1 全国概况
4月份,全国饲料总体发展形势良好,较上年同期有较大幅度增长。水产饲料环比大幅增长,猪饲料、蛋禽饲料和反刍饲料环比均下降。据抽查,来自30个省、区、市169家饲料企业总产量为254．2万t,同比增幅28％,环比增幅9％。受3月份经销商和养殖户囤货影响,4月增幅略低于前期。同比增长幅度比上月低两个百分点,环比增幅比上月下降近九个百分点（表1）。 相似文献

This paper presents the main trends in the activity of European veterinary pathologists in the context of their oral presentations (plenary lectures and short presentations) and posters provided during annual meetings of the European Society of Veterinary Pathology (ESVP), in the decade 1997-2006. It was found that the issue that was most often brought up in the meetings was organ pathology (566 presentations). Infectious and parasitical diseases were only slightly less frequent (548 presentations). Oncology was another common issue (404 presentations). During this decade, 52 plenary lectures were presented, 765 oral presentations and 1 072 posters. Altogether, 1 889 presentations were made, which is between 127 and 238 per year. Research by Polish scientists accounted for 3.16% of all presentations. Additionally, the subject matter discussed at the annual meetings is analysed, and the trends in the development of veterinary diagnostic pathology and broad pathology education are indicated. It is shown that veterinary pathology enhances knowledge in the field of veterinary medicine by fulfilling a cognitive and diagnostic role. 相似文献

Evidence for the non-involvement of the uterus in the lifespan of the corpus luteum in the cyclic dog 总被引：1，自引：0，他引：1
Progesterone levels in peripheral blood of dogs were analysed during the cycle in which hysterectomy (n = 5) or sham surgery (n = 3) was performed as well as during the cycle of dogs (n = 5) hysterectomized at least one year prior to this study; the data were compared with the findings in control dogs (n = 3). The averages of the duration of the luteal period observed in the three experimental groups were not significantly different from those of control dogs. Immediately after surgery, the progesterone level decreased from 25 to 50% of the presurgical level, but returned to presurgical level in about four days. Prolactin levels were elevated for about 30 h after surgery. Nevertheless, the averages of the mean prolactin levels for each animal during the luteal period of the experimental groups were not significantly different from those of control dogs. It is concluded that in the dog, the uterus is not involved in the lifespan of the cyclic corpus luteum. 相似文献

To find possible associations between antinuclear antibody (ANA) pattern, ANA titer, and certain clinical changes and clinical laboratory test results in dogs, the veterinary medical records of 111 ANA-positive and 126 ANA-negative dogs were examined. Variables could not be found that had significant associations with ANA pattern (unlike the results in persons), because of the predominance of 2 patterns. A log-linear model for ANA titer adequately fit the observed frequency and included 2-way interactions between titer and polyarthritis, titer and hematologic disorders, and polyarthritis and lymphadenopathy. 相似文献

In a 4-year period nine dogs have been met in which there was incomplete growth of the radius. The condition was unilateral in eight dogs and bilateral in one. Two were littermates. The defect is due to premature cessation of growth of the distal growth plate of the radius but the cause of this is not precisely known. It is recognized by characteristic radiographic changes in radius length, elbow joint space and premature closure of the distal growth plate of the radius. A method of surgical treatment has been devised and has proved beneficial in five dogs. Zusammenfassung. In einer Vierjahresperiode wurden neun Hunde beobachtet, bei denen ein unvollständiges Wachstum des Radius vorlag. Bei acht Hunden war der Zustand nur auf einer Seite zu finden, bei einem Hund auf beiden Seiten. Zwei der Hunde gehörten zum gleichen Wurf. Der Mangel ist auf verfrühte Wachstumseinstellung der distalen Wachstumsplatte des Radius zurückzuführen, jedoch ist die Ursache davon nicht genau bekannt. Er wird an charakteristischen radiographischen Veränderungen der Radiuslänge, des Ellbogengelenkzwischenraums und vorzeitigem Abschluss der distalen Wachstumsplatte des Radius erkannt. Es wurde eine chirurgische Behandlungsmethode entwickelt, die sich bei fünf Hunden als nutzlich erwies. Résumé. Au cows d'une période de 4 ans on a observé 9 cas de croissance incomplète du radius chez des chiens; l'anomalie était unilatérale dans 8 cas et bilatérale dans un cas; deux chiens appartenaient à la même portée. L'anomalie est due à l'arrêt prématuré de croissance de la plaque de croissance distale du radius, mais la cause n'en est pas encore connue d'une manière précise. Le diagnostic se fait par les signes radiologiques caractéristiques, modifications de la longueur du radius, de l'articulation du coude et soudure prématurée de la plaque de croissance du radius. On a élaboré une méthode de traitement chirurgical, qui s'est montrée favorable chez 5 chiens. 相似文献
