F1 Met Pack 30 – Provides two sources of methionine activity for increased milk yield, fat, and protein
What is F1 Met Pack 30?
In all dairy rations, there is a shortfall in the amount of methionine available compared to the methionine requirement.
F1 Met Pack 30 is the isopropyl ester of the hydroxy analogue of methionine (HMBi or HMTBi). It is available in both liquid and dry formulas.
An Excellent Source of Methionine
The reason that F1 Met Pack 30 works so well is:
- It provides HMBa (HMTBa) to the rumen microorganisms
- It provides an effective source of metabolizable methionine
Improved Milk Yield
You can expect an increase in overall milk yield after the introduction of F1 Met Pack 30, especially in early lactation.
Improved Milk Quality
F1 Met Pack 30 has been shown to improve levels of milk protein and butterfat.
Improved Health
Reduced instance of displaced abomasum, clinical & sub-clinical ketosis, mastitis & metritis.
Improved Reproductive Efficiency
Significantly reduces pregnancy losses.
50% Bioavailable, 50% Rumen Available
50% of F1 Met Pack 30 is absorbed through the rumen wall, hydrolyzed to HMBa (HMTBa), and is available as a metabolizable methionine source to the cow. The other 50% is available as HMBa for utilization in the rumen.
Methionine: More than Milk
Improves Milk Yield, Protein, and Fat
Summary of 6 trials (early lactation), conducted at INRA Rennes, INRA Nancy, University of New Hampshire and The Ohio State University. Average production 39 kg milk, 3.75% fat, 3.10% protein.
Improves Health
Supplemental methionine helps limit metabolic problems. This promotes peak milk, saves costs, and reduces early culling.
| Disease | Control | Methionine | Decrease % |
|---|---|---|---|
| Displaced Abomasum | 7/162 (4.3%) | 6/170 (3.5%) | 18 |
| Ketosis, Clinical & Subclinical** | 29/162 (17.9%) | 17/170 (10.0%) | 44 |
| Mastitis | 23/138 (16.7%) | 15/138 (10.9%) | 35 |
| Metritis | 16/138 (11.6%) | 9/137 (6.6%) | 43 |
More Pregnancies Maintained
Losses were reduced from 19% to 7% between pregnancy check #1 and #2*.
- Lower Average Days in Milk
- Less Re-breeding
- Less Culls
Meeting Methionine Requirements
Milk is just the tip of the iceberg!
| Energy Corrected Milk (ECM) Optimal ration concentrations of methionine and lysine maximize milk volume, protein and fat. |
 |
| More Than Milk |
|
| Liver Health Methionine plays a key role in the formation of VLDLs* to export fat out of the liver. |
|
| Protein Synthesis Methionine is the key amino acid needed to initiate protein synthesis. |
|
| Antioxidant Methionine is the precursor of taurine and glutathione, a very important antioxidant. |
|
| Epigenetics Methionine influences fetal programming through methylation of DNA. |
Six proven steps to successful amino acid balancing
By reaching the target concentrations for lysine and methionine, the daily metabolizable protein (MP) supply can be decreased by 100 to 150 grams.
This economizes on expensive rumen undegradable protein (RUP) and creates formulation space for other nutrients that can further enhance cow performance.
| 1: Feed a balanced ration that provides a blend of fermentable carbohydrates and physically effective fibre to optimize the yield of microbial protein and optimize rumen health. |
| 2: Feed adequate levels of Rumen Degradable Protein (RDP) to meet the rumen microbial needs for amino acids and ammonia. Do not feed excessive RDP. |
| 3: Minimize Rumen Undegradable Protein inclusion, as on average, RUP has lower concentrations of both lysine and methionine than microbial protein. |
| 4: Include high-lysine protein ingredients and a rumen protected lysine as needed to reach the target formulation level of lysine as a % of MP. |
| 5: Include a rumen protected methionine source to achieve the optimal ratio of lysine to methionine. |
| 6: Be sure the Plasma Free-Amino-Acid Dose Response Method has been used to validate the efficacy of the rumen protected sources of lysine and methionine used. |
