description: Da Rocha and Rodigues (RR) claim (i) that in classical electrodynamics in vector calculus the distinction between polar and axial vectors and in exterior calculus between twisted and untwisted forms is inappropriate and superfluous, and (ii) that they can derive the Lorentz force equation from Maxwell's equations. As to (i), we point out that the distinction of polar/axial and twisted/untwisted derives from the property of the electric charge of being a pure scalar, that is, not carrying any screw sense. Therefore, the mentioned distinctions are necessary ingredients in any fundamental theory of electrodynamics. If one restricted the allowed coordinate transformations to those with positive Jacobian determinants (or prescribed an equivalent constraint), then the RR scheme could be accommodated; however, such a restriction is illegal since electrodynamics is, in fact, also covariant under transformations with negative Jacobians. As to (ii), the "derivation" of the Lorentz force from Maxwell's equations, we point out that RR forgot to give the symbol F (the field strength) in Maxwell's equations an operational meaning in the first place. Thus, their proof is empty. Summing up: the approach of RR does not bring in any new insight into the structure of electrodynamics.

description: The generation, processing and analysis of atmospheric model data are expensive, as atmospheric model runs are often computationally intensive and the costs of ‘fast’ disk space are rising. Moreover, atmospheric models are mostly developed by groups of scientists over many years and therefore only few appropriate models exist for specific analyses, e.g. for urban climate. Hence, atmospheric model data should be made available for reuse by scientists, the public sector, companies and other stakeholders. Thereby, this leads to an increasing need for swift, user-friendly adaptation of standards.The FAIR data principles (Findable, Accessible, Interoperable, Reusable) were established to foster the reuse of data. Research data become findable and accessible if they are published in public repositories with general metadata and Persistent Identifiers (PIDs), e.g. DataCite DOIs. The use of PIDs should ensure that describing metadata is persistently available. Nevertheless, PIDs and basic metadata do not guarantee that the data are indeed interoperable and reusable without project-specific knowledge. Additionally, the lack of standardised machine-readable metadata reduces the FAIRness of data. Unfortunately, there are no common standards for non-climate models, e.g. for mesoscale models, available. This paper proposes a concept to improve the FAIRness of archived atmospheric model data. This concept was developed within the AtMoDat project (Atmospheric Model Data). The approach consists of several aspects, each of which is easy to implement: requirements for rich metadata with controlled vocabulary, the landing pages, file formats (netCDF) and the structure within the files. The landing pages are a core element of this concept as they should be human- and machine readable, hold discipline-specific metadata and present metadata on simulation and variable level. This guide is meant to help data producers and curators to prepare data for publication. Furthermore, this guide provides information for the choice of keywords, which supports data reusers in their search for data with search engines. © 2020 The authors

description: A new superconformal mechanics with OSp(4|2) symmetry is obtained by gauging the U(1) isometry of a superfield model. It is the one-particle case of the new N=4 super Calogero model recently proposed in arXiv:0812.4276 [hep-th]. Classical and quantum generators of the osp(4|2) superalgebra are constructed on physical states. As opposed to other realizations of N=4 superconformal algebras, all supertranslation generators are linear in the odd variables, similarly to the N=2 case. The bosonic sector of the component action is standard one-particle (dilatonic) conformal mechanics accompanied by an SU(2)/U(1) Wess-Zumino term, which gives rise to a fuzzy sphere upon quantization. The strength of the conformal potential is quantized.

description: Food animal veterinarians are being challenged today to provide comprehensive cost-effective programs to increasingly sophisticated clients on intensive livestock operations. The delivery of such service is the greatest challenge facing the veterinary profession. The emphasis today, unlike the past, is on production within the herd rather than on the individual animal. To meet the needs of these producers, veterinarians are recognizing that certain clients are requesting changes in the veterinary/client relationship. Without question, the knowledge and expertise is currently available to provide "high tech" veterinary service to elite producers.

description: Equally challenging as establishing a production medicine practice, is establishing a fee structure satisfactory to all parties. A system working well for me is a monthly retainer fee. Each dairy is charged a monthly fee calculated from the number of cows on that month's DHI summary. The fee is charged on a regressive scale, creating larger per cow fees for small herds than for large dairies. This scale is limited by minimum and maximum fees.

Uncertainties in Segmentation and their Visualisation
Creators: name: Lucieer, Arko
Publisher: name: University Of Tasmania
Year: 2023

description: This thesis focuses on uncertainties in remotely sensed image segmentation and their visualisation. The first part describes a visualisation tool, allowing interaction with the parameters of a fuzzy classification algorithm by visually adjusting fuzzy membership functions of classes in a 3D feature space plot. Its purpose is to improve insight into fuzzy classification of remotely sensed imagery and related uncertainty. Additionally, alpha-shapes are used to visualise irregular shaped class clusters. The second part of the thesis describes segmentation techniques for identification of objects and quantification of their uncertainties. The Local Binary Pattern (LBP) operator is used to model texture. A multivariate extension of the standard univariate LBP operator is proposed to describe texture in multiple bands. Texture-based image segmentation, provides good results yielding valuable information about object uncertainty at transition zones. Visualisation methods described in the first part and segmentation techniques described in the second part are combined and extended to visualise object uncertainty. An object is visualised in 3D feature space and in geographic space based on a user-defined uncertainty threshold. Isosurfaces provide a visualisation technique for fast interaction facilitating visualisation of the relation between uncertainty in the spatial extent of objects and their thematic uncertainty.
Swiss Cheese and a Cheesy CMB

description: It has been argued that the Swiss-Cheese cosmology can mimic Dark Energy, when it comes to the observed luminosity distance-redshift relation. Besides the fact that this effect tends to disappear on average over random directions, we show in this work that based on the Rees-Sciama effect on the cosmic microwave background (CMB), the Swiss-Cheese model can be ruled out if all holes have a radius larger than about 35 Mpc. We also show that for smaller holes, the CMB is not observably affected, and that the small holes can still mimic Dark Energy, albeit in special directions, as opposed to previous conclusions in the literature. However, in this limit, the probability of looking in a special direction where the luminosity of supernovae is sufficiently supressed becomes very small, at least in the case of a lattice of spherical holes considered in this paper.

Each veterinarian has an area of special interest, and each works at a different speed. However, all of us do daily routine work with all species. For this reason, we have found charging by procedure a very effective way to standardize our fees.

Implications of railway relocation in Western Canadian cities : Saskatoon, a case study.
Creators: name: Lainsbury, John Michael
Publisher: name: University of British Columbia
Year: 2011

description: This thesis is a study of railway relocation and subsequent commercial redevelopment in Saskatoon, Saskatchewan. The primary purpose of the study is to test the hypothesis that railway relocation in a western Canadian city could prove beneficial to such a City in terms of community objectives. The City of Saskatoon is utilized as a case study. A secondary purpose, upon validation of the hypothesis, is to attempt the use of Saskatoon's experience as a bench-mark in determining the feasibility of railway relocation in other Saskatchewan cities. In order to place the City in its proper historical and developmental context, the history of Saskatoon is briefly traced from its origin in 1882 to the present. This review pictures Saskatoon as a dynamic urban center with a relatively bright future. A detailed review of events and negotiations leading up to the joint decision by the City and the C.N.R. to relocate railway facilities from downtown Saskatoon indicates that the primary community objectives involved were consolidation of the downtown area and improvement of access to the downtown area. These and other objectives are discussed in detail and analyzed in terms of their relevance and where possible, in terms of the magnitude of costs associated with achievement of a particular objective. The impact of the commercial development proposed for construction in the area vacated by the C.N.R. is demonstrated in terms of its effect on the supply of downtown retail space as opposed to the projected demand. On the basis of certain explicit assumptions, this analysis predicts an excess supply of retail floor space for a period of eight years. Quantifiable costs and benefits to the City attributable to relocation are compared with the resulting conclusion that, on the basis of current estimates, benefits accruing from relocation will yield a 9½% return on the City's investment by 1984. A subjective evaluation of non-quantifiable costs and benefits results in the further conclusion that benefits will again exceed costs. The aggregate conclusion, which validates the hypothesis, is that railway relocation in Saskatoon will prove beneficial to the City in terms of community objectives. The key factors which led to consideration of railway relocation in Saskatoon and which made the project viable were the dynamic nature of the city; the relative location of railway facilities; demand for retail space, and the location of railway rights-of-way relative to the location of required traffic facilities. These factors are tested against four other cities in Saskatchewan; Regina, Moose Jaw, Prince Albert, and Swift Current. Of the four, only Regina is consistantly comparable to Saskatoon, leading to the conclusion that detailed investigation of railway relocation from downtown Regina is warranted.It is further concluded that railway relocation from other Canadian cities might be equally feasible, and certainly worthy of further study.

description: In the context of modified Newtonian dynamics, the fundamental plane, as the observational signature of the Newtonian virial theorem, is defined by high surface brightness objects that deviate from being purely isothermal: the line-of-sight velocity dispersion should slowly decline with radius as observed in luminous elliptical galaxies. All high surface brightness objects (e.g. globular clusters, ultra-compact dwarfs) will lie, more or less, on the fundamental plane defined by elliptical galaxies, but low surface brightness objects (dwarf spheroidals) would be expected to deviate from this relation. This is borne out by observations. With MOND, the Faber-Jackson relation (the power-law relation between luminosity and velocity dispersion), ranging from globular clusters to clusters of galaxies and including both high and low surface brightness objects, is the more fundamental and universal scaling relation in spite of its larger scatter. Faber-Jackson reflects the presence of an additional dimensional constant (the MOND acceleration) in the structure equation.

New Approach to Electrolyte Therapy

Year: 1992

description: Oral electrolyte administration remains the mainstay of therapy of calf diarrhea. Solutions can effectively combat dehydration if they are administered in sufficient volume (6.5 to 8.5 L daily) alone or in combination with milk. Hypertonic oral electrolyte solutions are the most calorie dense of the oral electrolyte solutions and are superior to most isosmolar solutions in their ability to resolve metabolic acidosis and electrolyte derangements of the scouring calf. Continued milk feeding combined with administration of oral electrolyte solution for treatment of diarrhea can satisfactorily meet the calf's caloric requirements for maintenance and growth, increase weight gain, improve glucose homeostasis, and shorten the course of diarrhea. Provision of fiber and beneficial intestinal microflora in oral electrolyte solutions have potentially beneficial outcomes but remain to be tested in field studies.

description: Dark matter decaying or annihilating into mu+mu- or tau+tau- has been proposed as an explanation for the e+e- anomalies reported by PAMELA and Fermi. Recent analyses show that IceCube, supplemented by DeepCore, will be able to significantly constrain the parameter space of decays to mu+mu-, and rule out decays to tau+tau- and annihilations to mu+mu- in less than five years of running. These analyses rely on measuring track-like events in IceCube+DeepCore from down-going nu_mu. In this paper we show that by instead measuring cascade events, which are induced by all neutrino flavors, IceCube+DeepCore can rule out decays to mu+mu- in only three years of running, and rule out decays to tau+tau- and annihilation to mu+mu- in only one year of running. These constraints are highly robust to the choice of dark matter halo profile and independent of dark matter-nucleon cross-section.

Clotting Factor in Bovine Preruminant Nutrition
Creators: name: Thomkins, Trevor
name: Drackley, James K.
Publisher: name: American Association of Bovine Practitioners  Proceedings of the Annual Conference
Year: 1992

description: During the process of digestion in the preruminant calf, the casein protein in cows' milk clots in the abomasum due to the action of the enzymes pepsin and rennin (chymosin) and hydrochloric acid. The importance of this clotting mechanism has been studied, but the physiological implications are not fully understood. Today in the United States, many calves are raised very successfully on milk replacers that do not contain casein protein because skim milk powder, which is the main source of casein, is prohibitively expensive. Instead, whey proteins are the predominant source of milk proteins in calf milk replacers. Research indicates that whey proteins, which do not clot in the abomasum, are as efficacious as casein proteins in the diet of the preruminant calf. The subject of "clotting" has become topical due to an attempt through the National Dairy Heifer Evaluation Program (which is a part of the National Animal Health Monitoring System) to evaluate milk replacers on farms by a rennet clotting test. This test was developed in Europe to determine the presence of heat denatured skim milk in calf milk replacers and has no relevance to milk replacers formulated on the basis of whey proteins. This paper reviews the physiology of digestion in the calf, discusses the implications of milk clotting and addresses the issues of modern milk replacer formulations.

Recent Calf Milk Replacer Research Update

Publisher: name: American Association of Bovine Practitioners  Proceedings of the Annual Conference
Year: 1992

description: The first calf milk replacer in the United States was developed and introduced in 1951 to dairy producers. Since the original calf milk replacer, there have been many nutritional advances in calf milk replacers and calf raising programs. During the last ten years, there has been less and less research information concerning the young calf occurring in scientific literature. Those researchers who consider themselves as primarily working in the area of calf nutrition and health are also fewer in number. For these reasons, this paper will present mainly primary source information rather than review information, in order to add to the scientific information base. This paper will discuss the key nutritional principles as it relates to milk replacer feeding and composition along with some of the newer calf milk replacer areas. The application of the information presented shall be limited to the herd replacement and dairy beef calf. Spanish and French summaries on PDF

description: If dark matter decays into electrons and positrons, it can affect Galactic radio emissions and the local cosmic ray fluxes. We propose a new, more general analysis of constraints on dark matter. The constraints can be obtained for any decaying dark matter model by convolving the specific dark matter decay spectrum with a response function. We derive this response function from full-sky radio surveys at 408 MHz, 1.42 GHz and 23 GHz, as well as from the positron flux recently reported by PAMELA. We discuss the influence of astrophysical uncertainties on the response function, such as from propagation and from the profiles of the dark matter and the Galactic magnetic field. As an application, we find that some widely used dark matter decay scenarios can be ruled out under modest assumptions.

Colostrum

description: Despite increasing awareness of the importance of passive immunity in calves to reduce disease prevalence, morbidity from calfhood diseases, days to first illness, sick days, days of viral shedding, viremia, growth and productivity(l-6), 20 to 30% of neonates will be hypo- or agammaglobulinemic. Failure of passive transfer of maternal immunoglobulins (FPT) occurs when there is a problem with 1 or more of the 3 phases of passive transfer: formation of colostrum with a high concentration of immunoglobulin, ingestion of an adequate volume of colostrum by the calf in a timely fashion, or efficient absorption of colostral immunoglobulin. Some calves with FPT are healthy and productive neonates, which is a reflection of the importance of other factors including environmental conditions, management practices, pathogen load, pathogen virulence, and nutrition of the calf in addition to acquisition of passive immunity. There is general acceptance that failure of passive transfer exists when calves between 36 and 48 hours of age have serum immunoglobulin concentrations less than 1000 mg/di. Individual calf problems can occur when its serum immunoglobulin concentration is below 1000 mg/di; herd problems occur with increased prevalence of scours and respiratory disease occur when large numbers of calves have FPT.

The dark energy field can be coupled strongly enough to Standard Model particles to be detected in colliders, and the model requires only modest additional particle content and little or no fine-tuning other than a new energy scale of order milli-electron volts.

The influence of feminism on public policy abortion and equal pay in Australia and the Republic of Ireland
Creators: name: Shannon, EA
Publisher: name: University Of Tasmania
Year: 2023

description: Feminism is a major force for change in late twentieth century liberal democratic political systems. This thesis is concerned with determining the factors involved in successful feminist policy intervention. It achieves this by developing a set of indicators by which to identify the presence of feminist influence and an analytical model by which to explain the influence of feminism on public policy. These are then applied to the development of abortion and equal pay policy, between the mid 1960s and the mid 1990s, in Australia and the Republic of Ireland. The model contains three factors: the material, normative and analytical aspects of feminist activity; the political, social and economic systems of national receptivity; and the intensity and scope of conflict involved with particular policy types. An examination of the lengthy history of feminist activism in Australia and Ireland contrasts a highly conflictual policy (abortion) with one which is less conflictual (equal pay); compares national variations in terms of predisposition to feminist influence; and chronicles the ebb and flow of feminist policy

description: Bovine viral diarrhea virus (BVDV) is a ubiquitous virus that is the most frequently isolated viral pathogen of cattle in some areas. BVDV virus infection is often suspected because of the wide range of disease problems it causes. This variety of clinical signs has complicated the diagnosis of this viral infection because there are no simple answers. It is, however, essential that a definitive diagnosis be made before costly control measures are implemented.

description: Bovine viral diarrhea virus (BVDV) is an ubiquitous viral pathogen of cattle that induces disease involving the respiratory, enteric, reproductive, lymphoid, and nervous systems. The diseases commonly associated with BVDV infections are termed acute BVD, mucosal disease, and chronic BVD. In North America, BVDV is a leading cause of economic loss in beef and dairy cattle. Two biotypes of BVDV exist, and these have cytopathic or noncytopathic characteristics in cell culture. The cytopathic virus kills susceptible cell cultures and the noncytopathic virus has little effect on cultured cells. However, there is no correlation between the effects of virus in cell culture and the effects in cattle. Certain noncytopathic BVDV are extremely virulent and kill adult cattle. Conversely, many cytopathic BVDV induce only mild disease in cattle.

description: Freshwater fishes are increasingly being considered threatened at regional (Bruton, 1990; Moyle, 1995; Fu et al., 2003) and international (Cambray & Giorgio Bianco, 1998) levels. In order to maintain their associated fishery resources, aquatic biodiversity, and the health of the systems which they inhabit, freshwater fish conservation has been recognised as an important action globally (Lowe-McConnell, 1990; Cowx & Collares-Pereira, 2002). A broad range of threats, which are mostly linked to anthropogenic impacts and biological invasions, increase the vulnerability of fishes (Bruton, 1995).
The volunteer citizen, health services and agency : the identity work of Australian and New Zealand ambulance volunteers
Creators: name: Stirling, Christine
Publisher: name: University Of Tasmania
Year: 2023

description: This thesis is an investigation of the interface between service volunteers in Australia and New Zealand and ambulance service organisations using a framework that situates them in a changing cultural and structural environment. This topic is particularly important in a political context where volunteers are viewed as a policy solution to a diversity of social ills, and where recent neoliberal policies and managerial cultural shifts have changed the service environment. Specifically this study focuses on how control and agency are evident within volunteer identity work and how this can inform our understanding of the problems experienced in the integration of volunteers into services. Empirical data was gathered in the form of texts that reflected volunteer identity work at the political level (political speeches of key Australian and New Zealand politicians), the ambulance service management level (ambulance documents and interviews with managers) and ambulance service volunteers (interviews with volunteers and secondary data from open-ended survey questions). A critical discourse analysis (Fairclough 1992, 2003) of the data involved firstly generating broad identity themes from the data. Key texts that strongly reflected identity work were then selected for an in-depth textual analysis. This study found four key identities for ambulance volunteers in use within ambulance services: the Moral Volunteer, the Professional Volunteer, the Staff Volunteer, and the Self-interested Volunteer. These identities reflected a diverse range of volunteer and managerial interests. Volunteer interests were shown to include material and emotional concerns, at a personal and collective level. However, ambulance volunteers were found to lack collective agency, which led to inequitable treatment within ambulance services. Ambulance volunteers were generally under-resourced and under-managed, and the effects of this flowed to rural populations which consequently received a lower standard of service. Based on the empirical findings and drawing on governmentality theory (Foucault 1991a) and critical realist theory (Archer 2000; Bhaskar 1975), an explanatory theory of volunteering is constructed. The concepts of identity and agency allow the complexity of the volunteer/service organisation interface in a cultural and structural context to be incorporated into empirical studies. Service volunteers are conceptualised as collectives of individuals with diverse interests and local level concerns. Implications for practice include understanding how the volunteer/service interface is likely to experience ongoing difficulties without changes to organisational structures and changes to 'thinking' about volunteers.
Aboriginal convicts: race, law, and transportation in colonial New South Wales
Creators: name: Harman, Kristyn

description: This thesis challenges the long-standing convention within Australian historiography whereby 'Aborigines' and 'convicts' have been treated as two distinct categories. It identifies the points at which these descriptors converge, that is, in the bodies of Aboriginal men from New South Wales sentenced to banishment or transportation. It locates their experiences on a trajectory extending from the early part of the nineteenth century through to the formative middle decades during which the rationale underpinning the trial and transportation of Aboriginal men was refined by the colonial state. In the opening decades of the nineteenth century colonial governors occasionally exercised their prerogative to banish Aboriginal men considered fomenters of hostilities against the colonists. However, they were constrained from making public examples of such men by way of staging trials as early legal opinion railed against doing so. By the middle decades of the nineteenth century colonial discourses constructing Aborigines as British subjects were deployed to argue for the sameness of Aboriginal and white subjects before the law. The perverse corollary of affording Aboriginal people protection under the law was that they also became accountable under colonial laws whose functions were often well outside their ambit of experience. This thesis argues that advocating equal treatment for all served to naturalise the disadvantages faced by Aboriginal defendants in the colonial courtroom thus facilitating trials described as farcical by some contemporaneous commentators. It demonstrates that situating Aboriginal people as British subjects facilitated the criminalisation of some acts that might otherwise be read as political resistance as it was reasoned that one cohort of British subjects could not be considered to be at war with other British subjects. Paradoxically, atypical treatment of Aboriginal people both within and beyond the courtroom was predicated on notions of difference. This led, for example, to the employment of court interpreters to facilitate the trials of Aboriginal defendants. Difference also informed official edicts eventually issued in relation to Aboriginal deaths in custody later in the middle decades of the nineteenth century. Most of all, notions of difference underpinned the rationale of exemplary sentencing that saw sixty Aboriginal men from New South Wales incorporated into the convict system during the first half of the nineteenth century as a strategy to subdue not only the captives but also their respective communities. Tellingly, no Aboriginal women became convicts. It was men, not women, who colonists considered to be martial enemies.
BVD Vaccines - Is There An Answer

description: Problems associated with bovine viral diarrhea virus (BVD) infections seem to be increasing in the United States. I get many questions from veterinarians and investigate more and more BVD infected herds. Most of these herds do not exhibit any outward clinical signs of BVD infection but reproductive problems or underlying immune suppression are often seen.

Getting a Diagnosis in an Abortion Storm

description: Determining the cause of abortions presents many problems. This is reflected in the fact that the diagnostic success of laboratories in bovine abortion is only 30-40% (1,2). The reasons for this relatively low diagnostic success are numerous. Abortion results from an event that frequently occurred weeks or months earlier. The cause, therefore, may be undetectable in the fetus at the time of abortion. The fetus is often retained in the uterus hours to days after death, and autolysis obscures lesions that are present. The placenta is often affected first and most consistently but is frequently unavailable for examination (1). The lack of relevant history, clinical signs and frequent negative necropsy findings force the diagnostician to look for every infectious agent that might be involved. Therefore, the laboratory tests for all the etiological agents frequently associated with abortion. The techniques used will vary somewhat between laboratories but will include what can be tested for within a reasonable amount of time and some degree of accuracy.

Influence of Nutrition and Weight Loss on Reproduction and Early Embryonic Death in Cattle

Year: 1992

description: Maintaining acceptable levels of reproductive performance in cattle is a challenging problem, particularly when cows are producing high yields of milk or when nutrient intake is below the demand for extended periods of time. In such situations, the associated negative energy balance may result in prolonged postpartum anestrus, lower levels of progesterone secretion by corpora lutea (CL) and lower rates of conception. Fertility in high-producing cattle also may be affected by excessive intake of protein, inadequate intake of fibrous feeds or other nutritional imbalances. There is some evidence that such factors affect embryonic survival. This paper will review some of the current thinking in these areas and provide insights into potential biological mechanisms through which fertility is influenced by these factors. The paper will focus primarily on the postpartum dairy cow.

The one-dimensional KPZ equation: an exact solution and its universality

description: We report on the first exact solution of the KPZ equation in one dimension, with an initial condition which physically corresponds to the motion of a macroscopically curved height profile. The solution provides a determinantal formula for the probability distribution function of the height $h(x,t)$ for all $t>0$. In particular, we show that for large $t$, on the scale $t^{1/3}$, the statistics is given by the Tracy-Widom distribution, known already from the theory of GUE random matrices. Our solution confirms that the KPZ equation describes the interface motion in the regime of weak driving force. Within this regime the KPZ equation details how the long time asymptotics is approached.

description: The intramammary administration of antibiotics is the most common method used to treat bovine mastitis (1). Antibiotic treatment during lactation has a low cure rate for many mastitis pathogens, and the loss of milk due to drug residues results in a poor cost-benefit ratio for most antibiotic therapy during lactation (2). In addition, there is an increasing concern over the presence of drug residues in milk (3), which has led to the search for alternatives the classical antibiotic approach (4,5,6,7,8). The bacteriocins, lysostaphin (9) and nisin (10), are effective toward mastitis pathogens. These are nontoxic proteins, digested and inactivated by intestinal enzymes, and thus, are potentially less hazardous than the antibiotics currently available for use in dairy cattle (6). This study examined the efficacy of several lysostaphin and nisin combinations for the treatment of experimental bovine mastitis infections by Staphylococcus aureus, Streptococcus agalactiae, and Streptococcus uberis.

Residue Phobia, Residue Avoidance and the Real World
Creators: name: Belschner, Austin P.
Publisher: name: American Association of Bovine Practitioners  Proceedings of the Annual Conference
Year: 1992

description: The goal of this paper is to deal with food safety and veterinary therapeutic issues from the consumer, veterinarian and pharmaceutical industry perspective. We start with problems the food animal veterinary practitioner faces concerning the choice of therapeutic agents. Next, safety issues concerning these agents are dealt with, in an attempt to provide background information on the approval process for therapeutic agents that are used in lactating dairy cattle. We build on the safety issues by describing how residue testing is done by the dairy industry. And finally, the Upjohn Company's injectable antibiotic, Naxcel® Sterile powder (Ceftiofur sodium), is used as example of how new generation therapeutic agents can be developed and approved under guidelines that meet the consumer's need for safe dairy products and still provide the veterinarian with efficacious treatments for their patients.

Year: 1992

description: The Milk and Dairy Beef Quality Assurance Protocol (MDBQAP)1 began as a collaborative effort on the part of the American Veterinary Medical Association (AVMA) and the National Milk Producers Federation (NMPF) to overcome unfavorable publicity, which was scientifically unsubstantiated, regarding pharmaceutical residues in milk which had been sold in certain areas of the United States. In addition there existed concern over the incidence of pharmaceutical residues occurring in cull dairy cows as reported by the U.S. Department of Agriculture, Food Safety Inspection Service. Since both veterinarians and producers were implicated in these issues, it was loitcal that the two organizations cooperate and respond in a proactive manner.
