the purpose of this experiment was to investigate the effect of metabolizable energy (me) levels, feed restriction (fr) intensity and duration in pelleted diet on performance, blood parameters and carcass characteristics in broiler chickens. a total of 480 male ross 308 broilers were used in a 2×2×3 factorial arrangement with 12 treatments and 4 replicates. experimental treatments included: two...

The first experiment evaluated the effects of feeding various levels of Se, two Se sources, and hair color on selenosis responses in growing-finishing pigs. The study conducted in two replicates was a 2 x 6 x 2 factorial arrangement in a split-plot design. Sodium selenite and Se-enriched yeast added at 0.3, 1, 3, 5, 7, and 10 ppm Se served as the main plot and pig hair color as the subplot. A t...

To prevent a premature failure, absorbable magnesium implants must possess an adequate mechanical stability. Among many ways to improve the properties of is by particle reinforcement, such as using carbon nanofiber (CNF). This work reports experimental design for optimum materials and processing CNF-reinforced Mg–Zn composites based on two-level factorial design. Four factors were analyzed: per...
