Studies were conducted to determine basic aspects of intake and digestion of native pastures by young sheep in the Falkland Islands, and to evaluate practical methods to improve the productivity of these animals. The studies were conducted in support of Industry and Government initiatives to reinvigorate Falklands’ agriculture. The current industry is based on broad diameter wools harvested from sheep grazing poor quality native pastures, and sheep suffer low growth rates, poor productivity and high mortality, and farmers rely on small flocks to produce a single commodity for their total income. The dramatic collapse of wool markets in the 1980’s crippled the Falklands’ wool industry and farmers have relied heavily on subsidies for more than 12 years. The studies in this thesis were initiated to support the efforts to reinvigorate Falklands’ agriculture, and they examined basic aspects of the nutrition provided to sheep by native pastures and evaluated practical methods to improve the survival of sheep, their subsequent rate of growth and productive value to the economy. Five studies examined specific hypotheses posed at the outset of the research programme and they were broadly supported by the data presented in the thesis: · A wether trial was used to benchmark the productivity of wool sheep in the Islands, and the trial demonstrated that substantial genetic variation exists within the national flock that may be exploited in the future to improve the productivity of the wool industry, · Microhistological techniques were used in conjunction with n-alkane marker technology to investigate the diets consumed by sheep grazing native pastures. The diet studies concluded that the low quality of native pasture in the Falklands during autumn, winter and spring restricts growth and productivity of young sheep, · Studies with weaner sheep treated with controlled release anthelmintics established that infection with gastrointestinal nematodes exacerbates poor nutrition of young sheep consuming native pastures, · A short-term metabolism study demonstrated that native pasture hay fortified with molasses and urea, or winter forage crops may be used as supplements to enhance sheep productivity, and · Forage crops were grown and evaluated under Falklands’ conditions, and when lambs were fed the resulting highly productive and nutritious forages, the study demonstrated that lamb growth can be increased significantly, and lamb carcasses offer local farmers the potential to diversify farm income by using existing Falklands’-bred lambs to develop an export meat industry The data presented in this thesis demonstrate that the potential to improve the productive and financial position of Falklands’ farmers is substantial. If both the local Industry and Government maintain their joint commitment to industry-restructure, pastoral development and enterprise diversification, the Falklands’ agricultural economy stands to benefit considerably by adopting low risk solutions to address widespread problems.

Svensk ull har länge blivit behandlad som en biprodukt. I dagsläget nyttjas ungefär 30 procent av den svenska ullen och resterande mängd antas slängas eller brännas på grund av ett bristande ekonomiskt incitament. Norge å andra sidan har sedan länge en väletablerad ullindustri som sköts med hjälp av statliga subventioner. Därtill sorteras och klassificeras norsk ull utifrån en ullstandard vilket gör att de lyckas nyttja 80 procent av sin råvara. En svensk motsvarighet av en standard finns inte i nuläget. I denna studie blandas kvalitativa intervjuer med en kvantitativ enkätundersökning för att undersöka svenska textil- och modeföretags inställning till att införa en ullstandard. Studien undersöker även möjliga åtgärder som kan vara nödvändiga att vidta för att svensk ull ska kunna nyttjas mer än vad den idag gör. Enkätundersökningen behandlar svenska textil- och modeföretag och efterfrågar deras vanor i hantering av ull samt deras inställning till en eventuell svensk ullstandard. Intervjuundersökningen delger information från respondenter längs ullens textila värdekedja. Resultatet av studien visar att det finns en positiv inställning till en svensk ullstandard, dock kan en tveksamhet synas hos vissa respondenter som bland annat menar att det blir för komplext. Vidare visar studien att en otillräcklig infrastruktur, bristande kunskap i ullhantering och låg efterfrågan är problem som svensk ullindustri har. Vid åtgärdade problem kan svensk ull som resurs förväntas nyttjas i större omfattning. / Swedish wool is being put aside as a by-product. At present, approximately 30 percent of Swedish wool is utilized, where the remainder is assumed to be burnt or discarded due to a lack of economic incentive. Norway, on the other hand, has a well-established wool industry that is managed with help from government subsidies. In addition, Norwegian wool is sorted and classified through a wool standard, helping them to utilize 80 percent of their raw material. A Swedish equivalent to a standard does not currently exist. In this study, qualitative interviews are mixed with a quantitative survey to examine Swedish textile and fashion companies’ attitudes towards implementing a wool standard. The study also examines potential measures that may be necessary to take in order for Swedish wool to be utilized more than it does today. The survey is addressed to swedish companies and asks about their habits in wool and attitudes towards a potential swedish wool standard. The interviews provide information from respondents along the wool’s textile value chain. The results of the study show that there is a positive attitude towards a wool standard, however, a hesitation can be seen in some respondents who, among other factors, think the entire process becomes too complex. Furthermore, the study shows that inadequate infrastructure, lack of knowledge in woolhandling and low demand are problems that the Swedish wool industry has. By addressing these issues, Swedish wool as a resource can be expected to be utilized more.

Generally, the heritability of each trait was high, which indicates that both the fleece and skin traits should respond well to selection. / Thesis (Ph.D.)--University of Adelaide, Dept. of Animal Science, 2001

Doctor of Philosophy / Department of Agricultural Economics / Hikaru H. Peterson / The U.S. wool demand has declined since 1950s due to the increasing demand for synthetic fibers. This research aims to study U.S. consumers' preferences for wool attributes to help the wool industry developing marketing strategies targeting certain groups of consumers. This research can be divided into two parts: 1) examining consumers' willingness-to-pay for wool attributes including country-of-origin, organic, animal-friendly, environment-friendly, and 2) investigating whether or not the consumer segments can be identified from consumers' demographic and psychographic characteristics on product purchasing behavior with respect to the wool attributes. In order to achieve the purpose of this research, the choice experiment was applied to examine consumers' preferences for wool attributes. Both mail and on-line surveys were conducted. The mail survey included three versions: basic version, version with definitions of attributes, and version with both definitions and information about wool attributes, with ## responses received (a 29 percent response rate). The on-line survey contained the basic version and the version with both definitions and information about wool attributes, with 514 responses received. Conditional logit and multinomial logit models were used to examine willingness-to-pay for wool attributes and consumer segments, respectively. Results indicated that a certain portion of U.S. consumers preferred wool over acrylic products. Findings also suggested that it is likely beneficial for wool producers to differentiate their products by promoting products' attributes, such as organic, animal-friendly, and environment-friendly. Further, brief information on product attributes provided with labels could increase consumers' WTPs. Results here revealed that to increase wool producers' revenues effectively, it is necessary to advertise their value-added wool products to different consumer segments.
