Animal health: keystone in the sustainability and competitiveness of the livestock sector
Authors: Torres Medina Alfonso
Published: August 2024

Summary The rapid expansion of human population in the world, combined with enhanced economic capacity of developing nations, is resulting in an unprecedented demand for meat production with increased competition for land water and energy, requiring enhancements in the sustainability of livestock practices. At the same time, globalization of world economies is creating challenges and opportunities to the livestock sector to be more competitive in regional, national and international markets. Animal health is critical for the sustainability of the livestock sector. Unthrifty animals cannot reach their genetic potential for productivity requiring more inputs of land, energy and water for the same amount of product output. The impact of poor animal health goes beyond the decrease sustainability of the livestock sector, but affects also wildlife conservation and exacerbates poverty as low-income populations divert on subsistence from bush meats. In the same way that poor health affects the sustainability of livestock production, poor animal health significantly affects the competitiveness of the livestock sector. Due to mortality and/or chronic morbidities, unhealthy livestock industries lead to less quantity and quality products reaching the local and national markets with little or no opportunities of profiting from the benefits of international trade. Resumen La rápida expansión de la población humana en el mundo, junto con la mejora de la capacidad económica de las naciones en desarrollo, está dando lugar a una demanda sin precedentes de la producción de carne con el aumento de la competencia por agua, tierra y energía, lo que requiere mejoras en la sostenibilidad de las prácticas ganaderas. Al mismo tiempo, la globalización de la economía mundial plantea desafíos y oportunidades para el sector ganadero para ser más competitivos en los mercados regionales, nacionales e internacionales. La sanidad animal es fundamental para la sostenibilidad del sector pecuario. Animales insalubres no pueden alcanzar su potencial genético de productividad requiriendo más insumos de tierra, agua y energía para la misma cantidad de producción. El impacto de las deficiencias en salud animal van más allá de la disminución de la sostenibilidad del sector pecuario, pero también afecta a la conservación de la vida silvestre y exacerba la pobreza ya que las subsistencia de poblaciones de bajos ingresos dependen en un mayor grado de las carnes de monte. De la misma manera que deficiencias en la salud afectan la sostenibilidad de la producción animal, una salud animal deficiente afecta de manera significativa la competitividad del sector pecuario. Debido a la mortalidad y / o morbilidad crónica animal el sector pecuario produce una menor cantidad y calidad de productos dirigidos a los mercados locales y nacionales, con poca o ninguna oportunidad de sacar provecho de los beneficios del comercio internacional.
Métodos de avaliação e estratégias de mitigação de metano entérico em ruminantes
Authors: Ribeiro Pereira Luiz Gustavo
Published: August 2024

Summary Latin America livestock industries have been especially criticised because of their large greenhouse gas production as a result of the use of degraded forages and performances below production potential. Agriculture contributes a significant amount of the three main greenhouse gases: methane (CH4), carbon dioxide (CO2) and nitrous oxide (N2O). Methane gas has a global warming potential 25 times greater than CO2. Enteric methane is an important greenhouse gas which is responsible for approximately 15% of global warming. The tendency and legal necessity to mitigate the greenhouse gas emissions is likely to have a direct influence on the increased efficiency of livestock systems, including animal nutrition and handling. The development of mitigation strategies and the viability of the strategies' practical applications are issues that have been researched around the world. There are various nutritional strategies to mitigate enteric methane that have been studied and developed. All of these have different viabilities, costs and possibilities to be accepted by the producers. The choice of which one will be adopted should be based on the capacity to reduce methane emissions associated with economical viability and the maintenance of animal performance. The increase in zootechnial parameters that will be achieved in production systems (mainly the ones related to efficient forage use) associated with good nutritional, health and reproductive management are important strategies to consolidate Brazil as a food producer to the world, respecting the demands related to the land, water, conservation of biodiversity and the emission of greenhouse gases. Key words: climate change, greenhouse gas, livestock, methane, sustainability.

Published: August 2024

Background: litter provides comfort to animals while improving productive performance and carcass quality. Objective: this study evaluated broiler performance, incidence of contact dermatitis, and quality of poultry litter of wood shavings and/or sugarcane bagasse (SB) after five consecutive flocks. Methods: two thousand birds were raised in five consecutive flocks composed of 400 chicks each. The experiment was set in a completely randomized design with five treatments and four repetitions. The treatments consisted of substituting wood shavings with different levels of SB (0, 25, 50, 75, and 100%). Results: litter density, pH, dry matter content, total nitrogen, and phosphorus did not vary between treatments. However, substituting wood shavings with SB increased moisture retention capacity of the litter and ammonia production. Neither carcass lesions nor productive performance, with the exception of weight gain and feed conversion ratio in the fifth flock, differed between treatments. Conclusions: substituting 75% of wood shavings with SB maintained litter quality and improved poultry performance.

Published: August 2024

Background: flavophospholipol is an antibiotic growth promoter (AGP). The current ban of AGP in some countries is controversial because their benefits on the environment and economy by saving feed and reducing nitrogen excretion have been overlooked. White button mushrooms have important nutritional properties and the industry discards large quantities of waste that could be fed to animals. Objective: to evaluate the effect of dietary inclusion of five levels of edible mushroom powder (EMP) and flavophospholipol on the performance and blood serum metabolites of broilers. Methods: a total of 300 one-day-old male broiler chicks were randomly distributed into 10 treatments with three replicates of 10 chicks per pen. The experiment consisted of a factorial arrangement (2x5 treatments) with five inclusion levels of EMP supplementation (0, 0.5, 1.0, 1.5, and 2.0 g/kg of diet) and the addition of 0 or 5 mg/kg of flavophospholipol. Results: supplementation with EMP and flavophospholipol, as individual factors, had a negative effect on feed intake, but positively affected broiler weight gains and feed conversion ratio. Antibiotic supplementation increased uric acid concentration and, as an interaction with mushroom powder, reduced serum triglycerides, and very low density lipoprotein cholesterol (VLDL). The EMP also affected serum concentration of total cholesterol. Conclusion: the two substances studied, but not their combination, had a positive effect on growth performance of chickens that could be translated into economic benefits.

Background. Nowadays, interest in studying the local anomalous magnetic field to solve the problems of oil and gas geology is growing, and the capabilities of the equipment can significantly increase the speed, accuracy and detail of work. Accordingly, the development and testing of an improved method of detailed magnetic recording in motion becomes relevant. Methods. For areas with low gradient magnetic field, we assessed the accuracy of the survey by comparing the maps obtained from repeated surveys of the site. Results. The survey of the magnetic field was conducted in the movement. The total surveyed area was about 20 square kilometers in the Zinkovsky district of the Poltava region. The inter-profile distance was about 50 meters, the distance between the points of observation on the profile was about 1 meter. This grid of observations allows us to get maps that differ significantly from the maps obtained by the usual density of observations. This technique also allows identifying local anomalies, and drawing conclusions about the fine structure of the magnetic field. The main objects that form anomalies and their geological characteristics are identified. On this basis, interpreted magnetic field anomalies in oil and gas regions were catalogued. Conclusions. We have proposed explanation of tectonic and geochemical factors, which form local anomalies of the magnetic field of the studied areas. Three types of anomalies associated with ravines are distinguished. Positive anomalies over ravines and step-type anomalies, in our opinion, are associated with tectonic movements, and negative anomalies are due to slope wash processes. Alternating magnetic fields in the studied areas may be due to ferruginized deposits.

Published: August 2024

Syngnathia is an extremely rare condition with a congenital fusion of the maxilla and mandible described as an occlusion of the oral cavity opening. No case of complete bony synostosis, identified in the new-born period have survived beyond few months of age, hence making this case a novel addition to literature. Here we present a case of a term neonate with fused maxillo-mandibular jaws and synechial closure of the mouth with subtle dysmorphic features. Respiratory distress and feeding issues remained the most important challenges. Investigations with baseline radiography, a 3D CT reconstruction of the head, face and neck anatomy elucidated bilateral bony fusion of maxillomandibular jaws, a midline cleft in the soft palate and micro-glossia. After initial stabilisation, surgical intervention was done in two graded phases. First, an orifice was established to enable an airway route, in an anticipation of difficult airway in an event of distress followed by major synechiae and bony excision with placement of an oral distractor and exteriorisation of the small tongue. With multi-disciplinary team effort and physio-motor stimulation, she was established on direct breast feeding by 37 days of life. She was developmentally normal at 7 months of age with decent growth.

Spinal cord compression (SCC) is a critical medical condition characterized by pressure on the spinal cord, which can lead to severe and potentially irreversible neurological damage if not promptly addressed. The causes of SCC are varied, including primary and metastatic tumors, traumatic injuries, degenerative diseases, and infections. Early detection of SCC is paramount for improving patient outcomes, minimizing risk of permanent deficits, and enhancing quality of life. This review examines etiology and clinical presentation of SCC, highlighting the significance of early screening and detection. Effective screening involves identifying high-risk individuals through risk stratification, utilizing advanced imaging techniques such as magnetic resonance imaging (MRI) and computed tomography (CT) scans, and maintaining clinical vigilance. Recognizing early symptoms, such as localized pain, neurological deficits, and autonomic dysfunction, is crucial for timely intervention. Prognosis of SCC improves significantly with early diagnosis and intervention. Treatment options include surgical decompression to relieve pressure, radiation therapy for tumor-related compression, and corticosteroids to reduce inflammation. Early intervention can prevent irreversible neurological damage and enhance recovery potential. Comprehensive rehabilitation, involving physical and occupational therapy, is critical for restoring function and improving quality of life.

Published: August 2024

Heavy metal (HM) stress is one of the most important abiotic stresses affecting flora and fauna worldwide due to a rapid global increase in the urbanization and industrialization and the consequent rise of HM concentration in the atmosphere. Typically, plants have distinct mechanisms to cope up with HM stress. These mechanisms rendering tolerance to the plants by detoxifying the HMs. Additionally, a number of physiological and molecular changes occur in plant cells due to their exposure to HMs. This culminates in the generation of reactive oxygen species (ROS) that cause oxidative stress in plants, which significantly affects plant metabolism and disrupts normal vital cellular functions. However, in order to cope with such stresses, plants possess a strong antioxidant defence system to counteract increases in the ROS-induced stress. The enzymatic components of this system include superoxide dismutase (SOD), catalase (CAT), ascorbate peroxidase (APX), monodehydroascorbate reductase (MDHAR), dehydroascorbate reductase (DHAR) and glutathione reductase (GR). The non-enzymatic components are ascorbate, glutathione and phenolic compounds along with lipid-soluble molecules such as carotenoids and tocopherols. This review makes an effort to collect and collate the currently available information on metal stress and cellular antioxidant systems of plants, emphasizing upon the role of enzymatic and non-enzymatic mechanisms for detoxification of HM-induced oxidative stress.

Authors: Çetin Selim , Can Erkan
Published: August 2024

The isomorphism theorems for crossed squares of commutative algebras, which arise when the crossed modules of algebras are given an extra dimension, are the main subject of this paper. The definition of crossed squares of commutative algebras is given in this context, encompassing ideas like the crossed square ideal, image, and quotient crossed squares, as well as the kernel for crossed square morphisms. The study discusses the way how isomorphism theorems are applied to these structures and offers detailed proofs for this framework. Moreover, some necessary concepts such as quotient crossed squares, which were not previously specified in these structures, are also presented, and some basic properties are examined. The study provides opportunities for possible generalization to a number of different structures, including crossed n-cubes.
A low-voltage, high-performing CMOS transistor based on multiple- output operation transconductance amplifier for current mode KHN Universal filter applications
Authors: Demirel Huseyin
Published: August 2024

This study proposes a current-mode KHN universal filter design that can perform three standard functions simultaneously: low-pass, high-pass, and band-pass. The circuit is built around a multiple-output operation transconductance amplifier (MO-OTA), which allows for electronically adjustable pole frequency and quality factor by modifying input bias currents (IB). The circuit layout is straightforward, with two MO-OTAs and two grounded capacitors, eliminating the need for external resistors and depending entirely on grounded components. Because of its simplicity, the circuit is suited for use in a tiny, efficient design. The proposed circuit's operation was validated using LT-Spice simulations, and the results were in line with theoretical expectations. The circuit used around 298μW of power at ±0.2V power supply voltages. These results demonstrate the circuit's potential for low-power applications, which are crucial in many modern electronic devices. The suggested current-mode KHN universal filter offers a viable option for combining various filter functions in a single circuit with customizable parameters. Its simplicity, efficiency, and performance qualities make it a feasible choice for incorporation into a variety of electronic systems, allowing for more filter design freedom.

LOS POSTULADOS DE HANS KELSEN Y SU RELACIÓN CON EL ACCESO A LA JUSTICIA EN MÉXICO
Authors: TAPIA CHÁVEZ CHRISTIAN MIGUEL
Published: August 2024

Dentro del contexto jurídico de la justicia la solemos denominar como “dar a cada uno lo suyo” como bien refería el jurista Ulpiano, sin embargo, la eterna pregunta de concebir; ¿qué es la justicia?, se remonta desde siglos antes cuando autores como Aristóteles, Platón y en nuestro caso particular Kelsen conceptualizaban el origen, la naturaleza jurídica de la justicia y como debe entenderse, razón por la cual, esta investigación tiene como objetivo demostrar la relación entre la teorías de la justicia de Hans Kelsen en relación con el derecho positivo y el acceso a la justicia en México, desde el análisis de diferentes vertientes como la teórica, jurídica y constitucional en el Estado. Por ello en la presente investigación hicimos uso de los métodos deductivo y cualitativo con un enfoque jurídico legal, que nos permite visualizar la existencia y el acceso de dicho derecho humano en el marco normativo mexicano.
Within the legal context of justice we usually refer to it as "giving to each his own" as the jurist Ulpian referred, however, the eternal question of conceiving; However, the eternal question of conceiving what justice is goes back centuries before when authors such as Aristoteles, Platon and in our particular case Kelsen conceptualized the origin, the legal nature of justice and how it should be understood, which is why this research aims to demonstrate the relationship between Hans Kelsen's theories of justice in relation to positive law and access to justice in Mexico, from the analysis of different aspects such as theoretical, legal and constitutional in the State. Therefore, in this research we made use of deductive and qualitative methods with a legal-legal approach, which allows us to visualize the existence and access of this human right in the Mexican regulatory framework.

Published: August 2024

Beden perküsyonu olarak da bilinen beden müziği, bedenin çeşitli yerlerini bir çalgı gibi kullanarak bilinçli bir şekilde elde edilen seslerin ve hareketlerin bütünü olarak tanımlanabilmektedir. Orff ve Dalcroze gibi müzik eğitimi yaklaşımlarında hareket ve müzik birlikte kullanılmakta, okullarda uygulamaları yapılmaktadır. Ancak beden perküsyonu uygulaması yapan öğrencilerin bu uygulama hakkında nasıl bir algıya sahip olduğu merak konusu olmuştur. Dolayısıyla ortaokul ve lise kademesinde öğrenim gören 11-15 yaş arası öğrencilerin müzik derslerinde uyguladıkları beden perküsyonuna yönelik algılarının metaforik olarak incelenmesi bu çalışmanın konusunu oluşturur. Fenomenoloji (olgu bilim) desenine dayanan araştırmanın örneklemini, özel bir okulda öğrenim gören ve müzik derslerinde beden perküsyonu çalışmaları yapan 120 öğrenci oluşturmaktadır. Veri toplayabilmek amacıyla “Beden perküsyonu ... gibidir/benzer. Çünkü ...” cümlelerinden oluşan bir metafor formu hazırlanmış ve öğrencilerden boşlukları doldurmaları istenmiştir. İçerik analizi yapılarak incelen metaforlar 14 farklı kategoride toplanmış kavramsal olarak ortak özelliklerine göre beş farklı tema altında birleştirilmiştir. Miles ve Huberman testi sonucundan %90 oranında güvenilir bir analiz yapılmıştır. Bulgulara göre öğrenciler beden perküsyonunu %34 oranında “Olumlu bir duygu durumu “olarak “Eğlenceli, Başarılı Hissettiren ve Rahatlatan” şeklinde algılamaktadırlar. Öğrenciler aynı zamanda beden perküsyonunu %23 oranında “Olumsuz bir duygu durumu” olarak “Sıkıcı, Can yakan ve Yorucu” şeklinde algılamaktadırlar. Elde edilen bulgular doğrultusunda sayısal değerler incelendiğinde öğrencilerin beden perküsyonunu olumlu bir duygu durumu olarak algıladıkları söylenebilir. Sonuç itibarıyla gelecekte yapılacak araştırmalara ışık tutabileceği düşünülen bu çalışmanın daha geniş kapsamlı bir örneklem ve farklı araştırma desenleri kullanılarak farklı özellikteki örneklem gruplarıyla da yapılmasının yararlı olacağı düşünülmektedir.

The slow oxygen evolution kinetics of iron oxide nanorod arrays have limited their applications in photocatalytic water splitting. Herein, we introduce p-type semiconductor cuprous oxide and further cover cobalt hydroxide ultrathin nanosheets on the surface of both by electrochemical deposition; these methods obviously enhanced the photoelectrochemical (PEC) water splitting performance of iron oxide nanorods on titanium sheet substrate. The photocurrent of this heterostructure reached 4.8 mA/cm2 at 1.23 V (vs. reversible hydrogen electrode) in a 1 M KOH aqueous solution under AM 1.5G illumination, which is much higher than the currently reported photocatalytic water splitting performance of iron oxide nanoarrays. The construction of Fe2O3/Cu2S p-n heterojunction accelerates the separation of photogenerated carriers in the main body of Fe2O3 nanorod arrays; as an excellent oxygen evolution catalyst (OEC), the introduction of Co(OH)x accelerates the kinetic process of interfacial water oxidation leading to the rapid depletion of photogenerated holes, which further improves the charge separation on the photoanode surface. Thus, the synergistic effect between Fe2O3/Cu2S p-n heterojunctions and oxygen evolution catalysts enhanced the iron oxide nanorod array photoanodes.

Ikan nilem (Osteochilus hasselti) merupakan salah satu jenis ikan dari Family Cyprinidae yang hidup di air tawar dan banyak dibudidayakan di Indonesia. Pertumbuhan ikan nilem gunung yang lebih lambat dan warna tubuh yang mencolok dibandingkan ikan nilem jenis lain membuat ikan ini semakin jarang dibudidayakan. Hal tersebut membuat ikan ini semakin sulit diperoleh. Budidaya tunggal kelamin (monosex) menjadi salah satu alternatif untuk meningkatkan produksi dan dapat digunakan sebagai upaya pelestariannya. Kegiatan tersebut memerlukan pengetahuan jenis kelamin sejak ukuran benih, karena tidak semua spesies ikan memiliki seksual dimorfisme. Tujuan dari penelitian ini untuk mengetahui apakah karakter morfologi, meristik, dan truss morphometrics dapat digunakan untuk membedakan jenis kelamin benih ikan nilem gunung serta karakter spesifik apa yang dapat membedakan benih ikan nilem gunung jantan dan betina. Metode yang digunakan adalah metode survei dengan pengambilan sampel purposive random sampling. Sampel yang diambil sebanyak 55 ekor. Sampel yang didapatkan diamati performa morfologi, meristik, dan truss morphometrics. Data performa morfologi dan meristik yang diperoleh dianalisis secara deskriptif, sementara data hasil pengukuran truss morphometric diubah menjadi nilai rasio yang dibagi dengan panjang standar kemudian dianalisis menggunakan SPSS dengan uji Mann Whitney. Hasil dari pengamatan performa morfologi dan meristik tidak menunjukkan adanya perbedaan jenis kelamin benih ikan nilem gunung, sementara hasil pengukuran truss morphometrics menunjukkan bahwa terdapat satu karakter truss yang membedakan antara benih ikan nilem gunung jantan dan betina yaitu pada jarak D4 (pangkal sirip ekor bagian atas-pangkal sirip ekor bagian bawah) atau tinggi pangkal ekor. Berdasarkan hasil rata-rata pengukuran truss morphometrics pada jarak D4, didapatkan bahwa jarak D4 pada benih ikan nilem gunung betina lebih tinggi daripada benih ikan nilem gunung jantan.
