Aim. To investigate the genetic structure of New Zealand white rabbits population by different types of DNA- markers. Methods. The individual genotypes of animals were identifi ed using the polymerase chain reaction with further determination of the restriction fragment length polymorphism (RFLP-analysis). Results. The data on the distribution of allele variants of molecular markers in the population of rabbits were obtained; the impact of the genotype factor on meat production, prolifi cacy and milk production traits was determined. The relationship between genotypes by polymorphic DNA-markers of myostatin and progesterone receptor of animals and the values of meat productivity traits and reproduction capability was established. It was demonstrated that TT homozygotes excel other animals in the indices of average daily growth, while GG homozygotes excel others in prolifi cacy. Conclusions. The “desired” genotypes by myostatin gene (CC) and myostatin of rabbits were revealed. They may be used for targeted selection with the purpose of increasing the indices of meat production.

The Impact

Scottish Blackface sheep have a multi-purpose role in the UK to produce breeding females and lambs for meat consumption. Over the last fifty years, wool has accounted for a very low proportion of economical return from hill sheep production in the UK. In recent years, the ratio of the value of lamb meat to wool clip has altered, with wool becoming relatively more important in particular for hill breeds. The consequence of direct selection for improved carcass traits in these breeds on wool quality is unknown. With other sheep breeds such as Merino, selection for improved wool traits has largely been undertaken with little regard to the impact on meat production. The objectives of this study are to quantify wool quality traits and examine genetic relationships between wool quality and carcass traits in Scottish Blackface sheep.

The Impact

The Thau lagoon (France) has been studied for many years because of its ecological interest related to economic activities: shellfish cultivation, tourism, and industry. The standing stock of cultivated filter feeders is around 20 000 t and consists of two main species, the Japanese oyster Crassostrea gigas and the Mediterranean mussel Mytilus galloprovincialis. To predict changes in the standing stock and the annual production, a mathematical model of the population dynamics was defined. It was based on the continuous equation of the density as a function of the mortality rate, the individual growth rate, and the interindividual variability. The daily growth rate was derived from field surveys and depended on the phytoplankton concentration and individual weight. The model also took into account the rearing strategy of the producers defined by the timetable of seeding and harvesting, obtained by an inquiry among the producers and used to simulate real cases of standing stock changes. The model was also used to assess the potential impact on the environment through the computation of the food consumption, which was compared with the residence time and the primary production.

   Phospholipids are a kind of “solvents” of cholesterol and show a hepatoprotective effect. Also, phospholipids regulate fat and carbohydrate metabolism, improve the functional activity of the liver and its detoxification function. The study aims to study the impact of different doses of phos-pholipid lecithin preparation on economically useful indicators, meat productivity, nutritional value and environmental safety of quail meat at a subtoxic dose of nitrates in their compound feed. This article presents materials that indicate the feasibility of introducing phospholipid preparation of lecithin in the amount of 1.0 % by weight of feed under the presence of a sub-toxic dose of nitrates in the compound feed quail grown for meat. This introduction of phospholipid preparation of lecithin increases the preservation of livestock, body weight gain and reduces the cost of feed per unit gain. Poultry of the 2nd experimental group had an advantage over their control counterparts in preservation rate by 4.0 % and average daily growth by 9.50 % (P<0.05). The authors observed the benefit over the control samples in the concentration of dry substances by 0.98 and 0.99 %, protein by 0.98 and 0.97 % (P<0.05) in the examples of thigh and breast muscles of the poultry of the 2nd experimental group. The value of the protein-quality index (PQI) was higher by 13,55 % (P<0,05) in the samples of white meat from poultry carcasses of the 2nd experimental group as compared with the control counterparts. Also, the examples of poultry meat of the 2nd experimental group had better sanitary and hygienic characteristics. For instance, they had 36.83 % lower nitrate content (P<0.05) and 40.91 % lower nitrites content (P<0.05). This content indicates high denitrifying properties of phospholipid lecithin.

In modern poultry farming, along with classical breeding methods based on phenotype analysis, it is possible to use MAS breeding, which includes genotype assessment. Meat productivity is influenced by live weight and body characteristics of the bird. This article analyzes the influence of the rs316247861 marker of the myostatin gene on the conformation parameters of Pushkin breed chickens. For the analysis, 140 heads of Pushkin breed chickens were taken. Exterior assessment was carried out in chickens at the age of 330 days according to 17 indicators: body weight, body length, body + neck length, oblique body length, thigh length, chest depth, chest width at collarbones, pelvic width, chest girth, metatarsal girth, shin girth , chest angle (degree), keel length, metatarsal length, tibia length, oblique body length with a tape (KDT), tibia length with a tape. PCR-RFLP analysis was performed using the restriction endonuclease BstHHI enzyme. As a result of the study of the experimental population of Pushkin breed chickens, carriers of the CC genotype were significantly superior to individuals with the GG genotype in terms of indicators affecting the formation of poultry meat productivity. In the sample of chickens of the studied population, the value χ2=10.29, which allows us to conclude that the genetic equilibrium is shifted, this is a sign of strong selection pressure. Thus, in the experimental population of the Pushkin breed, the CC genotype is desirable for selection for poultry meat productivity. In this regard, the MSTN gene and its expression product deserve special attention, among the issues of both molecular genetics and animal husbandry.

The article presents the outcomes of studies confirming the feasibility of using zeolite-containing additives with the objective to optimize the diet of young cattle and horses by the content of minerals in it in order to increase their meat productivity. The research has been conducted in the Republic of Tatarstan. Laboratory studies have confirmed that in terms of hazard the zeolite-containing feed additive belongs to the fourth class of chemicals, specifically, low-toxic compounds in accordance with the requirements of State Standard 12.1.007.76. Scientific and economic experiments have established that the use of a zeolite-containing additive in the diets of young cattle and horses during a store period contributed to an increase in their average daily growth by 10.8 and 12.0 % and slaughter weight by 7.4 and 6.3 % (p<0.05). The slaughter yield in animals of the experimental groups was 54.0 and 58.9 %. The profitability of beef and horse meat production was 17.4 and 19.3 % respectively.

This article has two purposes: (a) to examine the relationship between intercultural power relations and the widespread practice of accent discrimination and (b) to underscore the ramifications of accent discrimination both for the individual and for global society as a whole. First, authors review social theory regarding language and group identity construction, and then go on to integrate more current studies linking accent bias to sociocultural variables. Authors discuss three examples of intercultural accent discrimination in order to illustrate how this link manifests itself in the broader context of international relations (i.e., how accent discrimination is generated in situations of unequal power) and, using a review of current research, assess the consequences of accent discrimination for the individual. Finally, the article highlights the impact that linguistic discrimination is having on linguistic diversity globally, partially using data from the United Nations Educational, Scientific and Cultural Organization (UNESCO) and partially by offering a potential context for interpreting the emergence of practices that seek to reduce or modify speaker accents.

Abstract. Background: Self-esteem is a major contributor to risk for repeated suicide attempts. Prior research has shown that awareness of stigma is associated with reduced self-esteem among people with mental illness. No prior studies have examined the association between self-esteem and stereotype awareness among individuals with past suicide attempts. Aims: To understand the relationship between stereotype awareness and self-esteem among young adults who have and have not attempted suicide. Method: Computerized surveys were administered to college students (N = 637). Linear regression analyses were used to test associations between self-esteem and stereotype awareness, attempt history, and their interaction. Results: There was a significant stereotype awareness by attempt interaction (β = –.74, p = .006) in the regression analysis. The interaction was explained by a stronger negative association between stereotype awareness and self-esteem among individuals with past suicide attempts (β = –.50, p = .013) compared with those without attempts (β = –.09, p = .037). Conclusion: Stigma is associated with lower self-esteem within this high-functioning sample of young adults with histories of suicide attempts. Alleviating the impact of stigma at the individual (clinical) or community (public health) levels may improve self-esteem among this high-risk population, which could potentially influence subsequent suicide risk.

Levels Of Support

Existing research has consistently shown that perceptions of the potential economic consequences of Scottish independence are vital to levels of support for constitutional change. This paper attempts to investigate the mechanism by which expectations of the economic consequences of independence are formed. A hypothesised causal micro-level mechanism is tested that relates constitutional preferences to the existing skill investments of the individual. Evidence is presented that larger skill investments are associated with a greater likelihood of perceiving economic threats from independence. Additionally, greater perceived threat results in lower support for independence. The impact of uncertainty on both positive and negative economic expectations is also examined. While uncertainty has little effect on negative expectations, it significantly reduces the likelihood of those with positive expectations supporting independence. Overall, it appears that a general economy-wide threat is most significant, and it is conjectured that this stems a lack of information on macroeconomic governance credentials.

The Impact

This article presents the results of studying the impact of housing and feeding conditions on broiler chickens of Hubbard RedBro cross, as well as the quality of products obtained when using floor and cage content, in a farm. It established that when receiving a mixed feed of own production using feed raw materials grown on a farm without the use of pesticides, a statistically significant decrease in potentially dangerous substances for animal health is recorded. Compared with factory feed, it has reduced the content of pesticides by 14 times, and mercury and arsenic by 24 times, cadmium by five times, and lead by ten times. The results of the study of economic indicators of growing Hubbard RedBro cross broiler chickens, as well as the chemical composition and quality of carcasses, indicated that there was no significant difference between the floor and cell conditions of keeping. Still, the use of a diet based on eco-feeds contributed to a statistically significant decrease in the concentration of toxic metals in the muscles of the poultry of the experimental groups. As a result, it found that the use of the studied compound feed in the diets of broiler chickens increased the indicators of Biosafety and ensured the production of environmentally safe ("organic") poultry meat products.
