Keep in mind that the guaranteed analysis posted on feeds is a MINUMUM guaranteed analysis. When actually tested by the lab, feeds will almost certainly test higher in fat and protein.
Thats good right?
Yes. My point is, higher quality feeds with advertised slightly lower protein/fat ratios can actually be better that a lesser quality feed that guarantees a slightly higher ratio. In other words, a person shouldn't be too concerned with minor differences in the ratios of different brands.
