One hundred thirty-eight Angus cross yearling steers (initial BW 390 ± 0.5 kg) were allotted by BW to a 3 × 2 factorial arrangement of 6 treatments (4 pens per treatment) to determine the effect of wet distillers grains (WDG) concentration (0, 20, 40% of dietary DM) in low-forage (12% hay) and high-forage (50% hay) diets on growth performance and marbling. Steers were implanted on d 0 with Comp...

a case of tropical eosinophylia which seems to be an independent disease is described. the patient was admitted because of fever, loss of weight- ~and some respiratory disorders. the blood examination shows a high percentage of eosinophylia in several times. in this view other causes of the blood eosinophylia were eliminated by the laboratory tests. the patient was treated with arsenical drugs ...

Ammonia emissions and odor are being used to regulate animal produc­ tion. The objectives of this study were to observe the effects of restricted feeding dairy heifers high concentrate (HC) and low concentrate (LC) diets with different forage quality on NH3 emissions and odor. A split plot design with diet type as the whole plot and forage quality as sub­ plot was administered in a 4-period (21...

Selenium (Se) was applied to perennial ryegrass (Lolium perenne) and subterranean clover (Trifolium subterranean) pasture as a fertilizer to determine the effect of Se form and concentration on Se accumulation in subsequent forage growth. Treatments were a no Se control, 0.6 kg/ ha Se as sodium selenate, and 0.6, 1.1, and 2.2 kg/ha Se as sodium selenite, all applied to pasture plots with low so...

The role of the gastrointestinal tract (GIT) in explaining the less efficient utilization of metabolizable energy (ME) in growing lambs fed forage rather than concentrate-based diets was investigated by feeding forage (legume-grass silage) and concentrate (whole shelled maize) diets, at isoenergetic intakes (ME basis), using five groups of lambs. One group of seven lambs was an initial slaughte...

Suwarno, Wittenberg, K. M., Ingalls, J. R. and McCaughey, W. P. 2000. Performance of lactating dairy cows fed macerated forage conserved as silage and hay. Can. J. Anim. Sci. 80: 123–129. The effect of forage maceration at harvest on silage characteristics and its effect on lactation performance of Holstein cows were determined. Either a roller conditioner or a prototype forage macerator manufa...

BACKGROUND Current plant--herbivore interaction models and experiments with mammalian herbivores grazing plant monocultures show the superiority of a maximizing forage quality strategy (MFQ) over a maximizing intake strategy (MI). However, there is a lack of evidence whether grazers comply with the model predictions under field conditions. METHODOLOGY/FINDINGS We assessed diet selection of sh...

The concentration of NDF is heritable in several forage species, and rates of gain Voluntary intake is generally considered to be the single most from selection for reduced NDF concentration of herbimportant factor limiting animal performance on high-forage diets. Neutral detergent fiber (NDF) is the laboratory variable most closely age are reported to be as hi...

Forage age and maturity generally have a larger influence on forage quality than environmental factors. Plant environment, however, cause deviations in forage quality even when harvested at the same maturity. Temperature usually has greater influence on forage quality than other environmental factors. Although increasing temperature normally hastens maturity, the primary effect may be through i...

A control group of 6 rabbits (Group A) received forage from uncontaminated areas. Two other groups (B and C) of 6 and 8 rabbi ts, 'respectively, were fed forage grown near Chizzola exclusively. Seventy days after the beginning of the experiment, the S rabbits of Group C were given forage artificially polluted with material obtained from the purifying equipment of the factory after it had been t...
