The replacement of rumen-stable hardened fat by the linseed product Covalin FF leads to a higher milk yield and lower feed costs. This shows a practical trial on behalf of the manufacturer FeedValid. The difference can be calculated at 30 cents per cow per day.
This practical trial was carried out on a dairy farm in the Netherlands with 200 cows. At the beginning of the experiment, the daily milk yield was 31.5 kg with a feed ration enriched with hardened fat (0.3 kg / cow per day). For the experiment, this fat was replaced by Covalin FF (0.8 kg with 356 g fat / kg product). Since the linseed product Covalin FF contains not only fat but also protein and other nutrients, the feed ration was adjusted accordingly. As a result, the ration had the same feed value during the trial period as before the start of the trial; the feed costs dropped by 4 cents per animal per day.
After switching to feeding, the milk yield of the cows increased by an average of 0.5 kg with higher protein (+0.02) and fat (+0.05). This resulted in an additional milk revenue of 26.84 cents per cow per day. Taking into account the lower feed costs, we get a positive result of 30.84 cents. With 200 cows, this results in an increase of 22,513 euros over the year.
Covalin FF is a full fat linseed in which most of the unsaturated fats and proteins have been rendered rumen-stable by a special treatment.
"This trial shows that rumen-stable unsaturated fats are an excellent alternative to saturated fats," says Product Manager Dr.  Anke Schwitters of FeedValid. "In addition, linseed is rich in omega-3 and omega-6 fatty acids, which have a positive impact on the fertility and health of the animals and the quality of the milk fat."
