Concentrated sources of dairy manure represent significant water pollution potential. The southern United States may be more vulnerable to water quality problems than some other regions because of climate, typical farm size, and cropping practices. Dairy manure can be an effective source of plant nutrients and large quantities of nutrients can be recycled through forage production, especially w...

the onobrychis viciafolia is one of the forage and rang land plants that is adapted and spread to different climates of iran. one of the important disease of this plant is powder mildew in the lorestan province which damages second and next cutting stages of this plant. to study the correlation between disease severity and forage quality, seeds of 34 populations were planted in field of khorram...

Climate-induced shifts in plant phenology may adversely affect animals that cannot or do not shift the timing of their reproductive cycle. The realized effect of potential trophic "mismatches" between a consumer and its food varies with the degree to which species rely on dietary income and stored capital. Large Arctic herbivores rely heavily on maternal capital to reproduce and give birth near...

The lamb production potential and forage quality of a forage system consisting of AU Triumph fescue and Tifton 44 bermudagrass was studied over a period of two consecutive years. Each spring, 60 yearling Suffolk ewes and 40 wethers were divided into two groups and allowed to graze two replicated 1ha AU Triumph paddocks continuously. At the end of the spring grazing season, both groups were tran...

The ability of grazing animals to enhance quality of diet by selection is important in production. The study determined the effects of selection on dietary quality of cattle grazing monocultures of smooth bromegrass (Bromus inermis Leyss; SB), switchgrass (Panicum virgatum L.; SG), and big bluestem (Andropogon gerardii Vitman; BB) as influenced by plant maturity. Three ruminally-fistulated stee...

This experiment was conducted to determine the effects of nitrogen and phosphorus fertilizers on nutritive value of safflower forage and silage by in situ and in vitro methods. The safflower forage was harvested at flowering stage, chopped to 3-5 cm particles and then ensiled in the laboratory silos for 60 days. The experimental treatments included: 1. Unfertilized forage (control), 2. Phosphor...

in order to study the yield and forage quality of intercropping barley (hordeum vulgare) and mustard (sinapis alba) in different planting dates, a factorial experiment based on randomized completely block design with three replications was carried out at farm research station, gonbad -e- qabus university. factors were included as three planting dates (15 november, 6 and 20 december 2006) and fo...

to increasing total energy content through (i) increasing the contribution of grain and (ii) increasing the digestMaize (Zea mays L.) silage is a high-quality forage for ruminants, ibility of the stover. Much of the variation in forage dibut there have been few significant breeding efforts specifically dedicated to improving maize forage yield or quality by breeders in the gestibility can be ac...

Land, livestock, and wildlife managers need to understand the nutritional dynamics of forages to sustain adequate growth and reproduction of their animals and/or assure equitable payment for forages. Despite a long history of livestock grazing in the northern Great Basin, seasonal and annual nutritional dynamics of many of the region’s prominent grasses have not been described. We addressed thi...

to study the effect of three soil fertilizing systems (chemical, organic, and integrated) on forage yield and quality of globe artichoke (cynara scolymus) an experiment was conducted using a randomized complete block design (rcbd) of four replications at the research farm of college of agriculture, university of tehran, karaj, iran in 2006. the treatments included 5 levels of chemical fertilize...
