Dairy Farming - knowledgebase and resources

Dear All,

Can anyone suggest me the process of making sailage. We are making some tanks by building bricks and the roof will be covered by PPGI sheet.
Now I wanted to know what all we have mix with the choffed fodder. In our area there is a problem of ants,rats coming in if we add salt,butter,jaggery. So will this be ok if we dont add all these?
Just a choffed fodder covered with airtight?
