description: Pregnancy rate, a function of heat detection and conception rate, determines the number of days postpartum at which cows become pregnant from the voluntary waiting period.67 Cows expressing one or more estruses during the first 30 days postpartum had improved pregnancy rates compared with anestrous cows.83 This observation indicates that the physiological and hormonal events associated with estrus help restore uterine and ovarian function to a state conducive to pregnancy. A number of studies have demonstrated the relationship between hypocalcemia and parturient disorders such as dystocia, retained fetal membranes (RFM), and ketosis.13,30,68 These disorders predispose the cow to metritis, which can affect the energy status of the cow. This influences ovarian activity and resumption of cyclicity during the postpartum period. The energy status of the lactating dairy cow has differential effects on early follicular development and competence, ovulation and subsequent corpus luteum (CL) function during the postpartum period. As our understanding of the endocrinology and reproductive physiology of the postpartum cow has advanced, it is clear that reproductive and nutritional management systems need to be integrated to achieve optimal reproductive efficiency. Objectives of this presentation are 1) to describe the association between calcium status and periparturient disorders 2) to relate the differences in ovarian activity to energy status in postpartum dairy cows 3) to examine the effects of protein and fat on reproductive function during the postpartum period, and 4) to document the beneficial effects of bovine somatotropin (bST) on first-service pregnancy rates when integrated into a reproductive management program for timed insemination.

Year: 1999

description: Infectious diseases are among the most important problems in all types of livestock production. Costs can be tremendous to a single operation for diagnosing and treating sick animals, or associated with death losses. However, these probably are far outweighed by such hidden costs as associated with decreased production efficiency or lost production opportunities. Less-immediate losses that also must be considered include those linked to the inability to market stock because of the potential spread of infection.

description: It is likely that Archaean cratons of Laurentia had different palaeogeographic histories prior to their amalgamation. New palaeomagnetic, geochronological and geochemical evidence supports a reconstruction of the Wyoming craton adjacent to the southern margin of the Superior craton at 2.16 Ga, before rifting (c. 2.1–2.0 Ga) and eventual reamalgamation after the Hudsonian Orogeny (c. 1.8 Ga). U–Pb ages (TIMS on baddeleyite) from five dykes yield two groups of ages at c. 2164 and 2155 Ma. The younger group of ages defines the Rabbit Creek swarm at 2161–2152 Ma and precisely dates its palaeomagnetic pole. Two large and differentiated dykes (>100 m) in the Bighorn and Wind River uplifts are geographically related to the Rabbit Creek swarm but have slightly different orientations and yield slightly older ages at 2171–2157 Ma. These dykes may be parts of a single intrusion (the ‘Great Dyke of Wyoming’) that spans over 200 km between uplifts, possibly representing a different magmatic event. This older event does not have enough distinct intrusions to provide a correctly averaged palaeomagnetic pole, but correlates with magmatism in the Superior craton and has a palaeomagnetic remanence comparable to the Rabbit Creek dykes. With minor tilt corrections, the palaeomagnetic data from the Rabbit Creek swarm and Powder River–South Pass dykes support a reconstruction of the southeastern Wyoming craton against the southern Superior craton. This fit juxtaposes the Palaeoproterozoic Huronian and Snowy Pass Supergroups along two passive margins that experienced a prolonged period of mafic magmatism (>100 myr) and rift basin development. Although there are slight geochemical variations across the Rabbit Creek swarm, all dykes fit into two distinct groups that are independently dated and internally consistent.

Year: 1999

description: Records are an essential component of herd health programs and beef quality assurance programs. They are used to optimize production efficiency and monitor and verify procedures for beef quality and food safety. Recently, health organizations around the world have stated that production records required to show prudent drug use by veterinarians and producers. The development of resistance in zoonotic organisms may be promoted by the inappropriate use of antimicrobials in animals. Therefore, treatment records are required to show the public that antimicrobials are used judiciously in food animal production for clinical and production efficacy, while minimizing antimicrobial resistance impacts on human health.

description: As we look to the turn of the century, many new theories and technologies are evolving to help us succeed in decreasing the onset of diarrheal disease or diminishing its impact on the neonatal bovine. This discussion will focus on many of these disease agents. The bovine practitioner must realize that definitive work on applied use of many of these factors (e.g. "field studies") is not yet under way. Existing products of which the authors are aware will be mentioned, but should not be interpreted as an endorsement. They are mentioned to provoke thought and provide information about potontial future therapies that may be used to bring further success in therapy and prevention of diarrheal disease. We would first like to discuss agents that alter the ability of enteropathogens to colonize the gut or adhere to the gut through interference of mucosal binding. The second part of this paper will discuss our greater comprehension of new elements of oral rehydration solution (ORS) therapy. We will describe our efforts to manipulate these solutions to enhance net absorption of water and increase the healing of the damaged intestinal villus.

The Use of Antimicrobials in Beef Cattle Health Management and Production and the Development of Antimicrobial Resistant Pathogens and their Transfer to Humans Causing Disease Which is Difficult to Treat
Creators: name: Radostits, Otto M.
Publisher: name: American Association of Bovine Practitioners  Proceedings of the Annual Conference
Year: 1999

description: In food-producing animal health management and production, antimicrobials are used for the treatment and prevention of infectious diseases, and to enhance growth promotion. These uses of antimicrobials represents one of several important health management strategies which contribute to animal health and well-being and to the economical production of wholesome meat and milk products. The control of animal disease also means control of certain infectious diseases which may be transmitted to humans. However, there are some potential human health hazards associated with antimicrobials used in food animals. Residues of drugs may occur in meat and milk and could enter the human food chain and increase the risk of ill-health in persons who consume products from treated animals. Of greater current importance is the potential for the emergence of antimicrobial resistant enteric bacteria which could be transferred to humans resulting in clinical disease which may be difficult to treat. This paper will review the evidence that the use of antimicrobials in beef cattle health management and production in North America allows the emergence of antimicrobial resistant bacteria, which may be transferred to humans and subsequently cause disease which is difficult to treat because of antimicrobial resistance. Some of the scientific publications and other documents which have examined the various aspects of antimicrobial resistance over the last 30 years will be summarized and their conclusions examined. Some historical aspects are included in an attempt to better the understand the problem. Some references to the use and effects of antimicrobials in health and production management in swine and poultry will be made for comparative purposes.

Publisher: name: American Association of Bovine Practitioners  Proceedings of the Annual Conference
Year: 1999

description: Properly ensiled forages and grains are bio-secure when fed to dairy cows.7 Silage management is, therefore, important to dairy health and profitability. Veterinarians offering production medicine consultation to dairy producers must be knowledgeable about ensilage. Pathogens are present in silage regardless of how well it is preserved. Problems that may occur include ensiling forages: 1) too wet, resulting in clostridial fermentation and causing reductions in voluntary feed intake, 2) that deteriorate upon extreme aerobic instability, resulting in growth of Listeria monocytogenes, and causing listeriosis, and 3) too dry, producing aerobic instability problems with molds and mycotoxins.

Coping With Catastrophic Ensiled Forage Losses
Creators: name: Seglar, Bill
Publisher: name: American Association of Bovine Practitioners  Proceedings of the Annual Conference
Year: 1999

description: Providing cattle the highest quality ensiled forages and grains possible for maximum milk and beef productivity is a goal for most crop growers and cattle feeders. Pre-harvest weather related catastrophes such as flood, drought, wind, hail, and early frost can jeopardize this feeding goal, causing yield losses and reduction of nutrient quality of forages and grains. Harvest delays due to rainy seasons present another reason why quality crops may become less than ideal when fed out of the silo. These situations are out of the manager's control. Post-harvest silage catastrophes within manager control include the ensiling of quality crops with less than ideal ensiling management practices. This includes situations where crops are ensiled with improper moisture, maturity, packing, sealing, and feedout management. Aerobically unstable or Clostridial silages are the most common result when dealing with pre- and post-harvest catastrophes. Managing weather damaged crops prior to harvest and dealing with post-ensiling challenges requires managers to work with the principles of fermentation. 2,5

Recently, there has been increasing public concern about the use of antimicrobials in livestock production because this practice may contribute to the emergence of antimicrobial-resistant bacteria that could directly or indirectly cause bacterial resistance in human pathogens. There is limited scientific data to show that the use of antimicrobials in beef feedlot production is responsible for the emergence of resistant bacteria in human populations

description: U–Th–Ra isotope analyses of whole rocks and mineral separates were conducted in order to perform isochron dating of three morphologically young lavas from Tatun volcano, northern Taiwan (from Mt Cising, the Shamao dome and the Huangzuei volcano). The data do not yield tight U–Th isochrons, indicating open-system magmatic processes. However, crystallization ages of two samples can be constrained: namely, less than about 1370 years for the Shamao dome, based on 226Ra–230Th disequilibrium in magnetite, and less than approximately 70 ka (but potentially Holocene) for a Huangzuei flow, based on 238U–230Th disequilibrium in plagioclase. Discordant Ar–Ar, 238U–230Th and 226Ra–230Th ages are best explained by young lavas having inherited some crystals from older lithologies (crystal mushes or rocks), and indicate that the above ages represent maxima. Our study provides the first evidence of effusive volcanism at the Tatun Volcano Group in Late Holocene times. All separates from the Shamao dome and Huangzuei volcano are in 234U–238U equilibrium. Minerals in the Mt Cising sample are in 234U–238U disequilibrium, despite the 234U–238U equilibrium of the whole rock. We interpret this as uptake of a hydrothermally altered, old crystal cargo into fresh melt prior to eruption. A different dating approach will thus be required to constrain the eruption age of Mt Cising.

description: Clostridium perfringens is divided into five types on the basis of its ability to produce one or more of the so-called major toxins (Table 1). Type A strains are those which produce alpha toxin (a characteristic of all, or nearly all, isolates) and which do not produce beta, epsilon, and iota toxins. They are widespread in the intestines of warm-blooded animals and in the environment,36 and are well-known causes of wound contamination, anaerobic cellulitis, and gas gangrene in humans.15 Strains of type A are associated with a wide variety of disease processes in many organ systems of myriad species of domestic animals.

Botulism Toxicosis of Cattle

Publisher: name: American Association of Bovine Practitioners  Proceedings of the Annual Conference
Year: 1999

description: Botulism in cattle is occurring with greater frequency in North America, coincident with increased frequency of large plastic bags used to store forage and with the increased use of small grain (ryelage) haylage. The clinical signs of botulism in cattle are very characteristic, almost pathognomonic if epidemiological factors are considered. Nearly always multiple cattle in a herd, within a few days of each other, have clinical signs of progressive muscular weakness leading to recumbency over a 2-5 day period of time. Perhaps the most dramatic, characteristic, clinical sign is the loss of normal lingual tone, to the point that the tongue will hang out of the side of the mouth. However, in order to elicit this finding, the tongue needs to be grasped manually and then pulled out of the side of the mouth with the jaws closed. In normal cattle, the tongue will then be retracted back into the mouth. Abnormal tongue tone, as occurs with botulism, will be manifest by both loss of normal muscular tongue tone and lack of prompt response to retract the tongue into the mouth. A limp tongue is clearly abnormal and with loss of ability to swallow, suggests botulism. Types A, Band type C botulism occur in cattle in the USA, but type B predominates. Type B is associated with feeding improperly fermented forage where the pH has not reached 4.5 or lower. Acid pH inhibits sporulation preventing botulinum toxin from being produced. Type C botulism occurs with the accidental feeding of carrion (birds, cat or dog carcasses) in the ration to cattle. Definitive diagnosis is challenging, often requiring multiple samples of forage, rumen contents, and/or fecal samples to be tested for botulinum spores and toxin in a laboratory experienced in botulinum testing.

Treatment of Clinical Mastitis

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

description: Mastitis continues to be of great importance to the US dairy industry. When diseases on dairy farms were recently evaluated according to effects on productivity, international trade, animal welfare, and zoonotic risk, mastitis ranked highest, above salmonellosis, paratuberculosis, and bovine virus diarrhea.1 Subclinical mastitis caused by contagious mastitis pathogens still causes substantial economic loss on some US dairy farms, but it can readily be controlled by dry cow antibiotic therapy, hygiene practices in the milking parlor, and selective culling. In herds that have achieved contagious mastitis control, clinical mastitis caused by opportunistic pathogens in the environment or on teat skin is the predominant form of the disease.2,3 Because these pathogens are ubiquitous, eradication of clinical mastitis is an unreasonable goal. Rather, dairy producers must strive to reduce the incidence of clinical mastitis by instituting hygienic practices that minimize exposure of teats to pathogens and by optimizing immune function through proper nutrition and vaccination. When clinical mastitis develops, as it does at an annual incidence rate of < 5% to > 50%,4 veterinarians and dairy producers must make appropriate treatment decisions. Despite decades of treating clinical mastitis, controversy still exists about when and how to treat it, particularly in herds that have controlled contagious pathogens. The predominant mastitis-causing pathogens in those herds are coliform bacteria, Streptococcus spp. other than Streptococcus agalactiae (environmental streptococci), and Staphylococcus spp. other than Staphylococcus aureus.2,3 An ideal treatment regimen would be one that is safe, reduces pain and suffering, is efficacious (resulting in rapid clinical and bacteriological cure), causes short milk and slaughter withholding times, avoids unnecessary drug use or excessive labor, positively impacts milk production and survivability, and is economical. Almost certainly the ideal regimen would differ for mild, moderate, and severe episodes of clinical mastitis and episodes caused by different pathogens. Hundreds of different treatments for clinical mastitis are used daily on US dairy farms, but, in general, even the most common treatments have not been studied in controlled clinical trials to determine if they are better than no treatment at all. In the remainder of this paper, I will discuss some of the common treatments for clinical mastitis in herds that have controlled contagious mastitis, and suggest areas for future study.

The Veterinary Antimicrobial Decision System

Year: 1999

description: Information on reasonable antimicrobial regimen design, particularly for extra-label use, is not currently available in a single easily-accessible source. Sources of information are scattered and may be difficult for the practitioner to locate in a timely manner. Even if the data are located, the interpretation may not be evident to the practitioner, particularly interpretation of pharmacokinetic and pharmacodynamic data. The need for a system designed for the food animal veterinary practitioner is also apparent as the discussion in the public health venue focuses on the appearance of antimicrobial-resistant human pathogens. The correlation between antimicrobial use in food animals and the appearance of resistant pathogens in the human population may not be unequivocally established. However, there is little doubt that antimicrobial use, whether in human or veterinary patients, may affect microbial populations by selecting for resistant organisms. Therefore, a need exists for the prudent use of antimicrobials such that efficacy is maximized while selection for resistant pathogens is minimized. Prudent use also contributes to longevity of the clinical utility of antimicrobials we currently have. These statements are made realizing that we know a lot more about maximizing efficacy than minimizing resistance development. With these needs in mind, the AABP, along with the Academy of Veterinary Consultants (the first to financially support the effort), the National Cattlemen's Beef Association, the American Association of Swine Practitioners, and the American Veterinary Medical Association have contributed a total of $189,000 as startup money over a 3 year period. Supporting funds started to arrive in March of 1999.

description: Metal migration processes, by means of gas-transported particles, from an iron magnetite skarn deposit beneath Quaternary transported overburden, to surface was studied at the Kaxiutata iron deposit. This study area is located in the desert of the Inner Mongolia region in northern China. Ascending gas-transported particles were collected using passive adsorption methods; a total of 50 samples were obtained over the known mineralization (30 within the mining area and 20 from the exploration area), and 15 samples were collected over background areas for comparison. The morphology, categorization, and chemical composition of particles in these samples were determined by transmission electron microscopy (TEM). In the mining and exploration area, the particles related to the subsurface mineralization (ore-bearing particles) are primarily Fe-, Cu-, Zn-, Pb-, and Bi-bearing, and particles show significant common characteristics. Sulphur is generally absent, or its content is notably low. However, based on the geological description of primary mineralization, Cu, Zn, and Pb occur mainly as sulphides, implying that the minerals were subjected to in situ or transport-associated oxidation. Most particles are actually aggregates of various smaller particles of diverse origin. Evidence of oxidation and agglomeration of particles may reflect the high porosity and gas permeability of the sandy overburden, which provides an oxidizing environment for gas-transported particles. The distribution of ore-bearing particles is correlated with the subsurface mineralization. Iron-rich particles (> 30% Fe) and Cu-, Zn-, and Bi-bearing particles collected above the mining area were also collected in the exploration zone, and these types of particles are likely indicators of underlying iron mineralization. Samples collected from the background zone revealed no Cu-, Bi-, Mo-, and Pb-bearing particles. The migration mechanism of gas-transported particles in the desert area is summarized and discussed based on this and previous studies.

description: Periparturient cows are immunosuppressed. Critical neutrophil functions (egress and phagocytic activities) and lymphocyte functions (immunoglobulin and cytokine secretion) are all impaired during this time. Exact causes ofperiparturient immunosuppression are not known but tremendous fluxes in endocrine factors undoubtedly effect changes in immunological competence. Periparturient cows experience large changes in plasma concentrations of vitamins and also are adjusting to the calcium, energy and protein demands necessary for lactation. The end of gestation appears to induce a progressive suppression of immune function. There appears to be a teleological basis for suppression of antigen specific immunity in the periparturient female. Development of immunity against self and paternal antigens released into the cow as a consequence of tissue damage associated with parturition would serve little useful purpose. However, as a result of this suppression, innate immune function is also impaired (perhaps inadvertently) and opportunistic infections such as mastitis and metritis occur with increased frequency in postpartum cows.

Year: 1999

description: The Animal Medicinal Drug Use Clarification Act (AMDUCA), which established conditions for legal extra-label use of approved drugs by licensed veterinarians, took effect December 9, 1996. The act recognized that veterinarians need to use drugs in an extra-label fashion to alleviate pain and suffering. It contains sufficient safeguards to protect public health and food safety. In December 1997 the Wisconsin Veterinary Medical Association (WVMA) executive board established a task force of 6 dairy practitioners, a University of Wisconsin veterinary clinician and pharmacist, 2 veterinary office practice managers, the WVMA office staff and the American Veterinary Medical Association (AVMA) staff person responsible for AMDUCA. The task force studied the act and gathered available information that would be needed by practitioners to comply. The focus of the task force was the adult dairy cow. While AMDUCA affects all species, concentrating on 1 species was more manageable. Dairy was chosen because of public health concerns about milk and dairy beef residues. Goals of the task force were: • gather available scientific information in 1 stand-alone report • organize withdrawal times on drug applications • develop prototypes of record systems • distribute the AMDUCA report to all dairy practitioners.

The fissures were partly synsedimentary and are often lined with stromatolite-like crusts. These crusts thus far are the only known subaerial Ordovician speleothems. They reach depths of up to 30 m below the former mound top. Macroscopically the crusts form decimetre-sized, cone-shaped domal aggregates, stalactites and stalagmites. Microfabric and morphology identify them as microbially mediated speleothems in a dark environment. Combined Sr and C isotope values indicate a formation of the speleothems from meteoric waters without influence of a significant soil horizon. For the first time the age of the speleothems can be precisely constrained by δ13C whole-rock and brachiopod shell isotope data to the mid-Hirnantian. Repeated and/or prolonged subaerial exposure of the Boda mud mounds during the Hirnantian is evident from karst surfaces and early cements in the mound capping carbonates. The speleothems and the karst surfaces record an estimated sea-level fall in the range of 80–130 m within the time window of the Hirnantian Isotopic Carbon Excursion. This massive regression coincides with maximum ice sheet extent inferred from sections in West Gondwana.

description: The impetus for considering pre-harvest efforts for shiga-toxigenic E. coli 0157 (sometimes termed E. coli O157:H7, and denoted in the remainder of this paper as simply 0157) has been the growing recognition that the risk of foodborne disease associated with 0157 cannot be eliminated at processing, retailing, or consumer levels. This has led to the multiple hurdles model (Figure 1) in which some reduction is made at each level. Since reductions are multiplicative, the overall effect is one of great reduction in risk.

description: Concerns about antimicrobial resistance have grown in recent years, becoming a truly global issue today. In addition, the antimicrobial issue is not limited to either the agricultural or human health care arenas. The World Health Organization has seated several consultancy groups to discuss the implications of antimicrobial use and resistance development. The National Academy of Sciences also has taken up the issue of antimicrobial use and resistance. Numerous other groups have held public and private meetings to discuss various aspects of antimicrobial resistance. Though there is little consensus regarding the roles of various antimicrobial use practices in the development of resistance that can impact public health, there is widespread recognition that the issue merits further study. There is a sense of urgency in our need for more data and information.

description: Antimicrobial resistance can be measured in the laboratory and can be suggested clinically in bacterial infections that fail to respond to antimicrobial therapy. A discussion of in vivo factors contributing to antimicrobial resistance is beyond the scope of this paper; however, a brief review of in vitro determination of antimicrobial resistance will be covered.

description: In LIAISON Work Package 4, 32 projects, networks or initiatives with co-creative and innovative characteristics were explored using ‘qualitative research’ methods such as in-depth interviews and focus groups. These methods helped to collect different opinions and experiences of people who were involved in the cases and they helped to understand how certain processes work and what aspects influence these processes. Therefore 30 European and 2 non-European cases were selected out of a pre-selection of 200 innovative cases using specific criteria to include the most insightful cases and to keep a balance in geographical distribution (in Europe), in funding sources (European funded, nationally funded, privately funded and even non funded), in sectors (agriculture, forestry and rural areas), in types of innovation, in amount of people participating directly and in types of cases (a project, a network, an initiative).

description: The members of this panel are Dr. Herb Lloyd of Belle Glade, Florida, who is a mixed practitioner and an Auburn graduate; Dr. Barry Allen, Rotan, Texas, who has a very mixed practice of cow-calf, dogs, cats, feedlot and everything else; and Dr. Robert Jackson, Lancaster, Wisconsin, who we had on the program here yesterday so I know you're all well acquainted with him. We will start this by having each man say a few words about his practice so that you will all get in your own mind what their problems are and then we will try to get a good question and answer session going. I would like to start out with Dr. Allen.

description: Objective: Our objective was to analyze and compare out-of-hospital cardiac arrest (OHCA) system of care performance and outcomes at the Medical Control Authority (MCA) level in the state of Michigan. We hypothesized that clinically and statistically significant variations in treatment and outcomes of OHCA exists within a single U.S. state. Methods: We performed a retrospective, observational study of all non-traumatic EMS-treated OHCA from the state of Michigan CARES registry for 2014–2015. Geocoding of the OHCA incident address was used to assign records to individual MCAs. MCA-based demographics, arrest characteristics, system of care performance and outcomes were quantified and compared. Associations between demographics, system of care parameters, and outcomes were examined at the MCA level. Results: A total of 8,115 records with complete data were available for analysis. Eleven MCAs met study inclusion criteria of >100 cases, producing a final sample size of 7,788 records (96%). Statistically significant variations in survival to hospital discharge ranged from 4.5% to 15% (p < 0.001) (Adjusted odds ratio [AOR] range 0.6–2.0) and survival with good neurologic outcome 2.7–12.5% (p < 0.001; AOR range 0.5–2.2,) were observed across MCAs. Bystander CPR ranged from 32% to 53% (p < 0.001) and bystander AED application ranged from 3.5% 11.5% (p < 0.05). Of patients admitted to the hospital alive, 29–68% received targeted temperature management. In hospital mortality ranged from 53.1% to 73.9% (p < 0.05). Conclusion: Significant intrastate variability in OHCA system of care performance and outcomes currently exist and are similar to what has been previously reported across North America almost a decade ago. This degree of variability highlights the opportunity to optimize modifiable factors within local systems of care to improve OHCA outcomes.
New insights into the genesis of the Miocene collapse structures of the island of Gozo (Malta, central Mediterranean Sea)

description: The large palaeosinkholes located in the NW of Gozo (central Mediterranean Sea, Malta) offer excellent exposures that provide information on the geometry and kinematics of large karst-related collapse structures. Detailed geological analysis of these peculiar palaeosinkholes indicates that deep-seated evaporite dissolution is the most feasible hypothesis to explain their formation, according to the following evidence. (1) Several structures have been formed by progressive foundering of cylindrical blocks with limited internal deformation as revealed by the synsedimentary subsidence recorded by their Miocene sedimentary fill. This subsidence mechanism is more compatible with interstratal dissolution of evaporites than karstification and cave development in limestone formations. (2) The dimensions and deformation style of the palaeosinkholes are similar to those of other collapse structures related to deep-seated dissolution of salt-bearing evaporites. (3) The arcuate monocline associated with some of these collapse structures is also a characteristic feature of subsidence related to dissolution of evaporites. However, no major evaporite formations have been documented so far in the subsurface of the Malta Platform.
