This pilot investigation aimed at studying the feasibility of using a low dose (0.2%) of dietary microalgae as a means of improving intestinal morphometry, body weight, and selected meat quality parameters in broilers. A total of 72 one-day-old ROSS 308 male chicks were randomly separated into four groups; three experimental pens in which the birds were fed with biomass from Tysochrysis lutea, Tetraselmis chuii, and Porphyridium cruentum over 30 days and a control group. T. chuii and P. cruentum had a positive effect with regard to body weight. In treated animals, duodenal and ileal sections showed characteristic tall and thin villi, with serrated surfaces and goblet cell differentiation. In both sections, values of the villus-height-to-crypt-depth ratio were increased by microalgae ingestion. The thawing weight loss of fillets was reduced in T. chuii-fed animals. The positive effects exerted by T. chuii and P. cruentum on intestinal architecture were associated with the improved body weight. Arguably, these outcomes exhibit the potential of using these species to enhance growth performance in broiler chickens by promoting gut homeostasis and thus nutrient absorption.

The study was conducted to assess the effects of sweet potato leaves, roselle calyces and beetroot tubers on body weight, selected hematological and biochemical parameters in broiler chickens. Eighty four (84) broiler chickens aged four weeks were randomly assigned into six groups of 14 chickens each. The first group (G0) remained as untreated control while the other groups were the treated groups which received 25% of ground sweet potato leaves (G1), rosella calyces (G2), beetroot tubers (G3) and their mixtures (G4 and G5) for 28 days. Following inclusion of these different vegetables, blood samples were collected and analyzed for selected hematological and biochemical parameters on day 0, 7, 14, 21 and 28. Results showed that consumption of the three vegetables caused significant decreases (p < 0.05) in body weight, serum glucose and cholesterol. On the other hand, hemoglobin concentration, packed cell volume (PCV) and total white blood cell (WBC) counts were shown to increase significantly (p < 0.05) compared to the control group. It is concluded that the hypoglycemic and hypocholesteremic effects in chickens following consumption of the three vegetables together with their positive effects on PCV and WBC counts are important qualities which can be utilized in the management of conditions such as obesity, diabetes mellitus, hyperlipidemia and cardiovascular diseases (atherosclerosis and coronary disease) in humans. Further studies in other animals are recommended.

Abstract. In the modern broiler industry, solutions are still being sought to improve conditions or eliminate problems related to issues such as animal welfare, health, and meat quality brought by intensive production systems. Therefore, this experiment was conducted to study effects of perching on growth performance, carcass characteristics, and footpad lesions (FPLs) in broiler chickens. A total of 300 broiler chicks (Ross 308) were distributed into control and perch groups with three replicates including equal numbers of males and females. The perch group contained two single perches in each pen. Analysis of camera records revealed that on average 7.36 % of the birds using perches. Perch use did not have any effect on growth performance (P  >  0.05), but had a positive effect on FPLs (P  <  0.001). Carcass yield and proportions of carcass parts were not affected by perch availability (P  >  0.05). Thigh and breast meat color was less yellow (P  <  0.005) in the perch group compared to the control group, where breast meat color was more red (P  <  0.01). Birds in the perch group had brighter breast meat (P  <  0.001). The weight of livers in the perch group was lower than in the control group (P  <  0.01). These findings suggest that perch use has positive effect on FPLs. The reduction of redness in the breast could indicate that perch use may have a positive effect on breast inflammation. The potential positive effects of adapting perch use to intensive conditions should be further investigated.

Poultry farming holds a special place in ensuring the products that the consumers demand, it provides the population with essential food products,such as eggs and meat,that contain vital micro and macronutrients, proteins, lipids, and vitamins. Therefore, the issues of rational, economically feasible feeding of meat poultry, namely broiler chickens, are an urgent task. It is also essential to find effective methods of their application in order to correct the natural resistance and immune and biological reactivity of birds. The purpose of this research is to study the effect of the biological stimulant-Nucleostim on the growth and development of chickens, hematological, and immunological parameters of the blood of birds.This Biostimulant is a purified bovine spleen extract containing at least 1 mg / ml of low molecular weight peptides (nucleotides and nucleosides) formed as a result of autolysis, using dry whey and diatomite as fillers. Onthe application ofNucleostim, the gain in live weight of chickens was increased by 9.7%. At the end of the experiment, the livability of the chicks of the experimental group treated with Nucleostimcame up to 88%, compared with the 72% of the control group. The use of biostimulant had a stimulating effect on the liver of chickens confirmed by the research results presented in the article, as well as contributed to the development of the thymus in the setting of general dystrophy. Thus, it improved chicklivability and increased body weight gain. The biological stimulant-Nucleostim as an adaptogenic, anabolic, and immunostimulatory agent is promising for finding new drugs that improve the health and productivity of poultry.

The article presents the results of studying the impact of the spore-forming probiotic “Olin” and the prebiotic “Eсofiltrum” on the meat quality of broiler chicken carcasses of the Ross-308 cross. In the course of the research, it has been found that the inclusion of these preparations in the broiler diet has a positive effect on the studied indicators: the pre-slaughter weight increased by 4.3-5.7%, the weight of the gutted carcass by 4.6-6.2%, the muscle weight 4.8-6.5%, the weight of the loin muscles by 5.7-8.2%. The ratio of edible parts to inedible parts is 4.14 in the third experimental group, 4.08-in the second, and 4.04-in the control. Based on the results of the anatomical cutting of broiler carcasses and according to the fatness indicators the poultry carcasses of the third and second experimental groups, 87.5% and 87.2%, respectively, belong to the first grade, and the yield of the first grade carcasses is 86.2% in the control group. Meat products obtained from both the control poultry and the poultry of both experimental groups has no off-aroma odor and taste, the meat is juicy, tender and aromatic. The products obtained from broiler chickens, whose ration includes the probiotic “Olin” and the prebiotic “Ecofiltrum”, do not have any deviations from the established standards and norms. During the research, it has been found that the use of the studied drugs has a positive effect on the meat quality of poultry carcasses. However, broiler chickens receiving the probiotic “Olin” has more pronounced meat qualities.

The reliability of the results obtained in scientific and economic experiments on the study of the effectiveness of the use of various feed components, including biologically active substances in the rearing of broilers needs to be confi rmed in production conditions. The purpose of the research was to study the joint use of enzyme drugs and lecithin in the rearing of broiler chickens. The results of production experiment on the study of the effectiveness of the joint inclusion of enzyme drugs Sunzyme and Sunfyse 5000 as well as lecithin in the diet of broiler chickens of the cross Ross-308 have been presented in the article. Production tests have been carried out under the conditions of the breeding farm “Achkhoy– Martanovsky” in the Chechen Republic. The duration of the experiment was 45 days. For research on the principle of analog groups two groups have been formed: a control group and an experimental group of 1000 heads in each. The broilers of the control group have been fed compound feed prepared in accordance with the growing period and consisting mainly of grain components of local production. The broilers of the experimental group have been fed the same compound feed, but with the addition of two enzyme drugs Sanzyme and Sanfyse 5000 (100 g/t of feed) as well as lecithin (10 g/kg of feed). The results of the production experiment fully confi rmed the data obtained in the scientific and economic experiment. The positive effect of the joint use of the studied enzyme drugs and lecithin has been manifested in all the studied productive traits. In particular, the increase in live weight of broilers increased by 12,1 %, slaughter yield by 3,5 %, the yield of carcasses of the 1st category by 3,0 %. The main economic indicators also found their confirmation: feed consumption per unit of growth decreased by 11,7 %, additional profit was received in the amount of 27308,2 rubles, the level of profitability of broiler rearing increased by 18,4 %.

The aim of this study was to determine the effect of diet supplementation with propolis and/or bee pollen on the performance indicators of broilers. This experimental study was conducted on 200 Ross 308 broilers equally distributed by sex and divided into five groups. Throughout the whole study the control group of chickens was fed feed mixture. Feed mixture fed to the experimental groups of chickens contained additives (propolis and/or bee pollen, each supplement separately or in combination in a certain proportion). The average values of broilers body weight were significantly higher on 7th (p=0.001), 14th, 21st, 28th, 35th (p&lt;0.001) and 42nd (p=0.002) day of feeding in the experimental groups of broilers compared to the control group. The average values of broilers weight gain were significantly higher on 1st (p&lt;0.001), 2nd (p=0.002), 3rd (p&lt;0.001), 4th (p=0.029) and 5th (p=0.009) week of feeding in the experimental groups of broilers compared to the control group. This study has undoubtedly shown that propolis and bee pollen have significant positive effect on performance indicators of broilers.

Objective. In previous studies, cranial electrostimulation (CES) had positive effects on sleep in depressed patients and in patients with vascular dementia. The present study examined the effects of low-frequency CES on the rest-activity rhythm and cortisol levels of patients with probable Alzheimer's disease (AD). Method. It was hypothesised that a decreased level of cortisol would parallel a positive effect of low-frequency CES on nocturnal restlessness. Sixteen AD patients were randomly assigned to an experimental group (n = 8) or a control group (n = 8). The experimental group was treated with CES, whereas the control group received sham stimulation, for 30 minutes a day, during 6 weeks. The rest-activity rhythm was assessed by actigraphy. Cortisol was measured repeatedly in the saliva throughout the day by means of salivette tubes. Results. Low-frequency CES did not improve the rest-activity rhythm in AD patients. Moreover, both groups showed an increase instead of a decrease in the level of cortisol. Conclusions: These preliminary results suggest that low-frequency CES has no positive effect on the rest-activity rhythm in AD patients. An alternative research design with high-frequency CES in AD is discussed.

The objective of this study was to investigate whether melamine (MEL) is biotransformed into cyanuric acid (CYA) in male broiler chickens. The effects of the dietary addition of MEL and CYA alone and in combination on the growth performance and mortality of the chickens were also investigated. The chickens were divided into six experimental groups and were fed diets with an addition of 50 or 100 mg/kg MEL or 50 or 100 mg/kg CYA of diet, with the contaminants added separately or in combination. The control group was fed a diet without MEL or CYA. At the end of the experiment (day 40), samples of liver, kidney and breast and thigh muscles were collected from 12 birds per treatment group and were analysed for the presence of MEL and CYA. This study showed that MEL is biotransformed into CYA in broilers. Higher concentrations of MEL or CYA in the diet increased the presence of their residues in tissues, and the CYA residue concentration was several times higher in the respective tissues than the MEL residue concentration. The dietary addition of MEL and CYA did not affect the mortality rate, feed conversion ratio or body weight of the chickens.

AbstractA total of 608 Ross 308 broiler chickens of both sexes were studied to determine the effect of Lactococcus lactis 847 bacteria compared to probiotic bacteria Lactobacillus delbruecki 838 and Lactobacillus plantarum 837 on body weight, feed consumption and conversion, mortality, dressing percentage, postmortem carcass traits, composition of breast muscle tissue, and blood plasma traits. Feeding diets with bacteria to chickens did not increase body weight at 42 days of age or improve feed conversion compared to control chickens. It significantly reduced chicken mortality compared to the control group, from 3.3% to 1.4% (P<0.01). No significant differences were found in feed consumption and conversion. There were no significant differences in the weight of carcasses and their parts. Lactococcus lactis 847 and Lactobacillus plantarum 837 bacteria significantly increased dressing percentage (P<0.05). Lactococcus lactis 847 significantly increased liver weight (P<0.05). No significant differences were observed in carcass fatness, and in the dry matter, protein and fat content of breast muscles. Feeding diet with Lactobacillus plantarum 837 to chickens significantly decreased plasma triglyceride levels, and feeding diet with Lactobacillus delbruecki 838 and Lactobacillus plantarum 837 significantly decreased the level of high-density cholesterol (P<0.05). In conclusion, Lactococcus lactis 847 bacteria in diet significantly reduce losses due to digestive disorders while having no effect on the quantity and proportion of saleable cuts in the carcass, the composition of breast muscles and basic blood parameters.

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.
