Gowen: Transmission of Butter-fat Percentage 
369 
CROSSBRED COW NO. 11 
This cow is the product of the Jersey and Holstein-Friesian parents shown on the opposite page. 
The appearance of size in the fore quarters and lack of it in the hind quarters is largely due to the 
position in which she is standing. The size and shape of her udder, conformation and other fea- 
tures, are quite well represented. The third graph in Fig. 24 shows the butter-fat percentage of 
this crossbred to be almost intermediate between her high-testing and low-testing parents.

sequently of little interest. They are 
included in the graphs for sake of com- 
pleteness. 
The fifth graph in Figure 24 shows the 
butter-fat percentage for Crossbred 
No. 15 and her Aberdeen-Angus dam, 
Hearthbloom, and Jersey sire, Lake- 
land’s Poet. Very little difference is 
seen in the butter-fat percentages of 
these animals. The eight months but- 
cer-fat percentage for Crossbred No. 
15 is 4.404; for her dam Hearthbloom 
4.404 and for her Jersey sire 4.705. 
Crossbred No. 15 agrees exactly with 
her lower testing parent and is .301 per 
cent less than the higher testing parent. 
Figures 22 and 23 represent Crossbred 
No. 15 and her Aberdeen-Angus dam. 
(Fig. 
The heavy, blocky, well filled conforma- 
tion of Hearthbloom is typical of the 
Aberdeen-Angus breed. There are many 
points of resemblance between Cross- 
bred No. 15 and her dam. 
The sixth graph for Figure 24 shows 
the butter-fat percentage for Crossbred 
No. 16, her Jersey dam College Ruth 
and her Aberdeen-Angus sire, Kayan. 
The photographs of the animals com- 
posing these matings are shown in the 
previous paper of this series. Little 
difference between the butter-fat per- 
centages for the three animals is noted. 
For the first eight months of lactation 
the butter-fat percentage of Crossbred 
No. 16 is 4.894, for College Ruth 4.849 
and for Kayan 4.386. The crossbred
