The objectives of the present study were to examine the level of radiocesium deposit in meat and edible organs of broiler chickens as well as to investigate efficiency of natural sepiolite in reducing 137Cs deposition in meat, liver and gizzard of alimentary contaminated broiler chickens. Broiler chickens (six weeks of age) were fed with the standard diet and each broiler was given a single oral dose of 137Cs, total activity of 3750 Bq. The broilers were divided into two groups (10 broilers per group). The group 1 was control (received only radiocesium). The broilers of the group 2, in addition to radiocesium received natural sepiolite solution (2 g sepiolite per bird). After 24 hours, all broilers, from each group, were stunned and killed. The samples of meat, (breast and legs), liver and gizzard were taken from each broiler, for gamma spectrometry determination of radiocesium activity. After 24 hours of contamination, 56 % of introduced 137Cs radioactivity was deposited in the meat (breast and legs muscles), 1 % in the liver and 2,4 % in the gizzard of broiler chickens 42 days of age. Natural sepiolite demonstrated insufficient protective action. Compared to the control group, percentage reduction (decreasing percentage) of 137Cs deposition in meat was 16%, in liver 5% and in gizzard 12%.

Background/Aim. Fibrin glue is used as a matrix for local application of antibiotics. The aim of this study was to determine whether application of fibrin glue in combination with antibiotics can strengthen collagen production, prevent dehiscence of colon anastomoses due to infection, and reduce frequency of mortality and morbidity comparing to the control group and the group with fibrin glue application. Methods. The adult male Wistar rats divided into three groups were used in the experiment. The group 1 was the control one (after partial colon resection, colonic anastomoses performed were not treated), while to the group 2 and the group 3 were applied fibrin glue and fibrin glue with antibiotics (clindamycin and ceftriaxon) on the site of anastomoses, respectively. Quality of colonic anastomoses were estimated by means of determination of collagen (L-hydroxyproline) amount in the collon wall with anastomoses and histological analysis of this colon segment using light and electronic microscope on the days 5, 7 and 13 postoperatively. Results. The highest morbidity rate was registered in the group 1 (30%), then in the group 2 (13.3%) and the lowest one in the group 3 (3.33%; p < 0,05 vs group 1). Mortality rate was significantly higher in the group 1 than in the group 3 (20% and 0%, respectively; p < 0,05). In the postoperative course, the highest concentrations of collagen in the colon wall on the site of anastomoses, which was confirmed by both light and electronic microscopy, were found in the group 3. Conclusion. The application of fibrin glue with antibiotics on colon anastomoses reduces the number of dehiscence, provides good mechanical protection and shorten the time of anastomoses healing.

AbstractThis study compared the effect of dietary supplementation with an inorganic or organic zinc source on the gut morphology in the jejunum of broilers. One-day-old chickens were fed a basal diet (Control group: BD — 32 mg Zn.kg−1DM), or the same BD supplemented with 30 mg or 70 mg of Zn per kg of DM in the form of ZnSO4.H2O (Group 1: 30 mg ZnSO4; Group 2: 70 mg ZnSO4), and 30 mg or 70 mg of Zn per kg of DM in the form of zinc chelate of glycine hydrate (Group 3: 30 mg Zn-Gly; Group 4: 70 mg Zn-Gly) for 40 days. The villus height was increased in the groups which received 30 mg ZnSO4and 70 mg ZnSO4and or 70 mg ZnSO4, as compared to the BD and 30 mg Zn-Gly. The villus surface was higher in all groups receiving the Zn supplements in comparison to the BD.

The prebiotics are natural or synthetic organic substances that favour the growth of beneficial microorganisms in the gastro-intestinal tract, thus maintaining the animals healthy and productive and subsequently increasing the production performances. The aim of this study was to evaluate the effects of prebiotic products (Actigen and Biotronic Top3) on the main production and consumption indices of broilers. The study was conducted on a 75 broiler chicken Ross-308 hybrids divided in three groups, over a period of 42 days. Group 1(E) received combined feeds with the Actigen prebiotic for 42 days as follows: 0.08% in the starter phase (1-14 days), 0.04% in the grower phase (14-35 days) and 0.02% in the finisher phase (35-42 days). The broilers in group 2(E) were administered feeds containing prebiotic Biotronic Top3 (0.1%) for the whole duration of the study. The broilers in the control group were fed the base feed only. The broilers from all groups were weighed at the beginning and every following week; their average body weight, daily weight gain, feed consumption and feed conversion ratio (FCR) were determined. The use of the Actigen in experimental group 1(E) led to a body mass increase of 11.26%, to an 11.54% higher daily weight gain and to the reduction of the FCR by 2.31% compared to the control group. In Group 2(E) receiving Biotronic Top3, an increase was recorded for the body mass (9.25%) and daily weight gain (9.49%), the FCR being the same as the one recorded in the control group. These results confirm the favourable influence of prebiotics on the production performances of broiler chickens.

Following the 2006 EU ban of antibiotic-based growth promoters, the use of alternative products, such as prebiotics, became a necessity. The goal of this study was to determine the effects of prebiotic products (Actigen şi Biotronic Top3) on meat quality in broiler chickens. The research has been conducted on a number of 75 Ross-308 hybrid broilers, assigned in three groups (25 individuals/group), over a period of 42 days. Group 1(E) was fed with the base diet supplemented with the Actigen prebiotic in a proportion of 0.08% in the first growth phase (days 1-14), 0.04% in the second phase (days 14-35) and 0.02% in the third phase (days 35-42). Group 2(E) received the base feed supplemented with the Biotronic Top3 prebiotic (0.1%) throughout the whole growth period. At the end of the study period, five broilers from every group have been sacrificed to determine meat quality and meat chemical composition. The usage of prebiotics led to an increase of the carcass weight gain of 16.29% in group 1(E) receiving Actigen and 13.49% in group 2(E), fed with Biotronic Top3, compared to the control group. The percentage of superior quality meat (quality I and II) in the carcass was higher by 4.4% in group 2(E) Biotronic Top3 and by 1.67% in group 1(E) Actigen compared to the control group. Following the administration of Actigen and Biotronic Top3 prebiotics, in groups 1(E) and 2(E) the meat quality was improved in groups 1(E) and 2(E), due to an increase in the protein content and a reduction of the fat content. These results confirm that prebiotics administered in the feeds for broiler chickens have favourable effects on the meat production and meat quality.

Purpose. In the present study, we aimed to investigate the effects of tomato powder (TP) on glucose and lipid metabolism, as well as oxidative stress and the NF-κB, mTOR, and Nrf2 pathways during the aging process in healthy rats. Methods and Results. Male Wistar rats were randomly assigned to four groups as follows: (i) Control group 1 (n=15, 3-week old): rats were fed standard diet for 7 weeks; (ii) TP group 1 (n=15, 3-week old): rats were fed standard diet supplemented with TP for 7 weeks; (iii) Control group 2 (n=15, 8-week old): rats were fed standard diet for 69 weeks; and (iv) TP group 2 (8-week old): rats were fed standard diet supplemented with TP for 69 weeks. TP supplementation significantly reduced the hyperglycemia, hypertriglyceridemia, and hypercholesterolemia and improved liver function and kidney function in 77-week old rats compared with the control animals (P<0.05). In addition, TP significantly decreased the serum and liver MDA levels (P<0.003 and P<0.001, respectively) while increasing the activities of liver SOD (P<0.001), CAT (P<0.008), and GPx (P<0.01) compared with the control groups in both 10-week-old and 77-week-old rats (P<0.05). Age-related increases in phosphorylation of NF-κBp65, mTOR, 4E-BP1, and P70S6K were observed in livers of 77-week-old rats compared to those of 10-week-old rats (P<0.001). TP supplementation decreased the expression of NF-κBp65 and activation of mTOR, 4E-BP1, and P70S6K in livers of 77-week-old rats compared to the control animals. Moreover, TP supplementation significantly elevated Nrf2 expression in livers of both 10-week-old and 77-week-old rats (P<0.05). Conclusion. TP ameliorates age-associated inflammation and oxidative stress through the inhibition of NF-κBp65, mTOR pathways, and Nrf2 activation may explain the observed improvement in glucose and lipid metabolism as well as the improved liver and kidney functions.

There is currently almost no poultry holding where avian eimerioses, both monoinvasions and those associated with cryptosporidioses, salmonelloses and colibacte- rioses, are not reported. In view of this, the disease control is an urgent challenge that shall be approached in its entirety, using various eimeriostats, antibiotics and probiotics. Searching for new effective products with broad-spectrum antiparasitic action is one of priorities in avian eimeriosis control. Comparative tests of different combinations of eimeriocidal products, namely solicox + chicktonic, maduvet + tylosin and eimeterm + enrofloxacin, for their treatment and protective effectiveness were carried out under production conditions in broiler chickens of a poultry factory located in the Republic of Dagestan. To perform the tests, four groups of broiler chickens (one control group and three test groups, each comprising 50 chickens) were formed based on the principle of analogues. The treatment and prevention scheme adopted in the said poultry holding was used for the control group chickens. Test group 1 chickens were given solicox at a dose of 2 ml per 1 liter of drinking water in combination with chicktonic (a feed supplement) at a dose of 1 ml per 1 liter of water during 4–5 days. Group 2 chickens were given maduvet at a dose of 3−5 mg/kg of body weight with feed twice and tylosin at a dose of 5 g of powder per 10 liters of water once a day during 5 days; where necessary, the procedure was repeated in 14–16 days. Group 3 broiler chickens were given eimeterm 2.5% at a dose of 7 mg/kg of body weight with water during 2 days in combination with enrofloxacin at a dose of 3 ml per 1 liter of drinking water during 5–6 days. It is shown that a decrease in the number of clinically diseased and dead chickens was observed in the test groups after the use of eimeriocidal products that helped to improve zootechnical parameters of reared broiler chicks. Product extenseffectiveness and intens- effectiveness in different groups of chickens were as follows: Group 1 – 89.2 and 96%, Group 2 – 87.6 and 94%, Group 3 –81.4 and 96%, respectively. The clinical signs of eimeriosis were observed in the control group chickens throughout the entire period of studies, invasion extensity and intensity were 87.6 and 42.6%, respectively.

The present study aimed to investigate the prophylactic effect of Cymbopogon proximus and Alhagi maurorum on Sulfadimidine induced urolithiasis in rabbits . Thirty New Zealand male rabbits were allocated into six equal groups (each of five): Group (1) was used as a negative control. Group(2) were administered sulfadimidine (200mg/kg) by intramuscular injection.Groups(3) and (4) were administered sulfadimidine(200mg/kg) by intramuscular injection and 330mg/kg of Cymbopogon proximus alcoholic and aqueous extracts respectively orally.Groups(5) and (6) were administered sulfadimidine(200mg/kg) by intramuscular injection and 400mg/kg of Alhagi maurorum alcoholic and aqueous extracts respectively orally. The period of experiment was 10 days. Blood and urine samples were collected from rabbits on the 10th day. The results recorded a significant decrease in serum creatinine, urea, uric acid and crystalluria in Cymbopogon proximus and Alhagi maurorum groups compared to sulfadimidine treated group.We conclude that Cymbopogon proximus and Alhagi maurorum have a nephroprotective and antiurolithiatic effects against sulfadimidine induced crystalluria.

Introduction: Removable dentures are used by 20% of the population. These may be accompanied by denture stomatitis in 15-70% of patients. The choice of the optimal cleansing agent for removable dental prostheses is of high significance. Aim: The aim of our research was to study the influence of removable denture cleansing products on the adhesion of microorganisms and yeast. Materials and Methods: We manufactured 144 specimens of standardized round shape with a diameter of 10 mm from 4 types of modern polymeric materials used by prosthetic dentistry to produce removable dentures, 12 specimens of each material were placed into suspensions of bacterial cultures of Staphylococcus aureus, Escherichia coli, Candida albicans, then into “ClearaSept” (Test group 1), “Рrotefix active cleanser” (Test group 2), saline solution (Control group), followed by nutrient media. The adhesion index was calculated and analyzed. Results: There was no reliable lowering of adhesion index of Staphylococcus Aureus to all materials detected in Test group 1 (U=6, p>0.05 for Bio XS; U=8, p>0.05 for Dental D, Denotokeep Peek, Vertex Rapid Simplified). In Test group 2, the adhesion index of Staphylococcus Aureus reliably decreased to all materials compared to the Control group (U=0, p≤0.01). The adhesion index of Candida albicans and Escherichia coli to all materials in Test group 1 had a minor to moderate reliable reduction compared to the Control group (U=0, p≤0.01). Test group 2 showed a significant reliable decrease in Candida albicans and Escherichia coli adhesion index to all materials in comparison with the Control group (U=0, p≤0.01). Conclusion: The research showed an unreliable or minor and moderate reliable decrease in microorganisms adhesion index depending on the microorganism species after treatment of denture material specimens by antibacterial soap “ClearaSept” and a reliable significant decrease in microbial and yeast adhesion after application of Protefix active cleaner solution, which demonstrates a more significant antimicrobial effect in comparison to “ClearaSept” against Staphylococcus aureus, Escherichia coli, and Candida albicans.

The objective of the present research was to assess the dietary supplementation of three formulations of essential oils (EO) in chickens under heat stress (HS). Day-of-hatch Cobb 500 chicks (n = 500) were randomly distributed into four groups: 1. HS control + control diets; 2. HS + control diets supplemented with 37 ppm EO of Lippia origanoides (LO); 3. HS + control diets supplemented with 45 ppm LO + 45 ppm EO of Rosmarinus officinalis (RO) + 300 ppm red beetroot; 4. HS + 45 ppm LO + 45 ppm RO + 300 ppm natural betaine. Chickens that received the EO showed significant (p < 0.05) improvement on BW, BWG, FI, and FCR compared to control HS chickens. Average body core temperature in group 3 and group 4 was significantly (p < 0.05) reduced compared with the HS control group and group 2. Experimental groups showed a significant reduction in FITC-d at 42 days, a significant increase in SOD at both days but a significant reduction of IFN-γ and IgA compared with HS control (p < 0.05). Bone mineralization was significantly improved by EO treatments (p < 0.05). Together these data suggest that supplemental dietary EO may reduce the harmful effects of HS.
