Studies in Milk Secretion

milk production of the dam and daughter. The dam's milk 

 production is recorded first as A the highest production, B the 

 next highest group, C the next to the lowest milk production 

 group and D the lowest milk production group. The daughter's 

 milk production is recorded after the dam's, the letters having 

 the same significance. The distribution and limits for these 

 groups are shown in table i, figure 24. The coefficient in front 

 of the letters gives the numbers in each group on the basis of 

 100 for the total. 



Thus, the record for Queen's Raleigh (67 B A -f- 33 D A) 

 shows that all the recorded daughters of his get were in the 

 A class ; 67 per cent or two-thirds of them were out of B class 

 dams and 33 per cent or one-third were out of D class dams. 

 The coefficients therefore represent the percentages of the dif- 

 ferent kinds of daughters which a given bull got from different 

 classes of dams. 



The information on the transmitting qualities of Jersey 

 sires for milk production above described is given in table 4.
