Alfalfa and bromegrass, each harvested at five different stages of maturity, were separated into water-insoluble and -soluble fractions. The NDF concentrations ranged from 19 to 43% for alfalfa and from 42 to 58% for brome. The rates of digestion, by mixed ruminal microflora, of the unfractionated forage and of the water-insoluble and -soluble fractions were measured in vitro using pressure sen...

The effects of exogenous proteolytic enzyme (EPE) on intake, digestibility, ruminal fermentation, and lactational performance were determined using 8 lactating Holstein cows in a double 4 x4 Latin square experiment with a 2 x2 factorial arrangement of treatments. Diets based on barley silage and alfalfa hay as the forage sources were formulated to maintain different forage to concentrate ratios...

the objective of these investigation were use of berseem clover (trifolium alexandrinum ) in double cropping system (after autumns crop) to improve forage production in shahrekord region. the experiments were carried out in the preliminary, research and farmer field condition in 2005, 2006-7 and 2013 respectively. in 2005 the results showed that there is possibility of double cropping of bersee...

A long-term study of four degraded streams in the upper Owens River watershed documented the recovery of riparian habitats and significant improvement in channel morphology in response to grazing strategies, recreation management, and pre-irrigation peak flows. Increased control of livestock distribution, timing of forage use and degree of forage utilization on and near stream banks was designe...

In the northwest of Mexico, a desert zone, new alternatives are required to satisfy the needs of food in goats; evidence indicate that feeding with Salicornia bigelovii forage, could be a contribution to goat obtaining system. Regarding to this halophyte, the information related to its use as a forage supplement in Sonora desert is very limited, specifically in goats. The goal of this ...

The aim of this experiment was to investigate rumen fermentation and some blood parameters of dromedary camels fed with C3 and C4 forage. Four fistulated dromedary adult camels were fed with diets as a changeover design, 30 days for each period. The diets included alfalfa hay + wheat straw (C3 forage) and atriplex+ suaeda + seidlitzia (C4 forage). At ...

The aim of this study was to determine possible differences between first cut and second cut forage of Birjand ecotype of Kochia scoparia for chemical composition and fermentability, and to evaluate the changes may be induced by N fertilization in chemical composition, fermentability, and utilizable crude protein (uCP) supply at the duodenum of dairy cows of Sabzevar ecotype of Kochia....

The role of ruminal bacteria in the frothy bloat complex common to cattle grazing winter wheat has not been previously determined. Two experiments, one in vitro and another in vivo, were designed to elucidate the effects of fresh wheat forage on bacterial growth, biofilm complexes, rumen fermentation end products, rumen bacterial diversity, and bloat potential. In Exp. 1, 6 strains of ruminal b...

three grass species, agropyron desertorum (agde) and agropyron elongatum (agel) and recently, bromus tomentellus (brto) are mainly used for range improvement as mixed seeding in semi-arid areas of iran. because there is little information about management of these grasses, this study was conducted at the sisab research station in northern iran to evaluate their responses to grazing management a...
