چکیده

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 completely randomized design.concentrations of ash and total nitrogen increased and that of neutral detergent fiber decreasedsignificantly as the level of absorbent increased (p< 0.05). increasing the level of absorbent significantlyincreased the dm of silage where the higher levels of dm were observed in silages with 10 and 20percent absorbent. the ph values were within the optimum range of corn silage (ranging from 3.79 to4.33); however, silage ph was affected by the interaction between dm and level of absorbent (p

Use of exogenous fibrolytic enzymes to enhance in vitro fermentation of alfalfa hay and corn silage.

Two in vitro experiments were performed to identify promising exogenous fibrolytic enzyme products (EFE) and optimum dose rates (DR) for improving the degradation of alfalfa hay and corn silage. The relationship between enzymatic activity and fermentation responses was examined to identify optimum formulations. In experiment 1, 5 EFE containing mainly endoglucanase and xylanase activities, with...

Synthesis of microbial protein in ruminally cannulated cows fed alfalfa silage, alfalfa hay, or corn silage.

Six ruminally cannulated cows were used in an experiment with a 3 x 3 Latin square design. Three all forage diets-alfalfa silage, alfalfa hay, or corn silage plus 2.2% urea (DM basis)-were fed for ad libitum intake four times daily. The microbial protein marker 15NH3 and the liquid marker Cr-EDTA were infused continuously into the rumen for 72 and 48 h, respectively; the solid marker, Yb-labele...

The Effects of Indigestible Neutral Detergent Fiber (iNDF) of Alfalfa Hay and Corn Silage on Ruminal Degradability of Ration Fiber in Sheep

Two experiments were carried out to evaluate the effects of indigestible neutral detergent fiber (iNDF) of ration for estimation of rumen degradability of fiber in sheep. In experiment 1, to determine feed iNDF, four ruminal fistulated Zel ewes were used. Three grams of alfalfa hay, corn silage, barley grain, wheat bran, ration 1 (including alfalfa hay and concentrate), and ration 2 (including ...

critical period effects in foreign language learning:the influence of maturational state on the acquisition of reading,writing, and grammar in english as a foreign language

since the 1960s the age effects on learning both first and second language have been explored by many linguists and applied linguists (e.g lennerberg, 1967; schachter, 1996; long, 1990) and the existence of critical period for language acquisition was found to be a common ground of all these studies. in spite of some common findings, some issues about the impacts of age on acquiring a second or...

Inoculant effects on alfalfa silage: fermentation products and nutritive value.

The effect of 14 microbial inoculants on the fermentation and nutritive value of alfalfa silages was studied under laboratory conditions. The first cut (477 g of dry matter/kg) and second cut (393 g of dry matter/kg) of a second-year alfalfa stand were ensiled in 2 trials. In both trials alfalfa was harvested with standard field equipment. All inoculants were applied at 1.0 x 10(6) cfu/g of cro...
