13. Sunki mandarin and Swingle citrumelo as rootstocks for rain-fed cultivation of late-season sweet orange selections in northern São Paulo state, Brazil
ABSTRACT In Brazilian regions affected by the citrus sudden death disease, sweet orange cultivation depends on the use of resistant rootstocks. Rangpur lime was mainly replaced by Swingle citrumelo and Sunki mandarin rootstocks, more drought-sensitive ones. The diversification of scion selections is also desirable aiming at the increasing demand for not from

14. Genetic parameters of age at first calving, weight gain, and visual scores in Nelore heifers
ABSTRACT This study aimed at estimating the heritability of age at first calving and of performance traits included in the selection index and the genetic correlations between age at first calving and these performance traits. Data were extracted from the Conexão Delta G database and only data from herds in which heifers were bred younger than 24 months of

15. Central precocious puberty: revisiting the diagnosis and therapeutic management
ABSTRACT Clinical and laboratory diagnosis and treatment of central precocious puberty (CPP) remain challenging due to lack of standardization. The aim of this revision was to address the diagnostic and therapeutic features of CPP in Brazil based on relevant international literature and availability of the existing therapies in the country. The diagnosis of

16. Precocidade sexual em bovinos Nelore avaliada por ultrassonografia testicular
The present study aimed to evaluate if there are differences in testicular parenchyma echogenicity between pre-pubescent and pubescent animals at the same age. Ultrasound examinations were performed in longitudinal and transversal planes of the testicles of 111 healthy Nelore bovines, at the ages of nine, 13 and 15 months. The EIV software calculated the ech

17. Correlations of visual scores, carcass traits, feed efficiency and retail product yield in Nellore cattle
The growing use of visual scores (VS) and ultrasound (US) for carcass evaluation in breeding programs, calls for a knowledge of the relationships between these traits and other relevant characteristics, such as feed efficiency and production of commercial cuts. The objective of this study was to evaluate correlations between body visual scores and carcass tr

18. Estimates of genetic parameters for visual scores and their correlation with production and reproductive traits in Brahman cattle
The objective of this study was to evaluate the association of visual scores of body structure, precocity and muscularity with production (body weight at 18 months and average daily gain) and reproductive (scrotal circumference) traits in Brahman cattle in order to determine the possible use of these scores as selection criteria to improve carcass quality.

19. Análise metabolômica via RMN: amostras de urina e látex / Metabolomic analyses by NMR: urine and latex samples
The aim of the first part of this work was to apply the concept of metabolomic analyses in urine samples obtained from humans diagnosed with type 2 diabetes mellitus (T2DM) and impaired glucose tolerance (IGT) and treated with yerba-mate (Ilex paraguariensis) infusions using nuclear magnetic resonance. T2DM is the most recurrent type of diabetes and correspo
