Net release of degraded N as NH3 and total AA plus microbial protein synthesis, quantified from incorporation of 15NH3 into microbial protein, was used to estimate the rate and extent of in vitro degradation of protein fractions isolated from alfalfa hay and silage. Seven proteins (casein, alfalfa hay, alfalfa silage, extracts from alfalfa hay and silage, and residues from alfalfa hay and silag...

Twenty Naieni breed replacement ewe lambs were used to determine the substitution effects of treated wheat straw with exogenous fiber-degrading enzymes for alfalfa hay on wool characteristics. Five treatment diets were included: 1) control (100% alfalfa hay without wheat straw), 2) 10% enzyme treated wheat straw replaced for alfalfa hay, 3) 20% enzyme treated wheat straw replaced for alfalfa ha...

this study was conducted to evaluate consumption inputs, production costs, nutrient composition and performance in production of alfalfa hay and alfalfa silage. therefore, data on alfalfa hay production were collected from 75 farms in zanjan province, using a face to face questionnaire in the year 2012. a systematic random sampling method was used. then, two farms managed by silage harvesting s...

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....

The key chemical analysis used to estimate the energy value of alfalfa hay for trading purposes, ADF (acid detergent fiber), has been supplanted by NDF (neutral detergent fiber) as the key chemical analysis used by nutritionists to evaluate the fibrosity and energy value of alfalfa hay for nutritional purposes. It is important that the alfalfa hay trading industry abandon ADF, as it will genera...

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...

Four insects species have emerged as important pests of alfalfa in the Western United States during the past decade. Cowpea aphid has long been a resident insect of the Western United States, but became a significant alfalfa pest during the past two years. The silverleaf whitefly has been a serious pest of alfalfa since 1991. Silverleaf whitefly reduces hay yield and contaminates alfalfa hay wi...

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...

OBJECTIVE To measure pH, volatile fatty acid (VFA) concentrations, and lactate concentrations in stomach contents and determine number and severity of gastric lesions in horses fed bromegrass hay and alfalfa hay-grain diets. ANIMALS Six 7-year-old horses. PROCEDURE A gastric cannula was inserted in each horse. Horses were fed each diet, using a randomized crossover design. Stomach contents ...

This experiment was carried out to study the effect of a directly fed exogenous fibrolytic enzyme on intake and digestion of DM, OM, protein, NDF, ADF, and hemicellulose of alfalfa and ryegrass hay by sheep. Four diets were randomly assigned to four ruminally cannulated lambs using a 4 x 4 Latin square design, repeated in time, with a factorial arrangement (2 x 2) of diets: 1) alfalfa hay; 2) a...
