I've for years been bothered like most others are by the presence of corn kernals in manure.A few others near me have added processing units to their choppers to eliminate that problem on their farms.They use a long chop to save on the hp to run the roller and they do a good job.I've asked both of them if they noticed any increase in production per cow and they both reluctantly said "well,no not really",I than asked if the longer chop resulted in a notice in butter fat percentages and again,"well not that I noticed",this time both with a chuckle.If the kernals were really being wasted before and now their being digested,and now the length of chop is increased,why is there no financial bennifits being realized at all from a 6000 dollar investment that takes more fuel and managment to opperate?I'd like to add one to our chopper,but if these results are what's to be expected,than why wast my time and money (or atleast the banks lol)?
