Recent surveys have estimated that the prevalence of hay fever among modem populations is between 2 and 15 per cent.1 Yet there are few references to the condition in any literature before the nineteenth century. Despite this fact, by 1900 hay fever was described as a common and fashionable disease. In this paper I outline the first descriptions of hay fever and how ideas about it developed thr...
In some areas of the country, producers store a substantial portion of their forage for winter feeding as silage or haylage. However, hay remains the most popular storage method for forage. Hay stores well for long periods and is better suited to cash sale and transportation than silage. Mechanical conditioning, which gained acceptance during the 1950's is probably still the greatest single cha...
A common question asked regarding feeding the performance horse is when should the horse be fed hay relative to grain and exercise. Should the horse receive hay before, with or after a grain meal. Research in our laboratory (Pagan et al, 1997) with resting horses showed that time of hay feeding affected glycemic response to a grain meal and total plasma protein (TPP) concentration. Increases in...
STUDY OBJECTIVES To examine the prevalence of asthma and hay fever, and the incidence and temporal relationships of asthma, hay fever, and chronic bronchitis among adult twins during a 15-year period. DESIGN Prospective cohort study. PARTICIPANTS A population of 11,540 Finnish adult men and women, initially 18 to 45 years of age, who returned a health questionnaire in 1975, 1981, and 1990 a...
The objective of this study was to evaluate nutrient composition, voluntary DMI, and apparent DM digestibility of teff hay cut at 3 different stages of maturity to evaluate its potential as a preserved forage for horses. Six mature Quarter Horse mares (12 +/- 3 yr; 553 +/- 39 kg of BW) were used in a replicated balanced Latin square design with 3 periods and 3 maturities of teff hay. Eragrostis...
Despite a shortage of animal feed in Iran, cereal stubble is often underutilized due to agro-economic reasons. On the other hand, lambs fed with a conventional fattening ration deposit a considerable amount of fat; therefore, this experiment was conducted aimed at better utilization of cereal stubble and reducing the fat content of lamb carcasses. Fat-tailed Mehraban and Ghezel ram lambs were p...
A feeding trial utilizing lactating dairy cows was conducted to compare Eastern gamagrass (Tripsacum dactyloides) and alfalfa hay. Response criteria included feed intake, weight change, and yield and composition of milk. Dry matter intake and milk yield of cows fed alfalfa hay exceeded that of those fed gamagrass hay. There was no significant difference in milk composition, and average weight c...
Gravid mosquito traps are commonly used for both arbovirus surveillance and population surveillance of mosquitoes of the genus Culex. Oviposition substrates, used as baits in these traps, were tested against Culex under laboratory and field conditions. In the laboratory all substrates tested as 1% and 10% dilutions in 2-choice bioassays against female Cx. quinquefasciatus were significantly mor...
Alfalfa is the most productive and highest quality forage species. Over one million acres of alfalfa have been harvested each year in Montana since 1960. Yield and forage quality of alfalfa vary widely across environments and operations. Currently there is much interest in targeting specialized hay markets. Most Montana producers can consistently produce alfalfa that is of fair to good quality....
Two hundred ninety-nine crossbred yearling steers (363 +/- 15 kg initial BW) were fed for an average of 114 d in a finishing study comparing 7 diets in which steam-flaked corn was used as the principal energy source. Forty-nine pens were used in this study with 7 BW blocks, 7 pens per treatment, and 5 to 7 steers per pen. A control diet with no distillers grains with solubles (DGS) was compared...
