25. SILAGEM DE PAPUÃ OU DE SORGO NA TERMINAÇÃO DE BOVINOS: TECIDOS CORPORAIS E CARACTERÍSTICAS DA CARCAÇA E DA CARNE / ALEXANDER GRASS SILAGE OR SORGHUM IN FINISHING CATTLE: BODY TISSUES AND CARCASS AND MEAT CHARACTERISTICS
O objetivo do presente estudo foi avaliar o efeito do uso da silagem de papuã (Urochloa plantaginea) sobre os tecidos corporais que não perfazem a carcaça, bem como, os aspectos quantitativos e qualitativos da carcaça e da carne de novilhos terminados em confinamento. Utilizaram-se 12 bovinos machos castrados, puros e mestiços Charolês x Nelore, com id

26. 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

27. Lipid and selenium sources on fatty acid composition of intramuscular fat and muscle selenium concentration of Nellore steers
The objective of this study was to evaluate the effect of lipid and selenium sources in diets for finishing Nellore steers on the fatty acid composition and selenium concentration of the longissimus muscle. Fifty Nellore steers (body weight = 458±39 kg) were assigned to one of six dietary treatments: 1) diet containing sunflower seed and inorganic selenium;

28. 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

29. Performance, carcass traits, meat quality and economic analysis of feedlot of young bulls fed oilseeds with and without supplementation of vitamin E
The objective of this research was to evaluate average daily gain (ADG), carcass traits, meat tenderness and profitability of keeping cattle fed different oilseeds and vitamin E in feedlot. A total of 40 Red Norte young bulls with initial average body weight of 339±15 kg were utilized. The experimental design was completely randomized in a 2 × 2 factorial

30. 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

31. Residual feed intake and its effect on carcass and meat characteristics of feedlot Zebu cattle
The objective of this study was to evaluate the residual feed intake (RFI) and its relation with performance, carcass and meat characteristics of Zebu animals. A total of 40 Zebu steers with initial age of 18 months and initial live weight of 350 kg were confined in feedlot for 112 days. The average daily gain (ADG) and dry matter intake (DMI) were obtained

32. Intake and performance of feedlot cattle fed diets based on high and low Brix sugar cane with or without calcium oxide and corn silage
The objective of this study was to evaluate low and high Brix diets, treated or not with 5 g of calcium oxide per kg of natural matter, and corn silage on intake, digestibility and performance of beef cattle. Forty cattle with initial body weight (BW) of 350 kg were used: five composed the control group, 30 were distributed into random blocks (control) and t

33. Reactivity, performance, color and tenderness of meat from Zebu cattle finished in feedlot
The objective of this study was to study the animal reactivity and correlate it with performance and meat quality of cattle finished in feedlots. A total of 20 animals of the Tabapuã breed and 20 animals of the Nellore breed were confined for 112 days: 28 days of adaptation and 84 days of data collection. Performance was determined by the average daily weig

34. Traceability of animal by product meals in broilers fed sugarcane yeast using stable isotopes
The objective of this study was to verify if the dietary inclusion of sugarcane yeast at levels commonly used in broiler diets influences the traceability of cattle meat meal and poultry offal meal, using the technique of stable carbon and nitrogen isotopes in the breast muscle of chickens. A number of 325 one-d-old male broilers were randomly distributed in

36. Corn silage with and without enzyme-bacteria inoculants on performance, carcass characteristics and meat quality in feedlot finished crossbred bulls
Two height cuttings of corn silage with or without enzyme inoculants were evaluated for 68 days on performance, carcass characteristics, meat quality and chemical composition of the Longissimus muscle in crossbred bulls (F1 - ½ Nellore vs. ½ Angus) finished in feedlot. Thirty-two 20-month-old bulls, with initial average weight of 374±25 kg, were kept in i
