Additional Value

Insects or products derived from insects are considered as a valuable feed ingredient for aquaculture, poultry, and pigs but also exert possible secondary effects of health stimulators in livestock as reported in literature. Health benefits attributed to insects can create additional value in the insect chain. Three categories of bioactive compounds in insects are reported in this desk study: antimicrobial peptides (such as α-helical peptides, cysteine-rich peptides, proline-rich peptides, glycine-rich peptides), fatty acids (especially lauric acid), and polysaccharides (especially chitin and chitosan). The review summarises the recent literature on these three categories. Antimicrobial properties or immuno-modulating effects may contribute to reduce the use of antibiotics and to avoid antibiotic resistance in livestock when these insect products are included in animal diets. Furthermore, antioxidant capacity of insect-proteins might reduce collateral tissue damage. Health stimulating effects of insect products may result in additional applications of insect products in animal feed for livestock.

Nutraceutical Properties

Papaya seeds, though rarely eaten, are used in folk medicine around the world. This study analysed the seeds to evaluate their nutritional and phytochemical content using standard methods. Proximate analysis showed the seeds are a good source of carbohydrate (48.91% ± 0.69) and protein (24.33% ± 0.74). Essential minerals such as iron (70.16 mg/kg ± 0.08), selenium (12.50 mg/kg ± 0.08), and calcium (26.96 mg/kg ± 0.08) are present in the seeds at optimal quantities. Amino acid and vitamin analysis indicated that papaya seeds are rich sources of vitamin A (117.28 ± 2.09 mg/kg), B6 (37.70 ± 1.84 mg/kg), D (27.60 ± 3.96 mg/kg), K (119.81 ± 15.88 mg/kg), and all essential amino acids. Phytochemical analysis of the seeds revealed forty-three bioactive compounds including acetic acid and pyrrole, both of which have antimicrobial properties. From the above analytical results, it was revealed that papaya seeds have nutraceutical properties and can be used, in the appropriate quantity as a food or health supplement or an adjunct animal feed.

Measurement Results

The article raises the problem of ensuring metrological traceability of the measurement results of indicators of quality and nutritional value for food products and food raw materials: water (moisture), nitrogen (protein, crude protein), fat, ash and carbohydrates. The problem under consideration can be solved by applying reference materials of food composition, traceable to state primary measurement standards GET 173-2017 and GET 176-2019 and primary reference measurement procedures (PRMP), for attestation of measurement procedures and accuracy checking of measurement results. The article discusses the results of the PRMP development of mass fraction of fat, ash and carbohydrates in food products and food raw materials, as well as mass fraction of crude fat (oil content) in oil crops seeds and products based on them. The paper also presents metrological characteristics of reference materials of composition of dry dairy products, grain-milk dry porridges for nutrition of babies, grain dry porridges for nutrition of babies, egg powder, freeze-dried meat products, animal feed. The results of the work allow for building a chain of metrological traceability from GET 173-2017, GET 176-2019 and PRMP to routine measurement procedures, thereby ensuring the uniformity of measurements of nutritional value of food products.

Farm Inputs

Russian policy makers argue that agriculture suffers from decapitalization due to financial constraints faced by producers. This view is the basis for the national agricultural policy, which emphasizes reimbursement of input costs and substitutes government and quasi-government organizations for missing market institutions. The article evaluates the availability of purchased farm inputs, the efficiency of their use, the main problems in the emergence of market institutions, and the impact of government policies. The analysis focuses on five groups of purchased inputs: farm machinery, fertilizers, fuel, seeds, and animal feed. The information sources include official statistics and data from two original surveys.

Animal feed knife is a tool that serves to cut and chop animal feed consisting of grass as the main ingredient with additives such as bran, herbs, centrate, cassava, tofu pulp and others. Therefore, as a cutting tool must have the properties of friction resistance, impact resistance, and have good sharpness, so that the material chosen is Ni-Hard 1. The use of centrifugal casting method was chosen because it has the advantage of being able to make castings with relatively thin thickness this is due to the influence of the centrifugal force on the distribution of metal liquids throughout the cavity in the mold. Case study in this study is the use of centrifugal casting methods as an alternative to gravity casting methods to overcome defects of misruns. This research was conducted to investigate the effect of speed on the formation of castings products. The method that was carried out began with a literature study on centrifugal casting, and continued by determining the material, the temperature of the cast is in the range 1250ºC - 1300ºC, and the type of mold. The next step is to do work drawings, pattern making, mold making, casting processes, fettling processes, and analysis. With variations in speed of 200 rpm, 300 rpm and 400 rpm, it can be seen the optimal speed for making this product. The results of this study obtained optimal speed at a speed of 300 rpm to make good quality of animal feed knife products.

Introduction. The article deals with the main traditional outbuildings of the Mordvinians, reported on their functional purpose in economic activity. The forms and types of outbuildings, as well as the main building materials used by Mordvinians are described in details. Their significance in the religious and ceremonial life of the ethnic group is shown. Materials and Methods. The research is based on traditional methods of ethnographic science, such as field observation, survey and interviews, and a comprehensive approach. Among the methods of historical science comparative-historical, historical-genetic, problem-chronological, structural-system were used. Among the general scientific methods of research logical, descriptive, narrative, generalization, classification and systematization were involved. To achieve the results of the study, the materials collected by the authors in the course of field surveys conducted in the Mordovian villages were mainly used. Results and Discussion. Traditional outbuildings were of great importance in the economic activity of the Mordovian ethnic group. According to their functional purpose, they can be divided into the following groups: for livestock and poultry (stable, chicken coop, stable, kalda), sanitary and hygienic (bath), warehouse buildings for storage of food, utensils, firewood, animal feed (barn, cellar, woodshed, hayloft), for processing of grain (sheep, riga, mill). Depending on the welfare and financial capacity of the family, the number of outbuildings was different. As a rule, the wealthier families had more outbuildings than the less wealthier ones. The main building material for the construction of these buildings was wood. Conclusion. Thus, the traditional outbuildings of the Mordvinians occupied an important place in its economic activities. At the same time, each of them had its own purpose and performed certain functions. Some buildings, such as a bath and a barn, had not only economic purpose, but also were the venue for a number of prayers and ceremonies. It is now ordinarily they have banya (bath-house), outdoor courtyard with standing in different places sheds, barn and cellar.

This book examines the politics of consumer and environmental risk regulation in the United States and Europe over the last five decades, explaining why America and Europe have often regulated a wide range of similar risks differently. It finds that between 1960 and 1990, American health, safety, and environmental regulations were more stringent, risk averse, comprehensive, and innovative than those adopted in Europe. But since around 1990 global regulatory leadership has shifted to Europe. What explains this striking reversal? This book takes an in-depth, comparative look at European and American policies toward a range of consumer and environmental risks, including vehicle air pollution, ozone depletion, climate change, beef and milk hormones, genetically modified agriculture, antibiotics in animal feed, pesticides, cosmetic safety, and hazardous substances in electronic products. The book traces how concerns over such risks—and pressure on political leaders to do something about them—have risen among the European public but declined among Americans. The book explores how policymakers in Europe have grown supportive of more stringent regulations while those in the United States have become sharply polarized along partisan lines. And as European policymakers have grown more willing to regulate risks on precautionary grounds, increasingly skeptical American policymakers have called for higher levels of scientific certainty before imposing additional regulatory controls on business.
