	Green Gold Program Top Quality Forage - Manitoba Agriculture and Food
		The decline in RFV was most rapid in the early part of the sampling period.
		For producers wanting to target 150 RFV (by cutting at 165 RFV), the optimum cutting dates were June 14 in 1995, June 12 in 1996, June 14 in 1997, June 16 in 1998 and June 14 in 1999.
		RFV is a calculated figure based on lab analysis for two types of fibre levels in the plant -- acid detergent fibre (ADF) which provides an indication of forage digestibility, and neutral detergent fibre (NDF) which provides an indication of potential daily forage dry matter intake.

	Tests Available for Measuring Forage Quality
		To calculate RFV it is necessary to have a forage analysis for acid detergent fiber (ADF) and neutral detergent fiber (NDF).
		RFV is calculated by multiplying digestible dry matter by dry matter intake and then dividing by 1.29 (the expected digestible dry matter intake as % of body weight for full-bloom alfalfa).
		When using RFV or RFQ, it is best to compare hays that are within a similar classification such as alfalfa, grass, or mixed.

	Cattle Today: DEVELOPING A SOUND FORAGE ANALYSES A PROGRAM Part 2
		The number derived from the RFV calculation has no units and is used only as an index to compare different quality hays and/or haylages.
		In other words, the higher the RFV of a forage sample the more digestible it is and the more an animal can eat.
		Interestingly, based in the RFV system as well as the crude protein content, if a producer is required to buy hay, it is often a better value for him to spend more per ton and purchase a better quality hay, such as alfalfa, than to spend a bit less and buy some grass hays.

		Nonetheless, they must be specified since the RFV is expecting to have to manipulate stimuli at some point (after all, that is the main purpose of the program).
		When we run the RFV with the example input file, the setup window should appear looking similar to the one in Figure 7.
		If we again run the RFV with the latest additions to the input file, the first thing that you should notice is that the block defined in ``Component 1'' looks the same as it did last time.

		Amidst all the possible ways to measure forage quality, the RFV index has provided a reliable means to objectively quantify forage quality of alfalfa, and thus add some objectivity to determining a market value.
		While RFV has been very valuable for marketing alfalfa hay, it has not been as useful or reliable as would be desirable in predicting livestock performance and/or building rations, especially for grasses and corn silage.
		RFV is based on the concept of potential digestible dry matter intake of a forage by the animal.

		Relative feed value (RFV) is an index that reflects the fiber fractions, which dictate potential digestible dry matter feed intake.
		The higher the RFV, the higher quality feed value is obtained from the forage.
		RFV ranks forages relative to the digestible dry matter intake of full bloom alfalfa (RFV of 100, ADF of 41, and NDF of 53).

		In order to achieve a 150 RFV to the cow, it is recommended to harvest the first cutting when the RFV reaches 170 in the field.
		Using the RFV as a first cutting harvest guide is preferable to the âcutting by the calendarâ method often used by producers.
		The average decline in RFV for the two fields harvested in Clinton County was 18.4 points as shown in Table 4.

	Legumes - Spraying For Alfalfa Weevils Increases 1st Cutting RFV
		Surprisingly, the RFV of the "damaged" or unsprayed alfalfa was still good at 132 points as determined using near infrared reflectance spectroscopy (NIRS).
		In addition to RFV, spraying was also found to improve dry matter tonnage by an average of 0.06 ton per acre, or $3.90 per acre assuming an alfalfa market value of $65 per ton.
		The total benefit of spraying alfalfa weevils (at initial field population of 200 larvae per 10-sweeps-of-an-insect-net) in terms of RFV, CP, and tonnage was $20.09 per acre ($11.29 + $3.90 + $4.90 per acre).

		One of the limitations of the RFV system is that it assumes constant relationships between NDF and intake and between ADF and digestibility (Figure 1).
		This has often resulted in the RFV of high quality grasses being underestimated because their intake is underestimated.
		However, the RFQ and RFV of individual samples varied by as much as 40 points and 22% of the samples varied by 20 points or over.

	Standing Crop Quality of Alfalfa Prediction Model - Manitoba Agriculture, Food and Rural Initiatives
		After selecting an RFV target based on the intended market or class of livestock to which the forage will be fed, the prediction model can be used to select the optimum timing of forage cutting.
		As a general rule of thumb, alfalfa should be cut when it reaches a standing crop RFV 20 points higher than the RFV target.
		For producers who have precise RFV targets, it is recommended that alternative methods of measuring standing crop quality (scissor clipped NIR or wet chem analysis and PEAQ) be used in addition to the RFV model.

		RFV (Relative Feed Value) is nothing more than a single number designed to help understand ADF (Acid Detergent Fiber) and NDF (Neutral Detergent Fiber).
		If a dairy uses only one source of hay at a time, hay with RFV = 200 is not worth more than hay with RFV = 170.
		A dairy that uses several sources of hay may mix very high RFV hays with hays that are only mediocre.

		If the most mature stem in the 2-square foot sampling area is in the bloom stage, use the pink/magenta ("bloom") side of the PEAQ stick to estimate RFV using the tallest stem in the sampling area (which may not be in the bloom stage).
		Note that even though this tallest stem was vegetative, the pink/magenta (bloom) side of the PEAQ stick was used to estimate RFV because the most mature stem in the sampling area was in bloom stage.

		In order to reach 150 RFV, producers must cut the crop at 165 RFV because one can expect to lose about 15 points during harvest due to leaf loss and continued respiration.
		The RFV is determined by a lab analysis that compares the acid detergent fibre (ADF) that indicates the forage digestibility, and neutral detergent fibre (NDF) that provides an indication of potential daily forage dry matter intake.
		RFV has become an industry standard for measurement with 150 RFV being optimal.

		Relative Feed Value (RFV) attempts to use a single value to describe forage quality, and has become a common tool for determining hay quality (intake and energy value) and in pricing hay.
		Relative Feed Values have been developed for alfalfa, but because fibre characteristics differ among forage species, RFV cannot be used to compare grass or grass-alfalfa hay to alfalfa.
		For example, if the desired RFV of the baled feed is 150, harvest should occur at 170.
