Feeding pigs :))) (Farming Simulator 17)

Hello ! Faced with the problem of feeding beastliness : because I have mod for seasons , and until early spring , sow is nothing but grass can't . Respectively and a feed mill pour nothing , and noses asking to eat ... Well , I bought in the store containers with food for pigs , I think all class , feed the afflicted ... yeah , there it was - brought containers to the farm , got on a forklift , and unload can't - not in the feeder, and in General anywhere :)
Attention - the question : what am I doing wrong ? Or in other words how I do with this container to feed pigs ? Who used - respond . Thanks in advance :)
