Feed additives manufacturers can compare the 3% and 5% starter layer premixes by inclusion designation, nutrient ranges, and ingredient group. Both are made for starter diets for young laying hens, but their nutrient values differ. Use the selected percentage in the complete-feed calculation before approving a purchase.

Vitamin, mineral, amino acid, calcium, phosphorus, salt, and water values
Listed ingredient group
Feed additives manufacturers supply starter premixes with different inclusion designations and nutrient concentrations. The 3% and 5% starter layer feed additives are intended for starter diets for young laying hens, and both list vitamins, minerals, amino acids, and supporting feed ingredients.
The two starter premixes at a glance
| Criterion | 3% starter layer feed additives | 5% starter layer feed additives |
|---|---|---|
| Product inclusion designation | 3% | 5% |
| Vitamin A (VA) per kg | 260,000-330,000 IU | 155,000-200,000 IU |
| Vitamin D3 (VD3) per kg | 100,000-160,000 IU | 40,000-100,000 IU |
| Vitamin E (VE) per kg | ≥ 1000 mg | ≥ 650 mg |
| Iron (Fe) per kg | 1-10 g | 0.6-6 g |
| Copper (Cu) per kg | 100-830 g | 0.06-0.5 g |
| Zinc (Zn) per kg | 1-4 g | 0.6-2.4 g |
| Manganese (Mn) per kg | 1-5 g | 0.6-3 g |
| DL-Methionine per kg | ≥ 2.8% | ≥ 1.3% |
| Calcium (Ca) per kg | 8-20% | 5-20% |
| Total phosphorus per kg | 1-3% | 1.5-6% |
| Sodium chloride (NaCl) per kg | 10-20% | 3.5-10.5% |
| Water per kg | ≤ 10% | ≤ 10% |
The profiles use different nutrient concentrations. Use each concentration with its stated inclusion designation when calculating the complete starter feed.
Inclusion designation and formula control
The 3% product is intended for a formula built around a 3% inclusion designation. The 5% product is intended for a formula built around 5%. Applying the wrong rate changes the amount of premix in the finished feed and changes its nutrient contribution.
Before purchasing, calculate the contribution of the selected additive from its per-kilogram values and the planned inclusion percentage. Check the result against the complete-feed recipe, including nutrients supplied by base ingredients and other components. This step is especially important where calcium, phosphorus, or sodium chloride already contributes to the ration.
Vitamin and mineral checkpoints
The 3% formulation lists VA at 260,000-330,000 IU per kg, VD3 at 100,000-160,000 IU, and VE at ≥ 1000 mg. The 5% formulation lists VA at 155,000-200,000 IU, VD3 at 40,000-100,000 IU, and VE at ≥ 650 mg.
For minerals, the 3% product lists iron at 1-10 g, copper at 100-830 g, zinc at 1-4 g, and manganese at 1-5 g per kg. The 5% product lists iron at 0.6-6 g, copper at 0.06-0.5 g, zinc at 0.6-2.4 g, and manganese at 0.6-3 g per kg. Keep the units unchanged in the formulation worksheet.
The amino acid line also differs: DL-Methionine is ≥ 2.8% in the 3% product and ≥ 1.3% in the 5% product. These values should be assessed with methionine and lysine supplied by the base ration.
Ingredient group and purchasing checks
Both products list methionine, lysine, dicalcium phosphate, phytase, calcium carbonate, sodium chloride, and fish meal among their ingredients. This gives you a common ingredient checklist for comparing the two options, while the nutrient values determine each product's contribution to the complete feed.
The calcium ranges are 8-20% for the 3% product and 5-20% for the 5% product. Total phosphorus is 1-3% for the 3% product and 1.5-6% for the 5% product. Sodium chloride is 10-20% and 3.5-10.5%, respectively. Water is ≤ 10% for both products.
Record the product designation, nutrient values, and complete-feed calculation on the same purchasing worksheet. Do not treat the 3% and 5% formulations as interchangeable simply because both are starter layer products.
Which option fits your feed plan?
Choose the 3% starter layer feed additive when your complete-feed formula is built around 3% and matches its nutrient profile, including VA at 260,000-330,000 IU, VD3 at 100,000-160,000 IU, and DL-Methionine at ≥ 2.8% per kg of additive. Choose the 5% starter layer feed additive when the formula is built around 5% and matches its profile, including total phosphorus at 1.5-6% and sodium chloride at 3.5-10.5%.
The percentage is a formulation input, not a stand-alone selection rule. Have your nutrition team assess the additive with the base ingredients and the complete starter diet for young laying hens.
The 3% starter layer feed additive suits buyers whose complete-feed formula is built around a 3% inclusion designation and its nutrient profile. The 5% starter layer feed additive suits buyers whose formula is built around 5% and its corresponding nutrient profile; select between them by checking the complete-feed calculation.

Questions to settle before ordering
How do the products differ in vitamin B12 content?
The 3% product lists vitamin B12 at ≥ 1 mg per kg, while the 5% product lists ≥ 0.45 mg per kg. Add this line to the vitamin review when you compare each premix with the complete starter diet. It helps prevent a formulation worksheet from covering the headline vitamins while overlooking a smaller-dose nutrient included in the product profile.
Which selenium range should appear on the comparison sheet?
The 3% product lists selenium at 4-16.5 mg per kg, and the 5% product lists 2-10 mg per kg. Keep the two ranges in separate columns because they are tied to different premix formulations. Use the selected product's value when checking the finished-feed calculation, including selenium contributed by other ration components.
What choline chloride values should procurement record?
Record ≥ 16 g per kg for the 3% product and ≥ 10 g per kg for the 5% product. Choline chloride is part of each product's listed nutrient profile, so it belongs on the same formulation worksheet as the vitamins and minerals. Keeping the two values separate supports a clean review when a buyer compares inclusion percentage and complete-feed contribution.
Make the percentage part of the purchase decision
The 3% option suits a starter formula built around the 3% inclusion designation and its nutrient profile. The 5% option suits a formula built around 5% and its corresponding values.
