The Claim
Grain feeding for six months in yaks reduces meat shear force from 18.98 to 11.05 kg/cm² and increases intramuscular fat content from 0.75 to 1.48 g/100 g, while increasing the n-6/n-3 PUFA ratio to 5.13.
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.
Feeding yaks grain for six months makes their meat more tender and fattier, but also increases the ratio of omega-6 to omega-3 fatty acids.
See the scientific wording
Grain feeding for six months in yaks significantly reduces meat shear force from 18.98 to 11.05 kg/cm² and increases intramuscular fat content from 0.75 to 1.48 g/100 g, indicating improved meat tenderness and fat deposition, though this is accompanied by a higher n-6/n-3 PUFA ratio of 5.13, which may reduce nutritional quality.
When yaks eat grain, their bodies get more energy and fats, which turn on genes that make fat cells inside the muscle grow bigger and store more fat. This extra fat softens the muscle by breaking up its tight structure, making the meat easier to cut. At the same time, the type of fat changes to include more unhealthy fats and fewer healthy ones.
What the research says
1 studyFeeding yaks grain instead of grass for six months made their meat softer and fattier, just like the claim says—but it also increased fats that are less healthy for humans.
