Tracing culinary practices in the western provinces of the Roman Empire using Organic Residue Analysis

This study aims at reconstructing foodways in the north-east (NE) of the Iberian Peninsula, focusing on lipid residue analysis of utilitarian vessels and using as case studies the sites of Puig Castellar of Biosca (180–120 BCE) and Guissona (120 BCE-third century CE). In total, fifty vessel fragments of different types and origins were analysed with techniques such as gas chromatography-mass spectrometry (GC-MS) and gas chromatography-combustion-isotope ratio mass spectrometry (GC-C-IRMS). As some vessel fragments were recovered from waterlogged contexts, they had excellent lipid preservation, which enabled the detection of various compounds that are rarely reported in archaeological contexts in Iberia. Analyses revealed both animal and plant products in the vessels, suggested that a variety of food resources was consumed, and that vessels had multiple uses. The detection of levoglucosan in some extracts, along with other heat markers, further suggested the presence of cellulose or starchy products in contact with fire as well as the heating of animal fats. Combined with available bioarchaeological and palaeoenvironmental studies from both sites, the analyses indicated a continuity in diet across the time periods during which the sites were occupied. Some differences were also observed, including the possible use of tubers until the first century CE. The results are then contextualised and compared with other available organic residue studies from the Roman Iberian Peninsula. The study demonstrates how the combination of multiple bioarchaeological proxies and biomolecular approaches can provide a holistic means to approach Roman foodways.

Prevalence of vitamin B 12 deficiency and associated factors among primary school children: North East Ethiopia: multicenter cross-sectional study

BackgroundThe prevalence of Vitamin B12 deficiency is common and is more frequent in low- and middle-income countries with a poor or inadequate diet of animal foods. In Ethiopia, researches related to the status of micronutrients in children are limited. Therefore, this study aimed to assess the prevalence of vitamin B12 deficiency and associated factors among primary school children.MethodsA cross-sectional study design was conducted from January 10-February 30/2023. A total of 514 students were selected using a systematic random sampling technique. Face-to-face interviews using a structured questionnaire, document review, anthropometric measurement, and laboratory studies were implemented to collect data. Data was analyzed by STATA version 14 and summarized by using frequency tables and graphs. Logistic regression analysis was done to identify factors associated with vitamin B12 Deficiency.ResultsAbout 34% of the students were found to have vitamin B12 deficiency. Not Consuming animal products (AOR = 1.83, 95% CI:1.20–2.79) and low body mass index (AOR = 1.62, 95% CI:1.05–2.47) were associated with vitamin B12 deficiency.ConclusionsThe study revealed a notable high deficiency of vitamin B12 in primary school students. Consumption of animal products and BMI were identified as statically significant associated factors with serum concentration of vitamin B12.

Uses of nanotechnological feed additives and nanofeeds in poultry feeding

In poultry, which has an important place in meeting the need for healthy animal protein, the production of ration substance compositions with alternative sources is one of the popular topics of the last period. Nanoparticles produced by nanotechnology of various minerals added to poultry diets are increasingly being used as feed additives that can reduce feed costs, reduce the risk of environmental waste, replace antibiotics and do not pose residue risk in animal products, both in terms of supporting growth and development and strengthening the immune system. The aim of this study was to bring together the studies on the effects of using nanoparticles as feed additives on growth, development performance and immune system in poultry

Feeding ecology study of Asian redtail catfish, Hemibagrus nemurus (Teleostei: Bagridae), post-sediment flushing in Jenderal Soedirman Reservoir Central Java, Indonesia

Abstract. Wibowo DN, Sukmaninggrum S, Widyastuti A, Soedibya PHT, Rahayu NL. 2024. Feeding ecology study of Asian redtail catfish, Hemibagrus nemurus (Teleostei: Bagridae), post-sediment flushing in Jenderal Soedirman Reservoir Central Java, Indonesia. Biodiversitas 25: 2315-2322. Hemibagrus nemurus Vallenciennes 1840 is among the valuable fisheries commodities in Banyumas District and led to high exploitation. Research on H. nemurus is essential for its conservation, including its feeding ecology. Feeding ecology studies of H. nemurus have been conducted previously, but the relative examination of this Asian redtail catfish is lacking in Jenderal Soedirman Reservoir, Central Java, Indonesia. Therefore, this study aimed to investigate the feeding ecology of H. nemurus, focusing on post-sediment flushing in the Jenderal Soedirman Reservoir in 2022. Specimens were collected at nine sampling sites in the reservoir during morning and evening sessions, with observed parameters including mouth position, intestine length ratio, intestine content, and the index of preponderance (IP). The results showed that H. nemurus had a subterminal mouth position as well as shorter to slightly longer intestines than the standard body length (SL). Based on the IP value, diets inside the intestine were dominated by animal materials, namely fish compounds. Hence H. nemurus seemed to be predatory considering its detected piscivorous habits. The identified mouth position, intestine length, and dominant diets were similar to the reports on the same species from other regions. These feeding ecology data would provide essential information for the fisheries and conservation of H. nemurus in Jenderal Soedirman Reservoir.

Synthesis Chitosan nanoparticles from Animal Byproducts (Shrimp Shells) Characterization, Physical Properties and Toxicity of Polymeric Nanoparticles in vivo

The study included the extraction of Chitin (Ch) from shrimp shells and preparation of Chitin nanoparticles (NCh) using acid hydrolysis and ultrasound method. In addition, the preparation of chitosan (Chs) and Chitosan nanoparticles (NChs) by Deacetylation method, then we study some of the characteristics, including yield, diameter by Size Analyzer, Field Emission Scanning Electron Microscopy (FESEM), Fourier transform infrared (FTIR) spectroscopy, X-Ray Diffractometer (X-RD), Viscosity, Water Binding Capacity (WBC) and Fat Binding Capacity (FBC). The results showed, (a) decreased the percentage of yield of NChs to 8.20%, (b) the effective diameter of the natural chitosan using a Size Analyzer and was 28121.5 nm, (c) FESEM analysis revealed that the NChs displayed a nanoscale structure with diameters ranged from 20.93 - 30.20 nm (d) the degree of deacetylation (DD%) using FT-IR spectroscopy device, of NChs was (80.21%) compared to Chs 71.45%, and in addition, from the X-ray spectrum, two peaks in spectra of (Ch, NCh) and (Chs, NChs) were observed at the diffraction angles (2θ) which are (10.70-10.99) and (19.99-20.37). Results show increasing the crystallization coefficient of NCh and NChs, while viscosity, WBC and FBC of NChs decreased compared to Chs. The NChs did not show any toxic effect on human blood cells at concentrations of 100-1000 µg. ml-1.

Paleoproteomic identification of the species used in fourteenth century gut-skin garments from the archaeological site of Nuulliit, Greenland

Until recently, the identification of the species of origin for skin and fur materials used in the production of archaeological clothing has been based on the analysis of macro- and microscopic morphological features and on the traditional knowledge of Indigenous groups. This approach, however, is not always applicable due to the deterioration of the archaeological objects. Paleoproteomics was used as an alternative approach to identify the species of origin of fifteen samples of various tissues from approximately 600-year-old garments found in Nuulliit, northern Greenland. Proteomics revealed that a limited group of marine and terrestrial mammals were used for clothing production. The results obtained from the analysis of multiple types of clothing and elements, such as sinew thread and gut skin, suggest that their applications were based on their properties. When conclusive assignment of a sample to a species via proteomics was not possible, the observation by transmitted light microscopy of feather and hair micromorphology, if not affected by diagenesis, was used to improve the identification. The proteomic characterization of animal materials used for clothing production in the Nuulliit archaeological context provides an insight into the practical knowledge and the strategies adopted by the local Indigenous community to exploit natural resources.

Development of collagen brand: development and implementation

New principles for creating technologies for animal products are presented. Despite the large number of domestic developments, protein products or preparations and additives are mainly produced abroad (Great Britain, China, France). In the current situation, it is necessary to maximally support domestic developers and distributors of protein systems that have a very wide range of beneficial properties, which corresponds to modern nutrition concepts and new diets, in particular, J. Axe’s collagen diet.

Skeleton Cluster Tracking for robust multi-view multi-person 3D human pose estimation

The multi-view 3D human pose estimation task relies on 2D human pose estimation for each view; however, severe occlusion, truncation, and human interaction lead to incorrect 2D human pose estimation for some views. The traditional “Matching-Lifting-Tracking” paradigm amplifies the incorrect 2D human pose into an incorrect 3D human pose, which significantly challenges the robustness of multi-view 3D human pose estimation. In this paper, we propose a novel method that tackles the inherent difficulties of the traditional paradigm. This method is rooted in the newly devised “Skeleton Pooling-Clustering-Tracking (SPCT)” paradigm. It initiates a 2D human pose estimation for each perspective. Then a symmetrical dilated network is created for skeleton pool estimation. Upon clustering the skeleton pool, we introduce and implement an innovative tracking method that is explicitly designed for the SPCT paradigm. The tracking method refines and filters the skeleton clusters, thereby enhancing the robustness of the multi-person 3D human pose estimation results. By coupling the skeleton pool with the tracking refinement process, our method obtains high-quality multi-person 3D human pose estimation results despite severe occlusions that produce erroneous 2D and 3D estimates. By employing the proposed SPCT paradigm and a computationally efficient network architecture, our method outperformed existing approaches regarding robustness on the Shelf, 4D Association, and CMU Panoptic datasets, and could be applied in practical scenarios such as markerless motion capture and animation production.

Results from the Danish monitoring programme on pesticide residues from the period 2012–2017 – frequencies and trends in detected pesticides

In order to assess compliance with maximum residue levels in foods and evaluate the exposure of the Danish population to pesticides, a comprehensive monitoring programme was conducted. The work from 2012-2017 involved testing pesticide residues in fruits, vegetables, cereals, animal product and processed commodities. The sampling strategy, mainly based on exposure calculations and previous findings, involved the collection of 13,492 samples primarily from fresh conventional and organic produces on the Danish market. The origin of the samples varied, with 34% being of Danish origin and 67% originating from EU and non-EU countries. The results revealed that residues in conventionally grown produce were detected in 54% of the fruit and vegetable samples, and 30% of the cereal samples. Additionally, residues above the maximum residue limits were found in 1.8% of these samples, most frequently in fruits. As previous years, more residues were found in samples of foreign origin compared to samples of Danish origin. Compared to earlier findings more than 40 pesticides were detected for the first time and including boscalid, imidacloprid, thiacloprid, etofenprox, and spinosad, all detected more than 100 times. The data shows that detection of PFAS pesticides has increased dramatically, from 24 in 2006 to 412 in 2022.

Salmonellosis in Ukraine: An analysis of food products contamination, Salmonella transmission, and serovar diversity during 2012–2023

A laboratory-based surveillance was conducted to study the transmission of Salmonella infection in Ukraine during the period 2012-2023. The study focused on the different categories of food products, feed, and animals as the main transmission factors and tried to analyze the relationship between them. The serological profile of Salmonella was predominantly observed in samples from objects of veterinary control, including biological/pathological material from animals and biomaterials from poultry within the National Poultry Salmonellosis Control Program. The study found that the most frequently isolated serovars were S. Enteritidis (20.03%), followed by S. Typhimurium (14.76%), S. Pullorum (without biovar identification;10.71%), S. Pullorum biovar Pullorum (10.50%), S. Pullorum var. Gallinarum (6.62%), S. Choleraesuis (5.79%), S. Livingstone (2.53%), and S. Infantis (1.70%). In 2021, an isolate of monophasic S. Typhimurium was identified for the first time in pathological material from pigs. The study also found that the most frequent Salmonella-positive categories of food products in Ukraine were meat and meat products (78.16%), eggs and egg products (11.75%); dairy products (3.319%), fish products (2.71%), ready-to-eat food products (1.96%). The largest specific share of Salmonella isolates from food products and feed was S. Enteritidis, followed by serotypes such as S. Infantis, S. Typhimurium, S. Livingstone, S. Virchow, and rare serotypes such as S. Nigeria and S. Thompson. The dominance of certain serovars such as S. Enteritidis, S. Typhimurium, S. Infantis, S. Livingstone, and S. Virchow in biomaterials from sick animals indicates their primary role in the infection of food products of animal origin. Hence, a stress to enhance diagnostic and monitoring frameworks at animal herd levels. The findings of this study can be used as a basis for evidence-based epidemiology, as well as for the implementation of joint steps to improve the effectiveness of control measures against salmonellosis in each region.

MILK QUALITY OF ETAWA BREEDING GOATS SEEN FROM CALIFORNIA MASTITIS TEST, ALCOHOL TEST, REDUCTASE TEST, AND BOILING TEST IN RAKA ETAWA FARMING

Milk is a food product of animal origin that has high benefits. The main requirement for milk consumption by the public is good milk quality. This study aims to determine the quality of Etawa breeding goat milk as seen from the California mastitis test, alcohol test, reductase test, and boiling test at Raka Etawa Farm and see the relationship between the California mastitis test (CMT) with the alcohol test, reductase, and boiling test. This study was conducted in a descriptive observational. Sampling using purposive sampling method with sample criteria taken is milk from goat mothers who are in the lactation period. In this study it was found that of the 30 milk samples taken, based on the results of the California mastitis test, there were 15 samples of milk of Etawa breeding goats (50%) experiencing the incidence of subclinical mastitis level III, 11 milk samples (36,7%) experiencing the incidence of subclinical mastitis level II, and as many as 4 milk samples (13,3%) did not experience the incidence of subclinical mastitis. Based on the alcohol test, 26 milk samples (80%) showed positive results and as many as 4 milk samples (20%) showed negative results. The reductase test results showed that 24 samples (80%) had a reductase time of 2 hours and 6 samples (20%) showed a reductase time of 1 hour. The boiling test results showed that 26 milk samples (86,7%) were positive and 4 milk samples (13,3%) had negative results. There was no significant relationship between the CMT test and alcohol test and the CMT test and reductase test (P > 0.05). There was a significant relationship between the CMT test and boiling test (P < 0.05) on the quality of milk of Etawa breeding goats at Raka Etawa Farm. It can be concluded that the majority of Etawa breeding goat milk at Raka Etawa Farm is of poor quality. Cage hygiene, cleaning the udder before milking, and always using gloves during milking need to be considered to produce good quality milk by applicable standards.

ESCHERICHIA COLI CONTAMINATION ON IMPORTED FROZEN Buffalo MEAT SOLD AT AIKMEL TRADITIONAL MARKET, AIKMEL DISTRICT, EAST LOMBOK DISTRICT, WEST NUSA TENGGARA PROVINCE

The demand for beef in Indonesia continues to increase. The government is striving to achieve self-sufficiency in beef production, but the high price of beef is driving imports of buffalo meat from India. Buffalo meat has high nutritional value, similar to beef. Since 2015, frozen buffalo meat imports from India have begun to enter Indonesia, particularly in West Nusa Tenggara, as an effort to meet market demand in the modern shopping areas in Mataram City, Lombok. The relatively cheap price of frozen buffalo meat has led to expanded marketing in East Lombok, especially in the traditional market of Aikmel, which is approximately 72 km away from Mataram. The aim of this research is to determine the extent of Escherichia coli contamination and the amount of Escherichia coli contamination per gram of buffalo meat sold in this traditional market. The research samples consist of frozen buffalo meat from India sourced from 10 Indian buffalo meat vendors in the Aikmel market, each weighing 100 grams. The isolation and identification method follows Jawetz et al. (2008), starting with isolation on Eosin Methylene Blue Agar (EMBA), followed by identification with INMVIC (Indole, Methyl Red, Voges Proskauer, Citrate), reinforced by results from TSIA (Triple Sugar Iron Agar) and Urease tests. The research found that E. coli contamination exceeded the specified limit (SNI 7388:2009, 2009) in 9 out of 10 samples taken from 10 Indian buffalo meat vendors in the Aikmel market. The smallest and largest amounts of E. coli contamination in 90% of the contaminated samples were 80x101 and 7x103 colonies/gram, respectively. This condition is crucial for the government to pay attention to, in order to enhance education and supervision of the public regarding the procedures and regulations for the sale of frozen buffalo meat from India, in accordance with the marketing of animal origin products.

Kyrgyz Youth from Past to Present: Opportunities and Threats

Kyrgyz is a deep-rooted nation history of which goes back to ancient times. Before passing to the settled life, Kyrgyz people lived in a nomadic life. As a necessity of nomadic life, they earned their lives by farming and they met their needs thorough animal breeding. As a house, they lived in “boz uy” that is a traditional Kyrgyz house made of felt. While they lived in their traditional house, they taught their children to make various clothes from animal materials and used animal milk and wool. This traditional life style was transferred from the old generation to the young generation through the history. More importantly religious and moral teaching took place in this traditional house, “boz uy.” Parents not only taught their children the traditional life style, but also taught them human relations such as regard for old people, love for children, hospitality and others.

Challenges and Opportunities of Virtual Reality Painting Animation in Mainland China: A Case Study of Dark Tide

This article draws on the experience of producing the music video Dark Tide in Quill, a virtual reality painting software, to discuss the potential of integrating virtual reality (VR) technology into the animation industry workflow. Despite significant updates in VR content-creation technologies over the past seven years, many animation companies in Mainland China are reluctant to include these innovative technologies in their animation production workflows due to a lack of knowledge and drawbacks in the VR workflow. However, in light of uncertainty within the animation market and the commercial success of independent animation, VR painting technology could provide start-up animation studios with an alternative animation production workflow and production strategies for their future projects. Against this background, we examine the current advantages and limitations of Quill.

Preface

Welcome to the proceedings of the The 10th International Seminar on Tropical Animal Production (ISTAP X) organized by Faculty of Animal Science, Universitas Gadjah Mada. In the midst of escalating concerns about the environmental impacts of animal production and the imperative to ensure global food security, this symposium serves as a crucial platform for scholars, researchers, policymakers, and industry professionals to converge and deliberate on pressing issues. The title of our symposium, “Sustainable Animal Productivity and Environmental Footprint Toward Global Halal and Food Security,” encapsulates the multifaceted challenges we face today. As the world’s population burgeons and economies expand, the demand for animal products escalates, placing immense pressure on our environment and resources. Yet, this surge in production comes at a cost—degradation of ecosystems, deforestation, habitat loss, and a myriad of environmental woes. Concurrently, the burgeoning demand for halal food, driven by the expanding Muslim population, necessitates innovative approaches to ensure the sustainability and integrity of supply chains. The backdrop against which this symposium unfolds is one characterized by urgency and complexity. Traditional agricultural practices, marked by inefficiencies and resource-intensive methods, are no longer tenable in the face of escalating global challenges. The need of the hour is a paradigm shift towards sustainable animal production systems that reconcile productivity with environmental stewardship. Throughout this symposium, esteemed experts from diverse disciplines will engage in rigorous discourse, sharing insights, methodologies, and innovative solutions aimed at fostering sustainable animal productivity while mitigating environmental footprints. By fostering interdisciplinary collaboration and knowledge exchange, we aspire to chart a path towards a more sustainable, resilient, and equitable future for animal production systems worldwide. The contributions contained within these proceedings represent the culmination of rigorous research, thought-provoking insights, and practical applications. We extend our deepest gratitude to all the authors, presenters, attendees, and organizers whose collective efforts have made this symposium a resounding success. As we embark on this intellectual journey, let us remain steadfast in our commitment to forge a harmonious balance between the imperatives of productivity, environmental sustainability, halal integrity, and global food security.

ФІНАНСОВИЙ АНАЛІЗ ІННОВАЦІЙНО ОРІЄНТОВАНИХ ПІДПРИЄМСТВ АГРОПРОДОВОЛЬЧИХ СОЦІАЛЬНО-ЕКОНОМІЧНИХ СИСТЕМ В УМОВАХ РИНКОВОГО ЦІНОУТВОРЕННЯ

The following trends characterize the economic development of innovatively oriented enterprises of agri-food socio-economic systems in the conditions of market pricing: there is an increase in the overall production of food products, beverages and tobacco products, in particular pork,poultry and canned goods from them, vegetables, sunflower oil, liquid milk, cereals, non-carbonated mineral water, cigarettes; growth per person. In Ukraine, the production of the following food products and beverages increased: pork and poultry meat, canned vegetables, sunflower oil, liquid milk, butter, and non-carbonated mineral water. At the same time, there was a reduction in the production of sausage products, certain fruit products, margarine, cheese, certain dairy products, flour, bread, flour products, chocolate, confectionery, and beverages. There is a decrease per capita in the production of such food products and beverages in Ukraine as sausages, juices, some other fruit products, margarine, cheese, certain dairy products, bread and bakery products, chocolate, sugar confectionery, carbonated mineral water, beverages non-alcoholic; growth of wholesale turnover of food products and the share of sales of domestic food products with a simultaneous reduction in the specific weight of food in the structure of wholesale turnover. There was a decrease in the volume of retail sales of certain food product groups, in particular, such as: meat and meat products, butter, vegetable oils, cheese, eggs, confectionery, tea, flour, bakery and pasta products, potatoes, vegetables, fruits , berries, grapes; positive dynamics of retail turnover of food products, which is obviously related to the dynamics of solvent demand of the population. We also observe an increase in the specific share of products of vegetable and animal origin, live animals, fats and oil in the structure of the state's exports, while the share of ready-made food products decreases. In general, the volume of food exports increased; the specific weight of ready-made food products, products of plant origin, fats and oils in the structure of national imports increased, while the share of live animals and products of animal origin decreased at the same time

Alpha-Gal syndrome as a novel food allergy: a case report study

Introduction and importance: Alpha-Gal syndrome (AGS), a distinct form of mammalian meat allergy, presents unique characteristics that set it apart from typical IgE-mediated food hypersensitivities. AGS induces an allergic response typically 3–6 h post-ingestion of mammalian meat, such as beef, pork, or lamb. This prolonged reaction time differentiates AGS from other food allergies, which usually provoke a more immediate response. Case presentation: The authors present a case of a 35-year-old male patient who, unbeknownst to him, had been experiencing symptoms consistent with Alpha-Gal allergy for several years. His symptoms only subsided upon the complete elimination of mammalian meat from his diet. It was only then that the possibility of AGS was considered. Complete abstinence from mammalian meat, meat by-products, and other α-Gal containing foods is the most effective preventative strategy for AGS. No definitive cure for AGS has been established as of now. Treatment protocols for hypersensitivity reactions are contingent upon the severity of the reaction, with therapies ranging from antihistamine medications to the administration of epinephrine. Conclusion: There is considerable variability among AGS patients concerning the consumption of dairy products. Some individuals with AGS can safely consume dairy products without any adverse reactions, while others are advised to abstain due to potential allergenic responses. This variability in dairy tolerance among AGS patients warrants further investigation.

Recent advances on applying for liquid nitrogen quick-freezing in aquatic animal products

Recent advances on applying for liquid nitrogen quick-freezing in aquatic animal products

Validation and application of a method for determination of multi-class pesticides in muscle chicken breast fillets using QuEChERS extraction and GC/MS.

The occurrence of pesticide residues in animal products deserves attention because of the contamination by environmental pollutants and pesticides that may be present in the food that animals are fed. The goal of this work was the validation of a method for detection of residues of multiple classes of pesticide and determination of their residues in chicken breast fillets. Gas chromatography with mass spectrometry was used for analysis. A modified quick, easy, cheap, effective, rugged and safe (QuEChERS) method was put into practice for its validation and applied to real samples. The study optimised mass detection and investigated the effect of a freezing step during the preparation of samples. Pesticides were determined in samples from conventional and organic production. The impact of the matrix effect decreased, with the largest number of pesticides and satisfactory recovery determined by the application of mixed solvent acetonitrile and ethyl acetate for extraction. Detection of pesticide residues was achieved in a linear range between 5 and 50 µg/kg with satisfactory excellent correlation coefficients greater than 0.99. The recovery of all the pesticide residues ranged between 71.2 and 118.80%. The relative standard deviation was from 2.9% to 18.1% for all validated pesticide residues. The limits of quantification were in the range of 3.0-4.9 µg/kg. Out of 56 pesticide residues analysed in real samples, 5 were detected: α endosulfan, cypermethrin, endosulfan sulphate, permethrin and p,p´-dichlorodiphenyltrichloroethane (DDT) and their concentrations ranged from 4.9 to 15.2 µg/kg. All tested samples were compliant with the evaluation criteria, and detected values of pesticide residues were lower than the maximum residual levels.
