How Seeds Can Boost Beef's Health Benefits

The idea of adding seeds to cattle feed is not new. It is known that seeds can change the fat content in beef. However, the impact of this change at different ages of the cattle has not been fully explored. A recent investigation looked into how feeding linseed to cattle affects their carcass traits, meat quality, and fat composition. The study involved 80 Simmental bulls. These bulls were divided into two groups. One group received a standard diet, while the other was given a diet enriched with about 1% whole linseed. The bulls were then slaughtered at either 13 or 17 months old. The researchers measured various factors, including carcass traits, meat quality, fat composition, and how well the meat resisted oxidation. Feeding linseed increased the dressing percentage of the bulls, regardless of their age at slaughter. This means that the bulls had a higher proportion of usable meat after slaughter.

However, linseed did not have a significant effect on overall carcass and meat quality. The fat within the muscle of linseed-fed bulls showed notable changes. It had less saturated fat and more beneficial omega-3 fatty acids, such as eicosapentaenoic and alpha-linolenic acid. These changes were more pronounced in the younger bulls. The study also found that the ratio of certain fats in the meat improved, but it did not reach the ideal levels. One concern was that the meat from linseed-fed and younger bulls was more prone to oxidation. This means the meat could spoil faster. So, while linseed supplementation can enhance the fat profile of beef, more work is needed. Higher levels of linseed, especially in older cattle, and additional antioxidant strategies might be necessary. This could help optimize both the stability and nutritional value of the meat.
