Quality in Roughages. I. Factors which Influence Hay Composition and Quality

Early-vegetative tall fescue hay vs alfalfa hay as a supplement for cattle consuming low-quality roughages.

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...

Alfalfa Hay Quality Testing

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....

Quality of Epidural Blockade. I. Influence of Physical Factors.

Varying concentrations of lignocaine between 1 and 5 per cent with and without adrenaline 1/200,000 were used for epidural analgesia in 255 patients. Measurements were made of latency of onset, degree of segmental spread, intensity of motor blockade and duration. The segmental spread of analgesia depended on the mass of solute injected and not on the volume, and at any given age the relationshi...

Factors Affecting Carcass Composition and Beef Quality

Protecting Hay Quality during Storage

When hay is first baled stored, it may go through a “sweat”, an increase in bale temperature. This increase in bale temperature is a combination of plant, bacteria, yeast, and fungi respiration. Plant soluble carbohydrates, principally sugars, are the source of energy for this respiration and increase in heat. As hay storage time increases, the hay loses Dry Matter (DM), and increases in Neutra...
