    Effects of dietary sepiolite on performance, egg quality and some blood parameters in laying hens
    (Chartered Inst. of Building Services Engineers, 2016) Yalçin S.; Eser H.; Onbaşilar İ.; Yalçin S.; Karakaş Oğuz F.
    The 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. © 2016, Chartered Inst. of Building Services Engineers.

    Effects of sepiolite usage in broiler diets on performance, carcass traits and some blood parameters
    (Veteriner Fakultesi Dergisi, 2012) Eser H.; Yalçin S.; Yalçin S.; Şehu A.
    This 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.
