The basis for the diets of pigs of different technologies of production and productivity in all areas and forage species are of plant origin, which is associated primarily with their availability. This group consists of feed grain cereals, grain legumes, green coarse, juicy, waste flour and other technical industries and others. Although omnivorous pig feed them digestion features displayed on the feasibility of forming foundations diet of concentrated feed. For industrial production of pork proportion of concentrated feed often 100%. However, partly in used feed feeding that are of poor quality, which in turn worsens their nutritional value and complicates digestion and nutrient absorption of food. Besides the low digestibility of grain mixtures in which a third of organic matter is not absorbed by the animals, lack of nutrients adversely affect the resistance and other reactions, reproductive function and performance. Studying the formative influence of the new feed factor on the structure of the digestive system of animals must pay attention to the morphological features of individual organs as the result of direct exposure to chemicals in the diet of the wall of the gastrointestinal tract. The effect of different doses of probiotic preparation Entero–active  in growing young pigs on morphological indicators of cardiac, fundic and pyloric stomach areas and established its laws. The data indicate a probable thickening of the stomach wall for probiotic action by thickening  muscle and mucous membranes in all investigated areas. The changes have no pathological character, and show an adaptive response to the action of gastric certain doses of the new feed factor.

ABSTRACTSeveral dietary ingredients may affect the bacterial community structure and metabolism in the porcine gut and may therefore influence animals' health and performance. This study investigated the effects of cereal source and calcium-phosphorus (CaP) level in the diet on bacterial microbiota and metabolites, nutrient intake, and gut environment in weaned pigs. Pigs (n= 8/treatment) were fed wheat-barley- or corn-based diets with an adequate or high CaP level for 14 days. Effects on microbiota in the stomach, ileum, and midcolon were assessed using quantitative PCR. Data showed thatEnterobacteriaceae,Campylobacterspp., andHelicobacterspp., which all contain highly immune reactive lipopolysaccharide (LPS), were abundant at all gut sites. Diet effects on bacteria and metabolites were moderate and occurred mainly in the upper gut, whereas no effects on bacteria, fermentation products, and LPS could be observed in the colon. Differences in carbohydrate intake with corn versus wheat-barley diets selectively stimulatedBifidobacteriumin the stomach and ileum. There was a growth advantage for a few bacterial groups in the stomach and ileum of pigs fed the high versus adequate CaP level (i.e., gastricEnterobacteriaceaeand ilealEnterococcus,Bacteroides-Prevotella-Porphyromonas, andCampylobacter). Interestingly, gastrointestinal pH was not affected by dietary CaP level. The present findings demonstrate the stability of the bacterial community and gut environment toward dietary changes even in young pigs. The results on stimulation of gastric and ilealBifidobacteriumby corn diets may be employed in nutritional strategies to support gut health after weaning.

Abstract Diagnosis of the performance of energy was theoretically developed based on the Structural Theory (Valero, Serra and Lozano, 1993), and traditionally Thermoeconomics have usually been applied to the design of power plants and comparison between alternatives. However, the application of thermoeconomic techniques to actual power plants has always to face the generally poor quality of measurement readings from the standard field instrumentation as an unavoidable first step. The proposed methodology focuses on measurement uncertainty estimation and performance calculation by means of data reconciliation techniques, in order to obtain the most confident plant balance upon the available instrumentation. The formulation of the Structural Theory has been applied to a combined cycle, where the Fuel-Product relationships at the component level must be optimally defined for a correct malfunction interpretation. This set of relationships determines the ability to diagnose and the level of the diagnostics obtained. The paper reports the application of the methodology to a 280 MW rated combined cycle, where performance diagnosis is illustrated with results from a collection of actual operation data sets. The results show that data reconciliation yields sufficient accuracy to conduct a thermoeconomic analysis, and how the estimated impact on fuel correlates with physical causes. Hence the feasibility of thermoeconomic analysis of plant operation is demonstrated.

The adverse health effects of high altitude are of considerable importance since they may seriously interfere with working efficiency of an organization that is actively involved with inescapable duties. The objective of the current study is to explore inter-relational dynamics of various HR aspects in HAIA. The HR aspects included are job delay, poor team, motivation, less leave, high working hours, poor decision making, personal stress, family stress, personal discomfort, uncertainty, poor relations, health, accidents, quality and performance. A decision-making trial and an evaluation laboratory have been used to explore the inter-relation dynamics of various factors of HR. The results indicate that personal stress has the highest impact priority which is followed by poor performance, poor team and motivation. Uncertainty, less leave, and high working hours has the least impact priority. It is also found that high working hours, less leave and poor health are the major causes whereas decrease in motivation and poor quality of work are the major results.

Voluntary Food Intake

Immediately following weaning, voluntary food intake in the young pig is low and very variable. This can lead to reduced digestive efficiency and poor physical performance. One approach to try to stimulate intake is to manipulate the physical form of the diet. Previously it has been shown that, contrary to popular belief, young pigs are very adaptable with regards to diet presentation and in particular with respect to pellet size(Edge et al., 2000). Pigs from 10 to 56 days of age would consume a 5.0mm pellet as readily as a 1.8mm pellet with no adverse effects on production variables.

The work aims to study the effect of different doses of the experimental probiotic preparation “Plantarum” when fed to pregnant animals on their reproductive qualities, as well as on the growth and development of young animals. To obtain young animals, four groups of goats were formed in the type of the Saanen breed, 20 heads each. In the first (control) group, the animals received a standard diet, in the diet of the animals of the second, third and fourth groups in the second half of pregnancy, the probiotic preparation “Plantarum” was additionally introduced, containing Lactobacillus Plantarum, Propiobacterium freudenreihii, in dosages from 0.4 to 0.8 ml/kg of body weight per day. From the offspring of the goats of the experimental groups, four groups of 12 goats were formed. The highest percentage of preservation (94%) and the highest business output of kids per 100 queens (150%) were observed in the fourth experimental group (0.8 ml). The goats of the second, third and fourth groups exceeded the body weight of their contemporaries from the control group by 3%, 6.3%, and 8.8%. The highest indices of the absolute increase in body weight by age periods were noted in the fourth group of goats. There were no significant differences in body build indices during the experiment between the goats of the control and experimental groups. Thus, the maximum positive effect was observed with the introduction of a probiotic preparation into the diet of pregnant goats at a dose of 0.8 ml/kg of body weight per day.

The purpose of this study was to investigate the differences between domestic and international students with regards to the variables affecting students’ retention intentions. Altogether, 15 variables related to retention intentions were examined and significant differences were found in six of these variables. Variables related to personal issues (e.g., medical or family difficulties) were of equal importance to both groups, while the importance of institution and performance-centric variables differed between the groups. Social integration, ineffective study skills, difficulty adjusting to college life, poor extracurricular activities, and poor housing arrangements were perceived to be significantly more important by international students, while poor quality of instruction was perceived to be significantly more important by domestic students. Thus, international and domestic students require different retention strategies on the part of the institution.

Infertility is widespread for all species of animals and causes significant economic losses to livestock due to the loss and shortage of offspring, their reduced viability and, consequently, increased morbidity and mortality. Alimentary-deficiency factors are among the commonest causes of infertility, from which A-vitamin deficiency should be singled out. The precursor of vitamin A in the body is carotene, which is an unstable compound which is easily destroyed even under the influence of moderate factors of influence, in connection with which its deficiency is global, especially at the end of the winter – stall period of keeping animals. Accordingly it is the leading etiological factor of retinol deficiency infertility. As a result, the body has two negatives that act in parallel: carotene / vitamin A deficiency adversely affects the organs, the constituent and major functional unit of which is the secretory epithelial cell, and the free radical oxides formed in high concentration are extremely effective in destroying the cells, weakening antioxidant protection. Vitamin A has a significant effect on the reproductive function of animals both directly and indirectly. It is necessary to ensure the structure and functioning of the epithelial tissues of the organs of regulation and performance of sexual function, and therefore the physiological development of the fetus and the course of pregnancy, parturition and postpartum period, ovo- and spermiogenesis, the manifestation of sexual reflexes. Instead, its deficiency underlies the etiology and pathogenesis of retinol deficiency infertility of animals, causing changes in individual indices of homeostasis and prooxidate-antioxidant system, morphostructure of the reproductive and endocrine organs, hormonal status, sperm quality and reproductive function. The consequence is the emergence and development of gynecological, andrological, mammological and perinatal (ante-, intra-, post- and neo-) pathologies. At the same time, the addition of carotene or retinol to the diets of animals or their oral administration in cases of deficiency of vitamin A prevents impaired reproductive function. The study of the features of the etiopathogenesis of retinol deficiency infertility of animals allows programs of complex diagnostics, therapy and prevention to be developed which provide determination of carotene and vitamin A content and replenishment of the organism in cases of their deficiency.
