“…In the present study, supplementation of limiting amino acids improved F:G of G-F pigs (figure 3), but did not appear to make the NPN more useful to pigs or rats. Platter et al (1973) added amino acids to diets containing NPN and examined the effect on N retention in G-F pigs. A 10.9% protein opaque-2 cornsoybean meal diet supplemented with 3.1% protein equivalent from NPN (66% diammonium citrate, 6% monosodium glutamate and 28% glycine) was used as the control.…”

“…Feed intake, daily gain and N retention (as a percentage of intake) were all reduced by the additions of NPN. Platter et al (1973) also reported that the substitution of NPN (1.5% protein equivalent supplied by monoammonium phosphate) for soybean meal protein produced .no effect on body weight gains or feed consumption by pigs given either 12 or 15% protein diets. In a more definitive experiment, Platter et al (1973) added 3.1% protein equivalent from NPN to a 10.9% crude protein opaque-2 corn-soybean meal diet.…”

Ammonium polyphosphate (APP) was substituted for 0, 50 and 100% of the P supplied by defluorinated rock phosphate (DRP) in corn-soybean meal diets for growing rats and growing-finishing (G-F) pigs. The diets were formulated to contain 10% protein, .75% Ca and .60% P. Two-thirds of the P in the control diet was supplied by DRP. Replacement of 50 or 100% of the DRP with APP increased the dietary N by 7.25 and 14.5%, respectively. To evaluate nonprotein N (NPN) utilization, we used ammonium chloride (NH4Cl) to provide a level of N equivalent to that supplied by APP when it replaced 100% of the P supplied by DRP. These four treatments were repeated with supplementation of limiting amino acids (L-lysine, L-tryptophan and DL-methionine. Daily feed intake, rate of gain and feed:gain (F:G) of rats and G-F pigs were not influenced (P greater than .05) by the substitution of APP for DRP as a P source in corn-soybean meal diets with or without supplemental amino acids. F:G was improved (P less than .05) by the addition of limiting amino acids to diets for pigs, and a similar trend occurred in rats. The addition of NH4Cl to the 10% protein diets as a source of NPN resulted in no observable benefit for growing rats or G-F pigs. Percentages of ham and loin, percentages of bone ash and P content of the bone ash in pigs were not influenced by the dietary treatments.

“…Replacing crude protein in the diet with an equimolor mixture of diammoniura citrate and diammonium phosphate did not significantly depress performance of growing pigs until 20% or more of the crude protein equivalent was replaced(Wehrbein et al, 1970). However, in most cases, additions of nonprotein N did not affect growth(Platter et al, 1973; Zimmerman, 1975;Taylor et al,, 1981). Allen and Baker (1974) suggested that glycine, when supplemental levels are greater than 2% in chick diets, acts as an anorectic agent.…”

INFORMATION TO USERSThis reproduction was made from a copy of a document sent to us for microfilming. While the most advanced technology has been used to photograph and reproduce this document, the quality of the reproduction is heavily dependent upon the quality of the material submitted.The following explanation of techniques is provided to help clarify markings or notations which may appear on this reproduction. 1.The sign or "target" for pages apparently lacking from the document photographed is "Missing Page(s)". If it was possible to obtain the missing page(s) or section, they are spliced into the film along with adjacent pages. This may have necessitated cutting through an image and duplicating adjacent pages to assure complete continuity.2. When an image on the film is obliterated with a round black mark, it is an indication of either blurred copy because of movement during exposure, duplicate copy, or copyrighted materials that should not have been filmed. For blurred pages, a good image of the page can be found in the adjacent frame. If copyrighted materials were deleted^ a target note will appear listing the pages in the adjacent frame.3. When a map, drawing or chart, etc., is part of the material being photographed, a definite method of "sectioning" the material has been followed. It is customary to begin filming at the upper left hand comer of a large sheet an^d to continue from left to right in equal sections with small overlaps. If necess^py, sectioning is continued again-beginning below the first row and continuing on until complete. SUMMARY 36 APPENDIX 86 1 LITERATURE REVIEW Indispensable Amino Acid Requirements Based on innovative pioneer work. Rose (1938) classified arginine, histidine, isoleucine, leucine, lysine, methionine, phenylalanine, threonine, tryptophan and valine as indispensable amino acids for the rat. Rose defined an indispensable amino acid as one that cannot be synthesized in the body at a rate required for normal growth. The investigations with rats stimulated work with other species. Swine were found to require the same 10 amino acids for normal growth. The laboratories of J. K. Loosli at Cornell University (Bell, 1948; Brinegar, 1951) and W. M. Beeson at Purdue University (Beeson et al., 1948; Mertz et al., 1949; Shelton et al., 1950) were the first to conduct qualitative and preliminary quantitative amino acid requirement studies with pigs (Baker and Speer, 1983). Subsequently, Becker et al.(1963) estimated quantitative requirements of all indispensable amino acids for swine at various ages. For the weanling pig (13.6 kg), amino acid needs increased as protein level in the diet increased. His calculations were based on the assumption that the requirements for all amino acids, expressed as a percentage of the protein, decrease linearly as the dietary protein increases. However, NRC (1979) bases indispensable amino acid requirements on a constant percentage of the protein with advancing age and weight, because the amino acid concentrations in lean tissue remain the same and ma...
