The Claim
In cattle and goats, the concentration of beta-carotene in the liver increases with increasing dietary dose, reaching its highest level at 352 mg/kg dry matter.
What the research says
Supports is higher
Support is ahead, but a single strong opposing study can change this.
These are independent scores, not a percentage. Higher-grade studies count more, so a single strong opposing study can outweigh several weaker ones.
In cattle and goats, higher amounts of beta-carotene in the diet lead to higher levels of beta-carotene stored in the liver, with the highest storage occurring at a dose of 352 mg per kg of dry matter.
See the scientific wording
In both cattle and goats, the highest concentration of beta-carotene in the liver occurs at the highest dietary dose (352 mg/kg dry matter), indicating liver accumulation is dose-dependent.
When animals eat more beta-carotene, their intestines don't break it down completely, so more of it stays in the blood. The liver takes up this extra beta-carotene and stores it because it doesn't convert it into other molecules fast enough. When the amount eaten is high enough, the liver fills up and holds the most beta-carotene it can.
What the research says
1 studyWhen cows and goats eat more beta-carotene, their livers store more of it — and the most was stored when they ate the highest dose. This means the liver acts like a storage tank that fills up with more food.
