我们上周在奥地利。这个国家的人口超到800万,人年均消费猪肉50 kg(约119磅)。这是北美消费量的2.5倍。这里的人看起来健康且快乐,是否有什么神奇的原因? 相似文献

Nationwide surveys for the occurrence of Isospora suis were carried out in Germany, Austria and Switzerland including a questionnaire regarding herd size, health status and management practices and a coccidiosis sampling kit for pooled faecal samples from litters of suckling piglets. A total of 184 veterinary practices participated in the survey and returned 1745 samples (331 kits) from 324 farms in the north (n = 98), south (n = 84), centre/east (n = 42) and west (n = 10) of Germany, Austria (n = 61) and Switzerland (n = 29) with larger farms in north and centre/east (average number of sows: 270 and 500) and smaller ones in the south (95), Austria (60) and Switzerland (43). Larger farms tended to have better hygienic standards (slatted floors, disinfection of the farrowing units). The majority of the participating farms (93.5%) reported problems with diarrhoea in piglets at 2-3 weeks of age, significantly associated (P < 0.001) with uneven weaning weights (94.9%). Toltrazuril (5%; Baycox) was used only rarely; however, in these farms unevenness of weaning weights was less frequently observed (P = 0.011). A 76.2% of the farms were positive for I. suis (samples contained mostly low or moderate oocyst numbers), especially in the south (P < 0.001). Oocysts were more frequently found in samples from farms with reported diarrhoea (P = 0.011), uneven weight gain (P = 0.019) or in herds of small size (P < 0.001). Disinfection, floor type or treatment with toltrazuril did not affect the frequency of observation of oocysts. 相似文献

Distribution of antigen types of canine parvovirus in Switzerland, Austria and Germany 总被引:3,自引:0,他引:3

In this study the distribution of the various antigenic types of canine parvovirus in Switzerland, Austria, and Germany was investigated. From 14 samples from Switzerland, 35 samples from Austria, and 82 samples from Germany exclusively the new antigenic types CPV-2a and CPV-2b were isolated. Most of these isolates had a Ser-Val mutation at amino acid 297, which was shown to be prevalent in recent CPV isolates from various parts of the world. These findings are discussed with regard to the use of modified live virus vaccines. 相似文献
