It is first used in Europe and Canada with short growing season. At present, 20% of the forage silage in European countries adopts the winding film method, which reaches 40% in Sweden. In Europe and North America, the annual growth rate of the grass winding film reaches 15%.

Advantages of forage film:

1. Controlled anaerobic fermentation to produce high nutrient feed

2. High concentration and easy digestion

3. Fast weight gain of animals

4. High milk yield, high milk fat content

5. Reduce losses caused by deterioration and nutrient loss

6. Long storage life -- reduce pH value and increase stable growth

7. Especially important in areas with short growing season

8. Reduce climate risk during harvest

9. Hay bales are easy to handle

10. Feed can be transported to the place where it is needed

11. Feed can be sold

12. Low cost -- no need to invest in storage silo and storage room
