1. 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

2. Performance and carcass characteristics of lambs fed a solution of crude glycerin during feedlot and pre-slaughter lairage
ABSTRACT The objective of this study was to evaluate performance and carcass and meat characteristics of lambs fed a solution of crude glycerin plus water (100 g kg−1 of dry matter) (GLY) during feedlot and pre-slaughter lairage. Data were analyzed as a 2 × 2 factorial (GLY available or not in feedlot and GLY available or not in the slaughterhouse). We ev

3. Performance and carcass characteristics of lambs fed a solution of cheese whey during feedlot and pre-slaughter lairage
ABSTRACT The objective of this study was to evaluate performance and carcass and meat characteristics of lambs fed a solution of cheese whey plus water (100 g kg−1 dry matter) (CW) during feedlot and pre-slaughter lairage. Data were analyzed as a 2 × 2 factorial (place – feedlot and slaughterhouse, food – water or CW). We evaluated the following treat

4. Caracterização da curva de crescimento de fêmeas Crioulas Lageanas criadas em condições naturais
Morphometry and ultrasound of carcasses were used to estimate the growth curve of Criola Lageana cows, raised under natural conditions. A total of 111 cows, raised under extensively production system in Central Plateau of Santa Catarina, were evaluated. Morphometrics and ultrasound measurements were related with the age of the animals using the targeted univ

5. 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

6. Performance, carcass and meat quality of ewes supplemented with magnesium oxide
The objective of this study was to evaluate the performance, the carcass and meat characteristics of ewes supplemented with magnesium oxide. Eighteen 6-year-old Santa Ines ewes were used in a completely randomized experimental design, where three levels of supplementation (0.0, 0.1 and 0.2% magnesium oxide in the concentrate) were tested, with six replicates

7. Growth curve of locally adapted pantaneiro cows raised under natural conditions
The objective of this study was to use morphometric and ultrasound evaluations to estimate the growth curve of the Pantaneiro cattle breed, raised in its natural habitat, aiming at the re-insertion of this breed in production systems. One hundred and three females, aging from months to 11 years, and raised on native pastures, were evaluated. The animals belo

8. 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

9. 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

10. Measurement of rib-eye area by the method of digital images
This study evaluated the correlation between measurements of rib-eye areas of sheep carcasses by traditional methods and those obtained by scanned images. Thirty pictures of the longissimus dorsi muscle of sheep carcasses were drawn on tracing paper and analyzed for muscle area (rib-eye) using four methods: scanned images, which utilizes the software DDA -De

12. Performance, carcass characteristics and meat quality of beef cattle for efficiency stratified by residual feed intake / Desempenho, características de carcaça e qualidade de carne de bovinos Nelore estratificados pela eficiência através do consumo alimentar residual
The supply of food is the highest cost input in livestock enterprises. Selection for feed efficiency in beef cattle was mostly ignored by the difficulty and cost of measuring individual consumption, besides the fact that efficiency is correlated with gain rate. An alternative index for measuring feed efficiency, not associated with increased adult size, woul
