The purpose of research is beef production efficiensy growing of Black-Motley breed by use of natural drug Nukleopeptid. The research was carried out in SEC-farm «Hero» Chegmagushevskogo district of Bashkortostan. To carry out scientific and economic experience were formed 4 groups of Black-Motley breed calves at the age of 6 months, with 10 heads each. Groups were formed on the basis of analoge groups. The animals of the experimental group II had drug Nukleopeptid subcutaneously at dose of 20 ml, test group III – 25 ml and experimental group IV – 30 ml. The bulls of Group I is control and the drug is not administered them. In setting up the experience of the measurements of animals calves experimental groups had no significant differences in performance. Measurements of all groups of calves naturally increases with age. Studies have revealed that during the period of experience in the animals of group I height at the withers increased by 20.6%, height in the sacrum – by 17.9%, length of the body – by 38.4%, the depth of the chest – 37.3%, the width of the breast – 40.2%, putting backside – 25.5% femus width by 45.9%, whereas test groups in bulls (II-IV), these figures were above 0, respectively, 9-2.0; 0.5-1.4; 1.3-1.8; 0.1-1.0; 2.1-4.5; 1.8-3.6%. Indices body had the same trend. Gobies experimental groups, this applies especially to young animals of group III were more massive with well developed chest and back of the torso. It is proved that the introduction of new drug Nukleopeptid contributes to the meat productivity.

Introduction. Nutrition has a great effect on the quality of life and longevity. Modern food industry pays much attention to the issue of obtaining high-quality and safe livestock products grown without feed antibiotics. The research objective was to study the effect of chamomile extract on a complex of economically useful traits of young rabbits and the qualitative characteristics of meat, as well as to determine the optimal dosage of chamomile extract. Study objects and methods. The experimental research was carried out on the animal farm of the Kuzbass State Agricultural Academy in 2018. Five experimental groups and one control group of young Californian rabbits were formed according to the principle of analogue pairs. Each group included 10 rabbits. From 70-day age, the animals of the experimental group I were supplemented with a phytobiotic feed additive based on wild chamomile extract at a dose of 0.5 g per rabbit per day. In experimental group II, each rabbit received 1 g per day; in experimental group III, it was 1.5 g per rabbit per day; in experimental group IV – 2.0 g per rabbit per day; in experimental group V – 2.5 g per head per day. The experiment lasted 30 days. Results and discussion. The best result was achieved in experimental group II. In the experimental groups, the rabbits demonstrated an increase in hemoglobin. The use of phytobiotic feed additives in the diet did not cause any pathological changes in internal organs. The average live weight at the end of the experiment, compared with the control group, was higher: experimental group I – by 0.82%, experimental group II – by 6.96%, experimental group III – by 5.01%, experimental group IV – by 3.73%, experimental group V – by 2.80% (P ˃ 0.01). An analysis of the chemical composition of rabbit meat after the experiment showed that the water content in the rabbit meat ranged from 76 to 77%, which suggests high water-holding properties. The high dietary qualities of the rabbit meat depended on the content of protein (20–22 wt%) and the low fat content (5–7%). These data make it possible to promote rabbit meat for dietary products. Conclusion. According to the slaughter indicators and the phytobiotic feed additives parameters of meat, the optimal dose of phytobiotic feed additives is 1 g per head per day.

IIrrigation solutions used and time of use has a definite effect on the micro hardness & other physical properties of dentin which in turn have direct consequence on the longevity functional performance of root canal treated teeth. To evaluate the effect of different irrigation solutions on micro hardness of root dentin.Forty extracted single rooted lower premolars were used. After instrumentation all the root halves were randomly assigned into 4groups (n=10) and brought in contact with one of the following irrigants for 5 minutes. Group I: 10 ml of 5% Sodium Hypochlorite (NaOCl).Group II: 10 ml of 17% ethylene diamine tetra-acetic acid (EDTA) followed by 10 ml of 5% NaOCl.Group III: 10 ml of 5% NaOCl followed by 10 ml of 2% chlorhexidine digluconate (CHX).Group IV: 10 ml of 5% NaOCL followed by flush of 10 ml distilled water then by 10ml of 2% CHX. Dentin micro hardness was measured at baseline and after treatment to determine the change in micro hardness, using Vickers tester.Data was analyzed using following parametric tests t-test, ANOVA test and Post Hoc test. Group II ie final irrigation with EDTA showed the highest percentage decrease in micro hardness values, followed by group III, then group IV and the lowest was group I. All groups showed a significant difference between each other (P &#60; 0.05), except group III and IV. The coronal third showed the highest percentage decrease with significant difference between apical and middle thirds (P &#60; 0.05).EDTA with NaOCl causes greatest changes in dentine micro hardness, an intermediate flush with normal saline should be given for prevention of precipitation with NaOCl & CHX.

The article presents the results of studies of the effect of commercial disinfectants registered in Ukraine and allowed for use in beekeeping, as well as a comparative characteristic of their effectiveness in the disinfection of wooden beehive structures. The research was conducted on the basis of the departments of hygiene, sanitation and general veterinary prevention and technology of production and processing of products of small animals of the Lviv National University of Veterinary Medicine and Biotechnology named after S.Z. Gzhytskyi and SLW “Biolab” Food and Veterinary Diagnostic Laboratory (Ostroda, Poland). For research in the spring and summer period 4 groups of test objects were formed on the principle of analogues. Distilled water was used to control disinfection (test group 1). In the second experimental group for disinfection used “Brovadez-20” (active substance benzalkonium chloride 0.5%), in the third experimental group гру “Vetox-1000” (active substance hypochlorite 0.3%) and in the fourth experimental group – “Sumerian silver”(active ingredient of 10% citrate of Argentum citrate). In a comparative analysis of the effectiveness of the disinfectants of the II, III and IV groups, the growth of gram-positive (Streptomyces badius, Curtobakterium) and gram-negative bacteria (Xanthomonas hyacinthi, Pseudomonas alcaligenes, Acidovorax defluvii) was detected, respectively, among the endophores. In the current literature, information on the threat to the health of the honey bee detected by microorganisms is missing. According to the research, certain differences between the effectiveness of disinfectants have been established. It was found that the total microbial number (BMI) was 0.15% in group II, 0.16% in group III and up to 0.10% in group IV relative to control. It was found that the Sumer silver disinfectant at 10% concentration provides the best bactericidal effect (P < 0.001). In a comparative intergroup analysis of the effectiveness of disinfectants, it was found that in the conditions of the experiment, the level of bactericidal activity was the highest in the experiment with the SMC in the case of the use of “Sumer silver” was 32.3% and 34.4% better compared to “Brovades-20” and “Vetox-1000”, respectively. The use of “Sumerian silver” allows you to get the desired result 10 and 4 times faster than the disinfectants “Brovadez-20” and “Vetox-1000” respectively.

This study examines the levels of acylated and desacylated ghrelin, preptin, leptin, and nesfatin-1 peptide changes related to the body mass index (BMI). The subjects were allocated to 5 groups depending on their BMIs as follows: Group I (BMI <18.5 kg/m2); Group II (BMI 18.5–24.9 kg/m2); Group III (BMI 25–29.9 kg/m2); Group IV (BMI 30–39.9 kg/m2); Group V (BMI >40 kg/m2). Serum acylated and desacylated ghrelin, preptin, and leptin levels were measured by the enzyme-linked immunosorbent assay (ELISA) and nesfatin-1 was measured by the enzyme immunoassay (EIA). Desacylated ghrelin levels showed a gradual and statistically significant drop from Group I to Group V, while preptin and leptin levels exhibited a gradual and significant increase from Group I to Group IV. Serum nesfatin-1 levels gradually, but not significantly, increased from Group I to Group III and showed a significant decrease in Groups IV and V. In conclusion, leptin, preptin, and acylated ghrelin (AG) levels increased with higher BMI, whereas desacylated ghrelin (DAG) decreased and nesfatin-1 showed no clear relationship to BMI.

The used of monosodium glutamate (MSG) oftenly found in almost every food that we consumed everyday. It suggested that MSG can increase appetite, can caused intake much foods, and increased the bodyweight. The aim of study is to prove the changes that occur in male mice by induce of MSG. The experimental study used 24 male mice, 30-45 gram, 12-14 weeks divided into 4 groups, ie group-I (negative control/placebo given aquadest 0.2 cc/20gBW mice); group-II, MSG with the dose of 5 mg/gBW mice); group-III, MSG with the dose of 10 mg/gBW mice and group-IV, MSG with the dose of 20 mg/gBW mice. All of these treatments were administered orally for 14 days. Permanent cervical fracture execution was performed at the end of the study. The body weight measured in pre and post treatment. The significant difference of data between different groups was compared by ANOVA followed by Tukey test. The compared of between pre –post treatment used paired test to analyze the changes of bodyweight This study proved that the comparison of mean values ± SEM of body weight between groups were not significantly different; group I (39,83±3,26), group II (39,33±2,04), group III (38,00±1,39) and group IV (38,33±1,76) (p = 0.930) and the changes of bodyweight pre and post treatmen also not significantly different, whereas p > 0.05. The study concluded that no changes in the body weight between groups and pasca induced by MSG. In the future studies, we consider to examining the effects MSG with longer of duration and more variations doses in MSG.

Background: Astaxanthin suppressed obesity in rats fed with high-fat diet(HFD) via the restriction of adipose tissue build-out, therefore, improving insulin sensitivity and inflammation. Metformin reduces insulin resistance and may reduce weight. Aim: Investigation of the effects of astaxanthin and metformin in obesity prompted by a high-fat diet. Objective: The present article investigates the effects of astaxanthin and metformin in obesity prompted by a high-fat diet in rats through measuring miRNA222 and 378. Materials: The rats were classified into four classes containing ten albino rats each: Group I(Normal group): nourished with ordinary diet for 8weeks. Group II(Control positive): nourished with a high-fat diet for 8 weeks. Group III: nourished with astaxanthin(50mg/kg)(1/40 LD50) orally plus a high-fat diet for 8weeks. Group IV: nourished with metformin (500mg/kg) orally plus a high-fat diet for 8 weeks. Results: Astaxanthin and metformin have anti-obesity and antioxidant actions and significantly decreased the weight of the body, glucose, insulin, triglycerides, total cholesterol, triglycerides and leptin, as well as plasma calprotectin & IL-6 and increased HDL-C and adiponectin. The liver TNF-αgene expression, adipose tissue miRNA222 and miRNA378 expression were decreased compared to HFD control rats. Discussion and conclusion: Astaxanthin has regulated the aberrant expression of miRNA222 and 378 that may be related to hyperlipidemia and insulin resistance. Accordingly, astaxanthin deserves a clinical trial in the future due to its effects on miRNAs involved in obesity.
