Texto completoAmong fattening pigs you find several stereotypical behaviours, such as bar-biting and tail-biting. These behaviours are quite common among domestic pigs. Environmental enrichments are often used to reduce stereotypical behaviours in animals. An environmental enrichment is defined as an improvement of an animal’s welfare, both psychologically and physiologically, through changes in the environment of the animal. With this study, different environmental enrichments were studied to see if they can reduce stereotypical behaviour among fattening pigs. The two different environmental enrichments used were a jute sack filled with straw and a Jolly Ball™. The stereotypical behaviours that were looked at were bar-biting, tail-biting and belly-nosing. The study was carried out on 107 pigs divided into 12 pig boxes, during 3 weeks in total. All three stereotypical behaviours decreased significantly. This shows that the environmental enrichments had a positive effect on the pigs, since they reduced their stereotypical behaviour. The pigs interacted more with the jute sack than they did with the Jolly Ball™. The pigs preferred the environmental enrichment that was destructible, edible, deformable and chewable, which fits well into similar studies that have been executed.

Texto completoThis PhD Thesis is related to optimisation of pig fattening phase under an operative point of view. Firstly it has been an analysis of the Pork Chain in order to establish a framework. The objective is to highlight the changes in the sector which have influenced on fattening phase. The result was the necessity of satisfying the consumer demands. In the following chapters a Decision Support was developed based on the consumers requirements. Based on a biological model, a managerial model has been developed to analyse the fattening phase. The decision support system takes into account three alternative pig meat markets: Live body weight pricing, carcass merit pricing, and components or cuts pricing system. Apart from the alternatives markets, its objective is to determine the best marketing strategy for each different genotypes (production alternatives) depending on the market where they will be sent. In addition, the effect of animal variability on economic figures has been studied. Also it has been considered the option of marketing the animals in different stages in order to homogenise the weight of animal sent. This problem has been treated under dynamic programming framework. In near future pig meat markets are going to be more defined, therefore the fattening phase of pork production must take consumer demands into account.

Texto completoA implementação de programas de monitorização de lesões detetadas durante a inspeção post mortem é uma realidade cada vez mais presente nos países da União Europeia. Com estes é possível auxiliar o produtor a conseguir lotes de animais mais saudáveis, promovendo a saúde animal, o seu bem-estar e um melhor desempenho produtivo. Neste trabalho procurou-se estudar a incidência e gravidade de diversos processos patológicos detetados na linha de abate que se encontram normalmente associados a diminuição do desempenho produtivo dos animais ou que podem ser indicadores de problemas de bem-estar animal. Complementarmente, realizou-se uma comunicação mensal dos resultados da inspeção ao médico veterinário das respetivas explorações de origem dos animais. O estudo foi desenvolvido numa amostra de 15894 suínos de engorda, pertencentes a 118 lotes. Cada animal era avaliado quanto à presença de lesões sugestivas de pneumonia enzoótica, pneumonia vírica, pleuropneumonia, abcessos pulmonares, pioémia, pleurisia, pericardite, peritonite, lesões focais de hepatite intersticial crónica (“manchas leitosas”), cicatrizes hepáticas, dermatite papular e lesões na cauda. Os resultados obtidos revelaram que as lesões com localização no sistema respiratório, nomeadamente as lesões sugestivas de pneumonia enzoótica e pleurisia, foram as mais frequentes nas explorações em estudo, tendo sido identificadas praticamente na totalidade dos lotes. No entanto, outras lesões também foram identificadas nos lotes estudados tendo sido bastante elevada a sua frequência, o que confirma o grande impacto negativo que têm tanto no bem-estar animal como na economia das suiniculturas.
ABSTRACT - ANIMAL WELFARE AND POST MORTEM LESIONS IN PIGS - The implementation of lesions recording systems on slaughterhouses is becoming an increasingly common practice in the countries of the European Union. These help the producer to achieve healthier batches, promoting animal health, their welfare and improvements in productivity. The aim of this study was to investigate the incidence and severity of various pathologies detected in slaughtered pigs. These pathologies are usually associated with a reduction in performance traits or are potential indicators of the presence of welfare problems in the herds. In addition, a monthly report with the monitoring results was sent to the herd’s veterinarian. A sample of 15894 fattening pigs belonging to 118 batches was studied. For each animal was recorded the presence of enzootic pneumonia-like lesions, viral-like pneumonia, pleuropneumonia, pulmonary abscesses, pyaemia, pleurisy, pericarditis, peritonitis, chronic focal interstitial hepatitis ("milk spots"), hepatic scarring, papular dermatitis and tail damage. The results obtained suggest that respiratory lesions, such as enzootic pneumonia-like lesions and pleurisy, are the ones that are most present in the farms under study, both of which have been identified in almost every batches. However, other lesions were also frequently identified in batches and showing high prevalence, confirming the great impact that these have on animal welfare as well as on economic level.

Texto completoThe experiment was performed on a total of 90 hybrid pigs divided into experimental groups based on their origin (litter), sex and initial body weight. The pigs were assigned to six experimental groups (15 animals per group): group 1 – animals fed a complete diet and kept freerange, group 2 – animals fed a complete diet and kept indoors in pens with litter bedding, group 3 - animals fed a complete diet and kept indoors in pens without litter bedding, group 4 – animals fed a complete diet and alfalfa forage, kept free-range, group 5 - animals fed a complete diet and alfalfa forage, kept indoors in pens with litter bedding, group 6 - animals fed a complete diet and alfalfa forage, kept indoors in pens without litter bedding. All management systems were animal welfare-friendly. Both at the first and second stage of fattening (approx. 50 kg and 100 kg BW, respectively), the experimental factors had a significant effect on the majority of behavior patterns in pigs. An increase in rest periods and a reduction in locomotor activity and other types of behavior were observed in older animals.

Texto completoApple pomace is a by-product of the industrial production of apple juice, amounting to approximately 20-30% of freshly processed apples. Several million tonnes of apple pomace is produced in the world annually. Fresh apple pomace is characterised by high sugar and moisture content, which makes it susceptible to microbial contamination, uncontrolled fermentation and spoiling. Despite increasingly stricter legal regulations in managing biodegradable waste, large quantities of apple pomace are still being disposed of at landfills, posing a serious environmental issue. Since apple pomace has a certain nutritive value, it seems necessary to consider possibilities for using it as animal feed.
The main goal of this research was to examine the possibility for using dried apple pomace as animal feed, i.e., as a raw material in the industrial production of animal feed. Accordingly, the nutritive value of dried apple pomace was examined, along with the process of pelleting, since pelleting is one of the most common technological procedures in the industrial production of animal feed.
The testing of the chemical composition of dried apple pomace, used to determine its nutritive value, included the analyses of the content of raw proteins, raw fats, raw fibres, ash, neutral detergent fibres (NDF), acid detergent lignin (ADL), lignin, total sugars, individual sugars – fructose, glucose and sucrose, essential amino-acids, vitamins and mineral elements. When compared with the majority of commonly used animal feeds, the dried apple pomace was found to contain large amounts of raw fibres and sugars and small amounts of proteins and fats.
In accordance with the determined nutritional composition of the dried apple pomace, concentrate mixtures for fattening pigs were prepared, after which a trial was performed to examine the effect of feeding the animals on the mixtures containing dried apple pomace in different concentrations on the production performance of the fattening pigs. The results of the feeding trial showed that adding 7% of dried apple pomace in the growing period and 10% in the finishing period had no negative effects on the animal health, production and meat yield.
In the next part of the research, the dried apple pomace was pressed into pellets, with three starting moisture contents in the unpelleted material – 10%, 13% and 16%. The examination of the produced pellets showed that they had very good physical quality in terms of the pellet durability index (PDI) and hardness. The value of PDI exceeded 99% for all three starting moisture contents. The bulk density of the pelleted dried apple pomace was nearly twice as large as it was before pelleting. Increasing the moisture content in the dried apple pomace from 13% to 16% resulted in lower temperatures and energy consumption in the process of pelleting.
The goal of the next part of the research was to examine the effect of adding apple pomace into the concentrate mixture models consisting of corn and sunflower meal on the physical quality of the obtained pellets, the specific electricity consumption of the pellet press and the temperature of the pellet press die. Three concentrate mixture models were prepared for the test, comprising 0%, 10% and 20% of dry apple pomace. The mixtures were conditioned by adding water to reach the moisture content of 13%, 15% and 17% and pelleted at three settings of the press die (8, 24 and 30 mm). Therefore, three parameters were varied at three levels, in a full factorial experimental design. The dependent variables (response variables) were: PDI, pellet hardness (H), dust content in the pellets, bulk density of the pellets, matrix temperature of the pellet press and the specific energy consumption of the pellet press. The results showed that adding dried apple pomace into the model concentrate mixtures led to a significant increase in pellet quality, especially in terms of increasing the PDI value and decreasing the dust content. The results of the analysis of standard scores (SS) showed that the optimum values for pellet quality, specific energy consumption and temperature of the press die were obtained for the model concentrate mixture containing 10% of dried apple pomace, using 30 mm press die and with 17% of the starting moisture content. Good results were also obtained for the model concentrate mixture containing 20% of dried apple pomace, using 24 mm press die and with 17% of the starting moisture content.
To define the effect of the concentration of dried apple pomace in the model mixtures, the press die thickness and the starting moisture content on the change of the response variables, the response surface methodology (RSM) was used. The analysis of variance (ANOVA) of the response models for each of the analysed quality parameters and pelleting processes, showed which of the process parameters (percentage of apple pomace in the concentrate model mixtures, press die thickness and starting moisture content) had statistically the biggest effect on creating the mathematical response models, presented in the form of the second order polynomial (SOP). The results of this research showed that the increase in the percentage of dried apple pomace, press die thickness and starting moisture content led to an increase in PDI value, hardness (H) and bulk density of the pellets and a decrease in the content of dust in the pellets. The increase in the share of apple pomace in the model mixtures and in the die thickness of the pellet press led to an increase in the specific energy consumption and die temperature. On the other hand, the increase in the starting moisture content led to a decrease in the specific energy consumption and die temperature.
In the last part of the research, on the basis of the determined nutritive value of the dried apple pomace the author made a calculation, in terms of optimising the concentrate mixtures containing dried apple pomace in the optimum amount for feeding particular species and categories of farm animals. The results suggest the way of practical utilization of dried apple pomace in feeding farm animals as well as in the industrial production of animal feed.

Texto completoNesta dissertação pretendeu-se identificar potenciais indicadores do bem-estar animal na exploração a partir dos resultados da inspeção post mortem de porcos de engorda no matadouro. Para isso, aplicou-se o protocolo de avaliação de bem-estar do projeto Welfare Quality® a 30 explorações e no matadouro recolheram-se os resultados da inspeção post mortem relativos às explorações visitadas. Outro objetivo foi caracterizar as explorações e as diferenças entre as genéticas produzidas quanto aos resultados da avaliação de bem-estar na exploração e à prevalência de reprovações no matadouro. Das explorações avaliadas, 25 obtiveram classificação “Bom” e 5 obtiveram classificação “Aceitável”. Não houve explorações “Excelentes” ou “Não Classificadas”. O princípio com pior pontuação foi a Boa Saúde (BS), sendo que o critério Ausência de Dor Causada por Procedimentos de Maneio foi o que obteve uma pontuação mais baixa. O princípio BS foi, aparentemente, o que mais influência teve na classificação final das explorações. Não houve diferenças estatisticamente significativas entre a prevalência de reprovações de explorações com classificação “Bom” e “Aceitável”. Porém, foram identificadas algumas correlações entre as variáveis criadas com base nos registos do matadouro e o bem-estar dos animais na exploração. O modelo construído para prever o BEA na exploração a partir das variáveis do matadouro classificou corretamente 60% das explorações. Este modelo não é o ideal mas, dadas as limitações deste estudo, permitiu realçar o potencial da utilização dos dados recolhidos no matadouro.
ABSTRACT - This thesis aimed to identify potential indicators of animal welfare on the farm from post mortem inspection results of fattening pigs at the slaughterhouse. For this, the Welfare Quality® assessment protocol was applied in 30 farms and the data regarding the post-mortem inspection results of the visited farms was collected. Another objective was to characterize the farms and the differences between the breeds produced regarding the results of the welfare evaluation on the farm and the prevalence of condemnations at the slaughterhouse. Of the evaluated farms, 25 were classified as "Good" and 5 as "Acceptable". There were no farms classified as "Excellent" or "Not Classified". The principle with the worst score was the Good Health (GH), and the criteria Absence of Pain induced by Management Procedures was the one with the lowest score. The principle GH was apparently the one which had the most influence in the final classification of farms. There were no statistically significant differences between the prevalence of condemnations of the farms with a “Good” and an “Acceptable” welfare. However, we identified some correlations between the variables created from the slaughterhouse records and the welfare of animals at the farm. The model constructed to predict the BEA on the farm from the slaughterhouse variables classified correctly 60% of the farms. This model is not ideal but, given the limitations of this study, it allowed to highlight the potential of the use of data collected at the slaughterhouse.

Texto completoThe aim of this project was to analyse and evaluate the preference of fattening pigs concerning different floors in the resting area using sensor based identification. The experiment was aimed at contributing to a more objective evaluation of housing systems in pig production. Preferences were identified by letting the animals chose between two lying areas with different flooring (totally slatted floor, partly slatted floor and non-slated floor). The behaviour of 42 pigs was recorded continuously throughout the whole fattening period. Each identifications of pigs by entering or leaving the resting areas or by using the feeders and drinkers was transmitted by the data line to a PC and stored. The individual identification of the pigs was ensured by ear-responders. The basic approach assumes that the preference can be calculated as a function of time via the frequency of visits and duration of stay in accessible resting areas. The results of this study showed high individual variations of these characteristics. This raises the question of the relevance of these two characteristics in the description of the true preference. It is assumed that the pigs do not only visit the resting areas to rest, but also to satisfy their exploration behaviour. It is expected that only the long duration of stays characterize the preferred flooring system. Therefore a method should be developed to classify this kind of visit. The aim of this classification was to use only the resting period (the long visits in the resting area) for further evaluations. The results of this study showed that the characteristics rest duration and frequency of rest periods provides a better basis for the evaluation of preference behaviour. In the context of these investigations, the presented evaluation method was a useful tool to compare differently designed resting areas.
