Abstract The article presents the results of research on the realization of the adaptive, productive and reproductive potential of pigs by immunoprophylaxis of transport stress with Pigstim preparations. The transport stress prevention for replacement gilts with immunotropic drugs PigStim-C and PigStim-M contributed to their adaptive and reproductive potential realization by reducing the age of first insemination by 7.7-9.0 days and increasing its fertility, increasing the number of liveborns by 6.8-8.5% and reducing the number of stillborn piglets by 50 and 25%, increasing the viability by 1.72-3.32% and growth rate of piglets during the suckling period by 2.9- 4.0% and reducing the weaning-to-insemination period by 6.4 and 8.5%. The immunoprophylaxis of transport stress in weaned pigs ensured their adaptive and productive potential in long-term growing completion and store feeding period by increasing the live weight of stores by the end of growing completion by 1.66 and 2.55 kg and feeding period by 1.23 and 3.17 kg, reducing the incidence by 5.0 and 4.0% and increasing the viability of the livestock by 2.0%, increasing the effectiveness of therapeutic measures.

The purpose of this work is to realize the adaptive and productive potential of pigs with immunoprophylaxis of transport stress. Analysis of the morbidity and preservation of young pigs for the periods of growth and fattening found that immunotropic preparations PigStim-C and PigStim-M reduce morbidity, reduce recovery time and increase the effectiveness of therapeutic measures. Against the background of immunoprophylaxis, the incidence of pigs during the growth and fattening periods decreased by 4-5 %, the recovery time was reduced by 0.9-1.7 days, and the safety of pigs increased to 99 %, at 97 % in the control group. A more pronounced positive effect of the application of PigStim-C to diseases characterized by respiratory damage was revealed, and PigStim-M – the gastrointestinal tract. Prevention of transport stress by immunotropic preparations PigStim-C and PigStim-M contributed to an increase in live weight of pigs at the end of the growth period by 1.61 and 1.23 kg, respectively, more than control values, and by the end of the fattening period by 2.55 and 3.17 kg. A similar pattern was revealed in the dynamics of average daily increases in live mass. The average daily increases in the live weight of piglets against the background of the use of preparations of the PigStim series during the growth period were higher by 24.6-32.3 g, during the fattening period by 9.4-19.4 g, and on average for the growth and fattening periods by 17.0-21.2 g.

Development of low-growing varieties is one of the prioritized directions in groups selection. Solution of excessive growth in the selection can be solved in today’s conditions by two means: on a polygenic and on a monogenic level. Up until recently such work was performed by research institutes of horticulture in the U.S.S.R. and Russian Federation only on the polygenic level. The analysis is performed for the data of 17 summer studies on the development of complex donors of monogenic determined dwarfness (gene D), high winter hardiness, group fungal disease resistance (scab, leaf spot and Septoria blight) and bright red coloration of pear fruits (gene C). On the first stage of these studies the issue of the development of population of hybrid dwarf types with high adaptive potential in the conditions of the Central Black Earth region of Russia was solved based on a hybridization of the donors of high winter hardiness and fungal disease resistance with the donors of monogenic determined dwarfness which were the descendants of 4th generation of the NainVert variety. As a result, several complex donors were selected. Its use in long-term pear selection programs would make sorting process possible on earlier stages of the ontogenesis and thanks to that would make it possible to halve the size of hybrid funds. Brief description of the complex donors is given.

This experiment was conducted and aimed to reducing mortality and losing the weight of birds transported to the slaughter house through reducing or Transport stress removal and thus to reduce financial losses. 150 birds used almost equal weights that were divided into three treatment groups and by five replicates for each treatment is control treatment (T1) without giving anything and treatment with salicylic acid concentration 1 g / liter of drinking water (T2) and treatment with ascorbic acid (T3) concentration 0.5 g / Liter of drinking water provided 24 hours before its transport. The transport process resulted in a highly significant decrease (P ≤ 0.01) in body weight in treatment T1 as it reached 4.66%, while it reached 1.68 and 1.09% in treatment T2 and T3, respectively. The transport process led to an increase in body temperature, H / L ratio, the concentration of glucose, aspartate transaminase (AST) and alanine transaminase (ALT) in the blood serum, as the transport process led to a very significant decrease (P ≤ 0.01) in the cholesterol concentration, Uric acid, intestinal villi length and crypts depth. T2 and T3 treatments showed their ability to reduce transport stress, especially T3, where they outperformed T1 in most traits. It is concluded from the study that adding ascorbic acid by 0.5 g / L drinking water 24 hours before transporting the chicks to the slaughter house reduces the transport stress and lessen financial losses, so it is recommended to use it.

Abstract A 16-wk growth trial was conducted to examine the effects of dietary replacement of fish meal by defatted soybean meal (SBM) and fermented soybean meal (FSBM) with taurine supplementation on growth performance, nutrient apparent digestibility coefficient (ADC) and biological parameters of pompano fish. The FSBM was produced by fermenting SBM with Lactobacillus spp. Seven isonitrogenous and isoenergetic diets were formulated to replace 35% or 50% of fish meal by SBM or FSBM with taurine supplementation. The diets are denoted as follows: FM, SBM35, SBM35T, FSBM35T, SBM50, SBM50T, and FSBM50T. The FM (the basal diet) contained fish meal as a main source of dietary protein. Taurine was supplemented to SBM35T, FSBM35T, SBM50T, and FSBM50T at the level of 15 g/kg diet. Pompano juveniles with an initial body weight (BW) of 80 g reared in floating net cages were fed the experimental diets twice daily for 16 wk. Results showed that the final BW, weight gain, and feed conversion ratio of fish fed SBM35 and SBM50 were significantly lower than those of fish fed FM (P < 0.05), indicating that the replacement of fish meal by SBM at the rate of 35% in the diet is excessive for pompano. Supplementation of taurine to the SBM-included diets significantly increased growth performance and feed utilization (P < 0.05); however, these diets did not restore the performance back to a level equivalent to that of fish offered the basal diet. Meanwhile, fish fed FSBM35T had comparable growth and feed performances to those fed FM. Hematocrit values, total biliary bile acid levels, whole body lipid contents, and tissue taurine concentrations of fish fed SBM35 and SBM50 were the lowest among the treatments, but these parameters were improved by taurine supplementation and FSBM inclusion in the diet. Taurine supplementation increased lipid ADC, and SBM fermentation slightly enhanced both lipid and protein ADCs of the fish. These findings suggest that the combination of FSBM and taurine supplementation is an effective way to improve growth performance, nutrient digestibility, and biological parameters, and that FSBM with taurine supplementation can replace 35% of fish meal in pompano diets without any negative effects on growth and feed performances in a long-term feeding period.

Fencing wildlife populations can aid wildlife management goals, but potential benefits may not always outweigh costs of confinement. Population isolation can erode genetic diversity and lead to the accumulation of inbreeding, reducing viability and limiting adaptive potential. We used microsatellite and mitochondrial DNA data collected from 640 white-tailed deer confined within a 1184 ha fence to quantify changes in genetic diversity and inbreeding over the first 12 years of confinement. Genetic diversity was sustained over the course of the study, remaining comparable to unconfined white-tailed deer populations. Uneroded genetic diversity suggests that genetic drift is mitigated by a low level of gene flow, which supports field observations that the fence is not completely impermeable. In year 9 of the study, we observed an unexpected influx of mtDNA diversity and drop in inbreeding as measured by FIS. A male harvest restriction imposed that year increased male survival, and more diverse mating may have contributed to the inbreeding reduction and temporary genetic diversity boost we observed. These data add to our understanding of the long-term impacts of fences on wildlife, but also highlight the importance of continued monitoring of confined populations.

Use of endovascular interventions for arterial occlusive lesions continues to increase. With the evolution of the technology supporting these therapeutic measures, the results of these interventions continue to improve. In general, a comparison of techniques for revascularization of iliac occlusive diseases shows similar initial technical success rates for open versus percutaneous transluminal angioplasty. Angioplasty is often associated with lower periprocedural morbidity and mortality rates. Conversely, surgery frequently provides greater long-term patency, although late failure of percutaneous therapies may occur but still can be treated successfully with reintervention. The perpetual buildup of experience with angioplasty and stenting will eventually characterize its role in the management of occlusive disease. This review outlines the current consensus and applicability of endovascular management of iliac occlusive diseases.

Many questions have emerged recently regarding the importance and methodology of analysis of adaptation. Divergent views reflect both problems of definition and more substantive issues of interpretation. Defining the state of adaptation in terms of its contribution to current fitness, rather than origin by natural selection, is essential if natural selection is to be considered anexplanationof adaptation. The context dependency and relativity of fitness apply also to adaptation. Design criteria are essential components of adaptation, but only to the extent that they are subsumed as elements of the causal interactions determining relative reproductive potential. The local, relational, contingent character of adaptation supports only limited reference to improvement. Most long-term patterns of change can be better described as diffusion within a structured design-space than as progressive improvement of design. The analysis of adaptation is part of a broader inquiry into the processes and constraints that control form and the history of changing form. It offers one perspective on how organisms operate on ecological time scales and how their configurations might be maintained or transformed over evolutionary time. Hypotheses concerning adaptation are sometimes tested by reference to predictions concerning the central tendency or trend of some aspect of an anatomical-behavioral system. These can be interpreted with minimal reference to assumptions of optimality if the analysis is viewed in terms of Bayesian inference. However, an alternative and frequently preferable approach to testing relies on limit-oriented predictions. Analysis of adaptation can be visualized as inferring the pattern and nature of interactions comprising the causal plexus that determines fitness. A comprehensive understanding of form and form-change requires that this be integrated with the perspective offered by studies of development, genetics, phylogenetic history, and external perturbations acting on the system.
