1Assuming a good level of natural production contributing to the diet, the protein level of the starter can be lower
 
2Cholesterol in raw materials should be accounted for and may supply all cholesterol needs (0.25%) for grower pellets (W.G. Dominy, 1999. Oceanic Institute, Hawaii, USA, personal communication).
