0.4mg/kg body weight/day.
