FGEprNG MINERAL PHOSPHATEs TO LSMBs.-An
experiment was made by Hofmeistcr at one of the
German experimental agricultural stations, as to
the effect of the artificial addition Of phosphates to
the food of lambs. Two lots, each consisting of
three eght-weeks old wethcr lambs, were fed from
MAY 10 December hay and potatoes, with
little salt this diet being selected characteris
tically poor in phOsphates. To one Of these lots
precipitated tnclicic phosphate gwen with the
food but 10 the other. During the last II
DAYS the phosphate diet contained one-fourh more
osphdtc than was supplied by the vegetable food.
The lambs gained about IS pounds per head in SIX
months. Those receiving the phosphate showed
better appetite and drank more water than the other
lot; but there was little difference in the weight.
When slaughtered The only difference between the
two sets was % slightly larger weight OF stomach,
the phosphate. lntlr bones. too were found to be
yathoI heavier, and 10 contain more water and less
fat. The chemical difference simply small ill.,
