The Claim
Cattle exhibit significantly lower 15,15'-dioxygenase enzyme activity in the duodenum and jejunum compared to goats, resulting in higher beta-carotene concentrations in adipose tissue and greater yellow pigmentation, despite similar dietary beta-carotene intake.
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.
Cattle have less enzyme activity in their small intestine than goats, leading to more beta-carotene stored in their fat and yellower fat color, even when both animals eat the same amount of beta-carotene.
See the scientific wording
Cattle exhibit significantly lower 15,15'-dioxygenase enzyme activity in the duodenum and jejunum compared to goats, resulting in higher beta-carotene concentrations in adipose tissue and greater yellow pigmentation, despite similar dietary beta-carotene intake.
In cattle, the enzyme that breaks down beta-carotene in the small intestine works much slower than in goats, so more beta-carotene stays intact and travels to fat tissue, where it builds up and turns the fat yellow.
What the research says
1 studyCattle have a weaker enzyme in their small intestine that breaks down beta-carotene, so more of it stays in their fat and turns it yellow. Goats have a stronger enzyme, so they break it down faster and don’t get as yellow.
