| This analysis begins with a definition and discussion of productive advertising. Then, following Dixit and Norman, persuasive advertising is used to study the welfare effects of generic advertising by marketing orders. The study first examines horizontal competition when the competing advertiser is a monopoly, and results show that the socially optimal level of advertising for a competitive marketing order is positive only if advertising raises monopoly output. Next, advertising choices of a marketing order which sells its output to a monopolistic distributor are considered. If the distributor is a monopolist, then marketing order advertising raises welfare. This finding is in marked contrast to the results for the horizontal case studied by Dixit and... |

| A "hybrid" spatial price equilibrium model is developed to evaluate changes in production, consumption, and trade of feed and malting barley under alternative domestic and agricultural trade policy regimes. The analysis includes the economic welfare impacts of changes in various farm subsidy programs on the United States, Canada, Australia, and European Union (EU-15) which are the four major barley exporting countries in the world. The actions of competitive U.S. grain traders under the Export Enhancement Program cause feed barley exports to be segmented into two distinct markets. A spatial equilibrium is established in which the Canadian Wheat Board and Australian marketing boards behave as oligopolists in export markets under arbitrage conditions induced... |

| The quarantine policy decision-making process in Australia is subject to the principles of the World Trade Organisation's SPS Agreement. It is primarily based on the risks and associated economic costs accruing to producers in the event of disease entry. The costs of a quarantine measure in terms of forgone trade benefits are not considered. The impact associated with this asymmetric approach is identified by demonstrating the gains to consumers which may arise through liberalised markets using a case study of the Australian apple industry. A partial equilibrium analysis is used to show the impacts of apple market liberalisation, which can be expected to yield gains to consumers which are greater than the economic costs to on producers. |

| Locomotion deficiencies in broiler production cause poor welfare and lead to change in drinking and feeding behavior with consequent loss in weight gain. This research aimed to assess locomotion deficiencies in broiler chicken by analyzing the vertical peak force on both feet during walk. A chamber was built with an inlet ramp, a horizontal walkway in the middle and an outlet ramp. In the walkway a thin mat with piezoelectric crystal sensors was placed to record the step vertical peak force of the feet while walking on the force platform. The measurement system consisted of a mat with electronic sensors and software that allowed real time recording of the forces and the processing and analysis of data. Footage was taken from two digital video cameras and... |

| In this paper, two AI mitigation strategies are examined, quarantine and vaccination. Meanwhile, associated welfare changes are evaluated by using FASOM. Results found that changes of total national welfare of U.S are insignificant with or without vaccination. Once comes to livestock producers, impacts become significant although magnitudes are small. For example, under 20% demand shocks, vaccination strategy dominates no vaccination at the production, market and national level. However, vaccination has no advantage when there is no demand shifts. |

| It was evaluated the intake behavior of Nellore steers in system without shade (WS), and silvopastoral system (SP) maintained in star grass (Cynodon plectostachyus) in summer and winter. Twenty-four Nellore steers were used (12 in each system), mean age 18 months and weight of 294.5 kg. The design was completely randomized with two seasons, two treatments, 24 hours and 12 repetitions. The observations were conducted in three days, for 24 hours, with an interval of 15 minutes, with effect of the hour on the grazing behavior (GRAZ) with a maximum of 52.1% and lying ruminating (LYRUM) with a minimum of 12.3%, both at 14h. The lying idle (LYIDL) was influenced by hour with a minimum of 11,6%at 14h, and by season, with 23.9% in summer, and 13.9%, in winter.... |

| ABSTRACT The objective of this study was to evaluate the behavior of immunocastrated male pigs compared with females and castrated males during the period before and after full immunization. A total of 30 animals were divided into three treatments, with ten animals in each (females, barrows, and immunocastrated males). The experiment was divided into three periods: 70 to 80 days of age (period 1), 81 to 110 days of age (period 2), and 111 to 140 days of age (period 3). The behavior of animals during these stages was evaluated. Immunocastrated males showed a higher rate of aggressive and sexual behavior during period 2, which decreased after the second vaccine dose. Both barrows and immunocastrated males presented high locomotion in period 1, reducing the... |

| ABSTRACT The pre-slaughter management is one of the predisposing factors to the reduction in the quality of the carcass and broiler meat, mainly for being a stressful condition. This study evaluates the inclusion of lemongrass (Cymbopogon citratus Stapf) in the water used in the diet of pre-slaughter broilers for the first time. The carcass and meat quality parameters were evaluated. The experiment was carried out in the poultry production of an experimental sector of the Federal University of Grande Dourados - UFGD. A total of 2,594 broilers were distributed in an entirely randomized design in a factorial arrangement of 3x2x2, with three different lemongrass concentrations in the form of infusion (0. 1 and 5 g/L), two sexes and two genetic strains (Ross... |

| Morphological asymmetry has been described as a potential broiler welfare indicator, for interpreting the birds' ability to cope with the challenges that may affect its growth. The objective of this study was to evaluate the use of morphological asymmetry data to estimate broiler walking ability and welfare.dBroilers werefed diets supplemented or not with vitamin D. Toes were measured when birds were 42 and 49 days old using digital caliper.the left and right sides of the following four bilateral traits (tarsometatarsus length, outer toe length, mid toe length, and back toe length) were measured twice on intact alive birds by two different researcherh. Data from right and left sides were compared in the two treatments using the Student t-test, and... |

| Transgenic plants producing insecticidal protein derived from Bacillus thuringiensis (Bt) have been widely adopted since their commercial introduction in 1996. In 2009, 25 countries planted 134 million ha of transgenic crops. The widespread adoption of such plants has reduced use of conventional insecticides while attaining yield gains, thus providing economic, environmental and human health benefits. Because of Bt crops’ high pest control efficacy, there is concern that pests will develop resistance to Bt toxins so that Bt crops are less or no longer effective. To delay the evolution of resistance, the U.S. Environmental Protection Agency (EPA) currently requires Bt crop growers to also plant non-Bt (conventional) crops on a minimum percentage of their... |

| This paper develops an analytical model able to represent the decisions of an individual risk averse farmer facing variability in both prices and yields. A comprehensive set of stylised risk reducing policy measures is represented. A calibration of the model is used to run Monte-Carlo simulations and to obtain optimal responses. The main focus is the interaction between policy measures and market strategies in terms of impacts on production, welfare and risk. Risk reducing strategies that cover different sources of risk, such as price and yield variability, may be complementary for the farmers. Counter-cyclical area payments create incentives to bring land into production and their capacity to reduce farming risk is mitigated by the potential crowding out... |
