Full textA cabra-montesa (Capra pyrenaica) é uma espécie endémica da Península ibérica, uma das mais emblemáticas do Parque Nacional da Peneda-Gerês. Contam-se 13 anos desde o regresso deste ungulado silvestre a território português depois de a espécie ser considerada extinta em 1890. A presença crescente de gado doméstico e assilvestrado, sobretudo de caprinos, nas áreas ocupadas pelas cabras montesas constitui uma das principais ameaças à conservação da espécie, quer devido ao aumento da prevalência e transmissão de doenças, quer devido à competição pelos recursos naturais. Posto isto, torna-se importante a monitorização e controlo deste tipo de rebanhos. Neste contexto, elaborou-se um estudo sobre a parasitofauna de 27 núcleos de caprinos residentes na área do PNPG através da recolha de 50 amostras de fezes, pertencentes a cabras-montesas (Capra pyrenaica, n=22), cabras domésticas (Capra hircus, n=20) e cabras assilvestradas (Capra hircus, n=8). Em Portugal, é a primeira vez que se realiza um estudo deste género na cabra-montesa. No total das 50 amostras, 98% (n=49) apresentaram formas parasitárias pertencentes a pelo menos um dos 9 géneros/espécies identificados e com as seguintes prevalências: Muellerius capillaris (100%, n=22 cabra-montesa, n=20 cabra doméstica, 75%, n=6 cabra assilvestrada), Nematodirus (100%, n=20 cabra doméstica, 95,5%, n=21 cabra-montesa, 25%, n=2 cabra assilvestrada), Teladorsagia (65%, n=13 cabra doméstica, 22,7%, n=5 cabra-montesa, 12,5%, n=1 cabra assilvestrada) Trichostrongylus (45%, n=9 cabra doméstica, 13,6%, n=3 cabra-montesa, 12,5%, n=1 cabra assilvestrada), Moniezia benedeni (35%, n=7 cabra doméstica, 22,7%, n=5 cabra-montesa, 12,5%, n=1 cabra assilvestrada), Dicrocoelium dendriticum (5%, n=1 cabra doméstica), Trichuris ovis (5%, n=1 cabra doméstica), Eimeria (70%, n=14 cabra doméstica, 59,1%, n=13 cabra-montesa, 37,5%, n=3 cabra assilvestrada) e Cryptosporidium (20%, n=4 cabra doméstica, 13,6%, n=3 cabra-montesa, 12,5%, n=1 cabra assilvestrada). De uma forma geral, a parasitofauna encontrada nas 3 populações foi muito semelhante, tendo-se registado intensidades parasitárias baixas, o que não invalida a necessidade da continuação de estudos de monitorização destas populações de caprinos.
ABSTRACT - Parasitological survey on wild, feral and domestic goat’s populations from Peneda-Gerês National Park - The Iberian ibex is endemic to the Iberian Peninsula, one of the most emblematic species from Peneda-Gerês National Park. Is has passed 13 years since the return of this wild ungulate to Portuguese territory, after this specie be considered extinct at 1890. The increasing presence of livestock, specially domestic and feral goats, at the Iberian ibex’s range, is one of the main threats to ibex conservation, either because of the increase of diseases prevalence and transmission rates, but also due the competition to natural resources. Therefore, it’s important to monitor and control these types of flocks. In this context, a parasitological study was developed in 27 goat’s nuclei inhabiting the national park’s range from the collection of feces bellowing to Iberian ibexes (Capra pyrenaica, n=22), domestic goats (Capra hircus, n=20) and feral goats (Capra hircus, n=8). In Portugal this was the first study of this kind on Iberian ibex. In a total of 50 samples, 98% (n=49) shown to be positive for at least one parasite of the 9 identified genera/species and there were the following prevalences: Muellerius capillaris (100%, n=22 Iberian ibex, n=20 domestic goat, 75%, n=6 feral goat), Nematodirus (100%, n=20 domestic goat, 95,5%, n=21 Iberian ibex, 25%, n=2 feral goat), Teladorsagia (65%, n=13 domestic goat, 22,7%, n=5 Iberian ibex, 12,5%, n=1 feral goat) Trichostrongylus (45%, n=9 domestic goat, 13,6%, n=3 Iberian ibex, 12,5%, n=1feral goat), Moniezia benedeni (35%, n=7 domestic goat, 22,7%, n=5 Iberian ibex, 12,5%, n=1 feral goat), Dicrocoelium dendriticum (5%, n=1 domestic goat), Trichuris ovis (5%, n=1 domestic goat), Eimeria (70%, n=14 domestic goat, 59,1%, n=13 Iberian ibex, 37,5%, n=3 feral goat) e Cryptosporidium (20%, n=4 domestic goat, 13,6%, n=3 Iberian ibex, 12,5%, n=1 feral goat). In general, the parasitic fauna encountered at the three goat’s population was very similar, with low parasitic’s intensity, but it cannot be underestimated the need of continuing the monitoring study’s on these goat’s population.

Full textCurrently the main impacts and threats to island communities include bioinvasions and standing out the goats between them. Most of the islands reported in the literature, are ecosystems where vegetation evolved in absence of large herbivores. On the island of Mallorca is well known the ancestral presence of a pre-human endemic ungulate, Myotragus balearicus, which suggests that herbivore was a selection factor constantly present to the vegetation in the island. Today, two goats that currently shared habitat and hybridized, have mainly occupied its ecological niche: the Wild Mallorcan Goat and feral domestic goats. The presence of these goats has generated many opinions about its effect on the vegetation of the island. Therefore, the aim of this thesis was to characterize and compare the botanical composition of the diet of the Wild Mallorcan Goat and feral domestic goat in Mallorca. Additionally, the browsing levels on the main components of the vegetation and the habitat use by both goats was evaluated in order to investigate possible differences in their social structure and behavior that help to elucidate the level of resource use and find possible evidences of climate change in the diet of extinct Myotragus balearicus. The study was carried out in six areas of the Sierra Tramuntana in Mallorca; three inhabited by the Wild Mallorcan Goat and three by the feral domestic goats. Microhistological analysis of faeces from each goat ecotype in spring, summer and winter for two years as well as the assessment of availability and browsing intensity of the most abundant species of vegetation were performed. Analysis of the feeding and social behavior in both goat ecotypes was conducted through focal in abovementioned seasons. Stomatal density and index of Buxus sp. epidermis fragments found in coprolites from extinct Myotragus were compared with actual epidermis of Buxus balarica and Buxus semprevirens to detect a possible manifestation of climate change. The diet of the Wild Mallorcan Goat and feral domestic goat was very similar especially in times of scarcity (Summer). Indeed, the possible damage on vegetation would be subject to an overpopulation of goats that goat ecotype itself. Both goat ecotypes showed a selective dietary behavior, with clear preferences and rejections, but also capable to adapt to availability because they use most species available. Few species are heavily browsed in all periods of the year, although the intensity of browsing by almost all studied species can be considered moderate. Some differences in the feeding behavior of the both goat ecotypes were found, especially related with herd size, suggesting a more efficient use of plant resources in the Wild Mallorcan Goat. The current density and stomatal indexes in B. balearica were considerably smaller than those found in Myotragus coprolites, which could be due to increased CO2. This thesis highlights the importance of a properly management of both goat ecotype populations so that ensure the conservation of animal and vegetal species.

Data from 10,238 weekly milk yield records from 388 first lactations of Saanen goats were used to evaluate the persistency of lactation under a random regression model. First, five models were compared (W035, W05, W0565, W068 e W10) generated by modifications of Wilmink function, assuming homogeneity of residual variance along the lactation. The value -0.05 was kept on model W05 while models W035, W0565, W068 e W10 used values -0.035, -0.0565, -0.068 e -0.10, respectively, in replacement to -0.05 value. After choosing the best model, six structures were evaluated for residual variance: homogeneity, two classes, three classes, four classes, five classes and six classes along the lactation. Subsequently, six different measures of persistency of lactation, adapted from those used on dairy cattle, obtained by replacing bovine reference values to goats ones on the expressions. AIC, BIC, ln L criterions and likelihood ratio test (nested models) were used on models evaluation. Model W035 presented the best fit among the evaluated ones. Relating to residual variance, the most indicated by used criterions was the structure of six classes. By presenting less genetic correlation with milk yield until 268 days (0.14), the persistency measure (PS4) obtained by the sum of genetic values, on period from 41st to 240th day of lactation, as deviations of yield at 40 days of lactation may be pointed for genetic evaluations. Because of the low heritability of this measure (0.03), few responses from selection are expected on this herd.
Utilizaram-se 10.238 registros semanais de produção de leite provenientes de 388 primeiras lactações de cabras da raça Saanen na avaliação da persistência da lactação sob modelo de regressão aleatória. Primeiramente, foram comparados cinco modelos (W035, W05, W0565, W068 e W10) gerados a partir de modificações da função de Wilmink, assumindo-se homogeneidade de variância residual ao longo da lactação. No modelo W05, o valor -0,05 foi mantido, enquanto nos modelos W035, W0565, W068 e W10 foram usados os valores -0,035, -0,0565, -0,068 e -0,10, respectivamente, em substituição ao valor -0,05. Escolhido o modelo, foram avaliadas seis estruturas para a variância residual: homogeneidade, duas classes, três classes, quatro classes, cinco classes e seis classes ao longo da lactação. Posteriormente, foram avaliadas seis diferentes medidas da persistência da lactação, que são adaptações de medidas utilizadas em bovinos de leite, obtidas por substituir, nas fórmulas, os valores de referência de bovinos pelos de caprinos. Os critérios AIC, BIC, ln L e teste de razão de verossimilhança (modelos aninhados) foram usados na avaliação dos modelos. O modelo W035 apresentou o melhor ajuste dentre os avaliados. Com relação à variância residual, a estrutura com seis classes ao longo da lactação foi a mais indicada pelos critérios utilizados. Por apresentar menor correlação genética com produção de leite até 268 dias (0,14), a medida de persistência (PS4) obtida pelo somatório dos valores genéticos, no período do 41o ao 240o dia de lactação, como desvios da produção aos 40 dias de lactação deve ser indicada para avaliações genéticas. Em razão da baixa herdabilidade desta medida (0,03), pequenas respostas à seleção são esperadas neste rebanho.

This study was performed with the aim of to evaluate the “in vitro” acaricidal activity of the oil of the seed of andiroba against Boophilus microplus, Rhipicephalus sanguineus and Anocentor nitens; the biological activity of the third stage larvae (L3) of Musca domestica and the activity of the oil of the seed of andiroba on the larval culture of gastrointestinal nematodes of goat and sheep. The acaricidal activity in the related species of tick was carried by means of the engorged females immersion test, using groups of 10 engorged females with three repetitions for treatment; for the test with the third stage larvae (L3) of Musca domestica it had been formed four repetitions with 10 larvae for treatment. Strips of filter paper measuring 8.5 x 1.5cm (L x W) were soaked in 0.3ml of the solutions and controls, and next, they were introduced in test tubes, adding 1.30g of vermiculite, being the tubes closed with absorbent cotton. Daily observations were made for detection of mortality of larvae, formation of pupae and adults emergence. The activity of the oil of andiroba on larval culture of gastrointestinalnematodes was determined by the calculation of the percentages of reduction of infective larvae for gram of faeces, using three repetitions. For each experiment it had been used dilutions of 100%, 50%, 30%, 25% and 10% (T1, T2, T3, T4 and T5 respectively) of the oil of the seed of andiroba, using tween 80 as detergent. Two groups had been formed as controls, one with deionized water and another one with tween 80 + deionized water. For the test of reduction of gastrointestinal infective larvae of nematodes, another group was added as positive control (doramectina). The results showed effectiveness of 100% for all the dilutions tested in the three species of ticks. In the test with L3 of de M. domestica, eight days after the accomplishment of the test, it was observed in the 100% concentration 20.0% of larval mortality and 62.5% of inhibition of emergency of adults, values significantly higher than those got in the other treated groups.In the test of reduction of gastrointestinal infective larvae of nematodes, effective reduction (> 90%) was obtained for 100%, 50% and 30% treatments in goat, and for all the treatments for sheep.
Avaliou-se “in vitro” a atividade acaricida do óleo da semente da andiroba contra Boophilus microplus, Rhipicephalus sanguineus e Anocentor nitens; a atividade biológica do óleo da semente de andiroba em larvas de terceiro estágio (L3) de Musca domestica e a atividade do óleo da semente da andiroba sobre o cultivo de larvas de nematóides gastrintestinais caprinos e ovinos. A atividade acaricida nas referidas espécies de carrapatos foi realizada por meio do teste de imersão de fêmeas ingurgitadas, utilizando-se grupos de 10 fêmeas ingurgitadas com três repetições por tratamento; para o teste com L3 de Musca domestica quatro repetições compostas por 10 larvas de terceiro estágio foram formadas. Tiras de papel filtro medindo 8,5 x 1,5cm (C x L) foram embebidas em 0,3ml das soluções do óleo de andiroba e controles, em seguida, colocadas dentro de tubos de ensaio, acrescentando-se 1,30g de vermiculita, introduzindo-se, então, as 10 larvas e vedando-se com algodão hidrófilo. Fez-se observação diária para detecção de mortalidade de larvas, pupação e emergência de adultos. A atividadedo óleo de andiroba sobre cultivos de L3 de nematóides gastrintestinais foi determinada pelo cálculo dos percentuais de redução de larvas infectantes por gramas de fezes (LPG), utilizando-se três repetições. Para cada experimento empregaram-se diluições de 100%, 50%, 30%, 25% e 10% (T1, T2, T3, T4 e T5 respectivamente) do óleo da semente de andiroba, utilizando-se tween 80 como dispersante. Formaram-se dois grupos controle, um com água destilada e outro com tween 80 + água destilada. Para o teste de redução de larvas infectantes de nematóides gastrintestinais, acrescentou-se um grupo controle positivo (doramectina). Os resultados revelaram eficácia de 100% para todas as diluições testadas nas três espécies de carrapatos. No teste com L3 de Musca domestica, após oito dias da realização do teste, na concentração de 100% obteve-se 20,0% de mortalidade larval e 62,5% de inibição de emergência de adultos, valoressignificativamente superiores aos obtidos nos demais tratamentos. No teste de redução do LPG de nematóides gastrintestinais, os resultados revelaram redução altamente efetiva (> 90%) no número de larvas totais para os tratamentos 100%, 50% e 30% em caprinos e em todos os tratamentos para a espécie ovina.

In this study, the Wood model was adjusted to1069 lactations curve from dairy goats, for three different situations of residual structure. At first, the errors were considered as independent for all lactations, in the second as autoregressives of first order also for all lactations and in the third as independent for lactations that showed no residual autocorrelation and autoregressives of first order for lactations that showed, respectively, according the Durbin- Watson test. These three situations were compared by the percentage of convergence and the average and coefficients of variation of the mean square errors (MSE) and coefficients of determination (R2) adjusted. Subsequently, estimates of the variance components and genetic parameters for total milk yield (MY), for coefficients of the Wood model (a, b and c ) and for milk yield at peak (ymax), time to reach the peak (Tmax) and persistency factor (pers) of each lactation were obtained using the procedure REMLF90 (MISZTAL, 2002), with the objective to determine the influence of residual autocorrelation on heritability (h2) and repeatability (r) estimates and of animals rank according to their breeding values. Two genetic evaluations were made, one for MY with coefficients of the Wood model and other for MY with ymax, tmax e pers. The statistical model included the random effects of animal, permanent environmental and error, the fixed effects of contemporary group (year - season of kidding), number of kids per birth, genetic groups and kidding order, and the days in milk (linear) and age at kidding (linear and quadratic) covariates. In the study of individual fitting of the Wood model to lactation curves differences between the three cases of residual structure were very small, then it was not possible to give a residual structure that results in better fit of the model of Wood. The low values for h2 and r estimates for a, b, c coefficients in this three situations indicated that the gains obtained by selection for the shape of the curve was small. The different residual structures used influence estimates of the parameters h2, r and the correlations between traits. In addition, caused differences in animals rank, based on their breeding values of all traits. Therefore, in applying the Wood model, the correction of errors that are not independent must be done.
Neste estudo o modelo de Wood foi ajustado à 1.069 curvas de lactações de cabras, sob três diferentes situações de estrutura residual. Na primeira, os erros foram considerados como independentes para todas as lactações, na segunda como autoregressivos de primeira ordem também para todas as lactações e na terceira como independentes e autoregressivos de primeira ordem para as lactações que não apresentaram e apresentaram autocorrelação residual, respectivamente, segundo o teste Durbin-Watson. Essas três situações foram comparadas entre si pelos percentuais de convergência, e pelas médias e coeficientes de variação (CV) dos quadrados médios do erros (QME) e dos coeficientes de determinação (R2) ajustados. Posteriormente, as estimativas dos componentes de variância e dos parâmetros genéticos para a produção total de leite (PL), para os coeficientes a , b e c do modelo de Wood e para produção de leite no pico (ymax), tempo para atingir o pico (tmax) e fator de persistência (pers) de cada lactação, foram obtidas utilizando-se o aplicativo REMLF90 (Misztal, 2002), com objetivo de verificar a influência da autocorrelação residual sobre as estimativas de herdabilidade (h2) e repetibilidade (r) e sobre a classificação dos animais de acordo com seus valores genéticos. Foram feitas duas avaliações genéticas multicaracterísticas de PL com a , b e c e PL com ymax, tmax e pers, por meio de um modelo que incluiu como efeitos aleatórios o animal, o ambiente permanente e o resíduo; como efeitos fixos o grupo contemporâneo (anoestação de parto), número de crias por parto, grupos genéticos e ordem de parto e como co- variáveis a duração da lactação (linear) e a idade da cabra ao parto (linear e quadrática). No estudo do ajuste do modelo de Wood às curvas de lactação individuais foram encontradas diferenças muito pequenas entre as três situações de estrutura residual, não sendo possível indicar uma estrutura residual que resulte em melhor ajuste do modelo de Wood. Os baixos valores de h2 e r para os parâmetros a , b e c sob as três situações indicaram que os ganhos obtidos pela seleção para o formato da curva foram pequenos. As diferentes estruturas residuais abordadas influenciaram as estimativas dos parâmetros h2 e r e das correlações entre as características estudadas. Além disso, levaram a diferentes classificações dos animais, baseadas nos valores genéticos de todas as características estudadas. Portanto, ao aplicar o modelo de Wood, a correção dos erros que não forem independentes deverá ser realizada.

Considering the importance of raising buffaloes to the national dairy farming, the objective of this study was to model variations in test-day milk yield (TDMY) during the first lactation of Murrah buffaloes by random regression models (RRM), using orthogonal Legendre polynomials (POL) and linear B-splines (BSP). A total of 15,161 test-day records from 1,158 first lactations of Murrah buffaloes breed from herds belonging to São Paulo state, Brazil, with calving recorded from 1988 to 2005, were analyzed. For TDMY, 38 weekly classes of lactation days were considered and analyzed using a single-trait RRM, including the additive genetic, permanent environmental and residual random effects. In addition, contemporary group, linear and quadratic effects of the covariate age of the buffalo at birth, number of milkings and mean lactation curve of the population, modeled using a fourth-order orthogonal Legendre polynomials, were included as fixed effects. Covariance functions of additive genetic and permanent environmental regression coefficients were equally modeled by POL (3th to 6th order) or linear BPL (4 to 6 knots). Residual variances were modeled considering 9 classes uniformly spaced. The (co)variance components of parameters were estimated by Bayesian inference, using the GIBBS3F90 software. The convergence of Gibbs chains was verified by graphic inspection and using BOA package from the R program. The post-gibbs analyses were performed using the POSTGIBBS1F90 software. The selection of the models was based on deviance information criterion (DIC). The average TDMY was 6.31±2.13 kg. The sixth order POL and six-knot BSP (knots at 8, 29, 57, 120, 239 and 267 days), with highest degree of complexity (51 parameters) were considered as the most suitable to describe the TDMY variation. The genetic parameters presented similar tendencies for both models, excepted for genetic variances and heritability, which showed low estimates at first lactation weeks for model BSP6. It was possible realize that, despite the low correlation between the predicted breeding value for 270-day milk yield and lactation persistency, the best models classified the bulls similarly. The results indicate that linear B-spline function with six knots was the most appropriate RRM to genetic evaluation of TDMY of Murrah buffaloes, given that parcimonious models with higher computational advantages to model variations of TDMY are most sought, and given the better control of heritability estimates of the edges of the lactation curve.
Ao considerar a crescente importância da bubalinocultura na pecuária leiteira nacional, objetivou-se com o presente estudo modelar as variações da produção de leite no dia de controle (PLDC) de búfalas da raça Murrah por meio de modelos de regressão aleatória (polinômios ortogonais de Legendre POL e B-splines BSP lineares). Para tanto, foram analisados 15161 registros semanais de PLDC provenientes da primeira lactação de 1158 búfalas da raça Murrah, com partos registrados entre os anos de 1988 a 2005 e pertencentes a rebanhos do estado de São Paulo, Brasil. As PLDC foram divididas em 38 classes semanais e analisadas considerando modelo animal de regressão aleatória - que incluiu efeitos aleatórios genético-aditivo, de ambiente permanente e residual. Adicionalmente, incluíram-se efeitos fixos de grupo de contemporâneo, a covariável idade da búfala ao parto (efeito linear e quadrático), número de ordenhas e as médias dos coeficientes da curva de lactação representativa da população (sendo esta ajustada por meio de POL de 4ª ordem). As funções de covariâncias relativas aos coeficientes de regressão aleatória dos efeitos genético-aditivo e de ambiente permanente foram igualmente modeladas por meio de POL (3ª à 6ª ordem) ou BSP lineares (4 a 6 nós). A estrutura residual foi considerada heterogênea, contendo nove classes de variâncias. Os componentes de (co)variância dos parâmetros foram estimados via inferência bayesiana, utilizando o programa GIBBS3F90. A convergência das cadeias de Gibbs foi verificada por meio de inspeção gráfica e o pacote BOA, do programa R. As análises pós-gibbs foram feitas utilizando o POSTGIBBS1F90. A seleção dos melhores modelos se deu pela utilização do critério de informação da deviance (DIC). A média de PLDC foi igual a 6,31±2,13 kg. Os modelos POL de sexta ordem POL6, e BSP com seis nós BSP6 (8, 29, 57, 120, 239, 267 dias), com maior número de parâmetros (51) foram considerados os melhores para descrever a variação da PLDC ao longo da lactação. De modo geral, os parâmetros genéticos apresentaram tendências semelhantes para estes modelos, à exceção das estimativas de variância genética aditiva e herdabilidade, menores nas primeiras semanas de lactação para o modelo BSP6. Verificou-se que, apesar de pouco correlacionados, os valores genéticos preditos para produção de leite aos 270 dias e persistência da lactação para os melhores modelos classificam os reprodutores de forma similar. O MRA mais recomendável para avaliação genética da PLDC de búfalos da raça Murrah é uma função B-spline (com seis nós), haja vista a procura por modelos mais parcimoniosos e com maiores vantagens computacionais para modelar variações da PLDC de búfalas da raça Murrah; e dado maior controle das estimativas de herdabilidade referentes aos extremos na curva de lactação.

Full textThe work to reduce greenhouse emissions created by humans is a question that is highly relevant today. The transport sector is the second largest emitter of greenhouse gases in the European Union. To reduce the greenhouse emissions from the transport sector the EU commission has said that some of the freight that currently is being transported by road must move to rail or sea transport in order to reach EU environmental targets. The scope of this study is to compare the greenhouse emissions based on fuel consumption from domestic container transport between Gothenburg and Stockholm. The different modes of transports studied were trucks, freight train and container ship. The study was conducted using an empirical case study to calculate the greenhouse gas emissions using empirical fuel consumption data. The case study was supplemented by an interview with a person with great insight in the transport business. The result from the study shows that from an environmental perspective container transport by rail should be used. Transport by road is still the best means of transport for time sensitive cargo. If transport by sea is to be an environmental option, there has to be adjustments on either ships or management or both.

Full textSince apple domestication, humans have progressively selected improved varieties, especially for traits linked with fruit quality, productivity or resistance to pathogens. The genetic bases underlying these traits have been explored thanks to genetic mapping in F1 segregating populations that only allows the study of a small part of the available genetic diversity. The aim of this work was to analyze the genetic bases of fruit quality and disease resistance against apple scab and fire blight, in collections of old apple varieties representing a much larger diversity. Genotyping of core collections was performed either with arrays of 8k and 480k SNPs or by resequencing of chosen genes. Signs of genetic differentiation were identified between cider and dessert apples and were partially linked to the polyphenols pathway. After studying linkage disequilibrium, both on a large and a small scale, an association genetics approach allowed the identification of genomic regions associated with the variation of several fruit quality traits. Especially, the top of linkage group 16 was found to be linked with acidity (locus Ma), firmness, juiciness and bitterness (LAR gene). Concerning the resistance of apple to fire blight, a region containing a homolog of the NPR1 gene (defense activator) was identified. This thesis allowed the refining of the putative localization of previously identified QTLs and the identification of new genetic resources that could be useful in future selection programs using marker assisted selection

The purpose of this study was to study on making fresh cheese from domestic goat milk and fermented whey. Test 1 was to compare the qualities of fresh goat cheese with different fat contents. Three fresh goat cheeses made by whole goat milk, low fat goat milk and skim goat milk. The milk was pasteurized and then cooled, a mixed strain culture of Lactobacillus acidophilus (BCRC 17064) + Bifidobacterium longum (BCRC 11847) (1:1) was added to the milk with 15% and was made the fresh goat cheese. After the cheese was made, the approximate composition analyzed for moisture, crude protein, milk fat and ash; and the other measurements such as moisture, pH value, titratable acidity, hardness, color, lactic acid bacteria count, fatty acid composition, amino acid composition, Sodium Dodecyl-Sulfate Poly-Acrylamide Gel Electrophoresis (SDS-PAGE) and sensory evaluation were determined. The results showed that lower protein content in cheese product (P<0.05) in fresh goat cheese made by higher fat content in raw milk. At 4℃ cold storage for 4 weeks, the moisture, pH value, titratable acidity, color and lactic acid bacteria count of all treatments of fresh cheeses showed no significant difference but the fresh goat cheese made by low fat goat milk was of the biggest hardness; the fresh goat cheese made by whole goat milk was of most fatty acid content and the fresh goat cheese made by skim goat milk has the less amino acid content. With SDS-PAGE, there was shown that αs2-casein, β-casein and κ-casein were decreased at week 4 in all treatments. On sensory evaluation, there were no significant differences among treatments. Test 2 was to investigate the effect of post- pasteurization of fermented goat whey. Fermented goat whey were made by the whey removing from fresh goat cheese and added with 25% sugar, then pasteurized and cooled, a mixed strain culture of Lactobacillus acidophilus (BCRC 17064) + Bifidobacterium longum (BCRC 11847) (1:1) was added to the whey at 5%, incubated at 37℃ for 6 hours and then storaged at room temperature for 8 weeks as control group; re-pasteurization with 80℃for 20 minutes and then storaged at room temperature for 8 weeks as contrast post-pasteurization group. During storage, pH value, titratable acidity, water activity (aw), lactic acid bacteria count, amino acid composition, SDS-PAGE and sensory evaluation were determined. The results showed the titratable acidity, L value and b value of post-pasteurization group was significantly lower than control group (P<0.05), and the aw is significant higher than control group (P<0.05). The amino acid content of both treatments were increased with storage. With SDS-PAGE showed that there was no change on β-lactoglobulin and α-lactalbumin at week 8. On sensory evaluation, the overall acceptability of post- pasteurization group with dilution rate 1:1 and 1:2 was significantly higher (P<0.05).

Most of meat ruminant livestock in tropics and sub-tropics utilizes locally produced by-products of pasture and crops to reduce feeding costs. However, these feed resources contain lower crude protein (CP) and higher fiber which is usually accompany with lower digestibility. The smallholders feeding domestic forages usually face problems of producing shortage in winter and unavailability of drying abounding hay during rainy season in spring and summer. Therefore, to overcome this problem and maintain adequate feed supply was to conserve hay into silage or haylage until winter to stabilize the supply throughout the year. Pangola grass is a popular tropical forage, but with lower content of CP than legume forage. Thus, we planted Pangola with legume forage; not only to improve the quality of forage, but also utilized the characteristics of symbiotic nitrogen fixation in legume to reduce the usage of nitrogen fertilizers. Coupled with proper harvesting period and storage, it showed the potential of stabilizing supply of domestic forage and decreasing the feeding cost of ruminants. As a result, the study was conducted to investigate the feasibility of applying domestic grass-legume mixture forage on meat goat production. Twenty-seven 4-month old Nubian cross Boer female goats were randomly divided into three groups. Goats in each group were assigned to 1 of 3 dietary treatments fed with different forage (control: Bermuda straw and alfalfa pellet, Pangola-alfalfa mixture haylage, and Pangola-alfalfa mixture hay). The experiment lasted for 10 weeks, first week for adaptation. Feed intake was recorded daily, body weight was meseared every two weeks throughout the experiment. The results showed that the quality of domestic grass-legume mixture was better than import Bermuda straw. According to in vitro gas production kinetics, the insoluble potential degradable fraction and cumulated gas production volume of the grass-legume mixture diet were greater than the diet of Bermuda straw and alfalfa pellet. Both of the treatments were significantly higher than control group on final body weight, total weight gain, average daily gain and total dry matter intake. In conclusion, domestic pangola-alfalfa mixture grass showed potential to replace import Bermuda straw and alfalfa pellet for feeding growing goats, not only increase growth performance but also decrease the feeding cost.

Because of economic development, consumers need high quality fresh goat milk more and more. Therefore, it is important to evaluate the quality of goat milk on different seasons, brands, and delivery routes. This study used visible and near-infrared spectroscopy to detect fresh goat milk and raw goat milk. Evaluated factors include three seasons, 16 brands of products, and 13 delivery routes. Sampling dates are from December 2011 to December 2013 on monthly base and sum up to 1570 fresh goat spectra and 585 raw goat milk spectra. Principal Component Analysis (PCA), Multiple Analysis of Variance (MANOVA) and Linear discriminant analysis (LDA) are applied to test their differences. MANOVA test results showed that 9 brands fresh milk and 11 delivery routes raw milk have significant differences in three tested seasons. LDA test results showed that the highest misclassified rate was 0.72 and the lowest was 0.27 for fresh goat milk. For raw goat milk the misclassified rate was 0.57 and 0.2 for the highest and lowest, respectively. These results are useful for dairy goat production and milk quality management.

Most feed ingredients are imported nowadays in Taiwan. Due to climate change, and energy crisis, the feed cost in animal husbandry is getting higher during the past years. In order to cut down the cost, to use domestic forages, crop residues, agro-industrial byproducts or non-conventional feed resources is an important issue. A total of 8 Alpine goats in mid-lactation were used in a cross-over design experiment. According to their milk yield, lactating goats were evenly assigned into two groups which were assigned as control diet group ( CD ) fed imported feed ingredients or domestic diet group ( DD ) fed completely domestic feed ingredients. The major constituents of CD were alfalfa hay, bermudagrass hay, corn, soybean meal, and alfalfa pellet; the major feed ingredients of DD were corn silage, peanut stover, soybean pulp, and brewers’ grains. Each experiment period included 14 days adaptation period followed by 4 days of sampling period. The results showed there’s no significant difference of dry matter intake between two groups ( CD: 1522 g/head/d; DD: 1449 g/head/d ), but the CD had higher intake and apparent digestibility of crude protein and non-fiber carbohydrates. The intake and digestibility of crude protein of CD were 318 g/head/d, and 84.5%; the DD were 230 g/head/d, and 74%. The intake and digestibility of non-fiber carbohydrate of CD and DD were 662 g/head/d, 90.0%; and 568 g/head/d, 85.9%. Although the DD had lower milk yield ( CD: 2079 g/head/d; DD: 1865 g/head/d ), and N retention ( CD: 19.4 g/head/d; DD: 2.3 g/head/d ) than the CD, the feed efficiency of them were not significantly different. The feed costs of CD and DD were NT$ 14.5 and 11.9 dollars/head/d, respectively. Based on feed intake and milk yield, the estimated profit were NT$ 54.3 and 51.2 dollars/head/d. The DD had lower cost but lower profit. Based on the above results, it still needs to improve the efficiency of DD. Crude protein and non-fiber carbohydrate intakes and digestibilities of DD deserve further improvement if higher milk yield and higher profit were demanded.

Full text由於中國獨特的社會和政治環境,小額信貸機構的發展有其特殊的軌跡。本研究以深入訪談和參與式觀察為主要研究方法,通過為期三個月的田野調查,對中國西部與北部的兩個非政府小額信貸組織進行了深入考察。研究發現,小額信貸組織正面臨無法同時達成雙重目標的困境;基於觀察與資料分析,本文提出,中國農村社區信任結構的轉型是小額信貸組織面臨多重問題的主要原因。隨著市場經濟的發展與城市化的加速,在日漸瓦解的熟人社會中,小額信貸機構的社會目標被其財務目標所壓制,導致原有的扶貧、婦女賦權等目標難以達成,更形成了目標替代的組織現象。
為深入探討小額信貸產業中目標替代的現象,本文從組織目標的合法性與可測量性兩個角度提出假設,指出當邊緣目標具有強烈的合法性和直觀的可測量性,便可能取代相對難以觀測的核心目標。最後,本文指出,為保證小額信貸組織不偏離原有的社會目標,需要設計一種新型的、獨立的測量工具,用以跟踪記錄小額信貸組織的社會影響,並將其作為判斷組織表現的核心因素。
Known as an innovative tool for poverty alleviation, microfinance has been widely spread in developing countries in the past few decades. It is commonly claimed that microfinance institutions (MFIs) can provide financial opportunities to those who are unable to obtain loans from the formal system, while at the same time maintain their institutional sustainability. This promise has attracted the interest of developing countries with large population in poverty, leading to a remarkable emergence of microfinance industry on the global stage.
Because of the special social and political environment, the development of MFIs in China has its unique trajectory. Based on interviews and participant observation, this three-month research focuses on two non-governmental MFIs in Western China and Northern China, revealing a plight of infeasible dual objectives and proposing an explanation from the angle of transformed trust structure. In a collapsing acquaintance community, the social objectives are suppressed by the demands of self-sustainability, thus violating the original intention of poverty alleviation and women empowerment, and leading to a phenomenon of goal displacement.
To further discuss the logic behind the goal displacement phenomenon in microfinance industry, two propositions are suggested from the angles of legitimacy and measurability of organizational goals. The findings indicate that to ensure the social objective of MFIs, an independent evaluation system is needed to track the social impacts and better assess organizational performances in microfinance industry.

Full textUntil recently, osteological studies into ancient diet and health have primarily focused upon human remains. As a result, these areas of research are still in their infancy in the field zoo-archaeology. Animals have paid a heavy price for many major human advances, such as those in agriculture and transport. This use (and often abuse) of animals has left many tell-tale signs in their teeth and bones. Along with the many advantages in animal exploitation have also come major problems for humans. Thus, infectious diseases passed from animals to humans must have long played a significant evolutionary role in the development of society. The zooarchaeological record could provide an extremely important temporal framework for exploring and understanding past and current issues of human health and animal welfare. This volume provides one of the first contributions to the field, and may stimulate many more.

Most of the elderly people in Taiwan are rich, free and able to make their own travel plans. In addition to convenient mass transportation, they consequently become potential customers in domestic tourist market. Understanding and analyzing the types of what their travel purposes are can help us explore some certain factors influencing how often they take a trip. This survey is based on 2001~2013 questionnaires of “The travel conditions of the seniors in Taiwan over the age of 60” from Tourism Bureau, MOTC. It aims to discuss if the rates of the elderly people who take a domestic trip rise, and analyze the relative types of taking a domestic trip by using probit model and multinomial probit model. The survey results show that: (1.) whether to take a domestic trip or not : Chances are that married female interviewees in the seventies with higher-educated background and high monthly pay would take a domestic trip. (2.) Types of travel purposes : Higher-educated interviewees living in downtown or in Taipei suburbs prefer to take a sport trip. Housekeeping or unemployed interviewees have little chance of taking this kind of trip. Divorced male interviewees or those who are in separation are more likely to take an eco-trip than married or unemployed ones do. The better education, pay and residence male interviewees in downtown possess, the less chance they would take a religious trip. Unmarried, professional or laboring female interviewees are much more interested in it instead. Higher-educated, professional, laboring interviewees are more likely to visit their relatives or friends by taking a trip. Married, widowed, unemployed or paid less than twenty thousand dollars per month male interviewees in downtown or Taipei suburbs don’t do so during the trip. (3.) According the analysis of the types of travel purposes, it suggests that taking a trip “simply” increase gradually every year. The survey recommends that the government should put the conditions and environment of all kinds of travel plans into consideration while promoting the elderly people to take a trip, which not only gives them more options but also offers more incentives to those who are unwilling to take part in any trips.

Full textAt the end of the 19th century close of the locality Hemmoor (Lower Saxony) an urn cemetery from the time of the Roman Iron Age was discovered, on that the so-called Hemmoor situla were found. The 32 fragments presented here were found during the anthropological examination of the cremated bone finds from six situlae. The most important piece of the finds is a chicken bone fragment dated into the period between the end of the 2nd up to the first half of the 3rd century. It represents an important evidence for the beginning of the animal husbandry of house poultry. The further bone remainders come predominantly from sheep or goats. The age determination resulted in that no one of the animals became hardly older than two years. In addition it was noticeable that most remainders come from the bones of the lower limbs. That bones carry not a lot of meat.
