The research of the Master thesis was carried out in 2005/2006 years in the Laboratory of the State Food and Veterinary Service of Klaipeda County, state and private poultry farms in Klaipeda County and in the Department of Infectious Diseases of the Lithuanian Veterinary Academy. The data was analysed applying the descriptive statistical analysis method. The Master thesis consists of 48 written pages, 7 tables, 10 figures and 56 references. The study aimed at analysing the Salmonellosis hazard in the poultry farms in Klaipeda County and preparing the plans for Salmonellosis prevention. The goals: to collect the data for epidemiological analysis; to analyse the hazards of Salmonellosis in poultry farms in Klaipeda County; to prepare the plans for Salmonellosis prevention. Bacteriological analyses were carried out according to Food and Feed Microbiology LST EN ISO 6579 standards; the horizontal method for the detection of Salmonella spp. (ISO 6579:2002) was applied. The commercial kits were used to identify Salmonella spp. In a year 2005, 15660 poultry keepers were registrated in Klaipeda County, with the total of 817960 birds, 797974 of which were hens. In 2005 there were analysed 1524 samples for Salmonellosis. About 40.4 % of the analysed samples were pooled samples of chicks 1 to 4 d old, in which the majority of pooled samples constituted the samples from boxes, bedding, faeces (282 samples). The pooled samples in the layer hens group amounted to 24.6 % of the total... [to full text]

This thesis was focused on monitoring production of dust particles in poultry farming. This measurement was made with the Dusttrak II 8530 which monitored the environment in the stable every 3 seconds for 24 hours. For monitoring were selected companies in the South Bohemian Region, specifically MTD Ústrašice and Farma u lesa. Results of Dusttrak measurements showed that none of the stables exceeded the permissible limits of dust particles. Additionally microscopic analysis of the samples of dust particles revealed that the main component of source of dust was feed mixture.

Muitos ácaros encontram condições adequadas de sobrevivência nesses ambientes. Neste trabalho estudamos a dinâmica da associação forética entre ácaros e coleópteros predadores, analisando a ocorrência, abundância das famílias de ácaros associadas a histerídeos, bem como a diversidade acarofauna, a ocorrência de forésia entre os mesmos, através do estudo das infrapopulações e infracomunidades e dos índices de prevalência, dominância e uniformidade em granja de aves poedeiras em São João da Boa Vista - SP. Foram usadas duas metodologias de coletas para este estudo: amostras coletadas manualmente do esterco e armadilhas de solo. Foram realizadas oito coletas nas estações do ano 2002 e 9 coletas no ano de 2001. Foram encontradas 4 espécies de ácaros associadas aos histerídeos. A família Ascidae foi registrada como sendo nova associação com histerídeos no esterco de granjas. A prevalência de ácaros foréticos predominou em Hololepta quadridentata / Abstract: Animal production systems under confinement are artificial agroecosystems which favor the development of an exuberant arthropod fauna, due to their high manure offer. These environments may provide adequate survival conditions for a number of mites. The purpose of this work was to study the phoretic association dynamics between mites and predaceous coleopterans, also focusing on the occurrence and abundance of histerids-associated mite families, as well as their infrapopulations and infracommunities, related indexes of constancy, dominance and prevalence. The sampling methodology included hand-collected manure samples and pitfalltraps. Eight gathering activities occurred in different seasons in 2002, and 9 gathering activities during the period of 2001. Associated to histerids 4 mites species were found. A new association has been found between histerids and the Ascidae family in poultry farms manure. Phoretic mites prevalence was prevailing in Hololepta quadridentata / Mestrado / Parasitologia / Mestre em Parasitologia

In the organization and management of poultry farming many problems arise which call for a solution. Among such problems are the following: The amount of floor space per hen which will prove the most economical, the value of electric lights in poultry houses, amount of labor which can be profitably invested in a poultry flock, and the amount of feed which can be economically fed to poultry. There are many influences which determine poultry profits that cannot be controlled directly, but the factors mentioned here are largely within the control of the poultryman. He should, therefore, direct them as far as possible so as to increase his net returns. Each hen should be provided with floor space necessary for most efficient production. The poultryman, however, does not know the amount of space that will bring the greatest returns. If the net income from each hen is just as high with two square feet of floor space per hen as where each hen has six square feet, then it is not economical to have six square feet of floor space per hen. If this is the case, it would be advisable for the poultryman to increase the size of his flock so as to obtain the fullest returns from his investment in poultry houses and equipment. A poultry farmer should know if there are any advantages derived from the use of electric lights. If it is an advantage to use lights, the poultryman desires to know how many hours they should be used each day. If, through the use of lights, production is increased to such an extent that gross returns more than pay for wiring, cost of electricity, and other incidental expenses, lights will prove a profitable investment. A poultryman must give time and labor to his flock in feeding, cleaning coops and gathering eggs. When this work has been efficiently done, extra time and labor is not likely to increase profits. The poultry farmer wants to know the point where increased labor fails to increase profits. This same principle applies to the amount of feed given to poultry. Up to a certain point production may be increased as the amount of feed is increased, but before this point is reached, the extra eggs may not pay for the additional feed costs. The poultry farmer should know the limits of poultry feeding which will prove profitable. whether or not the poultryman solves these problems determines to a considerable degree his success or failure. This study is an attempt to point out the relationship existing between several of these factors which pertain to the organization, management, and profitableness of poultry farm.

In this diploma thesis I focus on poultry farms, as a source of dust particles, which are taken from the breeding establishment to the surroundings of poultry breeding. The first theoretical part of the thesis is focused on dust, dust particles and their sources, as well as on housing of poultry and on BAT technology. These particles can be dangerous not only for the animals but also for the staff working in the vicinity of the farm animals. In the second, practical part of the thesis, I focus on the measurement of dust particles PM10 using the DUST TRUK II measuring instrument in a selected broiler breeding facility, as well as on the processing of measurement results and comparison with hygienic regulations and already measured values.

Antimicrobial resistance is a major global health challenge. It threatens the achievement of multiple SDGs with disproportionately negative consequences for LMICs. AMR is associated with the misuse of antibiotics, which is especially dominant in livestock farming. On-farm biosecurity has been identified as an effective way to prevent diseases. This requires a change in the daily behaviours of farmers. While the application of social-psychological models gained immense popularity in veterinary and agricultural research, these models lack predictive and explanatory character, leading to the so-called intention-action gap. The emerging field of behavioural sciences likely offers a better explanation of human behaviour, however, studies published often lack use of an explicit theoretical framework. Therefore, this exploratory study aims to address this gap by using Kahneman’s Dual-Process Theory as a theoretical framework for behaviour science studies. To this end, a qualitative study with 15 smallholder poultry farmers in rural Ghana was conducted. The findings suggested the presence of cognitive biases and heuristics that hinder farmers’ uptake of biosecurity measures, such as temporal discounting, social cues, cognitive overload, psychological inertia and habits. However, all factors must be considered, including knowledge gaps, as well as practical and economic constraints. It is clear from the study that farmers are not a homogenous group and that any promotion of biosecurity is destined to fail if they do not take farmers' psychological and contextual reality into consideration. Therefore, this thesis concludes that additional insights and hypotheses can be generated using behavioural science and that it offers a better and more holistic theoretical framework than currently used behavioural change models. Suggestions for further work include more empirical study in farmer decision-making related to on-farm biosecurity from a behavioural lens. Specifically, the use of quantitative and experimental methods to investigate and confirm the hypotheses that emerged from this study.
