1. Oxidative stability, fatty acid composition and health lipid indices of Longissimus dorsi muscle from Aberdeen Angus steers produced in different feeding systems
RESUMO: O objetivo deste estudo foi avaliar o estado oxidativo e antioxidante do músculo Longissimus dorsi (LD), sem maturação e amadurecido, obtido de um matadouro comercial. Também foram comparados a composição de ácidos graxos e os índices lipídicos de saúde da carne calculados. Os animais abatidos foram os novilhos Aberdeen Angus criados em tr

2. Meat quality of Maremmana young bulls
ABSTRACT. Maremmana is a local Italian breed reared in southern Tuscany and northern Latium. Twenty-two young bulls were reared in pasture system with concentrate supply (PSCS), whereas 20 young bulls were reared in feedlot intensive system (IS) in order test differences between meat typologies. The bulls were slaughtered at 18 months old. The performances a

3. The use of guava byproduct in the production of feedlot sheep in Brazil: impacts on the productive and economic performance
ABSTRACT This study evaluated the effects of replacing ground corn with dehydrated guava (Psidium guajava L.) byproduct, at concentrations of 0.0, 8.2, 16.4, and 24.6% on the intake and digestibility of nutrients as well as on productive and economic performance of lambs. The study included 40 uncastrated feedlot Santa Inês sheep with an average age of 120

4. Influence of lamb finishing system on animal performance and meat quality
ABSTRACT. This study aimed to assess the influence of lamb finishing systems on zootechnical performance, as well as on carcass and meat quality. The experiment was conducted at the APTA’s experimental farm. Thirty-three lambs were used - both sexes, initial age of 90 ± 3 days, Texel with Santa Inês, each animal being one experimental unit, with 6 males

5. TERMINAÇÃO DE CORDEIROS, COM E SEM SUPLEMENTAÇÃO NA FASE DE CRIA, CONFINADOS OU SEMICONFINADOS EM Brachiaria brizantha DIFERIDA: PARASITISMO GASTRINTESTINAL E EFICIÊNCIA BIOECONÔMICA
Resumo Objetivou-se avaliar os efeitos da suplementação na fase de aleitamento sobre o desempenho ponderal, o grau de infecção por nematódeos gastrintestinais e a viabilidade econômica na terminação de cordeiros em confinamento ou semiconfinamento. Na fase de aleitamento, os cordeiros de seis lotes de 30 ovelhas foram pesados ao nascimento e ao desma

6. Roughage-free finishing diet based on whole corn grain and a mixture of additives for Nellore heifers
ABSTRACT This study was carried out to evaluate the effect of a blend of additives (choline, methionine, selenium, and organic zinc) on performance, feed efficiency, rumen parameters, and carcass traits of Nellore heifers finished with roughage-free diet. Nellore heifers (n = 36; average BW = 244±24.1 kg; average 24 months of age) were maintained in a feedl

7. Stabilization of confined beef cattle manure: characteristics of produced fertilizers
ABSTRACT The growing demand for animal protein is directly related to the feedlot system of animals and their assumptions, such as the waste management. The characterization of the final products becomes an important factor in decision making by one or by other process. The objective was highlight characteristics that fertilizers present due to the used of s

8. Dorper sheep utilizing feed resources efficiently: a Mediterranean case study
ABSTRACT The aim of the study was to determine the effect varying feeding systems would have on meat quality and production. The study looked at 45 Dorper lambs which were subjected to three different feeding protocols representing three alternate production systems: extensive grazing system (Group G), an intensive feedlot system being fed concentrate + alfa

9. Complementarity in the adoption of traceability of beef cattle in Brazil
Abstract Complementarity is an interesting approach to explain technology adoption. Taking account the other activities the farm performs in its production strategy can help understanding the decision on the adoption of new agricultural technology. This paper aims to evidence the existence of synergic effect resulting from the joint adoption of feedlot and t

10. Physicochemical characteristics and fatty acid profile of meat from lambs with different genotypes and diets
The objective of this study was to evaluate the chemical composition and fatty acid profile of meat from Santa Inês, Dorper × Santa Inês, and undefined-breed lambs finished in a feedlot system according to two forage:concentrate ratios (50:50 and 20:80) in the diet. Overall, 54 non-castrated animals were used (with an average initial weight of 23±1.5 kg

11. Performance and carcass quality of feedlot- or pasture-finished Nellore heifers according to feeding managements in the postweaning phase
The objective of this study was to evaluate the postweaning history of heifers kept on marandu grass pastures with three canopy heights, in a continuous-grazing system, during the rainy period, on feedlot- or pasture finishing. The effects of three canopy heights (15, 25 and 35 cm) associated with two supplements (mineral salt and protein-energy supplement)

12. Common factors method to predict the carcass composition tissue in kid goats
The objective of this work was to analyze the interrelations among weights and carcass measures of the longissimus lumborum muscle thickness and area, and of sternum tissue thickness, measured directly on carcass and by ultrasound scan. Measures were taken on live animals and after slaughter to develop models of multiple linear regression, to estimate the co
