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, payability can be a problem when large amounts of some animal by-product protein sources are fed OLEY VALLEY FEED RD2 - Box 271 A Oley, PA 610-987-3^68 KSV^ILLS Paradise, PA 17562 717-442-4183 1-800-635-3592 Umonville, PA 19375 610-347-2377 EDDIE MORAN R.D #1 Box 761 Jeffersonville, N.Y, 12748 914-482-5302 UMBERGER’S MILL R D #4 - Box #545 Lebanon, PA 17042 717-867-5161 58 FRANKLIN FEED & SUPPLY K 1977 Philadelphia Ave Chambersburg, PA 717-264-6148 K X X STEVENS FEED MILL NISSLEY FEED CENTER v s ste?eSs E PA H.C.

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 thls> research are: 0 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. 0 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 0 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.
