To determine the importance of digestion and detrition (rubbing) in the rumen on the breakdown of large particles (LP) in the leaf and stem fractions of temperate and tropical forages, a study was made using a digestion-detrition simulator. Large-particle breakdown was measured in forage samples subjected to 48-h digestion or 48-h digestion plus detrition. Digestion caused a breakdown of 14% +/...

Forage age and maturity generally have a larger influence on forage quality than environmental factors. Plant environment, however, cause deviations in forage quality even when harvested at the same maturity. Temperature usually has greater influence on forage quality than other environmental factors. Although increasing temperature normally hastens maturity, the primary effect may be through i...

Tannins, a group of chemical compounds produced by a number of broadleaf forage plants, can bind proteins. Typically, grasses don’t contain tannins, although sorghum (Sorghum bicolor) has a significant tannin content. Tannins are often found in higher concentrations in broadleaf plants adapted to warm climates. For example, sericea lespedeza (Lespedeza cuneata) is a forage cultivated in the mid...

Poultry litter and fertilizers are normally added as soil amendments. The effects of poultry inorganic on three mixed-season perennial forages were studied for two years in the field to understand growth dynamics, metals, nutrient uptake. primary objective was investigate heavy metal concentrations, biomass yield forage potential a cool-season forage, stinging nettle (Urtica dioica L.), relativ...
