Dietary components and changes cause shifts in the gastrointestinal microbial ecology that can play a role animal health productivity. However, most information about populations gut of livestock species has not been quantitative. In present study, we utilized new molecular method, bacterial tag-encoded FLX amplicon pyrosequencing (bTEFAP) perform diversity analyses populations. cattle (n = 6) were fed basal feedlot diet subsequently randomly assigned to 1 3 diets 2 cows per diet). each...
The rumen microbial community in dairy cows plays a critical role efficient milk production. However, there is lack of data comparing the composition bacterial main breeds. This study utilizes 16S rRNA gene sequencing to describe Holstein and Jersey fed same diet by sampling microbiota via cannula (Holstein cows) or esophageal tubing (both cows). After collection sample tubing, particles attached strainer were added ensure representative both liquid solid fraction contents. Alpha diversity...
Feedlot producers could optimize the value of cattle in a given market grid if they were able to improve uniformity body composition between among loads. Allelic variation due single nucleotide transition (cytosine [C] thymine [T] that results Arg25Cys) has been demonstrated be associated with higher leptin mRNA levels adipose tissue and increased fat deposition mature beef, but effect on economically important carcass traits not investigated either market-ready steers or heifers. Therefore,...
Three experiments were conducted to evaluate nutrient content and DM determination methods of dry milling byproducts. In Exp. 1, composition was determined for wet distillers grains plus solubles (WDGS) modified (MDGS) from 6 ethanol plants with 10 samples collected per day, across 5 d, sampling repeated over 4 separate months. Mean 31.0% CP, 11.9% fat, 0.84% P, 0.77% S (DM basis). Coefficients variation greater some than others, occurred within days. Variability small CP whereas fat...
Increased corn prices over the past decade have altered land use away from traditional forage in favor of corn. Accordingly, beef and dairy producers had to adopt nontraditional resources into their production systems, many which become available as a result increased production. Corn residues more due increases hectares yield. The individual plant components (i.e., husk, leaf, stem) vary fiber digestibility (NDF estimates = 40.5, 31.4, 0.6% ± 0.8 for stalk, respectively). Stocking cattle...
Alga 1.0, a product containing bromoform, was fed to cattle evaluate its effects on methane (
SUMMARY The Cornell-Penn-Miner (CPM) Dairy is an applied mathematical nutrition model that computes dairy cattle requirements and the supply of energy nutrients based on characteristics animal, environment physicochemical composition feeds under diverse production scenarios. CPM was designed as a steady-state to use rates degradation feed carbohydrate protein rate passage estimate extent ruminal fermentation, microbial growth, intestinal digestibility fractions in computing post-rumen...
This work evaluated the National Research Council (NRC) dairy model (2001) predictions of rumen undegradable (RUP) and degradable (RDP) protein compared with measured postruminal non-ammonia, nonmicrobial (NANMN) microbial N flows. Models were using root mean squared prediction error (RMSPE) as a percent observed mean, slope biases percentages (MSPE), concordance correlation coefficient (CCC). The NRC over-estimated NANMN by 18% under-estimated 14%. Both responses had large (19% 20% MSPE,...
