Zoologic® 42/25 (Milk Matrix 42/25) is a high-protein, low-lactose powdered milk replacer and supplement designed for the hand-rearing and nutritional support of wild and exotic mammals. Formulated as part of PetAg’s Milk Matrix system, it allows rehabilitators and caregivers to closely match the natural milk composition of a wide range of species.
With a 42% protein and 25% fat guaranteed analysis, this formula provides rich, balanced nutrition to support growth, development, and recovery in orphaned or supplemented animals.
Designed for Flexible, Species-Specific Nutrition
Zoologic® 42/25 can be used on its own or blended with other Milk Matrix products to create customized formulas tailored to individual species’ needs. This flexibility makes it a trusted option for wildlife rehabilitators working with mammals such as bears, raccoons, felines, and other exotic or non-domestic species.
High Protein, Balanced Fat
Formulated with 42% protein and 25% fat to support healthy growth and tissue development in species requiring nutrient-dense milk.
Low Lactose Formula
Contains minimal lactose, making it suitable for many non-domestic mammals that are lactose-sensitive.
Milk Matrix Compatibility
Part of PetAg’s Milk Matrix system, allowing it to be blended with other Matrix formulas to better replicate natural maternal milk.
Fortified for Growth & Health
Includes essential vitamins and minerals to support proper development, immune health, and overall wellbeing.
Easy to Mix & Use
Smooth, consistent powder mixes easily for reliable preparation during hand-feeding or supplemental feeding.
Reconstituting milk replacers with water is most accurately accomplished by weighing the individual components. If weighing is not possible, use the following volume measurements to reconstitute Milk Matrix 42/25 powder to the indicated approximate concentrations.
| Powder | Water | % Solids | % Protein | % Fat | % Lactose |
|---|---|---|---|---|---|
| 1 Part | 1 Part | 30.5 | 12.8 | 7.6 | 3.7 |
| 3 Parts | 4 Parts | 24.8 | 10.4 | 6.2 | 3.0 |
| 2 Parts | 3 Parts | 22.7 | 9.5 | 5.7 | 2.8 |
| 1 Part | 2 Parts | 18.0 | 7.6 | 4.5 | 2.2 |

One part is a volume measurement such as a tablespoon or cup. The volume relationships shown above were calculated from the following weight-volume measurements. All weights were made on level measurements:
| Utensils | Milk Matrix 33/40 Powder Weight | Water Weight |
|---|---|---|
| 1 Tablespoon | 6.5g (28 kcal) | 14.8g |
| 1 Cup | 104.0g (527 kcal) | 236.6g |
Suggested Powder : Water Mixing Ratios for Various Species
Directions for Use: As a milk replacer Milk Matrix 33/40 may be used alone or blended with other products in the Matrix family to formulate a milk replacer with nutrient levels that closely match a species’ natural milk.
Directions for Feeding: As a general rule, liquid or reconstituted milk replacer should be fed at a rate of 10% or 20% of body weight daily as tolerated or required for steady growth and for proper stool condition. Divide the total daily amount into 6 to 12 feedings per day, depending on age, condition, species and staffing.
Weaning Food Supplement: Because of its highly digestible milk nutrients, the formula used during suckling is an excellent supplement during weaning as a transition from milk to solid food. Add to the diet at the rate of one teaspoon per 10 pounds of body weight.
Store unopened powder in a cool dry place. Reconstituted powder must be kept refrigerated for up to 24 hours. Blended or unblended opened powder can be refrigerated for up to 3 months, or can be frozen for up to 6 months. Unopened powder may be frozen to extend shelf life for 6 months beyond best by date.
