samples of salvia leriifolia were collected from khorasan mountains in different growing stages. chemical composition, rumen degradability characteristics of dry matter (dm), crude protein (cp) and neutral detergent fiber (ndf) of salvia leriifolia whole plant (stem and leaves) in different flowering stages and plant leaves in comparison with alfalfa hay and triticale straw were measured using ...

OBJECTIVE The impact of forage feeding strategy on growth performance, ruminal fermentation and nutrient digestibility in post-weaning calves was investigated. METHODS Forty-five female Holstein calves (body weight [BW] = 79.79±0.38 kg) were enrolled in the 35-d study at one week after weaning and randomly assigned to one of three dietary treatments. All diets were fed as total mixed ration c...

Alfalfa hay is a major crop supporting U.S ruminant livestock industry, particularly dairy. Several cellulosic feedstocks will be needed to meet current ethanol production goals. Alfalfa has considerable potential as a feedstock for production of ethanol and other industrial materials because of its high biomass production, perennial nature, ability to provide its own nitrogen fertilizer, and v...

Crude fibers (CF) take a special place in the growing rabbit`s nutrition. In depend on their origin and composition, CF have digestibility 1725% in the roughages and up to 40-50% in the green and concentrate feeds. They are very important in the regulation of the processes of both digestibility and bacterial synthesis. The optimal CF quantity for growing rabbits is 12-15%. Alfalfa hay is prefer...

Attaining high-quality alfalfa hay is a critical aspect of profitability for alfalfa and animal productivity. Attributes of quality include energy, voluntary intake, CP, fiber and minerals. Forage quality has many attributes and should be evaluated through laboratory measurements and subjective observations such as odor mold and weed content. Measurements of plant cell wall (NDF), as well as AD...

Two experiments determined effects of collection and preparation techniques on nutrient composition of masticate samples from esophageally fistulated cattle. In Exp. 1, 12 esophageally fistulated cattle were maintained on 2 precollection diets, high CP (24% CP; = 6) or low CP (7.7% CP; = 6), for 8 d. On d 9, the esophageal plug was removed, screen bottom bags were attached, and each cow was off...

the objectives were to investigate the effects of addition of alfalfa hay as an absorbent on fermentationquality and effluent production of corn silage. three levels of corn forage with dry matter (dm) contentsof 18.3, 21.7 and 25.5 percent were supplemented with 0, 5, 10, and 20 percent alfalfa hay, on as fedbasis, and ensiled in three replicates in polyvinyl chloride mini-silos in a completel...

The effects of dietary extruded linseed (EL) on growth performance, meat quality, and lipid profile of Semimembranosus and Longissimus lumborum muscles of 81 Sarda lambs were studied in a 3 × 3 design: EL content (0%, 10%, and 20%) of maternal dietary concentrate fed from 20 d to parturition to 60 d of lactation and EL content (0%, 10%, 20%) of lamb concentrate fed after weaning for 30 d. The b...

Eliminating toxins from the hay begins in the field. However, toxic weeds frequently end up in hay and forage and pose a serious risk to livestock. The effects of poisonous plants on animals depend on the amount ingested and the individual weed present in hay. Many indications for poisoning exist. Obvious cases involve sudden onset of disease in a number of animals. Finding of common feed or en...

Twelve early lactation Holstein cows (4 fistulated) were used in replicated 4x4 Latin squares with 4-wk periods to determine the effective neutral detergent fiber (NDF) content of wet corn gluten feed and to measure the effect of forage particle size on ruminal mat consistency and passage rate of wet corn gluten feed. Diets were 1) 23.3% NDF (17.4 percentage units of NDF from alfalfa silage), 2...
