In the present project, four studies will be proposed. The objective of the Study 1 will be to evaluate the effect of genetics and physically effective neutral detergent fiber (peNDF). Six ruminal cannulated cattle, three Angus and three Nellore will be conducted as a 3×3 Latin square with 2×3 factorial arrangement of treatments. Factors will include genetics (Angus vs. Nellore) and peNDF…
Roughage should be included at reduced levels in high-concentrate diets due to lower nutritional composition, higher operating costs and to maximize energy intake during the feedlot period. Therefore, optimizing roughage levels in high-concentrate diets is necessary to improve animal performance. Thus, this study aimed to test the effect of physically effective neutral detergent fiber (pe…
The objective of this study will be to evaluate the effect of different roughage and physically effective neutral detergent fiber (peNDF) inclusion on ruminal pool sizes and neutral detergent fiber (NDF) turnover rate in feedlot Nellore cattle. Eight cannulated Nellore yearling steers (450 kg), will be housed in individual pens (21 m2). The study will be conducted as 4 × 4 Latin squares …
The objective of this study will be to evaluate the effect of roughage and physically effective neutral detergent fiber (peNDF) inclusion in finishing diets fed to feedlot cattle on ruminal fermentation and motility, bacterial community composition, eating behavior, and total tract digestibility. Eight cannulated Nellore yearling steers (450 kg), will be housed in individual pens (21 m2).…

Insufficient fiber may increase the risk of nutritional disorders such as ruminal acidosis, negatively impacting health, and consequently growth performance of feedlot cattle. Forages are included at minimal levels when formulating finishing cattle diets due to lower digestibility and higher operational and economic costs than concentrates. The objective of this study will be to evaluate …
The lower fiber inclusion in finishing diets may increase the risk of nutritional disorders such as ruminal acidosis, negatively impacting health, and consequently growth performance of feedlot cattle. Thus, this study aimed to test the effect of starch and physically effective neutral detergent fiber (peNDF) inclusion on dry matter intake (DMI) variation and ruminal motility of feedlot c…

This study will investigate the effects of replacing dried distillers grains (DDGS) with soybean meal on energy metabolism, nutrient flow and digestibility, and methane emissions in beef cattle. Four rumen-, duodenum-, and ileum-cannulated Red Angus steers will be assigned to a 4×4 Latin square design. The experimental diets will include: 1) A control diet with DDGS (15% DM); 2) A diet re…
Variability in the ability of cattle to digest feed has been considered one of the main factors affecting feed efficiency. Previous work to understand this variability have used residual feed intake (RFI), a measure in the divergence in feed intake from a predicted intake model based on rate of gain and body size to identify cattle with divergent feed efficiency. This project proposes an …
This study is designed to determine the effects of supplemental methionine and zinc on feedlot performance, carcass characteristics, muscle satellite cells, protein extraction and rumen morphometrics of cattle fed high-grain diets. The trial will be conducted at Texas Tech University, Lubbock, USA. One hundred forty-four British-crossbred steers (Initial body weight = 360 kg) will be hous…
