The Bavarian Working Group Animal Nutrition (BAT) organizes its 61th annual conference this year at the LfL in Poing/Grub. The general topic is: “Successful young animal rearing for animal well-being and more sustainability”. Again, we were represented with a scientific contribution.
The title of our poster was: “Use of a rumen-stable combination of fat, lecithin and methionine in dairy cows in practice”.
The study results in brief:
In the study, the use of a rumen-stable combination of fat, lecithin and methionine was tested in practice in approx. 146 Holstein cows (BEWI-LACTO+® Leci-M).
- The use of 300 g of a rumen-stable combination of fat, lecithin and methionine (BEWI-LACTO+® Leci-M) significantly increased the daily milk yield by 1.34 kg; at the same time, milk fat synthesis decreased by 0.03 kg/day (p<0.13); milk protein synthesis was significantly increased by 0.08 kg/day (p<0.0001).
- The results indicate that at performances above 40 kg per cow per day, not only the selection of rumen-stable fat, but also the use of lecithin as a natural choline source in combination with rumen-stable methionine have positive effects. Positive effects on metabolic health are to be expected.
- The milk fat contents were higher due to the use of C16-rich rumen-stable fat, even if the milk quantity was lower compared to the use with BEWI-LACTO+® Leci-M. The daily amount of milk fat per cow and day showed no significant difference.
