†Background Forage plant breeding is under increasing pressure to deliver new cultivars with improved yield, quality and persistence to the pastoral industry. New innovations in DNA sequencing technologies mean that quantitative trait loci analysis and marker-assisted selection approaches are becoming faster and cheaper, and are increasingly used in the breeding process with the aim to speed it...
Search for an adapted forage species for feed production under existing marginal lands and harsh conditions is needed to overcome sever feed shortage in Egypt. Sesbania, Sesbania aegyptiaca (Sesbania sesban, L) has shown potential for forage production and being included in grazing systems, especially on marginal lands and salt–affected soils. An experiment was conducted in the summer of 2004 a...
On a farm in Slovenia two cows died overnight without any previous signs of disease. The cows were fed green forage, containing a big portion of redroot pigweed (Amaranthus retroflexus) at least for four consecutive days. Poisoning with this plant was suspected. Pathomorphological changes established by the necropsy of both cows confirmed the suspi-
In the rangelands of Iran, the lack of appropriate grazing management is one of the major problems ultimately leading to untimely and excessive grazing intensity of forage. Accordingly, most of the rangelands show a retrogression trend and poor conditions. In forage species, phenological stage is one of the most important criteria for range management. Bromus tomentellus species is an ...
Sainfoin (Onobrychis viciifolia Scop.) is a perennial legume widely adapted to environmental conditions and has been successfully used as a pasture and hay forage in Iran. This experiment was carried out to investigate yield potential and genetic variation of morphological, agronomic and qualitative traits using 10 Iranian sainfoin populations. The experiment was conducted as a randomized compl...
Voluntary intake of forage by ruminants is limited by forage bulk density and the rate at which forage is degraded to particles that can pass from the rumen. Two indirect laboratory measures of intake, neutral detergent ®ber (NDF) concentration and particle-size reduction index (PSRI), are being used in plant breeding programs. The objective of this study was to determine the relationship among...
and Implications Forage mass and nutritional quality were measured in the total forage monthly from May through September and in live forage in the upper half of the sward in June and August and related to body weights, body condition scores and daily methane emissions in pastures grazed at a stocking rate of 1.98 cows per hectare by continuous, rotational or strip-stocking at a limited forage ...
Smirnovia iranica, a native valuable woody species from Fabaceae, is an adaptable plant of central sandy areas of Iran. On other hand, this species could be markedly considered from different view points of forage production, soil conservation and medicinal applications. The current research was carried out in Band-e-Rig of Kashan, Iran to evaluate Smirnovia iranica properties including crude p...
To study the effects of plant densities and planting orientation on the seed and forage yield of sorghum, an experiment was conducted at Hossein- Abad – Shahcal village –90 kilometers south of Bam-in 2002. The experiment was a factorial with randomized complete block deisgn and three replications. The treatments were: orientation with three levels (South-North, East – West, Northeast – Southwes...
BACKGROUND Numerous hypotheses have been proposed to explain the wide variation in the ability of plants to forage for resources by proliferating roots in soil nutrient patches. Comparative analyses have found little evidence to support many of these hypotheses, raising the question of what role resource-foraging ability plays in determining plant fitness and community structure. SCOPE In the...
