Publication Effects of probiotic supplementation on broiler growth performance: A meta-analysis of randomised controlled trials(Csiro Publishing, 2023-03-10) Uzabacı, Ender; Yıbar, Artun; UZABACI, ENDER; YIBAR, ARTUN; Veteriner Fakültesi; Biyometri Bölümü; 0000-0002-9634-0055; 0000-0001-9510-5734; ABE-9200-2022; JPL-5273-2023Context. The effects of probiotics on broilers' growth and productivity performance have been reported in many scientific studies, and different results have been found. Aim. This study aimed to assess the effects of probiotics on broiler growth performance via meta-analysis. Methods. In this study, the PubMed database was searched with the keywords "broiler' and "probiotic' and it was determined that 60 of 605 studies were suitable. Average daily gain and feed conversion ratio were used as performance parameters. Publication bias was evaluated with Egger's and Begg's tests. The trim and fill method was applied when even one of these tests was significant. Heterogeneity among studies was assessed using the Cochran Q test. The random effect model was used to estimate effect sizes if heterogeneity was statistically significant; otherwise, the fixed-effect model was used. In addition to evaluating all studies, subgroup analyses were performed depending on study duration, probiotic strain, and the probiotic content. Key results. According to the meta-analysis results, there was a significant difference between the probiotic and control groups in studies lasting 35 days in terms of average daily gain (P = 0.005) and feed conversion ratio (P = 0.002). But only the average daily gain (P < 0.001) value was different between the groups in studies lasting 42 days. According to the probiotic strain, significant differences were found between the probiotic and control groups in terms of both growth parameters examined in studies using mono-strain and multi-strain probiotics. A significant difference was found between the probiotic and control groups in average daily gain values in studies where probiotics containing lactic acid bacteria (LAB) and clostridia were used. Conclusion. In conclusion, this study is a current research that examined the effects of probiotic use in broilers in detail according to more than one factor. Implication. In this study, articles in the PubMed database were examined. The sample size of the study can be increased by scanning other databases with the same keywords.Publication Extended spectrum beta-lactamase activity and multidrug resistance of Salmonella serovars isolated from chicken carcasses from different regions of Turkey(Ankara Üniversitesi, 2015-01-01) Ata, Zafer; Dinç, Gökcen; Yibar, Artun; Mustak, Hamit Kaan; Şahan, Özlem; Ata, Zafer; YIBAR, ARTUN; Veteriner Fakültesi; Gıda Hijyeni ve Teknolojileri Bölümü; 0000-0001-9510-5734; W-7994-2019; ABE-9200-2022This research was conducted to investigate the extended spectrum beta-lactamase activity and multidrug resistance of Salmonella serovars isolated from chicken carcasses. For this purpose, 99 Salmonella isolates from 930 chicken carcasses were tested against 12 different antimicrobials. The resistance rates of Salmonella isolates to antimicrobials were as follows: 35.3% (35/99) to ampicillin, 33.3% (33/99) to tetracycline, 29.2% to amoxicillin-clavulanic acid, 18.1% (18/99) to nalidixic acid, 17.1% (17/99) to chloramphenicol, 16.1% (16/99) to aztreonam, 12.1% (12/99) to trimethoprim-sulfamethoxazole, 4% (4/99) to gentamicin, 1.0% (1/99) to ceftazidime. Of the isolates 46.4% (46/99) were found to be resistant to two or more antimicrobials as a multidrug resistance. Extended spectrum beta-lactamase activity was detected in 1.0% (1/99) of the isolates. Furthermore, S. Typhimurium 26.2% (28/99), S. Infantis 16.1% (16/99), S. Hadar 12.1% (10/99) and S. Branderburg 9.0% (9/99) were found to be the predominant serovars. In conclusion, antimicrobial resistance and also multidrug resistance rates of Salmonella isolates in this study, indicated that monitoring of antimicrobial resistance profiles is important for Salmonella infections to plan treatment strategies.Publication Plasma amylin concentration in suckling goat neonates and its relationship with C-reactive protein, selected biochemical and hormonal indicators(Veterinarni A Farmaceuticka Univerzita Brno, 2015-01-01) Güzel, Saime; Belenli, Deniz; Yıbar, Artun; GÜZEL, SAİME; Belenli, Deniz; YIBAR, ARTUN; Veteriner Fakültesi; Gıda Bölümü Hijyen ve Teknoloji; 0000-0003-0796-5000; AAH-4275-2021; ABE-9200-2022Amylin is a recently discovered neuropeptide hormone that belongs to the calcitonin gene-related peptide family. It is co-secreted with insulin in response to feed intake. In goat kids, neonatal mortality and morbidity seems to be relatively higher than in other farm species. This high mortality and morbidity in goat kids may be associated with underdeveloped metabolism and immune system during the first week of life. The main objectives of this study were to determine amylin concentration and its relationship with some hormones, biochemical indicators and with a general inflammatory marker, CRP (C-reactive protein) in goat neonates. Blood samples were collected from 30 Saanen goat neonates at 20-35 days of age. Plasma amylin and other hormone concentrations were measured by ELISA, whereas serum biochemical indices were analysed by spectrophotometry. The mean values of plasma amylin concentrations were 9.07 +/- 0.25 pmol/l. Plasma amylin concentrations were positively correlated with plasma non-esterified fatty acids, CRP, prolactin, cortisol, insulin; however, a negative correlation was determined between plasma amylin and serum triglyceride concentrations. The current study suggests that amylin contents are strongly associated with circulating concentrations of some hormones and with those of CRP in Saanen goat kids.Publication Effects of a short-term supplementation with liquid oligofructose-enriched inulin on faecal characteristics and selected serum metabolites of healthy saanen kids(Kafkas Üniversitesi, 2015-09-01) Kara, Cağdaş; Meral, Yavuz; Yibar, Artun; Biricik, Hakan; Orman, Abdulkadir; Deniz, Gülay; Yeşilbağ, Derya; Çetin, İsmail; Gençoğlu, Hıdır; Türkmen, İsmet; KARA, ÇAĞDAŞ; Meral, Yavuz; YIBAR, ARTUN; BİRİCİK, HAKAN; ORMAN, ABDÜLKADİR; DENİZ, GÜLAY; YEŞİLBAĞ, DERYA; ÇETİN, İSMAİL; GENÇOĞLU, HIDIR; TÜRKMEN, İBRAHİM İSMET; Veteriner Fakültesi; Gıda Hijyeni ve Teknolojisi Ana Bilim Dalı; 0000-0001-7051-1349; 0000-0001-9138-4422; AAH-4032-2021; ABE-9200-2022; AAG-9134-2021; AAK-5370-2020; HJZ-4775-2023; FFA-7187-2022; DGQ-7149-2022; ISX-0239-2023; JIM-4044-2023; EDZ-7334-2022The objective of this study was to evaluate the effects of a short-term supplementation with liquid oligofructose-enriched inulin on faecal characteristics and selected serum metabolites of healthy Saanen kids. Twenty-four kids (44 days of age) were allotted to a control (CG) or an experimental (EG) group. Each group consisted of 12 kids. Each kid in EG was supplemented with 0.8 and 1.6 g/d of oligofructose-enriched inulin from day 1 to 5 and from day 6 to 15, respectively. Liquid oligofructose-enriched inulin supplementation did not affect faecal score and pH (P > 0.05). Faecal acetate, propionate and total SCFA concentrations did not differ (P > 0.05) between CG and EG, whereas faecal butyrate concentration was higher (P< 0.05) in kids supplemented with liquid oligofructose-enriched inulin. Due to trophic and antiinflammatory effects of butyrate, we hypothesize that oligofructose-enriched inulin supplementation may be useful to help tissue repair and regeneration, particularly during an intestinal infection. Faecal Lactobacillus, Bifidobacterium and Clostridium perfringens concentrations were not affected by oligofructose-enriched inulin supplementation (P > 0.05). Daily dose of oligofructose-enriched inulin tended to increase serum glucose concentrations (P < 0.09, P < 0.08). Serum urea and albumin concentrations were similar between groups (P > 0.05). Serum total protein and globulin levels were lower in EG compared with CG (P < 0.05). During the experimental period lasting for 15 days, there were no differences in growth performance parameters between groups (P > 0.05).
