In order to investigate the effect of phytase and copper supplementaion on growth and carcass composition of common carp (Cyprinus carpio L.), in a completely randomized design with 3 ×2 factorial arrangement with three replicates the experimental diets including three levels of phytase 0, 500 and 1000 (FYT) kg-1 and two levels of copper 0 and 15 mg/kg were tested. Diets contained 0.72 percent ...
in this study, the effects of oleothermal modification on physical and mechanical peroperties of fir wood (abeis sp.) blocks were examined. at first, some blocks of fir wood with 5 × 20 × 120 cm dimensions were prepared. the blocks were treated in soybean oil. the effects of 3 factors such as treatments temperature (180and 200 °c), holding time (12 and 15 h) and initial moisture content of wood...
This research was conducted to investigate the effect of different levels of metabolisable energy and crude protein on performance, carcass characteristics and blood parameters of Japanese quail during grower phase (14-28 d of age). Nine hundreds 14-d-old male birds were used to examine 3 levels of energy (2900, 3050 and 3200 Kcal of ME/Kg of the diet) and 3 levels of protein (21.6, 24 and 26.4...
This study was conducted to determine the effect of inclusion sodium bentonite (SB) in Japanese quails’ diet on performance, carcass traits, blood biochemical status, and meat quality traits. A total 120 seven-day-old quails ( Coturnix coturnix Japonica ) were randomly divided into four groups, with each group containing five replicates, six birds each. SB mixed at concentrations (0, 0.5, 1.0 2...
A six-week trial was conducted to study the effect of decreasing dietary crude protein (CP) level on the performance of broilers in hot climatic conditions. Four experimental rations having CP 23 (control group), 22, 21 and 20%, with optimal amino acid balance were prepared. All the four rations were isocaloric having ME 3200 kcal/kg with Energy: Protein (E:P) 139.0, 146.5, 152.4 and 160 in die...
The effect of Aspergillus xylanase (ASXYL) supplementation to maize-soybean diets on serum aspartate aminotransferase, serum alanine aminotransferase, microbial examination, growth traits, carcass characteristics and meat quality traits of broiler chickens was investigated. Three hundred one-day-old mixed sex “Cobb 500” broiler chicks were allotted to 5 dietary treatments with 5 replic...
The effects of selected herbal dietary supplements on the growth performance and carcass quality of broiler chicken were investigated. Three hundred and eight day-old, male broiler chicks of Indian River strain were randomly allotted to seven experimental diets namely negative control, 0.0125% flavomycin (positive control), 0.1% Moringa leaf powder (MLP), 0.05% Moringa leaf powder, 0.035% Zigbi...
this study aimed to investigate the effect of different levels of silymarin against lead induced oxidative stress in broiler chickens. therefore, 240 broiler chickens of ross 308 allocated to 24 experimental units in a completely randomized design with factorial 2x3 arrangements and four replicates of 10 birds. the experimental diets containing silymarin at 3 levels (0, 100, 200 mg/kg) and 2 le...
an experiment was conducted to study the effects of soybean, linseed and sunflower oil (various sources of fatty acids) with and without l-carnitine supplements (0 and 50 mg kg-1) on performance, blood biochemical parameters and carcass traits of japanese quail. one hundred and ninety-two of 7-day old female japanese quail were randomly assigned to 6 dietary treatments with 4 replicates and fed...
this study was conducted to evaluate the effect of camphor levels on performance, organ weight, testosterone and thyroid hormones, intestinal selective bacteria, and meat peroxidation of japanese quail. two-hundred 1-d chicks were allocated in 20 cages with five treatments and four replicates (10 chicks per each cage) using complete randomized block design. treatments were including: 0, 62.5, 1...
