Birdsfoot trefoil is a high-quality forage recommended for irrigated perennial pastures, either in mixtures with grasses or in pure stands. In this bulletin we report on the forage nutritive value of pure stands of birdsfoot trefoil harvested at 6week intervals, and compare it to alfalfa harvested at the same intervals. We found that the digestibility of the two forages was similar, but that al...

in this study, the performance of a fabricated fluffer was evaluated and compared with common field curing methods for alfalfa. the drying rate, baling loss and alfalfa nutrient value (dry matter and crude protein) were the criteria for evaluation. the alfalfa was cut using a mower-conditioner. a randomized complete block experimental design was used with three treatments (fluffing swathed alfa...

In order to determine of physical characteristics of rice straw as an effective source of fiber in ruminants, alfalfa hay, four varieties of rice straw (Taroum Neda, Taroum Neamat, Taroum Sangi, and Asgari), and four rations that contained four varieties of rice straws were investigated. The chemical (dry matter (DM), organic matter (OM), neutral detergent fiber (NDF), nonfiber carbohydrates (N...

Transgenic alfalfa over-expressing a nodule-enhanced malate dehydrogenase (neMDH) cDNA and untransformed alfalfa plants were grown at the same field site and rhizosphere soils collected after 53 weeks of plant growth. These alfalfa lines differ in the amount and composition of root organic acids produced and exuded into the rhizosphere. Nucleotide sequencing of PCR-based 16S ribosomal DNA (rDNA...

Alfalfa is one of the most important legume forage crops in the world. In spite of its agronomic and nutritive advantages, alfalfa has some limitations in the usage of pasture forage and hay supplement. High rapid degradation of protein in alfalfa poses a risk of rumen bloat to ruminants which could cause huge economic losses for farmers. Coupled with the relatively high lignin content, which i...

Six ruminally fistulated Hereford steers (body weight=414±13 kg) were used in a switch back design to determine whether two particle sizes of alfalfa hay (18.75 and 4.65 mm theoretical cut length) influenced salivary secretion during eating. The experiment carried out in two 26-d periods, with 11-d of adaptation to ration, followed by 5 d for determining the level of voluntary feed intake, 7-d ...

there are a little information about nutritive value of alfalfa harvested at different cuts and different cutting time (morning and afternoon) in semiarid climate condition of north east of iran. effects of different harvesting cuts and cutting time (6 a.m and 6 p.m) of alfalfa hay at early bud stage on chemical composition and in vitro gas production fermentation profiles were studied in this ...

Alfalfa was harvested as silage or hay and fed in two 12-wk trials with a 4 x 4 Latin square design that used 12 (trial 1) or 24 (trial 2) multiparous lactating cows (4 ruminally cannulated cows per trial). Diets contained (dry matter basis) 75 or 50% alfalfa plus 24 of 40% high moisture corn (trial 1) or 50% alfalfa, 44 or 41% high moisture corn, with (3%) or without fish meal (trial 2). Exper...

The potato leafhopper (PLH) is the most serious insect pest of alfalfa in Wisconsin and the Upper Midwest. PLH injury to alfalfa can result in leaf yellowing (“hopperburn”), plant stunting, loss of yield and forage quality, and reduced alfalfa stand persistence. Leafhopper populations are a perennial problem in new alfalfa seedings, and they frequently increase to damaging levels on the second ...
