2. DESEMPENHO, CARACTERÍSTICAS DE CARCAÇA E DA CARNE DE NOVILHAS DA SEXTA GERAÇÃO DO CRUZAMENTO CHAROLÊS X NELORE ABATIDAS AOS 18 MESES DE IDADE
Resumo O objetivo do presente estudo foi avaliar o desempenho, as características quantitativas da carcaça e qualitativas da carne de novilhas de sexta geração oriundas do cruzamento entre as raças Charolês e Nelore abatidas aos 18 meses de idade. Os tratamentos testados foram os grupos genéticos 43/64 Nelore 21/64 Charolês (4364NE) e 43/64 Charolês

3. Delayed carcass chilling improves tenderness of the beef gluteus medius muscle
Resumo: O objetivo deste trabalho foi avaliar os efeitos de uma taxa de resfriamento mais lenta sobre as características físico-químicas da alcatra (M. gluteus medius) de touros F1 Angus x Nelore, maturada por 14 dias. Carcaças leves e magras (n = 30) foram divididas em meias carcaças e selecionadas para controle (2°C por 24 horas) e tratamento (10°C

4. BREED AND CARCASS CHARACTERISTICS ON LOSSES BY BRUISES AND MEAT PH IN BEEF OF STEERS AND CULLING COWS
Resumo Objetivou-se avaliar os efeitos de grupo genético, maturidade e escore de gordura de acabamento de bovinos sobre perdas por contusões e valor do pH final da carcaça de bovinos machos e fêmeas. O número de contusões e o valor final do pH das carcaças foram avaliados como variável resposta em função do grupo genético, da maturidade fisiológi

5. Development and evaluation of models to estimate body chemical composition of young Nellore bulls
ABSTRACT The objective of this study was to develop accurate regression equations to predict body composition of Nellore cattle using chemical composition of the 9th, 10th, and 11th ribs and to evaluate the models proposed by analyzing mean and linear bias. Sixty-seven Nellore bulls were slaughtered and slaughter body weight (SBW), hot carcass weight (HCW),

6. 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

7. 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

8. Acetic acid as an intervention strategy to decontaminate beef carcasses in mexican commercial slaughterhouse
Beef can be contaminated during the slaughter process, thus other methods, besides the traditional water washing, must be adopted to preserve meat safety. The objective of this study was to evaluate the effect of 2% acetic acid interventions on the reduction of indicator bacteria on beef carcasses at a commercial slaughterhouse in Mexico. Reduction was measu

9. Animal performance and carcass characteristics of Nellore young bulls fed coated or uncoated urea slaughtered at different weights
The objective of this study was to evaluate animal performance and carcass characteristics of 64 Nellore young bulls at 22 months of age finished in a feedlot and slaughtered at five body weights (350; 455; 485; 555 and 580 kg) fed diets containing coated or uncoated urea. The experimental design adopted was completely randomized, set in a 4 × 2 factorial a

10. Inclusão de grão de milheto em dietas de alto concentrado para ovinos em confinamento / Inclusion of a grain of corn in diets high concentrate for sheep in confinement
The ovine production is an activity that has developed gradually in the country, and growing in areas where before the sheep industry was negligible, enabling livestock production systems in small, medium and large farms and becoming a more profitable alternative investment means in agriculture, when compared with other agricultural as for example, beef catt

11. Relações entre eficiência alimentar, características de carcaça e qualidade de carne de novilhos Nelore confinados / Feed efficiency and its relationships with profitability, carcass characteristics and meat quality of Nellore steers
Although Brazil has the largest commercial beef cattle herd of the world, research on genetic improvement of beef cattle for feed efficiency is incipient. Some countries have invested in studies to identify feed efficient animals and to find molecular markers associated with this characteristic. Genetic selection of efficient animals can resulting lower cost

12. Association of polymorphisms in the leptin and thyroglobulin genes with meat quality and carcass traits in beef cattle
The objective of the present study was to estimate the allelic and genotypic frequencies of the polymorphisms E2FB (AY138588.1: c.305C> T), located in the leptin gene (LEP), and TG5 (X05380.1:g.-422C>T), located in the thyroglobulin gene (TG), and evaluate the association of these polymorphisms in crossbred cattle of seven distinct genetic groups with the fo
