A total of 80 day old British United Turkeys were subjected to four dietary treatments at varying levels of niacin + yeast. Each treatment had 20 birds of 4 replicates with 5 birds in each replicate. Niacin + yeast (240 ppm niacin + 1.5g/kg yeast and 200 ppm niacin + 1.5 g/kg yeast, at the starter, grower, and finisher phase) showed significant effect on body weight gain, serum Low Density Lipo...

The present study was carried out to examine the effects of a vitamin premix (VP) reduction or withdrawal from finisher diet (29-43 days) on performance, immuno-competence, and characteristics of leg bones and meat lipid oxidation of chickens fed on corn-soybean meal based diet. A total of 900 male broiler chickens (Ross 308) were allocated to five treatment groups (0, 33%, 66%, 100% and 133% V...

A 42-d trial was conducted to compare the effects of probiotic, prebiotic and synbiotic supplements on growth performance, morphology of the jejunum, serum lipid profile and antibody response of broiler chickens. A total of 400 one-d-old male broiler chicks were randomly divided into four treatment groups of four replicates (25 birds per replicate) and fed corn-soybean meal diets. The dietary t...

The aim of this study was to investigate the effect of commercial herbal and chemical medicines on growth performance, serum lipids, intestinal selected bacterial population and intestinal morphology of broiler chickens. In this study, 450 day-old female broiler chickens (Arian strain) were divided into 10 treatments with three replicates of 15 chicks per replicate. On day 14 of the experiment,...

. light is an environmental factor, which has profound influences on broilers performance and frequently overlooked management practices. this study was conducted to compare the effects of different lighting programs on growth, carcass parts and economical performance using 320 one day–old broilers (arian 386) in completely randomized design with 4 treatments and 8 replicates per each treatment...

A study was conducted in a completely randomized design to evaluate the effect of diets formulated on the basis of four critical essential amino acids (lysine, methionine, tryptophan and threonine) on the crude protein requirement, carcass quality, nutrient digestibility, haematological and blood biochemical indices of broiler finisher chickens (28-56 days) reared under tropical environment. On...

one hundred and sixty one-day-old male broilers (ross 308) in a 6-wk period were conducted to 2 groups (with 4 replicates for each group), 20 chicks for a replicate. one group of these chickens was raised in normal temperature (nt) treatment and the other in cold temperature (ct) treatment to induce ascites. at the end of the experiment (wk 6), 2 chickens from each replicate were randomly selec...

This study was conducted using one hundred and eighty (180) day-old broiler chicks, of Anak strain to assess the levels of inclusion of indomie waste meal as a substitute for maize at 0, 25, 50, 75 and 100%. The birds were randomly assigned to dietary treatments using completely randomized design (CRD). Each treatment contained 3 replicates and each replicate had 6 birds. The study lasted for e...

this study was designed to investigate the effects of different levels of tarragon powder on general performance and anetometric, properties of digestive system of male broiler chickens. 200 one-day-old ross 308 male broiler chickens in a completely randomized design with 4 treatments and 5 replicates per treatment and 10 birds in each replicate were used. experimental diets were set on the bas...

an experiment was conducted to evaluate the effect of fennel essence on performance, egg quality and ovarian morphology of commercial laying eggs for ten weeks. in this experiment, one hundred and forty 30-wk-old commercial egg laying type hy-line (w36) were randomly assigned into 4 treatments with 5 replicates and 8 birds per each. treatments were a control (0.0% essence) and diets containing ...
