    Effect of salinomycin on broiler performance
    (2006) Demirulus H.; Eratak S.; Kara K.
    In this study, effects of salinomycin on broiler performance were evaluated. Six levels of salinomycin added to feed were tested (0, 1, 3, 5, 7 or 9 ppm, respectively) for 49 days. Increasing the level resulted in a decrease in body weight, feed intake, weight gain and feed efficiency. The highest body and neck weight (1972.5 and 90.9 g) and the best feed efficiency (1.59) were obtained with 1 ppm salinomycin (p<0.05). The best viability rate (96%) was obtained with 3 ppm salinomycin (p<0.05). The highest plucked, carcass, tight, wing, breast and back weight of the group were 1629.1, 1316.9, 399.0, 150.0, 440.0 and 300.7 g, respectively. The highest abdominal fat weight (36.8 g) observed with 7 ppm salinomycin used group (p<0.05). © 2006 Asian Network for Scientific Information.

    Determination of fermentation and digestibility characteristics of corn, sunflower and combination of corn and sunflower silages
    (2008) Demirel M.; Bolat D.; Çelik S.; Bakici Y.; Eratak S.
    This study was conducted to determine in vivo digestibilities and fermentation property of various silages made of green herbage of Sunflower (SF), Corn (C) and corn-sunflower mixtures at different rates [75% corn+25% sunflower (75C25SF), 50% corn+50% sunflower (50C50SF), 25% corn+75 sunflower (25C75SF)] ensiled in 120 1 plastic barrels for 90 days. PH values of C and mixture silages were lower than that of SF silage (p<0.05). Concentrations of lactic, acetic, propionic and butyric acids were higher in SF silage than C silage (p<0.05). Lactic and propionic acid concentrations increased in mixture silages as the sunflower ratio increased, whereas decreases in butyric acid concentration were observed as corn ratio incresed in the mixture (p<0.05). While digestibility of DM, OM, ADF and NDF were high in C silage, digestibility of CP and EE were high in SF silage. The digestibility of DM, OM, ADF and NDF in mixture silages increased with the increases in corn ratio in mixture and digestibility of CP and EE of increased as sunflower ratio increased in mixture. It can be concluded that high quality silages could be obtained from green herbage of corn or sunflower alone, however their nutritive values could be improved if they are mixed at 50% ratio. © Medwell Journals, 2008.

    Effect of various additives and harvesting stages on rumen degradation of sunflower silages
    (2009) Demirel M.; Bolat D.; Eratak S.; Çelik S.; Bakici Y.; Çelik S.; Güney M.
    To study effective degradability (nylon bag technique) of sunflower silage, as influenced by harvesting stage (blooming, milk or dough) or molasses (m) I urea (u) mixture, seven different silage samples for each harvest stage [sunflower (SF) and 6 mixtures (2%mSF, 4%mSF, 2%m+0.5%uSF, 2%m+1%uSF, 4%m+0.5%uSF, 4%m+1%uSF)] were incubated for 70 days in 1 litter jars. The DM and CP effective degradation of SF silage was found to be similar at blooming and milking stage and higher than that of dough stage (P<0.05). The effective degradation of ADF and NDF of SF silage at milking and dough stages was lower than that of blooming stage. The positive effects of molasses and molasses+urea additives on effective degradability were observed. It was concluded that decreased degradability of nutrient matters because of its advanced vegetational stage could be partly compensated by using different amount of molasses and molasses+urea additives. © GSP, India.

    Effect of Herbal Essential Oil mixture on Intestinal Mucosal Development, Growth Performance, and Weights of Internal Organs of Quails
    (Har Krishan Bhalla and Sons, 2014) Çabuk M.; Eratak S.; Alçiçek A.; Tuglu I.
    Abstract: The aim of this study was to examine the effects of herbal essential oil mixture on intestinal mucosal development, weights of the internal organs, carcass characteristics, and growth performance of quail (Coturnix coturnix japonica). A total of 276 quails that were 1 day old were studied. The quails were weighed and divided into 3 groups, each with 4 replicates, consisting of a control, antibiotic (avilamycin 10 mg/kg diet), and the essential oil mixture (EOM) at 48 mg/kg diet. Supplementation with EOM and antibiotic significantly increased goblet cell size and goblet cell number on day 38. Villi height, villi width, and crypt depth were not affected by any treatment. Quails receiving the diet containing EOM and antibiotic were significantly heavier than those fed the control diet on days 28 and 38. No significant effects of the dietary treatments on feed intake were observed. Moreover, addition of EOM and antibiotic to the quail diet resulted in a significantly better feed conversion ratio than that of the control on days 28 and 38. No differences were observed for carcass yield or liver, gizzard, and small intestine weights. Beneficial effects of the EOM were observed in goblet cells of the intestinal mucosa. © 2014, © 2014 Har Krishan Bhalla & Sons.

    Effects of herbal essential oil mixture as a dietary supplement on egg production in quail
    (2014) Çabuk M.; Eratak S.; Alçicek A.; Bozkurt M.
    One hundred and eighty 7-week-old laying quail were fed various diets over a 12-week period. The diets included a control diet (without essential oil mixture (EOM) or antibiotics (ANTs)), a basal diet including EOM (24 mg/kg feed), and a basal diet including an ANT (avilamycin, 10 mg/kg feed). Each treatment comprised 4 replications with 4 cages (15 quail per cage), amounting to 60 quail per treatment group. Diets (in mash form) and water were provided for ad libitum consumption. EOM consisted of 6 different essential oils derived from the following herbs: oregano (Origanum sp.), laurel leaf (Laurus nobilis L.), sage leaf (Salvia triloba L.), myrtle leaf (Myrtus communis), fennel seeds (Foeniculum vulgare), and citrus peel (Citrus sp.). In comparison with the control diet, adding supplements such as EOM and ANTs to the basal diet increased egg production in quail (P < 0.001). However, egg production was similar between EOM and ANT treatment groups. Moreover, there were no differences between the treatment groups with regard to egg weight. Feed intake was not affected by EOM or ANT supplementation, whereas feed conversion ratio was significantly improved by EOM and ANT supplementation. Thus, we concluded that EOM has beneficial effects as a dietary supplement on egg production and feed conversion ratio. © 2014 Metin Çabuk et al.

    Effects of dietary inclusion of lentil byproduct on performance and oxidative stability of eggs in laying quail
    (Hindawi Publishing Corporation, 2014) Çabuk M.; Eratak S.; Basmacioʇlu Malayoʇlu H.
    One hundred and sixty-eight 11-week-old laying quails (Coturnix coturnix japonica) were fed one of the following three diets: (1) control: basal diet with no lentil (Lens culinaris L.) byproduct; (2) inclusion of 10% lentil byproduct; (3) inclusion of 20% lentil byproduct. In the recent years, colour sorting machines are used in order to separate red lentils according to their colours. The goal is to select the items which are discoloured, not as ripe as required, or still with hull even after dehulling of lentil seed. During the sorting, a new byproduct called "sorting byproduct" leftover is obtained. The byproduct is cleaner and is of a higher quality than other lentil byproducts. This experiment was conducted to study the effects of the inclusion of different levels of lentil byproduct on laying quail performance. The experimental treatment included 10% or 20% lentil byproduct in the diet, and this was fed to quails aged between 11 and 22 weeks. The inclusion of 10% and 20% levels of lentil byproduct in the diet significantly increased egg production, but feed intake and feed conversion ratio were not significantly affected. Egg weight decreased significantly following the inclusion of 20% lentil byproduct. The inclusion of lentil byproduct in the diet increased the deposition of yellow yolk pigments and decreased malonaldehyde formation in the yolk. © 2014 Metin Çabuk et al.

    Effects of the Dietary Inclusion of Lentil Byproducts on the Performance, Internal Organs Weight and Carcass Yield of Growing Quails
    (University of Punjab (new Campus), 2022) Eratak S.; Çabuk M.; Alcicek A.
    This study was conducted to investigate the effects of different levels of lentil byproducts on the growth performance, relative weight of internal organ and carcass traits of growing quails. Day-old quails (240; Coturnix coturnix japonica) were randomly divided into 4 treatments, each with 4 replicates: control, 10%, 15% and 20% lentil byproducts—fed to the quails between 1 to 35 days of age. The mash experimental diets were isocaloric and isonitrogenous. No significant effects of the lentil byproduct inclusion level were observed on the mean total feed consumption, feed conversion ratio and body weight. Similarly, the relative weight of internal organs and carcass yield were not significantly affected by lentil byproducts’ inclusion levels. The results indicate that lentil byproducts might be included in the diet of growing quails up to a level of 15% with no negative effects. Copyright 2022 Zoological Society of Pakistan.

    Orange Peel Oil Supplementation in Laying Quail Diet: Effects on Performance and Oxidative Stability of Egg Yolk
    (Fundacao APINCO de Ciencia e Tecnologia Avicolas, 2023) Eratak S.; Guvenc Bayram G.; Semen Z.; Cabuk M.
    The present study aimed to investigate the potential utilization of orange peel essential oil (OPEO), as a natural feed additive in poultry nutrition. The impact of incorporating OPEO into the diets of laying quails was examined with respect to various performance criteria, including feed consumption and efficiency, as well as egg production, weight, and shelf life. A total of 120 female egg quails, aged 16 weeks, were allocated into three main groups, and fed with control rations supplemented with OPEO at levels of 0 mg/kg (control group), 200 mg/kg, and 300 mg/kg. Throughout the study, egg production was monitored on a daily basis, feed consumption was recorded every two weeks, and egg weights were measured twice a week on consecutive days. Moreover, the levels of malondialdehyde, a lipid peroxidation marker, in the egg yolks were quantified. The results indicated that the inclusion of OPEO in quail rations did not exert a significant influence on feed consumption and efficiency. However, OPEO supplementation had a positive impact on egg production and weight, leading to substantial increases in both crucial performance parameters. Furthermore, the study elucidated a statistically significant impact of OPEO on the levels of malondialdehyde in the egg yolks. In summary, the incorporation of OPEO into quail diets showcased remarkable efficacy in significantly augmenting egg yield and weight, while leaving feed consumption unaffected. These results highlight the potential of utilizing OPEO as a natural feed additive to improve the performance and egg quality of laying quails in commercial production systems. © 2023, Fundacao APINCO de Ciencia e Tecnologia Avicolas.
