Öğe Effects of dietary black cumin seed (Nigella sativa L.) on performance, egg traits, egg cholesterol content and egg yolk fatty acid composition in laying hens(WILEY-BLACKWELL, 2009) Yalcin, Sakine; Yalcin, Suzan; Erol, Handan; Bugdayci, K. Emre; Ozsoy, Buelent; Cakir, SerkanBACKGROUND: The objective of this study was to determine the effects of dietary black cumin seed on performance, egg traits, egg cholesterol content and egg yolk fatty acid composition in laying hens during a 12 week period. For this purpose a total of 160 Lohmann Brown laying hens 36 weeks of age were allocated to four dietary treatments with one control group and three treatment groups. Black cumin seed (Nigella sativa L.) was used at the level of 5, 10 and 15 g kg(-1) in the diets of the first, second and third treatment groups, respectively. RESULTS: Dietary treatments did not significantly affect body weight, feed intake, egg production, egg quality characteristics and blood parameters. Diets containing 10 and 15 g kg(-1) black cumin seed increased egg weight (P < 0.01), improved feed efficiency (P < 0.01) and decreased egg yolk cholesterol, saturated fatty acids (% of total fatty acid methyl esters) and the ratio of saturated to unsaturated fatty acids (P < 0.05) compared to the diet of control group. CONCLUSION: Dietary black cumin seed at the level of 10 and 15 g kg(-1) had beneficial effects on egg weight, feed efficiency, egg cholesterol content and egg yolk fatty acid composition. Therefore it can be used at the level of 10 and 15 g kg(-1) in the diets of laying hens. (C) 2009 Society of Chemical IndustryÖğe Effects of dietary dried baker's yeast on the performance, egg traits and blood parameters in laying quails(SPRINGER, 2009) Yalcin, Sakine; Oguz, Fatma; Gueclue, Berrin; Yalcin, SuzanThis study was conducted to investigate the effects of dietary dried baker's yeast on laying performance, egg traits and some blood parameters of quails. In the experiment a total of 342 Japanese quails (Coturnix coturnix japonica) aged ten weeks were equally divided into six groups of 57 (three replicates of 19 quails each). Six levels (0, 4, 8, 12, 16 and 20%) of dried baker's yeast were included in isonitrogenous and isocaloric diets. The experimental period lasted 14 weeks. At the end of the experiment, there were no significant differences among the groups in body weight, feed intake, protein intake, egg production, feed efficiency, egg yolk index and egg haugh unit. Blood serum levels of total protein, triglyceride and cholesterol were not affected by dietary dried baker's yeast. Diets containing 4 and 8% of dried baker's yeast increased the egg weight significantly (p < 0.01). The inclusion of dried baker's yeast at the level of 20% to the diets reduced egg shell thickness and egg albumen height. It is concluded that dried baker's yeast can be used up to 16% in the diets of laying quails without adverse effects on the measured parameters.Öğe Effects of dietary inactive yeast and live yeast on performance, egg quality traits, some blood parameters and antibody production to srbc of laying hens(KAFKAS UNIV, VETERINER FAKULTESI DERGISI, 2015) Yalcin, Sakine; Yalcin, Suzan; Sahin, Aydin; Duyum, Hayrettin M.; Calik, Ali; Gumus, HidirThis study was carried out to determine the effects of dietary inactive yeast and live yeast on performance, egg quality traits, some blood parameters and antibody production to sheep red blood cell (SRBC) of laying hens during 16 weeks. A total of 96 Hyline Brown laying hens were allocated into one control group and three treatment groups each containing 24 hens. Each group had six replicate groups of 4 hens. A basal diet was supplemented with 1 g/kg inactive yeast (yeast autolysate, InteWall, Saccharomyces cerevisiae), 0.5 g/kg live yeast (InteSacc, Saccharomyces cerevisiae) and 1 g/kg inactive yeast + 0.5 g/kg live yeast in the diets of the first, second and third treatment groups, respectively. At the end of the study the results indicated that dietary treatments did not affect feed intake, interior and exterior egg quality characteristics. Dietary inactive yeast supplementation improved hen-day egg production (P=0.024) and feed conversion ratio (P=0.017) and decreased egg yolk cholesterol concentration (P=0.013). Antibody titers against SRBC and blood serum parameters were not affected by dietary treatments. The significant interaction was found in egg yolk cholesterol concentration (P=0.032) between inactive yeast and live yeast. As a result dietary inactive yeast at the level of 1 g/kg had beneficial effects in laying performance and in low cholesterol-egg production.Öğe Effects of dietary sepiolite on performance, egg quality and some blood parameters in laying hens(ANKARA UNIV PRESS, 2016) Yalcin, Sakine; Eser, Handan; Onbasilar, Ilyas; Yalcin, Suzan; Karakas Oguz, FatmaThe aim of this study was to determine the effects of dietary sepiolite on performance, egg quality, egg yolk cholesterol content and some blood parameters of laying hens during 22 weeks period. For this purpose a total of 135 Lohmann Brown laying hens, 38 weeks of age, were allocated to one control group and two treatment groups. Sepiolite was used at the level of 0, 0.5 and 1% for the diets of control group and the first and second treatment groups, respectively. Dietary sepiolite supplementation did not significantly affect feed intake, egg production, egg weight and feed conversion ratio. The values of egg breaking strength (p<0.01) and egg shell thickness (p<0.05) were increased, egg yolk cholesterol was decreased (p<0.05) by the usage of 1% sepiolite in the diet. Dietary treatments did not significantly affect egg shape index, egg albumen height, egg albumen index, egg yolk index and egg Haugh unit. Dietary sepiolite at 1% reduced cholesterol and triglyceride in serum (p<0.05) and increased total protein in serum (p<0.01). It was concluded that dietary supplementation of 1% sepiolite was effective feed additive in layer feeding due to the reduction in egg yolk cholesterol and improvement in egg shell quality.Öğe Effects of dietary yeast cell wall on performance, egg quality and humoral immune response in laying hens(ANKARA UNIV PRESS, 2014) Yalcin, Sakine; Yalcin, Suzan; Onbasilar, Ilyas; Eser, Handan; Sahin, AydinThe objective of this study was to determine the effects of dietary yeast cell wall (YCW) on performance, egg quality, some blood parameters and humoral immune response of laying hens during 26 wks period. For this purpose a total of 225 Hyline Brown laying hens, 39 wks of age, were allocated to one control group and four treatment groups. Basal diet was supplemented with YCW derived from bakers yeast Saccharomyces cerevisiae (InteMOS) at the level of 1, 2, 3 and 4 g/kg in the diets of the first, second, third and fourth treatment groups, respectively. Dietary treatments did not significantly affect body weight, feed intake, egg production, egg weight, feed conversion, and egg internal and external quality characteristics. YCW supplementation at the level of 1 and 2 g/kg decreased egg yolk cholesterol level as mg per g yolk (P < 0.05). Blood serum levels of cholesterol and triglyceride were decreased with the dietary inclusion of YCW at the level of 2, 3 and 4 g/kg (P < 0.01). Dietary YCW supplementation increased antibody titres to SRBC (P < 0.01). As a result dietary YCW at the level of 1 and 2 g/kg had beneficial effects in the production of low cholesterol eggs and improvement in humoral immunity response.Öğe Effects of dietary yeast cell wall supplementation on performance, carcass characteristics, antibody production and histopathological changes in broilers(KAFKAS UNIV, VETERINER FAKULTESI DERGISI, 2014) Yalcin, Sakine; Yalcin, Suzan; Eser, Handan; Sahin, Aydin; Yalcin, S. Songul; Gucer, SafakThis study was carried out to determine the effects of dietary yeast cell wall supplementation on growth performance, carcass traits, antibody production to sheep red blood cells (SRBC) and histopathological changes in broilers. A total of 272 Ross 308 male broiler chicks aged one day were allocated into one control group and three treatment groups each containing 68 chicks. A basal diet was supplemented with 0, 1, 2 and 3 g/kg yeast cell wall (InteMos) to obtain dietary treatments. The experimental period lasted 6 weeks. Dietary yeast cell wall increased body weight gain during the first three weeks (P<0.001). Feed conversion during the first three weeks (P<0.001) and during the overall experimental period (P<0.01) were improved with the dietary supplementation of yeast cell wall. No differences were observed in feed intake, carcass yield and the relative weights of gizzard, liver and heart. Yeast cell wall supplementation decreased the relative weight of abdominal fat (P<0.05) and increased antibody titres to SRBC (P<0.01) in broilers. Control and treatment groups had similar histological grade; hepatic lobular inflammation, steatosis and cell ballooning scores and, cardiac steatosis. It is concluded that yeast cell wall was an effective feed additive in broiler feeding due to the increased growth performance, increased humoral immune response and the reduction in abdominal fat.Öğe Effects of grit supplementation to diets containing maize and barley as cereal grains on performance and slaughter characteristics in broilers(KAFKAS UNIV, VETERINER FAKULTESI DERGISI, 2019) Eser, Handan; Yalcin, Sakine; Onbasilar, Ilyas; Burcak, Ender; Yalcin, SuzanThe aim of this study was to determine the effects of grit supplementation to the diets containing maize and barley as cereal grains on performance and slaughter characteristics in broilers. In the experiment, a total of 160 Ross 308 male broiler chicks were allocated to 2 experimental groups with 4 replicate pens containing 20 birds per each for 5 weeks of experimental period. Granite grit was added at the level of 0 and 0.8% to the basal diets containing barley and maize as cereal grains for control and treatment groups, respectively. Granite grit supplementation had no significant effect on final body weight and body weight gain. Feed intake during the experiment was significantly reduced by grit supplementation (P<0.05). However, no significant differences were observed with the feed conversion ratio. Granite grit supplementation to the diets of broilers increased the relative weight of gizzard (P=0.001) and decreased the relative weight of abdominal fat (P <0.05). Dietary treatments did not affect blood serum total cholesterol and triglyceride. In conclusion, granite grit supplementation might be used in broiler nutrition due to having increment in the relative weight of gizzard and reduction in relative weight of abdominal fat.Öğe Effects of sepiolite usage in broiler diets on performance, carcass traits and some blood parameters(KAFKAS UNIV, VETERINER FAKULTESI DERGISI, 2012) Eser, Handan; Yalcin, Sakine; Yalcin, Suzan; Sehu, AdnanThis study was carried out to determine the effects of dietary sepiolite on performance, carcass traits and some blood parameters of broilers. A total of 204 daily Ross 308 female broiler chicks were allocated into one control group and two treatment groups each containing 68 chicks. Sepiolite was used at the level of 0%, 0.5% and 1% for the diets of control group and the first and second treatment groups, respectively. The experimental period lasted 6 weeks. Supplemental sepiolite improved body weight (P<0.01) and overall body weight gain (P<0.05). No differences were observed in feed intake, feed efficiency, carcass yield and the relative weights of gizzard, liver, heart, spleen and Bursa Fabricus among groups. The relative weight of abdominal fat and the levels of serum cholesterol and serum triglyceride were reduced with 1% sepiolite inclusion in the diet. Blood serum levels of total protein were not affected by sepiolite. It is concluded that 1% sepiolite in the diets of broiler increase body weight gain and reduce the relative weight of abdominal fat and the levels of serum cholesterol and triglyceride.Öğe The Nutritive Value of Live Yeast Culture (Saccharomyces cerevisiae) and Its Effect on Milk Yield, Milk Composition and Some Blood Parameters of Dairy Cows(ASIAN-AUSTRALASIAN ASSOC ANIMAL PRODUCTION SOC, 2011) Yalcin, Sakine; Yalcin, Suzan; Can, Pinar; Gurdal, Arif O.; Bagci, Cemalettin; Eltan, OnderThis study was conducted to determine the nutritive value of live yeast culture (RumiSacc, Saccharomyces cerevisiae) and to investigate its effects on milk yield, milk composition and some blood parameters in lactating cows. Six multiparous Holstein cows were allocated to two groups of three cows and assigned randomly to one of two diets in a cross-over experiment. Daily 50 g RumiSacc was top dressed at the p.m. feeding for the treatment group. RumiSacc supplied a high protein and energy with high organic matter digestibility values (83.35%) determined by in vitro enzymatic analysis. Yeast culture supplementation significantly increased milk yield, tended to increase fat yield, protein yield and lactose yield of milk. Methylated fatty acid level of 18:3 (n-3) in milk fat was increased by yeast culture supplementation. The concentrations of methionine, phenyalanine, tyrosine, tryptophan and taurine were significantly increased with dietary inclusion of yeast culture. Live yeast culture supplementation did not affect other performance characteristics, milk quality characteristics and blood parameters. As a conclusion live yeast culture (RumiSacc, Saccharomyces cerevisiae) had high nutritive value and positive effects on milk production and some milk quality characteristics in lactating cows under field conditions.
