G84-693 Protein Levels For Growing And Finishing Cattle, Rick Stock, Terry L. Mader, Terry Klopfenstein Jan 1984

G84-693 Protein Levels For Growing And Finishing Cattle, Rick Stock, Terry L. Mader, Terry Klopfenstein

University of Nebraska-Lincoln Extension: Historical Materials

This NebGuide describes the use of nonprotein nitrogen and bypass protein sources to fulfill the protein requirements of growing and finishing steers, heifers and bulls. Protein supplementation can be an expensive feed cost for cattle producers. Through the use of nonprotein nitrogen (NPN) and bypass protein sources, however, these costs can be reduced. Bypass protein is the protein that escapes breakdown in the rumen and passes "as is" into the small intestine where it is digested and absorbed. Because NPN sources are usually the most economical sources of supplemental nitrogen, NPN should be used whenever possible. The potential for using …


G84-737 Soybean Inoculation -- When Is It Necessary?, Roger Wesley Elmore Jan 1984

G84-737 Soybean Inoculation -- When Is It Necessary?, Roger Wesley Elmore

University of Nebraska-Lincoln Extension: Historical Materials

This NebGuide discusses when soybean seed should be inoculated and why, and provides recommendations on inoculant types to use. Soybeans can obtain up to half of their nitrogen needs from the air when nitrogen-fixing rhizobia bacteria are present in the soil. Nitrogen fixation is a result of the symbiotic (beneficial to both) relationship of rhizobia and plants. Establishing rhizobia (inoculation) in a field that has never grown soybeans is needed to insure nitrogen fixation. Reinoculation may be necessary in fields with a past history of soybeans.


G84-694 New Protein Values For Ingredients Used In Growing Cattle Rations, Rick Stock, Terry L. Mader, Terry Klopfenstein Jan 1984

G84-694 New Protein Values For Ingredients Used In Growing Cattle Rations, Rick Stock, Terry L. Mader, Terry Klopfenstein

University of Nebraska-Lincoln Extension: Historical Materials

This NebGuide assigns new protein values to feeds and describes two new systems for evaluating supplemental protein sources. Information about protein sources has changed greatly in the last 10 years. Words like "bypass," "escape," or "slowly degraded" have been used to describe some proteins. These terms have the same meaning and refer to a protein source's ability to escape breakdown in the rumen. Ingredient tables usually only list the crude protein content of feeds. Although this has been a useful system, it does not adequately evaluate supplemental protein sources. Digestible protein values have helped describe some forages, but can be …
