Two digestion experiments were conducted to determine the effect of various levels of potato processing residue in feedlot diets on digestion of dry matter, gross energy, crude protein and starch. In Exp. 1, 10 Hereford steers (average weight 360 kg) were randomly allotted to one of five diets in which (1) 0, (2) 15, (3) 30, (4) 45 or (5) 60% of diet dry matter was provided by potato processing...

Near-infrared transmittance (NIT) spectroscopy was used to predict the percentage in weight of the fat, dry matter, protein and fat/dry matter contents in Zamorano cheeses, protected with a Designation of Origin by the European Union. A total of 42 cheeses submitted to official control were analysed by reference methods. Samples were scanned (850-1050 nm) and predictive equations were developed...

Individual growth and feed intake of 36 Angus, 27 Polled Hereford and 30 Holstein steers were determined from 365 to 560 kg live weight. One-half of the cattle in each breed were fed a diet based on high-moisture ear corn and the other one-half were fed a diet based on corn silage. Within each breed X diet group, half of the cattle were implanted with zeranol. Cattle fed the high-moisture ear c...

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 ...

%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...

concentration of co2 in the atmosphere is likely to increase up to 550 µmol mol-1 by the middle of 21st century. such an increase in the atmospheric co2 would affect plant growth, and as well the productivity of crop plants. a field experiment was conducted with two potato cultivars namely kufri surya and kufri chipsona-3 grown inside open top chambers (otcs) at ambient (385±30 µmol mol-1) vs. ...

Weeds are a major problem in seeding rangeland and cropland to native grasses. However, many immature weedy forbs and grasses are palatable to cattle. Research was conducted using yearling cattle for weed control in big bluestem (Andropogon gerardii var. gerardii Vitman) seedings (1987, 1988) at Mead, Nebraska on a Sharpsburg silty clay loam (fine, montmorillonitic, mesic Typic Argiudoll) soil....

Implementation of water-saving irrigation practices in lowland rice results increased availability nitrate (NO3−) the soil and favours germination upland weeds. Since plant species show a specific preference for either ammonium (NH4+) or NO3− as nitrogen (N) source, changes both concentration weed flora may affect competition between Further, transpirational demand atmosphere might growth compe...
