Jaku,
The multiflock is 18% and is reccomended for broilers after 30 days of age
None of our mills make it, believe it or not, but that's probably because I'm in Canada not the USA and I was less than impressed last time I went the mill mill in Madoc with the quality of their feed.
The starter/grower is 20% and is recommended for broilers up until 30 days of age.
Peruvian,
Our purina mill does not carry those foods/protein levels, our flock raiser is 18%, we don't have a grower complete locally. We use only Purina feeds and we've had really good experience with them, Purina CANADA that is. Until we took Luna off grain she was eating Purina grains and the layers are on Layena which I have had really good experience with OVER our other locally produced mill whose quality I'm not impressed with.
