the aim of this paper was to study of the effect of fenugreek seed (trigonella foenum-graecum) and asparagus root (asparagus officinalis) on in vitro digestibility and kinetics of gas production of alfalfa hay. fenugreek seed (fs) and asparagus root (ar) were added at different levels (0, 5, 10, 15 and 20% of dm). total phenolic components of alfalfa hay (ah), fenugreek seed (fs) and asparagus ...

The two greatest silage problems are shrinkage (dry matter losses) and heating (aerobic spoilage). Therefore, one of the main aims of silage making is to reduce losses of dry matter during the preservation process. Dry matter losses occur during the three main stages of silage preservation namely the aerobic respiration stage after cutting, the anaerobic fermentation stage after sealing, and th...

Published data on the effects of essential oils (EO) on in vivo nutrient digestibility in sheep are contradictory. In 2 experiments, the effect of thymol and carvacrol on nutrient digestibility was studied in sheep fed with high (70%) or low (52%) concentrate diets, using incomplete Latin Square designs. The essential oils were mixed with the concentrate portion of the diet at the rate of 0.0, ...

quality of protein fractions, according to cornell net carbohydrate and protein system (cncps), and digestibility coefficients, using tilley and terry procedure, of the fresh and ensiled amaranth (amaranthus hypochondriacus) forage were assessed. the concentration of crude protein (cp) and true protein (tp) in the fresh forage, were respectively 116 and 70 g/kg of dm. soluble protein (sp) and a...

the nutritive values of non- processed and processed grape pomace with neurospora sitophila were evaluated. the chemical compositions and physical characteristics of samples were evaluated by laboratory analysis. an in vitro digestibility experiment was done to determine digestibility coefficients of dry matter, organic matter and also digestible organic matter in dry matter (domd) to estimate ...

Bag silos made at three research farms in 2000 and 2001 were monitored at filling and emptying to determine densities and losses. A total of 47 bags (23 alfalfa, 1 red clover, 23 whole−plant corn) were made, and losses were calculated on 39 of the silos. Dry matter (DM) density ranged from 160 to 270 kg/m3. Dry matter density increased with DM content in hay crop silages on average 2.9 kg/m3−% ...

%Moisture & %Dry Matter Labs determine the %moisture content of submitted samples by drying the sample, and calculate the %dry matter; (DM% = 100 %moisture). Most lab analysis reports list test values on both the basis of %Dry Matter, and “As Fed”, “As Is” or “As Received.” Forage nutritive values should be evaluated, and rations balanced on a dry matter basis. Once the forage needs have been d...

in order to study of yield, yield component, plant height, total dry matter and radiation use efficiency with 13 spring varieties of rapeseed ,an experiment was carried out in 2007 growing season at agriculture and natural resources research station of torogh,mashhad. these cultivars were from three rapeseed species belonged to brassica napus, brassica rapa and brassica juncea. experimental des...
