DM-Lancastor Fanning, Saturday, January 14, 1995 CONSULTANT CORNER/DAIRY TECH TALK A combination of nitrogen and protein sources are featured in high-energy Purina® Dairy products (Maxi-Tech® Super-EXT® and Ultimate EXT*). Result of studies at Purina Mills’ Dairy Research Unit indicate that rumen microbial activity is increased and digestibility of ration fiber components are improved when urea is added as a nitrogen source to fat-containing rations. Customers frequently ask, “Can we still use the protein and nitrogen sources in Ultimate EXT to obtain high production? We’re feeding high-quality alfalfa silage”. These managers have heard suggestions that “too much soluble protein” will result in rations of this type. Furthermore, some have been counseled that all rations which use high-quality alfalfa silage must have exotic protein sources added to the ration. Protein sources usually recommended with these opinions are blood meal, fish meal, and other animal by-products. Reasons for including these protein sources include: ’’too much soluble protein”; “not enough bypass protein”; or “blood urea nitrogen levels will be too high”. Seldom mentioned are the added expense of some of the protein sources or a potential lack of payability associated with these protein sources. Even with total mixed rations, palatability can be a problem when large amounts of some animal by-product protein sources are fed DETRICH ELEVATOR, INC. 5458 Cedar St Williamson, PA 17270 717-369-3724 Stevens Feed Mill Stevens, PA 717-336-2150 OLEY VALLEY FEED RD2 - Box 271 A Oley, PA 215-987-3568 KSy*llLS K K Paradise, PA 17562 717-442-4183 717-768-3301 Umonville, PA 19375 215-347-2377 EDDIE MORAN R D #1 Box 320 Jeffersonville, N Y. 12748 914-482-4199 UMBERGER’S MILL R D #4 - Box #545 Lebanon, PA 17042 717-867-5161 FRANKLIN FEED & SUPPLY 1977 Philadelphia Ave Chambersburg, PA 717-264-6148 as * Trademark of Ralston Purina Company PURINA MILLS, INC.

Details of the ration were: ° Ration Was: 60% Alfalfa Silage; 40% Grain (Dry Matter [DM] Basis) ° Alfalfa Silage Was; Dry Matter 45.9% DM Basis Crude Protein (CP) 20.2% DM Basis Acid Detergent Fiber 36.7% DM Basis Neutral Detergent Fiber 43.5% DM Basis Undegradable Intake Protein 22.4% Of Total CP 0 Production Trial During Weeks 4-17 Of Lacation ° Rations were: - Ration 1; Supplemental Protein Sources - Soybean Meal and Urea (Urea = 0.68% Ration DM). - Ration 2; Supplemental Protein Sources - Soybean Meal and Urea (Urea = 0.02% Ration DM). - Ration 3: Supplemental Protein Sources - Animal By-Products and Urea (Urea = 0.79%; Animal By-Products = 2.72% Ration DM). - Ration 4: Supplemental Protein Sources - Animal By-Products, Soybean Meal, and Urea (Urea = 0.10%; Animal By-Products = 3.15% Ration DM). - Ration 5: Supplemental Protein Sources - Animal By-Products and Urea (Urea = 0.40%; Animal By-Products = 4.86% Ration DM). - Ration 6: Supplemental Protein Sources - Animal By-Products, Soybean Meal, and Urea (Urea = 0.03%; Animal By-Products = 7.02% Ration DM). Key observations from this research are: ° Urea Intake Ranged Higher Than Typical Purina Program: - Minimum: 0.01 (Ration 2) and 0.02 (Ration 6) Lbs./Day. - Maximum: 0.39 (Ration 1) and 0.44 (Ration 3) Lbs./Day. ° Protein Source and Protein Degradability Had No Influence On Fat-Corrected Milk Production (See Figure) or Milk Components. ° Concentration of Plasma Urea Nitrogen Was Not Influenced By Protein Degradability or Protein Source. ° Addition of Animal By-Products To Ration In Amounts Ranging From 1.5 - 3.8 Lbs. DM / Day Decreased Total Dry Matter Intake By Up To 5.1 Lbs. (See Figure). Herd performance is often enhanced when Purina nutrient-dense supplements and superior forages, such as high-quality alfalfa silage, are combined in the feeding program. The sources of protein and nitrogen in Purina high-energy products can provide opportunities for additional production and profit, even if alfalfa silage is a staple forage source in your feeding program.
