This study presents the chemical composition and in vitro fermentation of five diets with different forage (alfalfa) to concentrate (faba bean) (F:C) ratios, F0:C100, F25:C75, F50:C50, F75:C25, F100:C0 on a dry matter (DM) basis. Results indicate that the chemical composition in term of organic matter (OM), ether extract (EE), crude protein (CP), acid detergent fiber (ADF), neutral detergent fi...

Correlations between kernel vitreousness and ruminal in situ (RDMD) and total tract dry matter (TDMD; sum of ruminal in situ and post-ruminal in vitro measurements) degradabilities were determined for 33 diverse corn germplasm sources. These included a wide range of endosperm characteristics from opaque 2 (o2) types to densely packed flint types, and a number of intermediates. Harvests were don...

Alfalfa, red clover, orchardgrass and timothy were harvested in the vegetative stage, wilted and stored as hay, or ensiled in small batch silos (20 kg) at 60, 40 or 20% (direct cut) dry matter and were analyzed for compositional differences. A ruminally cannulated lactating cow, consuming 50% of her dry matter intake from hay crop silage, was used to measure in situ dry matter, N, neutral deter...

In order  to study the effect of drought stress on some growth indices of oil sunflower cultivars, a study was conducted in Isfahan. The experiment was conducted as split plots in a randomized complete blocks design with three replications in Isfahan (51° 48' E, 32° 40' N).Main plots were drought stress in four levels (80, 100, 120, and 140 mm evaporation from evaporation pan class A and cultiv...

dry matter remobilization, grain filling rate and duration has principle role on rice grain yield, and environment condition directly affect on them. for study the influence of climate factors a factorial field experiment in randomized complete blocks design with three replications conducted at haraz extention and technology development centre in spring 2013. treatments included rice cultivars ...

The economy of C and N in nodulated cowpea (Vigna unguiculata [L.] Walp.) was described in terms of fixation of CO(2) and N(2), respiratory losses of C, and the production of dry matter and protein.Net daytime gain of C by the shoot (net photosynthesis) rose to a maximum at flowering and then declined sharply due to abscission of leaves. Maximum N fixation occurred 10 days prior to maximum net ...
