The objective of this study was to evaluate the in situ degradation profiles of dry matter (DM) and neutral detergent fiber (NDF) of different forages using nylon (50 µm), F57 (Ankom®) and non-woven textile (NWT - 100 g/m2) bags. Eight forage samples were used: sugarcane, corn silage, elephant grass cut at 50 and 250 days of regrowth, corn straw, signal grass hay, coast cross hay, and fresh alfalfa. Samples were incubated for 0, 3, 6, 12, 18, 24, 48, 72, 96, 120, 144, 168, 192, 216, 240, and… Expand

Review: Recent advances in evaluation of bags made from different textiles used in situ ruminal degradation
TLDR
The effects of particle size, the material from which bags are made, pore size, tensile strength of the bags, in situ estimation of the levels of indigestible compounds, and the rumen degradation profiles are reviewed. Expand
Supplementation with different protein profiles for grazing beef cattle supplemented in tropical grass during the rainy-dry transition season.
TLDR
Evaluating increasing levels of inclusion of dry distillery grains (DDGs) in substitution of corn and urea in multiple supplements for beef cattle of Urochloa brizantha cv. Expand
Crude glycerin as an alternative to corn as a supplement for beef cattle grazing in pasture during the dry season
TLDR
CG in the supplement of Nellore steers grazing tropical grass during dry season doesn’t affect intake and digestibility but alters ruminal fermentation, without negative effect on relative proportion of cellulolytic bacteria population. Expand
Interaction between tannin and urea on nitrogen utilization by beef cattle grazing during the dry season
Abstract Tannins are secondary plant products that may reduce ammonia in the rumen and increase amino acid flow to intestine, but a reduction in ruminal N availability can limits its use for beefExpand
Effects of ruminal and post-ruminal protein supplementation in cattle fed tropical forages on insoluble fiber degradation, activity of fibrolytic enzymes, and the ruminal microbial community profile
TLDR
In disagreement with data of degradation and digestibility, decreases in enzymatic activity were observed mainly for post-ruminal supplementation, but the improvement in forage quality increased, and the in vitro degradation rate of neutral detergent fiber increased. Expand
NUMBER OF COWS AND BAGS NEEDED TO ESTIMATE in situ DRY MATTER DEGRADATION OF KINGGRASS (Pennisetum purpureum) LEAVES
TLDR
The number of bags to be incubated per sample, and the number of fistulated cows needed to estimate in situ ruminal degradation of Kinggrass dry matter (DMD %) were determined. Expand
Effects of rumen undegradable protein on intake, digestibility and rumen kinetics and fermentation characteristics of dairy heifers
Abstract The aim of this work was to evaluate the influence of increasing amounts of rumen undegradable protein (RUP) on intake, nutrient digestibility, rumen kinetics and fermentationExpand
Effects of maturity at harvest on the nutritive value and ruminal digestion of Eragrostis tef (cv. Moxie) when fed to beef cattle.
TLDR
Despite a decrease in CP intake and ruminal NH3-N concentration, feeding beef heifers EH and LH compared to BT teff hay did not compromise ruminal digestion and outflow of DM, OM, NDF, ADF, and CP, and microbial protein synthesis. Expand
Intake, digestibility and performance of lambs fed with diets containing cassava peels
Sheep farming is designated to economic exploitation, and dry matter intake is the most important factor that influences the performance of animal, thus seeking alternative foods. This study aimed toExpand
Performance and methane emissions of grazing Nellore bulls supplemented with crude glycerin.
TLDR
Crude glycerin supplementation was not effective as a strategy to reduce CH emission in grass-fed cattle, but can be effectively used as a partial energy source in supplement of grazing cattle, promoting an improvement in feed efficiency. Expand

Rumen dynamics of neutral detergent fiber in cattle fed low-quality tropical forage and supplemented with nitrogenous compounds
TLDR
The rumen flow of fibrous particles showed a linear-response-plateau pattern according to the CP levels in diets, and the degradation rate of potentially degradable NDF was linearly increased with the CP Levels in diets. Expand
Technical note: comparison of in vitro and in situ digestibility methods.
TLDR
Results from the four treatments indicate that on average the lag time was 3.5 +/- .3 h less, rate was .03 +/- .002/h faster, and extent was 6.0 +/- .5% greater than for the in situ method for determining NDF digestion kinetics. Expand
Factors affecting disappearance of feedstuffs from bags suspended in the rumen.
TLDR
Measured disappearance of dry matter and nitrogen from soybean meal suspended in dacron bags was lowest when the host animal was fed a high grain diet, while Disappearance of DM and N from SBM and distillers grains in rip-stop nylon bags was greater when these feedstuffs were in the pulverized form rather than in the commercially processed form. Expand
Technical note: forage in vitro dry matter digestibility as influenced by fiber source in the donor cow diet.
TLDR
The source of fiber in the donor cow diet and filtration method can affect in vitro DM digestibility, but relative ranking of forages was unaffected by these variables. Expand
The use of internal markers to predict total digestibility and duodenal flow of nutrients in cattle given six different diets.
TLDR
Three double-marker systems were used to calculate duodenal flows of organic matter, non-ammonia N (NAN), microbial N and NDF, and the most suitable was AIA, followed by INDF6, INDF41 and IADF41, and ADL was the least acceptable marker. Expand
Investigations of the in situ bag technique and a comparison of the fermentation in heifers, sheep, ponies and rabbits.
TLDR
Fiber fermentation using the in situ bag technique was studied in a hay-fed cow and showed that plant fiber containing approximately 50% lignin and 2.9% N entered even 20-micron pores, that rumen contractions increased fiber disappearance and that obstructing liquid exchange limited fermentation.

TLDR
Low apparent (Kjeldahl N) than true (15N) feed N disappearance from the bag suggested a notable proportion of non-feed N in the residues, especially with fibrous feeds with low N. Expand
