Publication Effects of beta vinasse supplementation on performance, meat quality and iliocaecal microflora in quail rations(Hellenic Veterinary Medical Soc, 2022-10-01) Çetin, I.; Cengiz, S. S.; Çetin, E.; Sarpasar, M.; YEŞİLBAĞ, DERYA; ELMACI, CENGİZ; Bursa Uludağ Üniversitesi/Veteriner Fakültesi; 0000-0003-0979-8402The aim of this study was to evaluate the effects of Beta (beta)-vinasse supplementation on the live weight (LW), live weight gain (LWG), feed intake (FI), feed conversion ratio (FCR), carcass yield, meat quality, and ilio-caecal bacteriological flora of quails. A total of 240 5-d-old Japanese (Coturnix coturnix Japonica) quails, including both males and females, were divided into 3 groups 80 quails and treated as follow: a control group (1) with 0 g beta-vinasse/ kg ration; (2) 15 g/kg beta-vinasse and (3) 30 g/kg beta-vinasse. The study lasted for 6 weeks. At the end of the experiment, supplementation with beta-vinasse did not have a significant effect on FI and FCR. Dietary supplementation with 30 g/ kg beta-vinasse significantly (P < 0.05) increased LW (21 d)and LWG (5 to 21 d). The dietary treatment of quails with different levels of beta- vinasse did not affect hot carcass weight, cold carcass weights, hot and cold carcass yields, and breast and thigh pH.The lightness (L*) and yellowness (b*) of breast values were significantly (P<0.05) increased by 30 g/kg supplementation. Different levels of beta-vinasse significantly increased Lactobacillus spp. in faeces. As a result, it was concluded that beta-vinasse (by-product obtained from molasses) can be used in quail diets as an alternative feed source that will meet the nutritional needs of the animal and have positive effects on the digestive system, especially on the intestinal health (an increase in Lactobacillus spp. counts).Publication Use of bromass in broiler rations as a different protein source(Ecole Nationale Veterinaire Toulouse, 2019-01-01) Cengiz, S. S.; Yeşilbağ, Derya; Cetin, I; Güneş, Nazmiye A.; Eren, M.; Topaloğlu, G.; Cengiz, S. S.; YEŞİLBAĞ, DERYA; GÜNEŞ, NAZMİYE; EREN, MUSTAFA; Topaloğlu, G.; Uludağ Üniversitesi/Veteriner Fakültesi/Hayvancılık Bölümü; Uludağ Üniversitesi/Veteriner Fakültesi/Biyokimya Bölümü; 0000-0002-9347-8307; AAI-1930-2021; ABA-8200-2020; AAK-5370-2020; AAC-5057-2020; CJQ-8714-2022; GHN-5009-2022In this study, we aimed to determine the effects of modified vinasse (Bromass) on body weight, body weight gain, feed intake, feed conversion ratio, carcass yield, litter quality, blood serum parameters and broiler performance index. A total of 600 Ross-308 broiler chicks were used in the experiment, and the chickens were divided into the following 4 main groups: control (0 g/kg Bromass), group I (5 g/kg Bromass), group II (30 g/kg Bromass), and group III (60 g/kg Bmmass). Additionally, each of the main groups was divided into 10 subgroups of 15 chickens each. The trial lasted for 42 days. Supplementation with Bromass (5, 30 and 60 g/kg) caused significant (P < 0.05) increases in the average body weight, body weight gain, feed intake, feed conversion ratio, carcass weights, carcass yield and breast yields. Additionally, Bromass supplementation caused more dry litter at a significant level (P<0.05) and significant (P<0.05) decrease in serum cholesterol concentration. The addition of Bromass to the broiler diets resulted in a significant decrease in feed prices (P<0.05) and an important increase (P<0.05) in the broiler performance index values. At the end of the study, we concluded that the addition of Bromass as a different protein source, especially at the 30 g/kg level, caused positive effects and Bromass makes it possible to produce a more profitable broiler.Publication Influence of supplementation with plant extract mixture on growth performance and blood parameters in quail diets(İstanbul Üniversitesi, 2021-09-01) Çetin, İsmail; Karakcı, Deniz; Yeşilbağ, Derya; Korkmaz Turgud, Firdevs; Narinç, Doğan; YEŞİLBAĞ, DERYA; Bursa Uludağ Üniversitesi/Veteriner Fakültesi/Hayvan Besleme ve Beslenme Hastalıkları Anabilim Dalı; AAK-5370-2020This study aimed to investigate the utility of plant extract mixture (PEM) (Sanguinarine, Honokiol and Magnolol) in quail diets as a natural feed additive, on performance and biochemical parameters. PEMs were supplemented in quail diet to determine the effects of the PEM on feed intake (FI), feed conversion ratio (FCR), live weight (LW), live weight gain (LWG), carcass yield (CY), organ weights and blood parameters. A total of 300 quails were separated into four groups of 75 quails each and treated as follows: a control treatment with 0 g/ton PEM to diet; (PEM100) 100 g/ton PEM to diet; (PEM150) 150 g/ton PEM to diet, and (PEM200) 200 g/ton PEM to diet. The results of the research demonstrated that 100 and 150 g/ton concentrations of PEM caused significant (p < .05) improvement in LWG during the starter and grower periods. Liver weight, live weight, and carcass weight were significantly lower (p < .000) in the PEM100 and PEM200 groups than in the control group. The highest superoxide dismutase (SOD) value was in the PEM150 group (p < .05). In conclusion, we can say that the new-generation PEM increases feed consumption because of the flavor of the feed, results in gain in the LW during the development period, and might have positive effects on blood antioxidant parameter (SOD).Publication Evaluation of the effects of different natural dietary feed additives on performance and intestinal histomorphology in quails(Hellenic Veterinary Medical Soc, 2022-07-01) YEŞİLBAĞ, DERYA; Abdullahoğlu, Esra; Ürkmez, Emin; Acar, Aykut; Kara, Mert; Asmaz, Deniz; Bursa Uludağ Üniversitesi/Veteriner Fakültesi.; 0000-0003-0042-4156; O-9669-2018The aim of the present study was to investigate the influence of a commercial probiotic and a commer-cial essential oil blend and their mixture, as a natural feed additive, on growth parameters live weight (LW), live weight gain (LWG), feed intake (FI), feed conversion ratio (FCR), carcass yield (CY) and small intestinal histomorphology of quails. A total of 200 1-day-old Japanese (Coturnix coturnix Japonica) quails, including both males and females, were divided into four groups containing 50 quails and treated as follows: (1) a control treatment without medication (2) 18 g ton-1 probiotic; (3) 300 g ton-1 essential oil blend and (4) 18 g ton-1 probiotic plus 300 g ton-1 essential oil blend. Each experimental group consisted of 5 replicated groups. The results of the research show that the additives added to quail diets do not have a significant effect on the performance parameters of LW, LWG, FI and FCR (P > 0.05). However, sig-nificant differences were found in the CY, which is one of the performance parameters (P < 0.05). A probiotic addition of 18 g ton-1 (treatment 1) to the quail diet resulted in a significant increase in carcass yield (P < 0.05). Moreover, the addition of natural feed additives such as probiotics, essential oil blends and mixture to quail diets caused significant (P < 0.001) increases in villus heights and crypt depth in the duodenum and ileum segments. In addition, significant enlargements were found in the villus surface area in the experimental groups compared to the control group (P < 0.05). In conclusion, in this study, it was determined that the addition of feed additives, which are developed as an alternative to antibiotics to the quail diet did not have a negative effect on performance and caused significant differences in the effective parameters in the evaluation of intestinal health.Publication Juniper oil improves oxidative stability and eggshell and albumin quality of quail eggs(Taylor, 2015-01-02) Cengiz, Şerife Şule; Yeşilbağ, Deryağ; Meral, Yavuz; Çetin, İrene; Biricik, Hakan; Cengiz, Şerife Şule; YEŞİLBAĞ, DERYA; Meral, Yavuz; Çetin, İrene; BİRİCİK, HAKAN; Uludağ Üniversitesi/Veteriner Fakültesi/Hayvan Besleme Anabilim Dalı; 0000-0003-0708-3833; 0000-0002-9217-3034; 0000-0001-7051-1349; B-1526-2018; K-6112-2016; AAK-5370-2020; AAH-4032-2021; DGQ-7149-20221. The aim of this study was to determine the effects of juniper oil (JO) dietary supplementation on the laying performance, egg traits and egg malondialdehyde (MDA) concentrations of quail.2. A total of 400 female Pharaoh quails were equally divided into 4 groups containing 100 quails (5 replicates of 20 quails each). The study included a control treatment with no diet additives, and the treatments were as follows: (group 1) 100mg JO/kg; (group 2) 200mg JO/kg; (group 3) 300mg JO/kg. The experiment was carried out for 60d.3. At the end of the experiment, there were no significant differences in body weight, egg weight, egg mass, egg shape index, yolk colour, egg production, feed consumption or feed efficiency.4. The Haugh unit was increased in groups 2 and 3 compared to the control group. Dietary fortification with JO improved eggshell thickness and breaking strength compared to the control group. Furthermore, the damaged egg ratio was significantly decreased in group 3 compared to the control. The increasing concentration of JO (200 and 300mg/kg) caused a significant decrease in egg yolk MDA concentration after 15 and 30d of storage at 20 degrees C.5. It was concluded that inclusion of JO in layer diets can improve egg quality characteristics in terms of Haugh unit, eggshell thickness and breaking strength. Moreover, supplementation of JO in the diets of quail may enhance the antioxidant status of eggs, and the most effective doses of JO were 200 and 300mg/kg.Publication Effects of dietary calcium, phosphorus and microbial phytase on intestinal morphology in laying hens(TÜBİTAK, 2022-02-04) Güler, Sabire; Aşmaz, Ender Deniz; Varol Kayapunar, Nuray; İşbilir, İhsan; Cengiz, Şerife Şule; Yeşilbağ, Derya; Şanlı, Ahmet Batuhan; Gültepe, Eyüp Eren; GÜLER, SABİRE; Aşmaz, Ender Deniz; Varol Kayapunar, Nuray; İşbilir, İhsan; Cengiz, Şerife Şule; YEŞİLBAĞ, DERYA; Şanlı, Ahmet Batuhan; Bursa Uludağ Üniversitesi/Veteriner Fakültesi/Hayvan Besleme ve Beslenme Hastalıkları Anabilim Dalı.; Bursa Uludağ Üniversitesi/Veteriner Fakültesi/Patoloji Anabilim Dalı.; Bursa Uludağ Üniversitesi/Veteriner Fakültesi/Histoloji ve Embriyoloji Anabilim Dalı.; 0000-0001-6468-8535; 0000-0002-1062-332X; 0000-0003-0708-3833; JHX-2027-2023; HPG-0648-2023; GXM-5514-2022; FCB-0607-2022; B-1526-2018; AAK-5370-2020; HJQ-8836-2023Different challenges are being applied in poultrthe y industry in order to protect animal health and to increase immunity and production. The supplementation of microbial phytase is essential in terms of both reducing the inorganic phytase rate and contributing to the absorption of other minerals. In this study, a newly isolated microbial phytase was added at different concentrations to the diet together with calcium (Ca2+) and available phosphorus (AP), and the effects of this supplementation on intestinal absorption capacity and Ca2+ binding capacity were investigated via morphological measurements and immunohistochemical examination of the duodenum and ileum. For this purpose, 90 Lohmann LSL-White laying hens were divided into three main diet groups: 1. Standard Ca2+ and AP (Ca+AP), 2. Standard Ca2+ and low AP (Ca+low AP), and 3. Low Ca2+ and low AP (low Ca+low AP). These three groups were further divided into three phytase subgroups each (without phytase [Phy-], commercial phytase [CP] and microbial phytase [MP]). At the end of the experiment, animals were euthanized, and duodenum and ileum samples were fixed and processed for histological examination. Villus height, crypt depth, total mucosa thickness, and villus width were measured and villus height: crypt depth ratio and villus absorption area were calculated. Caldesmon expression in the duodenum and ileum was also investigated immunohistochemically. The results indicated that villus height, total mucosa thickness, and villus absorption area increased (p <= 0.05) in birds fed with Ca2+ APIMP. Stronger caldesmon expression was observed in the MP treated groups. We concluded that MP produced from Bacillus megaterium EBD 9-1 bacterium increases the utilization of Ca2+ and AP and, thus, can have a beneficial role when these macrominerals are used insufficiently. Ca2+, AP, and MP may have positive effects on the intestinal morphology and absorption area when used at optimum amounts.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; Uludağ Üniversitesi/Veteriner Fakültesi/Hayvan Besleme ve Beslenme Hastalıkları Anabilim Dalı.; Uludağ Üniversitesi/Veteriner Fakültesi/Gıda Hijyeni ve Teknolojisi Anabilim Dalı.; Uludağ Üniversitesi/Veteriner Fakültesi/Zootekni Anabilim 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).
