SOILS are usually considered to influence animal nutrition through the quantity and quality of the herbage they produce, so that the sequence is soil-plant-animal. The fact that soil is ingested by grazing animals indicates that a direct soil-animal effect also needs to be considered. Soil is taken in by animals along with herbage, as soil adhering to leaves, as soil on roots, and as earthworm ...

The analysis of mixed pasture species has proven to be a useful guide to plant and animal nutrition. Fourteen or more elements can be analysed in plants and the results used to correct any potential problem. In Southland low Ca MQ. Co and Se are the main problems in animal nutrition, with low Sand MO the main deficiencies in plant nutrition. Most elements in pasture vary with soil temperature i...

Historically, many nutritional scientists studied basic animal nutrition; however, as nutritional science has evolved and become more specialized, fewer nutritional scientists are trained in basic animal nutrition. Today an important area of animal nutrition is the development of models to examine the nutritional effects in human health and disease. Despite this increasing area of focus, there ...

determination of forage quality of available species is one of the fundamentalfactors for the management of rangelands. near-infrared reflectance spectroscopy (nirs)was used to analysis the nitrogen (n), acid detergent fiber (adf), dry matterdigestibility (dmd) and metabolizable energy (me) content of three phenological stages(vegetative, flowering and seeding) of bromus tomentellus samples in ...

in this study, the chemical composition of the tea wastes determined. the value of dry matter, organic matter, crude protein, crude fiber, calcium and phosphorous 95, 94, 13.3, 23.1, 0.011 and 0.29 percent, respectively. in the experiment of digestibility by animal, five experimental rations (including tea waste and alfalfa in the proportion of 0:100, 10:90, 20:80, 25:75 and 30:70 percent) and ...
