1. DIFFERENTIAL RESPONSE OF EPIPHYTIC LICHEN TAXA TO AGRICULTURAL LAND USE IN A FRAGMENTED FOREST IN CENTRAL ARGENTINA
ABSTRACT The seasonally dry subtropical forest, especially the Espinal forest in central Argentina (one of the most fragmented ecoregions), is affected by intensive agricultural activity. These activities are the main anthropogenic sources of atmospheric nitrogen compounds and their effects on lichens have been extensively studied, making them excellent ecol

2. Mycotoxin contamination of diets for beef cattle finishing in feedlot
ABSTRACT The objective of this survey was to identify what mycotoxins were present in ingredients used in diets offered to beef cattle in feedlots and their concentrations. The survey covered 30 Brazilian feedlots located in the five major beef-producing states. Samples of total mixed ration (TMR) and ingredients were collected and analyzed for mycotoxin usi

3. The economic viability of the inclusion of urea in the ration for feedlot lambs
RESUMO Objetivou-se com este estudo avaliar a viabilidade econômica da inclusão de ureia na ração fornecida para cordeiros terminados em confinamento. Foram utilizados 24 cordeiros machos não castrados, mestiços Dorper, com 2 a 5 meses de idade e 25,0 ± 4,3 kg de peso corporal (PC). O delineamento experimental foi inteiramente casualizado com quatro t

4. 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

5. Performance and fatty acid profile of Holstein calves slaughtered at different weights
ABSTRACT Our objective was to evaluate performance and fatty acid contents of the meat of Holstein veal fed in feedlots and slaughtered at four different pre-determined live weights (140, 180, 220, and 260 kg). Twenty-three non-castrated calves with initial average ages of 58 days and 57 kg live weight were used in this study. Average daily gain, dry matter

6. Challenges of beef cattle production from tropical pastures
ABSTRACT The live weight gain of cattle on tropical pastures is reviewed and found to be low and dependent on the length of the growing season. Supplements may be added to address the primary limiting nutrient, which, in the dry season, is crude protein. The response relationships of live weight gain to level of supplement (protein or energy) that have been

7. Associations among growth, scrotal circumference, and visual score of beef cattle in performance tests on pasture or in feedlots
ABSTRACT This study aimed to evaluate associations among final weight (FW), average daily gain (ADG), scrotal circumference (SC), and visual score (VS) of beef cattle in performance tests on pasture or in feedlots. Genetic parameters for FW, ADG, SC, and VS of young Nellore bulls performance-tested on pasture or in feedlots were evaluated by mixed model. The

8. Carcass and meat traits of feedlot Nellore bulls fed different dietary energy sources
ABSTRACT The objective of this experimental study was to evaluate the effects of different dietary energy sources on the carcass and meat traits of feedlot Nellore bulls. A total of 48 Nellore bulls at 32 months of age with 354.35±19.56 kg body weight were studied for 85 days. The bulls were allotted to four groups of 12 individuals: Whole corn grain - diet

9. Risk assessment of finishing beef cattle in feedlot: slaughter weights and correlation amongst input variables
The objective of this study was to evaluate the risk associated with finishing crossbred Charolais × Nellore steers in feedlot at different slaughter weights (425, 467 or 510 kg), considering or disregarding the correlation amongst random input variables. Data were collected from 2004 to 2010 and used in the simulation of the financial indicator Net Present

10. 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

ABSTRACT: The diet is one of the main costs animal production in feedlots. In addition, diet composition is one of the main determinants of the animal's performance. Therefore, adequate diet formulation is crucial for the success of the feedlot. This publication describes the fundamentals of diet formulation through the criteria of least cost of dry matter a
