水生观赏动物活饵料应用技术展望

在水生观赏动物的人工育苗中,幼体阶段的活饵料是育苗成功的关键之一。本文着重探讨了轮虫（如褶皱臂尾轮虫）、卤虫、桡足类（如日本虎斑猛水蚤、哲水蚤等）、枝角类（如蒙古裸腹涵和西藏拟泾）等饵料浮游动物的营养特点、培养利用现状及其在水生观赏动物养殖中的应用前景。为水生观赏动物养殖中活饵料使用和开发新的饲料蛋白源提供参考。     

出口食品生产企业信息化管理初探

我国出口食品生产企业的数据管理大多数都停留在纸质文档管理的阶段,而食品生产过程原辅料繁多、加工过程复杂,传统的数据管理方式既难以适应现代化的生产,也不利于食品的追溯追踪,影响食品安全。本文从出口食品生产企业信息化管理的角度出发,详细分析成都地区出口食品生产企业的生产经营特点以及在信息化管理方面存在的相关问题。根据相关的特点和问题,提出出口食品生产企业信息化管理的总体规划、建设目标以及相关细则。旨在通过建立信息化的数据管理手段,实现对食品生产企业的现代化管理,有效实现食品整个环节的追溯和追踪,保障食品安全。     

Cost implications of improving food safety in the Dutch dairy chain

This paper examines control measures for improving food safetyin the dairy chain, using an integer linear programming model.The chain includes feed (compound feed production and delivery),farm (dairy farm) and dairy processing (transport and processingof raw milk, delivery of pasteurised milk) blocks. Results showthat 65 per cent of the maximum possible food safety improvementcan be achieved at relatively low extra cost per ton of milk(4.27), fairly evenly distributed across the blocks. Highersafety levels can be attained by increasing the farm block'scontribution, but at much higher extra cost (44.37 for the maximumattainable).

我国粮食补贴政策体系的构建与完善

我国的粮食补贴政策,经历了由间接补贴到直接补贴发展的过程。现行的粮食补贴政策,在促进粮食增产、农民增收,确保国家粮食安全方面,发挥了积极的作用。但是在政策的实施过程中,也确实存在着一些不容置疑的问题,针对粮食补贴政策中存在的主要不足,就如何完善我国的粮食补贴政策,更好地实现政策目标,进行了思考并提出相应的建议。     

Food Aid, Food Prices, and Producer Disincentives in Ethiopia

Although the short-term aims of food aid are well conceived, strong concerns have been voiced regarding the long-term impacts of such aid on incentives for agricultural producers in recipient countries. This article examines the statistical link between food aid shipments and food prices in Ethiopia over the period 1996–2006. Monthly data from three markets and three commodities are used to estimate a system of seemingly unrelated regression models for food prices. Results indicate that previous year food aid shipments reduce prices in all producer and consumer markets. These effects, however, appear to be limited to the set of internationally traded commodities that are domestically marketed. A recursive regression procedure is used to identify the food aid threshold at which a negative aid effect emerges. Food aid shipments that constitute less than 10% of domestic production appear to be benign, but shipments above this level show signs of being disruptive to local markets. We use a simple policy simulation to argue that production-sensitive targeting, e.g., conditioning food aid on local food production, would help to circumvent disincentive effects.

Market Incentives for Safe Foods: An Examination of Shareholder Losses from Meat and Poultry Recalls

Meat and poultry recalls, while voluntary, are carried out under governmental oversight. If firms have financial incentives to avoid being implicated in a recall situation, governmental involvement in recalls may cause firms to internalize social costs when making investment decisions concerning food safety controls. To examine these incentives, we analyze federally supervised meat and poultry recalls from 1982 to 1998 within an event study. Results show significant shareholder losses when publicly traded food companies are implicated in a recall involving serious food safety hazards. We find no evidence that the stock market reacts negatively when recalls involve less severe hazards.     

Gender,entrepreneurship and food security in Niger

In many African countries, the income generated from the informal sector and the entrepreneurship is particularly important for reducing poverty. Previous studies have not found clear evidence on the relationship between self‐employment by gender and food security. We argue that this may be a result of the gender inequality in resource accessibility. In this paper, we analyze the implication of household entrepreneurship on food security in Niger, where gender disparities in resource accessibility are reduced. We find that owning female‐managed non‐agricultural enterprises is positively related to food accessibility and food availability within female‐headed households. The results draw the attention on reducing gender differences in resource accessibility in entrepreneurship for improving food security.
