中国草原立法中法律责任规定之不足与完善

通过对《草原法》及13个省、自治区20部草原法规中违法行为的法律责任进行梳理,整合分析2009年至2018年《全国草原违法案件统计分析报告》中的8类违法行为数据发现,其中违反草原禁牧休牧规定、非法临时占用使用草原、非法开垦草原、违反草畜平衡规定4类违法行为案发率高且对草原破坏性大;对这4类违法行为的法律责任分析,比较上...     

The impact of federal drug regulations on food animal practice.

This article discusses some of the regulations governing the use of drugs in ruminants. Because drug disposition is so influenced by dose, duration, and disease status, it is difficult to publish specific withdrawal time information. A discussion of calculation of withdrawal times is included.     

Experiences with the silicone T-tube in man and dog

Silicone T-tubes are particularly useful for long-term stenting of the laryngotracheal airway. Silicone is useful when non-autogenous non-reactive soft material is wanted for use in the human and animal body. Two case reports illustrate the use of the silicone T-tube.     

Cattle transport regulations in the European Union

The essential items of the relevant EU legislation are described and their effects are discussed. A brief survey of the four most important legal regulations in the EU relevant for cattle transport is given from the point of view of administration. These regulations are: The Directive 91/628/EEC 1991 (protection of animals during transport), Council Regulation (EC) No 1255/97 (criteria for staging points and route plan), Council Regulation (EC) No 411/98 (additional standards for road vehicles for long distance transport), Commission Regulation (EC) No 615/98 (export refund regulations). Some critical points of the objectives are pointed out.     

Experiences with a BVD-free transhumance in the summer of 2006

The aim of this paper was to examine the effect of eliminating persistently infected (PI) animals on BVDV infection during transhumance and to identify possible weak points in the prevention of new infection. An initial blood sample (A) was taken from all the animals until one week before the date of trans-humance (n = 190) and examined for virus by means of real-time RT-PCR or antigen-ELISA and for antibodies by means of ELISA. One PI animal was identified and eliminated. On the day of transhumance (B), serology was performed of the blood samples of all animals that had had a negative or unknown antibody status (n = 93) when blood sample A had been examined. At the end of the transhumance season (C) those animals that had tested seronegative in sample B were re-examined for antibodies (n = 65). The case incidence per animal year amounted to 37.1% up to sample A, 41.8% between sample A and sample B (4 seroconversions). Four cases of seroconversion were diagnosed during the transhumance season, which equalled a case incidence of 17.8% per animal year. A season of transhumance free of PI animals failed to completely prevent BVDV infection, but the new infection rate was significantly diminished. The most possible explanation for new infections are abortions of PI-animals.
