AHADO, S. – HEJKRLÍK, J. – RATINGER, T.Factors affecting participation in cooperatives and its impact on economic performance of farmers’ in Georgia. 2019, Factors affecting participation in cooperatives and its impact on economic performance of farmers’ in Georgia Samuel Ahado, Jiri Hejkrlik, Tomas Ratinger Cooperation among small farmers can be an important strategy for smallholders to remain competitive and efficient in rapidly changing markets. While there are theoretical arguments for the benefits of economies of scale and lower transaction costs associated with collective action, there are still few empirical studies that confirm these benefits in the post-Soviet eastern countries including Georgia. This paper estimates the determinants and performance of small farmers participation in relatively new producer groups established with the assistance of EU ENPARD programme in Georgia. Nearest neighbour, kernel and radius matching algorithms were used to estimate treatment effect. The counterfactual analysis deploys farm-level data of 210 respondents collected by the authors in 2018 using standardised structured questionnaires. Sensitivity analysis was conducted to check for hidden bias due to unobservable selection. Determinants of membership decision was established to be farm size, education and perception of the economic and social benefits of cooperatives. The findings of this study indicate that members of cooperatives exhibit higher gross margins and farm revenues than their non-member counterparts. The estimates were found to be relatively insensitive to hidden bias..

Abstract: There is an increased requirement for cheap and effective detection methods for safety and quality control in production animals. RnAssays has made possible the detection of bacterial, viral and/or parasitic infections and chemical contaminants simultaneously in a single test portion in a single analysis run, using flow cytometry. These tests allow for health profiles of herds to be established, as well as detecting transmissible diseases (zoonoses), residues of veterinary antibiotics at slaughter, simultaneous detection and chemical contaminants (Jankovska I., Miholova D. and Lukesova D. et al., 2012). RnAssays produces screening assays for a wide range of matrices including plasma, serum, eggs, and meat (drip) principally from pigs, poultry and bovine animals. A combination of fluorescent beads and a unique bead surface modification means that both chemical contaminants (e.g. antibiotic residues) and microbial contaminants (e.g. viral and bacterial pathogens and parasites) can be detected at the same time from the same sample. The combination of bead sizes with different fluorescent intensities creates powerful and flexible multiplex possibilities (Aldert A. Bergwerff, 2012). In 2010 the World Health Organisation estimated that every year, 2.2 million people around the world die from food infections, the majority of them children. Zoonoses represent one possible source of such infections (Lukesova et al., 1998). RnAssays range of Zoo Plex™ serology tests help food producers monitor animal herds to confirm the ongoing absence of zoonoses such as Salmonella, Toxoplasma, Trichinella, Taenia (cysticercosis) and others (Dubey, 2010). The SPF (Specific Pathogen Free) system introduced by Denmark is aimed at protecting pig herds from infection, limiting and preventing the spread of infection outbreaks and setting standards for animal transport. RnAssays is developing serological SPF Plex™ assays to meet this requirement for providing herd profiles with respect to animal diseases in a single multiplexed test. The Residue Plex™ assay uses monoclonal and polyclonal antibodies and natural capture agents in a competitive inhibition assay configuration. Discrimination of the individual microspheres is arranged by different bead sizes and bead internal fluorescent intensities, which lead to the analysis of multiple analytic results per sample. This new bead-based test, which detects e.g. T. gondii and T. spiralis antibodies simultaneously within each sample, can replace two indirect tests for the determination of respective antibodies separately, while performing equally well or better. This will bring significant savings for its customers in terms of financial resources and time and will deliver improved product safety. One of the advantages of a bead-based assay over ELISA is the possibility to determine multiple specific antibody responses per single sample run facilitated by a series of antigens coupled to identifiable bead-levels. In conclusion, this initial study of a novel bead-based assay capable of a simultaneous detection of serological antibodies against T. gondii and T. spiralis antigens indicates that the test results correspond very well to the infection status of the animals, and, furthermore, there is a substantial to excellent agreement with other indirect tests (Gertie CAM Bolkem, Aldert A Bergwerff and Frans Knapen, 2012). In order to estimate the applicability of this test for purposes of serological monitoring, further testing of sera from naturally infected animals is required. RnAssays tests are designed for the highest possible throughput with minimal manual intervention to allow the processing of a maximum of over 1900 samples per day..
