twenty eight lactating buffaloes were used in a completely randomized design with 2×2 factorial arrangement of four experimental diets including low protein–low energy (lp-le), low protein–high energy (lp-he), high protein–low energy (hp-le) and high protein–high energy (hp-he). results showed that the hp-he diet recorded the highest digestibility coefficients of cp, ee, nfe, nutritive values, ...

the objective of this study was to investigate the effects of different levels of amino acid and feeding methods on performance and immune system of broiler chickens. experimental design was based on completely randomized design in a factorial arrangement with 3 feeding methods [control (ad libitum feed intake), intermittent feeding (if) and continuous feed withdrawal (fw)), and 2 amino acid le...

In this experiment 240 Hy-Line (W-36) laying hens from 65 to 75 weeks distributed in 5 treatments and 4 replicates (12 birds per replicate) in a completely randomized design were used. The amounts of watermelon skin meal (WSM) used to set the treatments were 0, 0.5, 1, 1.5 and 2% in 1 to 5 experimental groups. The results showed that using WSM up to 2% significantly improved the performance and...

Bread is a particularly important staple food. It can be thus improved using different prebiotics like inulin and resistant starch. Food diets with sufficient prebiotic content can trigger the growth of the remaining microorganisms in the digestive system. These microorganisms are essential for human health. In this study, the effect of different levels of inulin and resistant starch (at levels...

this research was conducted to study the factors affecting establishment, growth and shoot proliferation of persian walnut, genotype z60. explant establishment was studied through a factorial experiment based on a completely randomized design with two factors including culture media (dkw and wpm) and ba concentration (0 (control), 0.5 and 1.0 µm). single-node explants were prepared from the you...
