Decision making for sexed semen and beef semen in dairy production
Authors: Cabrera Victor E. , Li Manfei
Published: July 2023

Breeding strategies using sexed semen on younger and supe­rior animals and beef semen on older and inferior animals are becoming widely used in the dairy industry because it bal­ances the number of replacements produced and required while bringing extra income of selling crossbreed beef calves that are more valuable than dairy calves. The value proposition also implies genetic improvement because of greater breed­ing selection and shorter intergenerational interval, which can be captured in improved milk productivity. The best semen-type breeding strategy is farm specific and dependent on herd reproductive performance and ever-changing market condi­tions. Hence, the need to use models and projections to assert the optimal semen-type breeding strategy that optimizes the net return of each farm under specific market conditions. We analyzed the economic value of using alternative breeding strategies using sexed, beef and conventional semen using 2 ap­proaches. A short-term approach contained in a user-friendly decision support tool, the Premium Beef on Dairy Program, assessed the income from calves over semen costs over a breed­ing cycle whereas a long-term approach, using the Animal Life Cycle submodule of the Ruminant Farm Simulation Model, included additionally breeding, rearing and feed costs, and slaughter, heifer and milk sales revenues. Important in the long-term evaluation was the milk value change as a proxy for genetic improvement. Both approaches consistently pointed out that the advantage of the sexed/beef semen is positively related to herd reproductive performance. The greater the reproduc­tive performance the more the economic opportunity. With medium to high reproductive performance (above ~20% 21-d pregnancy rate), the Premium Beef on Dairy Program found the maximum income from calves over semen cost occurred when sexed semen was used in the first 2 heifer breedings and first and second lactation superior cows, while the rest of the heifer breedings were made with conventional semen and the rest of the cow breedings were made with beef semen. These results were consistent in the long-term analysis, which indi­cated that even a slightly more aggressive breeding approach using sexed semen in all heifer breedings resulted in the best net return in the long-term when the extra value of increased milk productivity became the most important economic factor. Although the short-term analysis did not include the herd dy­namics and milk changes, it still produced the right trend and directionality for decision making. The recommendation is to use the Premium Beef on Dairy user-friendly tool according to a herd’s reproductive performance and market conditions, and repeat the analysis constantly as the management and market circumstances change. When a deep and long-term analysis is necessary, the use of the Life Cycle Assessment submodule from the RuFaS is critical. Thus, both approaches are useful and complementary.
Resuscitation of the newborn calf
Authors: Smith Geof W.
Published: July 2023

A significant number of calves still die before or shortly after calving. Dystocia is a major risk factor and both veterinar­ians and producers need to be aware of how to identify signs of distress in newborn calves and how to help provide effective resuscitation. The main objectives are to 1) get the calf breath­ing; 2) support circulation; 3) make sure the calf is warm and 4) provide pain relief. This presentation will focus on how to iden­tify a calf that needs extra attention following birth and how to effectively triage calves and provide effective treatment to those that are good candidates for resuscitation.
My experience with the VMLRP and VSPG programs: They’re not trying to kill you… it just seems that way
Authors: Montgomery-Rodgers Lincoln , Ross Madeleine
Published: July 2023

Over the past 50 years, cattle prices have remained relatively stable and the cost of ordinary consumer goods has increased moderately, but the price of a veterinary education has skyrock­eted. The USDA’s Veterinary Medical Loan Repayment Program (VMLRP) and Veterinary Services Grant Program (VSGP) are well designed systems that incentivize veterinarians to practice food animal medicine in underserved, often rural, areas.

Pregnancy diagnosis in small ruminants
Authors: Roberts Jennifer
Published: July 2023

Pregnancy diagnosis in small ruminant species is crucial for the management of sheep and goats, particularly in commer­cial settings. There are many options for pregnancy diagnosis in these species, including ultrasonography and blood-based assays to detect pregnancy-associated glycoproteins. The meth­od used often depends on the availability of veterinary services to perform pregnancy diagnosis and the management goals of the herd or flock. Regardless of the method chosen, it should be economical for the producer, easily performed in field condi­tions, and highly accurate. Additional information on gestation­al age and fetal number allows for improved nutritional man­agement of the herd or flock to ensure adequate nutrition in the periparturient period to prevent metabolic disease such as pregnancy toxemia. Providing these diagnostic services can be an important source of revenue for the veterinarian while pro­viding invaluable information to aid small ruminant producers in improving profitability in their herds and flocks.
Mycoplasma bovis and Mannheimia haemolytica dynamics during acute bovine respiratory disease in feedlot cattle
Authors: Valeris-Chacin R. , Powledge S. , McAtee T. , Morley P. S. , Richeson J.
Published: July 2023

Mycoplasma bovis is a bacterium member of the family Myco­plasmataceae, characterized by a small genome, lack of cell wall, and high nutritional requirements for in vitro growth (Li et al., 2011; Parker et al., 2018; Dudek et al., 2020). Traditionally, M. bovis has been linked to chronic BRD cases and treatment failures (Booker et al., 2008; Hermeyer et al., 2012; Gershwin et al., 2015; Becker et al., 2020). Several virulence factors have been implicated in M. bovis ability to persist in the lungs of cat­tle with BRD, such as variable surface proteins (Vsp), adhesins, nucleases, H2O2 production and biofilm formation (Burki et al., 2015; Perez-Casal, 2020). Due to the difficulties of growing M. bovis in the lab, the inherent culture bias (Prakash et al., 2021) could have shaped our current knowledge of M. bovis in BRD.

Recent evidence has emerged linking M. bovis presence in the upper respiratory tract with acute BRD status (Timsit et al., 2018; Centeno-Martinez et al., 2022). However, the association between M. bovis and other BRD agents, especially Mannheim­ia haemolytica, over time remains unknown during the first month on the feedlot. A more comprehensive understanding of the dependencies among BRD pathogens over time will help develop new non-antibiotic control strategies and subsequently reduce the burden of BRD on beef cattle production. Therefore, this study aimed to evaluate the association of M. bovis and M. haemolytica during acute BRD in feedlot cattle.

Published: July 2023

Immediately following parturition, physiological demands for calcium increase substantially to support the onset of milk production. As a result, transitioning dairy cows may experi­ence subclinical hypocalcemia (SCH) at some point during early lactation. Cows respond to this homeostatic challenge dynamically, such that serum total calcium concentrations (tCa) at 1 and 4 days in milk (DIM) can be used to classify cows into 4 calcium dynamic groups: normocalcemic (NC: SCH at no DIM), transient (tSCH: SCH at 1 DIM only), delayed (dSCH: SCH at 4 DIM only) and persistent (pSCH: SCH at both 1 and 4 DIM). Identifying cows in the pSCH and dSCH groups is important clinically because these groups are at greater risk of adverse health events compared to the NC and tSCH cows. Our objective was to describe the temporal patterns of milk constituents for cows in each calcium group using Fourier-transform infrared (FTIR) spectroscopic analysis of milk samples. Additionally, we hoped to ascertain whether these methods might be valuable as a diagnostic tool for grouping cows based on calcium dynamics at a clinically useful timepoint.
Distal teat amputation in lactating dairy cows with injury to the distal teat and streak canal
Authors: Klostermann C. A. , Desrochers A. , Babkine M. , Fecteau G. , Nichols S.
Published: July 2023

When a streak canal injury occurs, there may be subtle or no external signs of damage. The first sign a producer notices is it takes longer for the injured quarter to empty or milk flow is im­paired during milking. Given that a dairy cow with 4 efficiently functioning teats is essential to dairy production systems, an economically feasible procedure, such as distal teat amputa­tion, to treat these injuries is necessary. The objectives of this study were to describe the distal teat amputation procedure and determine the short- and long-term outcomes of dairy cows treated with a distal teat amputation. The hypothesis is that dairy cows with internal damage to the streak canal and subse­quent difficulty milking will have improved milking efficiency with the machine following surgical treatment with a distal teat amputation.
Defining clinical diagnosis and treatment of puerperal metritis in dairy cows: A Scoping Review
Authors: Garzon A. , Habing G. , Lima F. , Silva-del-Rio N. , Samah F. , Pereira R.
Published: July 2023

Puerperal metritis (PM) is a common infectious disease in dairy cattle. Currently there are discrepancies between clinical case definitions within and between available peer-reviewed literature and on-farms practices. The inconsistent use of PM criteria across studies and on-farm practices can result in disparities related to recommendations for treating cows, af­fecting judicious use of antimicrobials. Our objective was to systematically review literature for clinical signs used as diag­nostic criteria for PM, including local (e.g., vaginal discharge) and systemic signs of infection (e.g., fever, drop in milk).

Authors: Megahed A. A. , Jones K. , Bisinotto R. S. , Pohler K. , Bittar J. H. J.
Published: July 2023

Monitoring circulating progesterone concentration (P4) is an important component of basic and applied reproduction re­search and clinical settings. Radioimmunoassay (RIA) is con­sidered the gold standard method for measuring P4 in cattle blood, but it generates radioactive waste, has low throughput, and requires licensed facilities. Immulite® 2000XPI (Siemens) is a fully automated immunoassay system marketed for human use to measure concentrations of different analytes including P4. Our objectives were therefore to: 1) validate cattle serum P4 measurement with the Immulite 2000XPI; 2) characterize the analytical performance of the Immulite 2000XPI P4 immunoas­say (IPI) across the reportable concentration range.

Authors: Cabrera C. , Diehl B. , Bittar J. H. J. , Jones K. , Lipori E. , Megahed A. A. , Rae O.
Published: July 2023

The Florida Native sheep (FNS) is recognized primarily due to their natural adaptation to harsh parasitic and environmen­tal conditions which allows them to thrive on minimal input from producers. FNS have been found to possess genetic re­sistance to gastrointestinal parasitism when compared with other breeds. In general, sheep profitable production requires effective reproductive management which in turn relies on a thorough characterization of key physiological reproductive parameters of the breed. Effective reproductive management will also aid in the conservation and propagation of this endan­gered native Florida breed. Nonetheless, in the scientific litera­ture, there is a lack of information regarding FNS reproductive characteristics. The present study aims to establish FNS female reproductive seasonality and age to puberty to improve produc­tion and management practices as well as contribute to long-term genetic improvement and preservation of the FNS breed.

Authors: Kumar Kuldeep , Rawat Pooja , Kaur Simrat , Singh Nirmal , Yadav Harlokesh Narayan , Singh Dhandeep , Jaggi Amteshwar Singh , Sethi Dimple
Published: July 2023

Valsartan is an orally active non-peptide angiotensin receptor antagonist, an effective
and well-tolerated anti-hypertensive drug. Besides its antihypertensive action, it has clinical
implications in many other disorders, like heart failure (HF), arrhythmia, chronic kidney disease
(CKD), diabetic complications (DM), atherosclerosis, etc. Besides angiotensin receptor blocking
activity, valsartan reduces circulating levels of biochemical markers, such as hs-CRP, which is
responsible for its anti-inflammatory and anti-oxidant activity. Moreover, valsartan also acts by
inhibiting or inducing various signalling pathways, such as inducing autophagy via the
AKT/mTOR/S6K pathway or inhibiting the TLR/NF-kB pathway. The current review exhaustively
discusses the therapeutic implications of valsartan with specific emphasis on the mechanism of
action in various disorders. The article provides a detailed spectrum of the therapeutic profile of
valsartan and will likely be very useful to researchers working in the relevant research areas.

Published: July 2023

Los cafeticultores mexicanos enfrentan desafíos complejos con una variedad de temas entrelazados. El presente trabajo es un acercamiento a la compleja red que forma su problemática. Se llevaron a cabo 10 talleres de diagnóstico participativo en los cuatro estados con mayor producción de café en México: Chiapas, Veracruz, Oaxaca y Puebla. Dichos talleres se realizaron en coordinación con ocho organizaciones y en ellos se contó con la presencia de 312 actores sociales. Se identificaron 22 problemas y 23 fortalezas, así como, las relaciones entre ellos. Todo ello se concentró en tres temas centrales: capacidad organizativa, conocimiento y valores éticos, en una red de alta complejidad que genera vulnerabilidad ante intervenciones externas negativas y propicia la migración de jóvenes y la degradación ambiental. En aras de potencializar sus fortalezas es posible mejorar la cultura cafetalera y, en particular, la producción y la comercialización del aromático. El trabajo teórico en torno al concepto de sustentabilidad posibilita reconocer el valor del conocimiento tradicional de campesinos e indígenas, así como de sus relaciones comunitarias de cooperación y economías que les permiten intercambios, pero que no tienen como objetivo central la acumulación de valor monetario, sino la satisfacción de las necesidades humanas, individuales y comunitarias. El resultado de la reflexión abona a la mejor comprensión de las prácticas sustentables en términos funcionales.

Improvement of Power Quality in Grid Connected Wind Energy System
Authors: Rani Sangam Uma , T Dr. Sukanth.
Published: July 2023

Abstract: This research covers industrial plant-connected wind turbine system control. An algorithm permits a control structure that uses a four-leg inverter linked to the grid to inject energy and operate as an active power filter, reducing load current disturbances and improving power quality. Algorithms enable this control structure. A four-wire system considers linear and nonlinear three-phase and single-phase loads. The utility-side controller supplies active and reactive power and adjusts for reactive, nonlinear, and unbalanced single- and intra-phase demands during wind turbine connection. Besides providing power, this is done. If there is no wind power, the controller uses the DC-link capacitor and grid-connected power converter to improve power quality. The proposed control structure is based on conservative power theory decompositions, which distinguishes it from previous techniques. This option separates the inverter control power and current references, giving a broad variety of adaptable, selective, and powerful functions. Real-time software benchmarking has tested the recommended control technique for comprehensive real-time implementation. The real-time simulator "FACTS" and the DSP microcontroller test and implement the control strategy in hardware-in-the-loop. These results confirmed our power quality improvement control, allowing us to omit passive filters. This created an electronic smart grid-based control system that was more efficient, adaptive, and reliable.
Good Corporate Governance, Intellectual Capital, And Operational Efficiency: Affect Company Value
Authors: Suzan Leny , Ardiansyah Dekri
Published: July 2023

Purpose: As the best measure of company health, companies that have gone public often try to increase shareholder value. One of them is the company value because it describes the condition of the company. This study attempts to find out how corporate governance, intellectual capital, and operational efficiency affect company value.
Methodology/approach: This study uses quantitative data from 15 companies in the IDX BUMN20 Stock Index for 2018–2021.
Findings: The research findings show that institutional ownership and intellectual capital significantly and beneficially affect company value. Meanwhile, independent commissioners, audit committees, managerial ownership, and operational efficiency have no visible impact. This shows how institutional ownership is a component that can improve performance through supervision. At the same time, intellectual capital management is proven to maximize the company's value.
Practical and Theoretical contribution/Originality: The implication is that companies that disclose intellectual capital and uphold institutional ownership will give a positive signal to investors in making investment decisions.
Research Limitation: Future studies may be useful to compare firm values during and after the COVID-19 pandemic by using the factors examined in this research to provide a specific picture of how investors respond to the two conditions and their relation to signal theory.

Published: July 2023

Indonesia’s coffee is a one of major export and contributes significantly that generate foreign exchange to the country’s economy. The quality and quantity of coffee production depend on various factors such as humidity, rain, and fungus that can cause rust diseases on coffee leaves. This disease can spread quickly and affect other coffee plants quality, leading to decreased production. To address this issue, the CNN method with the VGG-19 architecture model was utilized to identify coffee plant diseases using image data and the python programming language, which in previous studies used MATLAB as their platform. In addition, VGG-19 has a more profound learning feature than the method used in previous studies, AlexNet which makes the structure of VGG-19 more detailed. The dataset that use in this paper is Robusta Coffee Leaf Images Dataset which have three classes and with 1560 images data in total, but only used 100 images in each classes. The VGG-19 model attained a precision level of 90% when the evaluated using the testing data with ratio 80:20, which 80% is training data, and 20% is validation data as testing data. This paper employed 0.0001 learning rate, batch size 15, momentum 0.9, 12 training iteration, and RMSprop optimizer.

Assessment of Polylactide as Optical Material
Authors: Kesting Matthias , Meyer Jörg , Seide Gunnar
Published: July 2023

Due to environmental concerns, interest in bioplastics is rising. For
optical applications, materials have to meet high requirements.
Polylactide (PLA), a known bioplastic, is already applied in high tech
applications such as medicine. The material shows favorable optical
properties and excellent resistance against photodegradation. However,
the material turns hazy due to crystallization when exposed to
temperatures above 55-60 °C. This renders it useless for optical
applications. Clouding might be avoided by influencing PLA’s
crystallization behavior. In this critical review the broad use of PLA
is discussed. It is also shown, that currently no material is
commercially available that meets all requirements set while being
biodegradable and exclusively based on renewable feedstocks. Finally, an
overview of the current state in research is provided, considering
PLA-based materials with adapted crystallization behavior under the
aspect of transparency. At last, recommendations for the goal of
achieving highly sustainable PLA-based optical components are given.
Fuzzy-QFD approach for Innovation Project Assessment and Prioritisation to support the Decision-Making: Metal-Mechanical Industry evaluation case
Authors: Romano Matheus Kupka , Szejka Anderson , Loures Eduardo Rocha
Published: July 2023

The concept of innovation has increased importance in the industrial
environment to maintain a competitive advantage in the global market.
Thousand innovation projects are proposed daily to create or rethink new
or existing products. All this change directly impacts the whole
manufacturing system, supply chain, and deliverables. The
decision-making process to choose which innovation project will bring
better benefits or opportunities follows the criteria of the company’s
managers. However, the criteria are subjective or without relevant
information for a bold decision, leading to a wrong decision. Based on
this context, this research proposed a Fuzzy-QFD approach to assess and
prioritise innovation projects based on 40 criteria divided by faces of
innovation (desirability, technical feasibility, and economic
feasibility) and maturity levels (ideation, preparation, validation,
incubation). This approach was tested in two innovation projects in the
metal-mechanical industry to determine the priority between of them. As
a result, Project 01 has a higher maturity level than Project 02,
proving the benefit of the proposed approach to support the
decision-making process in a Metal-Mechanical industry.

Handgrip strength (HGS) is considered an essential marker of an individual's physical strength throughout life, especially of the upper limb and fine motor function. HGS is influenced by basic anthropometric determinants such as age, stature, and gender. The information about the differences in these anthropometric parameters in athletes as compared to non-athletes and the consequent influence on HGS is scarce. Investigations of the association between involvement in hand-related and non-hand-related sporting activities among different age groups of both sexes with HGS, particularly in a developing nation like Nigeria are scarce. This study aimed to investigate how anthropometric parameters of age, height, weight, and body mass index (BMI), affect handgrip strength and their association with sport-related parameters. A crosssectional study was conducted on 370 healthy Nigerians aged 17-40 years, from sports centres in Kwara state. Subjects were grouped into hand-athletes, non-hand-athletes, and a control group of non-athletes. A questionnaire was administered to get their biodata, while measurements of HGS(lbs); using a dynamometer, height(m), weight(kg), and BMI(kg/m2) were taken. HGS of hand-related athletes was significantly greater than the non-hand athletes and non-athletes. No significant difference was observed between the non-hand athletes and non-athletes. HGS of the non-sportsmen was significantly correlated with age, height, weight, and BMI, however, there were no significant correlations for non-sportswomen. HGS of the non-hand-sportsmen was significantly correlated with age, weight, and BMI, but not with height, while only BMI was significantly correlated for non-hand-sportswomen. HGS of both hand-sportsmen and hand sportswomen were significantly correlated with weight and BMI, however, age and height showed no significant correlation. A strong positive correlation exists between HGS and anthropometric parameters of weight and BMI in relation to hand-related sporting activities in both sexes, but not with age and height.

Equipment manufacturing involves the integration of multiple technologies and is a complex product system. In the independent innovation of complex product systems, product development is the most important way. Multi-objective cooperative control has been applied to various industries with remarkable results. In this paper, high quality research and development of complex products in equipment manufacturing industry is the main goal. Inspired by the dimensional parameters of the key structures of the product and the structure of the endocrine regulation network, a multi-objective collaborative controller consisting of a speed and position coordinator, a module consisting of a speed and position coordinator, a hormone discriminator, a hormone optimizer, and a controller is designed. The data from the cooperative control study shows that when the controller parameters [3, 1, 2] are used, the velocity parameter is 0.7, the differential parameter is 0.04, and the controller output parameter is 0.8. The force control parameter is 2, the differential parameter is 0.05, and the controller output parameter is 0.7.

Published: July 2023

The special operation mode of high-speed railway will generate a large amount of harmonics. The harmonics will be transmitted to the 220kV side high-voltage cables through the traction transformer, and harmonic voltages will be generated on the cable sheath, threatening the safe operation of the cables. In this paper, on the basis of the measured harmonic data of the traction substation, a harmonic source model based on the measured data is established, which solves the complex problem of harmonic source modeling and can accurately reflect the actual operating conditions of high-speed trains. On this basis, the harmonic voltage characteristics of the cable sheath on the 220kV side of the high-speed railway under the three working conditions of traction, regenerative braking and inertia are simulated and calculated, and the effects of cable length, cable grounding method, and harmonic current parameters on the harmonic voltage are explored. Affect the law. The results show that under different operation modes of high-speed rail, the harmonic voltage of the sheath far exceeds the normal operation of the power frequency, and the maximum value of the harmonic voltage of the cable sheath can reach 454V under the traction condition; Under working conditions, the overvoltage of the metal sheath is greatly affected by the grounding method of the cable, the length of the cable and the harmonic current content. The above research results have important reference significance for the safe operation of electrified railways.
Application of Natural Language Processing-based Emotional Semantic Analysis in the “One Core, Three Integrations” Vocal Music Teaching Model
Authors: Shan Jie
Published: July 2023

To be able to better improve musical literacy and artistic aesthetics, this paper presents a study on the application of sentiment analysis for vocal music teaching under natural language processing. Firstly, for the training text that has been labeled with categories, a suitable classification model is built for the unlabeled test text using the model category prediction. The sum of the identified sentiment scores is calculated, and the different results are compared to set a reasonable threshold to determine the sentiment polarity. According to the mutual information statistic value of each feature item, the feature items with a mutual information statistic value higher than the threshold are retained. The weights of each feature term are normalized to the interval to which the range of weights is normalized, and the feature weights are obtained. The optimal classification surface is calculated by converting the Lagrangian optimization method into a problem of finding the pair, which makes the low-dimensional problem transformed into a high-dimensional space and combines the advantages of Bayes’ ability to automatically adjust the weight coefficients in training and the huge training capacity of neural networks to improve the flexibility and robustness of the training model. Feature extraction is performed by convolutional layers, and the dimensionality of the feature vector is reduced by the maximum pooling method to realize an emotional-semantic vocal teaching model. The results show that the proposed method can improve the flexibility and accuracy of the semantic analysis model, and also enhance the training robustness of the network, with the F1 value reaching 91.65%, which can accurately mine the application data of “one core and three integrations” vocal teaching model and improve the teaching model in universities.

With the gradual deepening of power-related research and the expansion of power data volume, power data-oriented research and applications have fully entered the era of big data and cloud storage. The huge amount of heterogeneous data samples also bring a huge impact on traditional data processing methods. Therefore, let each virtual power plant participate in the electricity market externally as a unified power plant, and build a blockchain structure of multiple virtual power plants in the form of a slice. The structured data such as the basic information of the account is stored in the enterprise database in a relational data model and managed through an identity verification policy. The mechanism of off-chain negotiation and on-chain settlement is used to manage the transaction data. The management mechanism is further improved by combining an encryption scheme and a security evaluation method. After the practical test of the management mechanism, the time consumed for one and two parallel operations reaches 23 seconds and 8 seconds, and 4 seconds and 9 seconds or less for three and four times, respectively. In the case of nine users’ data distortion, the root means the square value of the blockchain data management mechanism is only 0.82, which is significantly less than 1. It shows that the blockchain-based data management mechanism, as a new generation of power data management means, can not only effectively integrate the power grid information data and relieve the pressure of the power grid system, but also avoid data leakage and strengthen power security.
