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...

Particle size alterations during neutral detergent fiber (NDF) determination and in situ rumen incubation were analyzed by dry sieving and image analysis to evaluate the in situ procedure for estimation of NDF degradation parameters and indigestible NDF concentration in terms of particle size. Early-cut and late-cut grass silages, corn silage, alfalfa silage, rapeseed meal, and dried distillers...

to increasing total energy content through (i) increasing the contribution of grain and (ii) increasing the digestMaize (Zea mays L.) silage is a high-quality forage for ruminants, ibility of the stover. Much of the variation in forage dibut there have been few significant breeding efforts specifically dedicated to improving maize forage yield or quality by breeders in the gestibility can be ac...

Due to a boom in the dairy industry in Northeast China, the hay industry has been developing rapidly. Thus, it is very important to evaluate the hay quality with a rapid and accurate method. In this research, a novel technique that combines near infrared spectroscopy (NIRs) with three different statistical analyses (MLR, PCR and PLS) was used to predict the chemical quality of sheepgrass (Leymu...

Particle size alterations during neutral detergent fiber (NDF) determination and in situ rumen incubation were analyzed by dry sieving and image analysis to evaluate the in situ procedure for estimation of NDF degradation parameters and indigestible NDF concentration in terms of particle size.

The present study was conducted to identify nutritional value of Rumex obtusifolius in three phenological stages (vegetative growth, flowering, and maturity). Samples were randomly taken in pastures of Saravan in Rasht, Iran in 2015. After drying and grinding, the chemical compositions of Crude Protein (CP), Crude Fiber (CF), Ether Extract (EE), Total Ash (ASH), Neutral Detergent Fiber (NDF), a...

the current study evaluated the effects of electron beam (eb; 10, 20, 30 and 40 kgy), urea and naoh treatments on chemical composition, phenolic compounds, in vitro gas production and in situ ruminal degradability of pistachio by-product (pb). the eb decreased (p < 0.01) neutral detergent fiber (ndf), acid detergent fiber (adf) and acid detergent lignin (adl) contents of pb. treating pb by naoh...

at the research farm of vali-e-asr university of rafsanjan in 2013. the experiment was arranged in a randomized complete block design with four replications and four irrigation intervals. irrigation was done after 40 (control), 60, 80 and 100 mm evaporation from pan class a, from seedling establishment till physiological maturity. results showed that irrigation level did not significantly chang...

The aim of study was to determine ligno-cellulose quality and calorific value cup plant Silphium perfoliatum L., whereas impact nutrition, years sites on the were evaluated as main effects within a huge pilot field experiment. Two complete data sets acid-detergent fiber (ADF), lignin (ADL), crude cellulose (CE), hemicellulose (HEM), neutral-detergent (NDF) high heating (HHV) evaluated, primary ...
