Thus, the E-Force improved the vitamin E status in the animal. The improved vitamin E status correlated with an improved immune system. This was observed in the decrease in some of the main stress indicators – see figure. HOW TO USE Administer 10 grams E-Force per head per day in the period from 3 weeks before weaning to 2 weeks after weaning. E-Force can also succesfully be used in other stressful periods. BENEFIT FOR THE FARMERS The improved vitamin E status and lower levels of stress indicators improve the health of the animals. • A new feed supplement for calves for use in the stressful period around weaning • Calves supplemented with E-Force during weaning had up to 51% higher plasma E values at weaning • The natural derived alfa-tocoferol is processed in a manner which prevents it from oxidizing • Higher absorption rate compared to other vitamin E products • Trials have shown a lower stress level in the calves Reference: Livestock Production Science, 253 (2021) 194672 VT220801 / Rev. 30.01.24 www.vilofoss.com info@vilofoss.com
