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...

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 ...

Two studies were conducted to evaluate high-quality tall fescue hay as a supplement to beef cattle fed low-quality roughages. In Exp. 1, 15 ruminally cannulated Hereford x Angus steers (average weight 390 kg) were blocked by weight and assigned randomly to one of three treatments: 1) tall fescue straw, no supplement; 2) tall fescue straw plus tall fescue hay supplement; 3) tall fescue straw plu...

The objectives of these experiments were to study the positive associative effects of supplementing barley straw-based diets with different levels of alfalfa hay on nutrient intake, rumen environment, and nutrient digestibility and to evaluate the minimal amount of alfalfa hay needed to produce such an effect in ewes. In experiment one, 15 Awassi ewes (®ve ruminally ®stulated; body weight ˆ 54 ...

Matua bromegrass hay (Bromus willdenowii Kunth) is a high quality forage, but its value for mares during gestation and lactation is not well known. Intake, rate of passage, performance, and reproduction by gestating and lactating Quarter Horse mares fed the hay was investigated. In this experiment, 12, 2- to 12-yr-old gravid mares (mean BW = 553 kg, SD = 36) were fed Matua hay (CP = 11.5%) or a...

this study was conducted to determine the chemical composition, digestibility, degradability and nutritive value of madder, rubia tinctorum l.  and alfalfa medicago sativa. using in vitro and in situ measurements. the mean values for om, cp, ndf, adf and ee were 892.5, 172.0, 306.5, 219.4 and 16.0 g/kg dm for madder hay, and 921.3, 141.4, 482.0, 361.1 and 6.50 g/kg dm for alfalfa hay, respectiv...

Five crossbred wethers (58 kg) fitted with cannulas in the rumen, duodenum, and ileum were used in a 5 x 5 Latin square design to study effects of feeding combinations of alkaline hydrogen peroxide-treated wheat straw (AHP-WS) and alfalfa hay at restricted intakes on site and extent of nutrient digestion. Additionally, flows and disappearance of N and amino acids (AA) in the small intestine wer...

Three experiments were conducted to compare soybean meal/sorghum grain (SBM/SG), alfalfa hay or dehydrated alfalfa pellets (DEHY) as supplemental protein sources for beef cattle grazing dormant range forage. In Exp. 1 (35-d digestion study), 16 ruminally cannulated steers were stratified by weight (average BW 259 kg) and assigned randomly within stratification to: 1) control, no supplement; 2) ...

OBJECTIVE This study was conducted to determine molecular structures related to carbohydrates and lipid in alfalfa hay cut at early bud, late bud and early flower and in the afternoon and next morning using Fourier transform infrared spectroscopy (FT/IR) and to determine their relationship with alfalfa hay nutrient profile and availability in ruminants. METHODS Chemical composition analysis, ...

BACKGROUND Feeding alfalfa hay is often recommended for its buffering components, like protein and calcium, to prevent lesions of the gastric mucosa in horses. Until now, there has been no information regarding the influence of alfalfa particle size on the gastric mucosa. The aim of this study was to investigate the effects of feeding two alfalfa preparations with different particle sizes (alfa...
