1 ~ Data in Table 15-1 were compiled from commercial laboratories, literature data, Nutrient Requirements of Beef Cattle (National Research Council, 1996), and unpublished data provided by university researchers. When commercial laboratory data disagreed greatly with published data (~1.5 SD from the mean), the published data were used. The table includes means, standard deviations, and the number of samples (N) used to generate those statistics. Users should examine the standard deviation and N before using the mean value as an estimate of the nutritional content of a specific feed sample. Means derived from a large N will better reflect the total population. Means with a large standard deviation may represent the total population but may be a poor estimate for a specific sample. All energy values in Table 15-1 were calculated from the mean nutrient data for each entry. Values for ME and NED assume the diet has 74 percent TDN. Neutral detergent insoluble crude protein (NDICP) and acid deter- gent insoluble crude protein (ADICP) are not used directly to formulate diets but are used to calculate energy. Ether extract values represent the total lipid content of a feed but is a poor index of the true fat content of many feeds. The concentration of fatty acids in a feed is a measure of the true fat content and should replace the ether extract assay (Sukhija and Palmquist, 19881. Ether extract values were retained in this edition because of the limited avail- ability of fatty acid data for most feedstuffs. In some cases, data were used that were derived with different analytic techniques, especially neutral detergent fiber (NDF) because other data were not available (see section on Ana- lytic Procedures in chapter 131. Lignin and ash concentra- tions are used only to estimate energyvalues and the major- ity of lignin values were determined using sulfuric acid acid detergent lignin (ADL). Fiber concentrations are not presented for animal-based foodstuffs because the values have little meaning. Concentrations of macro and trace minerals are included in the table; however, before using these values, examine the standard deviations. Soil concen- trations of minerals are highly variable; geographic differ- Nutrient Composition of Feeds ences exist for the mineral concentrations of many feeds. For most trace minerals, the standard deviation is high. The use of mean values for copper, iron, manganese, sele- nium, and zinc is discouraged. Concentrations of molyEde- num are provided only in reference to copper availability. For a very limited number of entries, the concentrations of certain nutrients (NDICP, ADICP, and some minerals) were estimated. Values in the table with no N were esti- mated. Generally the estimates were from a larger popula- tion (e.g., the sulfur concentration for normal corn silage also was used for immature corn silage). For some hay crop forages, values for a specific maturity class were esti- mated from the all samples entries. For some forage classi- f~cations, estimates of NDICP and ADICP were calculated from the mean value as a percent of crude protein (CP) for the all sample entries and multiplying that value by the mean CP for the specific entry. Data for ground corn (dry and high moisture) was used for cracked dry and high moisture corn. Data for drv rolled sorghum was used for steam-flaked sorghum. J O Common names were used to designate feeds. In con- trast with previous editions, data for different species of cool season grasses (C-3) were combined into a single classification (Grasses, Cool Season). The classification was simplified because nutrient composition does not vary greatly among different species (Cherney et al., 19931. Similarly, common legumes (alfalfa, clover, trefoil) were combined into a single classification (Legumes, Forage). The standard maturity classifications were eliminated because data from commercial labs and published data often do not include specific maturity designations. Within the cool season grasses and forage legume categories entries were broken into low NDF, medium NDF, and high NDF. Typically less mature forages contain lower NDF concentrations, but growing conditions can alter that relationship. The NDF concentrations, included in each entry are in the table. Because of the widespread use of mixed legume and grass forages, entries were included for this type of forage. The difference in hemicellulose 281

282 Nutrient Requirements of Dairy Cattle concentrations between legumes and grasses was used to partition feeds into mostly (~70 percent) grass mixtures, mixtures with approximately equal amount grass and legume, and mostly (~70 percent) legume mixtures. Matu- rity classification for mixed forages was also based on NDF concentrations. Maturity of corn silage was estimated from dry matter content. Generally, as corn plants mature, dry matter increases (Wiersma et al., 19931. REFERENCES Cherney, D. J., J. H. Cherney, and R. F. Lucey. 1993.

Mineral element compositions of feed- grade sources vary by source, processing method, site of mining, and manufacturer. Sources should be analyzed or manufacturer's analyses should be used when available. Element composition of a source is listed if specific element concentration is 21.0%for macromineral elements, or 210,000 ma/ kg for micromineral elements, except for fluorine concentrations which are listed because of potential toxicity. a First digit denotes the class of feed: 1, dry forages and roughages; 2, pastured, range plants, and forages fed green; 3, silages; 4, energy feeds; 5, protein supplement; 6, minerals; 7, vitamins; 8, additives. The other five digits identify the individual feed. Dry matter contents have been estimated for the sources; actual analysis will be more accurate. Cfg = Feed-grade source. d None present. cop = Chemically pure form. fNA = Not available. g Use caution when handling and mixing; can be extremely hazardous. 6-00-370 6-09-338 6-01-082 6-05-586 6-01-080 6-01-780 6-03-945 6-03-707 6-03-947 97 97 97 99 97 100 100 75 100 2,100 70.9 2,500 2,100 5,550 1,800 1,800 35,000 3,100 15,000
