1. Energia metabolizável e aminoácidos digestíveis de coprodutos de trigo e de farinhas de origem animal em dietas para frangos de corte
ABSTRACT The objective of this study was to determine the metabolizable energy, standardized ileal amino acid digestibility (SIAAD) and digestible amino acid values of wheat meal (WM), wheat gluten meal (WGM), meat bone meal (MBM) and poultry-by-product meal (PPM) in diets for broilers. In the first experiment, the total excreta collection method was used, w

2. Influence of Artemisia Annua on Broiler Performance and Intestinal Microflora
ABSTRACT The present study aimed to investigate the effect of Artemisia (Artemisia annua) supplementation as essential oil and powder, in broiler diet on performance and intestinal microflora. One hundred and eighty Cobb 500 broiler chicks assigned to three experimental groups (six replicates with 10 broilers per replicate) were housed in an environment-cont

3. Performance Parameters, Plasma Lipid Status, and Lymphoid Tissue Fatty Acid Profile of Broiler Chicks Fed Camelina Cake
ABSTRACT The effects of dietary camelina cake (CAMC) on broiler chicks’growth performance, plasma lipid status and fatty acid profile (FA) of lymphoid organs were evaluated. Six hundred broilers (3-week-old, Cobb 500) were randomly allotted for 20 days in a feeding trials into 2 groups: control (C; corn-soybean meal-canola meal basal diet) and experimental

4. Assessment of 47Ca Distribution and Biological Half-Life in Japanese Quail Chicks
ABSTRACT A study was conducted to assess 47Calcium (47Ca) distribution and biological half-life in different body organs of Japanese quail chicks. A total of 85, 4 week old chicks, were dosed with 1ml/chick volume of 1% (w/v) CaCl2 solution containing 7.51x10-08 Ci 47Ca which is equivalent to 1.27x10-13 g. 47Ca activity, in terms of decay per minute (DPM), w

5. Effects of Varying Essential Oil Mixture Concentrations Applied Underconditions of Different Temperature Stress on Cardiac Markers and Other Blood Parameters
ABSTRACT Cardiac troponin (cTnI) and erythrocyte distribution width (RDW) have been used as specific markers for the evaluation of cardiac arrhythmias and myocardial diseases. In this experimental study, we aimed to determine the dose-dependent administration of an Essential OilMixture (EOM) (Eucalyptus globulusLabill, Thymus vulgaris, Cymbopogon nardus, and

7. Effect of Exogenous Protease, Mannanase, and Xylanase Supplementation in Corn and High Protein Corn DDGS Based Diets on Growth Performance, Intestinal Morphology and Nutrient Digestibility in Broiler Chickens
ABSTRACT A study was conducted to evaluate the effects of exogenous enzymes supplementation in high protein (Hi-Pro) corn DDGS-based diets on broiler growth performance, intestinal health, and nutrient digestibility. A total of 200 one-day-old broiler chicks were randomly allocated to four dietary treatments with five replicates of 10 birds each. A basal die

8. Morphological Investigations of the Effect of Thermal Manipulation During Embryogenesis on Body Performance and Structure of Pectoral and Thigh Muscle of Ross Broiler Chicken
ABSTRACT The aim of this study was to determine the optimum timing of thermal manipulation during early, mid, late and long lasting embryogenesis that may result in improvement of body performance and myofiber development (fiber diameter and thickness of perimysium) of pectoral and thigh muscles by a comparative morphometrical investigation on post-hatch day
