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% +/...

Crude protein (CP) of forages can be separated into fractions of differentiated abilities to provide available amino acids in the lower gut of ruminants. This knowledge is critical to develop feeding systems and to predict animal responses. We have measured during two growing seasons (1996 to 1997 and 1997 to 1998) the CP fractions of common vetch fresh forage with the objective being to assess...

This study aimed to evaluate the performance of Balinese bulls fattened by various forages on traditional farms. The was experimental research using Clitoria ternatea, Zea mays fresh straw, Pennisetum purpuphoides, purpureum, Sesbania grandiflora, Centrosema pubescens, Leucaena leucocephala, and natural grass fatten livestock which were arranged for farmers' habits in fattening. Variables measu...

It is difficult to make good quality of silage from alpine gramineous from the Qinghai Tibetan plateau. The effects of lactic acid bacteria (LAB) on the fermentation quality and aerobic stability of Siberian wildrye silage were studied in southeast of the Qinghai Tibetan plateau. Siberian wildrye materials were freshly cut at the sprouting stage, flowering stage, and milky stage. Silage was pre...

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...

Polyploidy means having more than two basic sets of chromosomes. Polyploid plants may be artificially obtained through chemical, physical and biological (2n gametes) methods. This approach allows an increased gene scope expression, thus resulting in phenotypic changes such as yield product quality. Nonetheless, breeding new cultivars induced polyploidy should overcome deleterious effects that a...
