A study was designed to collect a database of Iowa feedlot rations for determination of effective neutral detergent fiber (NDF) in complete diets from fiber analysis and particle size determination of individual feed ingredients and compare this with particle size determination of mixed wet rations. Seventy-one beef finishing total mixed rations were collected by ISU Extension Beef Field Specia...
Dietary carbohydrates can be divided into two basic fractions: fibre and nonfibre carbohydrates (NFC). Fibre in dairy cow rations is essential for animal health, since it is required to support an appropriate rumen function and physiology. Therefore, ruminants require fibre in coarse physical form for a more effective chewing and ruminal activity. Increasing fibre content and forage particle si...
An automatic in vitro gas production technique was evaluated for predicting in vivo fiber (NDF) digestibility and effective first-order digestion rate of potentially digestible NDF (pdNDF) of 15 grass silages. Observed in vivo NDF digestibility of the silages harvested at different stages of maturity during 3 yr was determined by the total fecal collection in sheep fed at the maintenance level ...
Four lactating dairy cows that were ruminally and duodenally cannulated were used in an experiment with a 4 x 4 Latin square design to determine the effects of the substitution of neutral detergent fiber (NDF) from forage with NDF from wheat middlings, corn gluten feed, or a blend of distillers dried grains and hominy. Dietary crude protein and NDF averaged 18 and 31%, respectively, for the die...
Sixteen Holstein cows in midlactation were used in a 4 x 4 Latin square design to determine the effect of replacing alfalfa NDF with NDF from whole, linted cottonseed or dried distillers grains. Low and high fiber control diets (13 and 19% of dietary DM from alfalfa haylage NDF, respectively) were compared with diets designed to contain 13% of DM from alfalfa haylage NDF plus 6% of DM from eith...
This study examines the effect of physically effective Neutral Detergent Fiber (peNDF) value roughage on milk composition and yield. The NDF varies depending particle length amount structural non-structural carbohydrates in diet. quality, quantity, are crucial for a healthy rumen. longer is, more cow ruminates saliva it produces. produced is used to balance rumen pH. It aimed protect animal hea...
analyzed as a Latin-square design using PROC MIXED in SAS. Forage quality was analyzed as a completely random design using PROC GLM in SAS. The BMR varieties were lower (P < 0.01) in ADF and NDF at all harvest dates, while N concentrations were not affected (P > 0.41) by variety. The A fraction of DM and NDF was higher (P < 0.01) and the C fraction of DM, NDF, and ADF was lower (P < 0.01) for B...
In this research, samples of sugarcane bagasse were irradiated with various amounts (0, 100, 200 and 300 Kilogray) in an electron accelerator (TT200) to evaluate the effects of electron-beam irradiation on dry matter, neutral-detergent fiber (NDF) and acid-detergent fiber (ADF) degradability parameters. The first samples were dried and then ground for chemical analysis. The ruminal degradation ...

groups, although the difference in NDF at reproductive stage was attributed to the difference in maturity. At Neutral detergent fiber (NDF) concentration is related to intake reproductive stage, the low-NDF groups also had lower potential of forages but might also be related to plant reaction to yield per plant than the high-NDF groups; at the vegetapathogens. Three smooth bromegrass (Bromus in...
