The aim of the study was to examine the protein turnover and morpho-biochemical readings of growing geese taking “Vitammin” feed additive. The control banding poultry received basic diet, the 1st experimental group received the diet with the addition of “Vitammin” in a dose of 0.2 ml/l of water, the 2nd experimental group – 0.5 ml/l of water. The research conducted showed that the use of “Vitammin” feed additive contributed to high-turnover rates and, consequently, improved the oxygen supply to organs and tissues in contrast to the control banding. In case of increasing the dose the additive it was noted that the rates of aerobic respiration increased as well, which is typical for the augmentation of metabolic processes and, subsequently, productivity.

Изучен способ нормализации обменных процессов и повышения продуктивности молочных коров при использовании комплекса биологически активных веществ. Эксперимент проведен на коровах голштинской породы (n=12) с продуктивностью за предыдущую лактацию 9000 кг молока. За 20 дней до отела и в течение 65 дней после коровы опытной группы получали комплексную кормовую добавку (ККД), включающую минерал шунгит, холин в «защищенной» форме, пробиотик «Целлобактерин+» и жмых льняной, в количестве 200 г на голову в сутки в смеси с концентратами. Для изучения обменных процессов в организме коров (n=5) в конце опыта отобраны пробы крови и определены основные биохимические показатели. Для оценки продуктивных качеств проводили контрольные дойки. Отмечено повышение в крови коров опытной группы концентрации общего белка на 2,8%, глюкозы — на 26,8% (P≤0,01), фосфолипидов — на 15,2% (P≤0,05), снижение мочевины на 23,6% (P≤0,05), билирубина — на 23,8% (P≤0,01), активности АЛТ на 13,11 (P≤0,05), АСТ — на 14,6% (P≤0,05). Использование ККД позволило снизить и привести в норму активность ферментов: лактатдегидрогеназы (ЛДГ), гаммаглутаминтрансферазы (ГГТ), креатинкиназы. Повышение интенсивности обменных процессов и нормализация показателей, характеризующих работу печени с использованием в питании комплекса биологически активных веществ ферментно-пробиотического, антиоксидантного и липотропно-гепатопротекторного действия, привело к повышению молочной продуктивности. A method of normalizing metabolic processes and increasing the productivity of dairy cows using a complex of biologically active substances has been studied. The experiment was carried out on Holstein cows (n = 12) with a productivity for the previous lactation of 9000 kg of milk. 20 days before calving and within 65 days after the cows of the experimental group received a complex feed supplement (CFS), including the mineral shungite, choline in a "protected" form, the probiotic "Cellobacterin +" and flaxseed cake, in an amount of 200 g per head per day mixed with concentrates. To study metabolic processes in the body of cows (n = 5), at the end of the experiment, blood samples were taken and the main biochemical parameters were determined. To assess the productive qualities, control milking was carried out. An increase in the blood of cows of the experimental group was noted in the concentration of total protein by 2.8%, glucose - by 26.8% (P≤0.01), phospholipids — by 15.2% (P≤0.05), a decrease in urea by 23,6% (P≤0.05), bilirubin - by 23.8% (P≤0.01), ALT activity by 13.11 (P≤0.05), AST — by 14.6% (P≤ 0.05). The use of CFS made it possible to reduce and normalize the activity of enzymes: lactate dehydrogenase (LDH), gamma glutamine transferase (GGT), creatine kinase. An increase in the intensity of metabolic processes and the normalization of indicators characterizing the work of the liver with the use of a complex of biologically active substances of enzymatic-probiotic, antioxidant and lipotropic-hepatoprotective action in the diet led to an increase in milk productivity.

Abstract The accumulation of protein aggregates and dysfunctional organelles as organisms age has led to the hypothesis that aging involves general breakdown of protein quality control. We tested this hypothesis using a proteomic and informatic approach in the fruit fly Drosophila melanogaster. Turnover of most proteins was markedly slower in old flies. However, ribosomal and proteasomal proteins maintained high turnover rates, suggesting that the observed slowdowns in protein turnover might not be due to a global failure of quality control. As protein turnover reflects the balance of protein synthesis and degradation, we investigated whether decreases in synthesis or decreases in degradation would best explain the observed slowdowns in protein turnover. We found that while many individual proteins in old flies showed slower turnover due to decreased degradation, an approximately equal number showed slower turnover due to decreased synthesis, and enrichment analyses revealed that translation machinery itself was less abundant. Mitochondrial complex I subunits and glycolytic enzymes were decreased in abundance as well, and proteins involved in glutamine-dependent anaplerosis were increased, suggesting that old flies modify energy production to limit oxidative damage. Together, our findings suggest that age-related proteostasis changes in Drosophila represent a coordinated adaptation rather than a system collapse.

Purpose: estimation of the possibility of using a mixture of feed additive "BioGrom SC" and the food antibiotic "Monenzin" for normalizing metabolic processes in highly productive cows in the transit period.Materials and methods. Studies were conducted because of the tribal plant of the Leningrad region. Two groups of animals were selected on the principle of analogs (experimental and control) 20 goals in each. The experimental group of cows 21 days before the calving and for 14 days after the calves were given a mixture of feed additive "BioGrom SC" and the food antibiotic "Monenzin". For the cottage additives, calcium carbonate (chalk) was used as a filler in the amount of 250 g with the addition of 10-15 g. Supplements "BioGrom SC" by 1 head. The mixture was prepared at the rate of 20 goals and a food antibiotic "Monenzin" was added to it at the rate of 100 mg per 1 kg of a mixture of feed additive with filler. The resulting mixture was fed by animals of the experimental group. All animal experimental and control groups take blood for 21 days before the hotel. The total protein, beta hydroxy acid, acetoacetic acid, alkaline blood reserve, calcium-phosphoric ratio, glucose is determined. At the end of the transit period on the 21st day of lactation, the blood of animal control and experimental groups was repeatedly investigated.Results. In the cows of the experimental group, in comparison with the cows of the control group at the end of the transit period, a decrease in such biochemical indicators was observed as beta hydroxy acid (a decrease to 0.84 ± 0.03 mmol / l), acetoacetic acid (decrease to 0.4 ± 0, 04 mmol / l). The animals of the experimental group decreased the content of the general protein (77.0 ± 0.08 g / l). Also, the data of the backup alkalinity of blood (acidose indicator) are within reference values. Calcium phosphorus ratio was also within the normal range.Conclusion. Introduction to the diet of a mixture of feed additive "BioGrom SC" and food antibiotic "Monenzin" normalize some biochemical blood indicators in cows in the transit period. At the same time, without correction of metabolic processes, cows are observed ketosis and acidosis, which can lead to premature disposal of animals from herd and as a result of economic losses. Thus, the use of the mixture is shown for the prevention and treatment of acidosis of the scar, metabolic acidosis, ketosis in cattle of the dairy direction of productivity.

Abstract This paper presents an overview of techniques utilizing natural phytoplankton for the detection of metal-Induced stress in the Great Lakes. Both field and laboratory procedures are designed to evaluate either structural changes or functional response of test organisms. This up-to-date compendium provides a choice of techniques, which permits a holistic assessment of the stress caused by toxic metals. Recently introduced techniques, such as normalized size spectra analysis, flow cytometry, and the evaluation of a continuous-flow system response to metal toxicity, are discussed in more detail to explore their future potential. Owing to their key position in the food web, high turnover rates, abundance, and sensitivity to environmental perturbation, phytoplankton serve as reliable early warning indicators of ecosystem deterioration and its restoration.

Protein homeostasis is an equilibrium of paramount importance that maintains cellular performance by preserving an efficient proteome. This equilibrium avoids the accumulation of potentially toxic proteins, which could lead to cellular stress and death. While the regulators of proteostasis are the machineries controlling protein production, folding and degradation, several other factors can influence this process. Here, we have considered two factors influencing protein turnover: the subcellular localization of a protein and its functional state. For this purpose, we used an imaging approach based on the pulse-labeling of 17 representative SNAP-tag constructs for measuring protein lifetimes. With this approach, we obtained precise measurements of protein turnover rates in several subcellular compartments. We also tested a selection of mutants modulating the function of three extensively studied proteins, the Ca2+ sensor calmodulin, the small GTPase Rab5a and the brain creatine kinase (CKB). Finally, we followed up on the increased lifetime observed for the constitutively active Rab5a (Q79L), and we found that its stabilization correlates with enlarged endosomes and increased interaction with membranes. Overall, our data reveal that both changes in protein localization and functional state are key modulators of protein turnover, and protein lifetime fluctuations can be considered to infer changes in cellular behavior.

Currently, there is a rapid development of commercial salmon farming in Russia, which has grown almost 3 times in terms of production since 2013 and exceeded 116 thousand tons in 2020. In turn, this requires the appropriate development of the feed base and the development of methods for the effective use of fairly expensive fi sh feed. From these positions the involvement of the feed additive “Vinivet”, which is a waste of beekeeping in the feed production for fi sh as a protein additive is relevant. The feed additive “Vinivet” contains bee products such as bee bread and slumgum, a significant complex of vitamins, amino acids, macro- and microelements. The purpose of the work was to assess the influence of the feed additive “Vinivet” on the livability of juveniles, growth rate and feed consumption of rainbow trout of Steelhead salmon breed when growing in a recirculating aquaculture system. For the experiment juveniles with an average juvenile weight of 2,37±0,72 g have been selected, from which the control and 3 experimental groups have been formed. The control group has received a standard starting compound feed as the main diet, the 1st experimental group in addition to the main diet has received the additive “Vinivet” in the amount of 2,5 % of the mass of the main diet, the 2nd experimental group has received 5,0 % of the additive, and the 3rd experimental group in the first week received 2,5 % of the additive, and from the second week of studies the dose of the additive was increased to 5 %. The conducted studies have shown that the inclusion of the feed additive “Vinivet” in the feed when growing juveniles of Steelhead salmon is most advisable by introducing it at the dosage of 2,5 % of the mass of the main diet in the first week of cultivation, followed by the increase in the dose to 5,0 %, which allows achieving the highest fi sh productivity of pools in the recirculating aquaculture system compared to all variants of the experiment and by 24 % compared to the control group.

The reproductive traits of sows are of paramount importance in the production of high-quality pork. The world experience of pig farming shows the need to solve first of all the feed problem. Diets unbalanced in the content of vitamins restrain the manifestation of genetically inherent high prolificacy of sows. The purpose of the research was to study the influence of feeding the vitamin feed additive “LipoCar” on the reproductive traits of sows and the biochemical parameters of blood serum. The results of research on the introduction of vitamin feed additive “LipoCar” into the diet of pregnant sows have been presented in the article. The experiment has been carried out in the production conditions in JSC “Linevsky pedigree farm” on sows of Large White breed. Pregnant sows have received a basic diet, balanced for all the normalized elements of nutrition. Sows of the experimental group in the composition of the basic diet fed the feed additive “LipoCar”. The dosage of the drug “Lipocar” was 2,1 g/head/day. “Lipocar” has been fed for 20 days. The total duration of the experiment was 3 months. When introducing the vitamin feed additive “LipoCar” into the main diet of sows in the second half of pregnancy the increase in the number of piglets in the litter by 1,6-6,8 % and the weight of the litter – by 5,6-56,2 % (P ≤ 0,001) have been revealed in comparison with the control group of animals. There was a higher content of carotene in the blood serum of sows of the experimental group by 50,0 % (P ≤ 0,01), vitamin A - by 48,7 % (P ≤ 0,05), and total protein – by 4,9 % (P ≤ 0,05).
