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,
payability can be a problem when large amounts of
some animal by-product protein sources are fed

Research With Alfalfa Silage
Researchers at the University of Wisconsin supplemented an alfalfa silage ration
with grain and various protein supplements to investigate production responses.
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.
