From these results it is seen that there is no difference in the phos- 

 phorus content of the eggs of the two individuals, but there is a differ- 

 ence in the fat content and also in the protein content. 



EGGS OF UNEQUAL HATCHING POWER 



Two individual hens were picked out that gave contrary results in 

 hatching power. One individual laid eggs which invariably hatched 

 chickens in large percentages. The other individual laid eggs, a few 

 of which hatched. Both were fed and housed in the same pen, and 

 the eggs were incubated under similar conditions. The average 

 weight of the chicks from these two individuals did not indicate, that 

 one chick was more vigorous than the other. The mortality from 

 both lots of chickens was about the same. There was practically 

 nothing except the difference in hatching power of these eggs to indi- 

 cate that one bird was stronger than the other. Tw r o samples of eggs 

 from each individual were examined. Number 3486-29 is the hen 

 producing eggs that hatched well. 



THE FEEDING OF INORGANIC PHOSPHORUS 



From a pen of laying hens being fed the regular ration, ~(the Cornell 

 Ration for Laying Hens), a sample of eggs was taken and the eggs 

 analyzed for the total phosphorus present. The percentages of fat 

 and protein were also determined. Then there was added to the 

 ration some Hen-E-Ta Bone Grit. This Bone Grit was of this compo- 

 sition: CaO 19.04 per cent., P-2 Os 15.30 per cent. Samples of the 

 eggs of the flock were taken from time to time and analyzed. 



The Cornell Ration for Laying Hens 



The following whole grain mixture is fed morning and afternoon 

 in a straw litter : 



Summer. Winter. 



60 Ibs. Wheat. 60 Ibs. Wheat. 



60 Ibs. Corn. 60 Ibs. Corn. 



30 Ibs. Oats. 30 Ibs. Oats. 



30 Ibs. Buckwheat. 



The following mash is fed dry in a hopper kept open during the 

 afternoon only : 



60 Ibs. Cornmeal, 

 60 Ibs. Wheat Middlings. 

 60 Ibs. Wheat Bran. 

 10 Ibs. Alfalfa Meal. 

 10 Ibs. Oil Meal. 

 50 Ibs. Beef Scrap. 

 1 Ib. Salt. 



The fowls eat about half as much mash as whole grain.
