four-handed fifty lactating holstein cows with mean body weight of, 597± 40 and 50±20 and days in milk body condi from sure of 3.1±0.4 were blocked by parity and randomly assigned to 3 treatments. each treatment had 3 pens and each pen had 50 cows. the experiment lasted for 60 days (10 days adaptation and 50 days collection period). concentrate to forage ratio was 60 to 40 and alfalfa hay repla...

Nutritional disorders associated with both forage and feed consump­ tion can have a large impact on the profitability of beef cattle operations. Forages are an important component of beef cattle production systems in Arkansas. Most cow­calf and stocker cattle enterprises in Arkansas rely heavily on forage­based nutritional programs. Forages are used for both livestock grazing and hay production...

Six mature geldings of light horse breeds (557 ± 37 kg) were randomly assigned to a nontoxic endophyte-infected tall fescue hay (n = 3) or pasture treatment (n = 3) in a crossover design with 14-d periods to estimate DMI with alkane markers and to compare DMI of hay and pasture. When fed pasture, horses were housed in stalls from 0700 to 1300 h daily with access to water and then grazed pasture...

BACKGROUND Asthma has been linked to stroke, but it is unknown if hay fever is related to stroke. This study was designed to investigate if there is an association between a reported history of hay fever and stroke during a 4.4-year study period. METHODS Analysis was performed of the Atherosclerosis Risk in Communities study, a cohort of middle aged and elderly adults. We examined the associa...

The disappearance of dry matter (DM), crude protein (CP), and amino acids (AA) in steers after rumen incubation and intestinal passage of alfalfa hay, barley hay, corn silage, barley grain, corn grain, wheat bran, meat meal, fish meal, cottonseed meal, and soybean meal were measured in 3 steers using a mobile nylon bag technique. Ruminal degradation of individual AA differed between feedstuffs....

Alfalfa hay was steam heated for an average of 47 min at 100 to 110°C; net ruminal protein escape (total escape minus ADIN x 6.25), estimated in vitro, was 50% versus 29% for control hay. Heating increased ADIN content from 4.6 to 15.3% of total N and increased NDF from 43 to 53% of DM. In trial 1, 14 cows averaging 81 DIM and 30 kg/d of milk were fed, in a switchback design, diets containing 1...

Forage quality has a large impact on market price and profitability. Nationwide, the marketing systems of Total Digestible Nutrients (TDN) and Relative Feed Value (RFV) are primarily ‘fiber-based’ marketing systems, since they depend upon Acid Detergent Fiber (ADF) and Neutral Detergent Fiber (NDF) lab measurements. Average change in California markets over 8 years of market reports in Californ...

a positive association between acetaminophen intake and allergic diseases has recently been reported in developed countries with impaired oxidant/antioxidant balance and promotion of atopy as proposed underlying mechanisms. the aim of the study was to explore the relationship between acetaminophen intake and asthma, hay fever, and eczema in the republic of macedonia as a country with acetaminop...
