13. QUALIDADE DA CARCAÇA E CARNE DE NOVILHOS ALIMENTADOS COM DIETAS COM BORRA DE SOJA / CARCASS AND MEAT QUALITY OF STEERS FED DIETS WITH SOYBEAN SOAPSTOCK
The objective of this study was to evaluate carcass characteristics, the non carcass components, the lipid profile and the sensorial characteristics of meat from steers finished in feedlot fed diets containing different levels of inclusion of soybean soapstock. We used 30 Nellore and Charolais-Nellore crossbred steers with initial mean age of 20 months and i

14. FONTES DE CARBOIDRATOS PARA TERMINAÇÃO DE BOVINOS DE CORTE: DESEMPENHO E CARACTERÍSTICAS DA CARCAÇA E DA CARNE / SOURCES OF CARBOHYDRATES FOR STEERS FINISHING: PERFORMANCE AND CARCASS CHARACTERISTICS AND MEAT
The objective of this study was to evaluate the effect of three carbohydrate sources (corn, soybean hulls or wheat bran) in the diet on performance, carcass characteristics and meat and the components are not part of the carcass of steers finished on confinement. We used 24 steers, crossbred Charolais x Nellore, with initial age of 22 months of initial body

15. Development and reproductive performance of beef heifers supplemented with brown rice meal and/or protected fat on temperate grasslands
The response of energy supplementation was evaluated on the development and reproductive performance of beef heifers on temperate grasslands. Twenty-eight Charolais × Nellore heifers, with initial average age of 18 months and initial live weight of 274.9 kg were utilized. The animals were maintained on oat + ryegrass pasture and distributed in the following

16. Behavior pattern of beef heifers supplemented with different energy sources on oat and ryegrass pasture
The objective of this study was to evaluate behavior patterns of heifers grazing on black oat (Avena strigosa Schreb.) and ryegrass (Lolium multiflorum Lam.), fed supplementation with brown rice meal and/or protected fat. A total of 28 Charolais × Nellore crossbred heifers at average initial age of 18 months and with initial live weight of 274.9±4.97 kg we

17. Production parameters and forage loss of oat and rye grass pastures managed with beef heifers fed diets with energy supplementation
Production parameters of intercropped pastures of oat and rye grass managed with beef heifers supplemented with brown rice meal and/or protected fat were evaluated. Twenty-eight Charolais × Nellore crossbred heifers at initial average age of 18 months and initial average live weight of 274.9 kg were utilized in the experiment. Animals were kept on oat + rye

18. Relationship between temperament with performance and meat quality of feedlot steers with predominantly Charolais or Nellore breed
The relation between temperament with performance and meat quality was determined in 79 Charolais × Nellore steers kept in feedlot. Temperament was evaluated according to exit velocity, scale composite score and flight distance four times in the finishing phase, along with body weight, intake and feed conversion measures. Cattle were classified as calm, int

19. Heteroskedasticity for weaning weight of Charolais-Zebu crossbred calves
The objective of the present study was to analyze models with genetic and/or residual heteroskedasticity for genetic evaluation of the weaning weight of Charolais-Zebu crossbred calves. Weaning weight data from 56,965 crossbred calves were analyzed using animal models with different combinations of genetic and residual heteroskedasticity and/or homoskedastic

20. Carcass characteristics, chemical composition and fatty acid profile of longissimus muscle of young bulls from four genetic groups finished in feedlot
This experiment was carried out to evaluate the carcass characteristics, chemical composition and fatty acid profile of the longissimus muscle of 32 young bulls from four genetic groups: Caracu; Canchin; Aberdeen Angus × Canchin; and Charolais × Caracu, finished in feedlot and slaughtered at 22 months old. Each group was composed of eight animals. There wa

21. Association of CSSM066 and ILSTS011 microsatellite markers and thyroglobulin gene SNP with backfat in Canchim cattle
Canchim, a synthetic breed of cattle derived from the Charolais and Zebu group has been used in the beef-cattle industry in Brazil as an alternative for intensifying production. One of the main concerns with this breed is its poor fat deposition and consequently, there is an effort to increase the performance for this trait. The thyroglobulin gene is located

22. Genetic diversity of tyrosine hydroxylase (TH) and dopamine b-hydroxylase (DBH) genes in cattle breeds
DNA from four cattle breeds was used to re-sequence all of the exons and 56% of the introns of the bovine tyrosine hydroxylase (TH) gene and 97% and 13% of the bovine dopamine b-hydroxylase (DBH) coding and non-coding sequences, respectively. Two novel single nucleotide polymorphisms (SNPs) and a microsatellite motif were found in the TH sequences. The DBH s

23. Behavior patterns of cows with Charolais or Nellore breed predominance fed diets with plant extract or monensin sodium
The objective of this research was to study the ingestive behavior of feedlot cows fed additives based on plant extracts or monensin sodium. Twenty-four Charolais and Nellore crossbred cows with age and average initial weight of 7 years and 423 kg, respectively, were used. The experimental diets were plant extracts: basal diet + 5 g/animal/day of a natural a

24. Carcass physical composition and meat quality of Charolais cattle of different categories
The objective of the experiment was to study the carcass physical composition and meat qualitative characteristics of different categories of Charolais cattle, feedlot finished. Nine steers (ST), ten heifers (HE), with average age of 20 months, and ten cull cows (CO) with average age of 87 months, taken from the same herd, were used. Diet contained 13% of cr
