| ABSTRACT This study aimed to compare some morphological and mechanical measurements of four different color female quails to contribute to the formation of the morphological database. Quails are the smallest farmed avian species which are becoming more important for the poultry industry. They are also used as experimental animals and are valuable birds for researches. Genetic factors are important determinants of bone strength. Thus, skeletal disorders may be reduced by breeding selection in quails. Forty female quails with four different feather colors, including wild, white, yellow, and black, were compared at 60 days of age. Each quail group contained ten individuals. A three-point bending test was performed with a custom-made testing machine designed... |

| The objective of this study was to assess the correlations of amylin (a pancreatic polypeptide hormone) with some hormonal, biochemical and bone parameters in pullets. Forty 18-week-old pullets were used. Plasma amylin, CT (calcitonin), 1,25 (OH)2 vitamin D (1,25 dihydroxycholecalciferol ), serum osteocalcin, glucose, ALP (alkaline phosphatase), cholesterol, and triglycerides, as well as weight, length and total volume of tibiotarsi were measured. Plasma amylin concentration was negatively correlated with serum cholesterol (p<0.05) and triglycerides (p<0.05) concentrations. Plasma amylin concentration was significantly and positively correlated with plasma calcitonin concentrations (p<0.001). Serum ALP and plasma amylin concentrations were... |

| The objective of this study was to evaluate the chemical composition and bone strength of the tibiotarsus of broilers at 7 and 14 days of age. Bone percentages of collagenous protein (CPr), non-collagenous protein (NCPr) and minerals (calcium, phosphorus, potassium and sodium) were determined. The experiment utilized 650 male Cobb chicks at one day of age, fed corn and soybean meal-based diets. The experimental design was of random blocks with five treatments, five replicates and 26 birds per experimental unit. The treatments consisted of a basal diet supplementated with NH4Cl to obtain five levels (-50, 0, 50, 100 and 150 mEq/kg) of electrolyte balance (EB). The levels of EB influenced the following characteristics: ash and potassium content; Ca:P ratio... |
