Forage Quality and Feeding Management for Eastern Gamagrass in Wisconsin
Throughout Wisconsin, chopped straw often is purchased as forage and used within diets of dairy cattle to provide additional fiber, and maintain proper rumen function. For replacement heifers, straw is used commonly to dilute the energy density of the diet, limit voluntary intake, and prevent over-conditioning, especially within diets constructed for pregnant heifers weighing >1000 lbs. Unfortu...
متن کاملEastern Gamagrass
warm-season bunch grass native to the eastern United States and is still often found east of Kansas and Oklahoma. This highly productive grass is best adapted to wet habitats; and remnant colonies are commonly found in flood plains and along stream banks. Eastern gamagrass is a relative of field corn (Zea mays) and is characterized by numerous short, well-developed rhizomes. Lower culm internod...
متن کاملDetermining suitable time for exploitation/ grazing of rangeland plants using growing degree days (GDD) model
One of the key principles in rangeland management is determination of suitable times for exploitation and grazing of rangeland plants in summer and winter pasturelands. This determination of time not only prevents degradation of plant species, but also leads to optimal usage of plant yield. Multiple factors affect plant phenology among which temperature regime has the highest effect on plant de...
متن کاملGrowing degree-days: one equation, two interpretations
Heat units, expressed in growing degree-days (GDD), are frequently used to describe the timing of biological processes. The basic equation used is GDD = [(T,,, + TM,,)/2] T,,,,, where T, and T,,, are daily maximum and minimum air temperature, respectively, and T,, is the base temperature. Two methods of interpreting this equation for calculating GDD are: (1) if the daily mean temperature is les...
