What's actually in Bil-Jac?
We analyzed Bil-Jac Adult Select, their core adult formula. The first five ingredients are chicken, chicken by-products, corn meal, ground corn, and chicken digest.
Chicken as the first ingredient sounds great — and it is a quality whole protein. But there's a catch. Whole chicken is about 70% water, so once it's cooked down, its actual contribution to the final kibble is much smaller than its #1 position implies. That means the real foundation of this food is what follows: by-products and corn. Two corn ingredients back-to-back (corn meal at #3 and ground corn at #4) is a textbook case of ingredient splitting — listing the same base ingredient under two names so each one appears lower on the list individually. Combined, corn is almost certainly the dominant ingredient by dry weight. Shop on Amazon →
The good stuff
The chelated minerals are the standout here. Zinc proteinate, iron proteinate, manganese proteinate, and copper proteinate are chelated (protein-bound) mineral forms that are significantly more bioavailable than the cheap oxide forms found in most foods at this price tier. You typically see this quality of mineral sourcing in B-tier and A-tier brands, so finding it in Bil-Jac is a genuine positive.
Brewers dried yeast is a natural source of B vitamins and can support skin and coat health. Dried egg product adds another animal protein source to the formula. And to Bil-Jac's credit, the ingredient list is relatively short and straightforward — there's no artificial colors, no BHA/BHT preservatives, and no mystery ingredients.
The not-so-good stuff
Chicken by-products at #2 is the first red flag. By-products can include organs, feet, necks, and intestines — essentially the parts left over after the meat is removed for human consumption. They're not inherently dangerous, but they're a lower-quality protein source than named muscle meat, and their nutritional value varies batch to batch.
The corn splitting is the bigger issue. When you combine corn meal and ground corn, this is fundamentally a corn-based dog food with chicken on top. Corn is a cheap carbohydrate filler with limited nutritional value for dogs compared to whole grains like brown rice or oatmeal. Chicken digest — a palatability spray made by chemically breaking down chicken tissues — suggests the base food doesn't taste appealing enough on its own. Soybean oil is a cheap fat source and a common allergen in dogs.
What's missing matters too. There's no dedicated omega-3 source (like fish oil or flaxseed), no fruits or vegetables of any kind, and no prebiotics or probiotics for digestive health. For a brand that markets itself as a premium choice, the formula reads more like a budget food with better minerals.
How it compares
Bil-Jac's C grade (59/100) lands it in the middle of the C tier, right between Iams (C/63) and Hill's Science Diet (C/61). It slightly edges out Iams thanks to those chelated minerals and whole chicken at #1, but it can't keep up with Purina Pro Plan (C/62) which at least includes fish oil for omega-3s.

For a food that positions itself as a step above the mainstream brands, the gap is surprisingly small. If you're willing to spend a bit more, Blue Buffalo (B/78) offers a meaningfully better ingredient profile with quality whole grains, flaxseed omega-3s, and no by-products or corn fillers.
The bottom line
Bil-Jac Adult Select earns a C grade (59/100) from KibbleIQ. The whole chicken and chelated minerals are legitimate positives, but the corn-heavy base, chicken by-products, lack of omega-3s, and zero fruits or vegetables keep it firmly in C territory. Bil-Jac has a loyal fanbase — many dogs genuinely love the taste — but loving the taste and being well-nourished aren't the same thing. If your dog is thriving on it, there's no emergency, but there are better options at similar or lower price points. Shop on Amazon →
