in the last. Bermuda hay made up a large part of the total dry matter intake during the last 47 days of the trial. Daily intake of protein should have been very adequate in the early part of the test, but would have declined to marginal levels during the last 56 days due to the weather related failure to grow green forage. The overall response to providing 200 mg. of monensin to cattle grazing ...

the objective of this research was to study the effects of phenological stages on yield and quality traits in 22 populations of tall wheatgrass agropyron elongatum. a split plot design was conducted using a complete randomized block with two replications in lorestan (borujerd), iran during 2007-2008. the genotypes were cut in five maturity stages as vegetation, stem elongation, heading date, an...

Net release of degraded N as NH3 and total AA plus microbial protein synthesis, quantified from incorporation of 15NH3 into microbial protein, was used to estimate the rate and extent of in vitro degradation of protein fractions isolated from alfalfa hay and silage. Seven proteins (casein, alfalfa hay, alfalfa silage, extracts from alfalfa hay and silage, and residues from alfalfa hay and silag...

Dietary selenium influences the Se content in edible muscle of beef cattle. Limited data are available to describe the effects that feeds naturally high in Se have on production, carcass characteristics, and Se distribution in terminal tissues. Therefore, 43 crossbred steers (BW = 351 +/- 24 kg) were stratified by BW and assigned to one of four dietary treatments: Se adequate (CON; n = 12), Se ...

Three experiments were carried out to study the effects of feeding lucerne silage (wilted to give different drymatter (DM) contents) and ventilated hay to dairy cows on milk production, milk quality, milk-renneting properties, clostridial spore content and the quality of cheese prepared from the milk. The lucerne, cut at vegetative or early-bud stages of maturity, was harvested from alternate w...

The objective of this research was to study the effects of phenological stages on yield and quality traits in 22 populations of tall wheatgrass Agropyron elongatum. A split plot design was conducted using a complete randomized block with two replications in Lorestan (Borujerd), Iran during 2007-2008. The genotypes were cut in five maturity stages as vegetation, stem elongation, heading date, an...

This study was carried out to compare in situ and in vitro enzyme techniques for determining estimates of forage escape proteins. Eight forages (vetch hay, wheat silage, corn silage, wheat hay, grass hay, lentil straw, triticale hay and alfalfa hay) were used as feed materials. During 70 h, incubation with enzyme method had similar escape protein values for vetch hay, wheat hay, grass hay, trit...

     Effect of drying method was investigated on chemical composition, nutrient digestibility and rumen fermentation parameters of alfalfa hay harvested in the morning or afternoon. Experimental treatments consisted of alfalfa harvested in the morning and dried in sun, alfalfa harvested in the afternoon and dried in sun, alfalfa harvested in the morning and dried in shadow, alfalfa harvested in...

Six ruminally cannulated steers were used to determine the effects of altering dietary concentrates on fiber digestion. Diets contained 30, 60 or 90% of a concentrate based on flaked sorghum grain plus a 50:50 mixture of wheat straw and alfalfa hay. Total tract digestibility of NDF was not altered, but digestibility of potentially digested NDF (PDF) decreased (P less than .05) from 92 to 48% as...
