Broiler-Housing Conditions Affect the Performance Rev. Bras. Ciênc. Avic.
Mesa,D; Muniz,E; Souza,A; Geffroy,B.
ABSTRACT In the last decades animal production has considerably increased worldwide to sustain an ever-growing human population. Among animal reared for consumption purposes, chickens are undoubtedly one of the most successful, mainly due to their rapid growth rate. The development of broiler farming has been accompanied in recent years by a substantial attention to animal welfare. This study is aimed at assessing the effects of different housing conditions on both feed conversion ratio and mortality of male broiler flocks through a large-scale study (more than 100 million birds) involving 977 farms belonging to one major producer. For this, we evaluated nine features of the housing system using a linear model with random effect. The features were:...

Employment as a factor increasing the population well-being in a social market economy AgEcon
Kuldurova, Batima.
The paper infers competiveness of a national economy in connection with the country’s capacity to provide sufficient and sustainable employment. The author argues the importance of reverse link that goes from sustainable employment and well-being in a country to competiveness of national economy. It is concluded that active social policy is important tool in providing impulses to competitiveness of economy,

Fat Taxes and Thin Subsidies: Distributional Impacts and Welfare Effects AgEcon
Salois, Matthew J.; Tiffin, J. Richard.
The extant literature on fat taxes and thin subsidies tends to focus on the overall effectiveness of such fiscal instruments in altering diets and improving health. However, little is known about the welfare impacts of fiscal food policies on society. This paper fills a gap in the literature by assessing the distributional impacts and welfare effects resulting from a tax-subsidy combination on different food groups. Using the methods derived from marginal tax reform theory, a formal welfare economics framework is developed allowing the calculation of the distributional characteristics of various food groups and approximate welfare measures of prices changes caused by a tax-subsidy combination. The distributional characteristics reveal that many of the food...

GM technology and the Australian canola AgEcon
Taing, William; Ahmadi-Esfahani, Fredoun Z..
In this paper, we use a simulation model to measure the potential market and welfare effects of recently introduced genetically modified (GM) canola in Australia. The short-run results indicate that non-GM canola may emerge as a niche product commanding a premium. In the long run, GM technology appears to enhance aggregate welfare. However, when production cost savings are trivial and consumers become highly concerned about GM food products, aggregate welfare may decline. The policy implications of the analysis are explored.

Production Indicators and Levels of Corticosterone in Pullets Treated with Beak-Trimming Protocols Rev. Bras. Ciênc. Avic.
Vieira Filho,JA; Garcia,EA; Oba,E; Santos,TA; Molino,AB; Silva,AP; Pelícia,K; Paz,ICLA.
ABSTRACT The aim of this study was to compare the effects of beak trimming by hot blade or infrared radiation on production indicators and plasma levels of corticosterone in pullets. During the rearing phase, an entirely random delineation was used a 2 x 3 factorial design (two different techniques for beak trimming x 3 strains), a total of six treatments with six repetitions of 20 hens. In the growing phase, the previous treatments were divided into 12, with eight repetitions with seven hens. These treatments were then distributed in a factorial design of 2 x 3 x 2 (two methodologies for beak trimming during rearing phase x three strains x with or without beak trimming at ten weeks of age). In the rearing phase the birds treated by infrared radiation had...

Welfare Changes from the U.S. Ethanol Tax Credit: The Role of Uncertainty and Interlinked Commodity Markets AgEcon
Baker, Mindy L..
A model of the corn, soybean, and wheat markets calculates welfare effects of the U.S. ethanol tax credit. Crop yields are uncertain, and demand consists of feed, food, energy, and exports. Modeling uncertainty in crop yields allows the valuation of deficiency payments as options. Disaggregating demand records who benefits from the tax credit and by how much; incorporating linked crop markets captures indirect effects important for determining the transfer from consumers to producers. There is $600 million in net welfare loss, increased taxpayer liability, and a large transfer from consumers to farmers. A brief comparison of recent literature is included.
