108 Appendix Tables Description of Appendix Tables 4 to 6 Appendix Tables 4 through 6 present dietary protein levels (IPDM) above which added nonprotein nitrogen (NPN) sources such as urea should not be useful. Esti- mates are provided for various concentrations of die- tary energy (TDN) and of feed intake (TDNI or per- centage of body weight) and various degrees of ruminal proteolysis of dietary protein (DIPIP). Values for pro- tein use in the rumen for each species were calculated from regression equations that relate synthesis of micro- bial protein (BCP) to energy intake. Ruminal ammonia supply was calculated from extent of proteolysis (DIPIP) and recycling (RP). A maximum efficiency of 0.90 was used for ammonia capture by ruminal microbes. Utilization of ruminally degraded protein (DIP) was assumed to equal the synthesis of bacterial crude pro- tein (BCP) calculated from regression equations relat- ing bacterial protein yield to TDN intake for dairy cat- tle and for sheep as discussed in the chapter concerning microbial activities in the rumen. Values for BCP for beef cattle additionally considered the changes in effic- iency of microbial efficiency with level of roughage (assumed 55 percent TDN) and concentrate (assumed 90 percent TDN) in the diet and intake expressed as a percentage of body weight. Efficiency of conversion of DIP to BCP was assumed to be 0.90 though greater effi- ciency might be expected with lower ruminal ammonia concentrations. Recycling of nitrogen to the rumen (RP) was consid- ered to equal 0.15 TP for all species in these tables. For animals fed very low protein diets, RP might be more accurately predicted from dietary protein percentage rather than by assuming that only 15 percent of IP can be recycled. This is described in the text chapter. Further information concerning RP with various dietary concen trate levels and IPDM levels is needed] to more precisely predict dietary conclitions to which nonprotein nitrogen additions will be useful. Protein values in Appendix Tables 4, 5, and 6 indicate that urea can be added successfully to many diets for dairy cattle, beef cattle, and sheep. The level of IP at which urea addition is useful increases as extent of IP- resisting degradation in the rumen is increased (UIPIP) for all species. An increase in UIPIP decreases the amount of ammonia available for BCP synthesis so NPN can be included as a substitute source of ammonia. The level of IP at which urea addition is useful will increase as dietary TDN concentration increases for both cattle and sheep. This is a result of the increase in BCP synthesis that is driven by TDN concentration of the diet and feed intake. A similar relationship was not apparent in the values calculated for beef cattle. This was because efficiency of conversion of TDN to BCP dropper] as concentrate level increased so that urea use- fulness declined at the higher energy levels. Lower ef- ficiency of BCP synthesis at higher concentrate levels is apparent from data from other species as well, though few experiments with high concentrate levels for other species are available. Finally, TDN intake influenced urea usefulness for dairy cattle and sheep. Values changed because the re- gression equation for calculating BCP synthesis has an intercept value that is not zero. For beef cattle, urea usefulness also changed with feed intake level. This is a result of the influence of feed intake level on efficiency of BCP synthesis. Higher efficiencies of BCP synthesis have been reported at higher feed intal~e levels from a number of trials. As these estimates for urea utilization have been cal APPENDIX TABLE 4 Urea Usefulness with Various Feed Intakes, TDN Levels, and Ruminal Digestions of Dietary Protein Based on Equations from Dairy Cattle - Percent Dietary Protein Escaping Digestion in the Rumen 20 20 20 30 30 30 40 40 40 50 50 50 Dai 1 v TDN Intake ka. - _ . it, ~7 5 10 15 5 10 15 5 10 15 5 10 15 TDNX Percent Dietary Protein above which Urea is useless 55 7.94 9.22 9.65 8.87 10.31 10.78 10.06 11.68 12.22 11.60 13.48 14.10 60 8.66 10.06 10.52 9.68 11.24 11.76 10.97 12.74 13.33 12.66 14.70 15.38 65 9.38 10.90 11.40 10.49 12.18 12.74 11.89 13.80 14.44 13.71 15.93 16.66 70 10.10 11.74 12.28 11.29 13.12 13.72 12.80 14.86 15.55 14.77 17.15 17.95 75 10.83 12.57 13.16 12.10 14.05 14.70 13.71 15.93 16.66 15.82 18.38 19.23 80 11.55 13.41 14.03 12.91 14.99 15.68 14.63 16.99 17.77 16.88 19.60 20.51 . at al c u l ated as: ~ ( 26 .12*TDN I ) -31 . 86 )*6 . 25 ]/ ~ . 9* ( 115 -MU IP )*10* ( TDN I /TDNX ) where TONI is TDN intake, DIP is percent escape protein and TDNX is TDN percentage.

How- ever, these values should serve as guides to indicate the general conditions under which urea can be included in a diet as a substitute for other protein sources. If these values indicate that urea can be used, and if urea substi- tution for other protein sources will reduce feed cost, it should-be included in the diet. Description of Appendix Tables 7 and 8 Protein requirements for various types of growing- finishing beef cattle are presenter] in Appendix Tables 7 and 8. These were calculated from equations cited in various chapters and baser] on feed intakes and perfor- mance enumerated by NRC (1984~. A sample calcula- tion is provided below. A 300-kg (shrunk weight) medium-frame steer gain- ing at the rate of 1.2 kg (shrunk weight) daily requires 4.9 Meal of NEg. To consume enough feeds to achieve this intake of NEg, the diet must contain a minimum of 2.74 Meal metabolizable energy per kg of dry feed. This value was obtained by iterating feed intake and gain equations (NRC, 1984) at various ME levels. These iter- ated values for various rates of gain are provided in AN pendix Table 7. At the determined energy intake (7.2 kg of feed at 75.9 percent TDN), a typical feed would con- tain 59.7 percent concentrate and 40.3 percent forage if concentrate and forage were assumed to provide 55 and 90 percent TDN, respectively. (Actual values for roughage and concentrate could be used in the field.) With this feed intake level (7.2 kg per 300 kg body weight), this steer is consuming a total of 2.06 percent

From these values, efficiency of microbial protein (BCP) synthesis is 117 g BCP per kg TDN based on the equation: 6.25 * (8.63 + 14.6FI - 5.18FI * FI + 0.59 * CI). From the 7.2 kg of feed at 75.9 percent TDN, TDN intake is 5.47 kg. Total BCP synthesis in the rumen per day therefore is 641 g as shown in Table 12. Of this, 20 percent is nonprotein material, making true microbial protein (TBP) yield 512 g. At 80 percent di- gestibility, only 410 g become available as digestible bacterial protein (DBP). To determine how much die- tary protein is needed to supplement DBP to meet the protein requirement for this steer, protein require- ments must be estimated next. Metabolic fecal protein (FPN) loss was calculated as
Appendix Tables 111 0.09 indigestible dry matter. Indigestible ciry matter in this example is 1.73 kg (7.2 kg feed minus 5.47 kg TDN) so that F:PN equals 156 g. Endogenous urinary protein loss (UPN) at 2.75 W0 5 for this steer would be 48 g and surface losses (SPN) at 0.2 W0 6 would be 6 g. Conver- sion of available amino acids to FEN was assumed to be 100 percent, while conversion to UPN and SPN was esti- matec] to be 0.67. Hence, the inevitable protein loss would total 80 g.

Il2 Appendix Tables version of retained metabolizable protein (RPM) to retained net protein (RNP) of 0.50, 355 g of absorbed protein would be neerled here. The requirements for maintenance (80), fecal loss (156), and gain (355) total S91 g and must be supplied by intestinal digestion of either dietary or microbial protein. With a total need of 591 g and a supply of digestible true protein from ruminal microbes (DBP) of 410 g, the remaining deficit, which must be supplied as digestible dietary protein that has escaped ruminal fermentation (DUP), is 181 g. Assuming that such escape protein has a digestibility of 0.80, the supply of escape protein (IUP) must be 227 g as shown in Appendix Table 7. In addi- tion to this dietary protein need, a source of protein (or NPN) is needed for microbial protein synthesis. To syn thesize 641 g BCP, assuming a capture efficiency of 0.90, primarily due to ammonia loss with liquid flow- ing from the rumen, 712 g of ruminally cligested protein (RAP) is needed. Besides the supply from the diet, some protein is recycled to the rumen. Recycling by the re- gression equation suggests that 33 percent of IP would be available by recylcing leading to a very low (9.56 percent) protein requirement. Using the recycling value of IS percent of IF, as used for dairy cattle, the totaldietary protein needis(RAP + UIP)/l.lSor817g or as a percent of diet, 11.34 as shown in Appendix Ta- ble 8. Of the dietary protein, 227 ~ must escape ruminal ~, . _ fermentation. This is 28 percent of the dietary protein, also as shown in Appendix Table 8. Description of Appendix Tables 9 and 10 Appendix Table 9 presents a rigorous mathematical statement of the factors adopted for transforming feed protein into net protein for dairy cattle. A FORTRAN IV source program is used that includes the necessary input ant] output statements. Nearly every statement is documenter] with a comment statement. The energy re- quirement, net protein requirement for growth, and dry matter intake for growth are from the NRC (1978) requirements. The metabolic fecal protein equivalent, intake protein and metabolic transformations are those developed in this report. Examples are given for the 300-kg Holstein heifer gaining .7 kg/day and the 600-kg cow producing 30 kg of 3.5 percent milk/day. Appendix Table 10 presents a rigorous mathematical statement of the factors adopted for transforming feed protein into net protein for beef cattle. The rigorous mathematical statement is a working FORTRAN IV source program that includes the necessary input and output statements. Nearly every statement is docu- mented with a comment statement. The energy require- ment, net protein requirement, and dry matter intake are from the NRC (1984) requirements. The metabolic fecal protein equivalent, intake protein and metabolic transformations are those developed in this report. Ex- amples are given for the 300-kg medium-frame steer calf gaining 1.2 kg/day, the 500-kg cow that is 225 days pregnant and expected to produce a calf weighing 36 kg, and the 500-kg cow producing 10 kg of 4.0 percent milk/ day.
