Alfalfa hay is, or should, be highly valued as a dairy cattle feed due to its relatively high (for a forage) crude protein (CP) level which has a low rumen soluble fraction and a relatively high rumen escape fraction which contains a high level of the key amino acid lysine. It should also be valued for its high level of rapidly rumen digested pectin which has a high cation exchange capacity (CE...

Roundup-Ready® alfalfa was released in June of 2005, the first trait to be commercialized in alfalfa (Medicago sativa L.) using biotechnology. Traditional alfalfa varieties will likely be grown in close proximity to these new biotech varieties. While most users will probably not be sensitive to the presence of these varieties, other markets (particularly export and organic) will request hay tha...

this study was conducted to determine nutritive value of common animal feed sources in east azerbaijan province including second cutting of alfalfa hay ( n=35) and wheat straw (n=26). chemical composition and mineral contents of alfalfa hay and wheat straw were determined according to standard methods. then the average chemical compositions of these samples were compared with those of the gilan...

Selenium (Se) is an essential trace mineral important for immune function and overall health of cattle. The nasopharyngeal microbiota in cattle plays an important role in overall respiratory health, especially when stresses associated with weaning, transport, and adaptation to a feedlot affect the normal respiratory defenses. Recent evidence suggests that cattle diagnosed with bovine respirator...

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 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...

Two experiments were conducted to evaluate the effect of feeding legume hay (alfalfa; Medicago sativa L.) or mixed-grass hay on ADG and carcass characteristics of growing goats. In Experiment 1, 24 Spanish kids, equally representing female, intact male and wether goats, were pen-fed ad libitum either chopped alfalfa (16.8 percent CP) or mixed grass hay (9.4 percent CP) (3 pens/diet) and a corn/...

limited data exist about the production of extruded linseed as a feed ingredient in farm animal nutrition. the objective of this study was to produce and evaluate extruded linseed mixed with alfalfa hay, pistachio by-products, and sugar beet pulp or corn grain in different proportions of linseed: alfalfa hay: pistachio by-products at ratios of 70:15:15, 70:20:10, 70:10:20, and 80:10:10 for qual...

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....
