Feed Wise considers this a workable everyday option for Horizon Pet Nutrition Legacy Slim & Vibrant, an extruded kibble formula. The manufacturer publishes a nutritional adequacy statement, so it can be fed as a complete daily diet for all life stages. Owners should note that portions shown here are calculated from the calorie panel rather than a published chart.

1. CHICKEN
Tier A, exceptional food ingredient
Named Animal Protein
Named animal muscle meat. Highest value protein source in the FeedWise model.
2. CHICKEN MEAL
Tier B, high quality supportive ingredient
Named Rendered Protein
Named rendered animal meal. Concentrated named animal protein, but rendered rather than whole.
3. RED LENTILS
Tier C, moderate or neutral ingredient
Whole Carbohydrate
Whole carbohydrate source. Evaluated on position, quantity and combined plant load rather than treated as automatically poor.
4. PEA FLOUR
Tier D, lower value formulation ingredient
Refined Plant Fraction
Refined or fractionated plant ingredient. Lowers ingredient quality when used prominently.
5. GARBANZO BEANS
Tier C, moderate or neutral ingredient
Whole Carbohydrate
Whole chickpea. A pulse carbohydrate and plant protein source.
This is the largest single category in FeedWise. It looks at which animal ingredients are present, whether the species is named, whether organs, egg and named fats are included, and whether concentrated plant proteins are diluting the animal content.
Named animal protein first
CHICKEN is a named animal ingredient in position 1.
Animal Prominence Index
Animal Prominence Index 52 of 100. This is a FeedWise position-weighted measure of how far animal ingredients dominate the ingredient panel. It is a label-position index, not a manufacturer-disclosed recipe percentage.
Liver
No liver in the ingredient panel.
Heart
No heart in the ingredient panel.
Other appropriate organs
No additional organ meats identified.
Whole egg
EGG PRODUCT is included.
Named animal or marine fats
Named animal or marine fat sources: CHICKEN FAT (PRESERVED WITH MIXED TOCOPHEROLS, A SOURCE OF VITAMIN E).
Verified animal ingredient proportion
The manufacturer has not published an animal ingredient percentage. Excluded from the score rather than counted against the product.
Plant protein dilution
No concentrated plant proteins detected.
Every ingredient is classified into a quality tier and weighted by its position on the label, so ingredient number one counts far more than ingredient number fifteen.
Position weighted ingredient quality
17 food ingredients assessed by quality tier with early positions weighted most heavily. 38 fortifying nutrients or preservatives excluded from the average.
Estimated carbohydrate, calculated as 100 minus protein, fat, moisture, fibre and ash.
Carbohydrate burden
Calculated with a published ash value carbohydrate of 37.1 percent.
Ingredient based plant load
Plant load assessed as VERY HIGH. Carbohydrate bearing plant ingredients: RED LENTILS (whole pulse), PEA FLOUR (refined starch), GARBANZO BEANS (whole pulse).
Combined pulse load
3 pulse ingredients detected at positions 3, 4, 5: RED LENTILS, PEA FLOUR, GARBANZO BEANS. Together these represent a substantial plant contribution.
Processing method: Extruded. This category measures food integrity only. Raw handling safety is assessed separately under Safety and Quality Control, so a raw food can score well here and still lose safety points.
