13. Presence of central nervous system tissues as bovine spongiform encephalopathy specified risk material in Turkish raw meat ball (cig kofte)
Abstract Bovine Spongiform Encephalopathy (BSE) is a virulent disease which may infect by affecting the central nervous system (CNS) tissues in cattle and causes degeneration in nerves. Central nervous system tissues such as brain and spinal cord which are classified as specified risk materials (SRMs) are regarded to be main source of infection. The contamin

14. Body chemical composition, tissue deposition rates and gain composition of young Nellore cattle selected for postweaning weight
Empty body and carcass chemical composition were determined in 67 Nellore bulls from Selection Nellore (NeS) and Control Nellore (NeC) herds of an animal breeding program for growth, slaughtered at 570 days of average age, after 100 days of feedlot. Selection Nellore animals had, respectively, 360 and 430 kg of initial and slaughter body weight, and NeC anim

15. Reducing supplementation frequency for Nellore beef steers grazing tropical pastures
Reduced supplementation frequency is a broadly applied management practice. Ruminants consuming low quality forages/pastures, supplemented less than once daily are able to maintain body weight gain (BWG), efficiency of use of dry matter, nitrogen and other nutrients, as compared with animals supplemented once daily. We evaluated the feeding behavior, dry mat

16. 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

17. Crude glycerin in diets for feedlot Nellore cattle
Two studies were conducted to evaluate the effects of crude glycerin on feed intake, performance, carcass characteristics, and total digestibility of Nellore bulls. In experiment 1, cattle (n = 30) were fed a control diet without crude glycerin and diets containing 7.5, 15, 22.5, and 30% crude glycerin, for 103 d. Animals were harvested and data of carcass c

18. Carcass characteristics of feedlot-finished Zebu and Caracu cattle
This study analyzes the chemical carcass characteristics and carcass losses in 86 cattle, both castrated and non-castrated, with an average initial weight of 329 kg and an average age of approximately 20 months, including 12 Gyr, 20 Guzerat, 20 Nellore, and 20 Caracu among the herds selected for weight determination at 378 days of age, as well as 14 Nellore

19. Combined use of ionophore and virginiamycin for finishing Nellore steers fed high concentrate diets
Zebu cattle fed high concentrate diets may present inconsistent performance due to the occurrence of metabolic disorders, like acidosis. The isolated use of ionophores and virginiamycin in high grain diets can improve animal performance and reduce the incidence of such disorders, but recent studies suggested that their combination may have an additive effect

20. Feedlot performance, feed efficiency and carcass traits in Nellore cattle selected for postweaning weight
The objective of this study was to evaluate the correlated responses to selection for growth in feed efficiency and carcass traits of Nellore animals. A total of 121 animals of the Nellore control (NeC) and selection herds were subjected to performance testing and classified regarding residual feed intake (RFI). Sixty-seven of these animals were selected and

21. Performance, carcass characteristics and gain cost of feedlot cattle fed a high level of concentrate and different feed additives
The objective of this study was to evaluate the effects of feeding cattle with isoprotein and isoenergetic diets, with and without the addition of polyclonal antibody preparation (PAP), yeasts (YST) or monensin sodium (MON) on performance, carcass characteristics and gain cost in feedlot. Ninety-five 20-month old bullocks (323.3±21.8 kg) were distributed in

22. Copper and selenium supplementation in the diet of Brangus steers on the nutritional characteristics of meat
Twenty-eight Brangus cattle were used to determine the effect of copper and selenium supplementation on the carcass characteristics, fatty acid composition of the longissimus dorsi muscle and on the copper and selenium concentrations in the liver. The treatments were: no supplementation of copper or selenium; 2 mg Se/kg DM as sodium selenite; 40 mg Cu/kg DM

23. Seleção assistida por marcadores genéticos de características de carcaça em bovinos da raça Nelore / Genetic marker assisted selection of carcass traits in Nellore cattle
A pecuária de corte brasileira tem sofrido grande pressão devido às questões ambientais, às exigências dos mercados consumidores por carne de qualidade e rígidos padrões sanitários. Esses fatores aumentam a importância da melhoria da eficiência produtiva da pecuária de corte. A proposta do presente trabalho foi avaliar o efeito da inclusão dos v

24. Identificação e multiplicação de material genético com maior potencial para maciez de carne em bovinos da raça nelore mocho / Characterization and multiplication of genetic material with higher potential for meat tenderness in polled nellore cattle
O Brasil se apresenta como o maior exportador em volume de carne e não em valores financeiros, onde se destacam outros países, como EUA, Austrália e Argentina. Uma das características que depreciam a qualidade da carne bovina brasileira é a falta de maciez, isso porque a grande maioria dessa carne vem de animais com maior proporção genética zebuína,
