Wagner, Jennie Faith. "Can Beef Be Bee-Friendly? Using Native Warm-Season Grasses and Wildflowers in Pastures to Conserve Bees." Thesis, Virginia Tech, 2020. http://hdl.handle.net/10919/98621.

Abstract:
Over the past several decades, native and managed bee populations have decreased in the United States and worldwide. Although bee decline is attributable to several factors, habitat loss is the primary driver. Simultaneously, cattle producers in the eastern U.S. rely primarily on cool-season forages that peak in biomass production in late spring, leading to a lack of forage in the summer months and increasing the costs of cattle production. Seeding pastures with a mix of native warm-season grasses and native wildflowers could increase forage availability while also increasing available resources for bees. In this study, a mix of three native warm-season grasses (NWSGs) and 15 wildflower species was planted at the Virginia Tech Shenandoah Valley Agricultural Research and Extension Center (SVAREC). The objectives of this project were to document the establishment and species composition of NWSG + wildflower pasture mixtures, compare the attractiveness of wildflowers and weedy species to bees, and compare the bee community between NWSG + wildflower pastures and more typical cool-season grass pastures. The wildflowers in the NWSG + wildflower pastures dominated over grasses. All wildflower species that established were attractive to bees, as were some weedy species. The NWSG + wildflower treatments had the highest abundance of bees collected, with an average of 14.8 bees collected per pasture per sampling date in 2018, and an average of 12.4 bees collected per pasture per sampling date in 2019. These results indicate that with modification of establishment methods so that more grasses are present, this pasture system could be beneficial from both a cattle production and bee conservation standpoint.
Master of Science in Life Sciences
Over the past several decades, there has been a decline in bee populations in the U.S. and around the world. Bees play an important role in pollinating many food crops, including most fruits and vegetables. Habitat loss is the biggest contributor to their decline. There are also issues with cattle production in the eastern U.S. Most farmers rely on grasses that are the most productive in the late spring and early summer, meaning that by mid- and late summer, there is little grass available for cattle. Planting pastures with native grasses designed to be the most productive in the late summer and native wildflowers could increase food available for cattle as well as provide more pollen and nectar for bees. In this experiment, we planted a mix of three grasses and 15 wildflowers. We documented how well the grasses and wildflowers established. We also examined how attractive wildflowers and weeds were to bees and compared the number and types of bees collected between the new pastures and traditional pastures. We found that the wildflowers, instead of the grasses, dominated the pastures. All wildflowers that established, as well as some weeds, attracted bees and provided resources. Higher numbers of bees were collected in the pastures with wildflowers than standard grass pastures, but there were not necessarily more bee species present. These results suggest that, with some modifications, planting native grasses and wildflowers in pastures could help conserve bees as well as benefit cattle farmers.

Abstract:
Beef constitutes an important part of many consumers’ diets. Beef is the most consumed red meat in South Africa. Consumer perceptions can affect the whole supply or value chain of beef. Recently there has been increased interest in food safety; greater concern for environmental and animal welfare issues, increased importance of eating quality and healthy food as well as the greater role of food services. The demand for beef is no longer limited to economic factors alone but to non-economic factors as well. Consumers of beef in Alice have become more concerned about meat-borne risks and personal health. This research prioritized the exploration of the beef consumers’ (i) self-perception (ii) price perception (iii) benefit perception [in the form of – (a) value perception and (b) quality perception]. The study was conducted in the Eastern Cape Province specifically in Alice town and the surrounding rural areas (Ntselamanzi, Gaga, Hillcrest, Gqumashe, and Dyamala) of the Nkonkobe municipality. Anyone who admitted to eating beef and at the point of data collection bought beef for their own consumption or family consumption was deemed as a unit of analysis. Non – probabilistic sampling techniques which included accidental and random sampling were used to collect data from 100 interviewees. A semi structured questionnaire was used to analyse the perceptions and attitudes of beef consumers. The respondents were asked to indicate their agreement or disagreement with 47 statements or items presented on either five alternatives in a Likert scale scored from 1 (strongly disagree) to 5 (strongly agree) or a six Likert scale ranging from 1 (very low) through 5 (very high) to 6 (I do not know).The data was analysed using SPSS. It was discovered that beef consumers did not consider either intrinsic or extrinsic cues in isolation when purchasing beef but rather all characteristics contribute to the final perception. The Alice consumer market is heterogeneous and consists of different races with different cultures and market segments with varying needs and preferences. The results showed that five factors were extracted from forty seven items Factor 1: Information reliance and quality indication; Factor 2: convenience; Factor 3: Traceability and animal Welfare; Factor 4: Health and safety Conscious and Factor 5: Price and Branding. Furthermore, four main consumer segments emerged as - Segment 1: Informed buyers; Segment 2: Elite buyers; Segment 3: Health & safety conscious buyers and Segment 4: Apathetic buyers. The cluster analysis shows that quality is a subjective concept that is informed by a consumer’s personal taste and preferences. Taste and preferences inform the consumer’s effective demand which in retrospect is informed by the consumer’s socioeconomic status.

Abstract:
Introduction and Aims. The EC is presently in a position of excess food supply and rationalisation has been necessary. Farmers must consider the nature of the demand for specific foods in an effort to secure a share of this market for their output. It is the farmer-producer of beef to whom this study is directed. The research project seeks solutions to some of the problems presently experienced by Scottish beef producers by analysing the market for a system of young suckled bull beef production. The aims of the research are firstly, an assessment of the factors which govern the feasibility of this system in Scotland and, if these are favourable, the formulation of a marketing strategy to aid farmer-producers in its development. Method. The information needed for this analysis was collected by means of a series of six factual and attitudinal market surveys of the participants at each stage in the production and marketing chain for young suckled bull beef, from West Highland crofters producing weaned calves to beef consumers. These surveys are analysed, interpreted and the findings presented. Conclusions. At the rearing and finishing stages any problems were out-weighed by the advantages of more efficient growth and improved carcass quality. But, although abattoirs handling young bulls had experienced no economically significant problems and retailers acknowledged the superiority of young suckled bull beef carcasses, there is a widely-held belief that the eating quality of all bull beef is less acceptable to consumers. A consumer panel test of this belief was invalidated because the beef supplied was not as ordered. There is a need to improve the scope and flow of information on the nature of cattle killed. In the short term at least there is a market for this product. And if young suckled bull beef can be promoted effectively development of this sector will occur. Several areas can be identified which are essential to a marketing strategy for young suckled bull beef producers. It is vital to ensure repeatability and uniformity of breeds, age, weight and post-slaughter treatment of carcasses. A joint venture with some measure of integration is strongly recommended. A scheme of producers guidelines is also recommended. Farmer-producer groups should establish links with an abattoir-wholesaler of beef. A link should also be established with the multiple retail sector. And promotion of the product could be via this sector into a specific market segment and should focus on quality aspects and health and welfare concerns.

The U.S. beef industry is comprised of multiple, vertically connected segments. Beginning at the cow-calf level, cattle move through the industry to backgrounding/stocker operations, feedlots, and then to beef packers. The beef produced then continues to move through the marketing channel from beef packers to wholesalers and on to multiple final consumer outlets. Each level of the beef industry has both distinct and related economic issues. This dissertation contains three essays on beef cattle economics. Essay 1 focuses on price and animal health risk management at the feedlot level. Essays 2 and 3 explore how upstream demand changes impact primary beef suppliers. The objective of Essay 1 is to determine if feedlot operators manage price risk and animal health risk as two separate and independent risks or if they manage them jointly. The animal health attribute of interest is purchasing feeder steers from a single known source versus an auction with unknown background. The output price risk mitigation tools are futures contracts, forward contracts, other, and accept cash price at time of sale. Primary data is collected using an online survey administered to feedlot operators. Participants are placed in forward looking, decision making scenarios utilizing a split-sample block design. Evidence of a relationship between animal health risk and output price risk management is mixed. Ricardian rent theory (RRT) is tested in Essay 2 to determine if complete pass-through occurs from fed cattle and corn prices to feeder cattle prices. Monthly price data from December 1995 to December 2016 is used. Based on RRT, surplus rents should pass through the market to the holder of the scarcest resource. In cattle markets, feeder calves are the scarcest, widely traded resource and thus gains and losses at the feedlot theoretically pass-through to feeder cattle prices. The hypothesized pass-through rates suggested by RRT is calculated using monthly production data from the Focus on Feedlots data series. The regression pass-through estimates are tested against the hypothesized RRT pass-through. In many models, the estimated pass-through rate is statistically greater than the RRT hypothesized pass-through rate. Thus, when fed cattle or corn prices change, these changes are more than fully passed to cow-calf producers through the feeder cattle price. Evidence is found of asymmetric pass-through during times of herd expansion versus contraction. Essay 3 provides a quantification of how changes in retail and export beef demand are transmitted to different members of the beef industry. Understanding how information is transmitted from primary consumer demand through the supply chain is key for long-term prosperity of the U.S. cattle industry. However, empirical applications quantifying how demand signals are transmitted through vertically connected industries are limited. Using both naïve and forward looking price expectations, a four equation system of inverse demand and supply equations for live and feeder cattle is estimated. Using retail and export beef demand indices, the impacts of 1% change in retail or export demand on live cattle and feeder cattle prices are quantified.

Sachse Family Angus is both a commercial and registered Angus cow-calf operation in Northeast Kansas and has been in operation since 1935. The end goal in mind is to provide quality female breeding seedstock to other beef producers with the hopes of improving their herds. Successful selection and development of beef replacement heifers have major long term effects on stayability in any herd and can even have a positive impact on the whole herd. The objective of this study is to create a decision tool to determine best heifer selection strategies. Specifically, taking a look at the cost of heifer development under a range of scenarios as it applies to more traditional heifer development. The depth of literature addressing the issue of buying or raising replacement heifers is vast, providing various degrees of analysis to help a producer make the best informed decision. Some economists would argue that no single aspect of beef production management is as complicated, or has such an economic impact as cow culling and replacement heifer decisions (Melton, 1980). Procedures and methods were created to analyze whether a producer should raise or develop their own replacement heifers. One method used in creating a decision tool is an enterprise budget. Enterprise budgeting is the systematic determination and listing of expected outputs, revenues, and costs due to the production processes required to produce one unit of an enterprise for a specified time period. To take this one step further, it is assumed a producer makes choices with respect to the combinations of productive factors and products. Partial budgets include an analysis of net returns from small changes or refinement to a ranch. It focuses on parts that change while building upon an enterprise budget. In essence, it fine tunes current operations while holding all else constant. The benefits of partial budgeting take a look at what will be the new or added revenue if a change is implemented on the ranch and what costs will be reduced or eliminated if taken place. What will be the new or added costs and what revenues will be reduced if a change takes place are also things to keep in mind. Therefore, the result will show a producer the net benefit of the change. In turn, Sachse Family Angus will use this information to build their registered and commercial replacement heifers either by developing their own or purchasing from other breeders. Overtime, this decision will be critical as it will impact their herd for years to come. In conclusion, maintaining a good sound, high functioning beef cow herd means selecting and developing quality replacement heifers to retain in the herd each year. An estimated 20% of heifers born each year at Sachse Family Angus are kept as replacement heifers. When managing home raised heifers or purchased heifers, maintaining costs and keeping them in check is crucial because they represent a large up-front investment. The bottom line of this research is to give the managers at Sachse Family Angus and other operations across the country a decision tool that can be used to analyze their current resources and the resources it will take to develop their own heifers successfully and in the most cost effective way or help them analyze if purchasing their heifers makes the most financial sense.

Abstract:
This dissertation includes three essays on U.S. beef market. Each essay has looked at this market from a different point of view. The first essay investigates the price adjustment along the different levels of this market. The second essay discusses the impact of food safety incidents on export levels in this market. The third essay considers the environmental loading of U.S. beef market. A summary of each article is as follows. The first essay (chapter 2) analyzes price adjustment of the U.S. beef sector with a focus on the Great Recession. To this purpose, the Vector Error Correction Model (VECM) and historical decomposition graphs are applied to monthly data. The results indicate that retail prices have lower speeds of adjustment than wholesale prices. Also, the magnitude of price adjustment in the presence of the Great Recession, as an exogenous shock, is different for each level of the U.S. beef market. It is concluded that, with respect to both the speed and magnitude of the price adjustment, the U.S. beef sector has an asymmetric price adjustment, pointing to the inefficiency of the U.S. beef supply chain. These results have welfare implications for U.S. beef consumers and producers. The primary objective of the second essay (chapter 3) is to quantify the impact of consumer awareness about beef safety on U.S. beef exports. To do that, an index is used to reflect consumer’s awareness about beef safety based on the publicized reports in the media. Quarterly panel data is applied to the top importing countries, Japan, South Korea, Mexico, and Canada for the period 2000-2016. Applying the gravity model, results show that a 0.8% reduction in U.S. beef exports arose from the foodborne-disease news. In addition, using impulse response functions derived from panel vector autoregressive (Panel VAR) estimation, results show that the negative impact of a shock in food safety news intensified after three quarters, and then diminished slowly over time. In order to regain consumers’ confidence and to compensate for the economic loss arising from a foodborne outbreak, bilateral cooperation among trade partners seems necessary. Investing in any scheme that minimizes the impact of food safety events, such as disease eradication programs, traceability systems, quality labeling, and third-party certification that conveys the safety message to consumers is suggested. The third essay (chapter 4) has two purposes. First, it quantifies the environmental loading of U.S. beef sector by calculating emission levels over the period 1970-2014. Beef cattle is one of the most emission-intensive sectors, which is responsible for 35% to 54% of total GHGs from livestock. Following International Panel on Climate Change (IPCC) guideline, this study identifies three sources of emissions, including enteric fermentation, manure management, and manure left on pastures. Second, it provides an understanding of consumption-environmental connection related to the beef industry using time series techniques. Finally, it is suggested that providing information to the public regarding livestock and climate change relationship would be beneficial. This knowledge might help to avoid the catastrophic consequences of climate change in the future.

Abstract:
Thesis (M.Sc. (Agricultural economics)) --University of Limpopo, 2011
The cattle (especially beef) industry in Botswana has traditionally played an important role in the country’s economy, with significant contributions to Gross Domestic Product (GDP), exports, and employment, as well as playing an important role in social and cultural spheres. Agriculture contributes about 2.3 % of GDP, out of which 70% - 80% is attributable to cattle production. By 2004, beef exports amounted to P284m, approximately 1.7% of total exports of P16.2 billion. In recent years, however, there have been signs of decline and stagnation, especially in the beef export subsector, with adverse implications for the viability of cattle farming in the country, and more generally for rural livelihoods. Botswana’s beef subsector has not fulfilled its potential as a contributor to economic growth and development, especially in the rural areas. The BMC has never been able to meet its quota of 19 000 tonnes of beef to the European Union (EU), despite being cushioned by the Continuo agreement against price competition from more efficient beef producers like Brazil. With the above background, the study was undertaken to examine the supply response of beef farmers in Botswana to various economic (e.g. prices) and non-economic [e.g. rainfall, technology and inventory (cattle population)] factors. This study used historical data on Botswana’s beef subsector for the period 1993 to 2005, and Nerlove’s partial adjustment model was used for the empirical analysis of the data. The results of the study revealed that Botswana beef farmers respond positively to price incentives and time trend (proxy for technology), and negatively to all other variables. Elasticities of supply showed that cattle supply is elastic with respect to variations in producer price and almost unit elastic to changes in cattle inventory. However, the response to shocks in other variables included in the model was inelastic. Short run price elasticity of supply is 1.511 whereas long run price elasticity is 10.57, a clear sign that pricing can be employed as a strategy to enhance beef production in Botswana. The speed of adjustment however, was relatively very low at 14% per period. This slow adjustment perhaps tells us that Botswana farmers, who are predominantly subsistence farmers, may not be having enough capacity (in terms of resources and technology) to immediately increase production when economic environment improves in their favour. Based on the results it is recommended that price increase be adopted as a strategy for improving cattle supply. Extension services need to be strengthened with a view of promoting cattle farming as a commercial activity. Current technology of using communal grazing and indigenous breeds need to be improved. It is also recommended that studies be conducted to determine the suitability of technology that is at the disposal of the farmers. Lastly Botswana government needs to come up with a strategy by which farmers can change from their attitude of oxen production to weaner production.

Abstract:
An assortment of 1,551 retail cuts were purchased from eleven cities across the United States to study their physical and chemical composition. Information with regard to external fat thickness, package weight, price per kilogram, and total package price were collected at the retail store. Cuts were purchased and later dissected into four different separable components, separable lean, external fat (carcass and cut), seam (intermuscular) fat, and bone and heavy connective tissue. Chemical fat analyses were conducted on the separable lean component of each dissected cut. Dissection data showed that cuts originating from the round had the highest means for separable lean percentages, resulting in the lowest means for separable fat percentages. Cuts from the rib were found to have the highest separable fat percentage means, thus the lowest separable lean percentage means. Chemical fat data mirrored dissection data, with round cuts having the lowest means for percent extractable fat for the separable lean (only) and rib cuts producing the highest means. In general, ground beef packages had a lower percentage of extractable fat than the fat percentage that was declared on the retail package label. This study was designed to acquire data on cuts presently available at the retail level and compare their composition to data presented in the National Nutrient Database for Standard Reference. It must be noted that separable fat percentages are not available for many of cuts sampled for this survey. Additionally, data reported in the Nutrient Database encompasses only retail cuts trimmed to 1.25 cm, 0.6 cm, 0.3 cm, and 0.0 cm. Cuts from this study consistently had fat thickness measurements between 0.0 cm and 0.3 cm; thus, there is no nutritional information in the Nutrient Database for beef cuts trimmed to these levels.

The cattle market has drastically changed over the last half century. Today, ranchers and farmers are faced with various governmental regulations as well as fluctuating grain and fuel prices. While beef may still be a commodity, it can be sold in specialized markets, in markets that have enhanced consumer demand. It is nearly impossible for a producer with a small herd to compete with a larger ranch if they are selling their cattle as a commodity. The primary economic objective of the producer is to generate revenue. Producers must be profitable to remain in business as well as provide a livelihood for their family. Providing a quality product is part of the business model. Choice within a marketplace is beneficial for producers and consumers. That said forage-fed beef will prosper in marketplaces where consumers desire their product more than alternate products. If producers are intent on progressively growing their market share, Georgia-grown, forage-fed beef must be marketed correctly. This includes promoting it on a basis of locally grown, pasture raised, and other attributes consumer’s desire. The results of the marketing survey present data that may be helpful when marketing Georgia-grown, forage-fed beef. The weekly consumption of beef products provided insight into the potential scope of the market. Approximately 39 percent of respondents consumed beef products three or more times per week. Additionally, 43 percent of the respondents were not familiar with forage-fed beef. This is a significant share of the market that is possibly open to a new product like Georgia-grown, forage-fed beef. Similarly, traceability of the product was an important feature that customers preferred. In addition to a larger selection of naturally produced beef products, respondents also indicated they were willing to pay more for the product. Approximately 49 percent of the respondents indicated that they would be willing to pay up to a dollar more per pound for Georgia-grown, forage-fed beef. Another 30 percent of the respondents indicated that they would be willing to pay more than $1 per pound for Georgia-grown, forage-fed beef. The results of the survey appear to offer opportunities for producers of Georgia-grown, forage-fed beef to expand their market share.

Abstract:
Variability in beef eating quality is seen as a major causative factor for the decline in beef consumption and value in Europe. Consumers have difficulty selecting beef of appropriate eating quality using price, visual appearance, and other information provided at the point of sale. With eating quality the biggest factor which influences a consumer’s decision to buy a product again, the future of the meat industry depends on the delivery of beef with a consistent and reliable eating quality. At present the Australian beef industry uses a revolutionary eating quality based grading system called MSA (Meat Standards Australia) to deliver an ‘eating quality guarantee’ to the consumer and financial incentives to producers to improve eating quality. This PhD investigated the suitability of a similarly constructed system for the European beef industry. The European market currently trades beef carcasses based on the European carcass grading system. This system uses visual assessment processes to give a score for both muscling and fatness and is legally required for the purposes of price reporting. Its strong presence in the market has greatly influenced the development of the European beef industry, encouraging the production of heavily muscled, high yielding carcasses with moderate fat cover. In this thesis we have investigated any relationship between this system and eating quality, to determine both the effect of selection based on this system on eating quality and the potential usefulness in an eating quality based grading system. Through the grading and taste-testing of over 300 carcasses it was found that there was no substantial relationship between the European carcass grading system and eating quality. Therefore selection based on this system would not negatively impact eating quality, and the system could operate in parallel with an eating quality based grading system. Entire male beef carcasses, bulls, are also important in the European beef industry due to their increased growth rates and higher yielding carcasses. In contrast, bulls are not an important part of Australian beef production and they are currently ineligible for grading in the Australian MSA system, though there are plans for their inclusion in the future. Additionally dairy breeds are often used for beef in Europe, due to the importance of the dairy industry. It is well known that sex and breed (beef v/s dairy) affects many aspects of a carcass which influence eating quality, such as intramuscular fat, carcass weight, yield, muscle fibre type, etc. This meant that for the development of a European eating quality based beef grading system it was important to determine if there was a sex effect on eating quality. From the results of this thesis it was found that carcass measurements used in the MSA system were unable to completely explain the differences in eating quality between the breeds and sexes, and a separate adjustment for bulls and dairy breeds was required for an eating quality grading system. Additionally, the differences between the sexes varied between muscles, highlighting the need for further work on some of the muscles with limited testing. The European and Australian industries also vary in their estimation of animal maturity. As an animal matures there are age related decreases in eating quality, mostly associated with collagen crosslinking and some fibre type shifting. Australia, and the MSA system estimates this through a measure of bone maturity called ‘ossification’. The rate of ossification is influenced by the hormonal state of an animal, for example pregnancy, lactation, castration and the use of hormonal growth promotants. In contrast the European beef industry takes advantage of the accurate age records that are required for all production animals. The relationship of these two measures to maturity related decreases in eating quality is outlined in this thesis. Ossification score is a more appropriate measure for young animals, most likely due to its relationship with the hormonal state of the animal. However, as animals mature and reach the maximum ossification scores this measure loses sensitivity and animal age becomes more appropriate. Therefore a combination of both measures should be used in the grading of eating quality in Europe to fully encompass the diversity present in the industry. Emerging technologies will make new testing and grading procedures possible in abattoirs. Biochemical attributes of beef have been shown to be related to eating quality, and have been tested using objective measures and trained consumer taste panels. However, they have never been tested with untrained consumers. The relationship between untrained consumer scores for beef and intramuscular fat, moisture content, heme iron content, and total, soluble and insoluble collagen is also explored in this thesis. Biochemical attributes explained the majority of the variation in consumer scores across different muscles, but not within individual muscles. Therefore the results from consumer analysis can be extrapolated to muscles with similar biochemical attributes; however biochemical testing would not add value to a commercial eating quality grading system. The actual eating quality experienced by the consumer must match the designated quality grade for eating quality based grading system to achieve its aims of improving customer satisfaction and encouraging the production of quality beef. After exploring carcass and animal traits that influence eating quality, this thesis focuses on consumers and their ability to quantify beef eating quality. In particular it is concluded that there are no major demographic effects on consumer evaluation of eating quality, and willingness to pay. The relative importance of different sensory attributes to consumers is investigated with the conclusion that these are also remarkably consistent between diverse cultural groups. These results demonstrate that a beef eating quality grading system, similar in design to the Australian MSA system, is highly applicable to both the European beef industry and the European consumer. Currently only small scale certification systems and branded products offer the European consumer any information on the expected eating quality of beef. A universal, European eating quality based grading system would improve the industry by simultaneously encouraging the production of high quality beef and providing a better and more consistent eating experience to the consumer. This would also increase the value of European beef, allowing the industry to command price increases of up to 200% for premium quality beef. Further work needs to be performed to exactly quantify the statistical model necessary for such a system.

Abstract:
This study analyzes the change in whole-farm net revenues and nutrient reduction from the implementation of five best management practices (BMPs) on a typical beef and beef-poultry farm in Shenandoah County. Whole-farm net revenues, resource allocation, nutrient loss reductions, and the cost efficiency of reducing nutrient losses were analyzed to assess which BMPs are the most cost efficient to implement, assuming the baseline scenarios have no voluntarily applied BMPs. The effects of stacking additional BMPs, in combinations of two or more, were also assessed. No-till cropping, winter wheat cover crop, herbaceous riparian buffer, fencing, and P-based NMP were the BMPs that were analyzed. Incentive payments from state and federal governments were incorporated into the cost of BMP adoption. A brief analysis of a farmerâ s time value of money, with respect to incentive payments, was also conducted. Results indicated that no-till crop management was the most cost efficient BMP, and was the only BMP to increase net revenues for both farm models. Fencing and P-based NMP were the least cost efficient for the beef farm. For the beef-poultry farm, fencing was the least cost efficient. The implications of this study are that farmers that choose to adopt BMP should evaluate both their interests in maintaining (or increasing) farm net revenues along with their interest in improving water quality through the reduction of nutrient losses. There is potential for implementing multiple BMPs, while increasing net revenues from a farmâ s baseline scenario. For farmers and policy makers, no-till cropping can be a profitable and therefore cost efficient BMP to implement. Incentive payments are intended to encourage the adoption of BMPs by subsidizing a portion of the start-up costs. Policy makers should attempt to make cost-share payments reflect nutrient reduction goals. This can be done by analyzing both the compliance cost to farmers and the nutrient reduction effectiveness of BMPs.

Dissertação de Mestrado em Segurança Alimentar
Some physic-chemical properties and lipid profile of beef from two origins (Holland and Spain) were compared with beef from national production of both dairy and crossbred beef backgrounds. In comparison, we can find four different groups: two groups of animals from Spain and Holland; n=10 animals per group) and two groups from national production (dairy and beef production systems; n=10 for animals per origin). Animals used in the study were all males of 8-12 months old. In study we can find two different genetics, the Holstein breed (Holland, Spain and Portugal) and crossbred beef genetics (Portugal). Beef samples were obtained from sirloin (longissimus lumborum) in all groups. The fatty acid profile was determinated by GC. Total cholesterol, -carotene and tocochromanols were quantified by HPLC. The results of comparison showed that beef from crossbred beef bulls was leaner and displayed a distinct fatty acid profile with lower SFA, MUFA contents and higher PUFA and n-3 PUFA contents than beef from Holstein bulls. Beef from the crossbred beef bulls was the only group in total agreement with P/S and n6/n3 ratios. Relatively to beef color parameters, Portuguese beef presented the highest L* and lowest a* values and intermediary b* values. Beef from Holstein bulls raised in Portugal was on the limit of DFD while beef from the Spanish Holstein bulls was a well-established DFD. It is however important to highlight that the study was done with a restrict number of samples, and for this reason it is not possible to conclude that beef from national production has a superior quality than beef from abroad.
RESUMO - Comparação do perfil lipídico e algumas características físico-químicas de carne de bovino proveniente da Espanha e Holanda com carne de bovino nacional proveniente de animais com genética diferente (leite e cruzados de carne) - Este estudo procurou comparar o perfil lipídico e algumas propriedades físico-químicas da carne de bovino holandesa e espanhola com carne de bovino da produção nacional proveniente de animais com genética diferente (leite e cruzados de carne). Em comparação podemos encontrar quatro grupos diferentes. Se tivermos em consideração a genética dos animais, podemos encontrar 2 grupos: 1) animais de genética Holstein (acabados em Portugal, Espanha e Holanda) e 2) cruzados de carne de produção nacional. Se tivermos em consideração a origem, podemos também encontrar 2 grupos: 1) do exterior (Espanha e Holanda) e produção nacional (Holstein e cruzados de carne). O estudo contemplou apenas a utilização de touros do sexo masculino e com uma idade ao abate entre os 8 e os 12 meses de idade (vitelão), tendo-se usado 10 animais por grupo. As amostras de carne usadas no estudo foram obtidas da vazia (longissimus lumborum). O perfil de ácidos gordos foi analisado por GC, enquanto a quantificação dos teores de colesterol total, -caroteno e tococromanóis foi realizado por HPLC. Os resultados do estudo revelaram que a carne proveniente de bovinos cruzados de carne era mais magra e apresentava um perfil lipídico com menor teor de SFA e MUFA e um teor superior de PUFA e n-3 PUFA comparativamente com os bovinos de raça Holstein. A carne proveniente de bovinos cruzados de carne foi a única a apresentar os rácios P/S e n6/n3 em total concordância com as recomendações internacionais. Relativamente aos parâmetros de cor estudados, podemos afirmar que a carne produzida em Portugal apresentou valores de L* mais elevados, e os valores de a* mais baixos do que a carne espanhola e holandesa, tendo apresentado valores de b*intermédios aos obtidos na carne do exterior. O pH da carne de touros criados em Portugal estava no limite da carne DFD, enquanto o pH da carne proveniente de Espanha se podia considerar uma carne DFD. Apesar dos resultados aqui apresentados, é importante realçar que o estudo foi realizado com um número restrito de amostras e que por essa razão não é possível concluir que a carne de bovino produzida em Portugal seja superior à carne de bovino produzida no exterior.
