The analyses reported on preceding pages show that while Hawaiian 

 feeding stuffs apparently contain normal amounts of other mineral con- 

 stituents the lime content in many cases is low — so low, indeed, in some 

 of the feeding stuffs that it would be impossible for an animal to eat 

 enough green material to furnish ev T en half of the required 0.13 pound. 

 This is especialh T true with some of the samples of sorghum, Kafir corn, 

 cane tops, and some of the meadow and pasture grasses. The follow- 

 ing table, which summarizes some of the analytical data, will illustrate 

 this point:

A number of samples of grasses, both wild and cultivated, were 

 found to contain lime in excess of these figures. Thus, one sample of 

 sorghum contained 0.15 per cent; two samples of guinea grass, 0.22 and 

 0.17 per cent, respectively; manienie or Bermuda grass, 0.14 per cent; 

 Pasjpalxim dilatatum (samples Nos. 1 and 2), 0.12 and 0.10 per cent, 

 respective^ ; and pili grass, 0.26 per cent. While too few samples 

 have been analyzed to warrant general statements as to average com- 

 position, the available data seem sufficient to warrant the conclusion 

 that forage plants of the grass family grown in Hawaii are generally 

 low in lime, while in some of them the proportion of this constituent 

 is extremely small. 



Ah ordinary ration is made up of concentrated feeds, as well as forage 

 crops or other coarse fodders, and it might be assumed that these feeds 

 would supply any deficiency of mineral matter as well as of protein. 

 Too much reliance should not be placed on concentrated feeds, how- 

 ever, as available data show that some of those analyzed at the station 

 were low in lime. Thus a sample of bran anah T zed was found to con- 

 tain only 0.07 per cent, while two samples of rice bran (Nos. 1 and 2) 

 contained 0.15 and 0.08 per cent, respectively. Over 200 pounds of 

 bran containing only 0.07 per cent lime would be required to supply 

 the necessary 0.13 pound per da}\ The cocoanut meal analyzed con- 

 tained only 0.08 -per cent lime and the two samples of barley 0.05 and 

 0.10 per cent, respectively. It is easily seen from these figures that
