Buriti oil as an alternative to the use of antimicrobials in broiler diets.

The objective of this study was to evaluate the effects and economic viability of diets containing different levels of antibiotic and buriti oil (BO) on performance, carcass and cut yields, and relative weight of organs of broilers. A total of 432 one- to 42-day-old male chicks were distributed in a completely randomized experimental design with six treatments, each consisting of six replicates of 12 birds. The treatments consisted of one diet with antibiotic without BO, one diet without antibiotic (DWA) without BO, and four DWA containing increasing levels of BO (0.

Chemical composition and nutrient digestibility of insect meal for broiler.

To determine the chemical composition and digestibility of insect meal for poultry made from the larvae of Tenebrio molitor (TL) and nymphs of Gryllus assimilis (GAN) a total excreta collection test was carried out, substituting 20% of the reference diet with each type of meal. The meals presented 6074 and 5975 kcal/Kg of gross energy, with 49.34% and 52.

Prevalence of noise-induced hearing loss in drivers.

Introduction:  Work-related hearing loss is one of the most common occupational illness progresses over the years of noise exposure associated with the work environment, may cause damage to undertake physical activity, the individual's physiological and mental besides causing hearing damage irreversible interfering with communication and quality of life. With high prevalence of male evaluates which is the second leading cause of hearing loss. Since there is no medical treatment for this type of hearing loss, it is evident the importance of preventive and conferences aimed at preserving hearing and health as a whole.

Influence of dental metallic artifact from multislice CT in the assessment of simulated mandibular lesions.

Objective: This study evaluated the influence of metallic dental artifacts on the accuracy of simulated mandibular lesion detection by using multislice technology.

Material And Methods: Fifteen macerated mandibles were used. Perforations were done simulating bone lesions and the mandibles were subjected to axial 16 rows multislice CT images using 0.

Assessment of linear and angular measurements on three-dimensional cone-beam computed tomographic images.

Objective: The purpose of this research was to provide further evidence to demonstrate the precision and accuracy of maxillofacial linear and angular measurements obtained by cone-beam computed tomography (CBCT) images.

Study Design: The study population consisted of 15 dry human skulls that were submitted to CBCT, and 3-dimensional (3D) images were generated. Linear and angular measurements based on conventional craniometric anatomical landmarks, and were identified in 3D-CBCT images by 2 radiologists twice each independently.

3-D volume rendering maxillofacial analysis of angular measurements by multislice CT.

Objective: This study was designed to determine the precision and accuracy of angular measurements using three-dimensional computed tomography (3D-CT) volume rendering by computer systems.

Study Design: The study population consisted of 28 dried skulls that were scanned with a 64-row multislice CT, and 3D-CT images were generated. Angular measurements, (n = 6) based upon conventional craniometric anatomical landmarks (n = 9), were identified independently in 3D-CT images by 2 radiologists, twice each, and were then performed by 3D-CT imaging.
