    The aim of the current study was to evaluate the effects of graded levels of crude glycerine addition to diets on growth and economic performance, carcass yield, organ weights and moisture levels of meat in broiler chickens. For this purpose, a total of 270 one day old male chicks (Ross 308) were randomly divided into 3 equal groups which fed with isocaloric and isonitrogenous diets with graded levels (0%, 5% and 10%, respectively) of crude glycerine. Each of experiment group was constituted by 5 subgroups with 18 birds each. The birds had ad libitum access to feed and water until termination of the experiment at d 42. Results indicated that 5% dietary crude glycerine addition improved body weight, body weight gain and feed conversion ratio compare with birds fed with basal diet at d 42 (P<0.01). Similarly, dietary 10% crude glycerine supplementation also increased growth performance and improved FCR in broiler chickens at 28th and 42nd days of experiment (P<0.05 and P<0.001, respectively). Moreover, birds fed with 5% dietary crude glycerine had showed over 20% higher relative economic efficiency compare than birds fed basal diet. As a conclusion, dietary crude glycerine addition improved growth and economic performance and Feed Conversion Ratio of broilers in both supplementation levels.

    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, Adnan
    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.
