The size of our dairy operation increased from 300 milk cows to 1,700 milk cows in 2003. Once the dairy operation increased, the dependency on milk price to support the entire operation also increased. This was due to the fact that the cropping side of the operation became more devoted to growing feed for the livestock as opposed to producing cash crops. Thus, the increase in the number of milk cows led to decreased diversity in our income potentially increasing the financial risk of the operation. The purpose of this thesis is to study different risk management tools and strategies to aid in the formulation of a risk management plan for milk sales in our operation. Risk management strategies using forward contracts, futures, put options, and cash were analyzed at different time periods and various minimum price levels. The strategies were analyzed over the last ten years (2001-2010) of available price data. Twenty-five risk management strategies were analyzed both with and without set minimum milk prices. Minimum price levels ranged from $14/cwt to $17/cwt in $1 increments. The time frame for the transaction ranged from zero to twelve months prior to production in three-month increments. Based on historical data, risk management strategies can be used to decrease the price risk faced by an operation. The risk management strategies did not affect the average price received at statistically significant levels typically considered. Different risk management opportunities are highlighted that need to be analyzed before fully implementing a risk management plan for dairy operations.

Dairy Farmers of America (DFA) is national milk marketing cooperative. DFA’s primary focus is to market the milk of the cooperative’s 17,000 members. In addition, DFA offers its membership a number of farm services. The sole purpose of these services is to make it easier for DFA members to operate their businesses. One of the services offered provides members access to forward contracting alternatives for pricing their milk. The objective of this research is to utilize demographic and other information related to the characteristics of individual dairy producers and determine how these characteristics impact the use (or lack thereof) of risk management marketing tools. More specifically, the focus of this research is to identify what types of dairy producers are most likely to use the DFA’s forward contracting program. The logit model estimated indicated that regional and demographic differences impact the use of DFA’s forward contracting program. Members in the Mountain Area are most likely to use the program followed by members in the Central Area. Demographic differences that significantly impacted the use of forward contracting include age (older producers use forward contracts less than younger operators) and the size of operation, as measured by milk produced per year (larger operators were more likely to use forward contracting services). While the estimated logit model did identify several factors related to the use of forward contracting services, relationships are not particularly strong and the percent of producers using the services is relatively low. Thus, the model is limited in its ability for identifying key factors and thus it will be difficult for DFA to base a targeted marketing effort at certain producers. DFA would need additional information about their members to successfully target for this farm service.

Full textThis thesis deals with the use of Geographic Information Systems (GIS) in the transport
of raw fluid milk from its origin on the farm to the processing plant. Current applications of
GIS in transportation planning are discussed. Spatial, physical, administrative and legal
constraints affecting the shipment of fluid milk are outlined, especially the roles of government
legislation and dairy cooperatives. GIS is used to evaluate milk hauling efficiencies on both
local and regional scales. The case study focuses on Rockingham and Augusta counties in
northwestern Virginia and the surrounding hinterland. On the local scale GIS network functions
are used to determine optima] routes for milk trucks between dairy farms in these counties and
the processing plant in Mt. Crawford, Virginia. Comparisons are made between the results
achieved by GIS and the results obtained through traditional methods of route planning. A
regional scale case study uses GIS allocation functions to evaluate the effect of government
regulations (Federal and State Order Markets) on the efficiency of hauling fluid milk from farms
in the study area to plants outside the region. Results indicate that government regulations and
cooperative decisions shape the morphology of fluid milk shipment and that GIS is a useful tool
for regional milk marketing. Finally, a mail survey assesses the present use of automated
systems and GIS among dairy cooperatives, and the possibility of future implementation of such
systems in the dairy industry.

Full textCon el objetivo de obtener nuevos conocimientos sobre la base molecular de la lactación en cabras de la raza Murciano-Granadina (MUG), se llevó a cabo un análisis RNA-Seq de muestras de la glándula mamaria (N=7) obtenidas en tres puntos temporales distintos, es decir, 78 días (T1, lactación temprana), 216 días (T2, lactación tardía) y 285 días (T3, período seco) después del parto. Este experimento permitió identificar 1654 genes expresados diferencialmente (DE), cuyas funciones estaban relacionadas principalmente con el metabolismo de las proteínas, lípidos y carbohidratos, homeostasis del calcio, muerte celular programada, remodelación tisular e inmunidad. Con la finalidad de contribuir a dilucidar la arquitectura genómica de la producción y la composición de la leche, realizamos un estudio de asociación del genoma completo (GWAS) que incluyó 822 cabras con registros para siete fenotipos lecheros medidos durante la 1ª lactación. Este estudio permitió detectar 24 quantitative trait loci (QTL). No obstante, sólo tres QTL mostraron significación estadística a nivel genómico, es decir, QTL1 (cromosoma 2, 130,72-131,01 Mb) para el porcentaje de lactosa de la leche, QTL6 (cromosoma 6, 78,90-93,48) Mb) para el porcentaje de proteína y QTL17 (cromosoma 17, 11.20 Mb) para los porcentajes de proteína y materia seca. Mediante el análisis del patrón de segregación de polimorfismos nucleotídicos sencillos (SNP) de los genes de las caseínas en bezoares (ancestro de la cabra doméstica) y cabras domésticas de Europa, África, Cercano Oriente y Lejano Oriente, se determinó que del 36,1% (CSN2) al 55,1% (CSN1S2) de los SNPs son compartidos por el bezoar y la cabra doméstica. Asimismo, más del 50% de los SNP de los genes de las caseínas fueron compartidos por 2 o más poblaciones de cabra doméstica ubicadas en diferentes continentes, y del 18 al 44% de los SNP fueron compartidos por las cuatro poblaciones domésticas mencionadas anteriormente. Estos resultados nos permiten concluir que una parte importante de la diversidad existente en los genes de las caseínas caprinas emergió antes de la domesticación de las cabras. Otro objetivo de la Tesis consistió en caracterizar la variación del número de copias (CNV) en una población de 1036 cabras MUG. Mediante el uso del software PennCNV y QuantiSNP, identificamos 4617 y 7750 CNV autosómicos, respectivamente, que posteriormente fueron ensamblados en 486 regiones CNV o CNVR. Los genes que mapean dentro de CNVR muestran un enriquecimiento de funciones relacionadas con la transducción olfativa, los transportadores ABC y el desarrollo embrionario. Uno de los CNVR identificados en nuestro estudio coincide con la posición del gen de la proteína de señalización agouti (ASIP), que favorece la síntesis de feomelanina amarilla/roja. En diversos estudios, el aumento del número de copias del gen ASIP fue asociado con un patrón de pigmentación blanco en cabras. Sin embargo, al realizar un experimento de qPCR con el objetivo de cuantificar el número de copias del gen ASIP en poblaciones de cabras con diferentes patrones de pigmentación, averiguamos que el CNV del gen ASIP no sólo segrega en cabras Saanen (blancas), sino también en cabras MUG (negras/marrones) y cabras Malagueñas (rojas/rubias). Este resultado indica la ausencia de una relación simple y lineal entre el número de copias del gen ASIP caprino y la dilución del patrón de pigmentación. Finalmente, hemos investigado la arquitectura genómica de la coloración de la capa en cabras MUG mediante la combinación de distintas técnicas experimentales. Este análisis reveló la existencia de una estrecha asociación entre una mutación aminoacídica (c.801C> G, p.Cys267Trp) en el gen del receptor de la melanocortina 1 (MC1R) y el color negro/marrón de las cabras MUG, lo que implica que la herencia de la pigmentación en dicha raza es monogénico.
In order to obtain new insights into the molecular basis of lactation in Murciano-Granadina (MUG) goats, we carried out a RNA-Seq analysis of mammary gland samples (N = 7) obtained in three different time points, that is, 78 days (T1, early lactation), 216 days (T2, late lactation) and 285 days (T3, dry period) after parturition. This experiment allowed the identification of 1654 differentially expressed (DE) genes, the functions of which were mainly related to protein, lipid and carbohydrate metabolism, calcium homeostasis, programmed cell death, tissue remodeling and immunity. In order to help elucidate the genomic architecture of milk production and composition, we also carried out a genome-wide association study (GWAS) including 822 goats with records for seven dairy phenotypes measured during the first lactation. This study allowed the detection of 24 quantitative trait loci (QTL). However, only three QTL showed statistical significance at the genome-wide level, that is, QTL1 (chromosome 2, 130.72-131.01 Mb) for the percentage of lactose in milk, QTL6 (chromosome 6, 78.90-93, 48) Mb) for the percentage of protein and QTL17 (chromosome 17, 11.20 Mb) for the percentages of protein and dry matter. By analyzing the segregation patterns of single nucleotide polymorphisms (SNPs) mapping to the casein genes in bezoars (ancestor of the domestic goat) and domestic goats of Europe, Africa, the Near East and the Far East, it was determined that about 36.1% (CSN2) to 55.1% (CSN1S2) of casein SNPs are shared between bezoars and domestic goats. Besides, more than 50% of the SNPs of the casein genes were shared by 2 or more domestic goat populations located on different continents, and 18 to 44% of the SNPs were shared by the four previously mentioned domestic populations. These results allow us to conclude that an important part of the diversity existing in the caprine casein genes emerged before the domestication of goats. Another objective of the Thesis consisted of characterizing copy number variation (CNV) in a population of 1036 MUG goats. Using the PennCNV and QuantiSNP software, we identified 4617 and 7750 autosomal CNVs, respectively, which were subsequently assembled into 486 CNV regions (CNVR). Genes located within CNV show an enrichment of functions related to olfactory transduction, ABC transporters and embryonic development. Interestingly, one of the CNVR identified in our study coincides with the position of the agouti signaling protein (ASIP) gene, which favors the synthesis of yellow/red pheomelanin. In several studies, increased copy number of the ASIP gene was associated with a white pigmentation in goats. However, when conducting a qPCR experiment with the objective of quantifying the number of copies of the ASIP gene in goat populations with different coat colors, we found that the ASIP CNV not only segregates in Saanen (white) goats, but also in MUG (black/brown) and Malagueñas goats (brown/blond). This result indicates the absence of a simple and linear relationship between the number of copies of the goat ASIP gene and the dilution of pigmentation. Finally, we have investigated the genomic architecture of coat color in MUG goats by combining different experimental techniques. This analysis revealed the existence of a close association between a missense mutation (c.801C>G, p.Cys267Trp) in the melanocortin receptor 1 (MC1R) gene and the black/brown color of MUG goats, which implies that the inheritance of pigmentation in this breed is monogenic.

This study reviewed state-of-the-art cattle enteric methane (CH4) emissions with three reported measuring units: g/head/d, g/kg DMI (dry matter intake), and %GEI (gross energy intake). Cattle emissions studies included in this meta-analysis were reported from 1995 to 2013. Fifty-five published studies were analyzed with specific objectives: (1) to gain basic information regarding magnitudes and distributions of enteric CH4 emission rates with various units, regions, cattle types and feed situations; (2) to identify and evaluate effects of influence factors or diet mitigation techniques on enteric CH4 emissions; and (3) to evaluate Intergovernmental Panel on Climate Change (IPCC) approaches to estimate enteric CH4 emissions. Emissions data (n=165) with the unit of g/head/d had large variances and non-normal distribution, and were not homogeneous across the studies. Emissions data (n=134) with the unit of g/kg DMI were not homogeneous across the studies, while emissions data (n=76) with the unit of %GEI had small variances and normal distribution, and were homogeneous across the studies. Therefore, data with the unit of %GEI may be better for meta-analysis compared to data with the units of g/head/d and g/kg DMI; however, the number of data with the unit of %GEI was small relative to the number of data with the units of g/head/d and g/kg DMI. Enteric CH4 emissions with the unit of g/head/d are significantly influenced by geographic region, cattle classification, sub-classification, humidity, temperature, body weight, and feed intake. Emissions and feed intake had a strong positive linear relationship with R2 of 0.75 (n=148). Emissions with the unit of g/kg DMI are significantly affected by humidity, body weight, and feed intake. The relationship between emissions and feed intake is positive. Emissions with the unit of %GEI are significantly associated with humidity, production stage, and body weight. IPCC Tier 1 and Tier 2 estimated emissions were approximate to most of the measured enteric CH4 emissions; however, the residuals were not normally distributed. Based on results from PRD method and paired t-tests, IPCC Tier 1 overestimated emissions in Asian studies, underestimated emissions in European studies for beef cattle, and underestimated emissions in Oceanian studies for dairy cattle. IPCC Tier 2 underestimated emissions in Asian studies for beef cattle. The underestimated emissions of IPCC Tier 2 in Asian studies might result from no consideration of effects from production stage and body weight.

Dairy calves are born with an under-developed stomach. The stomach has four compartments: the rumen, reticulum, omasum, and abomasum. The rumen is the largest component where finger-like projections called papillae grow to absorb nutrients for the calf. It is vital to the calf that the rumen develops not only the papillae to absorb nutrients but also to foster a microbe-rich environment so the microbes can act as a defense mechanism for the calf to aid in fighting disease. While it is known that things like solid feed support the development of the rumen, the mechanism behind how that is happening still remains unclear in the literature. The objective of this study was first to better understand the relationships that exist in the literature between dietary, environmental, and ruminal factors, and second to investigate the claim that certain components of the bacteria in the rumen are stimulating rumen development independently and additively with sodium butyrate. In order to investigate the relationships amongst the dietary, environmental, and ruminal parameters, a computer program called R Studio was used to analyze over 30 different models that extracted data from a database that included a collection of 36 studies from the literature. This is also known as a meta-analysis. The associations of interest that we found were: average daily gain (ADG) of the calf was associated with daily forage intake, calves that were weaned, total starter intake, and total MR intake. Feed efficiency of the calf was associated with the weight of the ruminal contents, daily forage, milk replacer (MR), and starter intakes, percent of the diet composed of starter, and total starter intake. Daily forage intake was associated with the percent of the diet that was starter or MR. Daily starter intake was associated with acid detergent fiber in the starter, a pelleted starter (versus a texturized starter), diets including starter and forage (versus a MR only diet), and the percent of the diet that was MR. Daily MR intake was associated with the percentage of the diet that was starter, final body weight (BW), ruminal propionate concentration, and daily starter intake. These relationships emphasized that although dietary and environmental factors are more closely associated with calf performance, ruminal factors such as rumen contents and volatile fatty acid concentrations appear to have additional, additive influences on calf performance. The second part of the study objective was to explore an idea that, to our knowledge, has not been published in the literature. In the second study, 24 dairy calves were challenged with oral doses of a gram-negative bacteria lipopolysaccharide (LPS), and a short-chain fatty acid sodium butyrate. The hypothesis in this study was that the LPS and sodium butyrate would trigger metabolic pathways on the rumen cell membranes to a greater extent together, versus independently, to increase the amount of cells growing. Calves were assigned to one of four treatments: control (CON), butyrate (BUTY), LPS only (LPS-O), or LPS plus butyrate (LPSB). To study this effect, each treatment group was administered their respective treatment orally as a liquid twice daily. To measure the results, the following data was collected: feed intake, fecal and respiratory scores, rectal temperature BW, hip and withers height, blood samples, rumen content and pH samples, papillae area, epithelial thickness, and organ weights. Blood and rumen samples were analyzed for blood metabolites and volatile fatty acids concentrations respectively. Data were analyzed and results showed no difference amongst feed intake, health measures, rumen pH, rumen VFA concentration, and blood metabolites by treatment. Calves on the LPS treatment weighed more and had higher ADG than BUTY treatment calves. Withers height was higher in the LPS group when compared to CON. Stomach weights were higher in the LPSB group when compared to the BUTY group.

Full textGenetic evaluation systems are in rapid development worldwide. In most countries, “traditional” breeding programs based on phenotypes and relationships between animals are currently being integrated and in the future might be replaced by the introduction of molecular information. This thesis stands in this transition period, therefore it covers research on both types of genetic evaluations: from the assessment of the accuracy of (traditional) international genetic evaluations to the study of statistical methods used to integrate genomic information into breeding (genomic selection). Three chapters investigate and evaluate approaches for the estimation of genetic values from genomic data reducing the number of independent variables. In particular, Bonferroni correction and Permutation test combined with single marker regression (Chapter III), principal component analysis combined with BLUP (Chapter IV) and Fst across breeds combined with BayesA (Chapter VI). In addition, Chapter V analyzes the accuracy of direct genomic values with BLUP, BayesA and Bayesian LASSO including all available variables. The results of this thesis indicate that the genetic gains expected from the analysis of simulated data can be obtained on real data. Still, further research is needed to optimize the use of genome-wide information and obtain the best possible estimates for all traits under selection.

Full textThis dissertation investigates the dairy farming industry in the Northeastern United States and, in particular, the key drivers of economic viability and competitive advantage for small and midscale commercial dairy producers. The research approach employed was a literature review combined with primary case study observation and data collection. Historical perspective has been presented to provide an overarching contextual framework for this study. Four dairy farms were purposefully selected for case study research because they represented various aspects of a pre-defined set of variables and because they demonstrated relevant similarities as well as significant differences in terms of alternative business strategy. The classical business opportunity analytical process has been customized for practical use application by small and midscale dairy farmers. This tailored process has been validated using research findings; it offers a fresh way of identifying a strategic approach in pursuit of economic viability and competitive advantage that best fits an operation's unique set of characteristics. This process is intended for practical use application on a broader scale by dairy farmers in the Northeast to facilitate their understanding of challenging industry dynamics, of emergent market opportunity and inherent potency, and of both internal and external hurdles to be overcome. Finally, recommendations for next steps have been presented.
