Abstract The supplementary feeding costs of small ruminants can be substantial when there is not much vegetation available for grazing or browsing. However, such have been reported well and the strategies to minimize them discussed enough. objective this study was quantify involved in supplementing under grazing-based production systems. Grazing studies were conducted from July October 2021 (88...

Concentrations of selected trace minerals (Cu, Fe, Zn, Mn, Co, Se) were determined from annual cool-season grass pasture forages over four consecutive winter-spring grazing seasons (2001-2005). Twice monthly forage samples were taken from eight experimental pastures used in beef cattle grazing trials. Two, 2-yr experiments were conducted; animal and pasture data were reported previously. Each e...

The objective of this study was to determine nursing calf forage intake prior to weaning in the Nebraska Sandhills range. Eight crossbred cow-calf pairs in year one and 12 pairs in year two were selected for each trial. Pairs were randomly assigned to one of two rotation groups, pasture (Graze) or individual fed dry lot pens for each pair (Pen). Pen pairs were fed harvested meadow hay of simila...

Hedysarum flexuosum L. is an important forage legume with high nutritive value. The determination of forage production in natural habitats is the most important factor for grazing management. Studies on its habitat characteristics and distribution are scarce. This research was conducted in order to evaluate the extent of pheno-morphological diversity in natural populations of Hedys...

In New Zealand, agriculture is predominantly based on pastoral grazing systems and animal excreta deposited on soil during grazing have been identified as a major source of nitrous oxide (N2O) emissions. Forage brassicas (Brassica spp.) have been increasingly used to improve lamb performance. Compared with conventional forage perennial ryegrass (Lolium perenne L.), a common forage in New Zealan...

introduction cultivated alfalfa (medicago sativa l.) is the main, most of the time the only, forage for ruminants in iran as well as many other parts of the world. harvesting high quality forage is critical for iranian dairy industry, because it affects the performance of animals and reduces amount of concentrates utilization in dairy diets. unfortunately the most parts of the concentrates ingr...
