Study shows marine omega-3 fatty acids have positive effect on muscle mass

...in order to find an alternative to hormonal growth stimulation in beef cattle. At 4 to 6 months of age, calves become less efficient at converting food into muscle mass, which has a negative impact on farming profitability.
