Eight hundred and fifty two multiparous Holstein cows in mid-lactation were used in a completely randomized and nested design with two treatments and three replications. Treatments were: 1) Isfahan and 2) Borkhar-Meymeh. Replications were: 1) class of one to five cows 2) class of six to ten cows and 3) class of eleven to twenty cows. Paired t-test was used for the comparison of nutrient consump...
Sixty Holstein cows were assigned to two treatments at 21 d before calving and were group-fed a prepartum diet with or without yeast culture. After parturition, cows were individually fed one of five treatments for 140 d: 1) 21% forage neutral detergent fiber (NDF) without yeast culture, 2) 21% forage NDF with yeast culture, 3) 17% forage NDF without yeast culture, 4) 17% forage NDF with yeast ...
Twelve early lactation Holstein cows (4 fistulated) were used in replicated 4x4 Latin squares with 4-wk periods to determine the effective neutral detergent fiber (NDF) content of wet corn gluten feed and to measure the effect of forage particle size on ruminal mat consistency and passage rate of wet corn gluten feed. Diets were 1) 23.3% NDF (17.4 percentage units of NDF from alfalfa silage), 2...
This study was conducted in two separate experiments. Four rumen-cannulated sheep were allocated in the first experiment to evaluate date by-product (DBP) and date seed (DS) nutrients degradation in rumen. In experiment two eighteen fattening lambs were allocated in three different treatments (6 animals/treatment) to evaluate DBP effects on animal performance and nutrients’ digestibility. Three...
The National Drug File Reference Terminology (NDF-RT) presents a large set of drug classes which can potentially be used in clincal settings. Using semantic web technologies such as XML (eXtensible Markup Language) and RDF (Resource Description Framework), the drug classes in NDF-RT were enriched for the purpose of comparison to themselves and to drug classes in other terminologies. Methods and...
We quanti®ed the effect of dietary non®ber carbohydrate (NFC) concentration (30, 35, 40, or 45% of DM) on in vitro digestion kinetics of neutral detergent ®ber (NDF) from alfalfa and corn silages at pH 5.8 or 6.8. The objective was to simulate the effect of diets differing in effective ®ber content on the optimal NFC-to-NDF ratio that resulted in maximal ®ber digestion. Ash-free NDF was determi...
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...
The objective of this study was to compare in situ and in vitro methods for determining rate and extent of forage digestion in the rumen of beef cattle. Duplicate polyester (10 × 20 mm) or ANKOM F57 filter bags containing 5.0 or 0.5 g of ground (2mm) bromegrass hay, respectively, were incubated in situ or in vitro (ANKOM Daisy Incubator) for 3, 6, 9, 12, 15, 18, 24, 36, and 96 hours. Bags were ...
This split unit study involved two sheep, seven incubation times and four test straws to compare with untreated straw the effect, kgÿ1 straw dry matter (DM), of CaO (160 g CaO plus 2 l of water), NaOH (80 g NaOH in 3 l of water) and alkaline hydrogen peroxide (NaOH plus 132 g H2O2 in 3 l of water, AHP) treatments on composition and rumen degradation in sacco of wheat straw in sheep. After 14 da...
