1 These figures are estimates of requirements and include no margins of safety. 



2 The protein content of rations for growing turkeys from 16 weeks to market weight may be reduced 

 to 16%. 



' May be vitamin A or pro-vitamin A. 



* This amount of calcium need not be incorporated in the mixed feed inasmuch as calcium supplements 

 fed free choice are considered as part of the ration. 



* At least 0.50% of the total feed of starting poults should be inorganic phosphorus. All the phosphorus 

 of non-plant feed ingredients is considered to be inorganic. Approximately 30% of the phosphorus of plant 

 products is non-phytin phosphorus and may be considered as part of the inorganic phosphorus required. 

 Presumably a portion of the requirement of growing and breeding turkeys must also be furnished in inor- 

 ganic form. 



* This figure represents salt or sodium chloride added as such or in marine or fermentation products of 

 high sodium chloride content.
