Increased herbage quality and estimated digestibility parameters like crude protein (CP), total digestible nutrients (TDN), digestible dry matter (DDM), digestible crude protein (DCP), dry matter intake (DMI), relative feed value
(RFV), relative forage quality (RFQ), net energy for lactation (NEL), digestible feed energy (DFE) and reduction in fibers were recorded with three 1.
Calculation of relative feed value, digestible dry matter, and dry matter intake
Relative feed value (RFV) is a widely accepted forage quality index in the marketing of hays in the United States of America.
On our farm, all dry matter for dry cows is haylage or dry hay of medium quality--120 relative feed value
Production costs of pounds 12-16/t are typical, and relative feed value
is now in excess of pounds 30/t prompting many to either grow beet, or have beet grown on their behalf this season.
Figure 4-5 Calculating relative feed value All values are given on a dry matter basis.
Another value that is often reported on a forage analysis is the relative feed value (RFV).
Neutral detergent fiber, acid detergent fiber, and relative feed value
of the forage is equivalent to those of 'Arrow.
Dry matter, fresh forage yield, plant height, dry matter content, panicle proportion, protein yield, lignin content and relative feed value
(RFV) tended to increase with advanced plant maturity, while leaf proportion, protein content, neutral detergent fiber content (NDF), acid detergent fiber content (ADF), cellulose content and hemicellulose content tended to decrease.
Relative feed value
(RFV) is a widely accepted forage quality index in the marketing of hays in the United States and has become a common tool for determining hay quality (intake and energy value).
Acid detergent fiber, neutral detergent fiber concentration, and relative feed value
Another feature is the ability to search for several different types of hay or bales, levels of relative feed value
, or in several different states or provinces, all at once.
