Relative Feed Value Chart

Relative Feed Value Chart – Rfv= (ddm * dmi)/1.29, where rfv =. In samples from the worlds forage superbowl (see graph) show that rfv and rfq are highly correlated for alfalfa and with a similar mean (179 vs 177). While similar, understanding the unique differences of each is. Fodder nz relative feed value calculations based on sample data reported 5th may 2017:

Pdf | the aim of this study is to determine the relative feed value (rfv), relative forage quality (rfq) and net energy lactation (nel). Disregards the value of the remainder of the total digestible nutrients. Forage tests today contain two values summarizing feed quality. Relative feed value is calculated from feed analysis values.

Feeds can be analyzed in less than 15 minutes using nir, compared to hours. Select a representative 0.09 m2 (one square foot) area in the field (repeating this procedure on five to 10 plots across the field will give a good measure of the field's rfv). Relative feed value (rfv) and relative feed quality (rfq) are two values that you may see on a hay analysis that can help provide insight to the quality of the.

Dmi = dry matter intake (% of body weight) = 120 / (ndf, %dm) ddm. First, relative feed value is calculated using only fiber values. Rfv% = ddm% x dmi (% of body weight)/1.29:

Relative feed value is used for forages, and in particular, for alfalfa forages, including dry hay and haylages of predominantly alfalfa composition. Even though protein certainly affects the value of hay, it has absolutely no affect on the calculation of relative feed. Rfv is used to evaluate.

Purina animal nutrition reference document that provides expected ranges for % crude protein, acid detergent fiber, neutral detergent fiber, and relative feed value to support. However the range of rfq values at any rfv point is great (e.g. A combination of the two methods, by which the value of a feed could be determined no matter what its.
