3. Pre-slaughter factors associated with severe bruising in different primary commercial cuts of bovine carcasses
RESUMO A incidência de contusões nas carcaças bovinas é consequência de distintos fatores potencialmente estressantes e agressivos a que são submetidos os animais durante o manejo pré-abate. Este estudo teve como objetivo identificar os fatores pré-abate associados a lesões de contusões severas observadas em diferentes regiões da carcaça dos bovi

5. Body weight components of Nellore steers finished in tropical pastures
ABSTRACT. The aim of this study was to evaluate the effect of increasing levels of supplementation on body weight components of Nellore cattle grazing in Urochloa brizantha. Twenty-four steers with initial body weight (BW) of 371 ± 14 kg and average age of 26 months were used. Four animals were slaughtered at the beginning of the experiment as a reference a

6. Exogenous enzymes improve performance and carcass traits of feedlot cattle fed high-grain diet
ABSTRACT The objective of this study was to evaluate the effects of supplementation of two different enzymatic complexes, fibrolytic (NSPases) or amylolytic (EXP3066) enzymes, on growth performance, digestibility, behavior, and carcass characteristics of feedlot cattle. Thirty-six ½ Angus yearling bulls with an average initial weight of 391±5.0 kg were use

7. Feedlot performance, feeding behavior and rumen morphometrics of Nellore cattle submitted to different feeding frequencies
ABSTRACT: Owing to the lack of information in the literature about the ideal feeding frequency adopted by feedlot systems, this study was designed to evaluate the effect of different feeding frequencies on performance, carcass traits, feeding behavior and rumen morphometrics of Nellore cattle. Forty-eight yearling bulls were housed in individual pens with an

8. Dry matter intake, performance and carcass characteristics of hair sheep reared under different grazing systems
ABSTRACT The aim of this study was to evaluate the effect of three different grazing systems: isolated, alternate and simultaneous, on feed intake, performance and carcass characteristics of sheep. About 5.2 ha area of Tanzania grass (Panicum maximun Jacq cultivate Tanzania) was divided into 13 paddocks. This area was used as a stocking rate of two animal un

9. Proportions of sugarcane and babassu mesocarp bran in diets for feedlot cattle
ABSTRACT The objective of this study was to evaluate the production performance of feedlot cattle fed diets containing chopped sugarcane ratios (580 or 380 g/kg of diet dry matter) as roughage and levels of inclusion of babassu mesocarp bran (BMB; 420 to 620 g/kg of concentrate dry matter). Twenty-four young Nellore bulls with 321±23 kg initial body weight,

10. Carcass characteristics and meat evaluation of Nelore cattle subjected to different antioxidant treatments
ABSTRACT Forty Nelore cattle were used to evaluate the effects of supplementation with different antioxidants on carcass characteristics and meat quality of feedlot cattle. Animals were fed Brachiaria brizantha hay and subjected to five treatments (control and four antioxidants: zinc, selenium, vitamin E, and selenium + vitamin E). After a 105-day feeding pe

11. 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),

12. Phenotypic association between feed efficiency and feeding behavior, growth and carcass traits in Senepol cattle
ABSTRACT The objective of this study was to evaluate the associations between feed efficiency and feeding behavior, growth and carcass traits in Senepol cattle. A total of 137 animals were evaluated. Of these animals, 36 males were evaluated in a second test, totaling 173 records (initial age of 466±96 days and initial weight of 426±104 kg). Residual feed
