This study was planned to determine the importance of sepiolite in broiler nutrition. For this purpose a total of 180 Ross 308 male broiler chicks aged one day were used. One control group and two treatment groups were designed for 6 weeks of experimental period. Each group was divided into 10 replicates of 6 chicks each in pens. Sepiolite (Exal T®, Tolsa Turkey) was added at the level of 0, 1 and 2% to the diets of control group and the first and the second treatment groups as topdressed, respectively. Sepiolite supplementation at the level of 1% improved final body weight, weight gain and feed efficiency. Dietary treatments did not affect feed intake, gut pH, carcass yield, relative weight of the liver, kidney, spleen, bursa of Fabricius and carcass parts, footpad score, excreta and litter characteristics. Tibia characteristics, blood parameters and breast meat characteristics were not affected by the usage of sepiolite. Relative weight of the abdominal fat and ileal digesta viscosity were reduced and duodenal villus height, ileal digestibility of dry matter, organic matter and crude protein was increased with the usage of 1% sepiolite. It is concluded that dietary supplementation with 1% sepiolite was an effective feed additive for broiler feeding due to its beneficial effects on growth performance, abdominal fat percentage, ileal digesta viscosity, duodenal villus height and ileal digestibility. © 2017 Elsevier B.V.

This study was designed to determine the effects of using yeast autolysate and black cumin seed in laying hen diets on laying performance, egg traits, some blood characteristics and antibody production to sheep red blood cells (SRBC). A total of 112 Brown Nick laying hens, 23. wks of age, were allocated to one of 4 diet groups in 2 levels of yeast autolysate (0 and 2. g/kg, Saccharomyces cerevisiae, InteWall) and 2 levels of black cumin seed (0 and 15. g/kg, Nigella sativa L.) for 18. wks according to a 2 × 2 factorial arrangement. Each group was divided into 7 replicates of 4 hens each. The diets were formulated to be isocaloric and isonitrogenous. Dietary treatments did not affect body weight, feed intake, egg production, mortality, excreta moisture, interior and exterior egg quality characteristics, egg yolk triglyceride or yolk malondialdehyde concentration. Yeast autolysate supplementation improved (P < 0.05) egg weight and feed efficiency but the usage of black cumin seed in the diets decreased (P < 0.05) egg weight. Dietary yeast autolysate or black cumin seed decreased egg yolk cholesterol level, blood serum levels of cholesterol, triglyceride and aspartate amino transferase (AST) and increased blood serum levels of alkaline phosphatase (ALP) and antibody titers to SRBC. The ratio of monounsaturated fatty acids (MUFA) to saturated fatty acids (SFA) increased with black cumin seed. It is concluded that 2. g/kg yeast autolysate (Saccharomyces cerevisiae) or 15. g/kg black cumin seed (Nigella sativa L.) had beneficial effects on egg cholesterol content and humoral immune response. The usage of yeast autolysate also improved egg weight and feed efficiency. The significant interactions were found in egg yolk cholesterol and anti SRBC titer between the usage of yeast autolysate and black cumin seed. © 2012 Elsevier B.V.
