The effect of feed restriction and enzymatic supplementation on intestinal and pancreatic enzyme activities and weight gain was studied in broiler chickens. Quantitative feed restriction was applied to chickens from 7 to 14 d of age. An enzyme complex mainly consisting of protease and amylase was added to the chicken ration from hatching to the end of the(More)
The 13C turnover rates of the liver and thoracic pectoral muscle of growing broilers were determined by feeding diets with varying 13C content. Male chicks (1-d-old) were subjected to treatments based on free choice of 5 different mixes of energy and protein sources from plants with C3 and C4 photosynthetic pathways that had differing 13C content. Rice bran(More)
The present study aimed to quantify the proportion of 13C from energy and protein feed ingredients that follow the metabolic routing of the liver and muscle in broiler chickens. A stable isotope of carbon technique was used that is based on the isotopic discrimination that occurs in the plants during the photosynthesis process. One-day-old male chicks were(More)
BACKGROUND The high and increasing prevalence of Dilated Cardiomyopathy (DCM) represents a serious public health problem. New technologies are being used aiming at more accurate diagnoses in order to improve therapeutic approach. In this scenario, speckle tracking echocardiography (STE) uses natural myocardial markers to analyze the systolic deformation of(More)
BACKGROUND A coil in the internal carotid artery (ICA), defined as a circular configuration or exaggerated S shape of the ICA, is occasionally encountered during endarterectomy for carotid bifurcation lesions. The significance of coils as an etiology for symptoms is difficult to determine. It is thought, however, that the failure to correct coils and kinks(More)
Studies on the detection of animal by-products in poultry meat are rare and practically nonexistent in chicken meat. With the development of the technique of stable isotopes for traceability purposes and the certification of broiler diet patterns, it has been necessary to know the behavior of the isotopic signature of different tissues in birds, in case of(More)
