In order to map the genomic regions affecting barley forage quantity and quality, two experiments were conducted with 72 doubled haploid lines and their two parents (‘Steptoe’ and ‘Morex’), at the Research Farms of the Faculty of Crop and Animal Sciences, University College of Agriculture and Natural Resources, University of Tehran and Agriculture and Natural Resources Research Station of Sista...
Forage plays a critical role in the milk production of dairy cows; however, the mechanisms regulating bovine milk synthesis in dairy cows fed high forage rations with different basal forage types are not well-understood. In the study, rice straw (RS, low-quality) and alfalfa hay (AH, high-quality) diets were fed to lactating cows to explore how forage quality affected the molecular mechanisms r...
Six classes of current herbaceous and woody forage were collected seasonally from a 5-yearold mixed loblolly (Pinus taeda) -shortleaf pine (Pinus echinata) plantation (in Texas) and subjected to nutrient analyses and nylon bag dry-matter digestion trials. Forages were most nutritious and digestible in the spring when tissues were succulent and growing rapidly. Browse leaves and twig tips were t...

Either option leaves a forage Hard red winter wheat (Triticum aestivum L.) is a major cooldeficit period until warm-season perennial grasses are season forage that couples with warm-season perennials to provide livestock feed in the Southern Plains. Productivity and quality of available for grazing in mid summer. wh...
Semi-arid rangelands show much spatial heterogeneity, with some parts producing more and better quality food for herbivores. The concepts of ‘Key Resource’ and ‘Key Resource Area’ have been developed to describe a resource that ‘provides good-quality forage’ and that ‘reduces (inter-)annual variation in forage supply’. Illius and O’Connor (1999) formalised these concepts, arguing that in key re...
Forage quality is one of the most important factors that is necessary for proper nutritional management of livestock from rangelands. The most important quality factors of plants are crude protein, ADF, crude fiber, metabolic energy and digestible dry matter. The present study was conducted to evaluate the forage quality of high-yielding herbaceous species (Astragalus brevidens and Astragalus v...
