The determining factor in increasing the productivity of farm animals is the provision of comlete feeding of animals through feed additives. Among the functional feed additives containing essential trace elements, a special place under the conditions of the Amur region is given to microadditives of selenium, iodine and cobalt. The Amur region belongs to the biogeochemical region in which the defi ciency of I, Se and Co in feed is from 80 to 95 % compared to the average Russian indicators. The purpose of the work was to compare the eff ect of feed additives made from red alga Ahnfeltia, soy protein asparaginates separately and together with the drug “Creamino” on the growth, development and metabolism of young cattle. Under the conditions of the Amur region on the basis of their own experimental data in the rearing of young cattle, the eff ectiveness of the use of the drug “Creamino” and red alga Ahnfeltia has been scientifi cally justifi ed. The conducted scientifi c and economic and physiological experiments allowed us to determine the eff ect of red anfel on the growth and development, metabolic processes of replacement heifers and the growth rate of steers when they were fed soy protein asparaginates together with the drug “Creamino”. The evaluation of the economic effi ciency of feeding heifers I, Co and Se in organic form as part of soy protein asparaginates and red alga Ahnfeltia has shown a higher economic eff ect per 1 head per day in the 2nd experimental group, where the level of profi tability was 28,6 %. The results of the research and production experiment on steers have shown that from an economic point of view, it is advisable to use I, Co and Se in their rations in the form of soy protein asparaginates together with the drug “Creamino”, feeding of which can signifi cantly increase the economic eff ect, which is 1 head per day of 4,47 rubles with a profi tability level of 31,0 %.

The progress in animal improvement depends on the accuracy with which the breeding value of each individual in the breed, or herd, is estimated, and how the animals chosen on the basis of our estimates are combined in matings. We are concerned here only with the first part of the problem, i.e. the estimation of breeding values. The estimates are made in regard to certain characters, or traits, which are of particular interest from an economic point of view, and they may be based on the phenotypic merit of the individual, or on the merits of its ancestors or collateral relatives, or on the merits of its progeny, in regard to the character in question. Often a combination of two, or three, or all four methods may be used. Their relative importance depends on the heritability of the character, as will be discussed later.

Scientific researches have been proved that a more complete disclosure of the productive potential of farm animals is possible when they use a full range of different feed, vitamins, premixes and different feed additives. Currently, all these components are given to animals in the form of a compound feed, the preparation of which is carried out in crumbled or pelletized form. Preference is given to pelletized feed, because it has great advantages over crumbled feed. It has been noted that when feeding young cattle with pelletized feed the average daily of live weight has increased by 6,1 % than when feeding with crumbled feed. When feeding piglets with pelletized feed the increase was 8,2 % more. Feeding fur-bearing animals with dry pelletized feed can increase economic efficiency by reducing the cost of the diet by 1,44 times. The results of testing the equipment of LLC “Doza-Agro” for the production of pelletized feed in terms of its quality have been presented in the article. Evaluationof the workflow of the equipment has been carried out as part of the compound feed plant series “Profi ” located in the village Sultan-Saly in the Rostov region. The description of the compound feed plant and its elements has been given, the methods according to which the research was carried out have been described, and the laboratory equipment for determining the quality indicators of the feed has been presented. The quality of macronutrients grinding feed crusher DZM-6, the quality of mixing feed elements in the mixer SLG-2A and the quality of feed pellets obtained in the granulator DG-10Nhas been evaluated. Comparison of the obtained data with the values prescribed in the GOSTs has been shown compliance of the prepared granules with the requirements of standards.

A common component of all breeding programs for working with breeds, populations, and herds is to increase the genetic potential, preserve and improve the gene pool of valuable domestic breeds of farm animals, including dairy cattle. Methods of molecular genetics allow us to study, evaluate, and predict breeding, productive traits that persistently transmit and progressively develop in generations. The purpose of these researches was to study the polymorphism of genes: Kappacasein – CSN3, pituitary transcription factor – PIT-1, prolactin – PRL, somatotropin – GH and searching the association of their polymorphic variants with the indicators of dairy productivity of Yaroslavlskaya breed of cows bred in the Stavropol Territory. It has been found by using PCR-PDRF methods that the polymorphism of the studied genes is represented by two alleles: gene CSN3 – alleles CSN3A and CSN3B ; gene PIT-1 – PIT-1A and PIT-1B ; gene PRL – PRLA and PRLB , gene GH – GHL and GHV , and three genotypes – CSN3AA, CSN3BB, CSN3AB; PIT-1AA, PIT-1BB, PIT-1AB; PRLAA, PRLBB, PRLAB; GHLL, GHVV, GHVL, respectively. The frequency of occurrence of selectively signifi cant alleles has been determined, and genotypes of carriers of genetic markers have been identifi ed. It has been found that the specifi c weight of animals carrying genocomplexes of 4 genes and 8 desirable alleles was 0,63, of 4 genes and 7 marker alleles – 3,16, of 4 genes and 6, 5, 4 marker alleles – 20,87 %. Most of the animals (62,7 %) were carriers of genocomplexes of 4, 3, 2 genes and 2 marker alleles. The conclusion has been made about necessity of wide use of genotypes the carriers of genetic markers in the selection process that will ensure gathering in herds of Yaroslavskaya breed of desirable alleles and create conditions for improving the effi ciency of its breeding in the Stavropol Territory.

To implement any successful policy, research about the subject-matter is essential. Lack of knowledge would result in failure and, from an economic point of view, it would lead to a waste of scarce resources. The book under review is essentially a manual which highlights the use of research for development. The book is divided into two parts. Part One informs the reader about concepts and some theory, and Part Two deals with the issue of undertaking research for development. Both parts have 11 chapters each. Chapter 1 asks the basic question: Is research important in development work? The answer is that it is. Research has many dimensions: from the basic asking of questions to the more sophisticated broad-based analysis of policy issues. The chapter, in short, stresses the usefulness of research which development workers ignore at their own peril.

ABSTRACT This case originates from a real-life business situation and illustrates the application of impairment tests in accordance with IFRS and U.S. GAAP. In the first part of the case study, students examine conceptual questions of impairment tests under IFRS and U.S. GAAP with respect to applicable accounting standards, definitions, value concepts, and frequency of application. In addition, the case encourages students to discuss the impairment regime from an economic point of view. The second part of the instructional resource continues to provide instructors with the flexibility of applying U.S. GAAP and/or IFRS when students are asked to test a long-lived asset for impairment and, if necessary, allocate any potential impairment. This latter part demonstrates that impairment tests require professional judgment that students are to exercise in the case.

Dissemination And Implementation Research

This chapter presents an overview of how D&I research can be evaluated from an economic point of view. Dissemination and implementation imposes costs upon knowledge purveyors, provider organizations, public health organizations, and payers (including governments). However, whether these added costs will result in improved service delivery and, perhaps more importantly, client outcomes and improvements in population health remain as open questions. If emerging studies reveal that defined implementation strategies are more cost effective than “usual” implementation, then policymakers and service providers will need to resource these added costs of implementation in order to assure the success and sustainability of high-quality health services over the long term.

High Sugar Content

To make biofuel production feasible from an economic point of view, several studies have investigated the main associated bottlenecks of the whole production process through approaches such as the “cradle to grave” approach or the Life Cycle Assessment (LCA) analysis, being the main constrains the feedstock collection and transport. Whilst several feedstocks are interesting because of their high sugar content, very few of them are available all year around and moreover do not require high transportation’ costs. This work aims to investigate if the “zero miles” concept could bring advantages to biofuel production by decreasing all the associated transport costs on a locally established production platform. In particular, a specific case study applied to the Technical University of Denmark (DTU) campus is used as example to investigate the advantages and feasibility of using the spent coffee grounds generated at the main cafeteria for the production of bioethanol on site, which can be subsequently used to (partially) cover the campus’ energy demands.

The energy sector in Chile demands a significant increase in renewable energy sources in the near future, and concentrated solar power (CSP) technologies are becoming increasingly competitive as compared to natural gas plants. Motivated by this, this paper presents a comparison between solar technologies such as hybrid plants and natural gas-based thermal technologies, as both technologies share several characteristics that are comparable and beneficial for the power grid. This comparison is made from an economic point of view using the Levelized Cost of Energy (LCOE) metric and in terms of the systemic benefits related to flexibility, which is very much required due to the current decarbonization scenario of Chile’s energy matrix. The results show that the LCOE of the four hybrid plant models studied is lower than the LCOE of the gas plant. A solar hybrid plant configuration composed of a photovoltaic and solar tower plant (STP) with 13 h of storage and without generation restrictions has an LCOE 53 USD/MWh, while the natural gas technology evaluated with an 85% plant factor and a variable fuel cost of 2.0 USD/MMBtu has an LCOE of 86 USD/MWh. Thus, solar hybrid plants under a particular set of conditions are shown to be more cost-effective than their closest competitor for the Chilean grid while still providing significant dispatchability and flexibility.
