A pesquisa objetivou avaliar o estado da arte da inovação no setor de saúde animal, tanto no sentido de saber como e o que está sendo produzido, quanto à verificação de possíveis interações com as universidades. Ainda, a ausência de trabalhos publicados avaliando os tipos de patentes depositadas, bem como os grupos de pesquisa que atuam, direta ou indiretamente, nesta área fortaleceu a necessidade de iniciar uma pesquisa nesse sentido. Assim, por meio do levantamento e classificação de patentes depositadas, no Brasil, por indústrias de saúde animal e universidades públicas bem com estudo dos grupos de pesquisa do CNPq, buscou-se verificar o perfil de produção científico/tecnológico entre os dois atores principais (públicos e privados). Além disso, pontuou-se o que existe de demanda e oportunidade para inovação em saúde animal e fez-se uma primeira análise do nível de interação entre os grupos de pesquisa, que poderiam representar oportunidades de inovação, e empresas. Os resultados mostraram que o perfil de produção científica e tecnologia dos dois atores envolvidos, indústria e universidades, é distinto. Observa-se que as empresas de saúde animal apresentam maior número de depósitos de patente nas áreas de produtos biológicos e antiparasitários, enquanto as universidades apresentam pesquisas mais diluídas em temas de interesse para o setor de saúde animal, o que foi verificado tanto nas patentes depositadas quando na avaliação dos grupos de pesquisa. Ainda, verificou-se que, dos grupos avaliados, poucos declaram alguma parceria com instituições privadas. De uma forma geral, está sendo produzido conhecimento muito valioso nas universidades brasileiras que pode ser trabalhado em prol de colocar novas alternativas de medicamentos e terapias veterinárias. Neste contexto, acredita-se que a maior cooperação entre universidades e empresas da área de saúde animal poderá beneficiar o mercado e a sociedade com novas soluções. / The goal of this research is to evaluate the state of art on innovation of the animal health sector, studying what has been produced and how, and the possible interactions with universities. The absence of published papers evaluating patents as well as the research groups that act, directly or indirectly, in the area of animal health have strengthened the need to initiate this research. Thus, through the survey and classification of patents registered in Brazil by animal health companies and public universities, as well as the evaluation of CNPq research groups, we sought to verify the scientific / technological production profile between the two main parties (public and private). In addition, this work pointed iut the existing demand and opportunity for innovation in animal health and an initial analysis of the level of interaction between research groups and companies was made. The results showed that the scientific - technological production profile of the two parties is distinct. It was observed that animal health companies showed greater registration of patents on the areas of biological and antiparasitic products, while universities had patent registration more distributed on the topics of interest for animal health. These observations were true for both, registered patents and research groups do not state a partnership with a private company in the animal health industry. In general, information is created in Brazilian universities, and it can be used on the development for new alternatives for veterinary medicines and therapies. In conclusion, it is possible that greater cooperation between universities and animal health companies could benefit the market and the society with new solutions.

Metazoan parasites threaten the development and expansion of yellowtail kingfish (Seriola lalandi) sea-cage aquaculture in Australia. There is international speculation that parasite transmission from farmed to wild fish leads to increased incidence of parasitism in wild fish. Conversely, transfer of parasites from wild fish to farmed fish can negatively impact upon the health of farmed fish. Baseline information on the parasite assemblage of wild S. lalandi in Australia will: 1) allow informed judgments to be made in order to responsibly monitor, and perhaps remedy, potentially negative impacts and; 2) enable identification of parasite species of potential harm to the Australian S. lalandi aquaculture industry. I collected wild Seriola spp. (Carangidae) throughout southern Australia and examined them for metazoan parasites. Fifty-six metazoan parasite species are identified, including one new species. A taxonomic listing is provided for the metazoan parasites found. Taxonomic descriptions are made for the blood fluke Paradeontacylix godfreyi n. sp. (Digenea: Sanguinicolidae) and a redescription is provided for the parasitic copepod Naricolax chrysophryenus (Cyclopoida: Bomolochidae). A qualitative risk assessment was devised for the metazoan parasite taxa identified for the sea-cage aquaculture of S. lalandi in South Australia. Risk was interpreted considering the likelihood and consequence of parasite establishment and proliferation. The monogeneans Benedenia seriolae and Zeuxapta seriolae were considered extremely likely to establish and proliferate. Benedenia seriolae also poses high potential negative consequences for cost-effective S. lalandi sea-cage farming. However, the absence of potential mitigation methods and parasite management for Paradeontacylix spp. (Digenea), Kudoa sp. and Unicapsula seriolae (Myxozoa) indicates that these species may also present high negative consequences for S. lalandi aquaculture in Australia. The nature of wild Seriola migrations is critical for an understanding of the potential impact of disease and parasite interactions between wild and farmed fish. A small-scale tagging programme of wild-caught S. lalandi and S. hippos in South Australia provided insight into the movements of these species. Recapture results indicate that large S. lalandi remain in, or return to, northern Spencer Gulf. S. lalandi also move past sea-cage farms in Fitzgerald Bay, northern Spencer Gulf, which is an important consideration in view of potential expansion of the S. lalandi sea-cage industry in Spencer Gulf. There is surprisingly little experimental assessment on parasite transmission from farmed fish to wild fish. Studies assessing parasite interactions between wild and cultured fish employ models to quantify parasite population levels of cultured, wild and escaped fish, while others carry out comparative surveys of parasite prevalence and intensity over time, in areas close to and distant from farming activity. I provide preliminary data on ectoparasite prevalence and intensity on wild S. lalandi in areas close to, distant from and where there is no sea-cage farming in southern Australia. I review methods employed in the northern hemisphere to assess sea-louse transfer between wild and farmed salmon and propose methods for assessing monogenean parasite transmission from farmed to wild S. lalandi in Australia. In summary, this thesis provides insight into the potential for parasite interactions between wild and farmed S. lalandi. I document the parasite assemblage of wild and farmed S. lalandi and wild S. hippos and provide baseline data on ‘natural’ parasite prevalence and intensity. I provide a taxonomic description of a new species of blood fluke. I indicate the likelihood of parasite transfer from wild fish to farmed S. lalandi, and identify parasite taxa with potentially negative consequences for sea-cage aquaculture. I provide the first firm data that wild S. lalandi move past one area where kingfish are farmed in sea-cages in South Australia. Finally, I propose procedures to better understand the potential for monogenean parasite transmission from farmed S. lalandi to wild fish. This thesis reports new information that is important when considering and managing expansion of the S. lalandi sea-cage aquaculture industry throughout Australia. It also provides baseline data on natural parasite levels to enable ongoing monitoring of the potential impacts of the industry on wild fish populations. / http://proxy.library.adelaide.edu.au/login?url= http://library.adelaide.edu.au/cgi-bin/Pwebrecon.cgi?BBID=1294807 / Thesis (Ph.D.) -- University of Adelaide, School of Earth and Environmental Sciences, 2007

Yearly calvings are essential to the sustainability of modern dairy farming. Currently, calving difficulty (or dystocia) affects one in six calvings among UK dairy herds but vary from 2 to 50% internationally. In dairy cows, despite reports of impaired performance, the extent and threshold of the effect of dystocia on health and performance remains unclear. Over the past years, there has also been increasing concerns about the levels of pain experienced by the dystocial cows. Better understanding of their parturition progress and behaviours is needed so that informed decisions on pain mitigation can be taken. Additionally, the impact of dystocia (besides stillbirth) should also be addressed in dairy calves. The objective of this study was to address the effects of a difficult calving on the health and welfare of both dairy cows and calves. Retrospective analyses of an experimental farm’s detailed records were used to relate calving difficulty with health and performance of the dairy cow. The results showed that after any difficulty at calving, dairy producers incur long-lasting shortfalls in milk sales. Dystocial cows also have impaired fertility, are more likely to leave the herd early and have a higher risk of dystocia at the following calving, thus there is a long-term detrimental impact on dystocial cows. Video monitoring of calvings allowed detailed investigation of the parturition progress and behaviours of dystocial Holstein cows giving birth to singleton liveborn calves. The study of calving behaviours and parturition progress indicated longer later stages of parturition, increased restlessness and tail raising in the six hours preceding expulsion of the calf, for dystocial cows receiving farm assistance compared with cows calving unaided. This may relate to the expression of higher levels of pain when dystocia occurs. The onset of maternal behaviour was not delayed following calving difficulty, and firm conclusions could not be drawn from investigation of some behavioural indicators of pain in the first three hours postpartum. Experimental work allowed the monitoring of a cohort of 496 calves born with various degrees of birth difficulty over two years. All but one vet assisted calves were born dead, and farmer assisted calves were more likely to be stillborn than calves born without assistance. Stillborn dystocial calves displayed larger internal damage, than stillborn eutocial calves, but they did not have a different body shape at birth than dystocial calves that survived. Dystocial dairy calves that survived the birth process had lower vigour at birth, had higher salivary cortisol, acquired lower passive immunity and received more health treatments in the neonatal period. Dystocial heifers also had higher mortality rates by weaning but had similar growth to first service. Historical records from the farm also showed that dystocial heifer calves were three times more likely to have died by weaning and by first service than calves born without assistance. For those who survived, there was, however, no indication of altered growth to weaning or subsequent impaired fertility. This may be explained by the early mortality of the most badly affected calves or by farm management. However, their high mortality rates still raise welfare concerns. Altogether, results suggest that dairy calves born with any difficulty have poorer welfare in the neonatal period and possibly beyond. The experience of any calving difficulty in dairy cattle therefore not only impairs the welfare of the cow, but also the welfare from their resulting calf. Any strategy implemented to lower the occurrence and mitigate the effects of dystocia will therefore improve the welfare of the cows, their calves and enhance the farm’s economic sustainability.
