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....

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...

It was confirmed in metabolic experiments with 4 individuals of roe deer (2 males and 2 females with the live weight of 20.8 and 17.9 kg, respectively) that due to the animals’ selective choice of a part of feeds there was no significant difference in the intake of lucerne hay of different quality and high-quality meadow hay (515.86 ± 66.97 and 597.82 ± 94.87 g, respectively). However, differen...

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...

a number of 36 holstein young bulls (initial bw of 345±61 kg) were randomly assigned to 6 dietary treatments, following a 3 × 2 factorial arrangement, with three concentrate levels of fish oil (0, 1.5 and 3 % of dm) and 2 levels of alfalfa hay versus corn silage (10 and 20 % of alfalfa hay forage versus 20 and 10 % of corn silage) were used to investigate the effect of fish oil supplementation ...

sixteen rams (mean age: 13 mo; mean live weight: 40.0 ± 2.4 kg) were randomly allotted to four dietary treatments in a completely randomized design (4 rams per treatment). diets (dry matter basis) contained 65% concentrate and 35% alfalfa hay (control diet, t1), 35% wheat straw (t2), 35% barley straw (t3) or 35% maize straw (t4). total-tract apparent digestibility for dry matter, organic matter...
