The Beef Industry in the 1990s
Creators: name: Thorpe, Topper
Publisher: name: American Association of Bovine Practitioners  Proceedings of the Annual Conference
Year: 1990

description: These are some of the most exciting and challenging times for cattlemen and those who provide services for, or supply products to them. It's a time filled with opportunity and pitfalls -- It all depends on how the situation is approached. Change is difficult for most of us who prefer to remain in our "comfortable rut". If we choose to remain in this rut, the world will probably pass us by -- But, if we're willing to get out of the rut we can find new opportunity. Factors influencing the changes being seen today - * Maturing of the meat industry * Declining cattle numbers * Excess capacity in feeding and packing * Increased competition for supplies * Narrower margins * Consolidation and integration All of these factors are forcing producers and processors to become more efficient, low cost producers, if they want to stay in business. A look at changes in the structure of the various beef producing and processing segments.

description: We point out that the initial-value (Cauchy) problem for self-interacting vector fields presents the same well-posedness issues as for first-order derivative self-interacting scalar fields (often referred to as $k$-essence). For the latter, suitable strategies have been employed in the last few years to successfully evolve the Cauchy problem at the level of the infrared theory, without the need for an explicit ultraviolet completion. We argue that the very same techniques can also be applied to self-interacting vector fields, avoiding a number of issues and "pathologies" recently found in the literature.

description: There is a growing concern about typically opaque decision-making with high-performance machine learning algorithms. Providing an explanation of the reasoning process in domain-specific terms can be crucial for adoption in risk-sensitive domains such as healthcare. We argue that machine learning algorithms should be interpretable by design and that the language in which these interpretations are expressed should be domain- and task-dependent. Consequently, we base our model's prediction on a family of user-defined and task-specific binary functions of the data, each having a clear interpretation to the end-user. We then minimize the expected number of queries needed for accurate prediction on any given input. As the solution is generally intractable, following prior work, we choose the queries sequentially based on information gain. However, in contrast to previous work, we need not assume the queries are conditionally independent. Instead, we leverage a stochastic generative model (VAE) and an MCMC algorithm (Unadjusted Langevin) to select the most informative query about the input based on previous query-answers. This enables the online determination of a query chain of whatever depth is required to resolve prediction ambiguities. Finally, experiments on vision and NLP tasks demonstrate the efficacy of our approach and its superiority over post-hoc explanations.

Publisher: name: American Association of Bovine Practitioners  Proceedings of the Annual Conference
Year: 1990

description: The implications of science and technology for society and government have grown enormously over the last few decades and will continue to do so. Geographical borders are less relevant today than locations and considerations of trading partners. The global economy has overshadowed any single national economy, and scientific and technical advances are leaving past animal health practices and policies obsolete. In many countries, animal agriculture is management of these risks within the framework of fair trade is inexorably forcing animal health officials and practitioners to reconsider past policies and programs, the methods of decision-making, legislative guidelines, and the delivery of services directed to animal health. Besides changes in global markets, new sensitivities and constituencies are developing that are profoundly influencing agricultural policy. Together, these issues are molding a new domestic policy that will evoke a new ethos and ethics in food animal agriculture and the veterinary profession. First, we will examine these contemporary issues in more depth. Then, we will consider how these issues affect our profession and you personally. Finally, we will look at prescriptions for change and how veterinary medicine collectively and you and I, personally, can consider appropriate strategies to be well positioned in the year 2000. The forces reshaping agriculture will continue to foster a climate of change and new opportunity for veterinary medicine. These major forces include new markets and trading partners, new constituents, changes in domestic policy, and changes in decision-makers, especially Congress. Now, and in the future, we will continue to face critical choices that will determine the future and quality of new services because of the strength of these forces. A new veterinary ethos and ethics is demanded.

description: We improve the current upper bound on the axion-photon coupling derived from stellar evolution using the $R_2$ parameter, the ratio of stellar populations on the Asymptotic Giant Branch to Horizontal Branch in Globular Clusters. We compare this with data from simulations using the stellar evolution code MESA which include the effects of axion production. Particular attention is given to quantifying in detail the effects of uncertainties on the $R$ and $R_2$ parameters due to the modelling of convective core boundaries. Using a semiconvective mixing scheme we constrain the axion-photon coupling to be $g_{aγγ} < 0.47 \times 10^{-10}~\mathrm{GeV}^{-1}$. This rules out new regions of QCD axion and axion-like particle parameter space. Complementary evidence from asteroseismology suggests that this could improve to as much as $g_{aγγ} < 0.34 \times 10^{-10}~\mathrm{GeV}^{-1}$ as the uncertainties surrounding mixing across convective boundaries are better understood.

Food Safety and the Food Animal Veterinarian

Publisher: name: American Association of Bovine Practitioners  Proceedings of the Annual Conference
Year: 1990

description: In a world of few certainties, one thing remains as a given. The food safety concerns of consumers, reflected in and fired by the media will not go away. No amount of science education and appropriate communication will blunt the contentions of consumer activist groups and the knee jerk, emotional reactions of state legislatures and our Congress. Example after example bears this out; Alar, DES, cranberries, sulfa in milk and hormones in beef. One has only to review the organic food section of the 1990 Farm Bill to recognize that the general public as expressed through the Congress wants its food supply to be free from chemical residues. A portion of the public is willing to pay more for food that is thought to be free of residues and/or grown naturally. This coalition of consumer activists, environmentalists, and natural food groups possesses sufficient power and appeal to ensure passage of organic labelling and production standards. The concerns about drug residues will not go away. We can't wish it away: we can't legislate it away: we can't educate it away.

description: Success in preventing infectious diseases requires a broad approach that considers all of the factors related to the onset, transmission and control of these diseases. Using this approach, a well designed prevention program encompasses all factors affecting resistance and all factors affecting exposure to the common bovine diseases. Programs based primarily on vaccines are most apt to fail and usually result in a poor rate of return on a significant investment. Effective programs are those based on a combination of sound management and sound medicine.

Bovine Abortion
Creators: name: Hurd, H. Scott
Publisher: name: American Association of Bovine Practitioners  Proceedings of the Annual Conference
Year: 1990

description: A farm in the Midwest is experiencing problems with abortion. This farm is milking around 80 cows, raises its own heifers at another place, and has a rolling herd average of 16,000 pounds. Heifers are bred with a bull at the other farm and brought to the milking farm 4 - 5 weeks before freshening. These springers are housed in the same area as the dry cows until approximately one week before freshening. All cows are vaccinated with a multivalent vaccine for Leptospirosis, Infectious Bovine Rhinotracheitis, and P13 at the time of dry off. Milking cows are fed a total mixed ration of corn silage, haylage, and high moisture corn. Dry cows and springers are fed corn silage with hay or green chop, depending on the time of year. On May 1 an aborted calf approximately 120 days gestational age was found in the freestall area. On June 1, one heifer aborted 2 weeks before her calving date. On June 10 another heifer aborted. The veterinarian was called out and he submitted serum samples from both heifers to the diagnostic lab, results were negative. A dry cow aborted on June 15. The fresh fetus and placenta were carried, by the producer, to the diagnostic lab. It will be 2 weeks before results are available. Another heifer and a cow had late term abortions on June 17 and 18. Another cow in the low group aborted twins on June 21. Immediate action is called for but no diagnosis can be made from the laboratory findings.

Diagnosing Viral Infections
Creators: name: Collins, James K.
Publisher: name: American Association of Bovine Practitioners  Proceedings of the Annual Conference
Year: 1990

description: This paper addresses some of the inherent limitations of detecting viral infections in cattle. It also addresses new diagnostic tests that offer significant practical advantages as well as increased sensitivity of virus detection. The methods presented have been selected from among many new methods that have been recently published and are continuing to be published at an increasing rate. At this time it is best to remark that most of the newer methods have great potential, but have not been subjected to enough field situations or animal specimens to predict future usefulness. In order for development and application of a truly useful test, the critical underlying assumptions necessary for successful diagnosis of bovine viral infections must be examined for their impact on diagnostic methods and diagnostic laboratories.

description: Transition metal dichalcogenides (TMD) monolayers, holding potential as good sunlight absorbers, are promising materials for next-generation optoelectronic devices. They may enable ultrathin photovoltaic(PV) devices thanks to their semiconducting character. In addition, heterocombinations of AlN and GaN sheets with MoS$_2$ monolayers have been suggested to be efficient water-splitting devices. Following these promising findings and motivated by the small lattice mismatch, we take up the idea of coupling a semiconducting WS$_2$ TMD monolayer with a AlN monolayer in a vdW heterostructure which is, as well, promising for photo-catalysis or photo-voltaic devices. We study this heterostructure by means of first principles calculations, and we show that many-body effects change the heterostructure band alignment from type II to I, demonstrating how their inclusion is compulsory for a correct prediction of the electronic and optical properties of 2D materials.
Rumen Function Enhancements

Publisher: name: American Association of Bovine Practitioners  Proceedings of the Annual Conference
Year: 1990

description: For years, ruminant nutritionists have utilized the rumen vat for one of its unique attributes - its ability to convert non-useable products into products of the nutritional value that enhances the growth of beef cattle, sheep and dairy cattle. Examples of this have been the utilization of fiber that is non-useable by humans or other non-ruminants. In addition, we have learned how the rumen converts urea to a useable form of dietary protein. In recent years the focus of ruminant research has shifted to the microbial population, and how altering microbial populations may fine-tune the nutritional diets utilized. Let's address three of these that currently are used: Ionophores, buffers and probiotics.

description: The price of feeds have increased significantly in the last few years. Farmers are continuing to try to find ways to cut feed costs. Several things have happened in ration formulation that are going to allow us to formulate rations less expensively. We are improving our knowledge on balancing for nonstructural carbohydrate, NDF, fat and protein fractions. This will allow us to improve our accuracy in formulating rations to optimize rumen fermentation and reduce the purchase of expensive protein and fat sources. The discussion of the protein system needs to be in terms of the carbohydrates consumed. We can then examine the opportunities to fine tune the protein fractions and save money.

Balancing Carbohydrates for High Producing Cows
Creators: name: Hutjens, Michael F.
Publisher: name: American Association of Bovine Practitioners  Proceedings of the Annual Conference
Year: 1990

description: With increasing milk production and emphasis on milk protein, meeting the nutrient needs of dairy cows is becoming a greater challenge. A balanced ration provides the correct amounts of nutrient for maximal microbial growth and end product yield (volatile fatty acids and microbial protein) plus undegraded nutrients (protein, carbohydrates, and fats) meeting the cow's productive needs (milk, growth, reproduction, and maintenance). Carbohydrates make up 70 percent of the ration and serve as the primary source of energy for lactating cows. This paper will discuss structural, non-structural, and functional carbohydrate components of the dairy ration (Table 1).

Microbiology and Physiology of the Rumen and Its Response to Different Feeding Strategies
Creators: name: Leedle, Jane A. Z.
Publisher: name: American Association of Bovine Practitioners  Proceedings of the Annual Conference
Year: 1990

description: The rumen is inhabited by a complex and highly competitive microbial population composed predominantly of strictly anaerobic bacteria (1010 to 1011/g ruminal contents) and protozoa (HP to 107/g) with smaller numbers (~104/g) of anaerobic fungi and facultatively anaerobic bacteria. These microorganisms are responsible for the degradation of ingested feedstuffs to fermentation acids (primarily the volatile fatty acids: acetate, propionate and butyrate) which are absorbed by the host through the ruminal epithelium and serve as the dominant carbon and energy sources for growth, maintenance and production. The ruminant animal then is a symbiotic association between mammal and microorganisms which evolved to enable the animal to live on high fiber diets (19). The ruminal regulatory systems developed by the animal were intended to cope with the microbial fermentation of forage-based rations and they operate very effectively for this purpose. These regulatory systems include temperature control, ruminal pH control through the buffering action of saliva, provision of extra nutrients such as urea or phosphate which enters the rumen also via the saliva, removal of inhibitory soluble (end) products through absorption, and removal of indigestible solids through passage to the lower tract (28). The animal can regulate the activities of the ruminal microorganisms only in so far as it can vary these processes. For the rest, the microorganisms are controlled only by the limitations of their growth physiology and by synergism and competition between species. With the practice of high grain feeding, the ruminal fermentation has become a liability to the host animal. When diets high in readily fermentable carbohydrates, i.e., diets high in starchy cereal grains, are fed to ruminants, caloric intake and substrate availability are no longer controlled by physical constraints such as fiber particle size and ruminal volume. The animal can now ingest more calories in a shorter time because of the smaller sized, energy-dense nature of cereal grains compared to cellulosic materials. As a result, members of the microbial community are released from substrate limitation restraints. For example, the activities of the amylolytic (starch-degrading) and the saccharolytic (sugar-degrading) bacteria are no longer limited by the relatively slow degradation of fibrous polymers to fermentable oligomers and thus starch degradation and fermentation can occur at very rapid rates.

Possibility of detecting gravity of an object frozen in a spatial superposition by the Zeno effect

description: While quantum probes surely feel gravity, no source of gravity has been prepared in a delocalized quantum state yet. Two basic questions need to be addressed: how to delocalize a mass sufficiently large to generate detectable gravity; and, once that state has been prepared, how to fight localization by decoherence. We propose to fight decoherence by freezing the source in the desired state through the Zeno effect. Successful implementation can be verified by scattering a probe in the effective potential generated by the source. Besides putting forward the idea, we provide an estimation of the values of the parameters required for the proposal to be feasible. Overall, the proposal seems as challenging as other existing ones, although the specific challenges are different (e.g. no entanglement needs to be preserved or detected, but the Zeno freezing must be implemented).

description: Compared to a single UAV with limited sensing coverage and communication capability, multi-UAV cooperation is able to provide more effective sensing and transmission (S&T) services. Nevertheless, most existing works on multi-UAV sensing mainly focus on mutually exclusive task allocation and independent data transmission, which did not fully exploit the benefit of multi-UAV sensing and communication. Motivated by this, we propose a novel multi-UAV cooperative S&T scheme with replicated sensing task allocation. Although replicated task allocation may sound counter-intuitive, it can actually foster cooperative transmission among multiple UAVs and thus reduce the overall sensing mission completion time. To obtain the optimal task allocation and transmit power of the proposed scheme, a mission completion time minimization problem is formulated. To solve this problem, a necessary condition for replicated sensing task allocation is derived. For the cases of replicated sensing, the considered problem is transformed into a monotonic optimization and is solved by the generic Polyblock algorithm. To efficiently evaluate the mission completion time in each iteration of the Polyblock algorithm, new auxiliary variables are introduced to decouple the otherwise sophisticated joint optimization of transmission time and power. While for the degenerated case of non-replicated sensing, the closed-form expression of the optimal transmission time is derived

description: In frustrated magnetic systems, the competition amongst interactions can introduce extremely high degeneracy and prevent the system from readily selecting a unique ground state. In such cases, the magnetic order is often exquisitely sensitive to the balance among the interactions, allowing tuning among novel magnetically ordered phases. In antlerite, Cu$_3$SO$_4$(OH)$_4$, Cu$^{2+}$ ($S=1/2$) quantum spins populate three-leg zigzag ladders in a highly frustrated quasi-one-dimensional structural motif. We demonstrate that at zero applied field, in addition to its recently reported low-temperature phase of coupled ferromagnetic and antiferromagnetic spin chains, this mineral hosts an incommensurate helical+cycloidal state, an idle-spin state, and a multiple-$q$ phase which is the magnetic analog of misfit crystal structures. The antiferromagnetic order on the central leg is reentrant. The high tunability of the magnetism in antlerite makes it a particularly promising platform for pursuing exotic magnetic order.

description: We report on a spin-orbit torque study of the spin current generation in Cr1-xPtx alloy, using the light 3d ferromagnetic Co as the spin current detector. We find that the dampinglike spin-orbit torque of Cr1-xPtx/Co bilayers can be enhanced by tuning the Cr concentration in the Cr1-xPtx layer, with a maximal value of 0.31 at the optimal composition of Cr0.2Pt0.8. We find that the spin current generation in the Cr1-xPtx alloy can be fully understood by the characteristic trade-off between the intrinsic spin Hall conductivity of Pt and the carrier lifetime in the dirty limit. We find no evidence for the spin current generation by other mechanisms in this material, revealing that the role of Cr is found to be simply the same as other metals and oxides in previous studies. This work also establishes the low-resistivity Cr0.2Pt0.8 as an energy-efficient spin-orbit torque provider for magnetic memory and computing technologies.

description: We consider a one-dimensional Brownian motion with diffusion coefficient $D$ in the presence of $n$ partially absorbing traps with intensity $β$, separated by a distance $L$ and evenly spaced around the initial position of the particle. We study the transport properties of the process conditioned to survive up to time $t$. We find that the surviving particle first diffuses normally, before it encounters the traps, then undergoes a period of transient anomalous diffusion, after which it reaches a final diffusive regime. The asymptotic regime is governed by an effective diffusion coefficient $D_\text{eff}$, which is induced by the trapping environment and is typically different from the original one. We show that when the number of traps is \emph{finite}, the environment enhances diffusion and induces an effective diffusion coefficient that is systematically equal to $D_\text{eff}=2D$, independently of the number of the traps, the trapping intensity $β$ and the distance $L$. On the contrary, when the number of traps is \emph{infinite}, we find that the environment inhibits diffusion with an effective diffusion coefficient that depends on the traps intensity $β$ and the distance $L$ through a non-trivial scaling function $D_\text{eff}=D \mathcal{F}(βL/D)$, for which we obtain a closed-form. Moreover, we provide a rejection-free algorithm to generate surviving trajectories by deriving an effective Langevin equation with an effective repulsive potential induced by the traps. Finally, we extend our results to other trapping environments.

description: In 2007, the Texas Higher Education Coordinating Board (THECB) funded 22 colleges to establish developmental summer bridge programs. Aimed at providing an alternative to traditional developmental education, these programs involve intensive remedial instruction in math, reading, and/or writing and college preparation content for students entering college with low basic skills. In 2009, the National Center for Postsecondary Research (NCPR) launched an evaluation of eight developmental summer bridge programs in Texas (seven at community colleges and one at an open-admissions four-year university), the early findings of which are described in this report. Students who participated in the study were randomly assigned to the program group or the control group. Program group students participated in the developmental summer bridge programs, while control group students received colleges’ regular services. All developmental summer bridge programs had four common features: accelerated instruction in math, reading, and/or writing; academic support; a “college knowledge” component; and the opportunity for participants to receive a $400 stipend.

description: Integrated Basic Education and Skills Training (I-BEST) integrates the teaching of basic skills and technical content in order to accelerate basic skills students’ transition into  and through a college-level occupational field of study.This innovative program model was developed by the Washington State Board for Community and Technical Colleges (SBCTC) in collaboration with the community and technical colleges in the state. At the time of our study, all 34 community and technical colleges in Washington State offered I-BEST programming in at least one workforce area, and there were approximately 150 approved I-BEST programs across the state. The study reported on here represents the final phase of a multi-year evaluation of the I-BEST model that began in 2009, conducted by CCRC in collaboration with the Washington SBCTC. Based on fieldwork undertaken in spring 2011 on 16 I-BEST programs at eight colleges, this report builds on CCRC’s earlier qualitative and quantitative research by seeking to understand those aspects of I-BEST that best support student learning, progression, and completion. In addition, the report considers the I-BEST student experience and evaluates the costs of I-BEST program delivery. The findings and recommendations highlighted below may be useful for funders, policymakers, and practitioners in other states who are considering transition interventions similar to the I-BEST model.

description: Each practice has its own personality or practice philosophy. Your practice philosophy is defined by the way you conduct your business on a day to day basis and not by what you might write in a manual. All veterinarians need to find their niche in a group practice... they need to feel that they contribute and are needed. If they do not find this niche, they are not likely to stay long.

description: "Local resetting" was recently introduced to describe stochastic resetting in interacting systems where particles independently try to reset to a common "origin". Our understanding of such systems, where the resetting process is itself affected by interactions, is still very limited. One ubiquitous constraint that is often imposed on the dynamics of interacting particles is geometric confinement, e.g. restricting rigid spherical particles to a channel so narrow that overtaking becomes difficult. We here explore the interplay between local resetting and geometric confinement in a system consisting of two species of diffusive particles: "bath" particles, and "tracers" which undergo local resetting. Mean-field analysis and numerical simulations show that the resetting tracers, whose stationary density profile exhibits a typical "tent-like" shape, imprint this shape onto the bath density profile. Upon varying the ratio of the degree of geometric confinement over particle diffusivity, the system is found to transition between two states. In one tracers expel bath particles away from the origin, while in the other they ensnare them instead. Between these two states, we find a special case where the mean field approximation becomes exact.

description: In dairy practice it is quite common to do surgical procedures in barns. One minor but definite problem we deal with is getting all the needed drugs and equipment into the barn where the surgery is to be performed. We now find that doctors prefer the cat carriers over the wooden cases, even though they don't hold quite as much. I have also used cardboard "banker's boxes" to carry the same equipment. These take up even less room in the truck, and carry everything I need as long as -I lay the bottles of scrub and alcohol down.

description: A direct electronics printing technique through atomized spraying for patterning room temperature liquid metal droplets on desired substrate surfaces is proposed and experimentally demonstrated for the first time. This method has generalized purpose and is highly flexible and capable of fabricating electronic components on any desired target objects, with either flat or rough surfaces, made of different materials, or different orientations from 1-D to 3-D geometrical configurations. With a pre-designed mask, the liquid metal ink can be directly deposited on the substrate to form various specific patterns which lead to the rapid prototyping of electronic devices. Further, extended printing strategies were also suggested to illustrate the adaptability of the method such that the natural porous structure can be adopted to offer an alternative way of making transparent conductive film with an optical transmittance of 47% and a sheet resistance of 5.167Ω/O. Different from the former direct writing technology where large surface tension and poor adhesion between the liquid metal and the substrate often impede the flexible printing process, the liquid metal here no longer needs to be pre-oxidized to guarantee its applicability on target substrates. One critical mechanism was found as that the atomized liquid metal microdroplets can be quickly oxidized in the air due to its large specific surface area, resulting in a significant increase of the adhesive capacity and thus firm deposition of the ink to the substrate. This study established a generalized way for pervasively and directly printing electronics on various substrates which are expected to be significant in a wide spectrum of electrical engineering areas.

description: We consider the extreme value statistics of centrally-biased random walks with asymptotically-zero drift in the ergodic regime. We fully characterize the asymptotic distribution of the maximum for this class of Markov chains lacking translational invariance, with a particular emphasis on the relation between the time scaling of the expected value of the maximum and the stationary distribution of the process.

description: The concept of alloying multiple principal elements at high concentrations has led to the development of High Entropy Alloys (HEAs) with exceptional mechanical properties, making them the focus of major recent scientific endeavors. Geometrically complex HEAs with tailored microstructural characteristics can be produced using additive manufacturing technologies such as powder bed fusion (PBF). However, an in-depth study on the effect of process thermal conditions during PBF is required to effectively fabricate HEAs with desirable mechanical characteristics. Thus, in our present molecular dynamic (MD) study we have explored the implication of PBF process thermal conditions on the mechanical characteristics of FeNiCrCoCu HEA by systematically varying laser scan speed from 0.4 Å/ps to 0.1 Å/ps, unidirectional and reversing laser passes from 1 to 4, and laser power from 100 microwatts to 220 microwatts. Our investigation suggests that reducing the laser scanning speed up to a critical velocity of 0.2 Å/ps considerably improves mechanical strengths, with further reduction creating severe surface defects. Decreased ultimate tensile strength (UTS) is associated with the annihilation of the bulk sessile dislocations during tensile straining marking an early yield failure. Alternately, the material's strength could be improved by annealing with several unidirectional laser passes over the same target region, resulting in enhanced UTS due to subtler yield points. Increasing laser power aids in ameliorating material density ultimately leading to higher UTS even in non-dislocation-free structures. These findings will assist researchers to understand the underlying effects and optimize process thermal parameters to fabricate superior HEAs utilizing additive manufacturing.
Nutritional and Management Considerations Associated with Pen Deaths

description: Death of cattle in the feedlot has caused the loss of countless dollars of potential profits annually by cattle feeders. Managers spend large amounts of their time and energy in an effort to decrease these losses in order to save this revenue for the feedyard and their customers. When viewed from an economic standpoint, a feedyard which will annually feed 60,000 head might have an average death loss from various causes of approximately one percent or about 600 head. If these cattle are fed on the average from 725 to 1100 lbs. their median weight would be equal to 912.5 lbs. for a total annual loss of 547,500 lbs. At an average selling price of $72.00 per hundredweight, this would equal a loss in equity of $394,200.00 This is in terms of average value of the cattle. Associated reduction in revenue would be the loss of the potential value of finished beef, loss of interest and veterinary expense, loss of potential feed sales and finally the decrease in profit potential by the cattle owner. Obviously the causes of death in feedlot cattle are numerous and difficult to predict. Realistically, every feedyard has or should have, some type of animal health program which it subscribes to for prevention and treatment, requiring considerable amounts of man-hours and drug expense annually. A large portion of morbidity and mortality in the feedyard is caused by shipping stress. Cattle, which are shipped long distances, have been subjected to excessive handling as well as environments rich in pathogenic organisms in the receiving and handling pens. Other stressors include withdrawal of feed and water, long periods without rest and finally subjection to diesel fumes while on the truck. Physiologically, these animals are tired, weakened and dehydrated, having lost substantial levels of vitamins and electrolytes while in transit. This produces an environment within the animal that is lower in immunological activity than that of nonstressed animals and is therefore perfect for the propagation of pathogens. This lowered resistance is enhanced by the co-mingling of cattle from various origins and the resulting subjection to infectious agents to which they may not have developed a natural immunity. These cattle are excellent candidates for any of the host of feedlot diseases commonly observed which ultimately result in death losses. Many times the feedyard manager implicates the consulting veterinarian and his health program for all death losses in the yard. While the veterinarian does have a large responsibility concerning newly received cattle as well as the overall health program in the yard, there are areas affecting cattle mortality where he has only limited impact.
