Five common range forage including Agropyron intermedium, Bromus tomentellus, Hordeum bulbosum, Cousinia bakhtiarica and Scariolla orientalis, were sampled during three phenological stages, from controlled rangeland stations over five locations in Chaharmahal and Bakhtiari province, Iran. All samples were chemically analyzed for Crude Protein (CP%), in vitro Dry Matter Digestibility (DMD), Organic Mater Digestibility (OMD), Ether […]
This study was conducted to compare forage quality of two native halophyte species Camphorosma monspeliaca and Limonium iranicum collected from Meighan saline rangelands near Arak city in center of Iran. Edible biomass of both species was sampled on three phonological stages (vegetative growth, full flowering and seed ripening). Forage quality indices such as Crude Protein […]
Abstract. Information on forage quality in phenological stage could help range managers to choose suitable grazing method to achieve higher animal performance without detriment to vegetation. Vetiver grass (Vetiveria zizanioides) is a non-native perennial grass that was introduced to the Iran in 2008. This plant is a multi use species that could be considered from […]
Information on quality characteristics of forage species help the range managers to select a suitable grazing program that minimizes the damages to vegetation. Water Soluble Carbohydrates (WSC) -the main photosynthetic products- are stored in various plant parts and are more likely to be consumed when plants require them. In order to investigate the changes of […]
Determination of forage quality of plant species in natural habitats such as rangelands and deserts is one of the most important factors for grazing management of these ecosystems. For this purpose, the nutritional values of Calligonum comosum in three phenological stages (vegetative growth, flowering, and seedling) were determined in desert habitats located in the northeast […]
Studying plant phenology is very important to regulate the rangeland utilization. Plant phenology can be determined by Growing Degree Days (GDDs). Since temperature varies yearly, the phenological stages may consequently differ yearly. Determining the base temperature is one of the key steps in the calculation of GDDs. The aim of this study was to calculate […]
The information about the forage quality of rangeland species is essential to supply a reasonable diet to livestock and determine thestocking rate and grazing time on rangelands. Salsola turcomanica is one of the important species of semi-arid rangelands in the Western part of Golestan province, Iran. The present study was conducted to provide information about […]
In order to compare the effect of sowing date on plant growth, development stages and forage yield of three Astragalus cyclophyllon G. Beek ecotypes, a study was conducted in 2010-2011 cropping years in Hanna station, Semirom county, Iran. Three Astragalus ecotypes were originated from Hanna, Golpayegan and Chadegan in Isfahan province, Iran. Seeds were sown […]
