In vitro fermentation systems such as the rumen simulation technique (RUSITEC) are frequently used to assess dietary manipulations in livestock, thereby limiting the use of live animals. Despite being in use for nearly 40 years, improvements are continually sought in these systems to better reflect and mimic natural processes in ruminants. The aim of this study was to evaluate the effect of for...

This experiment evaluated forage production, sward structure, stocking rate, weight gain per area and nutritive value of forage as grazed by beef heifers on Alexandergrass (Urochloa plantaginea (Link) Hitch) pasture fertilized with nitrogen (N): 0; 100; 200 or 300 kg of N/ha. The experiment was a completely randomized design following a repeated measurement arrangement. The experimental animals...

A diversity of forage species and forage ecosystems suited to different management practices exists in the United States. The future of cultivar development in forages includes the new and evolving areas of genomic and transgenic technologies. Genomic research gained momentum with the publication of the complete DNA sequence of the human genome and has since expanded to plant species including ...

interval and that total forage production was higher for plots harvested at 6-wk compared with 4-wk intervals. Eastern gamagrass [Tripsacum dactyloides (L.) L.] is a perennial, The effects of plant population density on horticulwarm-season bunchgrass native to the Americas. Although much is tural and field crops is well established (Wade et al., known about the effects of fertilization and harv...

1Animal Sciences Department, NDSU 2Carrington Research Extension Center, NDSU 3Hettinger Research Extension Center, NDSU 4Department of Animal Science, South Dakota State University The objective of this study was to evaluate the effect of feeding different levels of forage during the finishing phase of beef production. Three different finishing diets of 20, 30 and 40 percent forage were fed to...

Brown midrib, a genetic mutation in several grassy species, reduces lignin content in the total plant parts. Lignin is mostly indigestible but also plays an important role in plant rigidity. During the past several years the brown midrib (bmr) trait has been incorporated into forage sorghum, sudangrass, and corn. The results have been significant for the most part. IVTD values for bmr sorghum h...

This research was conducted to identify the limitative factors of forage productionsuitability in order to achieve the sustainable exploitation of natural ecosystems in AliabadWatershed in Lorestan in 2013. The field measurements have been done through cutting andweighing method to estimate the forage amount, four-factor method to determine the rangecondition, trend scale to specify the orienta...

and Implications Forage mass and nutritional quality were measured in the total forage monthly from May through September and in live forage in the upper half of the sward in June and August and related to body weights, body condition scores and daily methane emissions in pastures grazed at a stocking rate of 1.98 cows per hectare by continuous, rotational or strip-stocking at a limited forage ...

red clover (trifolium pretense) has wide adaptability to different soil and climatic conditions, and suitable digestibility of forage compared to the other clover species. new red clover cultivar, nasim, was primarily selected from clover germplasm received from food and agriculture organization (fao), the united nations, in seed and plant improvement institute, karaj, iran. agronomic and yield...
